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。

臥式靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈化(hua)工作(zuo)上要(yao)是依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)極和(he)沉淀兩個系統來完成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板以(yi)及折流(liu)(liu)板的(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低(di)，其(qi)中有些較重的(de)(de)塵(chen)(chen)粒(li)便失去速(su)度而沉降下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)極附(fu)近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)體(ti)(ti)中存在大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)結合(he)起來，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作(zuo)用下(xia)趨(qu)向本設(she)備(bei)陽極(正極、本設(she)備(bei)采用負高壓制)和(he)陰(yin)極(負極) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過設(she)備(bei)陰(yin)陽極振打系統的(de)(de)振打，使(shi)沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)(ren)集灰斗 通(tong)過排灰裝(zhuang)置(zhi)放(fang)出(chu)，回收有物料，被)凈化(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)。

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原理是(shi)利(li)用高壓電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分離。負極(ji)(ji)由不(bu)同斷面(mian)形狀的(de)(de)金屬導線(xian)制(zhi)成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)(de)金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣(qi)(qi)流(liu)速等三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)(de)指標(biao)，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其(qi)重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵器的基(ji)本原理(li)(li)是利用(yong)電(dian)力捕(bu)(bu)集煙氣(qi)中的粉塵，主要(yao)包括以下四個(ge)相互有關(guan)的物理(li)(li)過程: (1) 氣(qi)體的電(dian)離。(2) 粉塵的荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動。(4) 荷電(dian)粉塵的捕(bu)(bu)集。
