滤筒知识1
点击次数:2022次    发布时间:2020-08-17

       DFC 滤筒是由一定长度的滤料折叠成褶,首尾粘合而成的过滤筒。滤筒无笼骨,安装简便。滤筒的品种较多,有细而长与粗而短之分。细长滤筒(如φ≤160,L=1~2m),其褶(如45褶)间空隙大、夹角大,褶少而浅,过滤面积比同径同长的滤袋大2~5倍,清灰易而效果好;适用于浓度≥15g/m粉尘的过滤除尘,过滤风速0.6~1.2m/min。粗短滤筒(如φ350,L=0.66m)直径大、长度短、褶多(120~350褶)而深、褶间空隙小,过滤面积大,较之同径同长滤袋面积大14~35倍,适于场地面积小、空间小的地方布置;但因褶角小,粉尘易积聚,难于清灰,适于浓度≤5g/m粉尘的过滤除尘,过滤风速不宜>0.6m/min。
       滤筒脉冲除尘器的安装方式有三种:垂直、倾斜、水平安装。滤筒垂直安装,脉冲清灰时,粉尘易清落沉降至灰斗,效果好。倾斜安装时,滤筒上下相叠,结构紧凑,占地面积小,便于换筒,但清灰时,上层滤筒清落的粉尘沉落于下层滤筒上,难以清除。水平安装,下层滤筒上部的粉尘更难清除。倾斜安装滤筒除尘器适于中小除尘系统非粘性、低浓度、粒粗粉尘除尘用,也适于一些老式袋除尘器的改造用。
