Background
Currently, the energy demand in China still increases, and although the proportion of coal in the total energy consumption is continuously reduced, considering that renewable energy is difficult to replace traditional fossil energy on a large scale in a short period, coal still serves as 'ballast stone' and 'stabilizer' for energy supply in China. However, high gas or coal and gas outburst mines in China have large occupation ratio, nearly 2000 seats of ground fixed type gas extraction pump stations are built, the purity of extracted gas in coal mines is about 128 billion cubic meters every year, the annual utilization rate of 2020 is only 44.5%, and the utilization potential of extracted gas is large. In addition, gas extraction and utilization are important measures for promoting safe production of coal mines, and have great significance for realizing the double-carbon target in China.
Because the gas permeability is poor due to the geological conditions of the coal field in China, the concentration of extracted gas is mostly low-concentration gas within an explosion range (5% -15%) and with large fluctuation, and certain potential safety hazards exist in the gas extraction and utilization process. At present, a fixed type gas extraction system and a gas extraction conveying and utilizing system for coal mine ground in China adopt a mode that a split dry flame arrester and a water seal flame arrester are connected in series for use, are designed on the basis of preventing burning flame of high-concentration gas outside an explosion concentration range, and cannot prevent explosion flame and explosion shock waves. Although the explosion-proof pipeline dry-type flame arrester is used in a low-concentration gas extraction and utilization pipeline system in recent years, the problems that the fire-retardant core is easy to block and difficult to clean exist, and the illegal and dangerous operation that some users take out the fire-retardant core is not used is caused; the water seal flame arrester is used for multiple times, and the phenomenon of waste explosion during over-explosion prevention also occurs. The explosion is often an alternate cycle of 'explosion-combustion-explosion', the dry flame arrester prevents the explosion flame but does not continuously prevent the combustion flame, and the water seal flame arrester prevents the combustion flame but does not prevent the explosion flame. The existing fire retardant equipment has potential safety hazards in low-concentration gas extraction and utilization.
