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(gong)作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作原理是(shi)利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與氣流(liu)分離(li)。負極由不(bu)同(tong)斷面形(xing)狀的(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正(zheng)極由不(bu)同(tong)幾何形(xing)狀的(de)(de)金(jin)屬板制成(cheng)，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)性(xing)(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)(xing)質、設備構(gou)造(zao)和煙氣流(liu)速等三個因素的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接(jie)的(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致(zhi)使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在塵(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產生局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降(jiang)。

電(dian)(dian)除塵器的(de)(de)基(ji)本(ben)原理是利用電(dian)(dian)力(li)捕(bu)集(ji)(ji)煙氣(qi)中的(de)(de)粉塵，主要包括以下四個相互有(you)關的(de)(de)物(wu)理過(guo)程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極(ji)移動(dong)。(4) 荷(he)電(dian)(dian)粉塵的(de)(de)捕(bu)集(ji)(ji)。
