Baghouse Cleaning Methods
Baghouses come in 4 main design classifications based on "How the bags are cleaned" in other words, how the dust cake accumulation is removed and "managed".
| Styles | Method | Airflow | A/C Ratio |
|---|---|---|---|
| Pulse Jet System | Uses high-pressure air directed down into the clean side of a filter bag in order to remove the dust cake from the surface of the media. | This cleaning system can operate with airflow still going through the bag to the exhaust fan (on line cleaning). | Generally, from 4-6 to 1. |
| Shaker Style System | Physically shakes the bags in order to mechanically release the dust cake. | The style of cleaning method requires the bag “module” or compartment to be isolated from the gas stream to the exhaust fan (off-line cleaning). | Generally, from 2-4 to 1. |
| Reverse Air System | Physically collapses the bags in order to mechanically “shear” the dust cake from the bag surface. Airflow: | This style of cleaning method requires the bag “module” or compartment to be isolated from the gas stream to the exhaust fan (off-line cleaning). | Generally, from 1-3 to 1. |
Combinations and variations
- Shaker with Reverse air assist: (off-line cleaning)
- Traveling manifold reverse air: (on-line cleaning)
- Plenum pulse: usually off-line
