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(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法(fa)來(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化工作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉(chen)淀兩(liang)個(ge)系統來(lai)(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流分布(bu)板以及折流板的(de)(de)(de)(de)調整(zheng)后(hou)，使(shi)(shi)(shi)氣(qi)(qi)(qi)流能(neng)較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面(mian)擴大的(de)(de)(de)(de)作(zuo)(zuo)用下(xia)(xia)，氣(qi)(qi)(qi)流速(su)(su)度迅速(su)(su)降低，其中有些較重的(de)(de)(de)(de)塵(chen)粒(li)便失去速(su)(su)度而沉(chen)降下(xia)(xia)來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存(cun)在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)結合(he)起來(lai)(lai)，使(shi)(shi)(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)(zuo)用下(xia)(xia)趨向本(ben)設(she)(she)備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)(she)備采(cai)用負高(gao)壓制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設(she)(she)備陰(yin)陽極(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使(shi)(shi)(shi)沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)集(ji)灰斗 通過排(pai)灰裝置放(fang)出(chu)，回收有物料(liao)，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原理是利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣流(liu)分離(li)。負極(ji)(ji)由(you)不同斷面形狀的(de)(de)(de)金屬導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形狀的(de)(de)(de)金屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備(bei)構造和(he)(he)煙氣流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難(nan)以保(bao)持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產(chan)生(sheng)局部(bu)擊穿和(he)(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些(xie)情況都會造成除(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)基本原理(li)是利用電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下(xia)四個相(xiang)互有關的(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集。
