摘　　要：利用脉冲滤筒除尘器对粒径分布为0．5～5μm的超细粉体进行净化试验。测试了除尘器净化效率、除尘器阻力及过滤风速等主要性能参数。试验结果说明：脉冲滤筒除尘器对于粒径为0．5～5μm的超细粉体，在过滤风速为0．8—1．25m／min时，除尘器阻力小于300Pa；过滤风速为2．8m／min时，阻力小于1200Pa，净化效率达99．9997％。该脉冲滤筒除尘器具有除尘效率高，阻力损失低，节约除尘系统的动力消耗的优点，有利于在超细粉体净化工艺中的应用。Test was made on using a pulse cartridge dust collector to purify 0.5 - 5 μm ultra-fine powder. The main performance parameters of the collector such as its purification efficiency, resistance and filtering wind speed. The test re- sult shows that for 0.5 - 5 μm ultrafine powder, the dust resistance is less than 300 Pa at a filtering wind speed of O. 8 1.25 m/min,and is less than 1 200 Pa at a filtering speed of 2.8 m/min, and the purification efficiency is 99. 999 7%. The pulse cartridge dust collector has advantages of high dusting efficiency, low resistance loss and economized power consumption, benefiting its application in the purification of ultrafine powder.
