We examined the effect of pleat shape and length of cartridge filter on the dust removal performance. By introducing the parameter taking account of installation space, we found that the existence of optimum design point of P / H (ratio of pleats pitch P to height H) ranged from 0.15 to 0.25. Moreover, the removal performance tests for the various length of the cartridge revealed that the amount of gas under the same pressure drop was not proportional to the length of the cartridge. From concerning accessing the amount of gas processed per unit volume of equipment, it was found that optimum length exist and it depends on the pulse air consumption. In addition, we examined the effects of the distance between pulse jet nozzle and the top of cartridge filter Hp and the inner cylinders diameter of the cartridge filter D on the dust removal performance. We found that the existence of optimum design point of D / Hp was in 0.4 - 0.5 for cartridge length 540 mm, air pressure 0.5 MPa, air consumption 4.5 LN / piece.
