脈沖(chong)收塵器工作原理：
此(ci)類脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)工作時(shi)，含(han)塵(chen)(chen)(chen)(chen)氣(qi)體由脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)的(de)進(jin)氣(qi)口(kou)進(jin)入(ru)箱(xiang)體，通(tong)過(guo)脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)濾袋(dai)得以凈化，凈氣(qi)孔經文氏管進(jin)入(ru)脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)上箱(xiang)體，并(bing)從脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)的(de)排(pai)(pai)氣(qi)口(kou)排(pai)(pai)出(chu)，脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)濾袋(dai)外表(biao)面粉塵(chen)(chen)(chen)(chen)不斷增加，使脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)的(de)阻力增大，為使此(ci)脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)式(shi)收(shou)(shou)塵(chen)(chen)(chen)(chen)設備(bei)阻力維持在(zai) 范圍，要 脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)濾袋(dai)表(biao)面的(de)灰塵(chen)(chen)(chen)(chen)。脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)式(shi)收(shou)(shou)塵(chen)(chen)(chen)(chen)設備(bei)在(zai)清(qing)灰時(shi)由控制(zhi)(zhi)儀定期順(shun)序觸發各控制(zhi)(zhi)閥，開啟嵌入(ru)式(shi)脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)閥，使脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)布袋(dai)除塵(chen)(chen)(chen)(chen)器(qi)氣(qi)包內壓(ya)縮空氣(qi)由脈(mo)(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)(chong)(chong)式(shi)收(shou)(shou)塵(chen)(chen)(chen)(chen)設備(bei)噴吹(chui)管上的(de)噴嘴(zui)噴出(chu)（一(yi)次風）， 通(tong)過(guo)文氏管誘導數倍于一(yi)次風的(de)周圍空氣(qi)（二次風）進(jin)入(ru)濾袋(dai)，在(zai)瞬間產生振動(dong)波與(yu)逆向(xiang)氣(qi)流(liu)，抖下(xia)粉塵(chen)(chen)(chen)(chen)，落入(ru)下(xia)箱(xiang)體，經排(pai)(pai)風閥排(pai)(pai)出(chu)機體。
YMD型低(di)壓噴(pen)(pen)(pen)吹(chui)(chui)脈(mo)沖(chong)袋(dai)式除塵(chen)(chen)器(qi)的 要結構與MC型除塵(chen)(chen)器(qi)一樣。其 要特征在于采納單膜片直通(tong)式脈(mo)沖(chong)閥，增大噴(pen)(pen)(pen)吹(chui)(chui)管直徑，以噴(pen)(pen)(pen)嘴替(ti)代傳統的噴(pen)(pen)(pen)孔(kong)，然后下降噴(pen)(pen)(pen)吹(chui)(chui)壓力。商品(pin)功能安穩，除塵(chen)(chen)作用(yong)好，讓您環境 潔凈.
YMD型(xing)低壓噴(pen)吹(chui)脈沖(chong)袋式除塵器濾(lv)袋與花孔板之間(jian)用軟(ruan)質墊料保(bao)持密封，并(bing)用楔(xie)銷壓緊。頂蓋也用楔(xie)銷壓緊，能夠便利地敞開。噴(pen)吹(chui)管(guan)和穩(wen)壓氣(qi)包之間(jian)有(you)軟(ruan)聯接，換袋時可(ke)將其豎起，將濾(lv)袋同引射器和袋籠向上(shang)抽出，在布袋除塵器外面拆換。
采用進(jin)步風(feng)方法，含塵氣體由中箱(xiang)體上部進(jin)入，靠擋板引向濾(lv)袋(dai)頂(ding)部，再流向除塵濾(lv)袋(dai)。
這種除塵器(qi)的 要(yao)特點：
（1）噴吹(chui)(chui)壓力低，為0.2～0.3MPa，為高壓噴吹(chui)(chui)的1/2～1/3。
（2）含塵氣(qi)流在箱(xiang)體內的流動(dong)方向(xiang)與粉塵沉降方向(xiang)共同(tong)，減少了“二次揚塵”景象，因此(ci)壓力丟失低。
（3）拆換(huan)除塵(chen)布袋(dai)較(jiao)為便利。
