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)除塵器(qi)是(shi)以靜電(dian)(dian)凈(jing)化法來收捕廢(fei)氣(qi)中(zhong)(zhong)的(de)(de)(de)粉(fen)塵，它的(de)(de)(de)凈(jing)化工(gong)作(zuo)上要是(shi)依(yi)靠電(dian)(dian)暈(yun)極和(he)沉(chen)淀兩個系(xi)統來完成的(de)(de)(de)，當含塵氣(qi)體(ti)(ti)進(jin)人氣(qi)刺叭時，含塵氣(qi)體(ti)(ti)受到氣(qi)流分布板(ban)以及(ji)折流板(ban)的(de)(de)(de)調(diao)整后，使(shi)(shi)氣(qi)流能(neng)較(jiao)均勻地進(jin)人電(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)流速度迅(xun)速降(jiang)(jiang)低(di)，其中(zhong)(zhong)有(you)些(xie)較(jiao)重的(de)(de)(de)塵粒(li)便失(shi)去速度而沉(chen)降(jiang)(jiang)下(xia)來。進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)含塵氣(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極通(tong)人高壓直流電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極附近產生(sheng)電(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這(zhe)些(xie)電(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進(jin)人電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵結合起(qi)來，使(shi)(shi)塵粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵粒(li)在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用(yong)下(xia)趨(qu)向本(ben)設(she)(she)備(bei)陽極(正極、本(ben)設(she)(she)備(bei)采用(yong)負(fu)高壓制)和(he)陰(yin)極(負(fu)極) ， 釋放(fang)出(chu)電(dian)(dian)子(zi)(zi)分別沉(chen)積(ji)在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)極上，通(tong)過(guo)設(she)(she)備(bei)陰(yin)陽極振打系(xi)統的(de)(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)極上的(de)(de)(de)粉(fen)塵振落(luo)，進(jin)人集灰(hui)斗 通(tong)過(guo)排(pai)灰(hui)裝置(zhi)放(fang)出(chu)，回收有(you)物料(liao)，被)凈(jing)化的(de)(de)(de)氣(qi)體(ti)(ti)排(pai)入大氣(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流(liu)分離(li)。負極由不同斷面(mian)形狀的(de)金(jin)屬導(dao)線制成(cheng)，叫(jiao)(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同幾何形狀的(de)金(jin)屬板制成(cheng)，叫(jiao)(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備(bei)構(gou)造和煙氣(qi)流(liu)速等三個因素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)有直(zhi)接的(de)影響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)下降。

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)基(ji)本原理是利用電(dian)(dian)力捕集(ji)(ji)煙氣中(zhong)的(de)粉(fen)塵(chen)(chen)，主要包(bao)括以下四個相互有關的(de)物理過(guo)程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集(ji)(ji)。
