Abstract:
Method for purification and reuse of waste air mixed with impurities, from dryers and machine enclosures of machines, comprising the method steps of:a) leading the waste air through at least one condenser adapted for condensing out the impurities in the waste air, and leading the waste air through at least one separator element adapted to remove condensed impurities in the waste air,b) conditioning air parameters of the waste air so as to adhere to predetermined limit values and predetermined process parameters,c) recirculating purified waste air for renewed removal of impurities,d) heating the purified waste air using dryers, without extracting oxygen from the purified waste air, ande) continuing the method beginning at method step a),wherein, via sensor/control sections, air parameters in the dryers, machine enclosures and machines are recorded, and corresponding conditioning of recirculated purified waste air is carried out in order to adhere to predetermined limit values and predetermined process parameters.
