Definitions
- the invention relates to a method for washing a textile web according to the preamble of claim 1 and a wide-width washing machine according to the preamble of claim 2.
- REPLACEMENT LEAF Arranged in which the liquid which has passed through the material web and is loaded with the washed-out residues is collected without pressure and pumped back into the rinsing unit.
- the invention has for its object to achieve an improved washing effect in a generic method and such a wide-washing machine.
- An essential point of the present invention is that steam is injected into the web on one side and is drawn off in the vicinity of the injection area on the other side, together with the residues remaining in the web, under the effect of a strong negative pressure. It has been shown that only the blowing up of the steam under a clear overpressure with practically simultaneous suction from the other side under a vacuum of at least 0.2 bar results in a substantial increase in the washing effect.
- the negative pressure should therefore not only suffice to achieve a mere removal of the medium that has passed through the web, but should result in a strong flow through the web, so that the residues just hit by the inflated steam are, as it were, torn out of the web in this state .
- REPLACEMENT LEAF leave slightly increased moisture so that the heat content of the web remains essentially unchanged and in any case not much heat is transported out of the process in this way.
- the expression "in the neighborhood" for the mutual position of the outlet opening and the inlet opening is intended to mean that the application of the steam on one side of the web and the suction from the other side are not at a greater distance from one another in the conveying direction and one corresponding time interval, but in one go. Even if it is not imperative that the outlet opening and the inlet opening lie exactly opposite one another, and also not that both with their limitations lie against the web under pressure (although this is the preferred embodiment), the distances that occur should be of the openings or their boundaries in the conveying direction of the web and perpendicular to the web surface are of the order of magnitude of the openings in the conveying direction, that is to say in practice they are in the order of millimeters or at most a few centimeters. This close “neighborhood” makes it possible to maintain the pressures required on the pressure side and the suction side to achieve the washing effect, without having to use excessively dimensioned pressure and suction pumps.
- the residues consist of organic treatment agents or auxiliaries or comprise agents which have considerable molecular sizes.
- the idea is that these large molecules are stimulated by the energy supply until they are broken down or split up and removed by suction in the "neighborhood" in this more mobile state before they can come together again to form larger and less mobile units.
- REPLACEMENT LEAF Pressure and suction devices arranged directly opposite each other on both sides of the web are known per se from DE 31 03 359 C 2, but the medium moved through the web here is not steam, but foam, and it is also not about the Wa ⁇ rule, but on the contrary to apply a treatment agent to the web.
- Claims 4 to 11 show various configurations of the outlet or inlet opening which are possible within the scope of the invention.
- An important feature is the adjustability of the openings according to claim 12, because this enables adaptation to different goods.
- the formation and arrangement of the openings e.g. in the case of loose thin goods, in the case of tightly knocked solid goods, in the case of pile goods and even in the case of carpets, it must be different.
- the adjustability is particularly advantageous in cooperation with a control and regulating device according to claim 13, which allows the washing process to be regulated as a function of goods-specific parameters, that is to say to design it automatically.
- the control and regulating device can comprise several controllers assigned to the individual components of the machine; however, it is preferred to combine the essential or all of the control and regulating elements in a central control and regulating unit (claim 15).
- this can relate in particular to the flow quantity and / or the flow pressure and what the extent of the openings in the conveying direction, ie the width relates to the slot nozzles, in the manner reproduced in claim 16.
- a special control variable, which is characteristic of the washing effectiveness, is the concentration of the residues washed out of the material web in the extracted medium. This can be included in the regulation according to claim 18.
- the concentration of the residues remaining on the material web can also be determined and the corresponding concentration value can be used for regulation (claim 19).
- a gas in addition to the steam e.g. Air and / or a liquid, e.g. Injecting water into the web and sucking it back together with the steam on the other side (claim 20).
- FIG. 4 shows a circuit diagram of a special embodiment of a wide-range washing machine according to the invention.
- a textile web 1 is indicated, which is horizontally conveyed in the spread position and has a certain permeability, so that steam inflated onto the web 1 can pass through the web 1.
- an injection device 10 is provided above the web 1 with an outlet opening 10 ′ running across the width of the web, that is perpendicular to the plane of the drawing.
- the outlet opening 10 ' is delimited by a slot nozzle 40, the Expansion in the conveying direction 1 'of the web 1, ie the slot width 41 is adjustable.
- a possible range for the slot width 41 is approximately 1 to 2 mm.
- a suction device 20 with an inlet opening 20 ' is provided below the web 1, which is formed by a slot nozzle 50 with an adjustable slot width 51.
- the expansion of the outlet openings in the slot nozzles 40, 50 in the width direction of the web is adaptable to the width of the web 1, so that there is no loss of steam or suction power.
- the slot widths 41 and 51 are the same and the slot nozzles 40, 50 lie exactly opposite one another.
- the outlet edges of the slot nozzles 40, 50 bear against the web 1 under slight pressure from both sides.
- steam is generated under an overpressure of at least 0.2 bar, better still somewhat higher, e.g. in the range of 0.5 bar on the top of the web 1 and blown into it, which is indicated by the arrow I.
- the medium passed through the web 1 i.e. a mixture of steam, water and the residues released from the material web 1 is suctioned off with a vacuum of at least 0.2 bar, better still 0.5 bar, which is symbolized by the arrow A.
- the slot nozzle 40 corresponds to that according to FIG. 1.
- the web 1 lies against the nozzle edges.
- the slit nozzle 50 'of the suction device 20 has a width 51' which is approximately twice as large as the slit nozzle 40 and, with its trailing limitation, is offset by a distance 52 'in the conveying direction 1'.
- the distance 52 ' is smaller than the width 41 of the slot nozzle 40, so that the slot nozzle 50' in the region 54 'is still partially below the slot nozzle 40, but extends beyond it in the conveying direction 1
- REPLACEMENT LEAF stretches so that in region 53, in addition to the steam remaining in the web, the condensate formed there and the residues to be removed, air is sucked through the web 1 from the outside. In the area 52 'there is no nozzle opposite the outlet opening 10', but the amount of steam which exits through the web 1 into the outside space is relatively small, since in particular in the first phase the inflated steam immediately blows up and in The web of material condenses and remains largely in the slot nozzle 50 'until it is reached.
- the slit nozzle 50 "of the suction device 20 is approximately three times as wide as the slit nozzle 40 of the injection device 10 and is offset with respect to it with its trailing edge by a distance 52" in the conveying direction 1 ', which is larger than the width 41 of the slot 40. It is thus no overlap of the slit nozzles 40 and 50 'more' before.
