  • To guide the upgrading design of bag filter’s bag from cylindrical to pleated structure, the effects of filter bag length and structure, theoretical face velocity, and permeability on the vertical filtration velocity distribution uniformity of cylindrical and pleated filter bag were compared and analyzed by computational fluid dynamics numerical simulation method. The change of face velocity distribution after changing the cylindrical filter bag into a pleated filter bag with different lengths was analyzed under the condition of constant filter air volume. The results showed that along the length direction of the filter bag, the face velocity distribution of the pleated filter bag was more uneven than that of the same length, the same outer diameter and the same filter air volume cylindrical filter bag, and the uniformity became worse with the increase of the bag length. The face velocity at the upper 1/4 of the pleated filter bag with a bag length of more than 4 m increased rapidly and even exceeded the cylindrical filter bag. With the increase of the theoretical face velocity, the face velocity at the lower part of the pleated filter bag did not change much, but at the upper 1/4, velocity increased rapidly. Therefore, the setting of the theoretical face velocity of the pleated filter bag should not be too high. Under the conditions of this study, it was advisable to be 0.63 m/min below. With the decrease in permeability of the filter bag, the face velocity distribution was more uneven, and the difference along the pleated filter bag was more significant, so the cleaning pressure drop should not be too high. After transforming the cylindrical filter bag with L=8 m into the pleated filter bag with L=5 to 8 m, the longer the filter bag, the smaller the theoretical face velocity, but the worse the uniformity of the face velocity. Considering these two factors, face velocity and uniformity, it was recommended to be 7 m under the conditions of this study.
