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)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀(dian)兩(liang)個系統(tong)來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能(neng)較均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面(mian)擴(kuo)大(da)(da)的(de)(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)流(liu)速度(du)迅速降低，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速度(du)而沉(chen)降下(xia)(xia)來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在大(da)(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子與(yu)進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結(jie)合起(qi)來(lai)，使(shi)(shi)塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下(xia)(xia)趨向本(ben)設備(bei)陽極(ji)(正極(ji)、本(ben)設備(bei)采用負高壓制(zhi))和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別(bie)沉(chen)積在相(xiang)應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設備(bei)陰(yin)陽極(ji)振(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)(ren)集灰斗 通過排灰裝置放出，回收有物料(liao)，被(bei))凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大(da)(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原(yuan)理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流(liu)分(fen)離(li)。負極由(you)不(bu)同斷面(mian)形(xing)狀的(de)(de)(de)金屬導(dao)線(xian)制(zhi)成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同幾何(he)形(xing)狀的(de)(de)(de)金屬板制(zhi)成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣(qi)流(liu)速(su)等三個(ge)因素的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對(dui)除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其(qi)重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造成除塵(chen)(chen)(chen)(chen)效(xiao)率(lv)下(xia)降。

電(dian)(dian)除塵(chen)器的(de)基本原理是利用電(dian)(dian)力捕集煙(yan)氣中(zhong)的(de)粉塵(chen)，主(zhu)要(yao)包括以下四個相(xiang)互有關的(de)物理過(guo)程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)向電(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)粉塵(chen)的(de)捕集。
