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(jing)電(dian)(dian)(dian)(dian)除塵(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收捕(bu)廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工作上要是依靠電(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)體進(jin)人氣(qi)(qi)刺(ci)叭時，含塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流分布板以(yi)及折流板的(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)流能較(jiao)均(jun)勻地進(jin)人電(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷面擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流速度(du)迅(xun)速降低，其中有些(xie)較(jiao)重的(de)(de)(de)塵(chen)粒便失去速度(du)而(er)沉降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈極(ji)通人高(gao)壓直流電(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)體中存在(zai)(zai)(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)結合(he)起(qi)來，使(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下(xia)趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用(yong)負(fu)高(gao)壓制(zhi))和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別(bie)沉積(ji)在(zai)(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過設備(bei)陰(yin)陽極(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使(shi)沉積(ji)在(zai)(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)振(zhen)落，進(jin)人集灰斗 通過排(pai)灰裝(zhuang)置放出，回收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)體排(pai)入大氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)工作原(yuan)理是(shi)利用高壓電(dian)(dian)場使煙氣發生電(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作用下與氣流(liu)分離(li)。負極(ji)(ji)(ji)(ji)由不同(tong)斷面形(xing)狀的(de)(de)金屬導(dao)線(xian)制成(cheng)，叫放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不同(tong)幾何形(xing)狀的(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備構造和煙氣流(liu)速等三個因素的(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)性的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率(lv)有直接的(de)(de)影(ying)響。比電(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，致(zhi)使其重返氣流(liu)。比電(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷(he)不易放(fang)(fang)出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會(hui)產生局(ju)部擊(ji)穿和放(fang)(fang)電(dian)(dian)現(xian)象。這些情(qing)況都會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)效率(lv)下降(jiang)。

電(dian)(dian)(dian)除塵器(qi)的(de)基本原理是(shi)利用電(dian)(dian)(dian)力捕集煙(yan)氣中的(de)粉塵，主(zhu)要包括以下(xia)四個相互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉塵的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉塵的(de)捕集。
