Power generation device utilizing geothermal temperature difference

Abstract

The invention relates to the field of clean energy application, and discloses a power generation device utilizing geothermal temperature difference. The power generation device comprises a heat exchange device; the upper end of the heat exchange device is connected with a hot gas pipeline; the upper end of the hot gas pipeline is connected with a geothermal steam turbine; the upper end of the geothermal steam turbine is connected with a geothermal generator; the right end of the geothermal steam turbine is connected with a condenser; the right end of the condenser is connected with a liquid return pipe; and a thermoelectric power generation device is arranged between the hot gas pipeline and the liquid return pipe. Through increasing internal heat of the heat exchange device, ammonium chloride liquid inside a heat absorption material is heated and rapidly decomposed to increase gas volume; the gas is transmitted to the geothermal steam turbine through the hot gas pipeline to push the geothermal generator to generate electricity; the condenser is used for cooling and liquidation according to the chemical reaction: NH+HCI=NHCI; and the liquid NHCI and the water return to the heat exchange device through their gravity to achieve a circulation effect. The integral structure can achieve power generation underground, and can solve the problems of high cost and inconvenient maintenance.

Description

technical field [0001] The invention relates to the technical field of clean energy application, in particular to a power generation device utilizing geothermal temperature difference. Background technique [0002] Geothermal energy is the natural heat energy extracted from the earth's crust, and a large amount of heat energy is stored in the lava inside the earth. Geothermal energy is a cheap and inexhaustible new clean energy. We need this widely used clean energy very much, because in the case of increasingly scarce energy, the rational development of geothermal resources is becoming more and more important. Such as the use of geothermal water for house heating, the development of greenhouse agricultural planting and hot spring tourism and so on. [0003] At present, there are many devices on the market that use geothermal temperature difference to generate electricity. Among them, the flash system uses high-pressure hot water to pump hot water from a hot water well to t...
