PPS needle felt is a kind of filter material made of PPS fiber (polyphenylene sulfide) through three-dimensional acupuncture, which can be used for a long time at 160 ℃. PPS fiber, also known as polyphenylene sulfide fiber, has good chemical stability and integrity of strength due to its special molecular structure. It is especially effective in the flue gas environment with high sulfur content, and is suitable for the flue gas filtration environment with high acidity such as coal-fired boiler, power, waste incineration and so on.

The dust filter bag is the heart of the bag type dust remover during operation. Generally, the cylindrical pulse filter bag is suspended vertically in the dust collector. The dust containing gas enters the dust collector from the air inlet, passes through the guide plate of the ash hopper, so that part of the large particles of the gas are separated from the filter area by the inertia force, and directly fall into the ash hopper, and the dust containing gas enters the filter area of the PPS filter bag of the box. Most of the dust is arrested on the outer surface of the PPS filter bag, while the clean gas enters the inside of the PPS filter bag through the filter material. The purified gas enters the upper box through the PPS filter bag mouth, and then it is discharged by the air outlet. The cage inside the PPS filter bag is used to support the PPS filter bag to prevent the PPS filter bag from collapsing, and it helps to remove and redistribute the dust cake.
