Loop type heat pipe exploitation middle-shallow layer hydrothermal type geothermal system

Abstract

The invention discloses a loop type heat pipe exploitation middle-shallow layer hydrothermal type geothermal system which comprises a loop type heat pipe, a heat utilization device and a middle-shallow layer groundwater hypertonicity geothermal reservoir. The loop type heat pipe is provided with a loop type heat pipe evaporation section, a loop type heat pipe heat insulation section, a loop type heat pipe condenser and a loop type heat pipe fluid pipeline section which are located in the hypertonicity geothermal reservoir; the loop type heat pipe heat insulation section comprises a steam pipeline section and a heat insulation material layer for tightly wrapping the outer wall of the steam pipeline section; and one end of the loop type heat pipe evaporation section is communicated with one end of the loop type heat pipe fluid pipeline section, the other end of the loop type heat pipe fluid pipeline section is communicated with one end of the steam pipeline section through the heat release side of a heat exchanger, and the other end of the steam pipeline section is communicated with the other end of the loop type heat pipe evaporation section. By means of the loop type heat pipe exploitation middle-shallow layer hydrothermal type geothermal system, the problem about self starting of the overall geothermy exploitation system can be solved; and meanwhile, the heat long-distance transportation can be achieved, the problem of conflicts of steam flow and liquid flow of a tradition heat pipe is solved, and the heat transferring efficiency is greatly improved.

Description

technical field [0001] The invention relates to a mid-shallow hydrothermal type geothermal heating system, in particular to a loop-type heat pipe exploitation mid-shallow hydrothermal geothermal system. Background technique [0002] As a clean and renewable energy source, the efficient utilization of geothermal resources is crucial to my country's energy conservation and emission reduction work. my country's medium and shallow geothermal resources are relatively rich, which can meet the heating needs of a large number of buildings, effectively alleviate the smog and other mitigation problems caused by coal heating, and have great potential for development and utilization. The formation process of mid-shallow hydrothermal geothermal is usually that atmospheric precipitation or surface water seeps into the ground, absorbs heat from the flowing groundwater, and stores it underground in the form of high-temperature hot water or steam, forming a geothermal heat system.
