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)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈(jing)(jing)化(hua)法(fa)來(lai)收(shou)捕廢氣(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作上要(yao)是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩(liang)個系(xi)統來(lai)完(wan)成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)流(liu)能較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)作用(yong)(yong)下，氣(qi)流(liu)速(su)度迅(xun)速(su)降(jiang)低(di)，其(qi)中(zhong)有些(xie)較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度而沉(chen)降(jiang)下來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)(yong)下趨向(xiang)本(ben)(ben)設(she)備陽極(ji)(正極(ji)、本(ben)(ben)設(she)備采用(yong)(yong)負高壓(ya)制)和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積(ji)在(zai)(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通過(guo)設(she)備陰(yin)陽極(ji)振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使(shi)沉(chen)積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗 通過(guo)排(pai)灰裝置放出，回收(shou)有物料，被(bei))凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工(gong)作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流中的(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣流分離(li)。負(fu)極由不(bu)同斷(duan)面形(xing)狀的(de)金(jin)屬(shu)導(dao)線(xian)制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)狀的(de)金(jin)屬(shu)板(ban)制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣流速等(deng)三個因素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保(bao)持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致(zhi)使(shi)其重返氣流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)塵(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)(hui)產生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成(cheng)除塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵(chen)器的(de)基本(ben)原理是(shi)利用電(dian)(dian)力捕集(ji)煙氣(qi)中(zhong)的(de)粉塵(chen)，主要包括(kuo)以下四個相互有關(guan)的(de)物理過(guo)程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉塵(chen)的(de)捕集(ji)。
