Dust explosion and explosion suppression demonstration device and demonstration method thereof

Abstract

The invention discloses a dust explosion and explosion suppression demonstration device and a demonstration method thereof. The dust explosion and explosion suppression demonstration device comprises a visual shell provided with a pressure relief hole, a dust raising device, a temperature and humidity monitor, an igniter and an atomizer, and the dust raising device, the temperature and humidity monitor, the igniter and the atomizer are installed in the shell. The dust raising device comprises a dust box and a fan mounted on the inner wall of the dust box. The atomizer and the igniter are both mounted at the bottom, far away from the dust box, of the shell. The atomizer is additionally arranged in the visual shell, the dust explosion suppression process can be simulated on the basis of simulating the dust explosion process, and the temperature and humidity in the shell in the whole explosion process and the explosion suppression process are recorded and analyzed through the temperature and humidity monitor; and the possibility, destructive power and countermeasures of dust explosion are fully known, so that an intuitive simulation process is provided for safety management personnel and firefighters.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a dust explosion and explosion suppression demonstration device and a demonstration method thereof. Background technique [0002] In recent years, dust explosion accidents have occurred frequently, causing varying degrees of economic losses and casualties. Dust explosion is a research hotspot for scientific researchers. As safety supervisors and students of safety-related majors, they should fully understand the principle, form and suppression methods of dust explosion. For fire rescue teams, they should fully understand the possibility, destructive power and countermeasures of dust explosions. At present, the automatic demonstration device of dust explosion and the demonstration device of explosion suppression are blank. Relevant scholars at home and abroad have researched this topic from different angles. Researchers have built different experimental devices in the p...
