Pulse-Jet-Bag Filter

Pulse-Jet-Bag Filter

Because of rather low-cost and small-sized, pulse jet Bag filter is very favorite in the solid digesting industry. Now a day’s bag filters for bag houses are available made from various medias and furnished to offer specific filtering efficiencies while handling a range of temperatures, chemistry, and moisture point. Pulse Jet Bag Filter are improvement of ESP and reverse gas fabric filters as the workhouse for particulate collection for solid fuel fired power plant and industrial boilers. This technology guarantees an enhanced particle filtration during wide range of functioning 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 normal filtration. When the flowing gas flows from the outside of the bag to the fabric, the dust substances form a coating on the surface of the bag. Cleansing the Pulse Jet Bag Filter is completed by controlled pulses of compressed air into each filter bag through a blow pipe and orifice assembly mounted just above the filter bag. This short lifetime air pulse exits the blowpipe orifices and travel down the filter bags. The accumulated dust layer is dislodged by the resulting shock wave and falls into the hoppers. Afterwords 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 repair cost as well as emission.

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

Benefits of using Pulse Jet Bag Filter:-
1-Pulse Jet Bag Filters reduce equipment footprint.
2-They cut down field construction time and cost.
3-Their repair cost is low than others.
4-They have less ancillary elements.
5-They strengthen cleansing effectiveness.
6-They cut down pressure loss.
7-They minimize compressed air use and power consumption.
8-They increase bag life.
9-They remove forced outages for fabric maintenance.
10-Clean-side preservation minimizes personnel exposure to fly ash and sorbet.
11-They can be developed according to distinct site.
12-Their set up cost is lower than others.
13-They minimize project lead time.
14-They reduce potential for casing leak.
15-They lessen tube sheet deflection to maintain bag alignment.
16- They decrease 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. Cleanup sequence is mechanically handled by sequence controller. This performs 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 achieving highest cleaning capability.

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 the type of pulse jet bag filter is similar to online pulse jet bag filter. The cleaning procedure of this style of pulse jet bag filter is made up of sequentially isolating each compartment and then cleaning the isolated compartment with compressed air. Generally off-line bag filter is applied for larger gas volume and suitable for light and fine dust particles.
