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(jing)電(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)(de)工作原(yuan)理是利用高壓(ya)電(dian)(dian)場(chang)使(shi)煙氣發生(sheng)電(dian)(dian)離，氣流(liu)中的(de)(de)(de)(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬導線制成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬板制成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)(de)性能(neng)受粉塵(chen)性質、設備構造和煙氣流(liu)速等(deng)三個因素的(de)(de)(de)(de)影響(xiang)。粉塵(chen)的(de)(de)(de)(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性的(de)(de)(de)(de)指標，它對除(chu)塵(chen)效率(lv)有直接(jie)的(de)(de)(de)(de)影響(xiang)。比電(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)粒難(nan)以保持在集塵(chen)電(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣流(liu)。比電(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)電(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)粒電(dian)(dian)荷不易放出(chu)，在塵(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)壓(ya)梯度會(hui)(hui)產生(sheng)局部擊穿和放電(dian)(dian)現象。這些情況(kuang)都會(hui)(hui)造成(cheng)除(chu)塵(chen)效率(lv)下降(jiang)。

電(dian)除塵(chen)器的(de)(de)基本(ben)原理是(shi)利用電(dian)力捕集煙(yan)氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)，主要包(bao)括以下四個相互有關的(de)(de)物理過(guo)程: (1) 氣(qi)體的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集。
