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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作上要是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個系統來(lai)完成的(de)(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)調(diao)整后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在橫斷(duan)面擴大的(de)(de)作用(yong)(yong)下(xia)(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低，其(qi)中(zhong)有些(xie)較重的(de)(de)塵(chen)(chen)粒(li)便失(shi)去速(su)度(du)而沉(chen)降(jiang)下(xia)(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)子(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)(yong)下(xia)(xia)趨向本設(she)備陽(yang)(yang)極(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)、本設(she)備采用(yong)(yong)負高(gao)壓制)和(he)(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)過設(she)備陰陽(yang)(yang)極(ji)(ji)(ji)(ji)振打系統的(de)(de)振打，使沉(chen)積在陰陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落，進人(ren)集灰(hui)斗 通(tong)過排灰(hui)裝置放(fang)出(chu)，回收有物料(liao)，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣流(liu)分離。負極由(you)不(bu)同(tong)斷(duan)面形狀(zhuang)的(de)(de)(de)金屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾何形狀(zhuang)的(de)(de)(de)金屬板制(zhi)成(cheng)(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)(xing)能受粉(fen)(fen)塵(chen)性(xing)(xing)質、設備構造和煙氣流(liu)速等三個因素(su)的(de)(de)(de)影響。粉(fen)(fen)塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它對除塵(chen)效率(lv)有直(zhi)接的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低(di)，塵(chen)粒難以保(bao)持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)極上(shang)，致使(shi)其(qi)重(zhong)返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)(he)不(bu)易放出，在塵(chen)層之(zhi)間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些(xie)情況(kuang)都會(hui)造成(cheng)(cheng)除塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)(chen)器的基本原理是(shi)利用電(dian)(dian)力(li)捕集煙氣中(zhong)的粉塵(chen)(chen)(chen)，主要(yao)包括以下四(si)個相(xiang)互(hu)有關的物理過程: (1) 氣體的電(dian)(dian)離(li)。(2) 粉塵(chen)(chen)(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉塵(chen)(chen)(chen)的捕集。
