product description


Explosive or potentially explosive environments exist in most workplaces where fine aluminum dust, organic powder, or other similar dust is processed. Dust explosions can easily cause personal injury and death, damage to equipment and buildings, and pollute the air, thereby creating environmental risks. Since most combustible dusts of organic materials, synthetic materials and metals can explode, a scientific explosion-proof dust removal system is particularly necessary.

working principle


Dust explosion means that the dust particles suspended in the air are fully in contact with the oxygen in the air, and the oxidation reaction is completed instantaneously under certain conditions. A large amount of heat is released during the reaction, which results in high temperature and high pressure. Any dust explosion must have three conditions: ignition source, flammable dust, dust suspended in air and reaching the explosive concentration limit range. Explosion protection is to destroy the conditions of dust explosion and achieve the purpose of safety.

Dust explosion prevention and control measures


泄爆装置:在爆炸压力尚未达到除尘器和风管的抗爆强度之前,采用泄爆装置排出爆炸产物,使除尘器及风管不致被破坏。 Explosion venting device: Before the explosion pressure has reached the explosion-proof strength of the dust collector and wind pipe, the explosion venting device is used to discharge the explosion products, so that the dust collector and the air pipe will not be damaged.

惰化装置:向除尘器充入惰性气体或粉体,使可燃性粉尘失去爆炸性。 Inerting device: Fill the dust collector with inert gas or powder to make the combustible dust lose its explosiveness.

隔爆装置:在风管上设置隔爆装置,将火焰及爆炸波阻断在一定的范围内。 Explosion-proof device: A flame-proof device is installed on the air pipe to block the flame and explosion wave within a certain range.

抑爆装置:在风管和(或)除尘器上设置抑爆装置,爆炸发生瞬间向风管和(或)除尘器内充入用于扑灭火焰的物理、化学灭火介质,抑制爆炸发展或传播。 Explosion suppression device: An explosion suppression device is installed on the air pipe and / or dust collector. When the explosion occurs, the air pipe and / or dust collector are filled with physical and chemical fire extinguishing media to extinguish the flame to suppress the development of the explosion or propagation. Dust collectors and ducts with toxic and corrosive dust and fuel dust should not be decompressed with explosion venting devices. Instead, the dust collectors and ducts should be filled with fire extinguishing gas or powder media used to extinguish the flame. Explosive device.
