礦山濾筒除塵器設備具有體(ti)積小(xiao)，，投資省，易維護等(deng)優點(dian)，但因(yin)其設(she)備容量(liang)小(xiao)，難組合成大風量(liang)設(she)備，過濾風速(su)偏低(di)，應用(yong)范圍窄，僅在糧食、焊接等(deng)行業(ye)應用(yong)，所以(yi)來未能大量(liang)推廣。近年來，隨著、新(xin)材料不斷地(di)發(fa)展，使得濾筒除(chu)塵器廣泛地(di)應用(yong)于水泥、鋼(gang)鐵、電力(li)、食品、冶金、化工(gong)等(deng)工(gong)業(ye)領域。

含塵氣(qi)(qi)(qi)(qi)體進入除塵器灰斗后，由于氣(qi)(qi)(qi)(qi)流斷面(mian)突然擴大及氣(qi)(qi)(qi)(qi)流分布(bu)板作用(yong)，氣(qi)(qi)(qi)(qi)流中一部分粗(cu)大顆粒(li)在(zai)動和慣性(xing)力作用(yong)下沉降在(zai)灰斗；粒(li)度(du)細、密度(du)小的塵粒(li)進入濾塵室后，通過(guo)布(bu)朗擴散(san)和篩濾等組合效應(ying)，使粉(fen)塵沉積(ji)在(zai)濾料表(biao)面(mian)上，凈化后的氣(qi)(qi)(qi)(qi)體進入凈氣(qi)(qi)(qi)(qi)室由排氣(qi)(qi)(qi)(qi)管(guan)經風機(ji)排出。

礦山濾筒除塵器設備濾(lv)(lv)筒(tong)式除塵器的(de)(de)阻力隨濾(lv)(lv)料表面粉塵層厚度的(de)(de)增(zeng)加(jia)而增(zeng)大。阻力達到(dao)某(mou)一規定值時(shi)進(jin)行(xing)(xing)清灰。此時(shi)PLC程(cheng)序控制脈(mo)沖(chong)閥(fa)的(de)(de)啟(qi)閉(bi)，首先(xian)一分室提升(sheng)閥(fa)關(guan)閉(bi)，將過濾(lv)(lv)氣(qi)流截斷，然后電(dian)磁脈(mo)沖(chong)閥(fa)開啟(qi)，壓縮空氣(qi)以及短的(de)(de)時(shi)間在上箱體(ti)內(nei)迅速(su)膨脹(zhang)，涌入(ru)(ru)濾(lv)(lv)筒(tong)，使(shi)濾(lv)(lv)筒(tong)膨脹(zhang)變形(xing)產(chan)生振動，并(bing)在逆(ni)向氣(qi)流沖(chong)刷的(de)(de)作用(yong)下，附著在濾(lv)(lv)袋外表面上的(de)(de)粉塵被剝離落入(ru)(ru)灰斗(dou)中。清灰完(wan)畢后，電(dian)磁脈(mo)沖(chong)閥(fa)關(guan)閉(bi)，提升(sheng)閥(fa)打開，該室又恢(hui)復過濾(lv)(lv)狀(zhuang)態。清灰各室依次(ci)(ci)進(jin)行(xing)(xing)，從第(di)一室清灰開始至下一次(ci)(ci)清灰開始為一個清灰周期。脫(tuo)落的(de)(de)粉塵掉(diao)入(ru)(ru)灰斗(dou)內(nei)通過缷(xie)灰閥(fa)排出。

濾(lv)(lv)筒脈沖(chong)除(chu)塵器具有體積(ji)小(xiao)，，投(tou)資省，易維護等優點(dian)，但因其設備容量(liang)小(xiao)，難組合成大(da)風量(liang)設備，過濾(lv)(lv)風速偏低，應用(yong)范圍窄，僅(jin)在糧食、焊接等行業應用(yong)，所以來未能(neng)大(da)量(liang)推廣(guang)。近年來，隨著、新材料不斷地發展，使得濾(lv)(lv)筒除(chu)塵器廣(guang)泛地應用(yong)于水泥、鋼鐵、電力、食品、冶(ye)金、化工等工業。
