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)除(chu)塵(chen)(chen)器是以(yi)靜電(dian)(dian)凈(jing)(jing)化法(fa)來收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)(de)凈(jing)(jing)化工作上(shang)要是依靠電(dian)(dian)暈極和沉(chen)(chen)淀(dian)兩個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板以(yi)及(ji)折流板的(de)(de)(de)(de)(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)流能較均勻地進(jin)人(ren)電(dian)(dian)場(chang)。在橫斷(duan)面擴(kuo)大的(de)(de)(de)(de)(de)(de)(de)作用下，氣(qi)(qi)流速度迅速降低，其(qi)中(zhong)有些(xie)較重的(de)(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒便失去(qu)速度而沉(chen)(chen)降下來。進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)暈極通(tong)(tong)(tong)人(ren)高壓(ya)直流電(dian)(dian)，則在電(dian)(dian)暈極附近產(chan)生電(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)體電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)體中(zhong)存在大量的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)(de)(de)(de)作用下趨(qu)向本設(she)(she)備(bei)陽(yang)極(正極、本設(she)(she)備(bei)采用負(fu)高壓(ya)制)和陰(yin)極(負(fu)極) ， 釋放(fang)出電(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積在相應的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)極上(shang)，通(tong)(tong)(tong)過(guo)設(she)(she)備(bei)陰(yin)陽(yang)極振(zhen)(zhen)打(da)(da)系(xi)統(tong)的(de)(de)(de)(de)(de)(de)(de)振(zhen)(zhen)打(da)(da)，使(shi)沉(chen)(chen)積在陰(yin)陽(yang)電(dian)(dian)極上(shang)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)集灰斗 通(tong)(tong)(tong)過(guo)排(pai)灰裝置放(fang)出，回收有物料(liao)，被)凈(jing)(jing)化的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)體排(pai)入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工作原(yuan)理是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)(yan)氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)作用下與(yu)氣(qi)(qi)流(liu)分離。負(fu)極(ji)(ji)(ji)由(you)不(bu)(bu)同(tong)斷面形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)導線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不(bu)(bu)同(tong)幾何形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)板(ban)制(zhi)成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和(he)煙(yan)(yan)氣(qi)(qi)流(liu)速等(deng)三個因素的(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難(nan)以保持在集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致使其重(zhong)返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生局(ju)部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)除塵器的(de)(de)(de)基本原(yuan)理(li)是(shi)利(li)用電(dian)力捕(bu)集(ji)煙氣(qi)中的(de)(de)(de)粉塵，主要包括(kuo)以下四個相互有關的(de)(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)(de)電(dian)離。(2) 粉塵的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極(ji)移動(dong)。(4) 荷電(dian)粉塵的(de)(de)(de)捕(bu)集(ji)。
