The invention provides an experiment device and method for researching the gas-explosion wall-face effects. The whole experiment device comprises a cylindrical anti-explosion container, a circular explosion pipe, a pressure testing system, a vibration acceleration testing system, a gas distributing system, an ignition system, a synchronous control system, a data collecting device and a stretchable moving support. Research in the wall-face effects on flammable gas explosion can be carried out, and the wall-face effects include the wall-face resistance effect, the wall-face reflection effect and the wall-face heat effect. According to the three wall-face effects, a spring-type resistance wall face, a reflecting metal anti-explosion plate and a pipe heater are respectively designed. As the wall-face effects in the pipe in the flammable-gas-explosion propagation process are developed, the explosion propagation rule of flammable gas can be revealed, combustion explosion accidents can be further prevented and controlled, and the reference is provided for engineering anti-explosion safety design.
Description
technical field [0001] The invention relates to an experimental device and method for studying gas explosion wall effects, belonging to the technical field of combustible gas explosion safety research. Background technique [0002] In industrial development, especially in petrochemical production, combustible gases have been widely used as raw and auxiliary materials or products. In most cases, the storage and transportation of flammable gases are carried out through containers or pipelines. Once negative pressure, sealing failure or gas distribution errors cause air to mix in to form explosive mixtures, explosion hazard accidents are extremely likely to occur. Therefore, the study of the characteristics of the propagation process of combustible gas explosion has been a major research topic for scholars from all over the world. [0003] The explosion propagation of combustible gas in pipelines is a typical gas explosion process. The focus of current research is mainly on th...
