Fabric Bag Dust Collector

Baghouse dust collector is a dry type dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, using the filtering effect of the fibre fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will settle down and fall into the dust hopper due to gravity, and the gas containing fine dust will be blocked when it passes through the filter material, so that the gas will be purified.

Bag filter is a kind of dry dust filtering device. After a period of time, due to filtering, collision, retention, diffusion, electrostatic and other effects, the filter bag surface accumulates a layer of dust, this layer of dust is called the initial layer, in the subsequent movement, the initial layer of the filter media has become the main filtration layer, relying on the role of the initial layer of the filter media with a larger pore size to obtain a higher filtration efficiency. With the accumulation of dust on the surface of the filter media, the efficiency and resistance of the dust collector are increased accordingly, when the pressure difference between the two sides of the filter media is very large, some of the fine dust particles that have been adhered to the filter media will be squeezed through, so that the efficiency of the dust collector decreases. In addition, the dust collector resistance is too high will make the air volume of the dust collector system drop significantly. Therefore, after the dust collector's resistance reaches the value, it should clear the dust in time. When clearing the dust, the initial layer should not be destroyed, so as to avoid the efficiency dropping.

Main features

(1) Dust removal, generally above, the dust concentration of the dust collector outlet gas containing dust within tens of mg/m3, the sub-micron particle size of fine dust has a high grading efficiency.

(2) a wide range of processing air volume, small only 1min several m3, large up to 1min tens of thousands of m3, used in industrial furnaces and kilns flue gas dedusting, reduce the emission of air pollutants.

(3) Simple structure, easy maintenance and operation.

(4) Under the premise of the same efficiency, the cost is lower than the electric precipitator.

(5) When glass fibre, PTFE, P84 and other filter materials are used, it can be operated under high temperature conditions above 200℃.

(6)It is not sensitive to the characteristics of dust and is not affected by dust and resistance.
