Geotherm utilization system based on earth surface water source and hot spring tail water

Abstract

The invention belongs to the field of geotherm utilization and provides a geotherm utilization system based on the earth surface water source and hot spring tail water. The earth surface water or the hot spring tail water is stored in heat source wells, and each heat source well is provided with a heat exchanger used for collecting thermal energy of the earth surface water and the hot spring tail water. An earth surface pipeline buried below the ground is provided with square spiral sections, the distance from the earth surface pipeline to the ground ranges from 1 meter to 5 meters, the projection amount is small, the occupied area is small, the defect that a horizontal buried pipe in the prior art occupies large area is overcome, and the problems that for a vertical buried pipe, a pipeline needs to be buried in the depth tens of meters away from the ground, and the projection amount is large are solved.

Description

technical field [0001] The invention relates to the field of geothermal utilization, in particular to a geothermal utilization system based on surface water sources and hot spring tail water. Background technique [0002] Surface water source refers to the amount of fresh water that can be renewed year by year. It is an important part of water resources, including ice and snow water, river water, lake water, etc. The amount is usually expressed by the restored natural river runoff. Because there is a certain relationship between surface water and groundwater, the part of groundwater that feeds rivers must be deducted in water resource assessment. However, the current geothermal system has not been applied to the surface water source, so that the thermal energy of the surface water source has not been utilized. [0003] Hot springs are natural water that gushes out of the ground. The temperature at the mouth of the spring is significantly higher than the local average annual...

Problems solved by technology

Hot spring tail water refers to the water after hot spring use. Hot spring tail water usually has some recyclable heat energy, but the existing hot spring tail water is usually drained directly. The heat energy in hot spring tail water has not been rationally utilized, resulting in energy waste of
