GEOTHERMAL POWER PLANT Russian patent published in 2022 - IPC F03G4/00 F03G7/04 

FIELD: power industry.

SUBSTANCE: invention relates to a geothermal power plant. The power plant includes an injection well 2 and is equipped with a compressor 25 installed after the cooler 9 in front of the condenser 26, made with the possibility of transferring heat to the network coolant 27, a network pump 22 that circulates the coolant 27 to transfer heat from the refrigerant and the separated liquid 14 to the heat consumer unit 20, a heat exchanger 30 that provides heat transfer from the separated liquid 14 to the coolant 27 for use in the unit 20, a degassing unit 21 for removing non-condensable gases from water vapor condensed in the evaporator 15 and cooled in the heat exchanger 30, a sludge separator 16 installed in front of the separator 13, providing the release of suspensions from the geothermal fluid and eliminating heat losses from the separated liquid 14 discharged into the well 2, and when cooling the refrigerant 23 in a binary cycle, a throttle 28 installed after the condenser 26, using the heat of heating the refrigerant of the heat pump cycle 18 by cooling the refrigerant 23, and control valves 29. The pump 2 is designed with the possibility of pumping the cooled separated liquid 14 and concentrated water vapor into the well 2.

EFFECT: invention is aimed at ensuring the effective use of the heat of the separator and heat during air cooling of the refrigerant.
