Description

technical field [0001] The invention belongs to the technical field of geothermal power generation, and in particular relates to a thermoelectric generator set using geothermal power generation. Background technique [0002] my country is rich in geothermal resources, but there are only four power stations. This is because the technology of traditional geothermal power generation, especially geothermal power generation in medium and low temperature regions, is very complicated. First of all, a sufficient amount of hot water must be extracted and stored, and the pressure of the container is reduced by reducing the pressure and expanding the capacity, so that the hot water boils and turns into steam, and then drives the steam turbine to generate electricity. Or take the intermediate medium method, because the boiling point of substances such as ethyl chloride or freon is low under normal pressure, use hot water to heat these intermediate mediums to drive steam turbines to gene...
