滤筒除尘器的 原理介绍 HOW DOES IT WORK
含尘气体从风口进入灰斗后，一部分较粗尘粒和凝聚的尘团，由于惯性作用直接落下，起到预收尘的作用。进入灰斗的气流折转向上涌入箱体，当通过脉冲褶皱滤筒时，粉尘被阻留在滤筒的外表面。净化后的气体进入滤筒上部的清洁室汇集到出风管排出。除尘器的清灰由脉冲电磁阀及控制仪完成，合理的清灰确保滤筒的使用寿命。除尘器工作时，随着过滤的不断进行，滤筒外表的积尘逐渐增多，除尘器的阻力亦逐渐增加。当达到设定值时，清灰控制器发出清灰指令，将滤筒表面的粉尘下来，并落入灰斗，整个过程为过滤、脉冲清灰、出风。
From the inlet,the big dust and dust ball will fall into the hopper for sake of the inertia force ,that is called pre-filter.The air flow in the hopper then upflows into the filter room and the rest dust is filtered on the surface of the filter cartridges.The clean air goes into clear room and discharges from the outlet.Pulse solenoid valve and controller are the dust collector’s dust-cleaning.Setting proper pulse cycle will prolongs the service life of the filter cartridge.During working time,time after time of gilter,the dust on the surface of the cartridge gradually increases,so does the resistance of the dust collector.When the resistance reaches the setting limit,the controller then start the process of dust-cleaning.The dust on the surface of the filter cartridge will fall into the hopper,this whole process called filter,pulse dust-cleaning and outlet.
