Definitions

  • the invention relates to a dryer for a textile web according to the preamble of claim 1, and a method for drying a textile web.
  • a textile web is fed to the dryer by wraps around the drum to a large extent of the circumference and then discharged from the dryer chamber again.
  • the fresh air is supplied through this opening, which is heated within the dryer chamber and mixed with the circulating air, so that they can absorb the highest possible proportion of moisture.
  • the mixture of circulating air and fresh air flows through the web, at least partially absorbs the moisture of the web and is discharged through the interior of the drum again. From this volume flow, a partial volume flow is removed as exhaust air.
  • the moist exhaust air is discharged through channels above the drums, which requires a complex and expensive seal due to the rotating drums and is maintenance-intensive.
  • supply lines or channels for fresh air have been subsequently added to the dryer chamber, which can for example be coupled to a heat exchanger for heating the fresh air.
  • a previously described dryer is in the DE 102009016019 A1 disclosed.
  • the air circulation of the fresh air takes place at right angles to the withdrawal direction of the moist air, that is perpendicular to the drum axis, whereby the air circulation is disturbed within the dryer chamber.
  • Another disadvantage is due to lack of space, the often expensive conversion, in which the fresh air duct can not be coupled to a heat exchanger. Since the dryers are very dense in a number of different process engineering aggregates that treat the textile web one after the other, there is often a lack of space to retrofit a fresh air duct between the units.
  • the DE 1729499 A1 discloses a screen drum dryer with arranged on the front sides of the screening drums intermediate chambers. Fresh air is supplied to these intermediate chambers and mixed with the drying air. Part of the exhaust air is discharged via the fan room.
  • the intermediate chamber is firmly integrated in the dryer housing and can not be retrofitted with a heat exchanger.
  • the invention comprises a dryer for a textile web, comprising a dryer space and with a plurality of arranged in the dryer room drums, which are at least partially wrapped by the web, wherein the web of heated drying air is flowed through, which flows through an interior the drums is discharged.
  • the invention is characterized in that the dryer has a separate additional chamber, via the fresh air and exhaust air is discharged, wherein within the additional chamber means for distributing the fresh air and / or means for separating the exhaust air from the fresh air and / or means for segmenting the additional chamber are arranged.
  • the connections for the fresh air and the exhaust air to the dryer so that the air flow for the drying process in the dryer room and within the drum is not disturbed.
  • the drying air relaxes, so that their flow rate reduces as it exits the drum by a multiple.
  • the exhaust air is withdrawn with the least impact on the drying process.
  • the fresh air can be sucked in freely by the negative pressure in the additional chamber and directed into the heating and fan room.
  • the fresh air and exhaust air flowing in the additional chamber will be separated from each other by means of segmentation.
  • the additional chamber can be segmented analogously to the number of drums.
  • the individual segments can be partitioned off from one another by walls so that there is no exchange of air between the segments.
  • a distribution of the exhaust air or the fresh air can be generated in several segments. This can also be done via baffles.
  • the invention provides to arrange the additional chamber between an end face of the dryer and a heating and fan room.
  • the removal of the exhaust air from the drying air in the additional chamber is most optimal, since the drying air has the lowest energy level here.
  • the energy loss through the exhaust air is the lowest.
  • the allowed clearly defined interface the use of heat recovery under optimal conditions. With this, the energy balance can be further improved.
  • the fresh air mixes with the drying air.
  • means for heating the fresh air and drying air are arranged within the heating and fan room, the heated drying air has only a short way to the dryer room on which it does not cool.
  • the arrangement of the fans to the heating and fan room to circulate the drying air has the advantage that the dryer can be built relatively compact.
  • the ports may be streamlined to minimize flow losses.
  • the inventive method for drying a textile web is characterized by the steps that drying air is heated and passed into a dryer room in which a web at least partially wraps around at least one arranged within the dryer chamber drum, wherein the heated drying air flows through the web and an interior the drum is discharged, wherein fresh air is supplied to a separate additional chamber and exhaust air is discharged via the additional chamber, wherein the distribution of fresh air within the additional chamber can be influenced.
  • the result is a circulation system in which the drying air withdrawn a partial mass flow of exhaust air and a partial mass flow of fresh air is supplied.
  • the exhaust air is discharged at the point from the drying air at which the drying air has the lowest energy level, namely in the additional chamber.
  • a dryer 1 is shown in the form of a row dryer.
  • three drums 3a, 3b, 3c are arranged one behind the other and with their axes 4a, 4b, 4c in a row.
