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)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收捕(bu)廢氣(qi)中(zhong)(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作上要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩個系統(tong)(tong)來(lai)(lai)完成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進(jin)(jin)(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)(liu)分布(bu)板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)調整后，使(shi)氣(qi)流(liu)(liu)能較均勻(yun)地進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速(su)度迅(xun)速(su)降低，其中(zhong)(zhong)有些(xie)較重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度而沉(chen)降下來(lai)(lai)。進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)中(zhong)(zhong)存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進(jin)(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下趨向本(ben)設(she)備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負高壓(ya)制)和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設(she)備(bei)陰陽(yang)(yang)極(ji)(ji)(ji)振打系統(tong)(tong)的(de)(de)振打，使(shi)沉(chen)積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)(jin)(jin)人集灰斗 通(tong)過排灰裝置(zhi)放(fang)出，回收有物料(liao)，被)凈(jing)化(hua)的(de)(de)氣(qi)體(ti)排入(ru)大(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)工作(zuo)原(yuan)理是利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)下(xia)與氣(qi)流分離。負(fu)極(ji)由不同(tong)斷(duan)面形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬(shu)(shu)導(dao)線制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何(he)形(xing)(xing)狀(zhuang)的(de)(de)(de)金屬(shu)(shu)板制成，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)性(xing)能受粉塵(chen)性(xing)質、設(she)備構造和煙氣(qi)流速等三個因(yin)素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對除(chu)塵(chen)效率有(you)直接的(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)粒難以保持在(zai)(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)(zai)塵(chen)層之(zhi)間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產(chan)生(sheng)局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造成除(chu)塵(chen)效率下(xia)降。

電除塵(chen)器的(de)基本原(yuan)理是利用電力捕集(ji)煙(yan)氣中的(de)粉塵(chen)，主要(yao)包括(kuo)以下四個相互有關的(de)物理過程: (1) 氣體的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極移動(dong)。(4) 荷(he)電粉塵(chen)的(de)捕集(ji)。
