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。

工作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器的工作原(yuan)理是(shi)(shi)利用高(gao)壓(ya)電(dian)(dian)場(chang)(chang)使煙氣發生電(dian)(dian)離，氣流中的粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)(chang)作用下(xia)與氣流分離。負(fu)極(ji)由(you)不(bu)(bu)同斷面形狀的金屬(shu)導線制成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同幾何形狀的金屬(shu)板制成，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器的性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣流速等三個因素的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)阻(zu)(zu)(zu)是(shi)(shi)評價導電(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)(chen)效率有(you)直接的影響。比電(dian)(dian)阻(zu)(zu)(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重(zhong)返氣流。比電(dian)(dian)阻(zu)(zu)(zu)過高(gao)，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)壓(ya)梯度會產生局部擊穿和放電(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)除塵(chen)器的(de)(de)基(ji)本原理是利(li)用電(dian)(dian)(dian)力(li)捕(bu)集煙氣中(zhong)的(de)(de)粉(fen)塵(chen)，主要包括以下四(si)個相(xiang)互有關的(de)(de)物(wu)理過(guo)程: (1) 氣體的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)捕(bu)集。
