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)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈化(hua)工作上要(yao)是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀兩個(ge)系統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)體進(jin)人(ren)氣(qi)刺叭(ba)時(shi)，含(han)塵(chen)(chen)氣(qi)體受到氣(qi)流(liu)分布板(ban)以及(ji)折流(liu)板(ban)的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)能(neng)較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)場。在橫斷面擴大(da)的(de)(de)(de)(de)作用(yong)下，氣(qi)流(liu)速(su)度迅速(su)降(jiang)低，其中有些(xie)較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒便失去(qu)速(su)度而沉(chen)降(jiang)下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)體中存在大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)結(jie)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)場力的(de)(de)(de)(de)作用(yong)下趨向本(ben)設(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設(she)備(bei)采(cai)用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)分別沉(chen)積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備(bei)陰陽極(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)積在陰陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放(fang)出，回收有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)體排入大(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)工(gong)作(zuo)(zuo)原理是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)塵荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)(zuo)用下與氣(qi)流(liu)分離。負(fu)極由不(bu)同斷面形(xing)狀的(de)(de)金屬(shu)導(dao)線制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)狀的(de)(de)金屬(shu)板制成，叫(jiao)集塵電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)性能受粉(fen)塵性質(zhi)、設備(bei)構造(zao)和煙(yan)氣(qi)流(liu)速等(deng)三個因素的(de)(de)影響(xiang)。粉(fen)塵的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵效率有(you)直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵粒難以保(bao)持在(zai)集塵電(dian)(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到(dao)達集塵電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出(chu)，在(zai)塵層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產生局部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造(zao)成除(chu)塵效率下降。

電(dian)(dian)除塵(chen)器的(de)基本(ben)原理是利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主要包括以下(xia)四(si)個相互有關的(de)物理過程(cheng): (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)捕集。
