Embodiment Construction

[0016] The groundwater raw water sustainable pumping and irrigation system of the present invention will be described in detail in conjunction with accompanying drawing 1 .

[0017] Accompanying drawing 1 shows the groundwater raw water sustainable pumping and irrigation system, this system is made up of pumping well (1), recharge well (2), deep well submersible pump (3) and groundwater pipeline (4) etc., groundwater pipeline ( 4) Including the heat exchanger (5), solenoid valve (6), exhaust valve (7, 8, 9), well chamber (10, 11) and cut-off check valve (12) in the ground energy system. The deep well submersible pump (3) refills the underground hot water extracted from the pumping well to the refilling well after passing through the groundwater pipeline for heat exchange. From the pumping well to the reinjection well, the entire groundwater system maintains a sealed positive pressure state and is completely isolated from the outside air. The recharge of groundwater is continu...

Abstract

Disclosed is a fully-sealed underground raw water continuous pumping and injecting system. The system comprises a pumping well (1), a reinjection well (2), a deep well submersible pump (3) and an underground water pipeline (4), wherein underground water pumped from the pumping well (1) is reinjected into the reinjection well (2) by the deep well submersible pump through the underground water pipeline (4). The system is characterized in that the underground water of the system is completely isolated from the earth surface, underground raw water can be continuously and efficiently reinjected without water treating equipment like a cyclone desander or a filter, and all the underground raw water can be reinjected.

Description

technical field [0001] The invention relates to many fields related to groundwater, such as groundwater pumping and irrigation in a geothermal energy system, groundwater recharge in foundation pit dewatering, and the like. The recharge of groundwater is the need to protect groundwater resources and maintain the stability of groundwater level, so as to protect the underground hydrogeological environment and avoid geological disasters such as land subsidence and ground subsidence. Background technique [0002] Geothermal energy application systems, such as aquifer energy storage, groundwater source heat pumps, geothermal air conditioning, and deep geothermal energy, utilize renewable and clean energy. Due to its high energy efficiency, it can replace traditional fossil fuels and has been widely recognized by the energy industry. At present, the smog caused by the traditional coal-fired heating in winter in China has caused serious environmental problems, while other clean ene...
