Improper selection of bag: different particles have different characteristics such as particle size, density and shape, so it is necessary to choose the corresponding bag material, otherwise it will lead to poor dust removal effect.

Failure to clean the bag in time: During the long-term operation of the bag dust collector, particles will gradually accumulate on the bag and need to be cleaned in time. If the dust removal is not timely, it will lead to the increase of bag resistance and affect the dust removal effect.

Bag damage: During the operation of the bag dust collector, the bag may be scratched or damaged by particles, resulting in the gas not passing through the bag, thus affecting the dust removal effect.

Excessive gas velocity: If the gas velocity is too large, the particles will not be deposited on the cloth bag, but will be taken away by the airflow, and the dust removal effect is not good.

Poor sealing of filter bag: If the filter bag and dust collector are poorly sealed, gas will bypass the filter bag and be directly discharged into the atmosphere, which will affect the dust removal effect.

Unreasonable operation parameters: the operation parameters of bag filter include gas flow, inlet and outlet pressure, cleaning cycle, etc. If these parameters are set unreasonably, the dust removal effect will also be affected.

Therefore, in order to ensure the dust removal effect of bag filter, it is necessary to select suitable filter bag materials, clean the dust in time, protect the filter bag and adjust the operation parameters.
