根据性价比选用合适的布袋数量，（仓内选用直径15cm的滤袋192个）在保证达到预期环境效益及保证岗位工工作环境良好的情况下，滤筒除尘器尽量节约成本。在集尘罩远离下料口的一端开一个回收煤粉管道，经过脉冲袋式除尘器后收集的烟尘通过刮板机刮到管道中回收利用，滤筒除尘器在除(chu)尘器干管上开清扫孔，防止粉尘沉积将(jiang)管道堵塞。

烟囱冒灰的主要原因及排除方法：过滤袋渗露：更换如果滤袋撕裂或有小洞。检查弹簧圈的安装，确保紧密。花板渗露：填隙或焊缝。滤筒除尘器无(wu)足够尘(chen)饼(bing)：降低压缩空气压力；减少清灰(hui)频(pin)率/喷入中(zhong)性调制粉以产生初(chu)级尘(chen)饼(bing)。滤(lv)袋或(huo)滤(lv)筒(tong)(tong)过多气孔：滤(lv)袋或(huo)滤(lv)筒(tong)(tong)作渗(shen)透(tou)测试，并咨询制造厂。

紧缩空(kong)气(qi)(qi)耗(hao)量(liang)(liang)重要取决于喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)压(ya)力(li)(li)、喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)周期、喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)时(shi)(shi)辰(chen)、脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)方法和口径以及滤袋数(shu)等要素。为QMF—100型脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)在过滤风速必定(ding)而喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)压(ya)力(li)(li)不一(yi)起， 喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)时(shi)(shi)辰(chen)与耗(hao)气(qi)(qi)量(liang)(liang)的(de)(de)关系。除尘(chen)器的(de)(de)总耗(hao)气(qi)(qi)量(liang)(liang)Q可按(an)下式核算： 　　Q＝a•n•q/T式中(zhong)：Q—每(mei)(mei)除尘(chen)器耗(hao)气(qi)(qi)量(liang)(liang)，m3/min；a—附(fu)加系数(shu)（包含管(guan)道漏气(qi)(qi)）取1.2；n—脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)数(shu)目，个(ge)(ge)；q—每(mei)(mei)个(ge)(ge)脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)一(yi)次(ci)耗(hao)气(qi)(qi)量(liang)(liang)m3；一(yi)般喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)时(shi)(shi)辰(chen)0.15s；T—脉(mai)(mai)(mai)冲(chong)周期，min。如关于QMF—100型脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)，当喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)压(ya)力(li)(li)为0.5MPa—0.7MPa，喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)时(shi)(shi)辰(chen)为0.1s—0.2s时(shi)(shi)，每(mei)(mei)个(ge)(ge)脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)一(yi)次(ci)的(de)(de)耗(hao)气(qi)(qi)量(liang)(liang)为0.01m3—0.034m3；当喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)压(ya)力(li)(li)为0.4MPa—0.57MPa，喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)时(shi)(shi)辰(chen)为0.2s—0.3s时(shi)(shi)，每(mei)(mei)个(ge)(ge)脉(mai)(mai)(mai)冲(chong)阀(fa)(fa)喷(pen)(pen)(pen)吹(chui)(chui)(chui)(chui)一(yi)次(ci)的(de)(de)耗(hao)气(qi)(qi)量(liang)(liang)为0.025m3—0.036m3。

常见的除尘器布袋破损失效主要有磨损、烧损和腐蚀。滤筒除尘器滤袋磨损是指除尘布袋运用过程中，因重复的过滤与反吹状态切换，布袋鼓胀与缩短， 布袋与除尘骨架或其它构件间发生相对运动，高速含尘气流的冲刷等构成局部磨损。 布袋除尘器烧损是由于所处理的烟气反常高温、滤筒除尘器或高(gao)温(wen)尘(chen)粒(li)，温(wen)度高(gao)于(yu)滤料(liao)的耐受温(wen)度， 使受高(gao)温(wen)部位的滤料(liao)构成危害致使破(po)损。
