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)式靜電(dian)(dian)(dian)除(chu)塵器是(shi)(shi)以(yi)(yi)靜電(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉塵，它的(de)(de)凈(jing)化工作上(shang)要是(shi)(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系統(tong)來(lai)完成的(de)(de)，當含(han)塵氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵氣(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)布板以(yi)(yi)及折流(liu)板的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流(liu)能(neng)較(jiao)均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)(zai)橫(heng)斷(duan)面擴大的(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度迅(xun)速(su)降低，其(qi)中(zhong)有些(xie)較(jiao)重的(de)(de)塵粒便(bian)失去(qu)速(su)度而沉降下(xia)來(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含(han)塵氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)(ren)高(gao)壓直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產(chan)生電(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)離(li)(li)(li)后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)子和(he)離(li)(li)(li)子，這(zhe)些(xie)電(dian)(dian)(dian)子和(he)離(li)(li)(li)子與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵結合起來(lai)，使塵粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵粒在(zai)(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)作用(yong)下(xia)趨向本設備(bei)陽極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設備(bei)陰陽極(ji)(ji)振(zhen)打(da)系統(tong)的(de)(de)振(zhen)打(da)，使沉積在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵振(zhen)落，進(jin)人(ren)(ren)(ren)集(ji)灰斗(dou) 通(tong)過排灰裝置放(fang)出，回收有物料，被(bei))凈(jing)化的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工(gong)作原理是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流分離(li)。負(fu)極(ji)由(you)不同(tong)斷面形(xing)(xing)狀的(de)金屬(shu)導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形(xing)(xing)狀的(de)金屬(shu)板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造和(he)煙氣(qi)流速(su)等三個因素的(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率有(you)直接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒(li)難以(yi)保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)除(chu)塵器的(de)基本原理是利(li)用(yong)電(dian)力捕集煙氣中的(de)粉(fen)(fen)塵，主要包括(kuo)以下四個相互有關的(de)物理過(guo)程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)(fen)塵的(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)(fen)塵的(de)捕集。
