XWD型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(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理(li)是利用高(gao)(gao)壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作用下與氣流分離(li)。負極由不同斷面(mian)形狀的(de)(de)(de)金(jin)屬導(dao)線制(zhi)(zhi)成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同幾何形狀的(de)(de)(de)金(jin)屬板制(zhi)(zhi)成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備(bei)構造和(he)煙氣流速(su)等三(san)個因素的(de)(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重(zhong)返(fan)氣流。比電(dian)(dian)(dian)(dian)阻過高(gao)(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵(chen)器的基(ji)本(ben)原理是利用電(dian)(dian)力捕集(ji)煙氣中的粉(fen)(fen)塵(chen)，主要包括以下四個相互有(you)關的物理過程: (1) 氣體(ti)的電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)的捕集(ji)。
