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)除塵器(qi)是(shi)以靜電(dian)(dian)(dian)凈(jing)化(hua)法來收捕(bu)廢氣(qi)(qi)(qi)中(zhong)的(de)粉(fen)(fen)塵，它(ta)的(de)凈(jing)化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀兩(liang)個系統來完成的(de)，當含(han)塵氣(qi)(qi)(qi)體進人(ren)(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)能(neng)較(jiao)(jiao)均勻(yun)地進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴(kuo)大(da)的(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)速(su)度(du)迅(xun)速(su)降低，其(qi)中(zhong)有(you)些(xie)較(jiao)(jiao)重的(de)塵粒便失去速(su)度(du)而(er)沉(chen)降下來。進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)含(han)塵氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)通(tong)人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)體中(zhong)存(cun)在(zai)大(da)量的(de)電(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)子和(he)離子與進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)粉(fen)(fen)塵結合起來，使(shi)塵粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)作(zuo)用下趨向本設備陽(yang)極(ji)(正(zheng)極(ji)、本設備采用負高(gao)壓制)和(he)陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分(fen)別沉(chen)積(ji)在(zai)相應的(de)電(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設備陰陽(yang)極(ji)振打系統的(de)振打，使(shi)沉(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)粉(fen)(fen)塵振落，進人(ren)(ren)集灰斗 通(tong)過排灰裝置放(fang)出，回收有(you)物料，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)。

工(gong)作(zuo)原(yuan)理

靜(jing)電(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用(yong)高(gao)壓(ya)(ya)電(dian)場使(shi)煙氣發生電(dian)離，氣流中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)在(zai)電(dian)場作(zuo)用(yong)下與(yu)氣流分(fen)離。負極(ji)由不同斷面形狀的(de)(de)(de)金屬(shu)導(dao)線制(zhi)成，叫放電(dian)電(dian)極(ji)。正(zheng)極(ji)由不同幾(ji)何(he)形狀的(de)(de)(de)金屬(shu)板制(zhi)成，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)極(ji)。靜(jing)電(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受(shou)粉(fen)塵(chen)(chen)(chen)性質、設備構(gou)造和煙氣流速等三個(ge)因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)阻是(shi)評價(jia)導(dao)電(dian)性的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率有直接(jie)的(de)(de)(de)影響。比電(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)極(ji)上，致使(shi)其重返氣流。比電(dian)阻過(guo)高(gao)，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)荷(he)不易放出，在(zai)塵(chen)(chen)(chen)層(ceng)之(zhi)間(jian)形成電(dian)壓(ya)(ya)梯度會產生局部擊穿和放電(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)除塵(chen)器的基(ji)本原理是(shi)利(li)用電(dian)力捕集煙(yan)氣中的粉塵(chen)，主要包括(kuo)以(yi)下四個相互(hu)有關(guan)的物理過(guo)程: (1) 氣體的電(dian)離。(2) 粉塵(chen)的荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉塵(chen)向電(dian)極移動。(4) 荷(he)(he)電(dian)粉塵(chen)的捕集。
