Abstract

The invention provides a system for actively suppressing explosion of toxic or harmful gases, and belongs to the technical field of explosion suppression. The system comprises a vacuum pipeline segment, an inert dust pipeline segment, a gas conveying pipeline segment, pressure induction valves, an air pump, a check valve and a semi-spherical spray head. The toxic gas enters from the left side of the gas conveying pipeline segment and burns on the left side. One pressure induction valve is arranged at the junction between gas conveying pipeline segment and the vacuum pipeline segment, and the air pump maintains a vacuum state in the vacuum pipeline segment at all times. The check valve and the semi-spherical spray head are arranged at the junction between the inert dust pipeline segment andthe gas conveying pipeline segment, another pressure induction valve is arranged at the junction between the vacuum pipeline segment and the inert dust pipeline segment, and the pressure induction valve is connected with the check valve. the system suppresses the explosion of the toxic or harmful gases in the conveying process, thus reducing the severity of accident consequences.

Description

technical field [0001] The invention relates to the technical field of explosion suppression, in particular to a system for actively suppressing poisonous and harmful gas explosions. Background technique [0002] Most industrial accidents are caused by explosions, especially the explosions of toxic and harmful gases have far-reaching effects, so it is particularly important to prevent accidents. The prevention and control of explosion disasters involves many complex physical and chemical processes, and there are usually three prevention and control measures: explosion isolation, explosion suppression, and explosion venting, among which explosion suppression is an important means. The basic working principle of explosion suppression is to pre-form an explosion suppression zone composed of inert dust on the explosion propagation channel to extinguish and attenuate the explosion flame and shock wave that arrives immediately, so as to achieve the purpose of controlling the range...
