Title:
APPARATUS FOR CONCENTRATING WASTEWATER
Document Type and Number:
Japanese Patent JP3302956
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for concentrating wastewater which is high in energy efficiency and can obtain high concentration wastewater.
SOLUTION: An apparatus is equipped with an evaporation tank 12 for evaporating water in wastewater and a condensation tank 13 for separating water from air by cooling the vapor generated in the evaporation tank 12. The heat radiation part 31 of a heat cycle apparatus 15 is installed in the tank 12. The tank 12 is evacuated, the wastewater is boiled to evaporate water forcibly. The cooling part 36 of the heat cycle apparatus 15 is installed in the condensation tank 13, vapor is cooled/condensed, and water is separated from air. A porous member 42 is installed between the vapor inlet and the cooling part 36 of the condensation tank 13, and vapor introduced into the tank 13 is divided finely to increase a contact area with the cooling part 36.
