脉冲滤筒除尘器对超细粉体净化的实验研究

随着工业的快速发展,空气中颗粒污染物的含量和种类越来越多,不仅对人体健康造成危害,颗粒污染还对能见度、气候、动植物均有影响,寻找合适的除尘设备,提高对微细粉尘的除尘效率,对安全和环境保护有着重要而深远的意义。该文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实验。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。实验结果说明:脉冲滤筒除尘器对于粒径为0.5-5μm超细粉体,在过滤风速为0.8-1.25m/min时,除尘器阻力小于300Pa,净化效率达99.9999%。得到结论:滤筒除尘器具有高除尘效率,低阻力损失,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。

Experimental study on ultra-fine powder purification of pulse-jet cartridge dust collector

With fast development of the Industry, more and more content and species of particulate pollutants are in the air. The particulate pollutants not only cause harm to the human health, but also have negative effect on the visibility,the climate ,animals and plants. So it is important to safety and environmental protection that finding suitable dust collecting equipments and raising dust removal efficiency of fine dust particles.
This paper was on the use of the pulsejet cartridge dust collector to do the purifying experiment of the ultrafine powder. The experimental tested the main characters of the pulsejet cartridge dust collector, such as the purifying efficiency, the dust resistance and the filtering speed. The experimental results were that this study was used by the pulse- et cartridge dust collector to purify 0.51μm - 51μm ultra-fine powders, tested the filtering speed were 0.8 m/min-1.25m/min, dust resistance was less than 300Pa and the purifying efficiency was 99. 9999%. At last, it comes to a conclusion： the pulse-jet cartridge filters are with the advantages of high efficiency, low pressure drop and save power to the dust removal system. The pulse-jet cartridge f dust collectors are in favor of ultra-fine powders purifying technology.
