在(zai)工(gong)業窯爐上(shang)，脈(mo)沖布袋除塵器(qi)在(zai)熱電、鋼鐵(tie)、水泥和垃(la)圾焚燒等行(xing)業的應用(yong)已(yi)經(jing)較為普遍，相較于(yu)電除塵器(qi)都取(qu)得了顯(xian)著的經(jing)濟效益(yi)和社會效益(yi)。
脈(mo)沖(chong)(chong)(chong)(chong)布袋(dai)除塵(chen)器是通(tong)(tong)過(guo)脈(mo)沖(chong)(chong)(chong)(chong)清(qing)灰方式清(qing)灰來進行清(qing)灰，它由脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)、噴(pen)(pen)(pen)吹管(guan)、貯(zhu)氣(qi)(qi)包和脈(mo)沖(chong)(chong)(chong)(chong)控(kong)制(zhi)(zhi)(zhi)儀(yi)等幾(ji)部分組成，分室(shi)除塵(chen)器另外加(jia)有(you)氣(qi)(qi)缸。脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)一(yi)端連接(jie)壓(ya)(ya)(ya)縮空(kong)氣(qi)(qi)包，另一(yi)端連接(jie)噴(pen)(pen)(pen)吹管(guan)，脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)背壓(ya)(ya)(ya)室(shi)接(jie)控(kong)制(zhi)(zhi)(zhi)閥(fa)(fa)(fa)，脈(mo)沖(chong)(chong)(chong)(chong)控(kong)制(zhi)(zhi)(zhi)儀(yi)控(kong)制(zhi)(zhi)(zhi)著控(kong)制(zhi)(zhi)(zhi)閥(fa)(fa)(fa)及脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)的(de)(de)開(kai)啟。當(dang)控(kong)制(zhi)(zhi)(zhi)儀(yi)無(wu)信號(hao)輸出(chu)時(shi)，控(kong)制(zhi)(zhi)(zhi)閥(fa)(fa)(fa)的(de)(de)排氣(qi)(qi)口被關(guan)(guan)閉，脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)噴(pen)(pen)(pen)口處關(guan)(guan)閉狀態，當(dang)控(kong)制(zhi)(zhi)(zhi)儀(yi)發出(chu)信號(hao)時(shi)，控(kong)制(zhi)(zhi)(zhi)閥(fa)(fa)(fa)排氣(qi)(qi)口被打(da)開(kai)，脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)背壓(ya)(ya)(ya)室(shi)外的(de)(de)氣(qi)(qi)體泄掉壓(ya)(ya)(ya)力降(jiang)低，膜片(pian)兩(liang)面產生壓(ya)(ya)(ya)差，膜片(pian)因(yin)壓(ya)(ya)(ya)差作(zuo)用而產生移位，脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)噴(pen)(pen)(pen)吹打(da)開(kai)，此時(shi)壓(ya)(ya)(ya)縮空(kong)氣(qi)(qi)從氣(qi)(qi)包通(tong)(tong)過(guo)脈(mo)沖(chong)(chong)(chong)(chong)閥(fa)(fa)(fa)經噴(pen)(pen)(pen)吹管(guan)小孔(kong)噴(pen)(pen)(pen)出(chu)（從噴(pen)(pen)(pen)吹管(guan)噴(pen)(pen)(pen)出(chu)的(de)(de)氣(qi)(qi)體為一(yi)次風）。當(dang)高速氣(qi)(qi)流通(tong)(tong)過(guo)文氏管(guan)誘導(dao)(dao)器誘導(dao)(dao)了數倍于一(yi)次風的(de)(de)周(zhou)圍(wei)空(kong)氣(qi)(qi)進入濾袋(dai)，造(zao)成濾袋(dai)內瞬間時(shi)正壓(ya)(ya)(ya)，實現(xian)脈(mo)沖(chong)(chong)(chong)(chong)清(qing)灰。
脈沖(chong)布袋除(chu)塵(chen)器(qi)在后期(qi)使用維護過程：
一(yi)、配備(bei)磨內噴水的磨機(ji)，要霧化良好。停磨前提前一(yi)刻(ke)鐘(zhong)停水。避免水分蒸(zheng)發滯(zhi)后對濾袋帶來不(bu)良影響。
二、濾袋清掃(sao)用風(feng)風(feng)壓維(wei)(wei)持在 0.5MPa 以上，要求油(you)水分離，氣包要及(ji)時放水。經常(chang)(chang)檢查(cha)袋除塵(chen)器內(nei)部風(feng)路(lu)開閉(bi)、控(kong)制清掃(sao)用風(feng)等(deng)。檢查(cha)濾袋堵塞程度，發現輕度堵塞，要及(ji)時抽出干(gan)燥、拍打清堵。通風(feng)能(neng)力維(wei)(wei)持正常(chang)(chang)，避(bi)免堵塞仍繼續運轉(zhuan)形成惡性循環。
三、對廢(fei)氣(qi)處理系(xi)統漏風進行經常性(xing)檢查，實施堵(du)漏，對出磨廢(fei)氣(qi)系(xi)統進行 的(de)外保溫。
四、低(di)溫季(ji)節冷磨(mo)(mo)開機，盡量避免溫升(sheng)期物(wu)料過大(da)水(shui)分入磨(mo)(mo)；要(yao)注意控制加(jia)料速度；圈(quan)流磨(mo)(mo)可加(jia)大(da)回粉量提升(sheng)磨(mo)(mo)內風(feng)溫。停磨(mo)(mo)前盡可能適當(dang)延(yan)長(chang)止料時間(jian)，及早對高水(shui)分含量的混(hun)合材止料，停磨(mo)(mo)后適當(dang)延(yan)長(chang)磨(mo)(mo)內排(pai)風(feng)時間(jian)，同時做好(hao)磨(mo)(mo)體轉置。
五、倉(cang)研磨(mo)體填充(chong)量要適宜(yi)，避免影(ying)響(xiang)中空軸部位的通風(feng)(feng)面(mian)積。篦(bi)縫堵塞要及時清理，禁(jin)止混合材中混有鐵渣之類物質(zhi)入磨(mo)，以(yi)避免堵塞篦(bi)縫。要維(wei)持磨(mo)內通風(feng)(feng)能力(li)穩(wen)定在(zai)良好水平；—旦有變(bian)化，仍可(ke)由排(pai)風(feng)(feng)機抽力(li)來調整(zheng)維(wei)持磨(mo)內 佳通風(feng)(feng)量。
