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)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來(lai)(lai)(lai)收(shou)捕廢氣(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀兩個系(xi)(xi)統來(lai)(lai)(lai)完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)進(jin)人氣(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)分布板(ban)(ban)以及折流(liu)板(ban)(ban)的(de)(de)(de)(de)調整后，使氣(qi)流(liu)能(neng)較均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)(de)作用下，氣(qi)流(liu)速度(du)迅速降低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便失去(qu)速度(du)而沉(chen)降下來(lai)(lai)(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)體(ti)(ti)中(zhong)存在(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)子和離子與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)結合起來(lai)(lai)(lai)，使塵(chen)(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下趨向本(ben)設(she)備陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設(she)備采用負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備陰陽極(ji)(ji)振(zhen)打系(xi)(xi)統的(de)(de)(de)(de)振(zhen)打，使沉(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人集灰斗(dou) 通過排灰裝(zhuang)置(zhi)放出(chu)，回收(shou)有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)(ti)排入大氣(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工(gong)作(zuo)原理是利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)(de)粉塵(chen)(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(qi)流(liu)分離。負(fu)極(ji)由(you)不同(tong)斷面(mian)形狀的(de)(de)(de)金(jin)(jin)屬導線制成(cheng)(cheng)，叫(jiao)(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀的(de)(de)(de)金(jin)(jin)屬板制成(cheng)(cheng)，叫(jiao)(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備(bei)構造和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情(qing)況(kuang)都會造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵(chen)器的(de)(de)基本(ben)原(yuan)理是(shi)利用電(dian)(dian)力(li)捕集煙氣中(zhong)的(de)(de)粉塵(chen)，主要包括以下四個(ge)相(xiang)互有(you)關的(de)(de)物理過程(cheng): (1) 氣體(ti)的(de)(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移(yi)動。(4) 荷(he)(he)電(dian)(dian)粉塵(chen)的(de)(de)捕集。
