The invention is applicable to the technical field of geothermal utilization, and provides a geothermal recharge system and a thrust valve. The geothermal recharge system includes recharge wells, return pumps, filter and emptying units, delivery pipes and impact valves. In the geothermal recharge system provided by the present invention, the thrust valve is arranged between the lift pump and the delivery pipeline in the flow direction of the refill water, and the lift valve is connected to the lift pump and the delivery pipeline during the lift operation; During the recharging operation, the impulse valve cuts off the connection between the return pump and the conveying pipeline, and discharges the recharge water in the conveying pipe to the recharge well, thereby reducing the flow of recharge water into the return pump during the recharge process, thereby reducing the impact of the return pump. damage, realize the use of the same pipeline as the hoisting function and the recharge function, and reduce the cost of geothermal water recharge.
Description
technical field [0001] The invention belongs to the technical field of geothermal utilization, and more specifically relates to a geothermal recharge system and a thrust valve. Background technique [0002] In recent years, geothermal energy has been actively developed and utilized as a clean energy source. Geothermal well technology has developed rapidly. People extract hot water from geothermal wells for heating, bathing, swimming pool heating, and power generation. For the tail water after utilization, some geothermal well users directly discharge it into the trench, which wastes water resources and pollutes the environment. There are also some users who set up backwater wells and use the method of recharging the same layer to recharge the used tail water underground. This kind of recharging method is not stable. The recharging wells used in the initial stage are less difficult to recharge, but it still needs to be recharged. The method of raising back is often used to s...
