Problems solved by technology

[0003] Traditional geothermal power generation needs to convert thermal energy into mechanical energy and then into electrical energy. The secondary conversion of energy results in underutilization of power generation efficiency and huge waste of resources. It is urgent to find a new technology with high efficiency and low cost to fully develop and Utilize geothermal resources

Embodiment

[0023] Such as figure 1 and figure 2 As shown, the in-situ geothermal thermoelectric power generation device integrated system consists of the outermost layer of cement layer 1 for protection, the middle layer of high thermal conductivity gel layer 3 for heat transfer and protection of thermoelectric device modules, and the innermost layer of cold water circulation tube 4, and a plurality of thermoelectric device modules 2 for thermoelectric power generation are embedded in the high thermal conductivity gel layer 3, and the power generation device with the thermoelectric module 2 as the main body is connected to the ground control device. There is a water flow channel 5 between the layer 3 and the cold water circulation pipe 4. During the power generation operation, cold water flows in from the water inlet 6 and flows out from the water flow channel 5 to form a water circulation system, and adjust the flow of the thermoelectric module 2 by controlling the water flow. tempera...

Abstract

The invention relates to an in-situ geothermal thermoelectric power generation device integrated system, and belongs to the technical field of geothermal power generation. The in-situ geothermal thermoelectric power generation device integrated system is formed by a protective layer in the outermost layer, a high-thermal-conductivity gel layer arranged in the middle and used for conducting heat, and a cold water circulating pipe in the innermost layer. a plurality of thermoelectric device modules used for thermoelectric power generation are embedded into the high-thermal-conductivity gel layer, the power generation device taking the thermoelectric device modules as the main body is connected with a ground control device, and a water flow channel is left between the high-thermal-conductivity gel layer and the cold water circulating pipe. The thermoelectric device does not have mechanical rotational parts, and can work without noise, and can directly convert heat energy into electric energy without generating mechanical energy loss, and is high in generating efficiency; the selected thermoelectric material is simple in preparation technology, stable in structure, small in size, lightin weight and fast in response speed; the same device can be used by selecting different thermoelectric materials according to different heat sources, and is wide in application scope, and can carryout thermoelectric conversion for power generation on different grades of heat sources such as deep ground and hot springs on the earth's surface.

Description

technical field [0001] The invention belongs to the technical field of geothermal power generation, and in particular relates to an integrated system of an in-situ geothermal thermoelectric power generation device. Background technique [0002] Geothermal energy is a green, low-carbon, recyclable and renewable energy. It has the characteristics of large reserves, wide distribution, cleanness, environmental protection, stability and reliability. It is a feasible and competitive clean energy. Although geothermal power generation has been explored for a long time, as of 2016, 25 countries have used geothermal energy for power generation, but the overall development efficiency is not high. As of the end of 2014, the total installed capacity of geothermal power generation in my country was only 27.28MW, ranking 18th in the world, far from the installed capacity of the world's largest geothermal power generation countries. [0003] Traditional geothermal power generation needs to...