- the embodiment of Fig. 3 differs from the two previous embodiments in that the edges of the slot nozzle 41 are located slightly above the web, i.e. maintain a certain distance from the web 1 perpendicular to its surface. Part of the steam blown in the direction of arrow I will therefore flow laterally parallel to the web and partially condense on it or, insofar as it passes through the slot nozzle 50 ", from the negative pressure prevailing there in the direction of arrow A into the web 1 - and are torn through them. However, the web 1 will always rest on the edges of the slit nozzles 50, 50 ', 50 ", since it is sucked in by the negative pressure prevailing there.
- outlet opening 10 'and the inlet opening 20' should always remain in the vicinity of one another, which should mean that the two should not be apart from one another by more than the order of magnitude of a slot nozzle width. Both the transfer amounts 54 'and 54 "as well
- the distance amount 42 should therefore only be a few millimeters or centimeters. It is therefore not intended to inject the steam in the direction of arrow I at one point and to suction in the direction of arrow A at a point, for example, one meter behind it. Rather, the steam should be applied and injected into the web 1 and immediately or practically immediately sucked off again.
- FIG. 4 corresponds to the embodiment and arrangement of outlet opening 10 'and inlet opening 20' of the embodiment according to FIG. 1.
- the web 1 is guided over guide rollers 2 to 5, of which at least the guide roller 5 is driven by a drive motor 6 , drawn between the Injetechnischseinric device 10 and the suction device 20.
- the injection device 10 and the suction device 20 have an injection slot nozzle 11 and a suction slot nozzle 21, which are pressed against one another by means of pressing devices 12 and 22 with the web 1 being interposed.
- the interior of the injection device 10 is connected to the interior of the suction device 20 only separated by the web 1.
- the inner spaces are essentially sealed off from the outside.
- the injection slot nozzle 11 and the suction slot nozzle 21 each have an adjusting slide 13 or 23, which can be adjusted via an adjusting motor 14 or 24.
- the setting is carried out in such a way that the expansion of the slot nozzles 11, 21 in the conveying direction 1 ', that is to say the length L, over which the web 1 is clamped between the edges of the slot nozzles 11 and 21, can be adjusted and adapted if necessary.
- the length of the slot nozzles 11, 21, that is to say their extension perpendicular to the conveying direction 1 'of the web 1 (ie perpendicular to the plane of the drawing), is adapted to the width of the web 1. You can do this using the slot
- SPARE BLADE comprise nozzles 11, 21 which are telescopically inserted into one another and displaceable against one another.
- the interior of the suction device 20 is connected to the suction side of a suction pump 25, which sucks the mixture which has passed through the goods train 1, compresses it and supplies it to a heat exchanger / condenser 26.
- the condensate coming cooled from the heat exchanger 26 with the residual substances contained therein and removed from the web 1 is fed from a condensate pump 27 to a washing medium inlet line 33 via a valve 28.
- the flow quantity of the washing medium in the inlet line 33 is sensed by a flow sensor 32, the output signal of which is fed to a control device 7.
- the pressure-side outlet of the condensate pump 27 is connected via a test flow valve 29 to a test device 30, which generates output signals which reflect the contamination state of the concentrate or its concentration of residual substances taken up.
- the condensate examined is fed back into the inlet line, but can also be discarded since the amount of liquid still required for the examination is small.
- the feedback valve 28 and the test flow valve 29 are controlled by the central control and regulating unit 7.
- the inlet line 33 is connected to a fresh water supply via a fresh water valve 31 controlled by the central control and regulating unit 7 and leads through the heat exchanger 26, so that returned condensate mixed with fresh water can be heated in the heat exchanger 26.

- a water pipe 9 is provided, via which waste water
- REPLACEMENT LEAF can be discharged from the steam generator 19 via a valve 17 controlled by the central control and regulating unit 7. This makes it possible to evaporate the recirculated condensate in the steam generator 19 and to keep it in the steam generator 19 at a consistently high concentration of residues, so that the discharged amounts of waste water are small or the residues removed from the web 1 in the Waste water in high concentration.
- the steam generator 19 delivers steam to the injection device 10 via a steam control valve 16 controlled by the central control and regulating unit 7.
- a pump 8 controlled by the central control and regulating unit 7 is provided in order to directly return the condensate bypassing the steam generator 19 to add to the steam behind the valve. If necessary, another washing liquid or fresh water can also be added here. In this way, the steam can be influenced in its degree of saturation.
- the admixture is again regulated by the central control and regulating unit 7.
- a gas, in particular air is provided for the steam. This is particularly advantageous if, owing to the given conditions on the web 1, large flow quantities per unit of time are necessary.
- the central control and regulating unit 7 works here in such a way that the entire washing process corresponds to goods-specific data that can be input via an input device 34 and treatment-specific data such as e.g. the conveyor speed is regulated and controlled.

Description
Verfahren zum Waschen einer textilen Warenbahn und entsprechende Breitwaschmaschine Process for washing a textile web and corresponding wide-washing machine
Die Erfindung betrifft ein Verfahren zum Waschen einer textilen Warenbahn gemäß dem Oberbegriff des Anspruchs 1 und eine Breitwaschmaschine nach dem Oberbegriff des Anspruchs 2.The invention relates to a method for washing a textile web according to the preamble of claim 1 and a wide-width washing machine according to the preamble of claim 2.
Breitwaschmaschinen für textile Warenbahnen sind in verschiedenen Ausführungen bekannt. Ein wesentliches Problem besteht in vielen Fällen darin, daß im Innern der Warenbahn aus den üblichen Vorbehandlungs- und Naßveredelungsstufen (Entschlichten, Auswaschen von Präparationen, Färberei, Druckerei, Appretur) Reststoffe der entsprechenden Art zu¬ rückbleiben. Insbesondere bei sehr schweren oder dichten Warenbahnen kann der Aufwand an Energie und Waschwasser bei den bekannten Waschverfahren sehr groß werden, wenn eine hinreichende Entfernung der Reststoffe erzielt werden soll.Wide washing machines for textile webs are known in various designs. A major problem in many cases is that residues of the corresponding type remain in the interior of the web from the customary pretreatment and wet finishing stages (desizing, washing out of preparations, dyeing, printing, finishing). In the case of very heavy or dense webs in particular, the expenditure of energy and washing water in the known washing processes can become very great if sufficient removal of the residues is to be achieved.
