China Dust removal needle punched non-woven filter bag PTFE filter bag
1. PTFE dust filter bag introduction
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.
1) Excellent temperature resistance, reaching 280 degrees.
2) Due to the special molecular structure of PTFE material, it has excellent chemical stability and corrosion resistance, which can improve the chemical erosion of the filter material.
3) Due to the non-sticky, water-repellent and non-flammable characteristics of PTFE fiber materials, this type of fiber becomes the most excellent filter material.
4) This kind of fiber is used as the base cloth, and the strength is basically guaranteed not to be attenuated during long-term use
Fiber shape: Because of the different spinning methods, the fiber color is divided into white and brown. The white fiber is relatively pure, and the fiber shape is mostly flat, while the brown fiber contains a small amount of impurities, and the fiber shape is mostly round.
The C-C bond is covered by the F atom in the PTFE molecule, and the C-F bond has a high and extremely stable bond. It is not corroded by any chemicals except for alkali metals and fluorine.
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℃.

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. How to pack the Waste Incineration Dust Collector PTFE Filter Bags?
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
