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)除(chu)塵(chen)(chen)器是以靜電(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)，它的(de)凈化工(gong)作上(shang)(shang)(shang)要是依靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和沉(chen)(chen)淀兩(liang)個系(xi)(xi)統(tong)來(lai)完成(cheng)的(de)，當(dang)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分布(bu)板(ban)以及折流板(ban)的(de)調整后(hou)，使氣(qi)(qi)(qi)流能較均(jun)勻地進(jin)人(ren)電(dian)(dian)場。在(zai)橫斷面擴大的(de)作用下，氣(qi)(qi)(qi)流速度迅速降(jiang)低，其(qi)中(zhong)有些(xie)較重的(de)塵(chen)(chen)粒便(bian)失去速度而沉(chen)(chen)降(jiang)下來(lai)。進(jin)人(ren)電(dian)(dian)場的(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)暈(yun)現象(xiang)，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后(hou)的(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在(zai)大量(liang)的(de)電(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)人(ren)電(dian)(dian)場的(de)粉(fen)塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)場力(li)的(de)作用下趨向本設備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備采(cai)用負高壓制)和陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分別(bie)沉(chen)(chen)積(ji)在(zai)相應的(de)電(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)，通過設備陰陽極(ji)(ji)(ji)(ji)振(zhen)打(da)系(xi)(xi)統(tong)的(de)振(zhen)打(da)，使沉(chen)(chen)積(ji)在(zai)陰陽電(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)的(de)粉(fen)塵(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通過排灰裝置放(fang)出，回收有物(wu)料，被)凈化的(de)氣(qi)(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中(zhong)的粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與(yu)氣(qi)(qi)流分離(li)。負(fu)極(ji)由(you)不(bu)同斷面(mian)形(xing)(xing)狀的金屬導(dao)線制(zhi)成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾何(he)形(xing)(xing)狀的金屬板制(zhi)成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的性能受粉(fen)塵(chen)(chen)性質、設(she)備構造(zao)和煙氣(qi)(qi)流速等(deng)三個因素的影響。粉(fen)塵(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性的指標，它(ta)對除(chu)塵(chen)(chen)效率有直接(jie)的影響。比(bi)電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒(li)(li)難以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重(zhong)返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷不(bu)易(yi)放(fang)(fang)出，在塵(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成除(chu)塵(chen)(chen)效率下降。

電(dian)除塵(chen)器的(de)(de)(de)(de)基(ji)本原理(li)是(shi)利(li)用(yong)電(dian)力捕集煙氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，主要包括(kuo)以下四個相互有關的(de)(de)(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)(de)(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)(de)(de)(de)捕集。
