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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈化(hua)工作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)淀(dian)兩個系統(tong)來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)體進(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)體受到氣(qi)流(liu)分(fen)布板(ban)以(yi)及(ji)折流(liu)板(ban)的(de)(de)調(diao)整后，使(shi)氣(qi)流(liu)能(neng)較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)作用(yong)下(xia)(xia)，氣(qi)流(liu)速度迅速降低(di)，其中有(you)些較重(zhong)的(de)(de)塵(chen)(chen)粒便失去速度而沉(chen)降下(xia)(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通人(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)體中存(cun)在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用(yong)下(xia)(xia)趨(qu)向(xiang)本(ben)設備(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設備(bei)采用(yong)負(fu)高壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別(bie)沉(chen)積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通過(guo)設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉(chen)積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置放出(chu)，回收(shou)有(you)物料(liao)，被(bei))凈化(hua)的(de)(de)氣(qi)體排入(ru)大(da)氣(qi)。

工(gong)作原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)工作原理是(shi)利(li)用高(gao)壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作用下與氣流分離(li)。負(fu)極由(you)不(bu)同斷面形狀的(de)金屬導(dao)線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形狀的(de)金屬板制成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)性(xing)能(neng)受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備(bei)構造(zao)和(he)煙氣流速等(deng)三個(ge)因素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其(qi)重返(fan)氣流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在塵(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊(ji)穿和(he)放(fang)電(dian)(dian)(dian)(dian)現(xian)象(xiang)。這(zhe)些(xie)情況都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降(jiang)。
