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(shi)靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)(jin)(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)調整(zheng)后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻(yun)地(di)進(jin)(jin)(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降(jiang)低(di)，其中(zhong)有些較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度而(er)沉(chen)(chen)降(jiang)下(xia)來(lai)。進(jin)(jin)(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)子(zi)和離子(zi)與(yu)進(jin)(jin)(jin)(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下(xia)趨向本(ben)設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負(fu)高壓制)和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子(zi)分別沉(chen)(chen)積在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設備陰(yin)陽(yang)極(ji)(ji)振打系(xi)統的(de)(de)(de)振打，使沉(chen)(chen)積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)(jin)(jin)(jin)(jin)人(ren)(ren)(ren)集灰斗 通(tong)(tong)過排灰裝(zhuang)置放(fang)出(chu)，回收有物(wu)料(liao)，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原(yuan)理(li)是利(li)用高壓電(dian)(dian)場使(shi)(shi)煙(yan)氣(qi)(qi)發生電(dian)(dian)離(li)，氣(qi)(qi)流(liu)(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用下(xia)與氣(qi)(qi)流(liu)(liu)分離(li)。負極由不(bu)同(tong)(tong)斷面形(xing)(xing)狀的(de)(de)(de)金屬導(dao)(dao)線(xian)制(zhi)成，叫(jiao)(jiao)放(fang)電(dian)(dian)電(dian)(dian)極。正極由不(bu)同(tong)(tong)幾何形(xing)(xing)狀的(de)(de)(de)金屬板(ban)制(zhi)成，叫(jiao)(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)性能受(shou)粉塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和煙(yan)氣(qi)(qi)流(liu)(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻是評(ping)價導(dao)(dao)電(dian)(dian)性的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)(de)影響。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極上(shang)，致(zhi)使(shi)(shi)其(qi)重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)阻過(guo)高，到達(da)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)壓梯度會產生局部(bu)擊穿和放(fang)電(dian)(dian)現象(xiang)。這些(xie)情況都(dou)會造成除塵(chen)(chen)(chen)(chen)(chen)效率(lv)下(xia)降。

電(dian)除塵器(qi)的(de)基本原(yuan)理(li)是利用(yong)電(dian)力捕集煙(yan)氣(qi)中的(de)粉(fen)塵，主要包括以下四個相互有(you)關的(de)物理(li)過(guo)程: (1) 氣(qi)體的(de)電(dian)離(li)。(2) 粉(fen)塵的(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)塵向電(dian)極移動(dong)。(4) 荷(he)(he)電(dian)粉(fen)塵的(de)捕集。
