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)除塵器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收(shou)捕廢(fei)氣(qi)中的(de)(de)(de)粉(fen)塵，它的(de)(de)(de)凈(jing)化工作上要是依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)(chen)淀兩個系(xi)統(tong)(tong)來(lai)(lai)完成的(de)(de)(de)，當含(han)(han)塵氣(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)刺叭時，含(han)(han)塵氣(qi)體(ti)(ti)受到氣(qi)流分(fen)布板以(yi)及折(zhe)流板的(de)(de)(de)調整(zheng)后(hou)，使氣(qi)流能(neng)較(jiao)均(jun)勻地進(jin)(jin)人(ren)電(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)(su)度迅速(su)(su)降低，其中有些較(jiao)重的(de)(de)(de)塵粒便失去速(su)(su)度而(er)沉(chen)(chen)降下(xia)來(lai)(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)含(han)(han)塵氣(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)暈極(ji)(ji)通(tong)(tong)人(ren)高壓直流電(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈現象，使氣(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)氣(qi)體(ti)(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和離(li)(li)子，這些電(dian)(dian)(dian)子和離(li)(li)子與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵結合起(qi)來(lai)(lai)，使塵粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒在(zai)(zai)電(dian)(dian)(dian)場力(li)的(de)(de)(de)作用(yong)下(xia)趨向本設(she)備(bei)(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)(bei)采用(yong)負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)子分(fen)別沉(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)(tong)過設(she)備(bei)(bei)陰陽(yang)(yang)極(ji)(ji)振(zhen)打系(xi)統(tong)(tong)的(de)(de)(de)振(zhen)打，使沉(chen)(chen)積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉(fen)塵振(zhen)落，進(jin)(jin)人(ren)集灰(hui)斗 通(tong)(tong)過排灰(hui)裝置放出，回收(shou)有物料，被)凈(jing)化的(de)(de)(de)氣(qi)體(ti)(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣流(liu)分(fen)離(li)。負極(ji)由(you)不(bu)同(tong)斷面形(xing)(xing)狀的(de)(de)金(jin)屬(shu)導線(xian)制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾何形(xing)(xing)狀的(de)(de)金(jin)屬(shu)板(ban)制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)性能受(shou)粉(fen)塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和煙氣流(liu)速等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率有(you)直(zhi)接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)除塵器的(de)(de)基本原(yuan)理(li)是(shi)利用電(dian)力捕集(ji)煙氣中(zhong)的(de)(de)粉塵，主要(yao)包括以(yi)下四個相互有關的(de)(de)物理(li)過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向電(dian)極移動(dong)。(4) 荷(he)電(dian)粉塵的(de)(de)捕集(ji)。
