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(chu)塵器是以(yi)靜電(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)中的(de)粉塵，它的(de)凈化工(gong)作(zuo)上要(yao)是依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)(chen)淀兩個系(xi)統來完(wan)成的(de)，當含塵氣(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵氣(qi)(qi)體(ti)受(shou)到氣(qi)(qi)流(liu)分(fen)布板以(yi)及(ji)折(zhe)流(liu)板的(de)調整后(hou)，使氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴大的(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速度(du)迅速降低，其中有(you)些(xie)(xie)較重的(de)塵粒(li)便失去速度(du)而(er)沉(chen)(chen)降下(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)含塵氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這(zhe)些(xie)(xie)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)粉塵結合起來，使塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)作(zuo)用(yong)下(xia)趨向本(ben)設備陽(yang)極(ji)(正極(ji)、本(ben)設備采用(yong)負(fu)高(gao)壓制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積(ji)(ji)在(zai)(zai)相應(ying)的(de)電(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設備陰(yin)陽(yang)極(ji)振(zhen)打(da)系(xi)統的(de)振(zhen)打(da)，使沉(chen)(chen)積(ji)(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵振(zhen)落，進(jin)(jin)人(ren)(ren)集(ji)灰(hui)斗 通(tong)過排(pai)(pai)灰(hui)裝置放(fang)(fang)出，回(hui)收(shou)有(you)物料，被)凈化的(de)氣(qi)(qi)體(ti)排(pai)(pai)入(ru)大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作(zuo)原理是利用高壓(ya)電(dian)(dian)場使煙(yan)氣(qi)發生(sheng)(sheng)電(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下與氣(qi)流(liu)分(fen)離(li)。負極(ji)由不同(tong)斷(duan)面形狀的(de)(de)(de)金(jin)屬(shu)(shu)導(dao)(dao)線制成，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形狀的(de)(de)(de)金(jin)屬(shu)(shu)板制成，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性(xing)能(neng)受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備(bei)構造和煙(yan)氣(qi)流(liu)速等三個(ge)因(yin)素的(de)(de)(de)影(ying)(ying)響。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻是評(ping)價導(dao)(dao)電(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)影(ying)(ying)響。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)阻過(guo)高，到(dao)達(da)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)壓(ya)梯度會產生(sheng)(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)現象。這(zhe)些情(qing)況(kuang)都(dou)會造成除塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)除塵(chen)器(qi)的基本原(yuan)理是利用電(dian)(dian)力捕集煙(yan)氣中的粉(fen)塵(chen)，主要包括以(yi)下四個相互有關的物(wu)理過程: (1) 氣體的電(dian)(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉(fen)塵(chen)的捕集。
