Gas separating device and gas separating method

Abstract

The invention provides a gas separating device which comprises a separating box, an automatic water draining device and a manual water draining device. The separating box is provided with an air inlet pipe which is used for gas which is to be separated and is mixed with water to enter. An air discharging pipe which is used for separated gas to be discharged is arranged on the upper portion of the separating box. The manual water draining device and the automatic water draining device are respectively connected to the bottom of the separating box. A gas recycling pipe used for recycling gas is connected between the automatic water draining device and the separating box. The invention further provides a gas separating method. Gas and water are separated at the source, gas separating effect is improved, and construction quality and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water and gas separation in mine mining, in particular to a gas separation device and a gas separation method. Background technique [0002] Gas drainage is the root cause of comprehensive management of mine gas in high gas mines and coal and gas outburst mines. There are many methods of gas drainage, which can be divided into coal seam drainage, adjacent layer drainage, and goaf drainage according to space; According to the time, it can be divided into pre-mining extraction, extraction while digging, extraction while mining, and gob drainage; according to the extraction process, it can be divided into roadway drainage method, drilling drainage method, combined drainage method of roadway and drilling According to whether it is affected by pressure relief, it can be divided into non-pressure relief pumping, pressure relief pumping, etc. However, in the process of mine gas drainage, due to the complicated ...

AI Technical Summary

Problems solved by technology

In the case of high negative pressure, water and gas are mixed together and move forward, and it is difficult to separate. The amount of water entering the storage tank of the automatic water release device is very small, and the water storage tank of the automatic water release device cannot effectively store water. naturally not good

Moreover, the water outlet of the automatic water release device is easily blocked by coal dust, causing unfavorable water discharge.

The above-mentioned automatic water release device and manual water release device have not separated water and gas from the source, and the effect of separating gas is not good
