Definitions

  • the invention relates to a method for heat treating a web by inflation of steam according to the preamble of claim 1 and a corresponding device according to the preamble of claim 9.
  • a suitable device hereinafter called steam dryer, has a vapor-tight housing with an inlet and an outlet slot and one Transport device for the web.
  • the heat treatment can be a drying, a drying with a fixation or a include pure fixation. All fields of the steam dryer, or only some of the Fields that are operated with steam.
  • the continuous webs to be treated are prefers textile webs. It can also be paper or film webs or the like.
  • the Material webs are transported by a transport device, for example with tension chains a roller conveyor or with a screen belt, conveyed through the steam dryer.
  • the Transport device can also be provided with nozzle boxes provided with air cushion nozzles have free-floating guidance of the web.
  • DE 27 27 971 describes a device for the thermal treatment of a continuous moving web of goods known to reduce the entry of indoor air into a Treatment chamber on the outside of in a wall of the treatment chamber provided web inlet and outlet openings each have a nozzle system as a seal is provided.
  • a nozzle system includes a first one adjacent the chamber opening A pair of nozzles connected to a point in the treatment chamber which is at a negative pressure is, as well as a subsequent second pair of nozzles, with the pressure side of a suction side Atmosphere connected fan is connected.
  • Another drying installation namely for paper webs, is from DE-A 42 26 107 known.
  • This drying system has a dryer with additional nozzle boxes on both sides of the entry and exit slots.
  • the nozzle boxes are provided with nozzle openings, the blowing direction of which is directed at an acute angle to the web guide plane onto the inlet gap.
  • To the nozzle boxes are sawtooth-shaped on average.
  • the penetration of cold Ambient air through the inlet slit is supposed to be matched between Exit velocity of the blowing jets and that existing inside the dryer Have negative pressure prevented.
  • the vacuum prevents it from escaping when drying volatile solvents.
  • a steam dryer should be at overpressure operate.
  • a path running through the devices for heat treatment distinguishing heat treatment device namely a hanging loop damper, in which the material web by means of supporting rods attached to a circulating chain in free hanging Grinding through the treatment is known from DE 29 51 299.
  • This The hanging loop damper is equipped with an air or Provide steam lock. There are none about the construction and operation of the lock Information provided.
  • a generic steam dryer in which the Steam is blown onto a continuously moving web and is constantly circulated the steam flow and also the web speed in a hanging loop damper much lower, i.e. the requirements for a lock are also lower.
  • the object of the invention is a generic method for heat treating a continuous web of goods by inflating steam according to the preamble of Claim 1 and a corresponding generic device according to the preamble of claim 9 to develop so that if possible no air, neither air with Ambient temperature still heated air penetrates into the interior of the device. Moreover should avoid condensation of the steam in the entrance area on the web become.
  • steam is additionally in a lock in front of the inlet slot of the Inflated housing on the web.
  • the steam becomes the web surrounding air displaces, causing air to enter the interior of the housing is prevented.
  • the web is inflated by the steam through the large heat capacity of the steam warmed up with high efficiency. This reduces the risk formation of condensate in the entrance area inside the housing.
  • a steam speed of 20 to 40 m / s according to claim 2 ensures that the on Steam impinging on the material web displaces the air boundary layer and the entry of air into it Housing is avoided.
  • part of the exhaust steam is fed into the lock according to claim 4. This saves an additional source of steam.
  • Exhaust steam which is removed according to claim 5 from the front region of the device, is not or significantly less contaminated with oils from the preparation agents than it is from the rear of the device.
  • heated air is blown onto the in the lock before the inflation Material web inflated. This leads to a preheating of the web and prevents it Touching steam emerging from the lock with cold ambient air, resulting in a Condensation of the steam would result.
  • Slot nozzles allow a particularly intensive contact of the Steam or the heated air with the web and good heat transfer.
  • Figure 1 shows the schematic representation of a side view of the first three fields Steam dryer according to the invention with a lock and those connected to the lock Cables.
  • the lock is in an enlarged view in Figure 2 using a longitudinal section and in Figure 3 can be seen on the basis of a cross section along the line AA of Figure 2.
  • a device according to the invention in other words a device according to the invention Steam dryer, has a vapor-tight, heat-insulated housing 1 with an inlet slot 2 and an outlet slot not shown in FIG. 1 and also not shown in FIG. 1 Transport device shown for a in the transport direction 3 through the steam dryer current web 4 on.
  • Transport device shown for a in the transport direction 3 through the steam dryer current web 4 on.
  • At least one field is a steam field 5 with a device for guiding steam in a circulating air process with a, dashed shown, circulating air fan 6 and a heating device, not shown, and with Nozzle boxes 7 with nozzle openings aimed at the web 4.
  • One or more of the remaining fields can be air fields with a device for guiding Mostly heated air in the recirculation process also with a recirculation fan and with Be nozzle boxes with nozzle openings aimed at the material web.
  • all six fields are steam fields 5, in each of which several, for Example two, above and below the web 4, across the web 4 extending nozzle boxes 7 are arranged.
  • the manifold 9 leads to an exhaust fan 10.
  • the inlet slot 2 is on a front wall 11 of the housing 1 and the outlet slot a rear wall of the housing 1 attached.
  • the transport device forms inside the Housing 1 for the web 4 a horizontal transport plane on which the inlet slot 2nd and the outlet slot is arranged; d. H. it is designed so that the web 4 through the inlet slot 2, through the housing 1 and through the outlet slot on the horizontal Transport level is guided.
