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)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化(hua)工作上(shang)(shang)要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)沉(chen)(chen)淀兩(liang)個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)以及折流(liu)(liu)板(ban)的(de)(de)(de)(de)(de)(de)調(diao)整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷(duan)面擴(kuo)大的(de)(de)(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度(du)迅速降(jiang)低，其中有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失去(qu)速度(du)而沉(chen)(chen)降(jiang)下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中存在(zai)大量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)(de)(de)作用下趨向(xiang)本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用負高壓制)和(he)陰極(ji)(負極(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)過設備(bei)陰陽極(ji)振(zhen)打(da)系(xi)統(tong)的(de)(de)(de)(de)(de)(de)振(zhen)打(da)，使沉(chen)(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進人(ren)集灰(hui)斗 通(tong)過排(pai)灰(hui)裝置放出(chu)(chu)，回收有物(wu)料，被)凈化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)工作原(yuan)理是利用高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)發生(sheng)電(dian)(dian)(dian)離(li)，氣(qi)流中的(de)(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下(xia)與氣(qi)流分離(li)。負(fu)極由不同(tong)斷面形狀的(de)(de)(de)金屬導線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正(zheng)極由不同(tong)幾何(he)形狀的(de)(de)(de)金屬板制成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質(zhi)、設備構造和(he)煙氣(qi)流速(su)等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣(qi)流。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放出(chu)，在塵(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)梯度會(hui)產(chan)生(sheng)局部(bu)擊(ji)穿(chuan)和(he)放電(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)(cheng)除塵(chen)(chen)效(xiao)率下(xia)降。

電(dian)除塵(chen)器的(de)(de)基(ji)本(ben)原理是利用電(dian)力捕集煙氣中的(de)(de)粉塵(chen)，主要包括以(yi)下四個相(xiang)互有關的(de)(de)物(wu)理過程: (1) 氣體的(de)(de)電(dian)離(li)。(2) 粉塵(chen)的(de)(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉塵(chen)向電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉塵(chen)的(de)(de)捕集。
