Definitions

  • the invention relates to a method for drying running material webs in dryers operated by means of fresh air, circulating air and exhaust air, and a dryer for carrying out this method.
  • the fresh air introduced into the treatment can be preheated from the treatment, exhaust air directly added to the fresh air, or the heat transfer from the exhaust air can also take place indirectly.
  • the exhaust air from the treatment should be removed in a controlled manner if the moisture content is high.
  • the supply for the fresh air into the treatment room of the dryer can be the entry slot for the web into the dryer housing.
  • the supply for the fresh air can also be a special fresh air connection provided on the dryer housing at the beginning of the treatment room.
  • Circulating air fans can be provided for circulating air within the treatment room for the web, but special external connecting lines with blowers can also be arranged for circulating air from a discharge from the web to the next re-feeding to the web on the dryer housing.
  • the discharge for the exhaust air from the treatment room can be provided in the last dryer field at the end of the treatment or can also be arranged in front of the last dryer field.
  • FIG. 1 A complete direct current flow with air circulation, in which fresh air is introduced via a fresh air connection 15 by means of a blower 19 via a heating register 20 into a nozzle housing 12 into a treatment room 11, is shown in FIG. 1. As indicated by arrows, this is shown by the web 10 treatment agent flowing out of the treatment is fed to a subsequent nozzle housing 12 and there again inflated onto the product web and so on until the end of the treatment. where it is sucked off by means of a blower 21 and discharged from the treatment through the exhaust air connection. To support the flow of the treatment agent and for further heating, as shown in the figure, further blowers 22 and heating registers 20 are switched into the path of the treatment air.
  • FIG. 2 corresponds to that of FIG. 1.
  • This illustration shows, for example, a dryer in which the blowers 22 and heating register 20 are arranged alternately on the two sides of the treatment room 11.
  • the blowers 22 and heating register 20 are arranged alternately on the two sides of the treatment room 11.
  • FIG. 3 shows the side view of a dryer 13 with external direct current flow of the air via external connecting lines 16. Circulating fans 22 with heaters 20 are installed in these lines. The fresh air is introduced into the dryer 13 at the fresh air connection 15 and the exhaust air leaves the dryer through the exhaust air connection 23 .
  • Fig. 4 corresponds essentially to Fig. 1 only that here the exhaust air is removed before the last dryer field 17, whereby, as is desirable and advantageous for the final drying, there is almost a steam atmosphere in this field.
  • a dryer 13 is shown in side view. in the exhaust air of the fresh air for preheating the fresh air is fed directly via a fan 25 and a heater 20.
  • FIG. 6 shows the additional energy recovery from the exhaust air and delivery to the fresh air by means of a heat exchanger 18.
  • the arrangement of a moisture measuring and regulating device is also indicated at 24. Since there is only one exhaust point for the exhaust air. only a single one of these costly devices is required for the method according to the invention.
  • the arrangement according to the invention of guiding the drying air in cocurrent to the direction of travel of the fabric through the treatment results in the following further advantages over the known arrangements and methods.
  • there is less condensation of moisture on the web if the air that is as dry as possible is in the dryer when the cold web runs into the warm dryer.
  • the evaporation capacity is higher. if the cooling limit temperature in the front area of the dryer is low Here there is still enough surface water to evaporate so that the higher ⁇ t and thus the higher heat transfer takes effect.
