        The use of dust collector dust explosion how to pay attention to?
 
 
1) dust explosion than combustible substance and combustible gas is much more complex, combustible dust suspended in the air are formed in the explosion concentration range of the dust cloud, in an ignition source of ignition source, and the contact portion of dust was first ignited and the formation of a small ball of fire. In this small fireball combustion heat release effects, makes the adjoining dust is heated, temperature, combustion phenomena, such as fireball will expand rapidly and the formation of dust explosion.
 2) dust explosion, tend to produce two explosion which is due in the first blast, there are a lot of dust deposition together, their concentrations exceed the dust explosion limit concentration values cannot explode. However, when the first explosion shock waves formed or deposited dust to be raised, in the air is mixed with the air, concentration in dust explosion limits, it may then have two times of explosive. The second explosion disasters caused by more often than in the first explosion is much more serious.
3) the mechanism of dust explosion of combustible dust in the air in the combustion will release energy, generate large amounts of gas wells, and energy release speed combustion velocity and powder is exposed in the air in the relevant area. Thus, substances with a solid powder, its particle size smaller than a surface area of, the larger, the faster the spread of combustion. If the solid fine particle size. That can be suspended, as soon as the ignition source to ignite, can in a very short time to release a lot of energy. These energy not dissipated into the surrounding environment, the space within the gas is subjected to heating and adiabatic expansion, and on the other hand powder combustion produces large amounts of gas, will make the system form local high pressure, resulting in explosion and propagation, which is usually called the dust explosion.
 4) dust explosion and combustion difference large solid combustibles combustion is nearly parallel to the inner layer in advance, such as coal combustion. The combustion energy released more slowly. The heat generation and gas can be rapidly releases. Combustible dust heap shape combustion, in good ventilation condition form fire, but in good ventilation condition. Smokeless flame can be formed or smouldering.
5 ) in view of the above, it developed the " fire and explosion dust collector", in the control of dust concentration, fire alarm and fire box and so on several aspects, the actual use of good results, by the majority of users of praise.
