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。

臥式靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)和沉淀兩個系統(tong)來完成(cheng)的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)(qi)流(liu)分布(bu)板以及折流(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能(neng)較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)的(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降(jiang)低，其中有些(xie)(xie)較(jiao)重(zhong)的(de)(de)(de)塵(chen)粒便失去速度而沉降(jiang)下來。進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)通(tong)人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存(cun)在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些(xie)(xie)電(dian)(dian)(dian)(dian)子和離子與進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)塵(chen)結合起(qi)來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下趨向(xiang)本設(she)備陽極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)備采用負高壓(ya)制)和陰(yin)極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)子分別沉積在(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)過(guo)設(she)備陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)振落，進人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝(zhuang)置放出(chu)，回收有物(wu)料，被(bei))凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)原理是利(li)用高壓(ya)電(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣流(liu)分(fen)離。負(fu)極(ji)由不同斷(duan)面形狀(zhuang)的(de)(de)金(jin)屬導線(xian)制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形狀(zhuang)的(de)(de)金(jin)屬板制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設(she)備構造和煙氣流(liu)速等(deng)三(san)個(ge)因素(su)的(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)影(ying)(ying)響。比電(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難以(yi)保(bao)持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返(fan)氣流(liu)。比電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)產(chan)生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造成(cheng)除塵(chen)(chen)(chen)效率(lv)下(xia)降(jiang)。

電(dian)除(chu)塵(chen)器(qi)的基本原理(li)是利用電(dian)力捕集(ji)煙(yan)氣中的粉(fen)塵(chen)，主(zhu)要(yao)包括以下四(si)個相互(hu)有關(guan)的物理(li)過(guo)程(cheng): (1) 氣體(ti)的電(dian)離。(2) 粉(fen)塵(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極(ji)移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的捕集(ji)。
