    1、机械摇动清灰

    在清灰时先关闭除尘风机,然后通过一台摇动电机的往复摇动给滤袋一个轴线方向的往复力,滤袋又将这一往复力转换成径向的抖动运动,使附在滤袋上的粉尘下落。

    这种清灰方法的除尘器结构简单、性能稳定,适合小风量、低浓度和分散的扬尘点的除尘,但不适合除尘器连续长时间工作的场合。

    2、逆气流反吹清灰

    分室反吹式清灰

    采用分室结构、阀门逐室切换、形成逆向气流,迫使除尘布袋收缩或鼓胀而清灰。这种清灰方法也属于低动能型清灰,借助于袋式除尘器的工作压力作为清灰动力,在特殊场合下才另配反吹气流动力。

    振动反吹并用式清灰

    兼有振动和逆气流双重清灰作用的袋式除尘器,其振动使尘饼松动、逆气流使粉尘脱离。两种方式相互配合,使清灰效果得以提高,尤其适用于细颗粒粘性粉尘的过滤。此类袋式除尘的滤料选用,大体上与分室反吹式清灰方式的袋式除尘器相同。

    喷嘴反吹式清灰

    利用高压风机或鼓风机作为反吹清灰动力,通过移动喷嘴依次对滤袋喷吹,形成强烈反向气流,使滤袋急剧变形而清灰,属中等能量清灰类型,按喷嘴形式及其移动轨迹可分为回转反吹式、往复反吹式和气环滑动反吹式等三种。

    回转反吹式和往复反吹式清灰

    清灰时从相反方向反吹空气通过滤袋和粉尘层,利用气流使粉尘从滤袋上脱落。采用气流清灰时,滤袋内   支撑结构,如撑环或网架,以避免把滤袋压扁、粘连,破坏初层。

    3、MAICHONGPENCHUIQINGHUI

    利用脉冲喷吹机构在瞬间释放压缩气流以压缩空气为动力,通过文氏管诱导周围数倍的二次空气在极短的时间内喷入除尘布袋,使除尘布袋由过滤状态向中心收缩状向外鼓起变形、振动急剧变形,粉尘脱离除尘布袋表面被抖落入灰斗。
