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)除(chu)塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)(hua)(hua)法來(lai)收捕廢氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)(hua)(hua)工作上要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩個系統來(lai)完(wan)成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板(ban)以(yi)及折流板(ban)的(de)(de)調(diao)整(zheng)后，使(shi)氣(qi)(qi)流能(neng)較均勻(yun)地進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)。在橫(heng)斷面(mian)擴大的(de)(de)作用下，氣(qi)(qi)流速(su)度(du)迅速(su)降低，其(qi)中有些較重的(de)(de)塵(chen)(chen)粒便失去速(su)度(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高壓(ya)直流電(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)離(li)(li)(li)后的(de)(de)氣(qi)(qi)體(ti)中存在大量(liang)的(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)(li)子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備(bei)采(cai)用負高壓(ya)制)和(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)(tong)過設備(bei)陰陽(yang)極(ji)(ji)(ji)(ji)振打系統的(de)(de)振打，使(shi)沉(chen)積在陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集(ji)灰(hui)斗 通(tong)(tong)過排(pai)灰(hui)裝(zhuang)置放(fang)出，回收有物料(liao)，被(bei))凈(jing)化(hua)(hua)(hua)的(de)(de)氣(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)。

工(gong)作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流分離(li)。負(fu)極(ji)由不(bu)同斷面(mian)形(xing)狀的(de)(de)金屬導線制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形(xing)狀的(de)(de)金屬板制成，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性能(neng)受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣流速(su)等(deng)三個因素(su)的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)有直(zhi)接(jie)的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以(yi)保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣流。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情(qing)況都會(hui)造成除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)除(chu)塵(chen)器的(de)(de)(de)基(ji)本原理(li)是(shi)利用(yong)電(dian)力(li)捕集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)，主要包(bao)括以(yi)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(fen)塵(chen)的(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵(chen)的(de)(de)(de)捕集。
