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

靜電除(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)(de)(de)工(gong)作原理(li)是利用(yong)(yong)高壓電場(chang)使(shi)煙氣發生電離(li)，氣流(liu)(liu)中的(de)(de)(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電在(zai)(zai)(zai)電場(chang)作用(yong)(yong)下(xia)與氣流(liu)(liu)分離(li)。負極由(you)不同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)(de)(de)(de)金屬導線制成(cheng)(cheng)，叫放(fang)(fang)電電極。正(zheng)極由(you)不同(tong)幾何形(xing)狀(zhuang)的(de)(de)(de)(de)(de)(de)(de)(de)金屬板(ban)制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)電極。靜電除(chu)塵(chen)(chen)器的(de)(de)(de)(de)(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和煙氣流(liu)(liu)速等(deng)三(san)個因素的(de)(de)(de)(de)(de)(de)(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)(de)(de)(de)(de)(de)(de)比電阻(zu)是評價導電性(xing)的(de)(de)(de)(de)(de)(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)效(xiao)(xiao)率有直接的(de)(de)(de)(de)(de)(de)(de)(de)影響(xiang)。比電阻(zu)過低(di)，塵(chen)(chen)粒(li)難以(yi)保持在(zai)(zai)(zai)集(ji)塵(chen)(chen)電極上，致使(shi)其重返氣流(liu)(liu)。比電阻(zu)過高，到達集(ji)塵(chen)(chen)電極的(de)(de)(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)電荷(he)(he)不易放(fang)(fang)出，在(zai)(zai)(zai)塵(chen)(chen)層之間形(xing)成(cheng)(cheng)電壓梯度會(hui)產生局部擊穿和放(fang)(fang)電現象。這些情況都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)(xiao)率下(xia)降。

電(dian)(dian)(dian)(dian)除塵器的(de)基本原理(li)(li)是利用電(dian)(dian)(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)粉(fen)塵，主要包括(kuo)以下四個(ge)相互有關的(de)物理(li)(li)過程(cheng): (1) 氣體(ti)的(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵的(de)捕集(ji)。
