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)除(chu)塵(chen)(chen)(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)凈(jing)化(hua)法來(lai)收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工作上要是(shi)依(yi)靠電(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀兩個(ge)系(xi)統(tong)(tong)來(lai)完成的(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體進人氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)調(diao)整后(hou)(hou)，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均(jun)勻地進人電(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)便(bian)失去(qu)速(su)度而沉(chen)降下(xia)來(lai)。進人電(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)暈(yun)極(ji)(ji)通人高壓直流(liu)(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)離，電(dian)(dian)離后(hou)(hou)的(de)(de)(de)氣(qi)(qi)(qi)體中存在(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)子(zi)和離子(zi)，這(zhe)些電(dian)(dian)子(zi)和離子(zi)與進人電(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合(he)起(qi)來(lai)，使(shi)塵(chen)(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)場(chang)力(li)的(de)(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)高壓制(zhi))和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分別(bie)沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)上，通過設備(bei)陰(yin)陽極(ji)(ji)振(zhen)(zhen)打(da)系(xi)統(tong)(tong)的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進人集灰(hui)斗 通過排灰(hui)裝(zhuang)置放(fang)出，回收(shou)有物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體排入大(da)(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作原理是利用(yong)高(gao)壓電(dian)(dian)場(chang)使(shi)煙氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場(chang)作用(yong)下與氣(qi)(qi)流(liu)分離。負極由(you)不同(tong)斷面形狀的(de)(de)金屬(shu)導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極。正極由(you)不同(tong)幾何形狀的(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)性(xing)能(neng)受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備(bei)構造(zao)和(he)煙氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)阻是評(ping)價導電(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率(lv)(lv)有直接的(de)(de)影(ying)(ying)響。比(bi)(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保(bao)持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)極上，致使(shi)其重(zhong)返氣(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)阻過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會產生局(ju)部擊穿和(he)放(fang)電(dian)(dian)現(xian)象。這(zhe)些情況都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率(lv)(lv)下降。

電(dian)(dian)除塵器(qi)的(de)(de)基本原(yuan)理是利用電(dian)(dian)力捕集煙氣中的(de)(de)粉塵，主要包括以(yi)下四個相互有關的(de)(de)物理過(guo)程: (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉塵的(de)(de)捕集。
