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。

工作原(yuan)理

靜電(dian)除(chu)塵(chen)(chen)器的(de)工(gong)作原理是(shi)(shi)利(li)用(yong)高(gao)壓電(dian)場(chang)使煙(yan)氣(qi)發(fa)生電(dian)離，氣(qi)流中的(de)粉塵(chen)(chen)荷(he)電(dian)在(zai)電(dian)場(chang)作用(yong)下(xia)與氣(qi)流分(fen)離。負極(ji)由不同(tong)斷面(mian)形狀的(de)金(jin)屬導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由不同(tong)幾何形狀的(de)金(jin)屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)器的(de)性(xing)能受粉塵(chen)(chen)性(xing)質(zhi)、設備構造(zao)和煙(yan)氣(qi)流速等三個(ge)因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)的(de)比(bi)電(dian)阻是(shi)(shi)評價導(dao)電(dian)性(xing)的(de)指標(biao)，它對除(chu)塵(chen)(chen)效率有直接的(de)影(ying)響(xiang)。比(bi)電(dian)阻過低，塵(chen)(chen)粒難(nan)以保持(chi)在(zai)集塵(chen)(chen)電(dian)極(ji)上，致使其重返氣(qi)流。比(bi)電(dian)阻過高(gao)，到(dao)達集塵(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)層之(zhi)間(jian)形成(cheng)電(dian)壓梯度會產(chan)生局部擊(ji)穿和放(fang)電(dian)現象。這些情況都(dou)會造(zao)成(cheng)除(chu)塵(chen)(chen)效率下(xia)降。

電(dian)(dian)除塵(chen)器的(de)(de)(de)(de)基本原(yuan)理(li)是(shi)利用電(dian)(dian)力(li)捕集煙氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)，主要包(bao)括(kuo)以下四個相互有關的(de)(de)(de)(de)物理(li)過(guo)程: (1) 氣(qi)(qi)體的(de)(de)(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)塵(chen)的(de)(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向(xiang)電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)(de)捕集。
