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。

臥式靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化法來收捕(bu)廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)凈(jing)化工作上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩個系(xi)統(tong)來完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)調整后，使氣(qi)(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面擴(kuo)大的(de)(de)作用(yong)下，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低，其中有(you)些較重的(de)(de)塵(chen)(chen)(chen)粒便失(shi)去速(su)度而(er)沉降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)(ti)中存在大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向本(ben)設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)采用(yong)負(fu)高壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備(bei)陰陽(yang)極(ji)(ji)振打系(xi)統(tong)的(de)(de)振打，使沉積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)(jin)人(ren)(ren)集灰斗(dou) 通(tong)過排灰裝置(zhi)放出，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理(li)是(shi)利用高(gao)壓(ya)(ya)電(dian)場使煙氣發生電(dian)離，氣流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)在(zai)電(dian)場作(zuo)用下與氣流(liu)分(fen)離。負極由不(bu)(bu)同斷(duan)面形狀的(de)(de)(de)金屬(shu)(shu)導(dao)線制成(cheng)，叫放(fang)(fang)電(dian)電(dian)極。正(zheng)極由不(bu)(bu)同幾何(he)形狀的(de)(de)(de)金屬(shu)(shu)板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)極。靜電(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和(he)煙氣流(liu)速等三(san)個(ge)因素的(de)(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)阻是(shi)評價導(dao)電(dian)性的(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響(xiang)。比電(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)極上，致使其重返氣流(liu)。比電(dian)阻過高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷(he)不(bu)(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)壓(ya)(ya)梯度(du)會產生局部擊穿(chuan)和(he)放(fang)(fang)電(dian)現(xian)象。這些(xie)情況都(dou)會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電除塵器的基本原理是利用(yong)電力捕(bu)(bu)集煙氣中的粉塵，主要包(bao)括以下四個相互有關的物理過(guo)程: (1) 氣體的電離。(2) 粉塵的荷(he)電。(3) 荷(he)電粉塵向(xiang)電極(ji)移動。(4) 荷(he)電粉塵的捕(bu)(bu)集。
