The reverse blowing bag filter is a highly automatic dust removal equipment with off-line automatic dust removal function. It is equipped with pressure measuring instruments or time relays inside, which can automatically complete the accumulation in the filter bag under the set pressure or time. gray treatment. The back-blowing belt dust collector is equipped with a cleaning valve on the back-blowing air pipeline, which can balance the pipeline pressure and clean the dust in the back-blowing air pipeline. There are two gas flow directions when the anti-air blowing filter bag is dedusting, one is that the airflow enters and flows upward from the bottom of the dust collector, and the other is that the airflow enters and flows downward from the top of the dust collector. The backflush bag dust collectors of these two gas flow modes are slightly different in structure and working principle.
1. The lower air intake and reverse blowing belt dust collector The lower air intake and reverse blowing belt dust collector arranges the air inlet below the dust collector, guides the air flow from bottom to top through the filter bag and enters the clean air chamber, and then the induced draft fan removes the dust The final clean air is discharged through the flue. When cleaning the dust, the lower air intake reverse blow bag filter will close the main air valve, open the reverse blow valve for dust removal, and deliver clean air from the clean air pipeline to the filter bag room to remove the accumulated dust inside.
2. Upper air intake and reverse blowing bag type dust collector The upper air intake and reverse blowing bag type dust collector arranges the air inlet above the dust collector, guides the air flow from top to bottom through the filter bag and enters the clean air chamber, and then the induced draft fan will The clean air after dust removal is sucked out and discharged through the flue. The gas flow direction of the upper air intake and reverse blowing belt dust collector is consistent with the falling direction of dust gravity. When the dust is trapped by the filter bag, some dust with larger particle size will not adhere to the filter bag, and will directly follow the airflow. The flow falls into the ash hopper, which reduces the chance of dust flying again and helps improve the working efficiency of the dust collector.
