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)式靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)凈化(hua)法來收捕廢氣(qi)中(zhong)(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作上(shang)要(yao)是(shi)依靠電(dian)(dian)暈極(ji)和沉(chen)(chen)淀兩(liang)個系統來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)進(jin)人(ren)(ren)氣(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分(fen)布板(ban)以(yi)及(ji)折流(liu)(liu)板(ban)的(de)(de)(de)(de)調整后(hou)，使(shi)(shi)(shi)氣(qi)流(liu)(liu)能較(jiao)均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)流(liu)(liu)速(su)(su)度(du)迅速(su)(su)降低(di)，其中(zhong)(zhong)有些(xie)較(jiao)重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)便失去速(su)(su)度(du)而沉(chen)(chen)降下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)，則(ze)在(zai)電(dian)(dian)暈極(ji)附近(jin)產生電(dian)(dian)暈現象(xiang)，使(shi)(shi)(shi)氣(qi)體(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)體(ti)中(zhong)(zhong)存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)子和離子，這些(xie)電(dian)(dian)子和離子與進(jin)人(ren)(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)結(jie)合(he)起來，使(shi)(shi)(shi)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒(li)(li)在(zai)電(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下(xia)趨向本(ben)(ben)設備陽極(ji)(正極(ji)、本(ben)(ben)設備采用(yong)負高壓(ya)制(zhi))和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子分(fen)別沉(chen)(chen)積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設備陰陽極(ji)振打系統的(de)(de)(de)(de)振打，使(shi)(shi)(shi)沉(chen)(chen)積(ji)在(zai)陰陽電(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)振落，進(jin)人(ren)(ren)集(ji)灰斗 通(tong)過(guo)排灰裝置(zhi)放出，回收有物料(liao)，被(bei))凈化(hua)的(de)(de)(de)(de)氣(qi)體(ti)排入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)工作(zuo)原理(li)是利用高壓電(dian)(dian)場使煙(yan)(yan)氣發生電(dian)(dian)離，氣流中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作(zuo)用下(xia)(xia)與(yu)氣流分(fen)離。負極(ji)(ji)由(you)不同斷面形(xing)狀的(de)金屬導線制成(cheng)(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形(xing)狀的(de)金屬板制成(cheng)(cheng)，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備(bei)構造和(he)煙(yan)(yan)氣流速等三個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)效率有直接的(de)影響。比(bi)(bi)電(dian)(dian)阻過低，塵(chen)(chen)粒難以(yi)保(bao)持(chi)在集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣流。比(bi)(bi)電(dian)(dian)阻過高，到達(da)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)荷不易放出，在塵(chen)(chen)層(ceng)之間形(xing)成(cheng)(cheng)電(dian)(dian)壓梯度會產生局(ju)部擊穿和(he)放電(dian)(dian)現象(xiang)。這些情況都(dou)會造成(cheng)(cheng)除塵(chen)(chen)效率下(xia)(xia)降。

電(dian)(dian)除塵器的(de)(de)(de)基本原理是利用電(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)(de)(de)粉塵，主要包括(kuo)以下四個相互有關(guan)的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)粉塵的(de)(de)(de)捕集(ji)。
