Chemical Industry Dust Removal

Explosion of dust to far more complex than the combustible substance and combustible gas in general, combustible dust suspended in the air formed in the explosion concentration range of the dust cloud, under fire effect, and fire point contact part of the dust was first ignited and the formation of a small ball of fire. Under the action of the heat generated by the small ball of fire, the surrounding dust is heated, the temperature increases, the ignition burning phenomenon occurs, so the ball will rapidly expand and form a dust explosion.

After the occurrence of the dust explosion, tend to produce secondary explosion which is due to the first explosion, there are a lot of dust deposition together, its concentration exceeds the dust explosion limit concentration values would not explode. But when the formation of the first explosion shock waves or will be dust deposition to be raised, in the air is mixed with the air, concentration in the dust explosion limits may followed by the secondary explosions. The second explosion caused by the disaster is often more serious than the first explosion.
