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(jing)電(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)凈(jing)化工作上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺(ci)叭時，含塵(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流分布(bu)板以及折(zhe)流板的(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)流能較均勻(yun)地進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)(de)作用(yong)下(xia)(xia)，氣(qi)(qi)流速度(du)迅速降低(di)，其中有些較重的(de)(de)(de)(de)塵(chen)粒(li)便失去速度(du)而沉降下(xia)(xia)來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高(gao)壓(ya)直流電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)體(ti)中存在(zai)(zai)大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)結合起來(lai)(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用(yong)下(xia)(xia)趨向本(ben)設(she)備(bei)陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負(fu)(fu)高(gao)壓(ya)制)和陰(yin)極(ji)(ji)(負(fu)(fu)極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分別沉積(ji)在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設(she)備(bei)陰(yin)陽極(ji)(ji)振打系統(tong)的(de)(de)(de)(de)振打，使沉積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)振落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置放出(chu)，回收(shou)有物料，被)凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的工作原理(li)是利用高壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流中(zhong)的粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下(xia)與氣(qi)流分(fen)離。負極由(you)不(bu)同斷面形(xing)(xing)狀的金屬導線制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形(xing)(xing)狀的金屬板制(zhi)成，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的性能受粉(fen)塵(chen)(chen)性質、設備構(gou)造和煙氣(qi)流速等三個(ge)因素(su)的影響。粉(fen)塵(chen)(chen)的比(bi)電(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)性的指標，它對除(chu)塵(chen)(chen)效率(lv)有直接(jie)的影響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣(qi)流。比(bi)電(dian)(dian)(dian)阻過高，到(dao)達集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不(bu)易放出(chu)，在塵(chen)(chen)層之(zhi)間形(xing)(xing)成電(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放電(dian)(dian)(dian)現象。這些(xie)情(qing)況都(dou)會造成除(chu)塵(chen)(chen)效率(lv)下(xia)降(jiang)。

電(dian)(dian)除塵器的基本原理(li)是利用(yong)電(dian)(dian)力(li)捕集(ji)煙氣中的粉塵，主(zhu)要包(bao)括以下四個相互(hu)有關的物理(li)過程(cheng): (1) 氣體的電(dian)(dian)離。(2) 粉塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)粉塵的捕集(ji)。