Aus der DE 20 59 308 A 1 sind ein gattungsgemäßes Ver¬ fahren und eine solche Anordnung zum Ausspülen von Wasch¬ lauge aus Gewebeartikeln bekannt, bei welchen von oben auf die zwischen Siebbändern horizontal geführte Warenbahn Dampf aus einer Spüleinheit in Mischung mit mitgerissenem Wasser aus einer sich quer über die Breite der Warenbahn erstrek- kenden Schlitzdüse aufgeblasen wird. Mit etwas Abstand un¬ terhalb des unteren Siebbandes ist unter der Schlitzdüse eine mit einer Eintrittsöffnung versehene AuffangeinrichtungFrom DE 20 59 308 A 1 a generic method and such an arrangement for rinsing washing liquor out of fabric articles are known, in which steam from a rinsing unit in a mixture with entrained water from a steaming unit is passed from above onto the web horizontally guided between sieve belts slit nozzle extending across the width of the web is inflated. At some distance below the lower sieve belt there is a collecting device provided with an inlet opening under the slot nozzle
ERSATZBLATT angeordnet, in der die durch die Warenbahn hindurchgetretene mit den ausgewaschenen Reststoffen beladene Flüssigkeit drucklos aufgefangen und in die Spüleinheit zurückgepumpt wird.REPLACEMENT LEAF Arranged in which the liquid which has passed through the material web and is loaded with the washed-out residues is collected without pressure and pumped back into the rinsing unit.
Versuche haben gezeigt, daß die mit einer solchen An¬ ordnung erzielbaren Wascheffekte diejenigen herkömmlicher Wascheinheiten nicht nennenswert übersteigen.Tests have shown that the washing effects which can be achieved with such an arrangement do not appreciably exceed those of conventional washing units.
Der Erfindung liegt die Aufgabe zugrunde, bei einem gattungsgemäßen Verfahren und einer solchen Breitwasch¬ maschine eine verbesserte Waschwirkung zu erzielen.The invention has for its object to achieve an improved washing effect in a generic method and such a wide-washing machine.
Diese Aufgabe wird in ihrem verfahrensmäßigen Aspekt durch die in Anspruch 1 wiedergegebene Erfindung gelöst.This object is achieved in its procedural aspect by the invention reproduced in claim 1.
Ein wesentlicher Punkt der vorliegenden Erfindung liegt darin, daß Dampf in die Warenbahn auf deren einer Seite hinein injiziert und in der Nachbarschaft des Injektions¬ bereichs auf der anderen Seite samt dem in der Warenbahn verbliebenen Reststoffen unter der Wirkung eines kräftigen Unterdrucks wieder abgezogen wird. Es hat sich gezeigt, daß erst das Aufblasen des Dampfes unter deutlichem Überdruck bei praktisch gleichzeitigem Absaugen von der anderen Seite her unter einem Unterdruck von mindestens 0,2 bar eine we¬ sentliche Steigerung der Waschwirkung ergibt. Der Unterdruck soll also nicht nur zur Erzielung einer bloßen Wegförderung des durch die Warenbahn hindurchgetretenen Mediums ausrei¬ chen, sondern eine kräftige Durchströmung der Warenbahn ergeben, so daß die gerade von dem aufgeblasenen Dampf ge¬ troffenen Reststoffe in diesem Zustand gewissermaßen aus der Bahn herausgerissen werden. Dadurch ist in relativ einfacher Weise ein wirksameres Waschen möglich (gegebenenfalls zu¬ sätzlich zu üblichen Waschvorgängen) . Der Energieaufwand bleibt in Grenzen, da der Dampf bzw. dessen Kondensat im wesentlichen vollständig abgezogen werden und im Kreislauf verbleiben können. Je nach Einstellung des Dampfes kann eine feuchte Warenbahn die Breitwaschmaschine mit wenig geringe¬ rer, eine trockene Warenbahn die Breitwaschmaschine mit nurAn essential point of the present invention is that steam is injected into the web on one side and is drawn off in the vicinity of the injection area on the other side, together with the residues remaining in the web, under the effect of a strong negative pressure. It has been shown that only the blowing up of the steam under a clear overpressure with practically simultaneous suction from the other side under a vacuum of at least 0.2 bar results in a substantial increase in the washing effect. The negative pressure should therefore not only suffice to achieve a mere removal of the medium that has passed through the web, but should result in a strong flow through the web, so that the residues just hit by the inflated steam are, as it were, torn out of the web in this state . As a result, more effective washing is possible in a relatively simple manner (if appropriate in addition to conventional washing processes). The energy expenditure remains limited, since the steam or its condensate are essentially completely drawn off and can remain in the circuit. Depending on the setting of the steam, a wet web of fabric can wash the wide-washing machine with a little less, a dry web of fabric can wash the wide-washing machine with only a small amount
ERSATZBLATT geringfügig erhöhter Feuchtigkeit verlassen, so daß der Wärmeinhalt der Warenbahn im wesentlichen unverändert bleibt und jedenfalls auf diesem Wege nicht viel Wärme aus dem Prozeß heraustransportiert wird.REPLACEMENT LEAF leave slightly increased moisture so that the heat content of the web remains essentially unchanged and in any case not much heat is transported out of the process in this way.
Der Ausdruck "in der Nachbarschaft" für die gegenseiti¬ ge Lage der Austrittsöffnung und der Eintrittsöffnung soll besagen, daß das Aufbringen des Dampfes auf der einen Seite der Warenbahn und das Absaugen von der anderen Seite nicht in einem größeren Abstand voneinander in Förderrichtung und einem dem entsprechenden zeitlichen Abstand erfolgen sollen, sondern in einem Zuge. Wenn es auch nicht zwingend ist, daß die Austrittsöffnung und die Eintrittsöffnung einander genau gegenüber liegen, und auch nicht, daß beide mit ihren Be¬ grenzungen unter Druck an der Warenbahn anliegen (wenn gleich dies die bevorzugte Ausführungsform ist), so sollen die vorkommenden Abstände der Öffnungen bzw. ihrer Begren¬ zungen in Förderrichtung der Warenbahn und senkrecht zur Bahnfläche in der Größenordnung der Ausdehnungen der Öff¬ nungen in Förderrichtung liegen, also in der Praxis jeweils in der Größenordnung von Millimetern oder höchstens wenigen Zentimetern liegen. Durch diese enge "Nachbarschaft" ist es möglich, die zur Erzielung der Waschwirkung erforderlichen Drücke auf der Druckseite und der Saugseite aufrechtzuer¬ halten, ohne übermäßig dimensionierte Druck- und Saugpumpen einsetzen zu müssen.The expression "in the neighborhood" for the mutual position of the outlet opening and the inlet opening is intended to mean that the application of the steam on one side of the web and the suction from the other side are not at a greater distance from one another in the conveying direction and one corresponding time interval, but in one go. Even if it is not imperative that the outlet opening and the inlet opening lie exactly opposite one another, and also not that both with their limitations lie against the web under pressure (although this is the preferred embodiment), the distances that occur should be of the openings or their boundaries in the conveying direction of the web and perpendicular to the web surface are of the order of magnitude of the openings in the conveying direction, that is to say in practice they are in the order of millimeters or at most a few centimeters. This close "neighborhood" makes it possible to maintain the pressures required on the pressure side and the suction side to achieve the washing effect, without having to use excessively dimensioned pressure and suction pumps.
