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)(dian)除塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)，它的(de)(de)凈(jing)化(hua)工(gong)作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉(chen)淀(dian)兩(liang)個系(xi)統(tong)來完成(cheng)的(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)進人(ren)氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以(yi)及折流板的(de)(de)調(diao)整后，使(shi)氣(qi)(qi)流能較均勻(yun)地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴大的(de)(de)作(zuo)(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)流速(su)度迅速(su)降(jiang)(jiang)低，其中有(you)些(xie)較重的(de)(de)塵(chen)粒(li)便失去速(su)度而沉(chen)降(jiang)(jiang)下(xia)(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)氣(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人(ren)高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)體(ti)中存在(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)結合起來，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)(zuo)用(yong)下(xia)(xia)趨(qu)向本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采用(yong)負高壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過(guo)設(she)備陰(yin)陽極(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)振(zhen)打，使(shi)沉(chen)積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)振(zhen)落，進人(ren)集灰(hui)斗 通過(guo)排灰(hui)裝置放出，回收有(you)物(wu)料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工(gong)作(zuo)原理

靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是(shi)利(li)用高壓電(dian)(dian)場使煙氣(qi)(qi)(qi)發生電(dian)(dian)離(li)，氣(qi)(qi)(qi)流中的(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下與氣(qi)(qi)(qi)流分離(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀的(de)(de)金屬(shu)導(dao)(dao)線制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何(he)形(xing)狀的(de)(de)金屬(shu)板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能受(shou)粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造(zao)和煙氣(qi)(qi)(qi)流速等三個因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是(shi)評價導(dao)(dao)電(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)影響(xiang)。比電(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)粒(li)難以(yi)保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使其(qi)重返氣(qi)(qi)(qi)流。比電(dian)(dian)阻過高，到(dao)達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)壓梯度會產生局(ju)部擊穿和放電(dian)(dian)現(xian)象。這些情況都會造(zao)成除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的基本(ben)原理(li)是利用電(dian)力捕集煙氣中(zhong)的粉塵，主要包括以下(xia)四個相互有關的物(wu)理(li)過程(cheng): (1) 氣體(ti)的電(dian)離(li)。(2) 粉塵的荷電(dian)。(3) 荷電(dian)粉塵向(xiang)電(dian)極移(yi)動。(4) 荷電(dian)粉塵的捕集。
