GEOTHERMAL INSTALLATION FOR POWER SUPPLY TO CONSUMERS Russian patent published in 2024 - IPC F24T10/20 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering, namely to autonomous electric and heat supply installations using geothermal energy of the Earth and can be used for power supply with electric and thermal energy. Geothermal power supply unit for consumers contains the first pump installed in the well, the output of which is connected by a pipeline to a filter for cleaning geothermal water from rock and salt impurities. Evaporator is connected to economizer, output of which is connected to input of second pump, which is connected through fine filter to pipeline, end of which is intended for immersion into injection well. Outlet of the second pump is connected through the first gate to the first inlet of the heater of the heat supply circuit, the first outlet of which is connected through the second gate to the inlet of the fine filter. Evaporator is connected by pipeline to turbine, which is connected to electric generator. Turbine outlet is connected to the regenerative heater, the outlets of which are connected by pipelines to the economizer and to the air-cooled condenser. Output of the third pump is connected to the second input of the regenerative heater. Second heater output of heat supply circuit serves to transfer heated water to heat energy consumer. Inlet of the fourth pump is designed to receive cooled water from the heat energy consumer, and the outlet of the fourth pump is connected to the second inlet of the heat supply circuit heater. Outlet of the filter for cleaning geothermal water from rock and salt impurities is connected by a pipeline to a degasser, the first outlet of which is connected by a pipeline to a gas dryer, which is connected to a gas boiler, to which the second outlet of the degasser is connected. Outlet of the gas boiler is connected to the evaporator, and the outlet of the air-cooled condenser is connected to the coolant accumulator tank, the outlet of which is connected to the inlet of the third pump.

EFFECT: improving reliability and efficiency of a geothermal installation.