Durch die Dampfbeaufschlagung wird der Warenbahn bzw. den darauf befindlichen Reststoffen thermische und mechanische Energie zugeführt. Die Reststoffe bestehen in vielen Fällen aus organischen Behandlungsmitteln oder Hilfs¬ mitteln oder umfassen solche Mittel, die erhebliche Molekül¬ größen aufweisen. Die Vorstellung geht dahin, daß diese großen Moleküle durch die Energiezufuhr bis zur Zerlegung oder Aufspaltung angeregt und durch das Absaugen "in der Nachbarschaft" in diesen beweglicheren Zustand von der Bahn entfernt werden, bevor sie sich wieder zu größeren und weniger beweglichen Einheiten zusammenfinden können.By applying steam, thermal and mechanical energy is supplied to the web or the residues on it. In many cases, the residues consist of organic treatment agents or auxiliaries or comprise agents which have considerable molecular sizes. The idea is that these large molecules are stimulated by the energy supply until they are broken down or split up and removed by suction in the "neighborhood" in this more mobile state before they can come together again to form larger and less mobile units.
ERSATZBLATT Unmittelbar einander gegenüberliegend zu beiden Seiten der Warenbahn angeordnete Druck- und Saugeinrichtungen sind für sich genommen aus der DE 31 03 359 C 2 bekannt, doch ist das durch die Warenbahn hindurchbewegte Medium hier nicht Dampf, sondern Schaum, und es geht auch nicht um das Wa¬ schen, sondern im Gegenteil um das Aufbringen eines Behand¬ lungsmittels auf die Warenbahn.REPLACEMENT LEAF Pressure and suction devices arranged directly opposite each other on both sides of the web are known per se from DE 31 03 359 C 2, but the medium moved through the web here is not steam, but foam, and it is also not about the Wa ¬ rule, but on the contrary to apply a treatment agent to the web.
In ihrem apparativen Aspekt ist die Erfindung in An¬ spruch 2 wiedergegeben.In its apparatus aspect, the invention is given in claim 2.
Es hat sich gezeigt, daß die Waschwirkung noch verbes¬ sert wird, wenn der Überdruck auf der Seite der Dampfinjek- tion und/oder der Unterdruck auf der Absaugseite mindestens jeweils 0,5 bar betragen (Anspruch 3).It has been shown that the washing effect is still improved if the overpressure on the steam injection side and / or the underpressure on the suction side is at least 0.5 bar in each case (claim 3).
In den Ansprüchen 4 bis 11 sind verschiedene im Rahmen der Erfindung mögliche Ausgestaltungen der Austritts- bzw. Eintrittsöffnung wiedergegeben.Claims 4 to 11 show various configurations of the outlet or inlet opening which are possible within the scope of the invention.
Ein wichtiges Merkmal ist die Verstellbarkeit der Öff¬ nungen gemäß Anspruch 12, weil dadurch eine Anpassung an verschiedene Waren möglich ist. Um die optimale Waschwirkung zu erzielen ist es verständlich, daß Ausbildung und Anord¬ nung der Öffnungen z.B. bei lockerer dünner Ware, bei dicht¬ geschlagener fester Ware, bei Polware und gar bei Teppichen unterschiedlich sein muß.An important feature is the adjustability of the openings according to claim 12, because this enables adaptation to different goods. In order to achieve the optimal washing effect, it is understandable that the formation and arrangement of the openings e.g. in the case of loose thin goods, in the case of tightly knocked solid goods, in the case of pile goods and even in the case of carpets, it must be different.
Besonders vorteilhaft zur Geltung kommt die Einstell¬ barkeit im Zusammenwirken mit einer Steuer- und Regelein¬ richtung nach Anspruch 13, die es erlaubt, den Waschvorgang in Abhängigkeit von warenspezifischen Parametern zu regeln, daß heißt selbstätig auszugestalten.The adjustability is particularly advantageous in cooperation with a control and regulating device according to claim 13, which allows the washing process to be regulated as a function of goods-specific parameters, that is to say to design it automatically.
Die Steuer- und Regeleinrichtung kann mehrere den ein¬ zelnen Komponenten der Maschine zugeodnete Regler umfassen; bevorzugt ist jedoch die Zusammenfassung der wesentlichen oder aller Steuer- und Regelglieder in einer zentralen Steuer- und Regeleinheit (Anspruch 15).The control and regulating device can comprise several controllers assigned to the individual components of the machine; however, it is preferred to combine the essential or all of the control and regulating elements in a central control and regulating unit (claim 15).
Dies kann gemäß Anspruch 15 insbesondere die Strömungs¬ menge und/oder den Strömungsdruck betreffen und, was die Ausdehnung der Öffnungen in Förderrichtung, d.h. die.Breite der Schlitzdüsen betrifft, in der in Anspruch 16 wiedergege¬ benen Weise realisiert werden.According to claim 15, this can relate in particular to the flow quantity and / or the flow pressure and what the extent of the openings in the conveying direction, ie the width relates to the slot nozzles, in the manner reproduced in claim 16.
Eine wichtige Einflußgröße für den Waschvorgang ist die Fördergeschwindigkeit der Warenbahn, die nach Anspruch 17 in die Regelung einbezogen werden kann.An important influencing variable for the washing process is the conveying speed of the web, which can be included in the regulation according to claim 17.
Eine besondere Regelgröße, die für die Waschwirksamkeit charakteristisch ist, ist die Konzentration der aus der Warenbahn ausgewaschenen Reststoffe in dem abgesaugten Medi¬ um. Diese kann gemäß Anspruch 18 in die Regelung einbezogen werden.A special control variable, which is characteristic of the washing effectiveness, is the concentration of the residues washed out of the material web in the extracted medium. This can be included in the regulation according to claim 18.
