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)式靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)(lai)收(shou)捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工(gong)作上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉淀兩個系統來(lai)(lai)完成的(de)(de)(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)刺(ci)叭(ba)時，含塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以(yi)及折流板的(de)(de)(de)(de)調整后(hou)，使氣(qi)(qi)流能較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大(da)的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流速度(du)迅速降低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速度(du)而沉降下(xia)來(lai)(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存(cun)在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)子和離子與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結(jie)合起來(lai)(lai)，使塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下(xia)趨向(xiang)本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用負(fu)高壓制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別(bie)沉積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設(she)備(bei)陰(yin)陽極(ji)振打系統的(de)(de)(de)(de)振打，使沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振落，進人(ren)(ren)集灰(hui)斗(dou) 通過(guo)排灰(hui)裝置(zhi)放(fang)出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大(da)氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)除塵器的(de)(de)(de)(de)(de)工作原(yuan)理(li)是(shi)利用高壓電(dian)(dian)(dian)場使(shi)(shi)煙氣發生電(dian)(dian)(dian)離(li)，氣流中的(de)(de)(de)(de)(de)粉(fen)塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣流分(fen)離(li)。負極(ji)(ji)由(you)(you)不同(tong)斷面(mian)形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬(shu)導線(xian)制(zhi)成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)(you)不同(tong)幾何(he)形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬(shu)板制(zhi)成，叫(jiao)集(ji)塵電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵器的(de)(de)(de)(de)(de)性能(neng)受粉(fen)塵性質、設備(bei)構造和(he)煙氣流速(su)等三(san)個因素的(de)(de)(de)(de)(de)影響。粉(fen)塵的(de)(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標，它對除塵效率有直接的(de)(de)(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵粒(li)難(nan)以(yi)保持在集(ji)塵電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)(shi)其重(zhong)返氣流。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)塵粒(li)電(dian)(dian)(dian)荷不易(yi)放出，在塵層之間形成電(dian)(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿(chuan)和(he)放電(dian)(dian)(dian)現象。這些情況都會造成除塵效率下降。

電除(chu)塵器的(de)(de)(de)基本原理(li)是利用(yong)電力捕集(ji)煙(yan)氣中的(de)(de)(de)粉(fen)塵，主要(yao)包(bao)括以下四個相互有關的(de)(de)(de)物理(li)過程: (1) 氣體的(de)(de)(de)電離。(2) 粉(fen)塵的(de)(de)(de)荷電。(3) 荷電粉(fen)塵向電極移(yi)動。(4) 荷電粉(fen)塵的(de)(de)(de)捕集(ji)。
