Abstract: A semi-open high-temperature heat pump system including a compressor, a direct-contact condenser, a heat exchanger, an evaporator, a water purifier, a cold water pump, a hot water pump, a circulating water pump, and a vacuum pump. A discharge port of the compressor is connected to the direct-contact condenser, the direct-contact condenser is connected to the evaporator via the heat exchanger, and the evaporator is connected to a gas suction port of the compressor via a gas vent on its top. An outlet of the water purifier is separately connected to the compressor, the direct-contact condenser, and the evaporator via the cold water pump. An outlet at the bottom of the evaporator is connected to the direct-contact condenser via the circulating water pump. The vacuum pump is connected above the direct-contact condenser, and the hot water pump is connected below the direct-contact condenser.

Abstract: A water treatment system of coupling a heat pump with multi-effect evaporation that comprises a lithium bromide absorption-type heat pump circulation system, a multi-effect evaporation circulation system and a compression-type heat pump circulation system is provided. The vapor in a tail-end evaporator of the multi-effect evaporation circulation system is introduced into a generator in the absorption-type heat pump to release heat and condense. A dilute solution in an absorber of the absorption-type heat pump is introduced into a first-effect evaporator to be evaporated by a treated water, and a condensation heat of the vapor generated by the generator of the absorption-type heat pump is recovered by an evaporator of a compressor heat pump, and another air source evaporator absorbs heat from ambient air to supply heat for the generator by a heat pump condenser.