Alternativ kann auch die Konzentration der auf der Warenbahn verbliebenen Reststoffe bestimmt werden und der entsprechende Konzentrationswert zur Regelung dienen (An¬ spruch 19) .Alternatively, the concentration of the residues remaining on the material web can also be determined and the corresponding concentration value can be used for regulation (claim 19).
Je nach den auszuwaschenden Reststoffen und der Beson¬ derheit der vorliegenden Warenbahn kann es zweckmäßig sein, außer dem Dampf zusätzlich ein Gas z.B. Luft und/oder eine Flüssigkeit, z.B. Wasser in die Warenbahn zu injizieren und zusammen mit dem Dampf auf der anderen Seite wieder abzusau¬ gen (Anspruch 20).Depending on the residues to be washed out and the particularity of the web, it may be appropriate to add a gas in addition to the steam, e.g. Air and / or a liquid, e.g. Injecting water into the web and sucking it back together with the steam on the other side (claim 20).

In den Fig. 1 bis 3 ist eine textile Warenbahn 1 ange¬ deutet, die in ausgebreiteter Lage horizontal gefördert wird und eine gewisse Durchlässigkeit aufweist, sodaß auf die Warenbahn 1 aufgeblasener Dampf durch die Warenbahn 1 hin¬ durchtreten kann.1 to 3, a textile web 1 is indicated, which is horizontally conveyed in the spread position and has a certain permeability, so that steam inflated onto the web 1 can pass through the web 1.
Bei der Ausführungsform nach Fig. 1 ist oberhalb der Warenbahn 1 eine Injektionseinrichtung 10 mit einer quer über die Breite der Bahn, also senkrecht zur Zeichenebene verlaufenden Austrittsöffnung 10' vorgesehen. Die Austritts¬ öffnung 10' ist durch eine Schlitzdüse 40 begrenzt, deren Ausdehnung in Förderrichtung 1' der Warenbahn 1, d.h. deren Schlitzbreite 41 verstellbar ist. Ein in Betracht kommender Bereich für die Schlitzbreite 41 ist etwa 1 bis 2mm.In the embodiment according to FIG. 1, an injection device 10 is provided above the web 1 with an outlet opening 10 ′ running across the width of the web, that is perpendicular to the plane of the drawing. The outlet opening 10 'is delimited by a slot nozzle 40, the Expansion in the conveying direction 1 'of the web 1, ie the slot width 41 is adjustable. A possible range for the slot width 41 is approximately 1 to 2 mm.
Unterhalb der Warenbahn 1 ist im Ausführungsbeispiel nach Fig. 1 eine Absaugeinrichtung 20 mit einer Ein¬ trittsöffnung 20' vorgesehen, die durch eine Schlitzdüse 50 mit verstellbarer Schlitzbreite 51 gebildet ist. Die Aus¬ dehnung der Austrittsöffnungen bei den Schlitzdüsen 40,50 in Breitenrichtung der Warenbahn, ist der Breite der Warenbahn 1 anpaßbar, so daß keine Verluste an Dampf oder Saugleistung eintreten.1, a suction device 20 with an inlet opening 20 'is provided below the web 1, which is formed by a slot nozzle 50 with an adjustable slot width 51. The expansion of the outlet openings in the slot nozzles 40, 50 in the width direction of the web is adaptable to the width of the web 1, so that there is no loss of steam or suction power.
In dem Ausführungsbeispiel sind die Schlitzbreite 41 und 51 gleich und liegen die Schlitzdüsen 40,50 einander genau gegenüber. Die Austrittsränder der Schlitzdüsen 40,50 liegen unter leichtem Druck von beiden Seiten an der Waren¬ bahn 1 an.In the exemplary embodiment, the slot widths 41 and 51 are the same and the slot nozzles 40, 50 lie exactly opposite one another. The outlet edges of the slot nozzles 40, 50 bear against the web 1 under slight pressure from both sides.
In der Injektionseinrichtung 10 wird Dampf unter einem Überdruck von mindestens 0,2 Bar, besser noch etwas höher, z.B. im Bereich von 0,5 Bar auf die Oberseite der Warenbahn 1 auf- und in diese hineingeblasen, was durch den Pfeil I angedeutet ist. Auf der gegenüberliegenden, d.h. in Fig. 1 unteren Seite wird das durch die Warenbahn 1 hindurchgetre¬ tene Medium, d.h. ein Gemisch aus Dampf, Wasser und den aus der Warenbahn 1 herausgelösten Reststoffen mit einem Unter¬ druck von mindestens 0,2 Bar, besser von 0.5 Bar abgesaugt, was durch den Pfeil A symbolisiert sein soll.In the injection device 10, steam is generated under an overpressure of at least 0.2 bar, better still somewhat higher, e.g. in the range of 0.5 bar on the top of the web 1 and blown into it, which is indicated by the arrow I. On the opposite, i.e. in Fig. 1 lower side the medium passed through the web 1, i.e. a mixture of steam, water and the residues released from the material web 1 is suctioned off with a vacuum of at least 0.2 bar, better still 0.5 bar, which is symbolized by the arrow A.
Bei der Ausführungsform nach Fig. 2 entspricht die Schlitzdüse 40 derjenigen nach Fig. 1. Die Warenbahn 1 liegt an den Düsenrändern an. Die Schlitzdüse 50' der Absaugein¬ richtung 20 jedoch hat eine etwa doppelt so große Breite 51' wie die Schlitzdüse 40 und ist mit ihrer nacheilenden Be¬ grenzung um eine Strecke 52' in Förderrichtung 1' versetzt. Die Strecke 52' ist kleiner als die Breite 41 der Schlitzdü¬ se 40, so daß die Schlitzdüse 50' in dem Bereich 54'noch teilweise unter der Schlitzdüse 40 gelegen ist, sich aber in ihrer Ausdehnung in Förderrichtung 1 über diese hinaus erIn the embodiment according to FIG. 2, the slot nozzle 40 corresponds to that according to FIG. 1. The web 1 lies against the nozzle edges. However, the slit nozzle 50 'of the suction device 20 has a width 51' which is approximately twice as large as the slit nozzle 40 and, with its trailing limitation, is offset by a distance 52 'in the conveying direction 1'. The distance 52 'is smaller than the width 41 of the slot nozzle 40, so that the slot nozzle 50' in the region 54 'is still partially below the slot nozzle 40, but extends beyond it in the conveying direction 1
ERSATZBLATT streckt, so daß in dem Bereich 53 außer dem in der Warenbahn verbliebenen Dampf, dem dort gebildeten Kondensat und den zu entfernenden Reststoffen Luft aus dem Außenraum durch die Warenbahn 1 hindurchgesaugt wird. In dem Bereich 52' liegt der Austrittsöffnung 10' keine Düse gegenüber, doch ist die Menge an Dampf, die hier durch die Warenbahn 1 hindurch in den Außenraum austritt, relativ gering, da besonders in der ersten Phase der aufgeblasene Dampf sogleich auf und in der Warenbahn kondensiert und überwiegend bis zum Erreichen der Schlitzdüse 50' in dieser verbleibt.REPLACEMENT LEAF stretches so that in region 53, in addition to the steam remaining in the web, the condensate formed there and the residues to be removed, air is sucked through the web 1 from the outside. In the area 52 'there is no nozzle opposite the outlet opening 10', but the amount of steam which exits through the web 1 into the outside space is relatively small, since in particular in the first phase the inflated steam immediately blows up and in The web of material condenses and remains largely in the slot nozzle 50 'until it is reached.
