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)除(chu)塵器(qi)是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收(shou)捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵，它的(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個系統(tong)來完成的(de)(de)(de)，當含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)流分(fen)布板以及(ji)折流板的(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)(qi)流能較均(jun)勻地進人電(dian)(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大的(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)(qi)(qi)流速(su)度(du)迅速(su)降(jiang)低(di)，其中有些(xie)較重的(de)(de)(de)塵粒(li)便失(shi)去速(su)度(du)而沉降(jiang)下(xia)(xia)來。進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附(fu)近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中存在大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵結合起(qi)來，使(shi)塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下(xia)(xia)趨(qu)向本設(she)(she)(she)備(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)(she)(she)備(bei)采用負高(gao)壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設(she)(she)(she)備(bei)陰陽極(ji)(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉積(ji)在陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵振(zhen)落(luo)，進人集灰斗 通(tong)過排灰裝置放出，回(hui)收(shou)有物(wu)料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工(gong)作原(yuan)理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)工(gong)作原理(li)是利(li)用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣(qi)流(liu)(liu)分離。負極(ji)由不(bu)同斷(duan)面形狀的(de)(de)金屬(shu)導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀的(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)性能受粉(fen)塵(chen)(chen)性質(zhi)、設(she)備構造和煙氣(qi)流(liu)(liu)速等三(san)個(ge)因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效率(lv)有直接(jie)的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高(gao)，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層之(zhi)間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情(qing)況都會(hui)造成(cheng)除(chu)塵(chen)(chen)效率(lv)下降。

電除(chu)塵(chen)器(qi)的(de)(de)基本原理是利用電力捕(bu)集煙氣中的(de)(de)粉(fen)塵(chen)，主要(yao)包括(kuo)以下四個相(xiang)互有關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電離。(2) 粉(fen)塵(chen)的(de)(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動。(4) 荷電粉(fen)塵(chen)的(de)(de)捕(bu)集。
