A brief Introduction about Pulse Jet Bag Filter

 Pulse Jet Bag Filter

Because of rather low-cost and small-sized, pulse jet Bag filter is very popular in the solid production industry. Now a days bag filters for bag houses are offered made of several medias and furnished to produce particular filtering efficiencies while dealing with a variety of temperatures, chemistry , and dampness level. Pulse Jet Bag Filter are alternative of ESP and reverse gas fabric filters as the workhouse for particulate collection for solid fuel fired power plant and industrial boilers. This technology presents an improved particle filtration during wide range of working conditions. On changes in fuel or minor upset in boiler, there is no effect in the performance. In this type of filter  , a wire cage in each bag keeps it protected from collapsing during usual filtration. When the flowing gas moves from the outside of the bag to the fabric, the dust crystals form a coating on the surface of the bag. cleanup 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. These short period air pulse exits the blowpipe orifices and travel down the filter bags.

Pulse Jet Bag Filters


The accumulated dust layer is falling off by the resulting shock wave and falls into the hoppers. afterwards dust is collected from the hoppers away from the fabric filter by dust transport system for beneficial re-usage or disposal. Operation and managing  of the fabric filter cast influence upon preservation 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 superior pulse system.
   
Benefits of using Pulse Jet Bag Filter

    1- Pulse Jet Bag Filters minimize equipment footprint.
    2-They reduce field construction time and cost.
    3-Their servicing cost is low than others.
    4-They have less ancillary elements.
    5-They boost cleaning efficiency.
    6-They cut down pressure loss.
    7-They decrease compressed air use and power consumption.
    8-They boost bag life.
    9-They remove forced outages for fabric maintenance.
    10-Clean-side preservation decreases personnel exposure to fly ash and sorbet.
    11-They can be designed according to specific site.
    12-Their set up cost is lower than others.
    13-They minimize project lead time.
    14-They minimize potential for casing leak.
    15-They lessen 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. Cleaning sequence is automatically handled 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 accomplishing optimum cleansing effectivity.

2- Off-line
It incorporates the benefits of a pulse jet  bag filter as well as that of a reverse air bag house. Each part of the this form of pulse jet bag filter is comparable to online pulse jet bag filter. The cleaning operation 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 utilized for larger gas volume and suitable for light and fine dust particles.
