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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來收(shou)捕(bu)廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀(dian)兩(liang)個系統來完(wan)成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人氣(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)受(shou)到氣(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)流(liu)能較均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)流(liu)速(su)(su)度迅速(su)(su)降(jiang)(jiang)低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失(shi)去速(su)(su)度而(er)沉降(jiang)(jiang)下(xia)(xia)來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來，使(shi)(shi)(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)趨向本(ben)設備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設備(bei)采(cai)用(yong)負(fu)高壓(ya)(ya)制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設備(bei)陰(yin)陽(yang)(yang)極(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使(shi)(shi)(shi)沉積在(zai)(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人集灰斗(dou) 通過(guo)排灰裝置(zhi)放出(chu)，回收(shou)有物料，被)凈(jing)(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)工作原理是利用高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與氣(qi)流分(fen)離。負極(ji)(ji)(ji)(ji)由不(bu)同斷面形狀(zhuang)的(de)金屬導線制(zhi)成，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不(bu)同幾何(he)形狀(zhuang)的(de)金屬板(ban)制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)流速(su)等三(san)個因素的(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)影(ying)響(xiang)。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓(ya)梯度會(hui)產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)造(zao)成除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)基本原理(li)是(shi)利用(yong)電(dian)(dian)(dian)力捕(bu)集(ji)煙氣中的(de)(de)粉(fen)塵(chen)(chen)，主要包(bao)括(kuo)以下四個相(xiang)互有關(guan)的(de)(de)物(wu)理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集(ji)。
