The experimental device has a novel, unique, simple and reasonable structure, the experiment method is simple, the experiment process is stable and directly visual, the use method is easy to operate and control, the atomization amount is achieved by pressure adjustment of a gas bottle, and the explosion suppression effect is great.

Description

Technical field [0001] The invention relates to a fire safety experimental device, in particular to a dual-fluid inerted water mist suppression pipeline gas explosion experimental device and an experimental method. Background technique [0002] Gas is widely present in coal-bed methane, mine ventilation gas and chemical gas. It is often caused by explosion in mine tunnels, gas pipelines and gas storage equipment. It has become one of the most concerned safety issues in my country. With the development of society, higher requirements are placed on explosion suppression technology, that is, while suppressing explosions, it is required to be environmentally friendly and non-polluting to the process medium. Therefore, it is imperative to study clean and efficient explosion suppression technology. [0003] Inert gas and water mist are common economical and environmentally friendly fire extinguishing and explosion control materials. At present, the corresponding inert gas and water mist...
