摘要: 利用脉冲滤筒除尘器对粒径分布为0.5~5 μm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0.5~5 μm的超细粉体,在过滤风速为0.8~1.25 m/min时,除尘器阻力小于300 Pa;过滤风速为2.8 m/min时,阻力小于1 200 Pa,净化效率达99.999 7%。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。

Abstract: Test was made on using a pulse cartridge dust collector to purify 0.5~5 μm ultrafine powder.The main performance parameters of the collector such as its purification efficiency, resistance and filtering wind speed.The test result shows that for 0.5~5 μm ultrafine powder, the dust resistance is less than 300 Pa at a filtering wind speed of 0.8~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.
