以滑石粉作为试验粉尘，以1#、3#中空纤维滤料作为过滤介质，对高效纤维过滤器的性能进行了研究。采用均匀设计法考察了气体含尘浓度、过滤风速、滤料压缩率和过滤时间四个因素对过滤器阻力降和过滤效率的影响。利用DPS数据回归处理方法建立数学模型，确定出试验范围内的优化工艺条件：对于1#滤料，在气体含尘浓度0.68 g/m3，过滤风速0.5 m/s，滤料压缩率16.7%，过滤时间10.3 min 时，阻力降为172 Pa，过滤效率为99.993%；对于3#滤料，在气体含尘浓度0.5 g/m3，过滤风速0.5 m/s，滤料压缩率15.4%，过滤时间3 min时，阻力降为493 Pa，过滤效率为99.992%。

The filtration performance of fibrous filtrator was studied by using talcum powder as test dust and hollow fiber materials named 1# and 3# as filter medium. The influence of dust concentration of gas, velocity of filtering, compression ratio of filter material and filtration time on pressure drop and filter efficiency was studied by using uniform design method. Regression analysis was used to establish a mathematical model by DPS and the optimum conditions were obtained. For the fiber material of 1#, when dust concentration of gas was 0.68 g/m 3, velocity of filtering was 0.5 m/s, compression ratio of filter material was 16.7% and filtration time was 10.3 min, its pressure drop was 172 Pa and its filter efficiency was 99.993%. For the fiber material of 3#, when dust concentration of gas was 0.5 g/m3, velocity of filtering was 0.5 m/s, compression ratio of filter material was 15.4% and filtration time was 3 min, its pressure drop was 493 Pa and its filter efficiency was 99.992%.
