XWD型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)除(chu)塵(chen)(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)凈化(hua)(hua)法來收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)(qi)中的(de)粉塵(chen)(chen)(chen)，它的(de)凈化(hua)(hua)工作上要是(shi)依靠電(dian)(dian)(dian)暈極和沉(chen)(chen)淀兩個系(xi)統(tong)來完成的(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)調(diao)整后，使(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻(yun)地(di)進人(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)(jiang)低，其中有(you)(you)些較重的(de)塵(chen)(chen)(chen)粒(li)便失去速(su)度(du)而沉(chen)(chen)降(jiang)(jiang)下(xia)來。進人(ren)電(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈極通人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極附近(jin)產生電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)電(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)子和離子與進人(ren)電(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)(chen)結(jie)合(he)起來，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作用(yong)下(xia)趨向(xiang)本設備陽(yang)(yang)極(正(zheng)極、本設備采(cai)用(yong)負高壓(ya)制)和陰(yin)(yin)極(負極) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)(chen)積在(zai)相(xiang)應的(de)電(dian)(dian)(dian)極上，通過設備陰(yin)(yin)陽(yang)(yang)極振打(da)(da)系(xi)統(tong)的(de)振打(da)(da)，使(shi)(shi)沉(chen)(chen)積在(zai)陰(yin)(yin)陽(yang)(yang)電(dian)(dian)(dian)極上的(de)粉塵(chen)(chen)(chen)振落，進人(ren)集(ji)灰斗(dou) 通過排灰裝置(zhi)放(fang)出，回收(shou)有(you)(you)物料(liao)，被)凈化(hua)(hua)的(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)工作原理(li)是(shi)利用(yong)高壓(ya)電(dian)(dian)(dian)場使(shi)煙氣發生(sheng)電(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)(xia)與氣流分離。負極(ji)(ji)由不(bu)(bu)(bu)同(tong)斷面形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)導(dao)線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)(bu)同(tong)幾何形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)性能(neng)受粉(fen)塵(chen)(chen)性質、設備構造和煙氣流速等三個因素(su)的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率(lv)有直(zhi)接的(de)(de)影響。比電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難(nan)以保(bao)持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使(shi)其重返(fan)氣流。比電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)(bu)(bu)易(yi)放(fang)(fang)出，在塵(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)效率(lv)下(xia)(xia)降。

電(dian)(dian)除塵(chen)器的(de)基本原理(li)是利用(yong)電(dian)(dian)力捕(bu)集煙氣(qi)中(zhong)的(de)粉塵(chen)，主要包(bao)括以下四個相互(hu)有關的(de)物理(li)過程: (1) 氣(qi)體(ti)的(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)的(de)捕(bu)集。
