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)式靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化工作上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈極和(he)(he)沉(chen)淀兩個系(xi)統來完(wan)成的(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流(liu)能較均勻地(di)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便(bian)失去速(su)度而沉(chen)降下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈極通(tong)人(ren)(ren)高(gao)(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合(he)起(qi)來，使(shi)(shi)塵(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下(xia)趨向本設(she)備(bei)陽(yang)極(正極、本設(she)備(bei)采用負(fu)高(gao)(gao)壓(ya)制)和(he)(he)陰極(負(fu)極) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極上，通(tong)過設(she)備(bei)陰陽(yang)極振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰陽(yang)電(dian)(dian)(dian)(dian)極上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放出(chu)，回(hui)收(shou)有物(wu)料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作原理是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)(qi)流(liu)分離(li)。負極(ji)(ji)由不(bu)(bu)同斷(duan)面形狀的(de)(de)金屬導線制成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)(bu)同幾何(he)形狀的(de)(de)金屬板制成，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)(zao)和(he)煙氣(qi)(qi)流(liu)速等三個(ge)因素的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其(qi)重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放(fang)(fang)出(chu)，在塵(chen)(chen)(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生(sheng)局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)(zao)成除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除(chu)塵(chen)器(qi)的(de)(de)基本原理(li)(li)是(shi)利用電(dian)力捕集(ji)煙氣中(zhong)的(de)(de)粉(fen)(fen)(fen)塵(chen)，主要包括以下四個相互(hu)有關的(de)(de)物理(li)(li)過(guo)程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)(fen)(fen)塵(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)(fen)塵(chen)向(xiang)電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)捕集(ji)。
