| The research on the performance of Polysulfonamide fiber and filtration medium. As the filter media if the heart of bag house, In this paper, its smoke industrial furnace is analyzed, the oxidation resistance, high temperature flue. This requires the filter material products, can adapt high temperatures complex working condition. At present, the filter material in China and abroad by high temperature fiber are PPS, glass fiber and PTFE. This paper analyzed the characteristics of these fibers, PPS cannot long used in high temperature environment. And untreated fiber glass also cannot be used in high temperature flue gas purification. If using a pure PTFE fiber filter material, the price is very high, coated filter material about 2-3 times. The currently used in high temperature flue gas processing fabric are mostly glass fiber coated (PTFE membrane) filter material, but because PTFE membrane filter material is very thin, very easy to fall under the environment of high temperature, lower filter material using life. New filters the material is in the summary enhances, abandons the shortcoming which as well as in the consideration performance-to-price ratio foundation the tradition filters foresees accurately researches and develops. On the analysis of the polysulfonamide fiber basic performance and industrial furnaces high temperature fume, on the basis of the basic characteristics of polysulfonamide fiber produced by the filter material and the compound filter material heat-resistant performance and filtering performance testing research. The result indicated that after the fragrant sulphone black silk ribbon compound filters the material process heat treatment intensity maintenance rate to surpass other to filter the material, size stability good break force maintenance rate is in turn the PSA+fiberglass composite filter pure PSA to filter the material, the fragrant black silk ribbon to filter the material. Fine particulate performance in filtration, pure PSA test liao, PSA coated fabric and PSA+fiberglass composite filter clean and dust collection state in the classification efficiency, and made the contrast. The analysis result indicated:Filters the material filtration stage efficiency and the particle size criterion basic present compares the relations; Under the collection dust condition's stage efficiency is higher than under the clean condition the stage efficiency; When filters the material trapping efficiency close 100%, the PSA membrana tectoria filters the material,100%PSA to filter the material, the PSA+ fiberglass filament to filter the material this time to trap the grade respectively is: 0.6μm,0.8μm,6μm. As a whole, the fragrant sulphone black silk ribbon different compound filters the material filtration stage efficiency is in turn from high to low: The PSA membrana tectoria filters the material,100%PSA to filter the material, the PSA+fiberglass filament compound to filter the material.As the actual project's application, the paper gave back has used the fragrant sulphone black silk ribbon textile fiber and the glass fiber the two mix manufacture compound filters the material, the success uses in the metallurgy extinguishing the coke oven haze dust removal case dry.Through to the PSA filter material and the PSA compound filter material experiment research get: the PSA compound filter materials, it can be used for industrial furnaces, high-temperature smoke dedusting heat-resistant property of advantage, has some prominent in the efficiency of filtering needs to improve.
