臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥(wo)式(shi)靜電(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)法來收捕廢氣中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系統來完(wan)成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣體(ti)(ti)進人(ren)(ren)(ren)(ren)氣刺叭時，含(han)塵(chen)(chen)氣體(ti)(ti)受到(dao)氣流分布板以(yi)及折(zhe)流板的(de)(de)(de)(de)調整后，使氣流能(neng)較(jiao)(jiao)均勻(yun)地(di)進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面(mian)擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣流速(su)度迅速(su)降(jiang)低，其(qi)中(zhong)有些較(jiao)(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度而(er)沉(chen)(chen)降(jiang)下(xia)來。進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)氣體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)(ren)高壓直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)(yun)現象，使氣體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣體(ti)(ti)中(zhong)存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離子(zi)與(yu)進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨向本(ben)(ben)設備(bei)陽極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)(ben)設備(bei)采用(yong)負高壓制)和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設備(bei)陰陽極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使沉(chen)(chen)積(ji)在(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)振落，進人(ren)(ren)(ren)(ren)集(ji)灰(hui)斗 通(tong)過排灰(hui)裝置放(fang)出(chu)，回(hui)收有物料，被)凈化(hua)的(de)(de)(de)(de)氣體(ti)(ti)排入大氣。

工作原(yuan)理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)工作原理是利用(yong)高(gao)壓電(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)下與氣(qi)流(liu)(liu)分離。負(fu)極(ji)(ji)由(you)不(bu)同斷面(mian)形狀的(de)金(jin)屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同幾何形狀的(de)金(jin)屬板制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)性質(zhi)、設備構造(zao)和(he)(he)煙氣(qi)流(liu)(liu)速等(deng)三個(ge)因素的(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)影(ying)響(xiang)。比(bi)(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重(zhong)返(fan)氣(qi)流(liu)(liu)。比(bi)(bi)電(dian)(dian)阻過高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之(zhi)間形成(cheng)(cheng)電(dian)(dian)壓梯(ti)度會(hui)產生(sheng)局部(bu)擊(ji)穿和(he)(he)放電(dian)(dian)現(xian)象。這些情況都會(hui)造(zao)成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵器(qi)的(de)(de)基本原理是利用電(dian)力捕集(ji)煙氣中(zhong)的(de)(de)粉(fen)塵，主要包括以下四(si)個相互有(you)關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)塵的(de)(de)捕集(ji)。
