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)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)凈化法來收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)凈化工作(zuo)上要是(shi)依靠電(dian)暈(yun)(yun)極(ji)(ji)和(he)(he)沉淀兩個系統來完成(cheng)的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流分布板以及(ji)折流板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能(neng)較均(jun)勻地進人(ren)電(dian)場。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流速度迅(xun)速降(jiang)低，其中有些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度而(er)沉降(jiang)下來。進人(ren)電(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)高(gao)壓直流電(dian)，則在(zai)電(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)離，電(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)中存(cun)在(zai)大(da)量的(de)(de)電(dian)子和(he)(he)離子，這(zhe)些電(dian)子和(he)(he)離子與進人(ren)電(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)，帶電(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)場力的(de)(de)作(zuo)用下趨向本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采(cai)用負(fu)高(gao)壓制(zhi))和(he)(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出(chu)(chu)電(dian)子分別沉積在(zai)相應的(de)(de)電(dian)極(ji)(ji)上，通(tong)過(guo)設(she)備陰陽極(ji)(ji)振(zhen)打(da)系統的(de)(de)振(zhen)打(da)，使(shi)沉積在(zai)陰陽電(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放出(chu)(chu)，回收有物料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是利用高壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)分離。負極(ji)由不(bu)同斷面形狀的(de)金屬(shu)導(dao)線制成(cheng)(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀的(de)金屬(shu)板制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備構造和煙氣(qi)流(liu)速等三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生局(ju)部擊穿(chuan)和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)基本(ben)原(yuan)理是利用電(dian)(dian)(dian)(dian)力捕集煙(yan)氣中(zhong)的(de)粉(fen)塵(chen)(chen)，主要包括以下四個相互有關的(de)物(wu)理過程: (1) 氣體的(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷(he)電(dian)(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)向(xiang)電(dian)(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
