Abstract

The invention provides an efficient geothermal heat utilization system and method based on solid heat conduction. The system comprises a heat transfer well, an underground heat collection section, a ground heat exchange device and a solid heat transfer rod, wherein the heat transfer well is arranged in a stratum layer, the upper end of the heat transfer well extends upwards to the ground, the lower end of the heat transfer well extends downwards into a geothermal storage layer, the underground heat collection section is formed in the portion, located in the geothermal storage layer, of the heat transfer well so as to collect geothermal energy in the geothermal storage layer; and the ground heat exchange device is arranged on the ground, the solid heat transfer rod is arranged in the heat transfer well, one end of the solid heat transfer rod is connected with the ground heat exchange device, the other end of the solid heat transfer rod extends downwards to the underground heat collection section, and heat energy in the geothermal energy storage layer collected by the underground heat collection section is conducted into the ground heat exchange device. According to the efficient geothermal heat utilization system based on solid heat conduction and a utilization method thereof, solid medium is used for realizing geothermal transmission, and the core components including a solid heat transfer rod system and a related heat collection and insulation system have the advantages of being efficient, environment-friendly, wide in application range and the like.

Description

technical field [0001] The invention relates to the field of geothermal resource utilization. More specifically, the present invention relates to a high-efficiency geothermal utilization system based on solid heat conduction and a utilization method thereof. Background technique [0002] Geothermal resources are one of the important renewable resources. According to the different temperature range of geothermal utilization, it is mainly divided into two types: one is medium and low temperature geothermal, the temperature range is usually below 150 ℃, and the medium and low temperature geothermal resources are usually distributed in shallow underground or on the surface. One is high-temperature geothermal with a temperature range of 150°C to 360°C. High-temperature geothermal resources are usually distributed in deep underground, such as hot dry rock formations, high-temperature steam, etc. (the depth can reach 5000 meters to 7000 meters, or even deeper). The medium and lo...
