A device for mining hot dry rock geothermal resources

Abstract

The invention provides a device for mining hot dry rock geothermal resources, which belongs to the field of energy mining equipment and includes an input pipeline, a heat exchange module, an output pipeline and a heat exchange module; the heat exchange module includes a plurality of heat exchange units, and a plurality of heat exchange units The units are set on the output pipeline and arranged evenly along the height direction of the output pipeline, and the input pipeline is set on one side of the output pipeline; each heat exchange unit is provided with an inlet and an outlet, the inlet is connected with the input pipeline, and the outlet is connected with the output pipeline; The heat exchange module includes a heat exchange terminal and a medium terminal, the heat exchange terminal communicates with the medium terminal, the upper end of the input pipeline communicates with the medium terminal through the heat exchange pump, and the upper end of the output pipeline communicates with the heat exchange terminal through the heat exchange pipeline. The device achieves layered collection by setting multiple heat exchange units, which solves the problem of high heat energy being blocked in deep layers, greatly increases the contact time between the heat exchange medium and the dry hot rock mass, reduces the speed of heat energy attenuation, and thus improves the heat exchange rate. Thermal efficiency.

Description

technical field [0001] The invention belongs to the field of energy mining equipment, in particular to a device for mining hot dry rock geothermal resources. Background technique [0002] Geothermal energy is one of the promising renewable energy sources. Compared with other new energy sources such as solar energy, wind energy and biomass energy, it has the advantages of wide distribution, large reserves, renewable, clean application, and little external influence (such as day and night). , wind speed, temperature difference) and other characteristics, so it has received attention in the field of energy development. With the vigorous improvement and development of science and technology and geological exploration and development technology, the geothermal resources in the deep bottom of the reservoir are more and more concerned by energy developers. Hot dry rock geothermal resources have become an important field for future geothermal energy development because they are not...

AI Technical Summary

Problems solved by technology

[0004] Although this tubular transmission tool can achieve the purpose of geothermal resource exploitation, due to the high underground pressure, the steam resistance is increased, the collection energy consumption is large, and the heating area of ​​the tubular tool is limited, which reduces the heat exchange rate