In dem Ausführungsbeispiel nach Fig. 3 ist die Schlitz¬ düse 50" der Absaugeinrichtung 20 etwa dreimal so breit wie die Schlitzdüse 40 der Injektionseinrichtung 10 und gegen¬ über dieser mit ihrer nacheilenden Kante um eine Strecke 52" in Förderrichtung 1' versetzt, die größer ist als die Breite 41 der Schlitzdüse 40. Es liegt also keine Überdeckung der Schlitzdüsen 40 und 50" mehr' vor.In the exemplary embodiment according to FIG. 3, the slit nozzle 50 "of the suction device 20 is approximately three times as wide as the slit nozzle 40 of the injection device 10 and is offset with respect to it with its trailing edge by a distance 52" in the conveying direction 1 ', which is larger than the width 41 of the slot 40. It is thus no overlap of the slit nozzles 40 and 50 'more' before.
Außerdem unterscheidet sich das Ausführungsbeispiel der Fig. 3 dadurch von den beiden vorangehenden Ausführungsbei- spielen, daß die Ränder der Schlitzdüse 41 etwas oberhalb der Warenbahn gelegen sind, d.h. einen gewissen Abstand von der Warenbahn 1 senkrecht zu deren Fläche einhalten. Ein Teil des im Sinne des Pfeiles I aufgeblasenen Dampfes wird also seitlich parallel zur Warenbahn abströmen und sich teilweise auf dieser kondensieren bzw. , soweit er über die Schlitzdüse 50" gerät, von dem dort herrschenden Unterdruck im Sinne des Pfeiles A in die Warenbahn 1 hinein- und durch diese hindurchgerissen werden. Auf den Rändern der Schlitz¬ düsen 50,50' ,50" wird die Warenbahn 1 allerdings immer an¬ liegen, da sie von dem dort herrschenden Unterdruck ange¬ saugt wird.In addition, the embodiment of Fig. 3 differs from the two previous embodiments in that the edges of the slot nozzle 41 are located slightly above the web, i.e. maintain a certain distance from the web 1 perpendicular to its surface. Part of the steam blown in the direction of arrow I will therefore flow laterally parallel to the web and partially condense on it or, insofar as it passes through the slot nozzle 50 ", from the negative pressure prevailing there in the direction of arrow A into the web 1 - and are torn through them. However, the web 1 will always rest on the edges of the slit nozzles 50, 50 ', 50 ", since it is sucked in by the negative pressure prevailing there.
Die Austrittsöffnung 10' und die Eintrittsöffnung 20' sollen aber stets in Nachbarschaft zueinander verbleiben, was bedeuten soll, daß beide um nicht mehr als die Größen¬ ordnung einer Schlitzdüsenbreite voneinander entfernt sein sollen. Sowohl die Versetzungsbeträge 54' und 54" als auchHowever, the outlet opening 10 'and the inlet opening 20' should always remain in the vicinity of one another, which should mean that the two should not be apart from one another by more than the order of magnitude of a slot nozzle width. Both the transfer amounts 54 'and 54 "as well
ERSATZBLATT der Abstandsbetrag 42 sollen also nur wenige Millimeter oder Zentimeter betragen. Es ist also nicht vorgesehen, die In¬ jektion des Dampfes im Sinne des Pfeiles I an einer Stelle und das Absaugen im Sinne des Pfeiles A an einer beispiels¬ weise ein Meter dahinter gelegenen Stelle vorzunehmen. Der Dampf soll vielmehr aufgebracht und in die Warenbahn 1 inji¬ ziert und sogleich oder praktisch sogleich wieder abgesaugt werden.REPLACEMENT LEAF the distance amount 42 should therefore only be a few millimeters or centimeters. It is therefore not intended to inject the steam in the direction of arrow I at one point and to suction in the direction of arrow A at a point, for example, one meter behind it. Rather, the steam should be applied and injected into the web 1 and immediately or practically immediately sucked off again.
Das Ausführungsbeispiel der Fig. 4 entspricht hinsicht¬ lich Ausbildung und Anordnung von Austrittsöffnung 10' und Eintrittsöffnung 20' dem Ausführungsbeispiel nach Fig. 1. Die Warenbahn 1 wird über Führungswalzen 2 bis 5, von denen mindestens die Führungswalze 5 über einen Antriebsmotor 6 angetrieben ist, zwischen der Injektionseinric tung 10 und der Absaugeinrichtung 20 hindurchgezogen. Die Injektionsein¬ richtung 10 und die Absaugeinrichtung 20 weisen eine Injek- tions-Schlitzdüse 11 bzw. eine Absaug- Schlitzdüse 21 auf, welche mittels Andrückeinrichtungen 12 bzw. 22 unter Zwi¬ schenlage der Warenbahn 1 gegeneinander gedrückt werden. Dadurch steht der Innenraum der Injektionseinrichtung 10 mit dem Innenraum der Absaugeinrichtung 20 nur durch die Waren¬ bahn 1 getrennt in Verbindung. Nach außen sind die Innenräu¬ me bei diesem Ausführungsbeispiel im wesentlichen dicht abgeschlossen.The embodiment of FIG. 4 corresponds to the embodiment and arrangement of outlet opening 10 'and inlet opening 20' of the embodiment according to FIG. 1. The web 1 is guided over guide rollers 2 to 5, of which at least the guide roller 5 is driven by a drive motor 6 , drawn between the Injektionseinric device 10 and the suction device 20. The injection device 10 and the suction device 20 have an injection slot nozzle 11 and a suction slot nozzle 21, which are pressed against one another by means of pressing devices 12 and 22 with the web 1 being interposed. As a result, the interior of the injection device 10 is connected to the interior of the suction device 20 only separated by the web 1. In this exemplary embodiment, the inner spaces are essentially sealed off from the outside.
