At present, with the rapid development of industrialization in China, the dust explosion occurred many times in the process of enterprise production, which affected the loss of enterprise property and caused the unsafe factors of the enterprise, and the enterprise must raise the consciousness of safety to reduce the enterprise's loss. How much harm will the dust explosion be?

How should we guard against it?

Main hazard of dust explosion (1) Extremely destructive.

Dust explosion involves a wide range of coal, medicine, chemical, wood processing, food and feed processing departments are often. (2) Dust explosion is easy to produce two times. The first explosion blast the dust deposited on the equipment or ground, in the short time after the explosion, the central area of the explosion will form negative pressure, the surrounding fresh air will be filled in from the outside, forming the so-called "return Wind", mixed with the dust raised, in the first explosion of the fire ignited a second explosion. At two explosions, the dust concentration is generally much higher than an explosion, and two explosions are much more powerful than the first.

He will affect the electrical and equipment circuit control system explosion combustion, can produce different poisonous gas is often caused by the explosion after the large number of human and animal poisoning casualties, we must pay full attention to.

How to prevent dust explosion First, it is to reduce the concentration of dust in the air.

The use of good airtight equipment, to minimize dust emission escape, at the same time to install effective ventilation and dust removal equipment, strengthen clean-up work.

Second, it is to control indoor temperature. Third, it is to improve equipment, control of ignition.

Where there is danger of dust explosion, Four, the dust enterprise must choose the national quality standard explosion-proof electrical, explosion-proof motor, explosion-proof switch, explosion-proof lighting, the safety of explosion-proof cable more important, Tianjin Cable factory manager Bi remind customers to use the explosion-proof cable must be used explosion-proof IA grade. (Explosion-proof control cable, explosion-proof signal cable, explosion-proof computer cable, explosion-proof coaxial cable) in the normal working state, there is a failure in the explosion-proof cable or two failure, can not ignite the explosive gas mixture. In the type IA explosion-proof cable, the operating current is limited to 100mA, applicable to chemical industry, dust enterprises, and other uses.
