Abstract

The invention discloses a gas water separating device under a negative pressure state, comprising a gas water separating cabin, a gas water isolating body and a water storage room; the gas water separating cabin comprises several drilling joints, a separating cabin water outlet and a separating cabin gas outlet; the drilling joints are arranged at the side face of the gas water separating cabin, and the separating cabin water outlet and the separating cabin gas outlet are respectively arranged at both ends of the gas water separating cabin; the water storage room comprises a water storage room water inlet, a water storage room gas ventilating opening and a water storage room draining opening; the gas water separating cabin is connected with a gas extraction drilling hole through a drilling joint, and the gas water isolating body is assembled in the gas water separating cabin; after gas and water enter the gas water separating cabin through the drilling joint, the gas water isolating body guides gas and water to one end of the water outlet of the separating cabin, water enters the water storage room through the separating cabin water outlet and the water storage room water inlet, and gas continues to guide to one end of the separating cabin gas outlet from the gas water isolating body, and enters the gas extraction pipeline from the gas outlet of the separating cabin. The gas water separating device can effectively improve gas water separating degree and improve the extraction efficiency.

Description

technical field [0001] The invention relates to a gas-water separation device under a negative pressure state. Background technique [0002] During the process of gas drainage, the water in the borehole gushes out together with the gas, which directly affects the efficiency of gas drainage. Therefore, it is necessary to separate the gas and water. At present, the usual method of gas-water separation in gas extraction is to allow gas and water to enter a water discharge container at the same time, and the gas is further extracted into the extraction pipeline, while the water in the water discharge container is discharged through a valve. However, due to the low degree of gas-water separation, water is pumped into the pipeline, which still affects the extraction efficiency. [0003] To sum up, there is no gas-water separation method in the prior art that can effectively improve the degree of gas-water separation and further improve the efficiency of gas drainage.
