<p>PURPOSE:To recover most of waste heat for attaining energy saving and much contribution to the prevention of environmental pollution by providing a means for performing heat exchange between discharge air and feed air and a means for removing the volatile substances from said discharge air. CONSTITUTION:A part of the circulating air is branched from a discharge air line 6 and led into a device 12 for recovering heat in the discharged air and removing volatile matters. Said circulating air is cooled at the heat exchanging section 13 and volatiles matters removing section 14 in said device 12 and then it is led to an open air (stack) 15 and exhausted into the atmosphere. In the meanwhile, the atmospheric air taken in from an atmospheric air suction port 16 and passed through a blower 17 is supplied into the device 12 from an inlet 18 to reach the heat exchanging section 13 where said air is heated by discharge air heat brought into said section 13 from the discharge air line 6 and the thus heated air is further led to an air mixing section 3 where it is mixed with the main circulating air.</p> |
