水泥仓顶除尘器工作原理

 含尘气体由进风口进入除尘器箱体内,细小尘粒由于布袋的多种效应作用,被滞阻在布袋外壁。净化后的气体通过布袋上箱体出风口排出。随着使用时间的增长,布袋表面吸附的粉尘增多,布袋的透气性减弱,使除尘器阻力不断增大。为保证除尘器的阻力控制在限定的范围之内,由脉冲控制仪发出信号,循序打开电磁脉冲阀,使气包内的压缩空气由喷吹管各喷孔喷射到对应的文氏管(称为一次风),并在高速气流通过文氏管时诱导数倍于一次风的周围空气(称为二次风)进入滤筒,造成布袋间急剧膨胀,由于反向脉冲气流的冲击作用很快消失,布袋又急剧收缩,这样使积附在布袋外壁上的粉尘被清除,落下的灰尘进入灰库。

仓顶布袋除尘器特点
 a、仓顶除尘器体机小、风速大、噪音小、低能耗、维护费用低。
 b、仓顶除尘器纤维滤袋易清洗、阻拦细小的粉尘颗粒、废气,滤袋更换率低。
 c、仓顶除尘器采用脉冲清灰方式,延长喷吹时间,降低能耗,增加配件寿命。
水泥仓顶除尘器主要适用于仓顶、各种库顶、库底机械设备、各种输送设备等排放和扬尘点的收尘
