Deep geothermal energy hot-dry-rock direct supply type heating device

Abstract

The invention discloses a deep geothermal energy hot-dry-rock direct supply type heating device, comprising a heat-insulating water collection tank, a computer control panel, circulating pumps and an output pipe. The water collecting tank is filled with water, one end of the water collection tank is connected to the circulating pumps through first heating pipes, the circulating pumps extend to deep hot-dry-rock blocks through pipes, and the other end of the heat-insulating water collection tank communicates to a user unit through second heating pipes; the computer control panel is arranged on the second heating pipes and is connected to the circulating pumps; the user unit is connected to a second output pipe through the output pipe, and the second output pipe extends to deep hot-dry-rock blocks; and the heat-insulating water collection tank is connected to a water replenishing pipe which is connected to a water replenishing system. More than one circulating pump is arranged. The device does not require ground secondary heat exchange and secondary heating, and deep geothermal energy is directly supplied to the user. The temperature is controlled by adjusting the flow rate of the circulating pumps, the structure is simple, and the heating efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of geothermal heating, in particular to a deep geothermal energy dry hot rock direct-supply heating device. Background technique [0002] Hot dry rock is a kind of hot rock without water or steam, mainly various metamorphic rocks or crystalline rocks, buried at a depth of 2 to 6 kilometers from the surface, and its temperature range is very wide, between 150 and 350 between ℃. The thermal energy of hot dry rocks is stored in rocks, and the more common rocks are biotite gneiss, granite, granodiorite and so on. Generally, hot dry rocks are covered with thermal insulation layers such as sedimentary rocks. Hot dry rock is a geothermal resource. Theoretically, as the earth heats up to the deep, hot dry rocks can be developed in any area reaching a certain depth, so hot dry rocks are also known as ubiquitous resources. Due to its uniquely high temperature, hot dry rock will be a good heat source for heating in...

AI Technical Summary

Problems solved by technology

The current deep geothermal energy dry hot rock heating system mostly adopts underground heat exchange and secondary heat exchange in the ground unit room. Due to the large number of heat exchanges, many links, many paths, many control equipment, the process is relatively complicated, resulting in a large heat dissipation area. , heat loss is large, heat transfer efficiency is low, and the ideal temperature is often not reached, and even secondary heating is required

In this way, there are large equipment rooms, a large number of equipment, many management links, difficult management, and more investment
