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)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)凈化工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系統來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流分布板以及折流板的(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)(qi)流能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)場。在橫(heng)斷(duan)面擴大的(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流速度迅速降低，其中(zhong)有些(xie)較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去(qu)速度而沉降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下趨向本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉積在相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設備(bei)陰陽(yang)極(ji)(ji)振打系統的(de)(de)(de)(de)振打，使沉積在陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)人(ren)集灰斗 通(tong)過(guo)排灰裝置放出(chu)，回收有物(wu)料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)的(de)(de)工(gong)作原理是利用高壓(ya)電(dian)(dian)場使煙(yan)氣發生電(dian)(dian)離(li)，氣流中的(de)(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣流分離(li)。負極(ji)(ji)(ji)由不(bu)同(tong)斷(duan)面形(xing)狀(zhuang)的(de)(de)金屬導線(xian)制成(cheng)(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)金屬板制成(cheng)(cheng)，叫集(ji)塵(chen)電(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)的(de)(de)性能受粉塵(chen)性質、設(she)備(bei)構造(zao)和煙(yan)氣流速等三個(ge)因素的(de)(de)影響(xiang)。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)阻是評(ping)價(jia)導電(dian)(dian)性的(de)(de)指標，它對除(chu)(chu)(chu)塵(chen)效(xiao)率有直(zhi)接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)粒難以保持在集(ji)塵(chen)電(dian)(dian)極(ji)(ji)(ji)上(shang)，致使其重返氣流。比(bi)電(dian)(dian)阻過(guo)高，到(dao)達集(ji)塵(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)層之間(jian)形(xing)成(cheng)(cheng)電(dian)(dian)壓(ya)梯度(du)會(hui)產生局部擊穿和放(fang)電(dian)(dian)現象(xiang)。這(zhe)些情況都會(hui)造(zao)成(cheng)(cheng)除(chu)(chu)(chu)塵(chen)效(xiao)率下降。

電(dian)除塵(chen)(chen)器的(de)(de)基本原(yuan)理(li)(li)是(shi)利用電(dian)力捕集煙氣(qi)(qi)中的(de)(de)粉(fen)(fen)塵(chen)(chen)，主(zhu)要(yao)包括以下四(si)個相互有(you)關的(de)(de)物理(li)(li)過程: (1) 氣(qi)(qi)體(ti)的(de)(de)電(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕集。
