Description

Beschreibung:Description:

Die Erfindung betrifft einen Druckgaskühler, insbesondere für Kompressoren, mit einem Rohrbündel aus parallelen Kühlrohren für die Durchleitung einer Kühlflüssigkeit und mit einem zylindrischen Gehäuse, das an seinem einen Ende geschlossen ist und an seinem anderen Ende eine stirnseitige Öffnung zum Einsetzen des Rohrbündels aufweist, wobei die Kühlrohre einseitig an einen Rohrboden eines in der stirnseitigen Öffnung des Gehäuses befestigbaren Kopfstückes angeschlossen sind und wobei am Umfang des Gehäuses Stutzen für einen Gaseinlass und einen Gasauslass angeordnet sind, die in Gehäuselängsrichtung voneinander beabstandet sind.The invention relates to a compressed gas cooler, in particular for compressors, with a tube bundle of parallel cooling tubes for the passage of a cooling liquid and with a cylindrical housing which is closed at one end and at its other end has an end opening for insertion of the tube bundle, wherein the Cooling tubes are connected on one side to a tube bottom of an attachable in the frontal opening of the housing head piece and wherein at the periphery of the housing stubs for a gas inlet and a gas outlet are arranged, which are spaced apart in the housing longitudinal direction.

Der Druckgaskühler kann beispielsweise in mehrstufigen Verdichteranlagen als Zwischenkühler eingesetzt werden, um das verdichtete Gas zwischen zwei Kompressorstufen auf einen neuen Ansaugzustand abzukühlen. Der Druckgaskühler ist seiner Bauart nach ein Rohrbündelwärmetauscher. Das Kopfstück weist Anschlüsse für Zuführung von Kühlflüssigkeit und den Auslass von Kühlflüssigkeit auf. An dem zum Kopfstück abgewandten Ende der Kühlrohre ist eine Einrichtung vorgesehen, um die Kühlflüssigkeit umzulenken. Die Strömungsrichtung des Gases ist überwiegend quer zu den Kühlrohren des Rohrbündels ausgerichtet, wobei sich bzgl. der Wärmeübertragung zwischen Kühlflüssigkeit und Gas auch eine Mischform aus Kreuzstrom, Gegenstrom und Gleichstrom einstellen kann. Die Stutzen für den Gaseinlass und den Gasauslass können individuell am Gehäusemantel angeordnet werden, und zwar unter Berücksichtigung der an einen Kompressor angeschlossenen Verrohrung.The compressed gas cooler can be used for example in multi-stage compressor systems as an intercooler to cool the compressed gas between two compressor stages to a new intake state. The compressed gas cooler is a tubular heat exchanger in its design. The header has ports for supplying coolant and the outlet of coolant. At the end remote from the head piece of the cooling tubes, a device is provided to divert the cooling liquid. The flow direction of the gas is predominantly oriented transversely to the cooling tubes of the tube bundle, wherein with respect to the heat transfer between the cooling liquid and gas, a mixed form of cross-flow, countercurrent and direct current can be set. The nozzles for the gas inlet and the gas outlet can be individually arranged on the housing shell, taking into account the piping connected to a compressor.

Druckgaskühler des beschriebenen Aufbaus haben sich an sich bewährt. Die Erfindung befasst sich mit der Aufgabe, die Strömungsverteilung und Strömungsführung des Gases innerhalb des Apparates zu optimieren. Das Wärmeübertragungsverhalten soll weiter verbessert und der gasseitige Strömungsdruckverlust reduziert werden.Pressure gas coolers of the structure described have proven themselves. The invention is concerned with the task of flow distribution and flow guidance to optimize the gas within the apparatus. The heat transfer behavior should be further improved and the gas-side flow pressure loss should be reduced.

Ausgehend von einem Druckgaskühler mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass die Kühlrohre des Rohrbündels unter einem Anstellwinkel von 2° bis 10° schräg zur Längsachse des zylindrischen Gehäuses ausgerichtet sind und dass zumindest der Gaseinlass-Stutzen an einem Gehäuseabschnitt angeordnet ist, der infolge der Schrägstellung der Kühlrohre von dem Rohrbündel weiter beabstandet ist als der in Umfangsrichtung gegenüberliegende Gehäuseabschnitt. Dabei ist vorzugsweise zumindest die Mittelachse des Gaseinlass-Stutzens mit einem radialen Versatz quer zur Längsachse des Gehäuses ausgerichtet.Starting from a pressure gas cooler with the features described above, the object is achieved in that the cooling tubes of the tube bundle are aligned at an angle of 2 ° to 10 ° obliquely to the longitudinal axis of the cylindrical housing and that at least the gas inlet nozzle is arranged on a housing portion which is further spaced from the tube bundle due to the inclination of the cooling tubes than the circumferentially opposed housing section. In this case, preferably at least the center axis of the gas inlet nozzle is aligned with a radial offset transversely to the longitudinal axis of the housing.

