Features-of Dust Collector-filter-bags In Industries
Dust Collector Filter Bags are important part of a filtration system
. These are made out of glass fiber, acrylic, polyester, polypropylene, PTFE, P84 and nomex etc. These pleated dust collection bags are very efficient and produce long-lasting excellent efficiency. These pleated dust collection bags are generally employed for air pollution control. Dust collector filter bags are also implemented in metallurgy, fertilizers and chemical manufacturing plants.
These are essentially required where the dust is produced throughout processing materials. For instance flour mill, pharmaceutical factories food processing etc, where the dust and other unsafe things can not be allowed to exhaust in open environment. Plant of these varieties use dust collector filter bags to collect dust and some other harmful things. There are a number of manufacturing techniques to manufacture appropriate dust collector filter bags to meet all the prerequisites 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 servicing cost is low.
2-Practical effectiveness of Dust Collector Filter Bags is high.
3-It recovers heat very proficiently.
4-It is effective and not affected by Gas-dust composition
Dust collector filter bags act a vital role in these types of manufacturing plants who also generate dust and different unsafe chemical crystals with their consumer goods. These production plants are such as cement, thermal power station, fertilizers, steel pants, aluminum, zinc, lead, asbestos and chemical plants etc. Dust collector filter bags are used here to collect harmful and dust crystals.
The Secondary purpose 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 carries these elements inside the dust collector. Dust collector transmits the air into the dust collector filter bags. Here dust collector filter bags are responsible to hold sucked crystals and enable the air to pass. In all the stages of cement production, dust collector filter bags are proved to be the best because of its high-efficiency and flow rate etc. Dust collector filter bags may perform efficiently during working in different temperatures, which may differ in accordance to the process of manufacturing 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 provided in woven or felt form. This product presents chemical resistance identical to poly propylene while allowing operation up to 250 degree Fahrenheit (equivalent to 121 c).
Its characteristic is a great combination of filtration efficiency and dust layer release.
It offers good chemical resistance to acid and alkalis.
It is implemented in chemical processing.
It is applied in mineral processing.
It is implemented 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 professional power and dust reaches certain degree. It is handling the static electricity light and sparks outside such as flour powder, coal powder and chemical elements. To include 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 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 repellent filter material good chemical proof, good air permeability and high filtration performance. It is mostly applied in coal boilers of thermal power stations.
E- Polyester (PET) Needle Punched Filter Felt-
MS Polyester needle punched filter felt deliver a cost-effective solution for many industrial activities. They are highly adaptable and efficient in dust collection.
F- Water and Oil Resistant Filter Cloth-
After oil and water handling various filter fabrics can form a layer of molecules obstacle around the fiber surface. This type 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 utilized 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 form of dust collector filer bags also deliver 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
