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(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是利用(yong)(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)(yong)下(xia)與氣(qi)流(liu)分離(li)。負極(ji)(ji)由(you)不(bu)(bu)同斷面形狀的(de)(de)(de)(de)金(jin)屬(shu)導(dao)線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)(bu)同幾(ji)何形狀的(de)(de)(de)(de)金(jin)屬(shu)板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設(she)備構造和(he)煙氣(qi)流(liu)速等(deng)三個因素(su)的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情況都會(hui)(hui)造成除塵(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)除塵(chen)器的(de)基本原(yuan)理是利用電(dian)力捕(bu)集煙氣(qi)中的(de)粉(fen)塵(chen)，主(zhu)要(yao)包(bao)括以下四個(ge)相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕(bu)集。
