Needs For Bag Filter


Bag Filter systems are utilized to separate or accumulating the fine dust in concentrations up to less than 5 mg/Nm3.Gas composition operating temperature, dust levels the air to doth ratio, the category of fuel and the method of operation determine the quality the Bag Filters material that is utilized .Bag Filter India is constructed from porous woven or felted fabrics. The figure of Bag Filter India is as a tube, through which gasses are passed to remove particles or contaminants. Particles or contaminants , much larger than the porous openings within the Bag Filter allow the gas to pass through, however trap the larger contaminant crystals. Bag Filters can be engineered and produced small to quite large, some situations require Bag Filter up to 30 feet long by three or more feet across. Often Bag Filters may be cased with in a supporting back frame or structure. This supporting structure assists Bag Filter to maintain a shape under any functioning circumstances means normal and ext ream working condition. Now a days Bag Filters are available engineered of different materials.

Bag Filter Material:-

The numerous Bag Filters material were prepared by a non woven pilot plant coupled with the needle punching and thermal bounding combination process. The prepared filer cloth were evaluated by the reliability assessment standard for the environmental cleaning dust collection. A new filter bag medium was thermal attached with polyester felt and poly amide nano-sized web. The air permeability of the filter bag media with nano-sized web was largely reduced as compared with the control media. In the analysis of filtration test the filter material with nano-sized web shows more stable filtration behavior and higher collection efficiency than the other.

Features, Advantages and Benefits:-
The general use Bag Filters is manufactured with a multilayer ed  polypropylene, which provides proficient filtration at high flow rates in both low and high viscosity liquids . The bag comes in four nominal micron sizes to satisfy a wide variety of filtration needs. A plastic collar / handle enables for quick and clean filter change outs and is engineered to fit into most existing bag housing. The large amount of surface area provided by the layers of polyolefin media results in high oil holding capacities.

Special Bag Filter:-

A- Multi Layer Bag:-
     
These are produced of one single element and have 2 to 12 layers. With various pore sized cloth selection Bag Filter India can catch particles at different microns and achieve maximum filtration results.

B:- Oil Absorption Bag:-
These are dual goal bag designed to provide nominal particle elimination rating as well as oil removal capabilities. Bag Filters India of this type is produced of single or multiple oil suction polypropylene melt-blown media and Assisted by pre and post non woven Polypropylene layers. It is perfect for removing trace amount of non emulsified Hydrocarbons and critical filtration applications in automatic paint, metal casting , chemical processing and water filtering systems.


C:- Activated Carbon Bag:- Bag Filter of this variety is  also a dual purpose designed bag to provide seventy percent nominal particle removal capacities. It is produced of special single or multiple Activated Carbon Cellulose media and supported by pre and post non woven Polypropylene layers.
