Time : 2023-06-28 Hits : 2

PPS dust removal filter bag has good mechanical and chemical properties, which can maintain good filtration performance in harsh environment and achieve ideal service life. Depending on working conditions, the service life of PPS filter bag ranges from 2 to 4 years. PPS filter bag is an ideal filter material in pulse ash cleaning dust collectors of coal-fired boilers, garbage incinerators, power plants, chemical plants, etc. 1. PPS filter bag has good temperature resistance, melting point 285 ℃, continuous use temperature 190 ℃, instant use temperature 230 ℃. It can be used when the oxygen content is less than 16%. 2. PPS filter bag not only has high temperature resistance, but also has the unique corrosion resistance of PPS filter bag. PPS filter bag is not easy to block the paste bag, the service life is extended, and the maintenance cost is greatly saved by increasing the gas flow, 3. The dominant working temperature of PPS filter bag is 170 ℃, the short-term working temperature is 232 ℃, the dominant melting point of PPS filter bag is 285 ℃, and the limiting oxygen index is 34~35. PPS filter bag has excellent hydrolysis resistance and acid and alkali corrosion resistance, with a pH value range of 1-14. 4. The PPS filter bag can be used when the oxygen content is 15% or less. 5. The sulfur-containing oxide in fuel or flue gas has proved that PPS filter bag is a fiber with strong acid-base corrosion resistance and chemical resistance. 6. Where the flue contains moisture. 7. PPS filter bag has an excellent performance record when the air cloth ratio is as high as 5:1 for online ash removal and 6:1 for offline ash removal under the industrial and mining conditions of 190 ℃ ~232 ℃
