The (SFI) Pulse Jet Bag Filter:
In an online bag filter, bags are cleaned row by row, even while the dust-laden gas is filtered concurrently. The sequence of cleaning is controlled automatically by a sequence controller. This operates the assembly of solenoid and pulse valves which direct the air flow into the manifolds. The holes are jig drilled for perfect alignment with the venturi center for achieving maximum cleaning efficiency.
It incorporates the advantages of a pulse jet bag filter as well as that of a reverse air baghouse. Each compartment is similar to an online pulse jet bag filter. The cleaning process consists of sequentially isolating each compartment and then cleaning the isolated compartment with compressed air. Offline cleaning is suitable for light and fine dust where the occurrence of fluidization is a distinct possibility. Generally, the Offline Bag Filter is employed for larger gas volumes.
Regular Hopper Entry:
The pulse jet bag filter in its most rudimentary form basically consists of the filtration elements housed in a casing. Below this casing is a hopper with a discharge valve, to continuously remove the dust that is collected on the bags. The entire unit is supported from the ground on structural legs. A caged ladder provides access to the top of the unit for maintenance.
The dust-laden air enters through the hopper by suction (normally) or (positive pressure). The heavier dust particles fall off at the entry itself, while the lighter dust gets carried upward to the bags.
Flush Mounted - Insertable:
Transfer points involving two conveyors or from one conveyor to/from other material handling equipment often involve isolated point(s) where a free-standing bag filter(s) can be an expensive proposition. Space availability on the ground is also an issue at times. Typically, these insertable bag filters units are devoid of any hopper. The unit can be suitably positioned on the conveyor directly. On pulsing, dust falls back onto this conveyor, thus avoiding a need for a separate dust discharge hopper.
Depending on the height of fall of dust, two such insertable bag filters may be required – one at the end of the discharging conveyor and one on the receiving conveyor. When a single unit is used, it is normally on the receiving conveyor – as shown in the adjoining figure – this being where the generation of dust is higher due to impact. These type of units are also optimal solutions for venting bins/silos/hoppers.
Flush Mounted - Circular:
The construction here is similar to an insertable bag filter; however, in this case, the casing of the bag filter is circular instead of being rectangular. The top cover could be a dished end – as in the adjoining figure – which is used for high positive design pressure or vacuum, as is typically a situation encountered for applications related to venting of silos/bins connected to pneumatic conveying systems.
