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)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化法來(lai)(lai)(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)和沉淀兩個系統來(lai)(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)體(ti)進人(ren)(ren)(ren)氣(qi)刺叭(ba)時，含塵(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)調(diao)整(zheng)后，使氣(qi)流(liu)(liu)能(neng)較均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)流(liu)(liu)速度迅速降低，其中(zhong)有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速度而(er)沉降下(xia)來(lai)(lai)(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)通(tong)人(ren)(ren)(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)體(ti)中(zhong)存(cun)在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)子和離子與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結合(he)起來(lai)(lai)(lai)，使塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)下(xia)趨向本設(she)備陽(yang)(yang)極(ji)(正極(ji)、本設(she)備采用(yong)負(fu)(fu)高壓制)和陰(yin)極(ji)(負(fu)(fu)極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通(tong)過(guo)設(she)備陰(yin)陽(yang)(yang)極(ji)振打(da)系統的(de)(de)(de)振打(da)，使沉積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振落(luo)，進人(ren)(ren)(ren)集灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放出(chu)，回收有物料，被)凈(jing)(jing)化的(de)(de)(de)氣(qi)體(ti)排入(ru)大(da)氣(qi)。

工作(zuo)原理(li)

靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作原(yuan)理是(shi)利用(yong)高(gao)壓電(dian)(dian)場使(shi)(shi)煙(yan)氣發生(sheng)電(dian)(dian)離，氣流(liu)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)下(xia)與氣流(liu)分離。負極(ji)由(you)(you)不(bu)同斷面形狀的(de)(de)金屬導線(xian)制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正(zheng)極(ji)由(you)(you)不(bu)同幾(ji)何形狀的(de)(de)金屬板(ban)制成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣流(liu)速等三(san)個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使(shi)(shi)其重返氣流(liu)。比(bi)電(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)易放出(chu)，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)壓梯度會(hui)產生(sheng)局(ju)部(bu)擊穿和放電(dian)(dian)現象。這些情(qing)況(kuang)都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下(xia)降(jiang)。

電除(chu)塵(chen)(chen)器的基本原(yuan)理是利(li)用電力(li)捕集(ji)煙(yan)氣(qi)中的粉(fen)(fen)塵(chen)(chen)，主要包括以下四(si)個相互有關的物理過程: (1) 氣(qi)體的電離。(2) 粉(fen)(fen)塵(chen)(chen)的荷(he)電。(3) 荷(he)電粉(fen)(fen)塵(chen)(chen)向電極移動(dong)。(4) 荷(he)電粉(fen)(fen)塵(chen)(chen)的捕集(ji)。
