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。

工作原理(li)

靜電(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)(de)工作(zuo)原理(li)是(shi)利用高(gao)壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流(liu)(liu)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下(xia)(xia)與(yu)氣(qi)流(liu)(liu)分離(li)。負極(ji)由不同斷面(mian)形狀的(de)(de)(de)(de)金屬(shu)導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同幾何形狀的(de)(de)(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)性(xing)(xing)質、設(she)備構造和(he)(he)煙氣(qi)流(liu)(liu)速等(deng)三個(ge)因素的(de)(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)阻是(shi)評價導電(dian)(dian)性(xing)(xing)的(de)(de)(de)(de)指標，它對除塵(chen)(chen)效率有直接的(de)(de)(de)(de)影(ying)響。比(bi)(bi)電(dian)(dian)阻過低(di)，塵(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)流(liu)(liu)。比(bi)(bi)電(dian)(dian)阻過高(gao)，到(dao)達(da)集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)荷(he)不易放(fang)(fang)出(chu)，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯(ti)度會產(chan)生局(ju)部擊(ji)穿和(he)(he)放(fang)(fang)電(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)效率下(xia)(xia)降(jiang)。

電(dian)(dian)除塵(chen)器的基本(ben)原理是(shi)利用電(dian)(dian)力捕集煙氣中(zhong)的粉塵(chen)，主要包(bao)括以(yi)下四個相(xiang)互有關的物理過程: (1) 氣體(ti)的電(dian)(dian)離。(2) 粉塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的捕集。
