Geothermal energy high-efficiency heat exchanger

Abstract

The invention relates to a geothermal energy high-efficiency heat exchanger comprising a bearing keel, heat exchange plates, heat exchange pipes, guide pipes, temperature sensors and pressure sensors.The bearing keel comprises locating racks, guide sliding rails, sliding chutes and hoisting rings; the heat exchange plates are embedded in the locating rack, and the heat exchange pipes are installed on the upper and lower surfaces of each heat exchange plate separately; the two ends of each heat exchange pipe communicate with the guide pipes separately, and at least three temperature sensors are provided, wherein at least one temperature sensor is embedded on the outside surface of the heat exchange plate, and the rest temperature sensors are located at the connection positions between thetwo ends of each heat exchange pipe and the guide pipes; at least two pressure sensors are provided, and uniformly distributed on the outside surface of the locating rack around the axis of the locating rack. According to the high-efficiency heat exchanger, on one hand, the working efficiency of geothermal energy resource collection can be improved effectively, and the construction cost of the collection operation is reduced; on the other hand, the structure of geothermal energy resource collection equipment is simplified effectively, and the reliability and stability of the geothermal energyresource collection are improved; and the operation cost is reduced.

Description

technical field [0001] The invention relates to a device for developing and utilizing geothermal energy, in particular to a high-efficiency heat exchange device for geothermal energy. Background technique [0002] At present, in the development and utilization of geothermal energy, it is mainly obtained by directly mining and extracting resources such as hot and high-temperature water, water vapor, and hot dry rock deep in the formation. Although it can meet the needs of geothermal resource collection, in actual It was found in the geothermal energy collection operation that in the current collection method, due to the direct extraction of hot and high-temperature water and water vapor, it is very easy to cause serious pollution to geothermal resources by impurities such as sediment in hot and high-temperature water and water vapor. It even leads to the blockage of geothermal resource collection pipelines, which seriously affects the efficiency and quality of geothermal reso...

[0002] At present, in the development and utilization of geothermal energy, it is mainly obtained by directly mining and extracting resources such as hot and high-temperature water, water vapor, and hot dry rock deep in the formation. Although it can meet the needs of geothermal resource collection, in actual It was found in the geothermal energy collection operation that in the current collection method, due to the direct extraction of hot and high-temperature water and water vapor, it is very easy to cause serious pollution to geothermal resources by impurities such as sediment in hot and high-temperature water and water vapor. It even leads to the blockage of geothermal resource collection pipelines, which seriously affects the efficiency and quality of geothermal resource collection operations. At the same time, it needs to be equipped with a large number of auxiliary equipment such as filtering equipment, which also leads to increased geothermal resource collection costs and daily equipment maintenance costs. At the same time, due to the direct mining of resources such as hot and high-temperature water, water vapor, and hot dry rock, it is very easy to cause hollow areas in the deep underground, resulting in unstable geological structures, poor bearing capacity, and even geological subsidence in severe cases The occurrence of secondary geological disasters, such as secondary geological disasters, has great potential safety hazards and has a great impact on the construction of surface structures such as roads and buildings. Therefore, in view of this situation, it is urgent to develop a new geothermal heat exchange equipment to meet practical needs