Die erfindungsgemäßen Maßnahmen bewirken eine verbesserte und druckverlustärmere Anströmung des Rohrbündels. Ferner lassen sich höhere Gasgeschwindigkeiten durch das Rohrbündel realisieren, so dass eine kompaktere Bauweise des Druckgaskühlers möglich ist. Insgesamt verbessert sich auch das Wärmeübertragungsverhalten des Apparates.The measures according to the invention bring about an improved and lower pressure flow of the tube bundle. Furthermore, higher gas velocities can be realized by the tube bundle, so that a more compact design of the compressed gas cooler is possible. Overall, the heat transfer behavior of the apparatus also improves.

Gemäß einer bevorzugten Ausführung der Erfindung sind beide Stutzen für den Gaseinlass und den Gasauslass an Gehäuseabschnitten des Gehäusemantels angeordnet, die infolge der Schrägstellung der Kühlrohre von dem Rohrbündel weiter beabstandet sind als die in Umfangsrichtung jeweils gegenüberliegenden Gehäuseabschnitte, wobei die Mittelachse beider Stutzen jeweils mit einem radialen Versatz quer zur Längsachse des Gehäuses ausgerichtet ist. Die Schrägstellung des Rohrbündels schafft einen größeren Freiraum sowohl im Einströmbereich des Gases als auch im Ausströmbereich. Dadurch, dass die Mittelachse der Stutzen jeweils mit einem radialen Versatz quer zur Längsachse des Gehäuses ausgerichtet ist, wird eine Rotationsströmung des das Gehäuse durchströmenden Gases angeregt.According to a preferred embodiment of the invention, both nozzles for the gas inlet and the gas outlet are arranged on housing portions of the housing shell, which are further spaced from the tube bundle as a result of the inclination of the cooling tubes than the circumferentially opposite housing sections, wherein the central axis of both nozzles each with a radial Offset is aligned transversely to the longitudinal axis of the housing. The oblique position of the tube bundle creates a greater freedom both in the inflow region of the gas and in the outflow region. Characterized in that the central axis of the nozzle each with a radial offset transversely to the longitudinal axis is aligned with the housing, a rotational flow of the housing flowing through the gas is excited.

Das Kopfstück weist vorzugsweise eine an den Mantel des Gehäuses befestigbare Stirnplatte mit einem Einlass für Kühlflüssigkeit und einen Kühlflüssigkeitsauslass sowie einen in Kammern unterteilten Flüssigkeitsraum auf. Die Stirnplatte und der Flüssigkeitsraum bilden dabei zweckmäßig eine als Schweißkonstruktion ausgebildete Einheit, an der der Rohrboden lösbar befestigt ist. Das Rohrbündel mit dem daran angeschlossenen Kopfstück bilden einen austauschbaren Einsatz des Druckgaskühlers, der beispielsweise zu Reinigungszwecken ausgebaut werden kann. Das Gehäuse und das austauschbare Rohrbündel können individuell an unterschiedlich große Kompressoren einer Verdichterbaureihe angepasst werden. Dabei kann auch der die Schrägstellung des Rohrbündels betreffende Anstellwinkel unter Beibehaltung sowohl des konstruktiven Aufbaus des Gehäusemantels als auch des Rohrbündels korrigiert und optimiert werden.The head piece preferably has an end plate which can be fastened to the casing of the housing and has an inlet for cooling liquid and a cooling liquid outlet, and a chamber which is subdivided into chambers. The front plate and the liquid space thereby expediently form a unit designed as a welded construction, to which the tube sheet is detachably fastened. The tube bundle with the connected thereto head piece form a replaceable use of the compressed gas cooler, which can be removed, for example, for cleaning purposes. The housing and the exchangeable tube bundle can be individually adapted to different sized compressors of a compressor series. In this case, the angle of attack of the tube bundle relevant angle of attack can be corrected and optimized while maintaining both the structural design of the housing shell and the tube bundle.

