Definitions

  • the invention relates to a method for low-emission treatment, in particular drying of running webs of material such as textile webs or the like, and a device for carrying out this method.
  • the moisture present on the goods and the volatile impurities are evaporated and mixed into the steam atmosphere.
  • Part of this contaminated atmosphere is constantly removed from the dryer and condensed. If necessary, the condensation process can be preceded by a compression process.
  • the contaminants are deposited with the condensate and can be removed in this state using methods known per se without getting into the surrounding atmosphere.
  • the condensation process can, for example, be combined with a post-combustion process for these contaminants. Due to the small volume of these volatile substances, the afterburning system can in this case turn out to be orders of magnitude smaller than the combustion systems for air dryers and accordingly requires lower investment and above all operating costs.
  • the required freedom from air should be achieved from the start by steam filling the treatment room.
  • a device for performing this method can be carried out in such a way that a largely or completely gas or steam-tight dryer housing is designed as a steam bell, in which the entry and exit of the webs from the bottom of the lower part of the housing arranged inlet and Outlet openings occur and that on the dryer housing a discharge connected to a heat exchange device is provided for the steam vapors generated during the drying process. It is expedient to arrange seals at the entry and exit of the webs into and out of the dryer housing, which in a preferred embodiment of a device according to the invention device should be designed as locks connected to suction devices.
  • a dryer which works according to the method according to the invention can have a larger content of goods compared to air dryers for the same dryer performance.
  • the slightly higher investment costs can be more than compensated for by the elimination of the known complex post-combustion systems in air dryers.
  • the webs can be guided in the dryer housing between the inlet and outlet in several passages one above the other or next to one another.
  • the drawing shows a dryer designed as a multi-level frame 18, through the treatment room of which the web 13 is guided for treatment by means of vertical chains (not shown) in a known manner.
  • the dryer housing 10 is, as it were, bell-shaped, ie with the inlet and outlet openings for the web at the bottom of the housing.
  • the treatment room can be largely from air, the even could be brought in with the web, keep it clear, as it is heavier than the steam used for drying and would collect in the bottom of the dryer, from where it could then be removed from the dryer.
  • a portion of the vapor atmosphere provided with contaminants evaporated from the web during drying is continuously led out of the dryer housing 10 through a line 15 and condensed in a heat exchanger 14.
  • the contaminants are deposited with the condensate and can be collected in a collecting container 20, from which they are then disposed of using known methods can without getting into the surrounding atmosphere.
