Title:
HEAT PUMP MULTI-EFFECT EVAPORATION COUPLED WATER TREATMENT SYSTEM AND OPERATING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/083300
Kind Code:
A1
Abstract:
Disclosed in the present invention is a heat pump multi-effect evaporation coupled water treatment system, comprising a lithium bromide absorption type heat pump circulation system, a multi-effect evaporation circulation system and a compression-type heat pump circulation system. Vapor in an end evaporator of the multi-effect evaporation circulation system is introduced into a generator in an absorption-type heat pump for cooling and condensation, and a dilute solution in an absorber of the absorption-type heat pump is introduced into a single-effect evaporator for evaporation via treatment water, condensation heat from the vapor generated by the generator of the absorption-type heat pump is recovered by means of an evaporator of a compressor heat pump, and heat from ambient air is absorbed by means of another air source evaporator, and thus heat energy is supplied to the generator by means of a heat pump condenser. According to the present invention, the absorption-type heat pump can output a heat source at 100ºC or higher to provide heat for the multi-effect evaporation system, and the compressor heat pump with stable performance is used to recover absorption-type vapor condensation heat; in addition, heat required for regeneration of a generator solution is provided by using air source principles, and thus the evaporation treatment of sewage or waste water can be achieved without needing an additional heat source.
