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)(dian)除塵器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)(hua)法來收捕廢氣(qi)中的(de)(de)(de)(de)(de)(de)粉塵，它的(de)(de)(de)(de)(de)(de)凈(jing)化(hua)(hua)(hua)工作上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉(chen)淀兩個系(xi)統來完成的(de)(de)(de)(de)(de)(de)，當含(han)(han)塵氣(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)刺叭時，含(han)(han)塵氣(qi)體(ti)(ti)(ti)受到(dao)氣(qi)流分布板(ban)以及折流板(ban)的(de)(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作用下，氣(qi)流速(su)度迅速(su)降低，其中有些較重的(de)(de)(de)(de)(de)(de)塵粒(li)便(bian)失去速(su)度而沉(chen)降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含(han)(han)塵氣(qi)體(ti)(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵結合起來，使(shi)塵粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作用下趨向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采(cai)用負(fu)(fu)高壓制)和陰極(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備陰陽極(ji)(ji)(ji)振打系(xi)統的(de)(de)(de)(de)(de)(de)振打，使(shi)沉(chen)積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉塵振落(luo)，進(jin)人(ren)集灰(hui)(hui)斗 通過排灰(hui)(hui)裝置放出，回收有物料(liao)，被(bei))凈(jing)化(hua)(hua)(hua)的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入大(da)氣(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理是(shi)(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)(liu)分離。負(fu)極(ji)(ji)由(you)(you)不同斷面形(xing)狀的(de)(de)(de)金(jin)(jin)屬(shu)導(dao)線(xian)制成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)(you)不同幾何形(xing)狀的(de)(de)(de)金(jin)(jin)屬(shu)板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性能(neng)受(shou)粉塵(chen)(chen)性質(zhi)、設備構造和煙氣(qi)流(liu)(liu)速等三個(ge)因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)(shi)評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它(ta)對除(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在塵(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)除塵(chen)(chen)器的基本原理(li)是(shi)利用電(dian)(dian)(dian)力捕(bu)集煙氣中的粉(fen)塵(chen)(chen)，主要包括以下四個(ge)相(xiang)互有(you)關(guan)的物(wu)理(li)過(guo)程: (1) 氣體的電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕(bu)集。
