Terrestrial heat water pumping device utilizing vacuum phase change impurity treatment technology

The utility model discloses a terrestrial heat water pumping device utilizing a vacuum phase change impurity treatment technology, and relates to the technical field of terrestrial heat heating. The system comprises a geothermal well, an evaporator is fixed to the top of the geothermal well, a vacuum pump is installed at one end of the evaporator, a condenser is fixed to one end of the vacuum pump, the vacuum pump is connected with the condenser through a first condenser pipe, a first water pump is fixed to one end of the condenser, and a ground source heat pump unit is installed on one side of the first water pump. Through a series of improvements, the device can be applied to terrestrial heat water with high mineralization degree and easy scaling in the application range; and under the action of the evaporator and the condenser, mixed-state high-temperature water and cold water in the geothermal well are subjected to cold and heat exchange and then flow back into the geothermal wellto be circulated, so that
