Geothermal continuous heat exchanging pipeline and heat exchanging system

Abstract

The invention discloses a geothermal continuous thermal exchanging pipeline and a thermal exchanging system. The geothermal continuous thermal exchanging pipeline comprises an external protective pipeand an injection pipe arranged together in a sleeving manner; multiple thermal exchanging output pipes are arranged in a sandwich layer between the external protective pipe and the injection pipe; reserved gaps formed among the external protective pipe, the injection pipe and the multiple thermal exchanging output pipes are filled with thermal insulation materials; and the bottom ends of the multiple thermal exchanging output pipes all communicate with the bottom end of the injection pipe. According to the geothermal continuous thermal exchanging pipeline, as the injection pipe used for conveying cold water and the thermal exchanging output pipes used for exchanging thermal and conveying hot water are uniformly centralized in the external protective pipe, a traditional double pipe thermalexchanging mode is simplified so that the number of pipelines in a geothermal well is reduced, and the casing installation difficulty during geothermal exploitation is reduced; and meanwhile, multiple data wire pipelines are also arranged in the sandwich layer between the external protective pipe and the injection pipe, the geothermal continuous thermal exchanging pipeline has double functions ofthermal exchanging and data transmission.

Description

technical field [0001] The invention relates to the field of geothermal exploitation, in particular to a geothermal continuous heat exchange pipeline and a heat exchange system. Background technique [0002] With the increasing demand for resources in the world, the demand for energy such as oil and coal, which dominate energy consumption, is also gradually increasing, and the contradiction between supply and demand is becoming increasingly tense. At the same time, the problem of environmental pollution caused by traditional energy is becoming more and more serious, and energy conservation and emission reduction have gradually become the main problem. Geothermal energy is one of the renewable energy sources with great prospects. Compared with other new energy sources such as solar energy, wind energy and biomass energy, geothermal energy has the characteristics of wide distribution, little influence from external factors, low carbon emissions and maintenance costs. . At pr...
