P84 dust filter bag is also called polyimide dust filter bag, which is a commonly used filter bag in the field of high temperature dust removal. P84, commonly known as polyimide, is a high-temperature-resistant synthetic fiber made of polycondensation polymers. The cross-section of the fiber is trilobate-shaped, which effectively increases the filtration area and provides a medium that can effectively trap particles. The effect is remarkable. At present, it is suitable for coal-fired boilers, liquid bed boilers, waste incineration, asphalt plants, cement plants, steel, metallurgical carbon black, waste incinerators, etc.
The application condition of p84 filter bag is a flame-retardant, heat-resistant and stable synthetic fiber filter system. Under the temperature specification of 240°C, the industrial equipment of the P84 polyfluorobenzene synthetic fiber filter system is not easy to change. Heat resistance up to 260°C. P84 synthetic fiber filter system has no melting point temperature, natural bridge yellow. P84 polyfluorophenylene synthetic fiber filter system is not a synthetic fiber filter system with high water absorption capacity (at 65% relative humidity standard, it is about 3% moisture absorption capacity). Main parameters of p84 filter bag In addition, because P84 synthetic fiber has a special-shaped (leaf-shaped) cross-sectional structure, it has a very large filtration area and excellent filtration characteristics, so P84 synthetic fiber is often placed on the surface of other dust collector bags. (Facing the dust side to improve the filtration characteristics of the filtration system). For example, P84 synthetic fiber is mixed with a very high percentage of P84 synthetic fiber in the special-purpose Flumes filter bag for blast furnace gas dust collector equipment, in order to improve the filtering effect and high temperature and corrosion resistance. The characteristics of the P84 dust collector bag are obvious due to the particle size distribution of the synthetic fiber itself, and because the irregular cross-section of the synthetic fiber increases the total area of the synthetic fiber to a large extent and provides a lot of small porosity so that the surface filtration effect is better than that of the deep filter. Hierarchical filtering. The dust only stays on the surface of the filter felt filter bag and cannot penetrate into the filter felt, so the backwash pressure is low and the anaerobic fermentation granular sludge has a high ejection efficiency, which has been significantly improved, and has a good fine powder collection efficiency. The pressure difference is small. P84 aluminum silicate needle felt dust collector bag is a high-end high temperature resistant filter bag type that can be compared with PTFE aluminum silicate needle felt dust collector bag, and even its filtration efficiency and dust removal effect are higher than PTFE silicic acid Aluminum needle felt dust collector bag.

The main advantages and features:
1. To increase system filtration capacity by 50-150% as needed without major changes to the dust collectors ;
2. System cleaning efficiency markedly increased with the effective increase of bag to bag distance;
3. Bag life extended due to significant reduction of fatigue damage to the bags due to bag to cage impact.
