Abstract

The invention relates to a geothermal energy heat exchange device which comprises U-shaped heat exchangers, an output pipe, a power pump, a heat pump heat exchanger, a tail end, a return pipe and a heat storage rock stratum. One or more sets of U-shaped heat exchangers are arranged in the heat storage rock stratum. The U-shaped heat exchangers are filled with circulating media needed by heat exchange. The U-shaped heat exchangers are connected with the output pipe and the return pipe and are connected to the power pump and the heat pump heat exchanger through the output pipe. The heat pump heat exchanger is connected with the tail end. The heat pump heat exchanger is connected to the U-shaped heat exchangers through the return pipe. The temperature of the circulating media in the U-shapedheat exchangers rises in the heat exchangers, energy of the rock stratum and hot water is absorbed, the heat energy is conveyed to the heat pump heat exchanger, and the low-temperature circulating media return to the U-shaped heat exchangers after heat exchange is completed. Reciprocating circulation is carried out, and the heat energy can be developed with low cost, high efficiency and environmental friendliness. The geothermal energy heat exchange device is a novel heat exchange system which improves the geothermal utilization efficiency.

Description

technical field [0001] The invention relates to a combined heat exchange system for deep geothermal exploitation, in particular to a geothermal energy heat exchange device. Background technique [0002] Geothermal energy is natural thermal energy extracted from the earth's crust. This energy comes from the lava inside the earth and exists in the form of heat. It is a renewable energy source. According to official data released by the Ministry of Land and Resources of China, the total amount of hot dry rock resources at a depth of 3,000 meters to 10,000 meters in mainland China is equivalent to 260,000 times the total annual energy consumption in China; geothermal utilization is mainly direct utilization, and the energy directly utilized is the largest The share is ground source heat pump with 49.0%, followed by bathing and swimming with 24.9%, and conventional geothermal heating with 14.4%. There are two main disadvantages in the way of direct exploitation of groundwater: o...
