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。

臥式靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈化法來(lai)收捕(bu)廢氣(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和沉(chen)淀(dian)兩個系(xi)統(tong)來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)進人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)受到氣(qi)流分布板以及折流板的(de)(de)調整后(hou)(hou)，使(shi)(shi)(shi)氣(qi)流能較均勻地進人電(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)作用(yong)下，氣(qi)流速度迅速降低(di)，其中(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)(chen)粒便失去速度而(er)沉(chen)降下來(lai)。進人電(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)(tong)人高壓直流電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使(shi)(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)(hou)的(de)(de)氣(qi)體(ti)(ti)中(zhong)存(cun)在大量的(de)(de)電(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)子和離(li)子與(yu)進人電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合(he)起(qi)來(lai)，使(shi)(shi)(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)場力的(de)(de)作用(yong)下趨向本設(she)備陽(yang)(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備采用(yong)負高壓制(zhi))和陰(yin)(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子分別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)(tong)過(guo)設(she)備陰(yin)(yin)陽(yang)(yang)極(ji)(ji)(ji)(ji)振打系(xi)統(tong)的(de)(de)振打，使(shi)(shi)(shi)沉(chen)積在陰(yin)(yin)陽(yang)(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振落，進人集灰(hui)斗 通(tong)(tong)過(guo)排灰(hui)裝置放出，回收有物料，被)凈化的(de)(de)氣(qi)體(ti)(ti)排入大氣(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)工作原理是(shi)(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離(li)(li)。負極(ji)(ji)由(you)不(bu)(bu)同斷面形狀(zhuang)的(de)(de)金(jin)屬(shu)導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)(bu)同幾何形狀(zhuang)的(de)(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)性能受粉(fen)塵(chen)性質、設(she)備構造和煙氣(qi)流(liu)速等三個因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)(shi)評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標(biao)，它對除(chu)塵(chen)效率(lv)有直接的(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)粒難以保持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使(shi)其(qi)重返氣(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易(yi)放(fang)出，在(zai)塵(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會造成(cheng)除(chu)塵(chen)效率(lv)下降(jiang)。

電(dian)(dian)除塵器的(de)(de)基本原(yuan)理(li)是利(li)用電(dian)(dian)力捕集煙氣中(zhong)的(de)(de)粉(fen)(fen)(fen)塵，主要包括以下四(si)個相互有關的(de)(de)物理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)(fen)塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉(fen)(fen)(fen)塵的(de)(de)捕集。
