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。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)工作原理(li)是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)中的(de)(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)(qi)流(liu)分離。負(fu)極(ji)(ji)由(you)不同斷面形狀(zhuang)的(de)(de)金屬(shu)導(dao)線制成(cheng)，叫(jiao)放電(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(zhuang)的(de)(de)金屬(shu)板(ban)制成(cheng)，叫(jiao)集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)性能受(shou)粉塵(chen)性質、設(she)備構造和煙(yan)氣(qi)(qi)(qi)流(liu)速等三個因素(su)的(de)(de)影(ying)響。粉塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)效率(lv)有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難(nan)以(yi)保持在集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)效率(lv)下降。

電(dian)除塵(chen)器的基本原(yuan)理是利用電(dian)力捕集(ji)煙氣中的粉(fen)塵(chen)，主要(yao)包括以下四個相互有關的物理過程: (1) 氣體(ti)的電(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向(xiang)電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵(chen)的捕集(ji)。
