Background

A bag filter is a dry dust filter that is suitable for capturing fine, dry, non-fibrous dust. After the dust-containing gas enters the bag type dust collector, the dust with large particles and large specific gravity is settled down under the action of gravity and falls into the dust hopper, and the dust is blocked after the gas containing fine dust passes through the filter bag, so that the gas is purified.

After a traditional filter bag is used for a long time, dust on the surface of the filter bag is increased gradually, so that the filtering efficiency of the filter bag is reduced, and at the moment, the dust on the surface of the filter bag needs to be removed. The existing ash removal means generally adopts pulse type, namely compressed air is blown to the inside of a filter bag by a pulse valve, so that air waves are formed in a bag body, and meanwhile, the filter bag is rapidly expanded and shocked from top to bottom to remove accumulated ash.

However, the pulse dust cleaning device is adopted, and the compressed air conforming to the filter bag needs to be selected according to the material and the structure size of the filter bag, so that the dust cleaning mode needs larger investment and high operation cost, and needs to be improved.
