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。

臥式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法(fa)來收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)粉塵(chen)(chen)，它的(de)凈(jing)化(hua)(hua)工作上要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀兩個系(xi)統來完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體進(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)(qi)流分布板(ban)(ban)以及折(zhe)流板(ban)(ban)的(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)流能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴(kuo)大的(de)作用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流速度(du)(du)迅速降低，其中有些較重的(de)塵(chen)(chen)粒便失去速度(du)(du)而沉(chen)降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)(qi)(qi)體中存在(zai)(zai)大量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)作用(yong)下趨(qu)向本設備(bei)陽極(ji)(正(zheng)極(ji)、本設備(bei)采用(yong)負高壓(ya)制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設備(bei)陰(yin)陽極(ji)振打系(xi)統的(de)振打，使沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)(chen)振落，進(jin)人(ren)集(ji)灰斗 通(tong)過排灰裝置放出，回收(shou)有物料，被)凈(jing)化(hua)(hua)的(de)氣(qi)(qi)(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜電(dian)除(chu)塵(chen)(chen)(chen)器的(de)工作原理(li)是利用高壓(ya)電(dian)場(chang)使煙(yan)氣(qi)發生電(dian)離，氣(qi)流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)在電(dian)場(chang)作用下與氣(qi)流(liu)分(fen)離。負(fu)極(ji)由(you)不同斷面形狀(zhuang)的(de)金(jin)屬(shu)導線制(zhi)成(cheng)，叫(jiao)放電(dian)電(dian)極(ji)。正極(ji)由(you)不同幾(ji)何形狀(zhuang)的(de)金(jin)屬(shu)板制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)(chen)器的(de)性(xing)能(neng)受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙(yan)氣(qi)流(liu)速等(deng)三(san)個因(yin)素(su)的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)阻(zu)是評價導電(dian)性(xing)的(de)指標，它對除(chu)塵(chen)(chen)(chen)效率(lv)有直(zhi)接(jie)的(de)影響。比電(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)電(dian)極(ji)上，致(zhi)使其(qi)重返(fan)氣(qi)流(liu)。比電(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)荷(he)不易放出，在塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)壓(ya)梯度會產生局部擊穿和放電(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的基本(ben)原理是利用電(dian)(dian)(dian)力捕集(ji)煙氣(qi)中的粉塵(chen)(chen)，主要包(bao)括(kuo)以下四個相(xiang)互有關的物理過程: (1) 氣(qi)體的電(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)(dian)粉塵(chen)(chen)的捕集(ji)。
