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。

臥式靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個系統來(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板(ban)以(yi)及折流板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)(qi)流能較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大的(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)(qi)(qi)流速度迅速降低，其中有些(xie)(xie)較重的(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去速度而沉(chen)降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使氣(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(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)(zuo)用(yong)下趨(qu)向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用(yong)負(fu)高壓制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使沉(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗(dou) 通過排灰裝置放出(chu)，回收有物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工作(zuo)原理是(shi)利用高壓電(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下(xia)(xia)與(yu)氣(qi)(qi)流分離。負極由不(bu)同(tong)斷面(mian)形狀的(de)金屬導線(xian)制成，叫放(fang)電(dian)(dian)電(dian)(dian)極。正極由不(bu)同(tong)幾何形狀的(de)金屬板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能(neng)受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性質(zhi)、設備構(gou)造和煙氣(qi)(qi)流速等(deng)三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)性的(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極上，致(zhi)使其重返氣(qi)(qi)流。比電(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿和放(fang)電(dian)(dian)現(xian)象。這些情(qing)況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率下(xia)(xia)降。

電(dian)除(chu)塵器的(de)基(ji)本原理(li)是利用電(dian)力捕集煙氣中的(de)粉(fen)塵，主要包(bao)括(kuo)以下四個相互有關的(de)物理(li)過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵的(de)捕集。
