Description

Dust explosion-proof facility device

Technical Field

Background

The dust explosion refers to the dust cloud formed by mixing combustible dust with air in a limited space, and under the action of an ignition source, the formed dust-air mixture is rapidly combusted, and a chemical reaction of which the temperature and the pressure are suddenly increased is caused. Dust explosion is often accompanied with production and processing places where aluminum powder, zinc powder, aluminum material processing grinding powder, various plastic powders, intermediates of organic synthetic drugs, wheat flour, sugar, wood chips, dyes, glue wood ash, milk powder, tea powder, tobacco powder, coal dust, plant fiber dust and the like are generated. Generally, dust which is relatively liable to cause an explosion accident includes aluminum powder, zinc powder, ferrosilicon powder, magnesium powder, iron powder, aluminum material processing grinding powder, various plastic powders, intermediates of organic synthetic drugs, wheat flour, sugar, wood dust, dye, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, plant fiber dust, and the like. The reason why the dusts of these materials are easily exploded and burned is that there are strong elements such as the reducing agent H, C, N, S, and when they coexist with the peroxide and the explosion-prone dust, they are decomposed to generate a large amount of gas by oxidation reaction, or the amount of gas is small but releases a large amount of combustion heat. For example, aluminum powder is dangerous to explode if it is in a carbon dioxide atmosphere.

The danger coefficient of dust explosion is extremely high, but the danger coefficient is easily ignored by people, so the necessary protection facilities are very important, and therefore, a device is needed to be designed for solving the problem that the dust explosion is easy to occur in a production and processing place.