Die Injektions-Schlitzdüse 11 und die Absaug-Schlitzdü- se 21 weisen jeweils einen Verstellschieber 13 bzw. 23 auf, der über einen Verstellmotor 14 bzw. 24 einstellbar ist. Die Einstellung erfolgt hierbei derart, daß die Ausdehnung der Schlitzdüsen 11,21 in Förderrichtung 1', also die Länge L, über welche die Warenbahn 1 zwischen den Berandungen der Schlitzdüsen 11 und 21 eingeklemmt ist, eingestellt und bedarfsweise angepaßt werden kann. Die Länge der Schlitzdü¬ sen 11,21, also ihre Ausdehnung senkrecht zur Förderrichtung 1' der Warenbahn 1 (also senkrecht zur Zeichenebene) ist der Breite der Warenbahn 1 angepaßt. Hierzu können die SchlitzThe injection slot nozzle 11 and the suction slot nozzle 21 each have an adjusting slide 13 or 23, which can be adjusted via an adjusting motor 14 or 24. The setting is carried out in such a way that the expansion of the slot nozzles 11, 21 in the conveying direction 1 ', that is to say the length L, over which the web 1 is clamped between the edges of the slot nozzles 11 and 21, can be adjusted and adapted if necessary. The length of the slot nozzles 11, 21, that is to say their extension perpendicular to the conveying direction 1 'of the web 1 (ie perpendicular to the plane of the drawing), is adapted to the width of the web 1. You can do this using the slot
ERSATZBLÄTT düsen 11,21 teleskopartig ineinander gesteckte und gegenein¬ ander verschiebbare Elemente umfassen.SPARE BLADE comprise nozzles 11, 21 which are telescopically inserted into one another and displaceable against one another.
Der Innenraum der Absaugeinrichtung 20 steht mit der Saugseite einer Saugpumpe 25 in Verbindung, die das durch die Warenbahή 1 hindurchgetretene Gemisch absaugt, verdich¬ tet und einem Wärmetauscher/Kondensator 26 zuführt. Das aus dem Wärmetauscher 26 abgekühlt kommende Kondensat mit den darin enthaltenen, aus der Warenbahn 1 entfernten Reststof¬ fen wird von einer Kondensatpumpe 27 über ein Ventil 28 einer Waschmedium-Eingangsleitung 33 zugeführt. Die Strö¬ mungsmenge des Waschmediums in der Eingangsleitung 33 wird über einen Strömungsfühler 32 abgetastet, dessen Ausgangs¬ signal einer Regeleinrichtung 7 zugeführt werden.The interior of the suction device 20 is connected to the suction side of a suction pump 25, which sucks the mixture which has passed through the goods train 1, compresses it and supplies it to a heat exchanger / condenser 26. The condensate coming cooled from the heat exchanger 26 with the residual substances contained therein and removed from the web 1 is fed from a condensate pump 27 to a washing medium inlet line 33 via a valve 28. The flow quantity of the washing medium in the inlet line 33 is sensed by a flow sensor 32, the output signal of which is fed to a control device 7.
Weiterhin steht der druckseitige Ausgang der Kondensat¬ pumpe 27 über ein TestStromventil 29 mit einem Testgerät 30 in Verbindung, welches Ausgangssignale erzeugt, die den Verunreinigungszustand des Konc nsats bzw. dessen Konzen¬ tration an aufgenommenen Restscoffen wiederspiegeln. Das untersuchte Kondensat wird im hier gezeigten Ausführungsbei- spiel wieder der Eingangsleitung zugeführt, kann aber auch verworfen werden, da die zur Untersuchung noch notwendige Flüssigkeitsmenge gering ist. Das Rückführventil 28 und das Teststromventil 29 werden von der zentralen Steuer- und Regeleinheit 7 gesteuert.Furthermore, the pressure-side outlet of the condensate pump 27 is connected via a test flow valve 29 to a test device 30, which generates output signals which reflect the contamination state of the concentrate or its concentration of residual substances taken up. In the exemplary embodiment shown here, the condensate examined is fed back into the inlet line, but can also be discarded since the amount of liquid still required for the examination is small. The feedback valve 28 and the test flow valve 29 are controlled by the central control and regulating unit 7.
Die Ei „gangsleitung 33 steht über ein von der zentralen Steuer- und Regeleinheit 7 gesteuertes Frischwasserventil 31 mit einer Frischwasserzufuhr in Verbindung und führt durch den Wärmetauscher 26, sodaß zurückgeführtes Kondensat ver¬ mischt mit Frischwasser im Wärmetauscher 26 aufgeheizt wer¬ den kann.The inlet line 33 is connected to a fresh water supply via a fresh water valve 31 controlled by the central control and regulating unit 7 and leads through the heat exchanger 26, so that returned condensate mixed with fresh water can be heated in the heat exchanger 26.
Die aus dem Wärmetauscher 26 kommende vorgeheizte Flüs¬ sigkeit wird einem Dampferzeuger 19 zugeführt, der mittels einer von der zentralen Steuer- und Regeleinheit 7 gesteuer¬ ten Heizung 18 beheizt werden kann. Bei dem Dampferzeuger 19 ist eine Ab asserleitung 9 vorgesehen, über welche AbwasserThe preheated liquid coming from the heat exchanger 26 is fed to a steam generator 19 which can be heated by means of a heater 18 controlled by the central control and regulating unit 7. In the steam generator 19, a water pipe 9 is provided, via which waste water
ERSATZBLATT aus dem Dampferzeuger 19 über ein von der zentralen Steuer- und Regeleinheit 7 gesteuertes Ventil 17 abgelassen werden kann. Dadurch ist es möglich, im Dampferzeuger 19 ein Ein¬ dampfen des rückgeführten Kondensats vorzunehmen und dieses im Dampferzeuger 19 auf einer gleichbleibend hohen Konzen¬ tration an Reststoffen zu halten, sodaß die abgelassenen Abwassermengen gering sind bzw. die aus der Warenbahn 1 entfernten Reststoffe in dem Abwasser in hoher Konzentration anfallen.REPLACEMENT LEAF can be discharged from the steam generator 19 via a valve 17 controlled by the central control and regulating unit 7. This makes it possible to evaporate the recirculated condensate in the steam generator 19 and to keep it in the steam generator 19 at a consistently high concentration of residues, so that the discharged amounts of waste water are small or the residues removed from the web 1 in the Waste water in high concentration.
