Dust Collector Filter Bags

Dust Collector-Filter Bags

Dust Collector Filter Bags are most significant component of a filtration system. These are  product of glass fiber , acrylic , polyester, polypropylene, PTFE, P84 and nomex etc. These pleated dust collection bags are very efficient and provide long-lasting excellent overall performance. These pleated dust collection bags are generally used for pollution control. Dust collector filter bags are also applied in metallurgy, fertilizers and chemical production plants.

Dust Collector Filter Bags

These are essentially necessary where the dust is produced throughout processing materials. For instance flour mill, pharmaceutical factories food processing etc, where the dust and some other hazardous things can not be permitted to exhaust in open environment. Plant of these varieties implement dust collector filter bags to collect dust and some other unsafe elements. There are a wide variety of manufacturing techniques to manufacture right dust collector filter bags to fulfill all the needs of a dust collector depending up on the system of cleaning such as pulse & reverse jet and auto mechanism cleaning.

Benefits of Dust Collector Filter Bags-

    1- Its repair cost is low.
    2-Practical efficiency of Dust Collector Filter Bags are quite high.
    3-It recovers heat  very effectively.
    4-It is  effective and not affected by Gas-dust composition

Dust collector filter bags play an important role in these types of production plants who also produce dust and other harmful chemical crystals with their consumer items. These manufacturing plants are for example cement, thermal power station, fertilizers,steel pants , aluminum , zinc , lead , asbestos and chemical plants etc. Dust collector filter bags are implemented here to collect unsafe and dust crystals.

The Secondary purpose of the dust collector bags is to check pollution for instance air pollution and water pollution. In the cement industry the medium particle size of the cement dust ranges from 8 to 12 microns. When the dust collector sucks the air, air brings with it these substances inside the dust collector. Dust collector transmits the air into the dust collector filter bags. Here dust collector filter bags are liable to hold sucked particles and enable the air to pass. In all the stages of cement manufacturing , dust collector filter bags are proven to be the best because of its high-efficiency and flow rate etc. Dust collector filter bags may function  efficiently during working in different temperatures,which may vary in accordance to the process of production dry or wet in production plants in the range of 150 degree Fahrenheit to 250 degree Fahrenheit.

Varieties of Dust collector filter bags-

A- Acrylic homopolymer needle punched filter felt-
   
MS Acrylic homopolymer needle punched filter felt are offered in woven or felt form. This     product offers chemical resistance comparable to poly propylene while allowing operation up to 250 degree fahrenheit  (equivalent to 121 c).

Its feature is a great combination of filtration efficiency and dust layer release.
It presents good chemical resistance to acid and alkalis.
   
    It is utilised in chemical processing .
    It is implemented in mineral processing.
    It is applied in metal processing.


B-Antistatic Needle- Punched Filter Cloth-

MS Anti static needle punched filter cloth easily results in the explosion and conflagration after the consistency of common industrial power and dust reaches certain degree. It is handling the static electricity light and spark outside  such as flour powder, coal powder and chemical particles. To contain fine particles of dust the filter medium of bag must be anti static.
   
C- Nomex Filter Felt-

The characteristic of MS nomex filer needle felt is high temperature (between 204 ~ 240     degree), anti acid ,anti alkali , high filtration precision ,low pressure drop and  anti break .
    Its some other qualities are anti abrasion,mostly applied  in pitch mix gas, blast furnace gas of steel     factory , tail gas of while char ,kiln application and electrical cooker high temperature gas.



D- P84 Needle Punched Filer Felt-

MS p84 needle punched felt is a extreme temperature resistive filter material good chemical     repellent, good air permeability and  high filtration efficiency. It is mostly applied in coal boilers of thermal power stations.

E- Polyester (PET) Needle Punched Filter Felt-

    MS Polyester needle punched filter felt provide a cost-effective answer for a number of industrial operations. They are highly adaptable and efficient in dust collection.

F- Water and Oil Resistant Filter Cloth-

    After oil and water treatment numerous filter fabrics can form a layer of molecules obstacle around     the fiber surface. This kind of dust collector filter bags filters several pollutants from the water and oil.

G- Filter Bags with PTFE Membrane Laminating-

These dust collector filer bags are applied in all the dust collector applications. The expanded     PTFE Membrane permits more air to pass through the filter media while trapping particles on the surface. Using this form of dust collector filter bags engineers can reduce capital and     operational costs. Use of this type of dust collector filer bags also present a degree of protection from the unknown and indirect-able  changes that sometimes occur during bag house operations.

Other types dust collector filter bags are ---
   
    1- Glass fiber Needle Punched Filter Felt
    2 -Poly-P-Phenylene Sulfide(PPS) Needle- Punched Filter Felt
    3-PTFE (Polytetrafluoroethylene) Needle Punched Filter Felt

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.

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.
