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(jing)電(dian)(dian)(dian)(dian)(dian)除塵器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法(fa)來(lai)收(shou)捕廢(fei)氣(qi)中(zhong)的(de)(de)(de)粉(fen)塵，它的(de)(de)(de)凈化(hua)(hua)工作(zuo)上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和(he)沉淀(dian)兩(liang)個系統來(lai)完(wan)成的(de)(de)(de)，當含(han)塵氣(qi)體進(jin)(jin)人(ren)(ren)氣(qi)刺叭(ba)時，含(han)塵氣(qi)體受到氣(qi)流分布(bu)板(ban)以及折流板(ban)的(de)(de)(de)調(diao)整后，使氣(qi)流能較(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)流速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)有(you)些較(jiao)重的(de)(de)(de)塵粒便失去(qu)速(su)度而沉降(jiang)下(xia)來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)體中(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵結合起來(lai)，使塵粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用(yong)下(xia)趨向本設(she)(she)備陽(yang)(yang)極(正極、本設(she)(she)備采用(yong)負(fu)高(gao)壓制(zhi))和(he)陰極(負(fu)極) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過(guo)設(she)(she)備陰陽(yang)(yang)極振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)粉(fen)塵振(zhen)(zhen)落，進(jin)(jin)人(ren)(ren)集(ji)灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放出(chu)，回收(shou)有(you)物料，被)凈化(hua)(hua)的(de)(de)(de)氣(qi)體排入大氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)工(gong)作原理是(shi)(shi)利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用(yong)下與(yu)氣流(liu)(liu)(liu)分離。負極由不(bu)同斷面形狀的(de)(de)(de)金(jin)屬導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何(he)形狀的(de)(de)(de)金(jin)屬板制成，叫(jiao)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備(bei)構(gou)造(zao)和煙(yan)氣流(liu)(liu)(liu)速等三個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)(shi)評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率(lv)有(you)直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其(qi)重返氣流(liu)(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情況都會造(zao)成除塵(chen)(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的(de)基本原理是利用電(dian)力捕集煙氣(qi)中(zhong)的(de)粉(fen)塵，主要包括以下四個相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉(fen)塵的(de)荷(he)(he)(he)電(dian)。(3) 荷(he)(he)(he)電(dian)粉(fen)塵向(xiang)電(dian)極移動。(4) 荷(he)(he)(he)電(dian)粉(fen)塵的(de)捕集。
