Anti-explosion pulse bag dust collector profile

With the strengthening of environmental awareness, people’s requirements for the polluting gases emissions of business are more and more stringent, and the bag filter is the air pollution control and efficient dust removal equipment. Bag filters have advantages of stable operation, wide application range, high collection efficiency, whose dust emission concentration is less than 10mg/m³. Because of these advantages, bag filters have been applied in many enterprises. However, with the popularity of bag filter, bag filter’s dust explosion accidents have also occurred, thus anti-explosion design for bag filters is increasingly stringent.

Dusty gas combustion and explosion must meet the following three conditions: Firstly, the concentration is within the explosion limits; secondly, the oxygen content is greater than 13%; thirdly, the ignited fire has the strong heat source. Bag filters are used in the combustible dust situations, which is necessary to take effective measures to avoid the generation of the above three conditions, that is to reduce the sensitivity of the explosive energy system, reducing the possibility of explosion. Design measures means that the measures dropping the explosion risk level to a safe level when preventing the explosion existence is ineffective, the explosion will not cause casualties, and the technical equipment will not restore in a short time after the explosion.

In addition, the operator can safely operate the equipment, which is the key to avoid dust explosions, and therefore strengthening the management of staff is also very important. Training operators for the theoretical knowledge is to make the operator s be aware of the danger of dust explosion and how to effectively avoid dust explosion; strengthening labor discipline should always pay attention to bag filters’ operation in working; absolutely prohibit the welding and gas cutting in the working of bag filters, and the fire into the bag filters.
