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)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕(bu)廢氣(qi)中(zhong)的粉(fen)塵(chen)(chen)(chen)，它的凈(jing)化工作上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系統來(lai)完成(cheng)的，當含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)刺叭時(shi)，含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到(dao)氣(qi)流(liu)分(fen)布板以及(ji)折流(liu)板的調整(zheng)后，使氣(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面(mian)擴(kuo)大(da)的作用(yong)(yong)下(xia)，氣(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低(di)，其(qi)中(zhong)有些(xie)較重的塵(chen)(chen)(chen)粒便失去速(su)度(du)而(er)沉(chen)降(jiang)下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的含塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高(gao)壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的氣(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大(da)量(liang)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的粉(fen)塵(chen)(chen)(chen)結合起(qi)來(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的作用(yong)(yong)下(xia)趨(qu)向(xiang)本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用(yong)(yong)負高(gao)壓制(zhi))和陰(yin)極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)(zai)相應的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備(bei)陰(yin)陽極(ji)振(zhen)打系統的振(zhen)打，使沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的粉(fen)塵(chen)(chen)(chen)振(zhen)落(luo)，進(jin)人(ren)集灰斗 通過排灰裝置(zhi)放出(chu)，回收有物料，被)凈(jing)化的氣(qi)體(ti)(ti)(ti)排入大(da)氣(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工(gong)作原(yuan)理(li)是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與(yu)氣(qi)(qi)流(liu)分離。負極由不(bu)(bu)同斷面形狀的(de)(de)金屬(shu)導線(xian)制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)(bu)同幾何形狀的(de)(de)金屬(shu)板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質(zhi)、設備構造和(he)煙(yan)氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產(chan)生(sheng)局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)基本原理是利用電(dian)(dian)力捕集(ji)煙氣中的(de)(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互有關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕集(ji)。
