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(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工(gong)作原(yuan)理是(shi)(shi)利(li)用高壓電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流(liu)中(zhong)的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場作用下(xia)與(yu)氣流(liu)分離。負極(ji)由不(bu)(bu)(bu)同(tong)斷面(mian)形狀的(de)(de)金屬(shu)導線制成，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)(bu)同(tong)幾何形狀的(de)(de)金屬(shu)板制成，叫集塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備(bei)構造和煙氣流(liu)速(su)等三個因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)是(shi)(shi)評(ping)價(jia)導電(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣流(liu)。比(bi)電(dian)(dian)阻(zu)過(guo)高，到(dao)達集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷(he)不(bu)(bu)(bu)易放出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)壓梯度(du)會(hui)(hui)產生局部擊(ji)穿和放電(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成除(chu)塵(chen)(chen)效率下(xia)降。

電除塵器的基本原(yuan)理(li)是(shi)利(li)用電力捕集煙氣(qi)中的粉(fen)塵，主(zhu)要包括以(yi)下四個相互有(you)關(guan)的物理(li)過程: (1) 氣(qi)體的電離。(2) 粉(fen)塵的荷(he)電。(3) 荷(he)電粉(fen)塵向電極移動。(4) 荷(he)電粉(fen)塵的捕集。
