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)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)凈(jing)化法(fa)來收捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化工作上要是(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)(chen)淀兩個系(xi)統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分(fen)布板(ban)以及(ji)折流板(ban)的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)。在橫(heng)斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流速(su)(su)度(du)迅速(su)(su)降(jiang)低，其中有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便失去(qu)速(su)(su)度(du)而沉(chen)(chen)降(jiang)下(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由(you)于(yu)電(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流電(dian)(dian)，則在電(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)暈(yun)現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在大(da)量的(de)(de)(de)電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些(xie)電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在電(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用(yong)下(xia)趨(qu)向本設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用(yong)負高壓(ya)制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積在相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)上，通(tong)過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使(shi)沉(chen)(chen)積在陰陽(yang)電(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)(ren)集灰斗 通(tong)過(guo)排灰裝置放(fang)出，回(hui)收有物(wu)料，被(bei))凈(jing)化的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)(de)(de)(de)工作(zuo)原(yuan)理是(shi)利用(yong)高(gao)(gao)壓(ya)電(dian)(dian)(dian)場使(shi)煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用(yong)下與(yu)氣(qi)流分離。負極(ji)(ji)由不(bu)同斷(duan)面(mian)形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾(ji)何(he)形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設備構造和煙(yan)氣(qi)流速等三個因素的(de)(de)(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標，它對除(chu)(chu)塵(chen)效率有直接的(de)(de)(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)粒難(nan)以保持在(zai)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過高(gao)(gao)，到達集塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)壓(ya)梯(ti)度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象。這(zhe)些(xie)情(qing)況都會造成(cheng)除(chu)(chu)塵(chen)效率下降。

電(dian)除塵(chen)器(qi)的(de)基本原(yuan)理是利用電(dian)力捕集煙氣(qi)中的(de)粉塵(chen)，主要包(bao)括(kuo)以下四個相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離(li)。(2) 粉塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)的(de)捕集。
