摘要: 袋式除尘是一种高效的除尘技术，对PM2.5具有较高的过滤效率，但是其运行阻力较大，因此，研发高效、低阻过滤材料是解决大气污染问题的关键所在。以耐高温的PPS纤维针刺布为上下层，超细无碱玻纤为中间层，经过超声波粘合或线缝合技术制备了多层复合过滤材料，研究了滤料在容尘状态下的过滤效率、过滤阻力，以及孔径变化。结果表明，该复合滤料的初始阻力低于150 Pa，容尘后对0.2~2 μm的颗粒物的过滤效率达80%以上；随着粉尘的沉积，滤料的过滤效率有了较大提高，对1 μm以上颗粒物的过滤效率可达99.99%以上，对最易透过粒径（MPPS）的过滤效率达95%以上；过滤前后，滤料的孔径分布发生了变化，过滤后滤料出现了1~5 μm的孔径分布。该复合滤料在工业高温粉尘过滤中将会有较好的应用前景。

Abstract: The dust bag is a highly efficient dust removal technology, with high filtration efficiency for PM2.5, but its running resistance is extremely large.To develop high filtration efficiency, a low-resistance filter material is the key to solving air pollution problems.High-temperature resistant PPS-fiber cloth was used as the upper and lower layers, with ultrafine E-glass fiber as an intermediate layer, to prepare a multilayered composite filter material using ultrasonic bonding or suture.The filtration efficiency, filtration resistance, and changes in the pore size of the filters were studied in the dust holding state.The results showed that the resistance of the composite filters was less than 150 Pa and that the filtration efficiency for fine particles (0.2 to 2 μm) was > 80%.With the dust deposition observed, the efficiency of the filters was greatly improved.The filtration efficiency for particles > 1 μm was > 99.99%, and the filtration efficiency for particles of the Most Penetrating Particles Size (MPPS) was>95%.Before and after filtration, the pore size distribution of the filters was different, and the pore size distribution of 1 to 5 μm existed after filtration.Thus, the new filters should have good prospects for use in industrial high-temperature dust filtration.
