[0002] Bag dust collection is a very common dust removal equipment in industrial production processes. The bag dust collector sends dust-containing air into the dust collector box through the air inlet pipe. The dust-containing air passes through the bags, and the dust is filtered by the bags and falls into the ash hopper for collection. The filtered air is discharged into the atmosphere, and the dust in the ash hopper is recovered using a recovery device.
