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)除塵(chen)器是以靜電(dian)(dian)凈(jing)化(hua)法來收(shou)捕廢氣中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈(jing)化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)暈(yun)(yun)極(ji)和沉(chen)淀(dian)兩個系統(tong)來完成的(de)(de)(de)，當(dang)含塵(chen)氣體進人(ren)(ren)(ren)氣刺(ci)叭(ba)時，含塵(chen)氣體受到氣流分(fen)(fen)布板(ban)以及折流板(ban)的(de)(de)(de)調(diao)整(zheng)后(hou)，使(shi)氣流能(neng)較均勻地進人(ren)(ren)(ren)電(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面(mian)擴大(da)(da)的(de)(de)(de)作(zuo)用下，氣流速度迅速降低，其中有(you)些(xie)(xie)較重(zhong)的(de)(de)(de)塵(chen)粒便(bian)失去速度而沉(chen)降下來。進人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)氣體由于電(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)(ren)(ren)高(gao)壓(ya)直流電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)暈(yun)(yun)現象，使(shi)氣體電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)(de)氣體中存在(zai)(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)子(zi)和離子(zi)，這(zhe)些(xie)(xie)電(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下趨向本(ben)設備陽極(ji)(正極(ji)、本(ben)設備采用負高(gao)壓(ya)制)和陰極(ji)(負極(ji)) ， 釋放(fang)(fang)出電(dian)(dian)子(zi)分(fen)(fen)別沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設備陰陽極(ji)振(zhen)(zhen)打(da)系統(tong)的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉(chen)積在(zai)(zai)陰陽電(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進人(ren)(ren)(ren)集灰(hui)斗(dou) 通(tong)過(guo)排(pai)灰(hui)裝置放(fang)(fang)出，回收(shou)有(you)物料(liao)，被)凈(jing)化(hua)的(de)(de)(de)氣體排(pai)入大(da)(da)氣。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原(yuan)理(li)是利用高壓電(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用下(xia)與氣流(liu)分離。負極(ji)(ji)由不同(tong)斷面形(xing)狀的(de)(de)金屬(shu)(shu)導線制成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)狀的(de)(de)金屬(shu)(shu)板制成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性(xing)能受(shou)粉(fen)塵(chen)(chen)性(xing)質、設備構造和(he)煙(yan)氣流(liu)速等三個(ge)因素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有(you)直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低(di)，塵(chen)(chen)粒(li)(li)難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局(ju)部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)效率下(xia)降。

電(dian)除塵(chen)(chen)器的(de)基本原理是(shi)利用(yong)電(dian)力捕集煙氣中的(de)粉塵(chen)(chen)，主要包(bao)括以下四個相互有關(guan)的(de)物理過程(cheng): (1) 氣體的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)(chen)向電(dian)極移動(dong)。(4) 荷電(dian)粉塵(chen)(chen)的(de)捕集。
