Dust filter bags
Dust Filter Bags/filter sleeves is the key part of the bag style dust collectors (bag filter houses), which are 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 treatments according to different working conditions 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 is 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 are made of different materials, mainly as follows:

A.Acrylic homopolymer dust filter bag:

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

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 :

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.

E.Polyester (PET) dust filter bags :

F.Water and Oil Resistant dust collector bags:

After water-oil repelled treatment, the filter bags can be use in the circumstance of moisture and oil mist for a long time, so which is not easy to be blocked even if there is any dew points in the bag filter house.

G.Filter Bags with PTFE Membrane laminated.

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 form of dust collector filter bags engineers can reduce capital and operational costs. Use of this style 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.

H.Glass fiber / FMS filter bags:

Fiber glass needle punched felt is a reasonably new type of filter media used for fiber bags in high-temperature circumstance, with the properties of three-dimensional cellular structure, a high hold rate, and low air resistance, the filter efficiency will be superior than woven filter fabrics can up to 99.9%, with a high filter velocity will the two times when compared with other normal woven filter fabrics, this fabrics widely used in carbon plant, chemical plant, metallurgical plant, coal fired boiler, etc. Fiber glass needle felt applicable to the pulse jet bag filter system, high temperature and corrosion resistance, with good performance for manage the industrial dust pollution, and recycle the valuable particles.

General introduction of the Polyimide (P84, PI) needle-felt filter cloth:
When the temperature of the dust air is more than 250 degrees C and the dust can not be collected through ESP, then as usual we have to reduce the temperature of the dust air and make it possible to be purified through bag-type dust collectors, but the investment will increase much when this happen.

Due to the fiber glass is fragile and PTFE fiber with a higher heat shrinkage and weak cohesion, to meet the high filter efficiency, both of them need to be laminated with PTFE membrane, which will increase the resistance of the bag filter houses and lower the air/cloth ratio of course, so the polyimide filter cloth (can be P84 filter cloth, PI needle felt, Yilun filter cloth) will become to the first option to make it into high-temperature resistance filter bags.
