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(shi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵，它的(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉(chen)(chen)淀兩個(ge)系(xi)統來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分布板以(yi)及(ji)折流(liu)板的(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴(kuo)大的(de)(de)(de)作(zuo)用下(xia)(xia)，氣(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)低(di)，其中有些較重的(de)(de)(de)塵粒(li)便(bian)失(shi)去速度(du)而(er)沉(chen)(chen)降(jiang)下(xia)(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵結(jie)合起來(lai)，使塵粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作(zuo)用下(xia)(xia)趨向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用負高壓制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積(ji)在(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備陰(yin)陽極(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使沉(chen)(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉(fen)塵振(zhen)落，進(jin)人(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置(zhi)放(fang)出(chu)，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入(ru)大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用(yong)下與氣(qi)流分離(li)。負極由(you)不同斷面形狀的(de)金屬導(dao)線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正(zheng)極由(you)不同幾(ji)何形狀的(de)金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設(she)備(bei)構造和(he)煙氣(qi)流速等(deng)三個因素(su)的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率有直接的(de)影(ying)響。比電(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)阻過(guo)(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易(yi)放出(chu)，在(zai)(zai)塵(chen)(chen)(chen)層(ceng)之間(jian)形成(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)現(xian)象。這些情況都會(hui)(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)(de)基本原理(li)是利用電(dian)(dian)力捕集煙氣中的(de)(de)粉(fen)(fen)塵，主要包括以下四個(ge)相互有關的(de)(de)物(wu)理(li)過(guo)程: (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉(fen)(fen)塵的(de)(de)捕集。
