Automatic explosion suppressing device applicable to dust explosion in pipeline

Abstract

The invention relates to an automatic explosion suppressing device applicable to dust explosion in a pipeline. The automatic explosion suppressing device comprises flame sensors, pressure sensors, a high-pressure explosion suppression agent container and a small-sized detonation device, wherein a carbonate powder explosion suppression agent is placed in the small-sized detonation device, the high-pressure explosion suppression agent container is filled with a high-pressure N2 gas explosion suppression agent, a rupture disc is arranged between the high-pressure explosion suppression agent container and the small-sized detonation device and is used for separating high-pressure N2 gas of the high-pressure explosion suppression agent container, a rupture disc diaphragm is arranged between the small-sized detonation device and a powder conveying pipeline and is used for supporting the carbonate powder explosion suppression agent, the flame sensors and the pressure sensors are connected with a controller, and the controller is connected with the small-sized detonation device and is used for controlling to trigger the small-sized detonation device, so that the high-pressure N2 gas explosion suppression agent in the high-pressure explosion suppression agent container and the carbonate powder explosion suppression agent enter the pipeline at high speed, and thus, explosion suppression is realized. According to the automatic explosion suppressing device applicable to the dust explosion in the pipeline, quick response to an explosion accident in the pipeline can be carried out, so that the occurrence of the explosion accident or the further expansion of harm is avoided.

Description

technical field [0001] The invention relates to an explosion suppression device suitable for dust explosion accidents in pipelines, which can respond quickly to explosion accidents in pipelines (response within the order of ms, or even faster), and avoid the occurrence of explosion accidents or further damage caused by accidents. expand. Background technique [0002] With the development of modern industry, powder products are increasing day by day, and its explosion hazard involves almost all industrial sectors, which greatly increases the potential danger of dust explosion. A dust explosion is an explosion that occurs when combustible solid particles suspended in the air come into contact with an ignition source such as a flame (open flame) or an electric spark. Dust explosions mostly occur in industries such as metallurgy, military industry, textile, fiber, food, and pharmaceuticals; dust explosion accidents may occur in metal dust, coal dust, plastic dust, organic dust,...
