摘要： 通过深入认识回转反吹袋式除尘器的清灰机理,提出了反吹风袋式除尘器清灰系统的设计方法.对反吹气流形成的袋内流场进行了理论与实验研究,并在Φ100mm×6000mm的滤袋模型上进行了实验测试.提出了反吹风清灰系统中反吹风流量和压力的确定方法.研究结果表明,滤袋表面过滤形成的粉尘层对反吹风形成径向反吹气流阻力,即气流对粉尘层的剥离力与粉尘剥离率之间具有较好的相关性.

Abstract: A design method was proposed for the rotary blowback bag filter, based on the understanding of its dust cleaning mechanism in depth. The flow field caused by blowback airflow in the bag was investigated theoretically and experimentally, with a test done on the Φ100 mm × 6000 mm model of bag filter and a method presented to determine the flowrate and pressure of blowback airflow. The results showed that the filtered dust cake on the bag filter surface will form a resistance to the radial blowback airflow, i.e., there is a proper correlation between the force resulting from airflow to peel off the dust cake and dust peel-off rate.
