Definitions

  • the invention relates to a device for thermal treatment, in particular for drying and / or fixing, a continuously moving textile fabric web in a treatment device with at least two treatment zones traversed by the fabric web, according to the preamble of claim 1. Furthermore, the invention is concerned with a treatment device to carry out this procedure.
  • the pollutant emissions from thermal treatment facilities for textile webs must be greatly restricted. If, for example, such a tensioning machine is used to dry and / or fix textile webs after their dyeing with modern textile dyes and so-called carriers, i.e. to dry and / or fix alkaline, chlorine-containing substances, the installation of such a tensioning machine is subject to approval, while in all others Treatment cases this installation is notifiable.
  • thermal treatment of textile material webs dyed with alkaline that is to say chlorine-containing substances
  • corresponding exhaust gas treatment must be carried out directions are installed to keep the pollutant emissions below the prescribed limit. The installation of such exhaust gas treatment devices is necessary even with relatively low exhaust gas emission values if there are complaints from the neighborhood about possible emissions nuisance.
  • a second partial exhaust gas stream is drawn off and freed of the pollutant components contained therein by combustion.
  • the second partial exhaust gas stream heated by this combustion is then used first for preheating the second partial exhaust gas stream supplied to the combustion device and then for reheating the first partial exhaust gas stream before it is released into the atmosphere.
  • the invention is based on the object of further improving a method of the type required in the preamble of claim 1, that the heat consumption and thus the energy costs for exhaust gas purification can still be significantly reduced and at the same time the structural outlay for the necessary parts of the equipment can be significantly reduced.
  • the present invention is based on the knowledge that combined thermal treatment processes, namely in general drying and fixing, are carried out in thermal treatment devices, such as, for example, tensioning machines, in at least two treatment zones which are passed through one after the other by the material web.
  • the textile fabric web is dried in the first treatment zone, water vapor essentially being produced due to the temperatures prevailing there, while fixation is mainly carried out in the second treatment zone, this being carried out at higher temperatures than in the first treatment zone, so that here too more Substances, including spinning and winding oils, evaporate and are added to the exhaust gas to be extracted.
  • this partial exhaust gas stream drawn off from the second treatment zone is loaded with further vaporized substances, such as vaporized spinning and spooling oils and possibly other pollutant substances, with some of the leakage air coming from the web exit slot at this end of the treatment device or second treatment zone.
  • This partial exhaust gas stream drawn off from the second treatment zone is then fed to the combustion device (post-combustion device), initially in the same way as in the process according to German Patent 28 12 966, by preheating it strongly with the exhaust gas partial stream already heated by the combustion of the pollutant components. After this heated partial exhaust gas stream has preheated the partial exhaust gas stream coming directly from the first treatment zone, it is used for further heating of the exhaust gas stream removed from the first treatment zone. Before this heated partial exhaust gas stream is released into the atmosphere, however, it is first used for heating the fresh air to be fed to the treatment device (at the end of the web of material).
  • the partial exhaust gas stream from the second treatment zone is therefore in the combustion after it has been heated device according to the invention successively used firstly for preheating the partial exhaust gas stream coming directly from the second treatment zone, secondly for further heating the exhaust gas stream removed from the first treatment zone and thirdly for heating the fresh air to be newly supplied to the treatment device and thereby sufficiently heated or cooled.
  • the total amount of exhaust gas from the thermal treatment device is reduced to approximately 50% in comparison to known designs by using the exhaust gas from the first treatment zone a second time (in the second treatment zone) after it has been heated to a permissible, regulated extent has been.
  • the thermal illustrated in the drawing Treatment device contains as actual treatment device for a heat treatment of a textile material web 1 continuously moving through it a tensioning machine 2, which is divided into two treatment zones, of which the first treatment zone first passed by the material web 1 contains a dryer part 2a and that of the material web 1 next passed second heat treatment zone forms a fixing part 2b.
  • This tensioning machine 2 can be designed in a conventional manner, ie both the dryer part 2a and the fixing part 2b can be divided into several treatment fields.
  • the material web 1 passes through this tensioning machine 2 continuously in the direction of the arrow 3.
  • the thermal treatment device further contains a combustion device designed as a thermal afterburning device 4, which can be equipped with a burner 5, preferably a gas burner.
