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(wo)式(shi)靜電(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工作上(shang)要(yao)是依靠電(dian)(dian)暈極(ji)(ji)(ji)和沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度(du)迅(xun)速(su)降(jiang)低(di)，其(qi)中有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速(su)度(du)而沉(chen)降(jiang)下(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和離(li)(li)子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)(de)作用(yong)(yong)下(xia)趨(qu)向本(ben)設(she)備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備采用(yong)(yong)負高壓(ya)制(zhi))和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設(she)備陰陽(yang)極(ji)(ji)(ji)振打系(xi)統的(de)(de)(de)(de)振打，使(shi)沉(chen)積在(zai)(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)集灰(hui)(hui)斗 通(tong)過排灰(hui)(hui)裝置放出，回收有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)工(gong)作原理(li)是(shi)利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流(liu)分離。負極由不(bu)同斷面形狀的(de)金(jin)屬導(dao)線(xian)制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形狀的(de)金(jin)屬板(ban)制成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備(bei)構造(zao)和(he)煙氣(qi)流(liu)速(su)等三(san)個(ge)因素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難(nan)以(yi)保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)，致使(shi)其(qi)重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)(fang)出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵器的(de)基本原(yuan)理是(shi)利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)(fen)塵，主要(yao)包括以下四個相互有關的(de)物理過程(cheng): (1) 氣體(ti)的(de)電(dian)(dian)離(li)。(2) 粉(fen)(fen)塵的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)粉(fen)(fen)塵的(de)捕集。
