Abstract
In order to effectively control the explosion accident disasters of low-concentration gas transmission pipelines and improve the safety of low-concentration gas transmission and utilization process, the paper has summarized and analyzed the current three types of low-concentration gas transmission pipeline explosion suppression technologies and devices used in the field, including powder suppression, inert gas suppression and fine water mist suppression, and put forward the problems of coal mine gas transmission pipeline explosion suppression technologies. It is of great practical significance to pipeline transmission and utilization of low-concentration gas.
Highlights
Gas is a kind of hydrocarbon gas associated with coal, and it is a high quality clean energy
Explosion suppression technology is one of the important measures to control gas explosion disasters in pipelines, and explosion suppression materials are a key factor affecting the performance of explosion suppression devices
Explosion suppression media can be divided into powder, inert gas and fine water mist according to the existence form and suppression effect
Summary
Gas is a kind of hydrocarbon gas associated with coal, and it is a high quality clean energy. In order to effectively control the explosion accident of low-concentration gas transmission pipelines and improve the safety of low-concentration gas transmission and utilization, the paper summarized and analyzed the current research status of domestic explosion-proof technology theories and devices, and pointed out the main problems existing in current research and practical applications. It provides a reference for the construction and development of low-concentration gas pipeline transmission and utilization systems
