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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉淀兩(liang)個系(xi)(xi)統來(lai)完成的(de)(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)刺叭時，含塵(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)分(fen)(fen)布板(ban)以(yi)及(ji)折(zhe)流(liu)板(ban)的(de)(de)(de)(de)(de)(de)調整后，使氣(qi)流(liu)能較均勻地(di)進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作用下，氣(qi)流(liu)速(su)度(du)迅速(su)降低，其中有些(xie)較重的(de)(de)(de)(de)(de)(de)塵(chen)粒(li)便失去速(su)度(du)而沉降下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)結合起來(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)(de)(de)作用下趨向本設(she)備陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備采用負高壓(ya)制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)(fen)別沉積(ji)在(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備陰(yin)陽極(ji)(ji)振(zhen)打系(xi)(xi)統的(de)(de)(de)(de)(de)(de)振(zhen)打，使沉積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通過排灰裝置放(fang)出，回收有物料(liao)，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)排入(ru)大(da)氣(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)工作原理是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與(yu)氣(qi)(qi)(qi)流(liu)分(fen)離(li)。負極(ji)(ji)由(you)不同斷(duan)面形狀的(de)金屬(shu)導(dao)線制成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)金屬(shu)板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)性能受(shou)粉(fen)塵(chen)(chen)性質、設(she)備構造和煙氣(qi)(qi)(qi)流(liu)速(su)等(deng)三個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它(ta)對(dui)除(chu)(chu)塵(chen)(chen)效率(lv)有直(zhi)接的(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣(qi)(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到(dao)達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層(ceng)之(zhi)間形成電(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成除(chu)(chu)塵(chen)(chen)效率(lv)下降。

電除塵(chen)器(qi)的(de)基本原理(li)(li)是利用電力捕(bu)集煙氣中的(de)粉塵(chen)，主要包括以(yi)下(xia)四(si)個相(xiang)互有(you)關(guan)的(de)物理(li)(li)過程: (1) 氣體的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極(ji)移動。(4) 荷(he)電粉塵(chen)的(de)捕(bu)集。
