How great the dust hazard is, implement the analysis of the environmental protection dust explosion-proof dust collector manufacturer.

Release date:2021-12-09 Source:Pure-Air Pageviews:-

Explosive limit: combustible substances (combustible gas, steam and dust) must be uniformly mixed with air (or oxygen) within a certain concentration range to form a premixed gas, and explode when exposed to a fire source. This is called the explosive limit or explosive concentration limit. Dust explosion-proof dust collector, laser cutting/engraving filter

When dust is within the explosion limit, when it encounters a heat source (open flame or temperature), the flame immediately spreads to the entire mixed dust space. The chemical reaction speed is very fast, releasing a lot of heat, forming high temperature and high pressure, and the system energy is converted into mechanical power and light and heat radiation. Destructive power is strong. laser dust

laser dust

Common explosive dust can be divided into seven categories: metal (such as magnesium powder, aluminum powder); coal; grain (such as wheat, starch); feed (such as blood meal, fish meal); agricultural and sideline products (such as cotton, tobacco); forest products ( Such as paper powder, wood powder); synthetic materials (such as plastics, dyes). laser dust cleaner

Generally explosive dust generally includes aluminum powder, zinc powder, ferrosilicon powder, magnesium powder, iron powder, aluminum processing grinding powder, various plastic powders, intermediates, wheat flour, sugar, sawdust, dyes, bakelite ash, milk powder, tea Powder, tobacco powder, coal powder, plant fiber powder, etc. The dust of these materials is easy to explode and burn because they all have strong reducing agents H, C, N, S. When they coexist with peroxides and explosive dust, they will decompose and produce a large amount of gas through oxidation reaction. Or although the amount of gas is small, it will release a lot of heat of combustion. For example, aluminum powder has a risk of explosion in a carbon dioxide atmosphere.
