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)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)中的(de)(de)粉塵(chen)，它的(de)(de)凈化(hua)工作上要(yao)是依靠電(dian)(dian)(dian)(dian)暈(yun)極和(he)沉(chen)淀兩(liang)個系統(tong)來(lai)完成的(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)刺叭時，含塵(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)(liu)分布(bu)板以及折(zhe)流(liu)(liu)板的(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)能(neng)較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴(kuo)大的(de)(de)作用(yong)(yong)下，氣(qi)流(liu)(liu)速度(du)迅速降低，其(qi)中有(you)些較重的(de)(de)塵(chen)粒便(bian)失(shi)去速度(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極附近(jin)產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)體(ti)(ti)(ti)中存在大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)結合起來(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用(yong)(yong)下趨(qu)向(xiang)本(ben)設備(bei)陽極(正極、本(ben)設備(bei)采用(yong)(yong)負(fu)高壓制)和(he)陰(yin)極(負(fu)極) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)極上，通(tong)過設備(bei)陰(yin)陽極振打(da)系統(tong)的(de)(de)振打(da)，使(shi)沉(chen)積在陰(yin)陽電(dian)(dian)(dian)(dian)極上的(de)(de)粉塵(chen)振落，進(jin)人(ren)集(ji)灰斗 通(tong)過排灰裝置放出(chu)，回收有(you)物料，被)凈化(hua)的(de)(de)氣(qi)體(ti)(ti)(ti)排入大氣(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理是(shi)利用(yong)(yong)高壓電(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)(yong)下與(yu)氣(qi)流分(fen)離。負(fu)極由(you)不同斷面(mian)形(xing)狀(zhuang)的(de)(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不同幾何(he)形(xing)狀(zhuang)的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)性質、設備構造(zao)和煙氣(qi)流速等(deng)三個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使(shi)其重(zhong)返氣(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)產生局部擊穿(chuan)和放電(dian)(dian)(dian)現象。這些情(qing)況都會(hui)造(zao)成(cheng)除(chu)塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)基本原(yuan)理是利用電(dian)(dian)(dian)力捕集(ji)煙氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下(xia)四(si)個(ge)相互有(you)關的(de)(de)物(wu)理過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)(dian)離(li)。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)。
