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(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)工(gong)作原(yuan)理(li)是(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣流(liu)分離。負極(ji)(ji)由不(bu)(bu)同斷面形(xing)狀的(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)(bu)同幾何形(xing)狀的(de)金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設(she)備(bei)構造(zao)(zao)和煙氣流(liu)速等三個因素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指(zhi)標，它對除塵(chen)(chen)效(xiao)率有直接的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)(zai)塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)(zao)成(cheng)除塵(chen)(chen)效(xiao)率下(xia)降。

電除塵(chen)器的(de)基本原理是利用電力捕集煙氣中(zhong)的(de)粉塵(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極移動。(4) 荷(he)電粉塵(chen)的(de)捕集。
