The typical parameters:
Dust filter bags

Dust Filter Bags / filter sleeves is the key part of the bag style dust collectors (bag filter houses), which widely used in many industrial occasions for air pollution control, such as cement plants, thermal power plants, food processing plants, pharmaceutical factories, metallurgy plants, fertilizer plants and chemical plants, etc.
Zonel Filtech can provide various dust filter bags for pulse jet bag filter houses and reverse air blown bag filter houses, or some other designed filters.
The dust filter bags from Zonel Filtech are made from various fibers with various finish treatment according to different working condition of the bag filter houses in different industrial occasions.
The sound designed dust filter bags or dust collector bags sometimes we called are very efficient and offer long-lasting excellent functionality and the emission much lower than electrostatic dust filters and always can meet the emission requirements of the clients. The advantages of dust collector filter bags:
1. Low maintenance cost.
2. High filter efficiency.
3. Not affected by the composition of the dust air.

The dust filter bags made of different materials, mainly as following:

A.Acrylic homopolymer dust filter bag:
Acrylic dust filter bags
Acrylic homopolymer dust filter bag are made of acrylic needle felt, which with a mainly advantages of hydorlysis resistant.
Continuous service temperature: 125 degree C.
Instant peaks: 140 degree C.

B.Antistatic dust filter bag :

Some industrial dust will blast once met the static discharge if the flammable and combustible materials' content comes to a certain extent, which will bring the explosion and fire, especial easily to happen when collect the dust in flour mills, chemical plants and coal industies, etc.So in the dedusting application of this case, the dust should be collected with special dust bags which are anti-static.
Zonel Filtech absorbed the advanced technologies and developed the anti-static needle felts and woven cloths which can meet the special demands of the dust collection of blast furnace gas and coal gas in the cement industry, etc.

C. Aramid dust filter bags:
Nomex/aramid filter bags for dust collection
In normal temperature circumstance(under 150 C), the polyester needle felt will satisfy the bag filter systems, if the temperature on the high side, such as tail gas/fume/dust from metallurgical plant, carbon black plant, iron works(blast furnace gas), cement plant (tail gas from cement kiln), petroleum fumes from mixing round the beton and asphaltum, coal fired boiler, etc, the normal filter method won't work. The reason as following:
1. be restricted by specific resistance, the electronic filter system won't works, so the bag filter system is the first choice for dust/fume removal.
2.if the user try to reduce the temperature(made it under 150 C), which will increase the investment and also be restricted by field.
3. just because there may contain some material such as sulfur in the gas/fume, the acid dew will exist. Aramid needle felt, besides equip the ability of spinnability, abrasion resistance, they also with the ability of high temperature resistance, flame resistance, infusibility. The fiber won't self-ignite, when the temperature up to 400 C, the aramid fiber will carbonization gradually. Besides, aramide fiber also with a good dimensional stability, long service life.

D.P84 dust collector bags :
Polyimide/P84 dust filter bags
P84(PI-polyimide) fiber with the properties of high temperature resistance and inflammable, the tri-leaf structure of the fiber help the polyimide needle felt filter cloth with a much lager filter surface when compare to the filter cloth with the other fibers, so the P84 filter cloth is a perfect material and it always can meet very good filter efficiency.
