Problems solved by technology

[0004] In the current geothermal well system design, water intake pumps with recharge function are mostly used. During the operation of geothermal well groups, if some geothermal wells decrease in recharge due to blockage or other reasons, the system pump will be added. consumption, which will ultimately affect the operation stability of the entire geothermal well group system

Abstract

The invention provides a geothermal well group intelligent recharge control system and method. The geothermal well group intelligent recharge control system comprises a plurality of geothermal wells,a water collector, a plate heat exchanger, a water segregator and a heat pump host machine, wherein each geothermal well is internally provided with a water intake pump; the water outlet ends of the plurality of water intake pumps are respectively communicated with the water inlet end of the water collector through pipelines; the water outlet end of the water collector is communicated with the water inlet end of the water segregator through the plate heat exchanger; the plate heat exchanger is connected with the heat pump host machine; a plurality of recharge pumps are arranged at the water outlet end of the water segregator; the recharge pumps are in one-to-one correspondence with the geothermal wells; a balance pipe is arranged between the water segregator and the water collector; the water outlet end of each recharge pump is communicated with the corresponding geothermal well through a pipeline; a first flow meter and a conductivity meter are arranged at the water outlet end of eachwater intake pump; a pressure gauge and a second flow meter are arranged at the water outlet end of each recharge pump; and a third flow meter is arranged on the balance pipe.

Description

technical field [0001] The invention belongs to the technical field of geothermal energy utilization in a ground source heat pump system, and in particular relates to an intelligent recharge control system and method for a geothermal well group. Background technique [0002] As the largest developing country in the world, China is facing a series of problems, such as environmental pollution, resource shortage and climate change, while its economy is developing rapidly. Among them, the shortage of resources is particularly prominent. [0003] The ground source heat pump system is the transfer of geothermal energy from low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy). Geothermal energy is a non-polluting, renewable and clean energy. Rivers, lakes and seas belong to the category of shallow geothermal energy. Advantages such as land access. The development and utilization of geothermal energy belongs to...
