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

靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)場使煙(yan)氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作(zuo)用下與氣(qi)(qi)流(liu)(liu)分離。負極(ji)(ji)由不同(tong)斷面形狀的(de)(de)金屬導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形狀的(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造(zao)和煙(yan)氣(qi)(qi)流(liu)(liu)速等(deng)三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的(de)(de)指標(biao)，它對(dui)除塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)(li)難以保持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會產生局部(bu)擊穿和放(fang)電(dian)(dian)現象。這些情(qing)況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵器的(de)(de)基(ji)本原理是利(li)用(yong)電(dian)(dian)(dian)力捕集煙氣中(zhong)的(de)(de)粉(fen)塵，主要(yao)包括(kuo)以下四(si)個相互有關(guan)的(de)(de)物理過(guo)程: (1) 氣體(ti)(ti)的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)(de)捕集。
