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(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)凈(jing)化法來收(shou)捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作(zuo)上要是依靠電(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀(dian)兩個(ge)系統(tong)來完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體進人氣(qi)(qi)(qi)刺叭時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體受到(dao)氣(qi)(qi)(qi)流分(fen)布板以(yi)及(ji)折流板的(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)流能(neng)較均勻地進人電(dian)(dian)場。在(zai)(zai)(zai)橫斷面擴大的(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流速度迅速降(jiang)低，其中(zhong)有些(xie)(xie)較重的(de)(de)塵(chen)(chen)(chen)粒(li)(li)便(bian)失去速度而沉(chen)降(jiang)下(xia)來。進人電(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)暈(yun)極(ji)(ji)通人高(gao)壓直流電(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產(chan)生電(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)(qi)體中(zhong)存(cun)在(zai)(zai)(zai)大量的(de)(de)電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些(xie)(xie)電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進人電(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來，使(shi)塵(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在(zai)(zai)(zai)電(dian)(dian)場力的(de)(de)作(zuo)用下(xia)趨向本設備陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用負(fu)高(gao)壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放出(chu)電(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積(ji)在(zai)(zai)(zai)相(xiang)應的(de)(de)電(dian)(dian)極(ji)(ji)上，通過(guo)設備陰陽(yang)(yang)極(ji)(ji)振打(da)系統(tong)的(de)(de)振打(da)，使(shi)沉(chen)積(ji)在(zai)(zai)(zai)陰陽(yang)(yang)電(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振落，進人集灰斗(dou) 通過(guo)排灰裝置放出(chu)，回收(shou)有物(wu)料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原(yuan)理是(shi)利(li)用(yong)高(gao)壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣(qi)流分(fen)離。負(fu)極由(you)不(bu)同斷面(mian)形狀的(de)(de)金(jin)屬(shu)導線制成，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形狀的(de)(de)金(jin)屬(shu)板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構(gou)造(zao)和(he)煙氣(qi)流速等三(san)個因素(su)的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)(de)指(zhi)標，它(ta)對除(chu)塵(chen)(chen)(chen)效率有(you)直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返氣(qi)流。比電(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會產生局部擊穿(chuan)和(he)放(fang)(fang)電(dian)(dian)(dian)現象。這些(xie)情況都會造(zao)成除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)基本原理是利用電(dian)(dian)(dian)(dian)(dian)力捕(bu)集煙(yan)氣(qi)(qi)中(zhong)的(de)粉塵(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣(qi)(qi)體的(de)電(dian)(dian)(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)(dian)(dian)粉塵(chen)的(de)捕(bu)集。
