Because of relatively low-cost and small-sized, pulse jet Bag filter is very famous in the solid producing industry. Now a day’s bag filters for bag houses are present product of different medias and furnished to provide particular filtering efficiencies while dealing with a variety of temperatures, chemistry, and dampness point. Pulse Jet Bag Filter are substitute of ESP and reverse gas fabric filters as the workhouse for particulate collection for solid fuel fired power plant and industrial boilers. This technique guarantees an enhanced particle filtration during wide range of performing conditions. On changes in fuel or minor upset in boiler, there is no effect in the performance. In this style of filter, a wire cage in each bag keeps it secure from collapsing during usual filtration. When the flowing gas moves from the outside of the bag to the fabric, the dust particles form a coating on the surface of the bag. cleaning up the Pulse Jet Bag Filter is done by controlled pulses of compressed air into each filter bag through a blow pipe and orifice assembly mounted just above the filter bag. These short period air pulse exits the blowpipe orifices and travel down the filter bags. The gather dust layer is falling off by the resulting shock wave and drops into the hoppers. In the future dust is collected from the hoppers away from the fabric filter by dust transport system for beneficial re-usage or disposal. Functioning and controlling of the fabric filter cast influence upon maintenance cost as well as emission.

Feature of Pulse Jet Bag Filters-
1- They are developed using long bag technology
2-They have built-in Gas and Dust Distribution Devices.
3-They have an enriched pulse system.

Benefits of using Pulse Jet Bag Filter:-
1- Pulse Jet Bag Filters cut down equipment footprint.
2-They minimize field construction time and cost.
3-Their repair cost is low than others.
4-They have less ancillary components.
5-They increase cleansing proficiency.
6-They lessen pressure loss.
7-They lessen compressed air use and power consumption.
8-They enhance bag life.
9-They eliminate forced outages for fabric maintenance.
10-Clean-side repair reduces personnel exposure to fly ash and sorbet.
11-They can be designed according to distinct site.
12-Their set up cost is lower than others.
13-They cut down project lead time.
14-They lessen potential for casing leak.
15-They decrease tube sheet deflection to maintain bag alignment.
16- They reduce the influence to filter media due to excursion or abnormal operating conditions.

Types of Pulse Jet Bag Filters:-

1-Online -
In an online pulse jet bag filter, bag is washed line by line. Cleansing sequence is automatically managed by sequence controller. This works the simultaneously solenoid and pulse valves which direct the air flow into the manifold. The holes are jig drilled for perfect alignment with the venturi center for obtaining optimum cleaning effectiveness.

2- Off-line:-
It incorporates the advantages of a pulse jet bag filter as well as that of a reverse air bag house. Each element of this kind of pulse jet bag filter is comparable to online pulse jet bag filter. The cleaning technique of this form of pulse jet bag filter is made of sequentially isolating each compartment and then cleaning the isolated compartment with compressed air. Generally off-line bag filter is used for larger gas volume and suitable for light and fine dust particles.
Amrit Filtration Equipments is a renowned manufacturer and supplier of pulse jet bag filter and other filtration equipments, such as dust collector filter bags where the writer is working on the designation of technical of Pulse Jet Bag Filter.
Pulse Jet Bag Filter is a standard product of Amrit Filtration Equipments and very helpful to control air pollution.
