Abstract

The embodiment of the invention provides a system and method for detecting the anti-knock performance of a structure, a terminal and a method for the terminal and belongs to the technical field of chemical engineering. A simulated explosion box of a special structure is constructed, then combustible mixed gas in the simulated explosion box is ignited, and therefore, an explosion situation caused by gas leakage in the actual industrial environment is restored, environmental parameters around the structure during gas explosion are measured, and the anti-explosion performance of the structure isfurther evaluated.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a detection system, method and terminal for the antiknock performance of structures. Background technique [0002] There are a large amount of flammable and explosive substances in petrochemical installations. Once an explosion accident occurs, it will cause damage to buildings and structures, and may cause a large number of casualties to people in the buildings. Accidents in refining and chemical enterprises in recent years have shown that accidents related to steam cloud explosions (combustible vapor clouds) caused by equipment leakage have a wide range of damage and huge destructive power, often causing a large number of casualties in personnel concentrated places near the equipment. [0003] The current research mainly focuses on the mixed explosion experiment of flammable gas and combustion-supporting gas and the determination of the explosion limit, but there is a...
