礦山濾筒除塵器設備具有(you)體積小，，投資省，易維護等(deng)(deng)優點，但因其設備(bei)容量小，難(nan)組合(he)成大(da)風(feng)量設備(bei)，過濾(lv)風(feng)速偏低，應用范(fan)圍窄，僅(jin)在糧食(shi)、焊(han)接等(deng)(deng)行業應用，所(suo)以來未能(neng)大(da)量推廣。近年(nian)來，隨著、新材(cai)料不(bu)斷地(di)發展，使得濾(lv)筒除塵器廣泛地(di)應用于水泥、鋼鐵、電力(li)、食(shi)品、冶金(jin)、化工(gong)等(deng)(deng)工(gong)業領域。

含塵氣(qi)體進(jin)入除塵器(qi)灰斗后(hou)，由于氣(qi)流斷面突然擴(kuo)大及氣(qi)流分布板作用(yong)，氣(qi)流中一部分粗大顆粒(li)在動和慣(guan)性力作用(yong)下沉降在灰斗；粒(li)度細(xi)、密(mi)度小的塵粒(li)進(jin)入濾(lv)塵室(shi)(shi)后(hou)，通過(guo)布朗擴(kuo)散和篩(shai)濾(lv)等組合效應(ying)，使粉塵沉積在濾(lv)料表(biao)面上，凈化(hua)后(hou)的氣(qi)體進(jin)入凈氣(qi)室(shi)(shi)由排氣(qi)管經(jing)風機排出。

礦山濾筒除塵器設備濾筒式(shi)除塵(chen)(chen)器的(de)(de)阻力隨濾料表面(mian)粉(fen)塵(chen)(chen)層(ceng)厚度的(de)(de)增加而增大。阻力達到(dao)某(mou)一規定值時(shi)(shi)進行清(qing)(qing)(qing)灰。此時(shi)(shi)PLC程(cheng)序控制脈(mo)(mo)沖(chong)閥(fa)的(de)(de)啟閉(bi)，首(shou)先一分室(shi)提(ti)升(sheng)閥(fa)關閉(bi)，將過(guo)濾氣(qi)流截斷(duan)，然后電磁脈(mo)(mo)沖(chong)閥(fa)開(kai)(kai)啟，壓縮(suo)空氣(qi)以(yi)及短的(de)(de)時(shi)(shi)間在上(shang)箱體內迅速膨脹，涌(yong)入(ru)濾筒，使濾筒膨脹變形產生振動(dong)，并在逆(ni)向氣(qi)流沖(chong)刷(shua)的(de)(de)作用下，附著在濾袋外表面(mian)上(shang)的(de)(de)粉(fen)塵(chen)(chen)被剝離落入(ru)灰斗(dou)中。清(qing)(qing)(qing)灰完畢(bi)后，電磁脈(mo)(mo)沖(chong)閥(fa)關閉(bi)，提(ti)升(sheng)閥(fa)打(da)開(kai)(kai)，該室(shi)又恢復過(guo)濾狀態(tai)。清(qing)(qing)(qing)灰各室(shi)依次進行，從第(di)一室(shi)清(qing)(qing)(qing)灰開(kai)(kai)始(shi)(shi)至下一次清(qing)(qing)(qing)灰開(kai)(kai)始(shi)(shi)為一個清(qing)(qing)(qing)灰周期。脫落的(de)(de)粉(fen)塵(chen)(chen)掉入(ru)灰斗(dou)內通過(guo)缷(xie)灰閥(fa)排出。

濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)以濾(lv)(lv)(lv)筒(tong)(tong)(tong)作為(wei)過濾(lv)(lv)(lv)元件并采(cai)用脈沖反吹(chui)的除塵(chen)(chen)(chen)器(qi)。濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)按安裝方(fang)式分，可(ke)以分為(wei)斜(xie)插(cha)式，側裝式，吊裝式，上裝式等方(fang)式。濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)按濾(lv)(lv)(lv)筒(tong)(tong)(tong)材料(liao)分，可(ke)以分為(wei)長(chang)纖(xian)維聚酯濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)，復合纖(xian)維濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)，防靜電濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)，阻燃濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)，覆膜(mo)濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)，納米濾(lv)(lv)(lv)筒(tong)(tong)(tong)除塵(chen)(chen)(chen)器(qi)等。

濾筒脈沖除(chu)塵器具有體(ti)積(ji)小(xiao)，，投(tou)資省，易維護等優點，但因其設(she)備容量(liang)小(xiao)，難(nan)組合(he)成大(da)風量(liang)設(she)備，過濾風速(su)偏(pian)低，應(ying)用范圍窄，僅在糧食(shi)、焊接(jie)等行業應(ying)用，所以來未能大(da)量(liang)推廣。近(jin)年來，隨著、新材料不斷地發展(zhan)，使得濾筒除(chu)塵器廣泛地應(ying)用于(yu)水泥、鋼鐵、電力、食(shi)品、冶金、化工等工業。
