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)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收(shou)捕廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系(xi)統來完(wan)成的(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體進人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能較(jiao)均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴(kuo)大的(de)(de)(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)流(liu)速(su)度迅(xun)速(su)降低(di)，其中有些(xie)(xie)較(jiao)重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速(su)度而沉降下(xia)(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)高(gao)(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)體中存在大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)(li)子與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用下(xia)(xia)趨向本設備陽極(ji)(正極(ji)、本設備采用負高(gao)(gao)壓制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉積在相應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設備陰(yin)陽極(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進人(ren)集灰斗 通(tong)過(guo)排灰裝置(zhi)放出，回收(shou)有物料，被(bei))凈化的(de)(de)(de)(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工(gong)作原理是(shi)利用(yong)高(gao)壓(ya)電(dian)(dian)場使(shi)煙氣(qi)(qi)發生(sheng)電(dian)(dian)離，氣(qi)(qi)流中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用(yong)下與氣(qi)(qi)流分離。負極由(you)(you)不同(tong)斷面形狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極。正極由(you)(you)不同(tong)幾何形狀的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性能受粉(fen)(fen)塵(chen)(chen)(chen)性質、設備(bei)構造(zao)和煙氣(qi)(qi)流速等三個因素的(de)(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻是(shi)評(ping)價導(dao)電(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)極上(shang)，致(zhi)使(shi)其重返氣(qi)(qi)流。比電(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不易放(fang)(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)現(xian)象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)效率下降(jiang)。

電除塵器的(de)基本原理是(shi)利用(yong)電力捕(bu)集煙(yan)氣中的(de)粉(fen)塵，主要(yao)包括(kuo)以下四個(ge)相互有(you)關的(de)物理過程(cheng): (1) 氣體的(de)電離。(2) 粉(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)塵向電極移(yi)動。(4) 荷(he)電粉(fen)塵的(de)捕(bu)集。
