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)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化法(fa)來(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)凈化工作上(shang)要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)布(bu)板(ban)以及折流(liu)板(ban)的(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能(neng)較均勻(yun)地(di)進人(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷(duan)面擴大(da)的(de)(de)作用下，氣(qi)(qi)流(liu)速度迅速降低，其中有些(xie)較重的(de)(de)塵(chen)(chen)粒(li)便失去速度而(er)沉(chen)降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)體由(you)于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)體中存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)作用下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設(she)備(bei)采用負高壓制)和(he)陰極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積(ji)在(zai)(zai)相(xiang)應(ying)的(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設(she)備(bei)陰陽(yang)極(ji)振打系(xi)統的(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)振落，進人(ren)(ren)集灰斗(dou) 通過(guo)排灰裝(zhuang)置放出，回(hui)收(shou)有物(wu)料，被)凈化的(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是(shi)利用高(gao)壓(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與氣(qi)(qi)流(liu)分離。負(fu)極由(you)(you)不(bu)同(tong)斷面形(xing)狀的(de)金屬導(dao)線(xian)制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)(you)不(bu)同(tong)幾何形(xing)狀的(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備構(gou)造和煙氣(qi)(qi)流(liu)速等三個(ge)因素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)性(xing)的(de)指(zhi)標(biao)，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返(fan)氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度會(hui)產(chan)生局部(bu)擊穿和放電(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會(hui)造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)除(chu)塵器的基本原理是利用(yong)電(dian)力捕集煙(yan)氣中的粉(fen)塵，主(zhu)要(yao)包括以下四個(ge)相互(hu)有(you)關的物理過程: (1) 氣體的電(dian)離。(2) 粉(fen)塵的荷(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)塵的捕集。
