Water circulation system of gas pump station under mine

Abstract

The invention provides a water circulation system of a gas pump station under a mine. The system comprises a first drainage pump and a gas-water separator, which are connected in series, wherein the first drainage pipe is further connected with a water supply pipeline of the mine, the system further comprises a circulating water tank, the water inlet end of the circulating water tank is connected with the water outlet end of the gas-water separator, and the water outlet end is connected with the water supply pipeline of the mine. The embodiment of the invention provides the water circulation system of the gas pump station under the mine, water from the gas-water separator enters into the circulating water tank and further enters into the water supply pipeline of the mine from the circulating water tank so as to effectively utilize the water which is separated in the gas-water separator and save water resources and electrical energy; furthermore, when the water supply pipeline of the mine cuts off the water supply, the water which is separated in the gas-water separator can further ensure the normal operation of the drainage pump and the production efficiency is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mining, and in particular to a water circulation system of an underground gas pumping station in a mine. Background technique [0002] The water circulation system is an important part of the underground gas drainage pumping station, which determines whether the underground gas drainage in the mine is carried out normally. In the existing mine underground gas pumping station system, the external water source is discharged into the gas-water separator through the pumping pump, and then discharged to the bottom water tank through the gas-water separator, and the water in the bottom water tank is discharged to the ground through the water pump . This method makes the water discharged from the gas-water separator unusable, wasting water resources; the water in the bottom water tank must be pumped to the ground, which increases the drainage burden of the mine and wastes electric energy; ...
