Abstract

The invention provides a geothermal energy-driving heat recovery system which comprises a geothermal energy exploitation well, a desander, a flowmeter, a absorption heat pump, heating equipment, a geothermal energy recharge well and recharge treatment facilities, and further comprises a first heat exchanger, a second heat exchanger, a first circulating pump, a second circulating pump, a pressure gauge and a thermometer, wherein valves are respectively arranged at the two ends of the first circulating pump and the second circulating pump; and a temperature transmitter and a pressure transmitter are arranged at the outlet end of the geothermal energy exploitation well. The heat recovery system has the benefits that the heat of the used geothermal water with reduced temperature can be further utilized so as to greatly improve the utilization rate of the geothermal energy, and meanwhile, other energy is not consumed. Therefore, the heat recovery system has a more realistic significance for areas with abundant geothermal energy.

Description

technical field [0001] The invention belongs to the application field of geothermal heating, in particular to a geothermal self-driven heat recovery system. Background technique [0002] In the existing geothermal resource utilization technology, the outlet water temperature of some commonly used geothermal wells can be as high as 95°C or even higher, and when used for building heating, the water supply temperature of 45°C can meet the requirements. The usual practice is to convert the 95°C geothermal water into 45°C heating water for heating, and the lower temperature geothermal water can be used in steps or adjusted to a slightly lower temperature as the heat source of the compression heat pump to further reduce own temperature, and then recharge. The above-mentioned process needs to consume other energy sources, and the utilization of geothermal heat is not sufficient. Contents of the invention [0003] The problem to be solved by the present invention is to provide a...
