Dust collector bag material PPS high temperature resistant dust removal filter bag Product introduction:
bag filterDue to the different materials used in use, their temperature resistance and characteristics are also different. The high-temperature resistant PPS dust bag has a temperature resistance between 170 ℃ and 190 ℃. PPS (polyphenylene sulfide) high-temperature resistant dust bag (filter bag) is divided into two types based on the use of raw materials: domestic fibers and imported fibers. Currently, domestic PPS fibers are almost the same as imported Japanese Toray PPS fibers, but the fiber strength is weaker. Under the same working conditions, the service life is reduced by about 10-25%; At present, PPS needle punched filter felt on the market is divided into two types: 500g/㎡ and 550g/㎡, with an error of ± 5% g/㎡. Due to the poor hydrolysis resistance of PPS fibers, waterproof treatment must be carried out. Qualified PPS dust removal bags for coal-fired boilers meet the new national GB/T6719-2009 standard in terms of technical quality assurance. To cope with stricter dust emission concentration requirements, PPS coated dust removal bags for coal-fired boilers stand out when the required dust emission concentration is below 10 milligrams.
The PPS coated dust removal bag for coal-fired boilers has significantly improved strength, antioxidant performance, and hydrolysis resistance compared to ordinary PPS filter media. PTFE protective film is formed on the fiber surface and intersection points, which enhances the adhesion between fibers and improves the antioxidant, hydrolysis, and corrosion resistance of PPS fibers to sulfur-containing gases, alleviating other performance aging. Due to the coverage of microporous film on the surface of the filter material, the filtration accuracy and performance are significantly improved. After treatment such as drying and heat setting, the high-temperature dimensional stability is enhanced. If dust removal bags are distinguished by temperature, bag dust collectors can be divided into three categories: A, bag dust collectors that handle ambient temperature dust. B、 Bag filter for handling medium temperature dust. C、 Bag filter for handling high-temperature dust. So how are these three temperatures distinguished? Generally, the medium temperature resistance is between 130-180 degrees Celsius, the high temperature is between 180-280 degrees Celsius, and the low temperature is below 130 degrees Celsius.
