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)除塵(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化法(fa)來收捕廢氣(qi)(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化工作(zuo)(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈(yun)極和(he)沉(chen)淀(dian)兩個系(xi)統來完成(cheng)的(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)(ren)(ren)氣(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)流(liu)能較(jiao)均(jun)勻地進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷(duan)面擴大的(de)(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)流(liu)速度(du)迅速降(jiang)低，其(qi)中有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度(du)而沉(chen)降(jiang)下來。進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)極通人(ren)(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極附近產生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離子(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離子(zi)(zi)(zi)與進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)(zuo)用下趨向本(ben)(ben)設(she)(she)備陽(yang)極(正極、本(ben)(ben)設(she)(she)備采用負高壓制)和(he)陰極(負極) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極上，通過設(she)(she)備陰陽(yang)極振(zhen)(zhen)打系(xi)統的(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極上的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)(ren)(ren)(ren)集(ji)灰(hui)斗(dou) 通過排灰(hui)裝置(zhi)放出，回收有物料，被)凈(jing)化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原理是利(li)用(yong)高壓電(dian)(dian)(dian)(dian)場(chang)(chang)使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用(yong)下與氣(qi)流(liu)分離(li)。負極由不(bu)同(tong)斷(duan)面形(xing)狀的(de)(de)(de)金屬導線制(zhi)成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正(zheng)極由不(bu)同(tong)幾何形(xing)狀的(de)(de)(de)金屬板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性能(neng)受(shou)粉塵(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)流(liu)速等三個(ge)因素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使(shi)其重返(fan)氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)層之間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)效(xiao)率下降。

電除塵(chen)器(qi)的(de)基本原理(li)是利用電力捕集煙氣中的(de)粉塵(chen)，主(zhu)要包括以下四個(ge)相互有(you)關(guan)的(de)物理(li)過(guo)程: (1) 氣體(ti)的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極(ji)移動(dong)。(4) 荷(he)電粉塵(chen)的(de)捕集。
