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)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)，它的(de)凈(jing)(jing)化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和沉(chen)淀兩個(ge)系(xi)統(tong)來完成的(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)流分布板以(yi)及折流板的(de)調整后，使氣(qi)(qi)(qi)(qi)流能較(jiao)均勻(yun)地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴大的(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)流速(su)度(du)迅速(su)降(jiang)低，其(qi)中(zhong)有些較(jiao)重的(de)塵(chen)(chen)粒(li)便失去速(su)度(du)而沉(chen)降(jiang)下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)結合起(qi)來，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)作(zuo)用下(xia)趨(qu)向本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設(she)備(bei)采用負(fu)高壓(ya)(ya)制)和陰(yin)極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)振(zhen)(zhen)打系(xi)統(tong)的(de)振(zhen)(zhen)打，使沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)粉(fen)塵(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放出，回收有物料，被)凈(jing)(jing)化的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作(zuo)原理是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)(qi)流(liu)分(fen)離(li)。負極由(you)不同斷面形(xing)狀的(de)金屬導(dao)線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)不同幾(ji)何(he)形(xing)狀的(de)金屬板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受(shou)粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)(qi)流(liu)速等三個因(yin)素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效率有(you)直接(jie)的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重(zhong)返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在塵(chen)(chen)(chen)層(ceng)之間(jian)形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造(zao)成除塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)除(chu)塵器的(de)(de)基本(ben)原理是利用(yong)電(dian)(dian)力捕(bu)集煙氣中(zhong)的(de)(de)粉塵，主要包(bao)括以(yi)下四個相互有關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)(dian)離(li)。(2) 粉塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)粉塵的(de)(de)捕(bu)集。
