脈沖(chong)布(bu)袋(dai)(dai)除塵(chen)器(qi)是在布(bu)袋(dai)(dai)除塵(chen)器(qi)的(de)基礎上，改(gai)(gai)進的(de)新型脈沖(chong)袋(dai)(dai)式除塵(chen)器(qi)。為了進一步完善脈沖(chong)袋(dai)(dai)式除塵(chen)器(qi)，改(gai)(gai)后的(de)脈沖(chong)袋(dai)(dai)式除塵(chen)器(qi)保留了凈(jing)化效率高(gao)、處體(ti)能(neng)力大、性能(neng)穩定、操(cao)作方(fang)便、濾袋(dai)(dai)、維修工(gong)作量小等(deng)優(you)點。

       脈沖(chong)布袋(dai)(dai)(dai)除塵(chen)器由灰(hui)(hui)斗(dou)、上(shang)箱(xiang)體(ti)、中(zhong)箱(xiang)體(ti)、下(xia)箱(xiang)體(ti)等(deng)部(bu)分(fen)組成，上(shang)、中(zhong)、下(xia)箱(xiang)體(ti)為分(fen)室(shi)結(jie)構。工作時，含塵(chen)氣體(ti)由進(jin)風(feng)(feng)(feng)道進(jin)入灰(hui)(hui)斗(dou)，粗塵(chen)粒(li)直接落(luo)入灰(hui)(hui)斗(dou)底部(bu)，細塵(chen)粒(li)隨氣流(liu)(liu)轉折(zhe)向(xiang)上(shang)進(jin)入中(zhong)、下(xia)箱(xiang)體(ti)，粉塵(chen)積附在(zai)(zai)濾袋(dai)(dai)(dai)外表(biao)面(mian)，過濾后(hou)(hou)的(de)氣體(ti)進(jin)入上(shang)箱(xiang)體(ti)至(zhi)凈氣集(ji)合管(guan)-排(pai)(pai)風(feng)(feng)(feng)道，經排(pai)(pai)風(feng)(feng)(feng)機排(pai)(pai)至(zhi)。 清(qing)灰(hui)(hui)過程是先切斷該室(shi)的(de)凈氣出口風(feng)(feng)(feng)道，使該室(shi)的(de)布袋(dai)(dai)(dai)處于無氣流(liu)(liu)通(tong)過的(de)狀態(分(fen)室(shi)停風(feng)(feng)(feng)清(qing)灰(hui)(hui))。然后(hou)(hou)開啟脈沖(chong)閥用壓縮空氣進(jin)行(xing)脈沖(chong)噴吹清(qing)灰(hui)(hui)，切斷閥關(guan)閉時間在(zai)(zai)噴吹后(hou)(hou)從濾袋(dai)(dai)(dai)上(shang)剝(bo)離的(de)粉塵(chen)沉降至(zhi)灰(hui)(hui)斗(dou)，粉塵(chen)在(zai)(zai)脫離濾袋(dai)(dai)(dai)表(biao)面(mian)后(hou)(hou)又隨氣流(liu)(liu)附集(ji)到相鄰濾袋(dai)(dai)(dai)表(biao)面(mian)的(de)現象，使濾袋(dai)(dai)(dai)清(qing)灰(hui)(hui)，并由可編程序控(kong)制儀對排(pai)(pai)氣閥、脈沖(chong)閥及卸灰(hui)(hui)閥等(deng)進(jin)行(xing)全自動(dong)控(kong)制。

       由于采用分室停風脈沖噴吹清灰，噴吹就可達到清灰的目的，所以清灰周期，脈沖式布袋除塵器價(jia)格了清灰(hui)能耗(hao)，壓氣(qi)耗(hao)量可(ke)(ke)大為。同時，濾(lv)袋(dai)(dai)與脈沖(chong)閥的疲勞程(cheng)度也(ye)相應(ying)減低，從而成(cheng)地濾(lv)袋(dai)(dai)與閥片的壽(shou)命(ming)。檢修(xiu)換袋(dai)(dai)可(ke)(ke)在不(bu)停系統(tong)風機(ji)，系統(tong)正(zheng)常運行條件下(xia)分室進行。濾(lv)袋(dai)(dai)袋(dai)(dai)口(kou)采用彈性(xing)漲圈，密(mi)封性(xing)能好，濾(lv)袋(dai)(dai)龍骨采用多角形(xing)，減少了袋(dai)(dai)與龍骨的磨擦，了袋(dai)(dai)的壽(shou)命(ming)，又(you)便于卸袋(dai)(dai)。

       脈沖布(bu)袋除(chu)塵器(qi)清(qing)灰控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)采用PLC微電(dian)腦程控(kong)(kong)(kong)(kong)儀(yi)，分定(ding)(ding)(ding)(ding)壓(自(zi)動(dong)(dong)(dong))、定(ding)(ding)(ding)(ding)時(自(zi)動(dong)(dong)(dong))，手動(dong)(dong)(dong)三種控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)方式。 定(ding)(ding)(ding)(ding)壓控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)：按設定(ding)(ding)(ding)(ding)壓差進行控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，除(chu)塵器(qi)壓差過設定(ding)(ding)(ding)(ding)值(zhi)，各室(shi)(shi)(shi)自(zi)動(dong)(dong)(dong)依(yi)次清(qing)灰一遍。 定(ding)(ding)(ding)(ding)時控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)：按設定(ding)(ding)(ding)(ding)時間，每(mei)隔一個清(qing)灰周(zhou)期，各室(shi)(shi)(shi)依(yi)次清(qing)灰一遍。 手動(dong)(dong)(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)：在現場(chang)操作柜上可(ke)手動(dong)(dong)(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)依(yi)次各室(shi)(shi)(shi)自(zi)動(dong)(dong)(dong)清(qing)灰一遍，也可(ke)對每(mei)個室(shi)(shi)(shi)單(dan)獨清(qing)灰。 由用戶選(xuan)定(ding)(ding)(ding)(ding)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)方式，用戶無(wu)要求時，則按定(ding)(ding)(ding)(ding)時控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)供貨(huo)。
