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(jing)電(dian)(dian)(dian)(dian)除塵器是以靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收(shou)捕(bu)廢氣(qi)(qi)中(zhong)(zhong)的(de)粉(fen)塵，它的(de)凈化(hua)(hua)工(gong)作上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)和沉淀兩(liang)個系統來(lai)完成(cheng)的(de)，當(dang)含(han)塵氣(qi)(qi)體(ti)(ti)(ti)(ti)進人(ren)(ren)氣(qi)(qi)刺叭(ba)時，含(han)塵氣(qi)(qi)體(ti)(ti)(ti)(ti)受(shou)到氣(qi)(qi)流分布板以及(ji)折流板的(de)調(diao)整后，使氣(qi)(qi)流能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴大的(de)作用(yong)下，氣(qi)(qi)流速(su)度迅速(su)降(jiang)低，其中(zhong)(zhong)有些(xie)較重的(de)塵粒便失去速(su)度而沉降(jiang)下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)含(han)塵氣(qi)(qi)體(ti)(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)中(zhong)(zhong)存在(zai)大量的(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)粉(fen)塵結合起來(lai)，使塵粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)場力(li)的(de)作用(yong)下趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用(yong)負高(gao)壓制)和陰極(ji)(負極(ji)) ， 釋放(fang)出(chu)(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉積(ji)在(zai)相應(ying)的(de)電(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設備(bei)陰陽極(ji)振(zhen)打系統的(de)振(zhen)打，使沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)上的(de)粉(fen)塵振(zhen)落，進人(ren)(ren)集(ji)灰斗(dou) 通過(guo)排灰裝置放(fang)出(chu)(chu)，回收(shou)有物料，被(bei))凈化(hua)(hua)的(de)氣(qi)(qi)體(ti)(ti)(ti)(ti)排入大氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除塵(chen)器的(de)工作(zuo)原(yuan)理是利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)(qi)(qi)流中的(de)粉塵(chen)荷(he)(he)電(dian)(dian)(dian)在(zai)(zai)(zai)電(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)(qi)(qi)流分(fen)離。負極(ji)(ji)由(you)不(bu)同(tong)斷面形(xing)狀的(de)金屬導線制成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)狀的(de)金屬板制成，叫集塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)器的(de)性(xing)能受粉塵(chen)性(xing)質、設(she)備(bei)構造和煙氣(qi)(qi)(qi)流速等三個因素(su)的(de)影(ying)響。粉塵(chen)的(de)比電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)效率有直接的(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以保(bao)持(chi)在(zai)(zai)(zai)集塵(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)(qi)(qi)流。比電(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)粒(li)電(dian)(dian)(dian)荷(he)(he)不(bu)易放(fang)出，在(zai)(zai)(zai)塵(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)壓(ya)梯度會產生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)現(xian)象。這些(xie)情況都會造成除塵(chen)效率下降。

電(dian)除塵器的基本原理(li)是(shi)利用電(dian)力捕集煙(yan)氣(qi)中的粉塵，主要包括以下(xia)四個相互(hu)有關的物理(li)過程: (1) 氣(qi)體的電(dian)離。(2) 粉塵的荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移(yi)動(dong)。(4) 荷電(dian)粉塵的捕集。
