HEAT PUMP SALT WATER DESALINATOR Russian patent published in 2018 - IPC C02F1/04 

FIELD: technological processes.

SUBSTANCE: invention relates to installations for the desalination of salt water, namely to the creation of a heat pump salt water desalination plant, and can be used for local fresh water supply of settlements, residential, public and industrial buildings. Heat pump salt water desalinator contains a salt water evaporation chamber with liquid sprayers, a closed circuit of the working substance equipped with a compressor, a condenser, evaporator, throttle valve, fresh and salt water circulation pumps, ejector, automatic air vent, heat exchanger for pre-cooling the vapor-liquid mixture, the circuit of the working fluid, which uses desalinated water, includes an ejector connected to an evaporation chamber and a heat exchanger for pre-cooling the vapor-liquid mixture, as well as a freshwater outlet to the consumer. Salt water evaporation chamber is equipped at the top with a steam separator. New portion of the original salt water enters the evaporation chamber from the environment through a regenerative heat exchanger, heating from the discharged brine.

EFFECT: technical result of the invention is to reduce the specific energy consumption for the desalination of salt water, the reduction of the salinity of the produced fresh water, the reduction of corrosion and scale formation during operation.
