PPS dust filter bag is a kind of filter material which is made by PPS fiber (polyphenylene sulfide) through three-dimensional needling. It can be used for a long time at around 160 °C.
The PPS fiber used in the PPS dust filter sock is also called polyphenylene sulfide fiber. Due to its special molecular structure, it has good chemical stability and strength and maintains its characteristics. It is especially effective in the flue gas environment with high sulfur content. It is suitable for high-acid flue gas filtration environment such as coal-fired boilers, electric power, and garbage incineration. The dust filter bag is the heart of the bag filter. During the operation of the bag filter, the cylindrical pulse filter bag is suspended vertically in the dust collector. The dust-containing gas enters the dust collector from the air inlet and passes through the baffle of the ash bucket. Part of the large particle dust in the gas is separated by the inertial force and falls directly into the ash bucket. The dust-containing gas enters the filter bag filtration zone of the tank, and most of the dust is trapped on the outer surface of the filter bag, and is clean. The gas enters the inside of the filter sleeve through the filter material, and the purified gas enters the upper tank through the filter bag mouth, and then is discharged from the air outlet. The cage inside the filter bag is used to support the non woven filter bag to prevent the needle punched filter bag from collapsing, and it helps to remove and redistribute the dust cake.
