Description

Technical Field

[0001] The utility model relates to the technical field of gas delivery pipelines, in particular to a gas water mist delivery pipeline. Background Art

[0002] Gas, also known as coalbed methane, is a type of hydrocarbon gas attached to the surface of coal matrix particles in coal or dissolved in coalbed water. It is colorless, odorless, flammable and explosive. Gas with a concentration below 30% can be extracted from underground coal seams by a water ring extraction pump. Low-concentration gas can be transported using a transmission pipeline. In order to prevent explosions during the transportation of low-concentration gas in the transmission pipeline, it is necessary to use a transmission pipeline with a water mist explosion-proof device to transport the gas.

[0003] At present, when using water mist delivery pipelines to transport low-concentration gas, multiple fixing bolts are used to fix the two sections of the pipeline at the joints, and rubber sealing rings must be set at the ends of the two sections of the pipeline to prevent leakage. This rubber sealing ring is often composed of a single layer, which makes it easy for the rubber sealing ring to be damaged under long-term extrusion of the pipeline, thereby causing gas leakage. Therefore, we propose a gas water mist delivery pipeline to solve the above problems. Utility Model Content
