The invention discloses a medium-deep closed-type geothermal energy heating system, which includes a boiling gas heat exchanger module, which is used to send the heat exchange medium into the ground and guide it to the underground heat exchanger module after heat exchange in the ground Input end: Underground heat exchanger module, used for secondary heat exchange between the heat exchange medium and circulating water after heat exchange, and pumping the circulating water to the single-pipe circulating pipe network, and through the single-pipe circulating pipe network to multiple The single-pipe circulating pipe network will input the return water formed after the multi-level users use the circulating water to the underground heat exchanger module; the generator set is used to connect with the multi-level users in parallel Enter the single-pipe circulation pipe network, pump the underground heat exchanger module into the generator set to separate the heat exchange medium from the circulating water function, and send the separated heat exchange medium to the input end of the boiling gas heat exchanger module. The circulating water produced after separation is sent to the single-pipe circulating pipe network, and the underground indirect multi-media combination heat exchange is used to improve the efficiency of geothermal use and stabilize the water supply of the system.
Description
technical field [0001] The invention relates to the technical field of geothermal energy heating, in particular to a medium-deep closed geothermal energy heating system and a design method thereof. Background technique [0002] The research and development of key technologies for mid-to-deep geothermal energy heating has become a research hotspot in some scientific research institutes in my country. Coupled with the policy support of the state and relevant provinces and cities, the future development prospects are very broad. At present, some commercial buildings and residential buildings in Shaanxi, Hebei, Shanxi, Henan and other places have adopted medium-deep geothermal energy heating technology to achieve winter heating, and this technology is still blank in Yanwei area. Due to the disadvantages of initial investment and adjustment performance, as well as the dependence on geological conditions and the uncertainty of the impact on the surrounding environment, the utiliza...
