EVAPORATING CONDENSATION APPARATUS FOR WASTEWATER

摘要

PROBLEM TO BE SOLVED: To obtain a small-size apparatus which can be produced at a reasonable cost and by which the safety and effective evaporating condensation can be realized by installing an air-feeding means in the channel between a wastewater evaporating part and a condensation part so that the steam generated in a wastewater vaporizing part may be sucked and also may be blown to a condensing part where the steam is condensed. SOLUTION: Wastewater is stored in a storage tank 110 of an evaporating part 100 and an evaporation-promoting means 113 is driven rotatively by energizing a heater H. Steam is generated caused by evaporating the wastewater. The steam is taken by a sirocco fan 230 and is fed to a heat exchanger 210 of a condensation part 21 via a channel L1. The steam is moved in the passage of the heat exchanger 210 and is cooled by the air which is fed by a fan F and flows in another channel, and a part of the steam is liquefied. The condensate is recovered into a condensate tank 80 through a drain D or the like. A supplemental pump 70 is driven by a controller C based on the output of a level-detecting means SR, and the wastewater is fed to the storage tank 110 when liquid in the storage tank 110 has reduced.
