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)除塵(chen)器(qi)是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)化工作上(shang)(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個(ge)系(xi)(xi)統(tong)來(lai)完(wan)成的(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以(yi)及折流(liu)(liu)板的(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較(jiao)均(jun)勻地(di)進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大(da)的(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中有(you)些較(jiao)重的(de)(de)塵(chen)粒(li)便失去速度而沉(chen)降(jiang)下(xia)來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附(fu)近產(chan)生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)中存在大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子和(he)(he)離子，這些電(dian)(dian)(dian)(dian)子和(he)(he)離子與進人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合(he)起來(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下(xia)趨向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高壓制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通過設備陰陽極(ji)(ji)(ji)振(zhen)打系(xi)(xi)統(tong)的(de)(de)振(zhen)打，使(shi)沉(chen)積在陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進人(ren)(ren)集灰斗 通過排灰裝置(zhi)放出，回(hui)收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與(yu)氣(qi)(qi)流分離(li)。負極(ji)(ji)由不同(tong)(tong)斷面形(xing)狀的金(jin)屬(shu)導(dao)線制成，叫(jiao)(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)(tong)幾何形(xing)狀的金(jin)屬(shu)板制成，叫(jiao)(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣(qi)(qi)流速等三(san)個因(yin)素的影響(xiang)。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的指(zhi)標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)效率(lv)有直接的影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造成除(chu)塵(chen)(chen)(chen)效率(lv)下(xia)降(jiang)。

電(dian)除塵(chen)(chen)器的(de)(de)基(ji)本原(yuan)理是利(li)用電(dian)力(li)捕集(ji)煙氣中(zhong)的(de)(de)粉塵(chen)(chen)，主(zhu)要包括以下四個相互有(you)關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電(dian)離(li)。(2) 粉塵(chen)(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向(xiang)電(dian)極移動。(4) 荷電(dian)粉塵(chen)(chen)的(de)(de)捕集(ji)。
