Cooling tower vapor condensation recovery device utilizing industrial low-temperature exhaust heat for refrigeration

Abstract

A cooling tower vapor condensation recovery device utilizing industrial low-temperature exhaust heat for refrigeration comprises a cooling tower exhaust channel 1, a condensate water guiding channel 2, an evaporator 3, an exhaust heat source capture generator 4, a refrigerating unit 5, a pure water collector 6, a control part 7, an exhaust heat source 8, a cold energy user 9 and a hot water pipe 10. The evaporator is arranged above the exhaust channel on the top of a cooling tower, the cooling tower exhaust channel containing exhaust heat transmits heat to cold water entering the evaporator, and water contained in exhaust gas flows into the pure water collector through the condensate water guiding channel after being condensed. Heat of the industrial low-temperature exhaust heat source is transmitted to the refrigerating unit through the exhaust heat source capture generator; cold energy obtained through the refrigerating unit can be used for cooling hot water drained out of the evaporator into cold water capable of being used by the cold energy user, and generated hot water is conveyed back to the hot water pipe. The control part is connected with the evaporator, the refrigerating unit and the exhaust heat source capture generator. The industrial low-quality exhaust heat is used as driving force, so that low-quality exhaust heat is efficiently recovered, and water contained in exhaust gas of the cooling tower is also recovered.

AI Technical Summary

Problems solved by technology

Existing cooling towers lose a huge amount of water due to evaporation, which is difficult to effectively recover. Based on the idea of ​​"water intake from air", a special physical process is used to cool down the hot and humid air leaving the tower to condense the water vapor in it to achieve recovery.

There must be industrial waste heat in the production line of the cooling tower, but the low and low temperature waste heat has a large capacity and low quality, so it is difficult to recycle

The existing measures for recovering water contained in cooling tower exhaust are mainly to install dry heat exchangers, electrodes, etc. These methods have their own shortcomings in terms of water collection efficiency and economy
