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)除塵器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉塵，它的(de)(de)(de)凈(jing)化(hua)工作上要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩個系統來(lai)(lai)完成(cheng)的(de)(de)(de)，當含(han)(han)塵氣(qi)(qi)體(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭(ba)時(shi)，含(han)(han)塵氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分布(bu)板(ban)以(yi)及折(zhe)流(liu)(liu)板(ban)的(de)(de)(de)調(diao)整后(hou)，使(shi)(shi)氣(qi)(qi)流(liu)(liu)能較均(jun)勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面(mian)擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速度(du)(du)迅速降低，其(qi)中(zhong)有些較重的(de)(de)(de)塵粒(li)(li)便失去(qu)速度(du)(du)而沉降下(xia)來(lai)(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)(han)塵氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵結合起(qi)來(lai)(lai)，使(shi)(shi)塵粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵粒(li)(li)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下(xia)趨向本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負(fu)(fu)高壓制)和陰極(ji)(ji)(負(fu)(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉積(ji)在(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備陰陽極(ji)(ji)振打(da)(da)系統的(de)(de)(de)振打(da)(da)，使(shi)(shi)沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉塵振落，進(jin)人(ren)(ren)(ren)集灰斗 通(tong)過排(pai)(pai)灰裝置放出，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排(pai)(pai)入(ru)大氣(qi)(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)原(yuan)理是(shi)利用高壓電(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)用下與氣(qi)流分(fen)離(li)。負極(ji)由不(bu)同斷(duan)面(mian)形狀(zhuang)的(de)(de)金屬(shu)導線(xian)制成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾(ji)何形狀(zhuang)的(de)(de)金屬(shu)板(ban)制成，叫(jiao)集塵(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造和(he)(he)煙(yan)氣(qi)流速等三(san)個因素的(de)(de)影(ying)響(xiang)(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影(ying)響(xiang)(xiang)。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難以保(bao)持(chi)在集塵(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)流。比電(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放出(chu)，在塵(chen)(chen)層(ceng)之間形成電(dian)(dian)壓梯度會(hui)(hui)產生局部擊穿和(he)(he)放電(dian)(dian)現(xian)象。這些情況都會(hui)(hui)造成除塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵(chen)器的基本(ben)原理(li)是(shi)利(li)用電(dian)力捕集煙氣(qi)中的粉(fen)(fen)塵(chen)，主要包括以下四個(ge)相互(hu)有關的物理(li)過程: (1) 氣(qi)體的電(dian)離。(2) 粉(fen)(fen)塵(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)的捕集。
