Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a pulse bag dust collector. Background Art

[0002] The pulse bag filter is a new type of high-efficiency pulse bag filter that is improved on the basis of the bag filter. In order to further improve the pulse bag filter, the modified pulse bag filter retains the advantages of high purification efficiency, large gas processing capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. During operation, the dust-containing gas enters the ash hopper from the air inlet duct, the coarse dust particles fall directly into the bottom of the ash hopper, and the fine dust particles enter the middle and lower boxes upward with the turning of the air flow. The dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean air collection pipe-exhaust duct, and is discharged to the atmosphere through the exhaust fan. The cleaning process is to first cut off the clean air outlet duct of the room, so that the bag of the room is in a state where there is no airflow passing through. Then open the pulse valve and use compressed air for pulse spray cleaning. The closing time of the cut-off valve is sufficient to ensure that the dust peeled off from the filter bag after spraying settles to ash.
