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(wo)式靜(jing)(jing)電(dian)(dian)(dian)除塵(chen)器(qi)是(shi)以(yi)靜(jing)(jing)電(dian)(dian)(dian)凈(jing)(jing)化法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)，它(ta)的(de)(de)(de)(de)凈(jing)(jing)化工作(zuo)上要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統來(lai)完成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流分布板以(yi)及折流板的(de)(de)(de)(de)調整后，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)橫斷面擴大(da)的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流速度迅速降(jiang)低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)粒便失(shi)去(qu)速度而沉降(jiang)下來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高壓直(zhi)流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)附(fu)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)(de)氣(qi)(qi)體(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下趨向本設備(bei)陽(yang)(yang)極(ji)(正極(ji)、本設備(bei)采用(yong)負高壓制)和(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分別(bie)沉積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通過設備(bei)陰陽(yang)(yang)極(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使(shi)(shi)沉積在(zai)陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)(fen)塵(chen)振(zhen)落，進(jin)人(ren)(ren)集灰(hui)斗 通過排(pai)灰(hui)裝(zhuang)置放出(chu)，回收有物料(liao)，被(bei))凈(jing)(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作原(yuan)理是利(li)用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)(qi)流分離。負(fu)極(ji)由不(bu)同(tong)斷面(mian)形狀的(de)(de)金(jin)屬導(dao)線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形狀的(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)(qi)流速等(deng)三個因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況(kuang)都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)基本原理(li)是利(li)用電(dian)(dian)力捕集(ji)煙氣(qi)中的(de)粉塵(chen)(chen)，主要包括以下(xia)四(si)個相互有關的(de)物理(li)過程(cheng): (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)捕集(ji)。
