Dust Collector Filter Bags are important component of a filtration system. These are made from glass fiber , acrylic , polyester, polypropylene, PTFE, P84 and nomex etc. These pleated dust collection bags are very efficient and present long-lasting excellent functionality. These pleated dust collection bags are widely employed for pollution control. Dust collector filter bags are also employed in metallurgy, fertilizers and chemical manufacturing plants.
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 other harmful things can not be permitted to exhaust in open environment. Plant of these categories implement dust collector filter bags to collect dust and other harmful elements. There are a variety of manufacturing techniques to manufacture suitable dust collector filter bags to fulfill all the requirements of a dust collector depending up on the system of cleaning such as pulse & reverse jet and auto mechanism cleaning.
Advantages of Dust Collector Filter Bags-
1- Its preservation cost is low.
2-Practical efficiency of Dust Collector Filter Bags are incredibly high.
3-It recovers heat very proficiently.
4-It is effective and not affected by Gas-dust composition
Dust collector filter bags perform a key role in these kinds of production plants who also make dust and other unsafe chemical crystals with their consumer goods. These manufacturing plants are like cement, thermal power station, fertilizers,steel pants , aluminum , zinc , lead , asbestos and chemical plants etc. Dust collector filter bags are applied here to collect harmful and dust substances.
The Secondary function of the dust collector bags is to control 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 responsible to maintain sucked crystals and enable the air to pass. In all the stages of cement manufacturing , dust collector filter bags are proved to be the best because of its high-efficiency and flow rate etc. Dust collector filter bags may operate proficiently during working in different temperatures,which may vary in accordance to the process of production dry or wet in industries 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 available in woven or felt form. This product offers chemical resistance identical 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 delivers good chemical resistance to acid and alkalis.
It is employed in chemical processing .
It is utilised in mineral processing.
It is applied in metal processing.
B-Antistatic Needle- Punched Filter Cloth-
MS Anti static needle punched filter cloth simply results in the explosion and conflagration after the consistency of common commercial power and dust reaches certain degree. It is handling the static electricity light and spark outside such as flour powder, coal powder and chemical crystals. To hold 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 other features 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 high heat -proof filter material good chemical -proof, good air permeability and high filtration efficiency. It is mostly utilized in coal boilers of thermal power stations.
E- Polyester (PET) Needle Punched Filter Felt-
MS Polyester needle punched filter felt offer a cost-effective alternative for a number of industrial operations. They are highly versatile and efficient in dust collection.
F- Water and Oil Resistant Filter Cloth-
After oil and water handling several filter fabrics can form a layer of substances obstacle around the fiber surface. This style of dust collector filter bags filters different pollutants from the water and oil.
G- Filter Bags with PTFE Membrane Laminating-
These dust collector filer bags are employed 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 kind of dust collector filter bags engineers can reduce capital and operational costs. Use of this type of dust collector filer bags also provide 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
Dust Collector Filter Bags is a standards product of Amrit Filtration Equipments, which is a well-known manufacturer and supplier of Dust Collector Filter Bags. The author is presently working on the designation of specialist of Dust Collector Filter Bags.
