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)(chen)(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化法(fa)來收(shou)捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)(de)凈(jing)化工作上要是依靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和沉(chen)(chen)淀兩個系統來完(wan)成的(de)(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布板以及折(zhe)流(liu)板的(de)(de)(de)(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷(duan)面(mian)擴大(da)的(de)(de)(de)(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中(zhong)有(you)些(xie)較(jiao)重的(de)(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便(bian)失去速(su)度而沉(chen)(chen)降下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)(de)作用下趨向(xiang)本設(she)備陽(yang)(yang)極(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)、本設(she)備采(cai)用負(fu)(fu)高壓制)和陰極(ji)(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別(bie)沉(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)(tong)過(guo)設(she)備陰陽(yang)(yang)極(ji)(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)(de)(de)(de)振打(da)，使(shi)(shi)沉(chen)(chen)積在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集(ji)灰斗 通(tong)(tong)過(guo)排灰裝置放出，回(hui)收(shou)有(you)物料，被)凈(jing)化的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發(fa)生電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分(fen)離。負極由(you)(you)不同斷面(mian)形狀的(de)(de)金屬導(dao)線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)(you)不同幾何(he)形狀的(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能(neng)受(shou)粉(fen)塵(chen)(chen)性質、設備構(gou)造和煙氣(qi)流速等三(san)個因素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)效率有直接的(de)(de)影響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易(yi)放出，在(zai)(zai)塵(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生局(ju)部(bu)擊(ji)穿和放電(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造成(cheng)除(chu)塵(chen)(chen)效率下降。

電除(chu)塵(chen)器的基本原理(li)是利用(yong)電力(li)捕(bu)集(ji)煙氣中的粉塵(chen)，主要(yao)包(bao)括(kuo)以下四個相(xiang)互(hu)有(you)關的物理(li)過程: (1) 氣體(ti)的電離。(2) 粉塵(chen)的荷電。(3) 荷電粉塵(chen)向(xiang)電極移(yi)動。(4) 荷電粉塵(chen)的捕(bu)集(ji)。
