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)(dian)除塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化工作上要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀(dian)兩個系統來(lai)完成的(de)(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)體進(jin)人(ren)氣(qi)刺叭時，含(han)(han)塵(chen)(chen)氣(qi)體受到氣(qi)流(liu)分布板(ban)以(yi)及(ji)折流(liu)板(ban)的(de)(de)(de)調整(zheng)后，使氣(qi)流(liu)能較(jiao)均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)作用下，氣(qi)流(liu)速度(du)迅速降低，其中(zhong)有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失(shi)去速度(du)而(er)沉降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)(han)塵(chen)(chen)氣(qi)體由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)體中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下趨(qu)向本(ben)設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)采用負(fu)高壓(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉積(ji)在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)(tong)過(guo)設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)振打(da)，使沉積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集灰斗 通(tong)(tong)過(guo)排(pai)灰裝置放出，回收有物料，被)凈(jing)化的(de)(de)(de)氣(qi)體排(pai)入(ru)大(da)氣(qi)。

工作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)工(gong)作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)作用(yong)下(xia)與(yu)氣流分(fen)離。負極(ji)由(you)不(bu)(bu)同(tong)斷面形狀的(de)(de)金(jin)屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同(tong)幾何(he)形狀的(de)(de)金(jin)屬板制成(cheng)，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)性質、設備構(gou)造(zao)和(he)煙氣流速等三個因素的(de)(de)影響。粉(fen)(fen)塵(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)效率(lv)(lv)有直(zhi)接的(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難以保(bao)持在(zai)(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返(fan)氣流。比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到(dao)達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)(bu)易(yi)放出，在(zai)(zai)塵(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除塵(chen)效率(lv)(lv)下(xia)降(jiang)。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)基(ji)本原理是利用(yong)電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)粉塵(chen)(chen)，主要包括以下四個(ge)相互(hu)有關(guan)的(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)電(dian)(dian)離(li)。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)(de)捕集。
