How It Works

During normal operation:

  1. During normal operation, the dust laden air from the plant travels down the supply duct.

  2. The dirty air then enters the COMBIFAB material handling fan and into the filter.

  3. As the dust-laden air enters the inlet section of the filter, the air decelerates and heavier dust and shavings settle on the hopper floor.

  4. The heavier dust and shavings collected on the hopper floor are conveyed to the discharge end of the filter by the scrapers on the chain conveyor.

  5. At the discharge end of the filter, the dust is pushed into the rotary airlock and out of the filter.

  6. The remaining dust then travels up into the inside of the filter bags.

  7. The air, which originated from the plant, is now clean and passes through the filter bag and out the exhaust port.

While Cleaning:

  1. The NFK filter cleans the bag during operation (On-line cleaning) and when the unit is shut down (Off-line cleaning). The Off-line cleaning period starts after the COMBIFAB fan has stopped rotating.

  2. A PLC control in the electrical panel regulates the cycle of the reverse air regeneration fan. The regeneration fan shakes the filter bags causing the dust cake, which hangs on the inside of the filter bag, to fall into the hopper section.

  3. Any dust that remains on the inside of the filter bag after the initial “shake” is removed by the airflow generated by the regeneration fan.

  4. The dust that is removed during the cleaning cycle falls on to the floor of the hopper , and then gets transported to the discharge section of the filter by the chain conveyor.
