Problems solved by technology
[0002] Most of the existing driving devices that use geothermal energy to generate electricity are to guide geothermal heat to the ground through wells. The wells must be drilled to a sufficient depth to use the heat in the earth's crust to evaporate water or other liquids to obtain steam. Drive the steam turbine to do work to generate electricity, but because the steam will lose a lot of heat when it is sent to the ground, and the temperature will gradually decrease during the transmission process, so a large amount of steam must be sent to the ground to generate enough electricity. As a result, the heat transfer efficiency is low, and the scope of application of the geothermal power generation system is small, which restricts the development of geothermal energy technology

The invention discloses a power generation system utilizing terrestrial heat energy and belongs to the technical field of development and utilization of terrestrial heat energy sources. Through the power generation system formed by connecting a cooling tower, a storage pot, a pipeline pump, a check valve, a heat exchanger, a pressure stored pot, a pneumatic motor or a turbine and a power generator through communicating pipelines, the dynamic pressure generated through gasifying and expanding of liquid with the lower boiling point being lower the water boiling point (100 DEG C) at the normal temperature and in an evaporator drives power generator to operate to generate power through the pneumatic motor or the turbine. Compared with the prior art, the problem of heat energy loss existing in regular underground water source team extraction is solved.
Description
technical field [0001] The invention discloses a power generation system utilizing geothermal energy, which belongs to the technical field of geothermal energy development and utilization. Background technique [0002] Existing driving devices using geothermal energy to generate electricity mostly guide geothermal heat to the ground through wells, and the wells should be drilled to a sufficient depth so that the heat in the earth's crust can be used to vaporize water or other liquids to obtain steam, and the steam can then be regenerated. Push the steam turbine to do work to generate electricity, but because the steam is sent to the ground, a large part of the heat is lost, and the temperature is gradually reduced during the transmission process, so a large amount of steam must be transported to the ground to generate enough electricity. As a result As a result, the heat transfer efficiency is low, and the application scope of the geothermal power generation system is small,...
