Significance of-Pulse jet bag filter

Pulse Jet Bag-Filter

On account of rather 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 available manufactured from different medias and equipped to present specific filtering efficiencies while operating a range of temperatures, chemistry, and dampness level. Pulse Jet Bag Filter are substitution of ESP and reverse gas fabric filters as the workhouse for particulate collection for solid fuel fired power plant and industrial boilers. This technique offers an enhanced particle filtration during wide range of functioning conditions. On changes in fuel or minor upset in boiler, there is no impression in the performance. In this form of filter, a wire cage in each bag keeps it secure from collapsing during normal filtration. When the flowing gas passes from the outside of the bag to the fabric, the dust elements form a layer on the surface of the bag. Cleanup the Pulse Jet Bag Filter is accomplished 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 piled dust layer is falling off by the resulting shock wave and falls into the hoppers. Later dust is collected from the hoppers away from the fabric filter by dust transportation 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 engineered using long bag technology
2-They have built-in Gas and Dust Distribution Devices.
3-They have an superior pulse system.

Benefits of using Pulse Jet Bag Filter:-
1- Pulse Jet Bag Filters minimize equipment footprint.
2-They cut down field construction time and cost.
3-Their preservation cost is low than others.
4-They have less ancillary elements.
5-They improve cleansing capability.
6-They reduce pressure loss.
7-They decrease compressed air use and power consumption.
8-They enhance bag life.
9-They remove forced outages for fabric maintenance.
10-Clean-side maintenance minimizes personnel exposure to fly ash and sorbet.
11-They can be designed according to particular site.
12-Their setting up cost is lower than others.
13-They reduce project lead time.
14-They decrease potential for casing leak.
15-They minimize tube sheet deflection to maintain bag alignment.
16- They reduce the impact 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 cleaned up line by line. Cleansing sequence is mechanically controlled 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 highest cleaning performance.

2- Off-line:-
It incorporates the advantages of a pulse jet bag filter as well as that of a reverse air bag house. Each component of the form of pulse jet bag filter is comparable to online pulse jet bag filter. The cleaning process of this type of pulse jet bag filter consists of sequentially isolating each compartment and then cleaning the isolated compartment with compressed air. Generally off-line bag filter is employed for larger gas volume and suitable for light and fine dust particles.
