Geothermal energy hot dry rock heat exchange device monitoring system and heat exchange monitoring method thereof

Abstract

The invention discloses a geothermal energy hot dry rock heat exchange device monitoring system and a heat exchange monitoring method thereof, and belongs to the technical field of clean energy. The technical problems that the geothermal energy hot dry rock heat extracting efficiency is low and the underground heat exchange fluid wastage rate is high are solved, and the geothermal energy extracting process can be monitored in real time. According to the technical scheme, a data acquisition system is arranged in a heat exchange system and transmits acquired data to a data processing module through a data transmission system; the signal output end of the data processing module is electrically connected with a display module and a control module; and a heat exchange medium carrying high-temperature geothermal energy is finally obtained through the steps that the heat exchange system is prepared as well as the data acquisition system and the data transmission system being packaged, geothermal energy detection and drilling are performed, heat exchange medium filling and extracting are controlled, and geothermal energy exchange and monitoring are performed. A heat exchange tube is resistant to heat and corrosion and long in service life; the heat exchange efficiency is improved while waste of heat exchange medium resources is reduced; and whole-course monitoring and automatic control over the heat exchange medium heat exchange and extracting process are achieved.

Description

technical field [0001] The invention belongs to the technical field of clean energy, and in particular relates to a monitoring system for a geothermal dry hot rock heat exchange device and a heat exchange monitoring method thereof. Background technique [0002] Compared with other new energy sources such as solar energy, wind energy and biomass energy, geothermal resources have the characteristics of wide distribution and little external influence such as day and night, wind speed, temperature difference, carbon emissions and low maintenance costs. Geothermal resources are mainly divided into hydrothermal Hot dry rock type geothermal heat refers to the heat stored in high-temperature rock mass or magma at a depth of 3-10km, and the reservoir temperature can reach 100-650°C. At present, the hydrothermal type medium and low temperature geothermal mainly used by countries in the world only accounts for a very small part of the proven geothermal resources, while the medium and h...
