分室反吹式清灰办法的袋式除尘器是选用分室结构、阀门逐室切换、构成逆向气流,矿山布袋除尘器迫使滤袋缩短或鼓胀而清灰。这种清灰办法也属于低动能型清灰,借助于袋式除尘器的作业压力作为清灰动力,在特别场合下才另配反吹气流动力。分室反吹式清灰办法的袋式除尘器要求选用质地柔软、简单变形而尺寸安稳的薄型滤布,因该袋式除尘器有内滤与外滤之分,故滤布的选用略有差异。一般来说,内滤式常用圆形袋,无结构,袋径为120~300mm,袋长与袋径比为15~40,优先选用缎纹(或斜纹)机织滤布,厚1.0~1.5mm,单位面积质量为300~400g/m2;外滤式常用扁形袋、菱形袋和蜂窝形袋,带支撑结构,优先选用耐磨性、透气性较好的薄型针刺毡滤布,单位面积为350~400g/m2。

振荡反吹并用式清灰办法的袋式除尘器是指兼有振荡和逆气流两层清灰效果的袋式除尘器,矿山布袋除尘器其振荡使尘饼松动、逆气流使粉尘脱离。两种办法相互配合,使清灰效果得以进步,特别适用于细颗粒粘性粉尘的过滤。此类袋式除尘的滤布选用,大体上与分室反吹式清灰办法的袋式除尘器相同。
