Water-gas separating and treating device

Abstract

The invention provides a water-gas separating and treating device which comprises a closed cylindrical container. A drainage pipe used for inputting water-gas mixtures into the container and a gas outlet pipe used for discharging gas separated from the water-gas mixtures are arranged on the upper surface of the container. The inflowing end of the drainage pipe is connected with the positive pressure side of an extraction pump station, and the outflowing end of the drainage pipe is arranged at the position, close to the lower surface of the container, in the container. The gas inlet end of the gas outlet pipe is arranged on the upper surface of the container, and the gas outlet end of the gas outlet pipe is connected with the negative pressure side of the extraction pump station. A water outlet is further formed in the side wall of the container. According to the water-gas separating and treating device, water is used for submerging the low input end of the water-gas separating and treating device to achieve the water sealing effect. On one hand, water and gas are guided in through the function of negative pressure drainage, and the water and the gas are separated through the water sealing effect. On the other hand, the gas is drawn into an extraction system through the negative pressure drainage, and water-gas separation is effectively achieved.

Description

technical field [0001] The invention relates to the technology of discharging water on the positive pressure side of a pumping station, in particular to a water-gas separation treatment device. Background technique [0002] The explosion-proof and flashback-proof device on the positive pressure side of the mine drainage pumping station is not completely separated from water and gas, which may easily cause safety hazards such as increased pump load and pump holding, which has a serious adverse effect on the management of the mine gas drainage system. At the same time, part of the gas enters the hot water pool with the water, causing a large amount of gas to accumulate on the water surface, which brings major safety hazards and hazards to the safety management of the pumping station. However, in the prior art, manual intermittent water discharge cannot eliminate hidden dangers in time. Contents of the invention [0003] Aiming at the defects of the prior art, the present inv...

Problems solved by technology

[0002] The explosion-proof and flashback-proof device on the positive pressure side of the mine drainage pumping station is not completely separated from water and gas, which may easily cause safety hazards such as increased load on the pump and suffocation of the pump, which will have a serious adverse effect on the management of the mine gas drainage system.

At the same time, part of the gas enters the hot water pool with the water, causing a large amount of gas to accumulate on the water surface, which brings major safety hazards and hazards to the safety management of the pumping station. However, in the prior art, manual intermittent water discharge cannot eliminate hidden dangers in time.
