Geothermal power generation device

Abstract

Disclosed is a geothermal power generation device. The geothermal power generation device comprises a heat exchanger and a circulating sealed heat conducting pipe, wherein the heat exchanger is installed inside a geothermal well, and the circulating sealed heat conducting pipe is arranged inside the heat exchanger and penetrates out of the heat exchanger. A heat conducting medium is installed inside the heat conducting pipe. The portion, penetrating out of the heat exchanger, of the heat conducting pipe is arranged on the surface of a hot end of a temperature difference generator. A flow gauge and a circulating pump are arranged on the section, arranged outside the heat exchanger and connected with the temperature difference generator, of the heat conducting pipe. The circulating pump is connected with an output end of a controller. An input end of the controller is connected with a temperature sensor arranged inside the heat exchanger. A cold end of the temperature difference generator is provided with a cold water pipe. One end of the cold water pipe is connected with a water injection port of the cold water pipe. A condenser and a cold water valve are installed between the cold water pipe and the water injection port of the cold water pipe. The temperature difference generator is connected with a storage cell. The geothermal power generation device is simple in structure, stable in operation, capable of continuously generating electric energy, free of environmental hazards, free of the requirement for discharging water out of the geothermal well, free of the requirement for large-scale devices like a steam turbine, and high in environmental benefit.

Description

technical field [0001] The invention provides a geothermal power generation device, which is used for converting geothermal energy into electric energy, and is especially suitable for small-scale geothermal power generation occasions without pollution. Background technique [0002] The earth's own thermal energy is an inexhaustible, cheap and environmentally friendly energy source for human beings. Geothermal technologies have been developed and referenced, such as geothermal power generation, geothermal heating, and geothermal heat source pumps. Geothermal energy has its unique advantages. First, geothermal energy is 100% controllable; second, geothermal energy reserves are sufficient; third, geothermal energy is taken from the ground and has little environmental pollution. Due to the above advantages, the utilization of geothermal energy has developed very rapidly, and has been widely used in various aspects such as industrial processing, civil heating, bathing, etc., and ...

AI Technical Summary

Problems solved by technology

Geothermal water contains a large amount of toxic minerals, direct discharge of geothermal water will have a bad impact on the environment, and the use of recharge technology will pose a threat and pollution to groundwater sources, and the requirements are complex and costly, which restricts the wide application of geothermal technology and development

There are also many chemical substances contained in the geothermal fluid, which have different effects on the metal surfaces and directly affect the service life of the equipment.
