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。

臥式靜電(dian)(dian)(dian)除塵(chen)器(qi)是以靜電(dian)(dian)(dian)凈化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上要(yao)是依(yi)靠電(dian)(dian)(dian)暈極(ji)和沉(chen)淀(dian)兩個系統(tong)來(lai)完成的(de)(de)(de)(de)，當(dang)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)流(liu)(liu)能(neng)較均勻地(di)進(jin)(jin)人電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速度(du)迅速降(jiang)低，其中有些較重的(de)(de)(de)(de)塵(chen)粒便(bian)失去速度(du)而(er)沉(chen)降(jiang)下(xia)來(lai)。進(jin)(jin)人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈極(ji)通(tong)人高壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)子和離子與進(jin)(jin)人電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)結(jie)合(he)起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨(qu)向本(ben)設備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設備(bei)采(cai)用(yong)負高壓制)和陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉(chen)積在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備(bei)陰(yin)(yin)陽(yang)極(ji)振打(da)系統(tong)的(de)(de)(de)(de)振打(da)，使沉(chen)積在(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振落，進(jin)(jin)人集灰(hui)斗(dou) 通(tong)過(guo)排灰(hui)裝置放出，回收有物料(liao)，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)流分離。負極(ji)由不(bu)(bu)同斷面形狀的(de)(de)金屬導(dao)線(xian)制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)同幾何形狀的(de)(de)金屬板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)(qi)流速(su)等三個因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)(bu)易放出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會造成除(chu)塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本原理是(shi)利用(yong)電(dian)(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互有關的(de)物(wu)理過(guo)程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕集。
