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(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)(lai)(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統(tong)來(lai)(lai)(lai)完(wan)成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)(fen)布板以及(ji)折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能較(jiao)均勻(yun)地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫(heng)斷面擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降低(di)，其中有(you)些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度(du)而(er)沉降下(xia)來(lai)(lai)(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高(gao)(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體中存(cun)在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)(lai)(lai)，使(shi)塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作用下(xia)趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用負高(gao)(gao)壓制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)(fen)別沉積在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設備(bei)陰(yin)陽極(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落(luo)，進人(ren)(ren)集灰(hui)斗 通(tong)過排灰(hui)裝置放出，回收有(you)物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工(gong)作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣流(liu)分離(li)。負極(ji)(ji)由不(bu)同斷面(mian)形狀的(de)金屬(shu)導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾何形狀的(de)金屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)性質、設(she)備構造(zao)和煙(yan)氣流(liu)速(su)等三(san)個因素的(de)影響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指(zhi)標，它對除塵(chen)(chen)(chen)效率有直接的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保(bao)持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致(zhi)使其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)(chen)器的(de)基本(ben)原理是利用電(dian)力捕集(ji)(ji)煙氣(qi)中的(de)粉塵(chen)(chen)，主(zhu)要(yao)包(bao)括(kuo)以下四個相(xiang)互有關的(de)物理過程(cheng): (1) 氣(qi)體的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)(chen)向電(dian)極移動(dong)。(4) 荷(he)電(dian)粉塵(chen)(chen)的(de)捕集(ji)(ji)。
