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。

工作(zuo)原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作用(yong)下(xia)(xia)與氣(qi)流分離。負極(ji)(ji)由不(bu)(bu)同(tong)斷面(mian)形(xing)狀的(de)(de)金屬導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)(bu)同(tong)幾何(he)形(xing)狀的(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)性(xing)(xing)能受粉塵(chen)(chen)(chen)性(xing)(xing)質、設備構造和(he)煙氣(qi)流速(su)等(deng)三個因素的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它對除塵(chen)(chen)(chen)效率(lv)有直接(jie)的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保(bao)持(chi)在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)(he)不(bu)(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)(chen)效率(lv)下(xia)(xia)降。

電除塵(chen)(chen)器的(de)(de)基(ji)本原(yuan)理是利用電力捕集(ji)煙(yan)氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)，主要(yao)包括以下四(si)個相(xiang)互(hu)有關的(de)(de)物理過(guo)程: (1) 氣(qi)(qi)體(ti)(ti)的(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電。(3) 荷(he)電粉塵(chen)(chen)向電極移動。(4) 荷(he)電粉塵(chen)(chen)的(de)(de)捕集(ji)。
