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(wo)式靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)凈化(hua)工(gong)作(zuo)(zuo)上要(yao)是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)(chen)淀兩個系統(tong)來完成的(de)(de)(de)(de)(de)，當含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)體進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布板以及折流(liu)(liu)(liu)板的(de)(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷(duan)面擴大的(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速度(du)迅速降低，其中(zhong)有(you)些較(jiao)重(zhong)的(de)(de)(de)(de)(de)塵(chen)粒便失去速度(du)而沉(chen)(chen)降下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)(han)塵(chen)氣(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存在(zai)(zai)(zai)大量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這(zhe)些電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉塵(chen)結合起來，使塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下趨(qu)向本設(she)備(bei)陽(yang)(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備(bei)采用(yong)負(fu)高壓制)和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積在(zai)(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設(she)備(bei)陰陽(yang)(yang)極(ji)(ji)振打(da)系統(tong)的(de)(de)(de)(de)(de)振打(da)，使沉(chen)(chen)積在(zai)(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)粉塵(chen)振落，進(jin)人(ren)(ren)集灰斗(dou) 通(tong)過排灰裝置放出，回收有(you)物料(liao)，被(bei))凈化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入(ru)大氣(qi)(qi)(qi)(qi)。

工(gong)作原(yuan)理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工作原(yuan)理(li)是利用高壓電(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)離，氣(qi)流(liu)中的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流(liu)分離。負(fu)極由不同(tong)斷面形狀(zhuang)的金屬(shu)導(dao)線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)電(dian)(dian)極。正極由不同(tong)幾何形狀(zhuang)的金屬(shu)板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性能受粉(fen)塵(chen)(chen)(chen)性質、設備(bei)構造(zao)和(he)煙氣(qi)流(liu)速等(deng)三個因素(su)的影響(xiang)。粉(fen)塵(chen)(chen)(chen)的比電(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)性的指(zhi)標，它對(dui)除(chu)塵(chen)(chen)(chen)效率有直接的影響(xiang)。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)難以(yi)保(bao)持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重(zhong)返氣(qi)流(liu)。比電(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會(hui)(hui)產生局(ju)部擊穿和(he)放(fang)電(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)基本原(yuan)理是利用電(dian)(dian)(dian)力(li)捕集(ji)煙氣(qi)中的(de)粉(fen)(fen)塵(chen)，主要包(bao)括以下四個(ge)相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕集(ji)。
