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)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)凈化工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極和沉淀兩個系統(tong)來(lai)完(wan)成(cheng)的(de)(de)，當含塵(chen)(chen)(chen)(chen)氣體(ti)(ti)進人(ren)氣刺叭時，含塵(chen)(chen)(chen)(chen)氣體(ti)(ti)受到氣流分布(bu)板以及折(zhe)流板的(de)(de)調整后(hou)，使(shi)氣流能(neng)較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷(duan)面(mian)擴大(da)的(de)(de)作用下(xia)，氣流速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)有些較重(zhong)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去(qu)速(su)度而(er)沉降(jiang)下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)氣體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極通人(ren)高壓(ya)直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使(shi)氣體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣體(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)(chen)結合(he)起來(lai)，使(shi)塵(chen)(chen)(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)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下(xia)趨向本(ben)設備陽極(正極、本(ben)設備采用負高壓(ya)制(zhi))和陰(yin)(yin)極(負極) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)，通過設備陰(yin)(yin)陽極振打(da)系統(tong)的(de)(de)振打(da)，使(shi)沉積在(zai)(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)粉塵(chen)(chen)(chen)(chen)振落，進人(ren)集灰斗 通過排灰裝置放出，回收有物(wu)料，被(bei))凈化的(de)(de)氣體(ti)(ti)排入大(da)氣。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流分(fen)離(li)。負極(ji)由不同(tong)斷面形(xing)狀的(de)金(jin)屬(shu)導線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)狀的(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)性能受粉(fen)塵(chen)性質、設備(bei)構造和(he)(he)煙(yan)氣(qi)流速等三個因素的(de)影響。粉(fen)塵(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對(dui)除塵(chen)效(xiao)率(lv)有(you)直接的(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保持(chi)在(zai)(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出(chu)，在(zai)(zai)塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和(he)(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)效(xiao)率(lv)下降。

電(dian)除(chu)塵(chen)器(qi)的(de)(de)基本原理(li)是利用電(dian)力捕集煙(yan)氣(qi)中(zhong)的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下(xia)四個相互有關的(de)(de)物理(li)過程(cheng): (1) 氣(qi)體的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)向電(dian)極移(yi)動。(4) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集。
