Bag dust collector is a dry dust removal device, which is suitable for collecting fine, dry, non-fibrous dust.
The filter bag is made of textile filter cloth or non-textile felt. The filtering effect of the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy specific gravity settles due to the action of gravity. When the gas containing fine dust passes through the filter material, the dust is blocked and the gas is purified.
As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference on both sides of the filter material is large, some small dust particles that have been attached to the filter material will be squeezed out. Reduce dust collector efficiency.
Besides, high resistance power will significantly decrease air volume of the dust collecting system. Therefore, after the dust collector resistance reaching a certain volume, the dust should be cleaned in time. When cleaning, do not damage the first layer to avoid a decrease in efficiency.
The structure of the bag dust collector is mainly composed of the upper box, the middle box, the lower box (ash hopper), the ash cleaning system and the ash discharge mechanism.
In addition to the correct selection of filter bag materials, the dust cleaning system plays a decisive role in the performance of the bag dust collector.
For this reason, the dust cleaning method is one of the characteristics that distinguishes the bag dust collector, and it is also an important part of the operation of the bag dust collector.
