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(chen)(chen)器是(shi)以靜電(dian)(dian)凈(jing)化(hua)(hua)法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工作上要是(shi)依(yi)靠電(dian)(dian)暈(yun)極(ji)和(he)(he)(he)沉(chen)(chen)淀(dian)兩(liang)個(ge)系統(tong)來(lai)完(wan)成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)均勻地進人(ren)電(dian)(dian)場(chang)。在橫斷(duan)面擴大的(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其中有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失去速度而沉(chen)(chen)降下來(lai)。進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)暈(yun)極(ji)通(tong)人(ren)高(gao)壓直流電(dian)(dian)，則在電(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)暈(yun)現(xian)象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中存在大量的(de)(de)(de)電(dian)(dian)子(zi)(zi)和(he)(he)(he)離(li)子(zi)(zi)，這些(xie)電(dian)(dian)子(zi)(zi)和(he)(he)(he)離(li)子(zi)(zi)與(yu)進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來(lai)，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設(she)備(bei)采用負高(gao)壓制)和(he)(he)(he)陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積在相(xiang)應的(de)(de)(de)電(dian)(dian)極(ji)上，通(tong)過(guo)設(she)備(bei)陰(yin)陽(yang)極(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)沉(chen)(chen)積在陰(yin)陽(yang)電(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)集灰斗 通(tong)過(guo)排灰裝置放(fang)出(chu)，回收(shou)有物(wu)料，被(bei))凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作(zuo)原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣(qi)流分離。負極(ji)(ji)由不同斷面形狀的(de)(de)金(jin)屬(shu)導線制成(cheng)(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何(he)形狀的(de)(de)金(jin)屬(shu)板制成(cheng)(cheng)，叫集(ji)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)器的(de)(de)性(xing)能(neng)受(shou)粉(fen)塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造和煙氣(qi)流速等三個因(yin)素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重(zhong)返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率下(xia)降。

電(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)基(ji)本原理是(shi)利用電(dian)(dian)(dian)(dian)力捕集(ji)煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要包(bao)括以下四個(ge)相互有(you)關的(de)物理過程: (1) 氣(qi)體(ti)的(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集(ji)。
