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(wo)式(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法來(lai)收捕廢氣(qi)中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工(gong)作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)(chen)(chen)淀兩(liang)個系統來(lai)完成的(de)(de)(de)，當含塵(chen)氣(qi)體進(jin)人氣(qi)刺(ci)叭時，含塵(chen)氣(qi)體受到氣(qi)流分布板以(yi)及折流板的(de)(de)(de)調整后(hou)，使(shi)(shi)氣(qi)流能較(jiao)均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)流速(su)度(du)迅速(su)降低，其中有些較(jiao)重的(de)(de)(de)塵(chen)粒便(bian)失(shi)去速(su)度(du)而沉(chen)(chen)(chen)降下(xia)來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)體由(you)于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)體中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和離(li)子與進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)結合起來(lai)，使(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作用(yong)下(xia)趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用(yong)負(fu)高壓制)和陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備(bei)陰陽極(ji)振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使(shi)(shi)沉(chen)(chen)(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)人集灰斗 通(tong)過(guo)排灰裝置(zhi)放(fang)出，回(hui)收有物(wu)料(liao)，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)體排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原(yuan)理是(shi)利(li)用高壓電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離(li)。負極(ji)由(you)不(bu)同斷(duan)面(mian)形(xing)狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾何(he)形(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性能(neng)受(shou)粉塵(chen)(chen)性質、設備構(gou)造和(he)煙氣流(liu)速等(deng)三個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導(dao)電(dian)(dian)性的(de)(de)(de)指標，它(ta)對(dui)除(chu)(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)粒(li)難以(yi)保(bao)持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)極(ji)上(shang)，致使其重返氣流(liu)。比(bi)(bi)電(dian)(dian)阻(zu)(zu)過(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)荷(he)不(bu)易放(fang)(fang)出(chu)，在(zai)塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會產生局部擊穿和(he)放(fang)(fang)電(dian)(dian)現象。這些(xie)情(qing)況(kuang)都會造成(cheng)除(chu)(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵器(qi)的(de)(de)基本原(yuan)理(li)是利用(yong)電(dian)(dian)力(li)捕(bu)集(ji)(ji)煙氣(qi)中的(de)(de)粉(fen)塵，主要包括(kuo)以(yi)下(xia)四(si)個相互有關的(de)(de)物理(li)過程: (1) 氣(qi)體(ti)的(de)(de)電(dian)(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵的(de)(de)捕(bu)集(ji)(ji)。
