The invention relates to a
heat pump seawater desalination fully-coupled circulation
system and method and belongs to the field of energy power. The
system is characterized by further comprising a
seawater desalination subsystem which comprises a
seawater pump, a preheater connected with an outlet of the seawater pump, a seawater heater connected with an outlet of the preheater, a humidifying
tower connected with a seawater side outlet of the seawater heater, and an
evaporation condenser connected with a wet air side outlet of the humidifying
tower. Heat released in the condensing process of a
refrigerant is used for heating seawater, hot sea water and low-temperature saturated moist air make ful contact in the humidifying
tower to complete heating and humidifying of wet air, then the high-temperature wet air releases heat in the
evaporation condenser to be condensed,
fresh water is separated out, and meanwhile concentrated seawater discharged out of the humidifying tower is used for preheating fed seawater. According to the
heat pump seawater desalination fully-coupled circulation
system and method, a compressor in a mechanical compression
heat pump is fully used for inputting mechanical work, and a heat source does not need to be additionally arranged, so that the adaptability and economical efficiency of the
seawater desalination system are improved, and the
seawater desalination system meets the national targets of
energy conservation, emission reduction and the energy and environment
sustainable development strategy.
