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)(dian)除塵(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈化法(fa)來收捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀(dian)兩個系(xi)統來完(wan)成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及(ji)折流(liu)(liu)板(ban)的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進人電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴(kuo)大的(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降低(di)，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去(qu)速度而沉降下來。進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)子和(he)離(li)子與進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)作用下趨向本(ben)設備(bei)陽極(ji)(正(zheng)極(ji)、本(ben)設備(bei)采(cai)用負高壓制(zhi))和(he)陰極(ji)(負極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)子分別(bie)沉積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備(bei)陰陽極(ji)振打(da)系(xi)統的(de)(de)(de)(de)振打(da)，使沉積在(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振落，進人集灰斗 通(tong)過(guo)排(pai)灰裝置放出(chu)，回收有物(wu)料(liao)，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原(yuan)理是(shi)利用高(gao)壓電(dian)(dian)(dian)場使(shi)煙(yan)氣發生(sheng)(sheng)電(dian)(dian)(dian)離(li)，氣流中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下與氣流分離(li)。負(fu)極(ji)由不(bu)(bu)同(tong)斷面形(xing)(xing)狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)同(tong)幾何形(xing)(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構造(zao)和煙(yan)氣流速等三個因素的(de)(de)(de)影響(xiang)(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)(de)影響(xiang)(xiang)。比(bi)電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣流。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)(bu)易(yi)放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會產生(sheng)(sheng)局(ju)部擊(ji)穿和放電(dian)(dian)(dian)現象(xiang)。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)(chen)器的(de)(de)基本原理是利用電力(li)捕集煙(yan)氣中的(de)(de)粉(fen)塵(chen)(chen)，主要(yao)包(bao)括以下四個相互有關的(de)(de)物(wu)理過程: (1) 氣體的(de)(de)電離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)(chen)向電極移(yi)動。(4) 荷(he)電粉(fen)塵(chen)(chen)的(de)(de)捕集。
