脈沖濾筒除塵器

脈沖濾筒(tong)(tong)除塵(chen)(chen)(chen)器設(she)有進(jin)(jin)風(feng)口(kou)、濾筒(tong)(tong)、出(chu)(chu)風(feng)口(kou)、氣(qi)(qi)(qi)(qi)(qi)包、脈沖控(kong)(kong)制(zhi)(zhi)儀、噴(pen)(pen)吹(chui)(chui)閥、噴(pen)(pen)吹(chui)(chui)管(guan)等，濾筒(tong)(tong)是由(you)聚脂纖維(wei)折疊(die)、卷制(zhi)(zhi)而成，其下端封閉，上(shang)端正對噴(pen)(pen)吹(chui)(chui)管(guan)下口(kou)。含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體由(you)進(jin)(jin)風(feng)口(kou)進(jin)(jin)入(ru)除塵(chen)(chen)(chen)器后，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速度(du)減慢，粗顆粒脫離氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)沉降(jiang)到集塵(chen)(chen)(chen)室(shi)內(nei)，細微粉(fen)塵(chen)(chen)(chen)隨氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)穿(chuan)過(guo)(guo)濾筒(tong)(tong)時被阻于(yu)濾筒(tong)(tong)外(wai)(wai)表(biao)(biao)面，潔凈氣(qi)(qi)(qi)(qi)(qi)體由(you)出(chu)(chu)風(feng)口(kou)排出(chu)(chu);當(dang)濾筒(tong)(tong)表(biao)(biao)面灰(hui)層較厚時，脈沖控(kong)(kong)制(zhi)(zhi)儀發出(chu)(chu)指(zhi)令開啟噴(pen)(pen)吹(chui)(chui)閥，氣(qi)(qi)(qi)(qi)(qi)包內(nei)的(de)壓縮空氣(qi)(qi)(qi)(qi)(qi)經噴(pen)(pen)吹(chui)(chui)管(guan)高速噴(pen)(pen)出(chu)(chu)，同時誘導數(shu)倍(bei)于(yu)噴(pen)(pen)射氣(qi)(qi)(qi)(qi)(qi)量的(de)周(zhou)圍(wei)空氣(qi)(qi)(qi)(qi)(qi)進(jin)(jin)入(ru)濾筒(tong)(tong)，并由(you)內(nei)向外(wai)(wai)射出(chu)(chu)，將濾筒(tong)(tong)外(wai)(wai)表(biao)(biao)面的(de)粉(fen)塵(chen)(chen)(chen)吹(chui)(chui)下落入(ru)集塵(chen)(chen)(chen)室(shi)內(nei)，然后由(you)放(fang)灰(hui)斗排出(chu)(chu)。除塵(chen)(chen)(chen)器清(qing)灰(hui)采用脈沖噴(pen)(pen)吹(chui)(chui)方(fang)式，既做到了(le)   清(qing)灰(hui)，又不傷害(hai)濾筒(tong)(tong)，使(shi)濾筒(tong)(tong)使(shi)用壽命(ming)得(de)以。清(qing)灰(hui)過(guo)(guo)程(cheng)由(you)脈沖控(kong)(kong)制(zhi)(zhi)儀自動(dong)控(kong)(kong)制(zhi)(zhi)，可采用壓力差控(kong)(kong)制(zhi)(zhi)或時間控(kong)(kong)制(zhi)(zhi)。

脈沖(chong)濾筒(tong)(tong)除塵(chen)(chen)器為(wei)負壓運行(xing)，含塵(chen)(chen)氣流(liu)(liu)從位于除塵(chen)(chen)器上部(bu)的(de)(de)進(jin)(jin)風口(kou)下(xia)行(xing)進(jin)(jin)入(ru)箱體(ti)，箱體(ti)內的(de)(de)導流(liu)(liu)板(ban)迫使(shi)氣流(liu)(liu)向下(xia)穿過(guo)濾筒(tong)(tong)，由(you)于氣流(liu)(liu)斷面突然擴(kuo)大，氣流(liu)(liu)中一(yi)部(bu)分(fen)顆粒(li)粗(cu)大的(de)(de)塵(chen)(chen)粒(li)在(zai)(zai)重力和慣性力作用下(xia)沉降(jiang)下(xia)來，粒(li)度細、密度小的(de)(de)塵(chen)(chen)粒(li)進(jin)(jin)入(ru)過(guo)濾室后(hou)，通過(guo)布朗擴(kuo)散和篩濾等綜(zong)合效(xiao)應使(shi)粉塵(chen)(chen)沉積在(zai)(zai)濾料表面，凈(jing)化后(hou)的(de)(de)空(kong)氣透過(guo)濾料進(jin)(jin)入(ru)清潔室從出(chu)風口(kou)排出(chu)．當粉塵(chen)(chen)在(zai)(zai)濾料表面上越(yue)積越(yue)多，阻(zu)力達(da)到設定值時，脈沖(chong)閥打(da)開，壓縮空(kong)氣直接噴入(ru)濾筒(tong)(tong)，對濾筒(tong)(tong)進(jin)(jin)行(xing)順序(xu)脈沖(chong)清灰(hui)，抖(dou)落(luo)積塵(chen)(chen)，使(shi)其恢復低阻(zu)運行(xing)，掉入(ru)灰(hui)斗(dou)內收集的(de)(de)粉塵(chen)(chen)通過(guo)卸灰(hui)閥連續排出(chu)．維修時，只需要人工(gong)將檢修蓋(gai)上的(de)(de)手輪旋下(xia)即可(ke)輕松(song)取(qu)出(chu)濾筒(tong)(tong)。
