XDCD型低壓脈沖袋式除塵器是一種采用脈沖清灰方式的小型脈沖袋式除塵器,它具有結構緊湊,清灰方式簡單可靠,更換濾袋方便,收塵效率高等優點,廣泛應用于冶金、化工、建材等工礦企業。
工作原理
含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)由(you)進(jin)氣(qi)(qi)(qi)口進(jin)入(ru)(ru)箱體(ti)(ti)(ti)(ti)(ti),通(tong)(tong)過濾(lv)袋(dai)得以凈(jing)化,凈(jing)氣(qi)(qi)(qi)經文氏管(guan)進(jin)入(ru)(ru)上箱體(ti)(ti)(ti)(ti)(ti),從排(pai)氣(qi)(qi)(qi)口排(pai)出(chu),濾(lv)袋(dai)外(wai)表面(mian)粉塵(chen)(chen)(chen)不斷增加,使(shi)除塵(chen)(chen)(chen)器阻力增大,為(wei)是設備阻力維持在(zai)_范圍,要_濾(lv)袋(dai)表面(mian)的(de)(de)灰(hui)塵(chen)(chen)(chen),清(qing)灰(hui)時由(you)控(kong)制儀定期順序觸發各控(kong)制閥,開啟電磁脈沖(chong)(chong)閥,使(shi)氣(qi)(qi)(qi)包內壓(ya)縮空(kong)氣(qi)(qi)(qi)由(you)噴吹管(guan)上的(de)(de)噴追噴出(chu)(一(yi)次(ci)(ci)風(feng)),通(tong)(tong)過文氏管(guan)誘導數倍于一(yi)次(ci)(ci)風(feng)的(de)(de)周圍空(kong)氣(qi)(qi)(qi)(二次(ci)(ci)風(feng))進(jin)入(ru)(ru)濾(lv)袋(dai),在(zai)瞬間(jian)產(chan)生振動波與逆向氣(qi)(qi)(qi)流(liu),抖下(xia)粉塵(chen)(chen)(chen),落入(ru)(ru)下(xia)箱體(ti)(ti)(ti)(ti)(ti),經卸(xie)灰(hui)閥排(pai)出(chu)機(ji)體(ti)(ti)(ti)(ti)(ti)。在(zai)清(qing)灰(hui)過程(cheng)中(zhong),每次(ci)(ci)噴吹的(de)(de)時間(jian)稱脈沖(chong)(chong)寬度(du),一(yi)般僅(jin)0.1-0.2秒(miao),全(quan)部濾(lv)袋(dai)完成一(yi)個清(qing)灰(hui)循(xun)環的(de)(de)時間(jian)稱為(wei)脈沖(chong)(chong)周期。
