【摘要】 在湿式除尘中,雾化除尘技术已被证明可以有效提高装置的除尘效率.采用超声波雾化加湿技术,强化袋式除尘器的过滤性能,以PTFE覆膜滤料为过滤介质进行实验.实验证明,超声波雾化可以延长袋式除尘器的单次过滤时间,降低反清洗频率,但是对袋式除尘器的除尘效率影响较小.更多还原

【Abstract】 Vapor heterogeneous condensation on the surfaces of Micro-sized particles could be used to increase the removal efficiency of Micro-sized particles from gas in wet-scrubber.An filtration experiment device in which filtration media was superseded by PTFE was set up to investigate the influence of ultrasonic atomizer,which provided vapor by ultrasonic wave,to the removal efficiency.The results show that the collection of Micro-sized particles was unchanged with the addition of vapor in bag filter,while the frequency of back flushing was availably decreased by 93%.更多还原
