Geothermal well tail water recharges system's device

The utility model provides a geothermal well tail water recharges system's device, includes desander, vapour and liquid separator, coarse filter group, fine filter group, pressurizes and recharge the pump, desander and vapour and liquid separator pass through pipeline connection, vapour and liquid separator and pressurization recharge the pump and pass through pipeline connection, and install coarse filter group and fine filter group in proper order on vapour and liquid separator recharges the pipeline between the pump with the pressurization, pressurize and recharge the pump and pass through the pipeline connection recharging well, its advantage is: this system can thoroughly clear away the silt in the tail water, prevents that the recharging well from blockking up, and the high pressure recharges has guaranteed that long -term effectual whole tail water recharge, realizes that geothermal resource does not fetch water, does not only get heat, recycles, guarantees geothermal resource's sustainable use.
