Description
Technical field
The utility model relates to a kind of geothermal well negative pressure recharge vacuum wellhead assemblies, belong to geothermal well equipment technical field.
Background technique
Geothermal energy is the reproducibility thermal energy from earth depths, it arises from the melting magma and radioactive substance of the earth
Decay.After the depths circulation of underground water and the igneous invasion to the earth's crust from profound place, heat is brought from deep under ground to nearly table
Layer.For the operation for guaranteeing water source long-term safety, stable underground water source is needed to supply, it is therefore desirable to which geothermal tail water injects underground
In water-bearing layer, i.e., so-called groundwater artificial recharge (recharge).Water level can be adjusted with recharge of groundwater source by doing so, and maintain storage
Amount balance, can provide Cooling and Heat Source with recharge energy storage；Water-bearing layer head pressure can be kept, surface subsidence is prevented.
General geothermal well directly adopt suction pump and will use after water extraction, long-time use in this way often results in mud
Husky, impurity obstruction suction pump influences production.
