Dust filter bags

Factory direct sale New Custom High Temperature Resistant PTFE Laminating Dust Collector Filter Bags

There are many raised fluffs on the surface of the fiber felt dust filter bag cloth after needle punching. The purpose of singeing is to burn off the fluff on the surface of the fiber baghouse filter felt. When singeing, the needled bag filter fiber felt is smoothly and quickly passed through the high-temperature flame or wiped across the hot metal surface. At this time, the raised fluff on the surface of the needled punched filter media felt quickly heats up and burns or melts, while the body of the needled felt is relatively dense. The temperature rises slowly. Before reaching the ignition point, it has left the flame or hot metal surface, so as to achieve the purpose of burning off the fluff without damaging the body.

1. The influence of the moisture content in the air on the PTFE dust filter bag

When the moisture content in the air is constant and the temperature of the humid air is lower than the dew point temperature, moisture will precipitate in the supersaturated air, that is, condensation will occur in the dust bag; when the air temperature is higher than the dew point, no moisture will be precipitated. There will be no condensation. In addition, if the flue gas contains SO2, the more SO2 content, the higher the dew point of the flue gas


2.Measures to extend the life of filter bags

1. Appropriate filtering wind speed

Generally, when the dust concentration is high, the wind speed of the filter should be lower, and vice versa. The smaller the dust particles, the lower the wind speed of the filter, and vice versa.

2. Pre-spray to prevent oil adhesion

When the boiler is ignited and operating under low load, it usually takes a long time to drain the oil. If the filter bag is not pre-treated when the oil fume passes through the filter bag, it will cause irreversible damage to the filter bag.

3. Correct injection pressure and pulse width

Adjust the appropriate blowing pressure and pulse width to avoid excessive blowing pressure.

4. Suitable exhaust temperature

Strictly control the change of exhaust temperature to prevent it from being too high or too low.

5. Temperature indicators

The filter material can be divided into normal temperature filter material, medium temperature filter material and high temperature filter material according to the amount of temperature it withstands. Generally speaking, the high temperature that can withstand is about 200~300, and the temperature tolerance of the glass fiber filter material is 300, but the working temperature should be controlled at about 260.

5. Application field:

Yuanchen products are widely used in purifying dusty air in industries like Metallurgy, Steel, Cement, Mechanical, Electricity, Chemicals, Waste Incineration, Concrete Mixing and Other conditions of complex industries.
Yuanchen pulse jet dust Filter Bags are sold very well both domestic and abroad, highly praised by our customers.
We can supply you with the product in large quantity at wholesale prices.
And best after-sales service provided after order confirmed.

6. The Asphalt Plant Dust Collector Aramid PTFE Filter Bags packaging:

Different types of dust collection filter bags must be individually packaged. In general, it is wrapped in plastic bags for water proof, then put in a carton. Dust Bag Filter must be neat and regular packing, with the ring of the waste incineration dust filter bag to avoid ring flat compression deformation. For the requirement to keep the shape of cloth dust collector filter bag, it must fill padding for filter bag inside. Any other packing ways also be accepted up to you.



7.Advantages 

1.careful lathe stitching-the lathe sealing edge three locks,not off-line line

2.high quality material-the fiber has high strength,high stability and high heat resistance

3.sweet custom-can be customized,can be coated,high temperature resistance

4.thickness is optional-different thickness can be made according to customer's requirements

P84 Dust Filter Cloth
Dust Collector P84 Filtering Material
Long-term temperature resistance 230℃, instantaneous temperature resistance 260℃; It is made of a polycondensation polymer, which is not resistant to hydrolysis; the cross section is in the shape of a trilobe. Due to the increased surface area of the single fiber, it can effectively trap particles, and the filtration accuracy is high; It is a non-thermoplastic fiber, and has stronger abrasion resistance to pulse cleaning than glass fiber. Therefore, P84 can be used instead of glass fiber or mixed use under conditions that require good abrasion resistance. Its anti-oxidation performance is better than PPS filter media, but its acid resistance and hydrolysis resistance are slightly worse, and its alkali resistance is poor. It is suitable for use in the treatment of kiln flue gas with low sulfur content.