Der Dampferzeuger 19 liefert Dampf über ein von der zentralen Steuer- und Regeleinheit 7 gesteuertes Dampfregel¬ ventil 16 zur Injektionseinrichtung 10. Darüber hinaus ist eine von der zentralen Steuer- und Regeleinheit 7 gesteuerte Pumpe 8 vorgesehen, um rückgeführtes Kondensat unter Umgehung des Dampferzeugers 19 direkt dem Dampf hinter dem Ventil beizumischen. Gegebenenfalls kann hier auch eine andere Waschflüssigkeit oder Frischwasser beigemengt werden. Auf diese Weise kann der Dampf in seinem Sättigungsgrad beeinflußt werden. Die Beimengung erfolgt auch hier wieder geregelt durch die zentrale Steuer- und Regeleinheit 7. Weiterhin ist vorgesehen, dem Dampf ein Gas, insbesondere Luft beizumengen. Dies ist insbesondere dann von Vorteil, wenn auf Grund der gegebenen Verhältnisse an der Warenbahn 1 große Strömungsmengen pro Zeiteinheit notwendig sind.The steam generator 19 delivers steam to the injection device 10 via a steam control valve 16 controlled by the central control and regulating unit 7. In addition, a pump 8 controlled by the central control and regulating unit 7 is provided in order to directly return the condensate bypassing the steam generator 19 to add to the steam behind the valve. If necessary, another washing liquid or fresh water can also be added here. In this way, the steam can be influenced in its degree of saturation. The admixture is again regulated by the central control and regulating unit 7. Furthermore, a gas, in particular air, is provided for the steam. This is particularly advantageous if, owing to the given conditions on the web 1, large flow quantities per unit of time are necessary.
Die zentrale Steuer- und Regeleinheit 7 arbeitet hier derart, daß der gesamte Waschvorgang entsprechend warenspe¬ zifischen Daten, die über ein Eingabegerät 34 eingebbar sind und behandlungsspezifischen Daten wie z.B. der Förderge¬ schwindigkeit, geregelt und gesteuert wird. Die Überwachung des Waschvorgangs entsprechend den AusgangsSignalen des Testgeräts 30 erfolgt über ein Anzeigegerät 35. Durch stän¬ dige Überwachung der Fördergeschwindigkeit und der Strδ- mungsmenge des rückgeführten Kondensats durch den Strömungs- mengenfühler 32 und das Testgerät 30 ist es möglich, eine echte Regelung des Waschvorgangs durchzuführen, wobei der übergeordnete Regelkreis das Testgerät 30 mit umfaßt. EsThe central control and regulating unit 7 works here in such a way that the entire washing process corresponds to goods-specific data that can be input via an input device 34 and treatment-specific data such as e.g. the conveyor speed is regulated and controlled. The washing process is monitored in accordance with the output signals of the test device 30 via a display device 35. By continuously monitoring the conveying speed and the flow rate of the returned condensate by the flow rate sensor 32 and the test device 30, it is possible to control the washing process properly perform, the higher-level control loop also includes the test device 30. It
ERSATZBLATT können über die zentrale Steuer- und Regeleinheit 7 nicht nur der Dampfdurchsatz, sondern auch die Länge L der "Be¬ handlungsstrecke" und gegebenenfalls (bei Ausführungsformen nach den Fig. 2 und 3) die Längen der Versatzstrecken 54', 54" so eingestellt werden, daß optimale Waschergebnisse erzielbar sind. Ein wichtiger Punkt besteht darin, daß die Waschwirkung ohne die Aufbringung zusätzlicher Chemikalien allein durch die Wirkung des Dampfes herbeigeführt wird.REPLACEMENT LEAF Not only the steam throughput, but also the length L of the "treatment section" and optionally (in the case of embodiments according to FIGS. 2 and 3) the lengths of the offset sections 54 ', 54 "can be set in this way via the central control and regulating unit 7 An important point is that the washing effect is brought about by the action of the steam without the application of additional chemicals.
Anstatt die Reststoffkonzentration im abgesaugtem Medium zu messen (oder zusätzlich hierzu) kann auch die Konzentration der auf der Warenbahn 1 nach dem Absaugen verbliebenen Reststoffe in einer Restchemikalien-Meßeinrich¬ tung 36 bestimmt werden, die in Förderrichtung 1' hinter der Absaugeinrichtung 20 angeordnet und in Fig. 4 strichpunk¬ tiert angedeutet ist. Das Meßsignal wird über die Signallei¬ tung 37 der zentralen Steuer- und Regeleinheit 7 zugeführt und zur Regelung verwendet.Instead of measuring (or in addition to this) the residue concentration in the extracted medium, the concentration of the residues remaining on the web 1 after suction can also be determined in a residual chemical measuring device 36 which is arranged in the conveying direction 1 'behind the suction device 20 and in 4 is indicated by dash-dotted lines. The measurement signal is fed to the central control and regulating unit 7 via the signal line 37 and used for regulation.
Bei orientierenden Versuchen mit einer Anordnung nach Fig. 3 wurde eine offene Handtuchware aus 100% Baumwolle mit 25g/Liter Indanthren RS blauflüssig blau eingefärbt. Der Versuchsaufbau wies folgende Maße auf:In orientational tests with an arrangement according to FIG. 3, an open towel made of 100% cotton with 25 g / liter indanthrene RS was dyed blue blue. The experimental setup had the following dimensions:

Es wurden mit diesem Versuchsaufbau die folgenden Ver¬ gleichsversuche mit den jeweils angegebenen Ergebnissen durchgeführt:The following comparative tests were carried out with the results given in each case using this experimental setup:
a) Nur Dampf aufblasen - Effekt gering b) Dampf mit 0,5 bar auf¬ blasen und Wasser auf¬ aufgießen - Effekt gering c) wenig Dampf aufblasen und mit 15 inches Hg ab¬ saugen Effekt gering d) Dampf mit 0,5 bar auf¬ blasen und mit 15 inches Hg absaugen Effekt erheblich deutliche Entfärbung (fast weiß)a) Only inflate steam - effect low b) Inflate steam at 0.5 bar and pour water onto it - low effect. c) Inflate little steam and suck off with 15 inches Hg. Effect low. d) Inflate steam at 0.5 bar and with 15 inches Hg suck off effect significantly clear discoloration (almost white)
Ersichtlich kommt es also darauf an, daß mit einem deutlichen Druck Dampf aufgedüst und gleichzeitig mit erheb¬ lichem Unterdruck abgesaugt wird. Obviously, it is important that steam is injected with a clear pressure and at the same time suctioned off with considerable vacuum.