Der in den Figuren dargestellte Druckgaskühler ist seiner Bauart nach ein Rohrbündelwärmetauscher. Er besteht in seinem grundsätzlichen Aufbau aus einem Rohrbündel 1 aus parallelen Kühlrohren 2 für die Durchleitung einer Kühlflüssigkeit und einem zylindrischen Gehäuse 3, das an seinem einen Ende geschlossen ist und an seinem anderen Ende eine stirnseitige Öffnung 4 zum Einsetzen des Rohrbündels 1 aufweist. Die Kühlrohre 2 sind einseitig an einen Rohrboden 5 eines in der stirnseitigen Öffnung 4 des Gehäuses 3 befestigbaren Kopfstückes 6 angeschlossen, welches einen Einlass 7 für die Kühlflüssigkeit sowie einen Auslass 8 für die Kühlflüssigkeit aufweist. An dem von dem Kopfstück 6 abgewandten Ende der Kühlrohre ist eine in an sich bekannter Weise ausgebildete Strömungsumlenkung 9 vorgesehen, so dass jeweils eine gleiche Anzahl von Kühlrohren 2 in der einen Strömungsrichtung und der anderen Strömungsrichtung durchströmt werden. Am Umfang des Gehäuses 3 sind Stutzen 10, 11 für ein Gaseinlass und ein Gasauslass angeordnet, die in Gehäuselängsrichtung voneinander beabstandet sind.The pressure gas cooler shown in the figures is a tube bundle heat exchanger according to its design. It consists in its basic structure of a tube bundle 1 of parallel cooling tubes 2 for the passage of a Coolant and a cylindrical housing 3, which is closed at one end and at its other end an end opening 4 for insertion of the tube bundle 1 has. The cooling tubes 2 are connected on one side to a tube plate 5 of a front piece 4 of the housing 3 attachable head piece 6, which has an inlet 7 for the cooling liquid and an outlet 8 for the cooling liquid. At the end remote from the head piece 6 of the cooling tubes a trained in a conventional manner flow deflection 9 is provided so that in each case an equal number of cooling tubes 2 are flowed through in one flow direction and the other flow direction. At the periphery of the housing 3, nozzles 10, 11 for a gas inlet and a gas outlet are arranged, which are spaced apart in the housing longitudinal direction.

Insbesondere der Schnittdarstellung in Fig. 2 entnimmt man, dass die Kühlrohre 2 des Rohrbündels 1 unter einem Anstellwinkel α von 2 bis 10° schräg zur Längsachse 12 des zylindrischen Gehäuses 3 ausgerichtet sind. Ferner wurde in den Fig. 1 und 2 angedeutet, dass beide Stutzen 10, 11 für den Gaseinlass und den Gasauslass an Gehäuseabschnitten angeordnet sind, die infolge der Schrägestellung der Kühlrohre 2 von dem Rohrbündel 1 weiter beabstandet sind als die in Umfangsrichtung jeweils gegenüberliegenden Gehäuseabschnitte und dass die Mittelachse dieser Stutzen 10, 11 jeweils mit einem radialen Versatz s1, s2 quer zur Längsachse 12 des Gehäuses 3 ausgerichtet ist.In particular, the sectional view in Fig. 2 takes it that the cooling tubes 2 of the tube bundle 1 are aligned at an angle α of 2 to 10 ° obliquely to the longitudinal axis 12 of the cylindrical housing 3. Furthermore, in the Fig. 1 and 2 indicated that both nozzles 10, 11 are arranged for the gas inlet and the gas outlet to housing sections, which are further spaced from the tube bundle 1 due to the inclination of the cooling tubes 2 as the circumferentially opposite housing portions and that the center axis of the nozzle 10, 11 respectively with a radial offset s 1 , s 2 is oriented transversely to the longitudinal axis 12 of the housing 3.

Das Kopfstück 6 weist eine an dem Mantel des Gehäuses 3 befestigbare Stirnplatte 13 mit einem Einlass 7 für Kühlflüssigkeit und einen Kühlflüssigkeitsauslass 8 sowie einen in Kammern 15, 16 unterteilten Flüssigkeitsraum auf. Die Stirnplatte 13 und der Flüssigkeitsraum 14 bilden zweckmäßig eine als Schweißkonstruktion ausgebildete Einheit 17, an der der Rohrboden 5 lösbar befestigt ist.The head piece 6 has an attachable to the shell of the housing 3 face plate 13 with an inlet 7 for cooling liquid and a cooling liquid outlet 8 and a subdivided chambers 15, 16 liquid space. The face plate 13 and the liquid space 14 suitably form as Welded construction formed unit 17 to which the tube sheet 5 is releasably attached.

Durch die erfindungsgemäße Schrägstellung des Rohrbündels 1 innerhalb des Gehäuses 3, insbesondere in Verbindung mit der beschriebenen Anordnung der Stutzen 10, 11 für den Gaseinlass und Gasauslass, kann die Strömungsverteilung und Strömungsführung des Gases durch das Rohrbündel 1 verbessert werden. Im Vergleich zu einem Druckgaskühler gleichen Aufbaus und gleicher Größe, dessen Rohrbündel 1 in der Längsachse des Gehäuses und parallel zu dieser angeordnet ist, lassen sich höhere Gasgeschwindigkeiten bei gleichem Strömungsdruckverlust realisieren. Insgesamt kann das Wärmeübertragungsverhalten verbessert werden.The inventive oblique position of the tube bundle 1 within the housing 3, in particular in connection with the described arrangement of the nozzle 10, 11 for the gas inlet and gas outlet, the flow distribution and flow control of the gas through the tube bundle 1 can be improved. Compared to a compressed gas cooler of the same construction and the same size, the tube bundle 1 is arranged in the longitudinal axis of the housing and parallel to this, higher gas velocities can be realized with the same flow pressure loss. Overall, the heat transfer behavior can be improved.
