Abstract: With the wide application of bag filters in the industry, the treatment of a large number of waste filter bags has become an urgent environmental problem. Through experiments, the method of cleaning and reuse of bag filter materials was explored, and the effects of AMES(α-sulfonyl fatty acid methyl ester sodium) cleaning agent concentration, cleaning time and cleaning temperature on the cleaning effect and service performance of filter materials were studied, which not only realized circular economy but also reduced the operation cost of bag dust removal. The results showed that the optimized running condition was as follows:the cleaning temperature was 40℃, the waste polyphenylene sulfide filter material was put into AMES solution with a mass concentration of 2.5%, the self-designed rolling cleaning machine was used for cleaning for 20 min, and cleaning in ultrasonic cleaning machine was for 10 min. The cleanliness of 95.82%, filtration performance of efficiency for 0.3,0.5,1.0,2.5, 5.0,10.0 μm increased by 81.09%, 86.33%, 94.86%, 98.58%, 99.28%, 99.31%, and air permeability of the filter material of 8.182 m³/(m²·min) were the best, and the cleaning process had no obvious impact on the mechanical properties of the filter material.