  • a combustion device designed as a thermal afterburning device 4, which can be equipped with a burner 5, preferably a gas burner.
  • the web end 2b ⁇ is connected via an exhaust pipe 6 to the thermal afterburning device 4 with the interposition of a first indirect heat exchanger 7.
  • the tensioning machine 2 is also assigned two further indirect heat exchangers, namely a second heat exchanger 8 and a third heat exchanger 9. All three heat exchangers 7, 8, 9 are connected to a main exhaust gas line 10 connected, which starts from the thermal post-combustion device 4 and leads to a chimney 11 and via which an exhaust gas partial flow heated in the thermal post-combustion device 4 first of all one side of the first heat exchanger 7, then - at least partially - one side of the second heat exchanger 8 and then - Again at least partially - one side of the third heat exchanger 9 is fed before it is released into the atmosphere via the chimney 11.
  • a main exhaust gas line 10 connected, which starts from the thermal post-combustion device 4 and leads to a chimney 11 and via which an exhaust gas partial flow heated in the thermal post-combustion device 4 first of all one side of the first heat exchanger 7, then - at least partially - one side of the second heat exchanger 8 and then - Again at least partially - one side of the third heat exchanger 9 is fed before it
  • the second side of the second heat exchanger 8 the entire exhaust gas from the - viewed in the direction of the web (arrow 3) - fed the entire exhaust gas through a gas line 12 to the rear end 2a ⁇ of the dryer part 2a, only to be further heated there in a controlled manner before this entire exhaust gas stream as Fresh gas is introduced into the front end 2b ⁇ of the fixing part 2b, again viewed in the direction of the web.
  • the third heat exchanger 9 downstream of the second heat exchanger 8 in the direction of flow (arrow 13) is on its other side with fresh air (arrow 14) from the space surrounding the treatment device feeds, the fresh air thus heated being introduced via a fresh air supply line 15 into the web end 2aEin of the dryer part 2a and thus the tensioning machine 2.
  • bypass control flaps 16, 16a and 17, 17a and one bypass line 18 and 19 provided in the line sections of this main exhaust line 10, which lead from the first heat exchanger 7 to the second heat exchanger 8 and from the second heat exchanger 8 to the third heat exchanger 9, whereby at least part of the heated partial exhaust gas flow can be directed in a precisely controllable manner on the one hand around the second heat exchanger 8 and on the other hand around the third heat exchanger 9 in the bypass.
  • These bypass devices make it possible to operate the two heat exchangers 8 and 9 in a precisely controllable manner, i.e.
  • the fresh air to be introduced into the web inlet end 2a ⁇ into the dryer part 2a is preferred heated to a temperature which corresponds approximately to the temperature of the exhaust gas drawn off at the rear end 2a ⁇ of the dryer part 2a.
  • the exhaust gas flow drawn off here is then also increased in temperature in a precisely controllable manner in the second heat exchanger 8 (for introduction as a fresh gas quantity into the fixing part 2b), this increased temperature then approximately with the temperature of the partial gas flow drawn off at the end of this fixing part 2b (line 6) matches.
  • the temperature of the hot gas stream circulated there is approximately 200 ° C. while the exhaust gas partial stream drawn off via the exhaust line 6 at the end of the web 2b ⁇ again has a temperature of approximately 180 ° C. If one were to feed the partial exhaust gas stream withdrawn here at this temperature (180 ° C.) directly to the thermal afterburning device 4, this would mean that this device 4 still has to be supplied with a considerable additional part of thermal energy via its burner 5 in order to carry out the thermal afterburning to burn the pollutant components contained in this partial gas stream at about 700 to 800 ° C.
  • the partial exhaust gas stream drawn from the fixing part 2b via the line 6 in the first heat exchanger 7 is first heated to about 550 to 650 ° C, preferably about 600 ° C, with the help of the exhaust gas stream coming from the afterburning device 4 and heated to about 700 to 750 ° C is preheated, only a relatively small additional heat energy supply via the burner 5 to the thermal afterburning device 4 is required.
  • the heated exhaust gas partial flow leaves the first heat exchanger 7 at a temperature of about 350 ° C, at least partially passed over the second heat exchanger 8 and cooled there to about 320 ° C before it flows through the third heat exchanger 9 and is released into the atmosphere at about 250 ° C. via the chimney 11.
