Single well circulation geothermal energy collection system and collection method of coupling sinking regeneration water plant
The invention discloses a single-well circulation geothermal energy collecting system and method coupled with a sinking type water recycling plant. The system comprises the sinking type water recycling plant, a plurality of single-well circulation underground water source heat pumps around the sinking type water recycling plant, backfill materials, a heat pump unit and a control unit. The sinking type regeneration water plant comprises a sewage treatment unit buried in a backfill material; the single-well circulation underground water source heat pump comprises a well wall, a reinjection area, a partition area and a water pumping area which are sequentially arranged in the well wall, and a backfilling area outside the well wall. The water return pipe is communicated with the water outlet main pipeline and the recharge area, the water pumping pipe is communicated with the water inlet main pipeline and the water pumping area, and a water pump is arranged on the water pumping pipe; a water inlet of the heat pump unit is communicated with the water inlet main pipeline, a water outlet of the heat pump unit is communicated with the water outlet main pipeline, at least one of the water inlet main pipeline and the water outlet main pipeline is provided with a circulating water pump, and circulating water exchanges heat outwards in the heat pump unit; the control unit is in signal connection with the water suction pump, the circulating water pump and the heat pump unit.
