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)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)凈化工(gong)作上要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)(chen)(chen)淀兩(liang)個(ge)系統(tong)(tong)來(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)調整后(hou)(hou)，使氣(qi)(qi)(qi)流(liu)能較(jiao)均勻(yun)地進人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴大(da)的(de)(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降(jiang)低(di)，其中(zhong)有(you)些(xie)較(jiao)重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度而沉(chen)(chen)(chen)降(jiang)下來(lai)。進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存(cun)在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和離(li)子與進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)采用負(fu)高壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)(chen)(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)(zhen)打系統(tong)(tong)的(de)(de)振(zhen)(zhen)打，使沉(chen)(chen)(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進人集灰斗(dou) 通過排(pai)(pai)灰裝(zhuang)置放(fang)出，回收有(you)物料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)(pai)入(ru)大(da)氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)工(gong)作(zuo)原理(li)是利用(yong)高壓(ya)(ya)電(dian)(dian)(dian)(dian)場(chang)(chang)使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉塵荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作(zuo)用(yong)下(xia)與氣(qi)(qi)流(liu)分(fen)離。負極(ji)由不(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)金屬導線制成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形(xing)狀(zhuang)的(de)(de)金屬板制成，叫(jiao)集塵電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)性能(neng)受粉塵性質、設備構造和煙氣(qi)(qi)流(liu)速(su)等三個(ge)因(yin)素的(de)(de)影響。粉塵的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性的(de)(de)指標(biao)，它對除(chu)塵效率有直(zhi)接的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵粒難以保持在(zai)(zai)集塵電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高，到達(da)集塵電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵層之間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會(hui)(hui)造成除(chu)塵效率下(xia)降。

電(dian)除塵(chen)器的(de)基本原理是利用(yong)電(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主(zhu)要包括以下四(si)個相互有關的(de)物(wu)理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動(dong)。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕集。
