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)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢(fei)氣中(zhong)(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈化(hua)工作上要(yao)是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉(chen)(chen)淀兩個(ge)系(xi)統來完成(cheng)的(de)(de)，當含(han)塵(chen)(chen)氣體進(jin)人(ren)(ren)氣刺叭時，含(han)塵(chen)(chen)氣體受到氣流分布板以(yi)及折(zhe)流板的(de)(de)調整(zheng)后，使氣流能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)。在橫(heng)斷(duan)面擴大(da)的(de)(de)作用(yong)下，氣流速(su)(su)度迅速(su)(su)降低，其中(zhong)(zhong)有(you)些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)粒(li)便失去速(su)(su)度而沉(chen)(chen)降下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)的(de)(de)含(han)塵(chen)(chen)氣體由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈現象(xiang)，使氣體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)氣體中(zhong)(zhong)存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)的(de)(de)粉塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)力的(de)(de)作用(yong)下趨向本(ben)設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備采(cai)用(yong)負(fu)高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備陰(yin)陽(yang)極(ji)(ji)(ji)振打(da)系(xi)統的(de)(de)振打(da)，使沉(chen)(chen)積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落(luo)，進(jin)人(ren)(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置放出(chu)(chu)，回(hui)收有(you)物(wu)料(liao)，被)凈化(hua)的(de)(de)氣體排(pai)入大(da)氣。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)工(gong)作(zuo)原理是利用(yong)(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)(yong)下與(yu)氣(qi)流(liu)分離。負極(ji)由不同斷面(mian)形狀的(de)(de)(de)(de)金屬導線(xian)制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形狀的(de)(de)(de)(de)金屬板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)性能受(shou)粉(fen)塵(chen)(chen)性質、設備(bei)構造和(he)煙(yan)氣(qi)流(liu)速等三個(ge)因素的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指標(biao)，它對(dui)除(chu)(chu)塵(chen)(chen)效(xiao)率有(you)直接(jie)的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難(nan)以保(bao)持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易(yi)放出(chu)，在塵(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)造成除(chu)(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)器的(de)基本原理是利用電(dian)力(li)捕(bu)集(ji)煙(yan)氣(qi)中的(de)粉塵(chen)，主要包括(kuo)以下四(si)個相互有關的(de)物(wu)理過程(cheng): (1) 氣(qi)體(ti)的(de)電(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)的(de)捕(bu)集(ji)。
