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)除塵器是(shi)以(yi)靜電(dian)(dian)凈化(hua)法(fa)來(lai)(lai)收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)粉塵，它的(de)(de)凈化(hua)工(gong)作上要是(shi)依靠(kao)電(dian)(dian)暈(yun)極(ji)和沉淀兩個(ge)系(xi)(xi)統來(lai)(lai)完(wan)成的(de)(de)，當含塵氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流分(fen)布板(ban)以(yi)及(ji)折流板(ban)的(de)(de)調(diao)整后，使氣(qi)(qi)(qi)流能較(jiao)均(jun)勻地進人(ren)(ren)電(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷(duan)面(mian)擴大的(de)(de)作用下(xia)，氣(qi)(qi)(qi)流速度(du)迅(xun)速降低，其中有些較(jiao)重的(de)(de)塵粒便失去速度(du)而沉降下(xia)來(lai)(lai)。進人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)含塵氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)暈(yun)極(ji)通(tong)人(ren)(ren)高壓直流電(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)(zai)大量的(de)(de)電(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)粉塵結合起來(lai)(lai)，使塵粒帶電(dian)(dian)，帶電(dian)(dian)塵粒在(zai)(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)作用下(xia)趨向本設(she)備陽極(ji)(正極(ji)、本設(she)備采用負高壓制)和陰極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)子(zi)分(fen)別(bie)沉積在(zai)(zai)(zai)相應的(de)(de)電(dian)(dian)極(ji)上，通(tong)過設(she)備陰陽極(ji)振(zhen)打(da)系(xi)(xi)統的(de)(de)振(zhen)打(da)，使沉積在(zai)(zai)(zai)陰陽電(dian)(dian)極(ji)上的(de)(de)粉塵振(zhen)落，進人(ren)(ren)集灰(hui)(hui)斗 通(tong)過排(pai)灰(hui)(hui)裝置放(fang)出(chu)，回收有物料，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)。

工作(zuo)原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作原理(li)是利用高壓電(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)分離(li)。負極(ji)(ji)由(you)不(bu)同斷(duan)面(mian)形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)同幾何(he)形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)板制成(cheng)，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性能受(shou)粉塵(chen)(chen)性質、設(she)備構造(zao)和煙氣(qi)流(liu)速等三個因(yin)素(su)的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對(dui)除(chu)塵(chen)(chen)效率有(you)直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持(chi)在(zai)集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出(chu)，在(zai)塵(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除(chu)塵(chen)(chen)效率下降。

電(dian)除塵(chen)器的(de)基本(ben)原理是(shi)利用電(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主要包括以(yi)下四(si)個相互(hu)有(you)關的(de)物理過程: (1) 氣體的(de)電(dian)離(li)。(2) 粉(fen)塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)捕集。
