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(yuan)理

靜電(dian)除塵(chen)(chen)器的(de)(de)工(gong)作原理是利用(yong)(yong)高壓電(dian)場使(shi)煙氣(qi)(qi)發生電(dian)離，氣(qi)(qi)流中的(de)(de)粉(fen)(fen)塵(chen)(chen)荷電(dian)在(zai)電(dian)場作用(yong)(yong)下(xia)與氣(qi)(qi)流分離。負極由(you)(you)不(bu)同斷面形(xing)狀的(de)(de)金屬導線制(zhi)成(cheng)，叫放(fang)電(dian)電(dian)極。正極由(you)(you)不(bu)同幾何形(xing)狀的(de)(de)金屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)電(dian)極。靜電(dian)除塵(chen)(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)(chen)性質(zhi)、設備(bei)構(gou)造和煙氣(qi)(qi)流速(su)等三個因素的(de)(de)影響。粉(fen)(fen)塵(chen)(chen)的(de)(de)比(bi)(bi)電(dian)阻(zu)是評價(jia)導電(dian)性的(de)(de)指標，它對除塵(chen)(chen)效率有直接的(de)(de)影響。比(bi)(bi)電(dian)阻(zu)過低(di)，塵(chen)(chen)粒難以(yi)保(bao)持在(zai)集(ji)塵(chen)(chen)電(dian)極上，致使(shi)其重(zhong)返氣(qi)(qi)流。比(bi)(bi)電(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)電(dian)極的(de)(de)塵(chen)(chen)粒電(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)壓梯度會(hui)(hui)產生局(ju)部擊穿和放(fang)電(dian)現象。這些情況都會(hui)(hui)造成(cheng)除塵(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)除塵器的(de)基(ji)本原(yuan)理是利用電(dian)(dian)(dian)力捕(bu)集(ji)煙(yan)氣(qi)中的(de)粉(fen)塵，主要(yao)包括以下四個(ge)相(xiang)互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵的(de)捕(bu)集(ji)。
