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)除(chu)塵(chen)器是以(yi)(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)淀兩個系統(tong)來完(wan)成的(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分布(bu)板以(yi)(yi)及折流(liu)板的(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴(kuo)大的(de)(de)(de)作用下，氣(qi)(qi)流(liu)速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)(zhong)有些(xie)較重的(de)(de)(de)塵(chen)粒便(bian)失(shi)去速(su)度而沉(chen)降(jiang)下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)(zhong)存(cun)在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)結合(he)起(qi)來，使塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向本設(she)備陽(yang)極(ji)(正極(ji)、本設(she)備采用負高壓(ya)制)和陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)(tong)過(guo)設(she)備陰(yin)(yin)陽(yang)極(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使沉(chen)積在(zai)(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進(jin)人(ren)集灰斗 通(tong)(tong)過(guo)排灰裝(zhuang)置放出，回(hui)收(shou)有物料，被)凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作原理是利用高(gao)壓電(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作用下與氣流(liu)分離(li)。負(fu)極由不同斷(duan)面形(xing)狀的(de)(de)(de)(de)金屬導線(xian)制(zhi)成(cheng)，叫放電(dian)(dian)電(dian)(dian)極。正極由不同幾何形(xing)狀的(de)(de)(de)(de)金屬板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和(he)煙氣流(liu)速等三個因素(su)的(de)(de)(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性的(de)(de)(de)(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持(chi)在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重返氣流(liu)。比電(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷(he)不易放出(chu)，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會(hui)產生(sheng)局部(bu)擊穿和(he)放電(dian)(dian)現(xian)象。這些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)除塵(chen)(chen)器的基本(ben)原(yuan)理是利用電(dian)力(li)捕集(ji)煙(yan)氣中的粉(fen)塵(chen)(chen)，主(zhu)要包括(kuo)以下四個相(xiang)互有關的物理過(guo)程: (1) 氣體的電(dian)離。(2) 粉(fen)塵(chen)(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)(chen)的捕集(ji)。
