Problems solved by technology

Geothermal water contains a large amount of toxic minerals. Direct discharge of geothermal water will have a bad impact on the environment, and geothermal resources are limited. If unrestricted use, not only the geothermal resources may be exhausted, but also the groundwater level will drop , for this reason, the recharge of geothermal water is very necessary

Embodiment Construction

[0008] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0009] The system comprises a suction pipe 1, a recharge pipe 2, a water baffle 4 and a submersible pump 6. There is a return pipe 2 next to it;

[0010] The geothermal water enters the suction pipe 1 through the pressure of the submersible pump 6, and then flows into the upper part of the geothermal well through the recharge pipe 2 after being used by the ground utilization system. When the water level in the lower pumping area drops, the recharge water will pass through the water baffle 4 Controlled flow into the pumping area to replenish geothermal water and realize the recycling of geothermal water.

[0011] The geothermal well is sealed so that the geothermal well is in a vacuum state to avoid the entry of air.

[0012] Many other changes and modifications can be made without departing from the spirit and scope of the present invention. It shoul...

Abstract

A recharge device for underground water energy utilization is characterized by comprising a pumping pipe, a recharge pipe, a water-stop sheet and a submersible pump. The lower end of the pumping pipe is connected with the submersible pump, the upper end of the submersible pump is provided with the water-stop sheet, the recharge pipe is arranged beside the pumping pipe, and geothermal water enters the pumping pipe through pressure of the submersible pump and then flows back to the upper portion of a geothermal well through the recharge pipe after being used by a ground utilization system. When a water level of a pumping area on the lower portion drops, recharge water flows into the pumping area through control of the water-stop sheet to complement the geothermal water, and accordingly circulating utilization of the geothermal water is achieved. The recharge device is simple, efficient and capable of solving recharge problems.

Description

technical field [0001] The invention relates to the technical field of geothermal utilization, in particular to a recharge device for groundwater energy utilization. Background technique [0002] The earth's own thermal energy is an inexhaustible, cheap and environmentally friendly energy source for human beings. Geothermal technologies have been developed and referenced, such as geothermal power generation, geothermal heating, and geothermal heat source pumps. Geothermal energy has its unique advantages. First, geothermal energy is 100% controllable; second, geothermal energy reserves are sufficient; third, geothermal energy is taken from the ground, which has little environmental pollution. Due to the above advantages, the utilization of geothermal energy has developed very rapidly, and has been widely used in various aspects such as industrial processing, civil heating, bathing, etc., and has received good economic and technical benefits and saved energy. With the wide a...
