Heat recovery device of waste water source heat pump high-temperature hot-water unit

The utility model relates to a heat recovery device of a waste water source heat pump high-temperature hot-water unit, which comprises a water source heat pump high-temperature hot-water unit (1), a plate type heat exchanger (2) which is connected to the water source heat pump high-temperature hot-water unit (1) through a circulation water tank (3), a first time heat transfer system connected to the plate type heat exchanger (2), a second time heat transfer system connected to the water source heat pump high-temperature hot-water unit (1) and a hot water output system connected to the second time heat transfer system. The plate type heat exchanger (2) is further connected to the water source heat pump high-temperature hot-water unit (1) through a heat exchange circulating pump (4). Therefore, the heat recovery device of the waste water source heat pump high-temperature hot-water unit has the advantages of being reasonable in design, simple in structure, smaller in noises and very practical, fully recovering heat in waste water, greatly saving consumption of energy sources, discharging no waste smoke or waste gas, and protecting the environment.
