High—temperature PPS Needle—punched Filter Felt Bag
High—temperature PPS Needle—punched Filter Felt Bag
PSS fibers have complete strength retention and inherent chemical resistance, which can maintain good filtration performance in harsh environments and achieve ideal service life. It is used to filter coal—fired boilers, garbage incinerators, dust collecting treatment of fly ash in power plants and pulse cleaning dust collectors.

The filter bag is the key component to determine the dust removal efficiency and working temperature of the bag dust collector, and the cost of replacing the filter bag is the main maintenance cost of the bag dust collector. Therefore, the working life of the filter bag is related to the operation state and cost of the dust collector, so it is particularly important to select the appropriate filter material and design the reasonable structure.
The selection of filter material should be considered according to the temperature, humidity and chemical characteristics of the gas, the size, weight, shape, ponderability of particles, dust concentration, filtration speed, ash cleaning mode, emission concentration and the working system of bag dust collector. In general, the pulse spray bag filter uses needle felt, the chamber back blowing bag dust collector or the mechanical vibration bag filter selects the woven cloth.
