P84 dust removal filter bag cloth bag

  P84 high temperature resistant needle punched filter felt produced by our company is inspec fibers polyimide fiber produced by Lenzing company in Austria
The filter material has the following three remarkable characteristics: 1
Significant temperature resistance, long-term service temperature of 260 ℃, and safe space to cope with shutdown and accidents
2
2
Good chemical resistance
The filtration value of P84 filter bag for acid waste gas and alkaline dust has been confirmed in the waste incineration operation in the past ten years
3
Low backwashing pressure and high elastic desliming cake efficiency , The P84 characteristic is remarkable due to the fineness of the fiber itself, but also because the irregular fiber cross-section increases the fiber surface area to the maximum and provides a lot of micro pores, so that the surface filtration effect is better than the deep filtration
The dust only stays on the surface of the needle punched filter felt and cannot penetrate into the filter felt
Therefore, the backwashing pressure is small, the filter cake springing efficiency is significantly improved, with excellent fine powder collection efficiency and small operating pressure difference P84 is widely used in waste incineration power plants, cement plants, steel plants, coal-fired boilers and other industries