  • a web 5 is guided via an inlet 6 into the dryer room 2 into it. Via a guide roller 7, the web 5 is guided first below the first drum 3a, then above the second drum 3b and then below the third drum 3c.
  • About a guide roller 8 the web 5 through an outlet 9 from the Drier room 2 brought out.
  • the web 5 is flowed through with heated drying air. The drying air absorbs the moisture of the web 5 and is sucked off through the interior of the drums 3a to 3c.
  • an additional chamber 10 is arranged on the dryer chamber 2, into which the channel 12 for the fresh air 11 and the channel 14 for the exhaust air 13 open.
  • the additional chamber 10 is completely separate and constructed separately from the dryer room 2.
  • the dryer room 2 is connected to air ducts above and below the drums 3a - 3c with the heating and fan room 22.
  • the additional chamber 10 is connected via the frontal opening of the drums 3a - 3c with the dryer room 2.
  • FIG. 2 is the dryer 1 from the FIG. 1 equipped with an optional heat recovery.
  • the same parts have the same reference numerals.
  • the heat exchanger 17 is connected simultaneously with the channel 12, so that the fresh air 11, before it flows into the auxiliary chamber 10, has already experienced a temperature increase by the heat exchanger 17. With this optional retrofittable solution, the thermal efficiency of the dryer 1 can be further increased.
  • the fresh air 11 does not flow directly into the dryer 1, but only into the additional chamber 10, in which a further heating takes place by a mixture with the drying air after the flow through the web 5.
  • this mixing of the fresh air with the drying air was carried out before the flow through the web 5, whereby the temperature of the drying air before the web 5 is influenced.
  • the utilization of the temperature difference between exhaust 13 and Fresh air 11 is sufficient to further increase the thermal efficiency of the dryer 1.
  • FIG. 3 shows a side section through a dryer 1.
  • the fans 19a - 19c which suck the moisture-saturated drying air from the drums 3a - 3c, are flanged to the heating and fan room 22 and via terminals 20a - 20c or adapters with the additional chamber 10 connected. Opposite the drums 3a -3c are also connected via connections with the auxiliary chamber 10.
  • the drying air flows from the drums 3a-3c into the additional chamber 10 and from the additional chamber 10 via the ports 20a-20c into the intake cross-section of the respective fan 19a-19c.
  • the exhaust air from the additional chamber 10 via a channel 14 which is arranged on the front side, removed (see FIG. 1 and 2 ).
  • a fan 15 provides the necessary air flow.
  • the supply of fresh air takes place in the region of the drum 3 c via the additional chamber 10, to which the channel 12 is connected at the end face.
  • the drying air relaxes, so that their flow rate at the exit from the drum 3a, 3b, 3c reduced by a multiple. Furthermore, the fresh air 11 can be sucked in freely by the negative pressure in the additional chamber 10 and fed via this to the heating and fan room 22 with drying air.
  • heating elements 21 may be arranged in the form of heat exchangers, one or more gas heaters or electric heaters, which heat the discharged drying air 11 including the fresh air to the drying temperature.
  • FIG. 4 shows a rear view of the dryer 1, in which the heating and fan room 22 has been hidden.
  • the openings of the drums 3a - 3c can be seen, via which the drums 3a - 3c is connected by means of connections with the additional chamber 10.
  • the fresh air 11 is introduced via a channel 12 into the additional chamber 10.
  • Within the additional chamber 10 are dividers 23 arranged in the form of perforated plates, which segment the additional chamber 10, so that the distribution of the fresh air to the individual fans 19a - 19c can be influenced. It is also possible to influence the distribution of the fresh air within the auxiliary chamber 10 via guide plates, not shown, for example, to separate from the exhaust air.
  • the mixture of fresh and drying air flows through the fans 19 a - 19 c in the heating and fan room 22 a.
  • This is a circulation system, which extracts a partial mass flow in the form of exhaust air and a partial mass flow is supplied in the form of fresh air.
  • the heating and fan room 22 is arranged as a separate chamber in the region of the rear end face of the dryer 1, wherein the additional chamber 10 is arranged therebetween.
  • the drives of the fans 19 a, 19 b, 19 c are arranged, are located inside the fan wheels.
  • a fan 19a, 19b, 19c is associated with a drum 3a, 3b, 3c.
  • the fans 19a, 19b, 19c are connected via connections 20a-20b or adapter with the additional chamber 10 and these also via terminals or adapters with the drums 3a, 3b, 3c.
