XWD型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)(jing)電(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以(yi)靜(jing)(jing)電(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收捕廢(fei)氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個(ge)系統(tong)來(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分(fen)布板以(yi)及折流板的(de)(de)(de)調(diao)整后，使(shi)(shi)氣(qi)(qi)流能(neng)較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面擴大(da)的(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流速(su)(su)度迅速(su)(su)降低(di)，其中(zhong)有(you)些(xie)較重的(de)(de)(de)塵(chen)(chen)粒(li)便失去(qu)速(su)(su)度而沉降下來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通(tong)人(ren)(ren)高壓直流電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存在(zai)(zai)(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)離子(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作(zuo)用(yong)下趨向本(ben)設備(bei)陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出(chu)(chu)電(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)過(guo)設備(bei)陰陽極(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)沉積在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放(fang)出(chu)(chu)，回收有(you)物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作原理是利用高(gao)壓(ya)電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與氣(qi)流分離。負極(ji)(ji)由不(bu)同(tong)斷面形(xing)狀的(de)(de)(de)金屬導(dao)線制成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾何形(xing)狀的(de)(de)(de)金屬板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構造(zao)和(he)煙氣(qi)流速等(deng)三個因(yin)素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是評價(jia)導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它(ta)對(dui)除塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重返(fan)氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)(dian)壓(ya)梯度會(hui)產生局(ju)部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造(zao)成除塵(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)器的(de)基(ji)本(ben)原(yuan)理是利(li)用電力捕集煙氣中的(de)粉塵(chen)，主(zhu)要包括以下四個(ge)相互有關的(de)物(wu)理過程: (1) 氣體(ti)的(de)電離。(2) 粉塵(chen)的(de)荷電。(3) 荷電粉塵(chen)向電極移(yi)動。(4) 荷電粉塵(chen)的(de)捕集。
