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(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以靜(jing)(jing)電(dian)(dian)(dian)(dian)凈化法(fa)來(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作上(shang)(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)淀兩(liang)個系統來(lai)完(wan)成的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分(fen)(fen)布板以及(ji)折(zhe)流(liu)(liu)板的(de)(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)(liu)能較(jiao)均勻地(di)進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴大(da)的(de)(de)(de)(de)(de)(de)作用下，氣(qi)(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其(qi)中有些較(jiao)重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便失去速度而(er)沉(chen)降(jiang)下來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)(de)作用下趨向本設(she)備陽極(ji)(正極(ji)、本設(she)備采用負高壓制)和陰極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)分(fen)(fen)別沉(chen)積在相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)過(guo)設(she)備陰陽極(ji)振(zhen)打系統的(de)(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)積在陰陽電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)(ren)集灰斗 通(tong)過(guo)排灰裝置放(fang)出(chu)，回收(shou)有物料，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)。

工作(zuo)原理

靜電(dian)除(chu)塵(chen)(chen)器(qi)的(de)工(gong)作原理(li)是利用(yong)高(gao)(gao)壓電(dian)場(chang)使煙氣(qi)發生電(dian)離，氣(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)荷電(dian)在(zai)(zai)電(dian)場(chang)作用(yong)下與氣(qi)流(liu)分離。負極(ji)(ji)由(you)不(bu)同(tong)斷(duan)面形(xing)狀(zhuang)的(de)金屬導(dao)線制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)極(ji)(ji)。靜電(dian)除(chu)塵(chen)(chen)器(qi)的(de)性(xing)(xing)能受(shou)粉(fen)塵(chen)(chen)性(xing)(xing)質(zhi)、設備構造和(he)煙氣(qi)流(liu)速等(deng)三個(ge)因素的(de)影響(xiang)(xiang)。粉(fen)塵(chen)(chen)的(de)比(bi)(bi)電(dian)阻是評價導(dao)電(dian)性(xing)(xing)的(de)指標，它對除(chu)塵(chen)(chen)效(xiao)率有直接的(de)影響(xiang)(xiang)。比(bi)(bi)電(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)(zai)集(ji)塵(chen)(chen)電(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)流(liu)。比(bi)(bi)電(dian)阻過高(gao)(gao)，到(dao)達(da)集(ji)塵(chen)(chen)電(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)荷不(bu)易放(fang)出(chu)，在(zai)(zai)塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)壓梯(ti)度會產生局部擊(ji)穿和(he)放(fang)電(dian)現象。這些情(qing)況都會造成(cheng)除(chu)塵(chen)(chen)效(xiao)率下降。

電除(chu)塵器的(de)基本原理是(shi)利(li)用電力(li)捕集煙氣(qi)中的(de)粉(fen)塵，主要包括以下四個(ge)相互有(you)關的(de)物(wu)理過程: (1) 氣(qi)體的(de)電離。(2) 粉(fen)塵的(de)荷電。(3) 荷電粉(fen)塵向電極移動。(4) 荷電粉(fen)塵的(de)捕集。
