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(shi)靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈化(hua)法(fa)來收(shou)捕廢氣(qi)(qi)中的粉塵(chen)(chen)，它的凈化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀(dian)兩個系統來完成的，當含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分布板以(yi)及折(zhe)流(liu)板的調整后，使氣(qi)(qi)流(liu)能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大(da)(da)(da)的作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有(you)些(xie)較重(zhong)的塵(chen)(chen)粒(li)便失去速(su)度而沉降下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)大(da)(da)(da)量(liang)的電(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力的作(zuo)用(yong)下(xia)趨向本(ben)設(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)在(zai)(zai)相應的電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設(she)備(bei)陰陽極(ji)(ji)振(zhen)打系統的振(zhen)打，使沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上的粉塵(chen)(chen)振(zhen)落，進人(ren)(ren)集灰斗 通(tong)過排灰裝置放(fang)(fang)出，回(hui)收(shou)有(you)物料，被)凈化(hua)的氣(qi)(qi)體(ti)(ti)排入大(da)(da)(da)氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除塵器(qi)的(de)(de)(de)工作原理是利用高(gao)壓(ya)(ya)電(dian)(dian)(dian)場使煙(yan)氣發(fa)生(sheng)電(dian)(dian)(dian)離(li)，氣流中的(de)(de)(de)粉塵荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與氣流分離(li)。負極(ji)由不同斷面形(xing)狀的(de)(de)(de)金屬導(dao)(dao)線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾(ji)何形(xing)狀的(de)(de)(de)金屬板制成(cheng)(cheng)，叫(jiao)集塵電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵器(qi)的(de)(de)(de)性(xing)能受粉塵性(xing)質、設備構造和煙(yan)氣流速等(deng)三個因(yin)素的(de)(de)(de)影響。粉塵的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵粒(li)難(nan)以保持在(zai)集塵電(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流。比(bi)電(dian)(dian)(dian)阻過(guo)高(gao)，到達(da)集塵電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵粒(li)電(dian)(dian)(dian)荷(he)不易放出，在(zai)塵層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這(zhe)些情況(kuang)都(dou)會造成(cheng)(cheng)除塵效率下降。

電(dian)除塵器(qi)的(de)基本(ben)原理是利用電(dian)力捕集煙氣中的(de)粉(fen)塵，主要(yao)包(bao)括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向電(dian)極移動(dong)。(4) 荷(he)電(dian)粉(fen)塵的(de)捕集。
