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(wo)式靜電(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)凈化(hua)法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工(gong)作上(shang)要是(shi)依靠電(dian)(dian)暈極(ji)和(he)(he)(he)沉(chen)淀兩個系統(tong)來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體進(jin)人(ren)氣(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能(neng)較均勻(yun)地進(jin)人(ren)電(dian)(dian)場(chang)。在橫斷面擴大(da)的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去(qu)速(su)度而沉(chen)降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)暈極(ji)通人(ren)高壓直流(liu)(liu)電(dian)(dian)，則在電(dian)(dian)暈極(ji)附(fu)近(jin)產生電(dian)(dian)暈現象，使(shi)氣(qi)(qi)體電(dian)(dian)離(li)，電(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)體中(zhong)存在大(da)量的(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)(he)(he)離(li)子(zi)，這(zhe)些電(dian)(dian)子(zi)和(he)(he)(he)離(li)子(zi)與進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下(xia)趨向本設(she)(she)備陽(yang)極(ji)(正極(ji)、本設(she)(she)備采用負高壓制)和(he)(he)(he)陰(yin)(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子(zi)分別(bie)沉(chen)積(ji)在相應的(de)(de)(de)(de)電(dian)(dian)極(ji)上(shang)，通過(guo)設(she)(she)備陰(yin)(yin)陽(yang)極(ji)振(zhen)打(da)系統(tong)的(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)積(ji)在陰(yin)(yin)陽(yang)電(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置放出，回(hui)收有物料(liao)，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體排入(ru)大(da)氣(qi)(qi)。

工(gong)作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是(shi)利(li)用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下與(yu)氣(qi)流(liu)分離。負極(ji)由不(bu)同(tong)斷面形狀(zhuang)的(de)(de)(de)金屬(shu)導線(xian)制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何(he)形狀(zhuang)的(de)(de)(de)金屬(shu)板制成，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造和煙(yan)氣(qi)流(liu)速等(deng)三個因(yin)素的(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些(xie)情況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)器(qi)的(de)基本(ben)原理是(shi)利(li)用電力捕集煙氣中的(de)粉塵(chen)，主要包括以(yi)下四個(ge)相互有(you)關的(de)物理過程: (1) 氣體的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極移動。(4) 荷(he)電粉塵(chen)的(de)捕集。
