Gas generator structure for assembling explosion suppression device

Abstract

The invention discloses a gas generator structure for assembling an explosion suppression device, and belongs to the technical field of explosion suppression. The gas generator structure comprises a gas production unit, an upper plug, a gas guide unit and a lower plug; a trigger element gland is installed at one end of a cylinder body of the gas production unit, and the other end of the cylinder body of the gas production unit is in threaded fit with a connector of a cavity of the explosion suppression device; a triggering element electric-point gunpowder head has instant explosion and false triggering prevent characteristics; gas generating agent is in a tablet shape and are filled with a certain density gradient; the cylinder body of the gas guide unit is filled with porous metal foam; and the ratio of the net hole area between the through hole of wall surface of the air guide unit and the through hole in the bottom surface of the lower plug is 2 to 1. According to the gas generatorstructure, the injection timeliness of an explosion suppression medium is ensured, and false triggering caused by environmental stray current is prevented; the gas production rate is increased, and the pressure aggregation process in the explosion suppression device is effectively controlled; the gas generation agent is prevented from being burned and splashed, sparks may generate by the gas generator can be extinguished so that the intrinsic safety can be guaranteed; and the ratio of the optimized side and the bottom holes, and the gas production energy distribution are more reasonable.

Description

Technical field [0001] The invention belongs to the technical field of combustible gas and dust explosion suppression, and specifically relates to a gas generator structure for assembling an explosion suppression device. The gas generator is installed on the explosion suppression device. After the gas generator is triggered, a large amount of inert gas is instantly generated to drive the suppression medium. The scene of the accident where the explosion occurred was sprayed quickly. Background technique [0002] Gas, dust / air mixture explosion accidents that occur in confined spaces can cause serious casualties and property losses. Explosion suppression technology refers to spraying (spraying) an explosion suppression medium to the explosion flame front at the beginning of an explosion to slow down and extinguish the flame propagation process to control the harmful effects of the explosion. Passive explosion suppression measures mainly rely on the explosion shock wave itself to s...

A more typical one is CN103055450A (a spontaneous explosion suppression device), which introduces the structure of the combustion chamber of the gas generator in more detail, but the gas generating agent uses smokeless gunpowder, and the gunpowder is not sealed, and there is no cooling measure. The resulting fireball and high temperature itself
