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)除塵(chen)(chen)器(qi)是以靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法(fa)來收(shou)捕廢氣中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工作上要是依靠電(dian)(dian)(dian)暈(yun)極和(he)沉(chen)(chen)淀兩個(ge)系統來完(wan)成的(de)(de)(de)，當含塵(chen)(chen)氣體(ti)(ti)進(jin)(jin)人(ren)氣刺叭時，含塵(chen)(chen)氣體(ti)(ti)受(shou)到氣流(liu)分布板以及(ji)折流(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣流(liu)能(neng)較均勻(yun)地進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)作用下，氣流(liu)速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)有些(xie)較重的(de)(de)(de)塵(chen)(chen)粒便失去速(su)度而沉(chen)(chen)降(jiang)下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)氣體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極通(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極附(fu)近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣體(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣體(ti)(ti)中(zhong)存在(zai)(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用下趨向本設(she)備陽(yang)極(正極、本設(she)備采(cai)用負高壓(ya)制)和(he)陰極(負極) ， 釋放出電(dian)(dian)(dian)子(zi)分別(bie)沉(chen)(chen)積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)極上，通(tong)過(guo)設(she)備陰陽(yang)極振(zhen)打系統的(de)(de)(de)振(zhen)打，使(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極上的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)落(luo)，進(jin)(jin)人(ren)集灰斗 通(tong)過(guo)排灰裝置放出，回收(shou)有物(wu)料，被(bei))凈(jing)化(hua)的(de)(de)(de)氣體(ti)(ti)排入大氣。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)場(chang)(chang)使(shi)煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)(chang)作用(yong)下與(yu)氣流分離。負(fu)極由(you)不(bu)同斷面(mian)形狀(zhuang)的(de)金屬(shu)導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同幾何形狀(zhuang)的(de)金屬(shu)板(ban)制(zhi)成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和煙氣流速等三(san)個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是評(ping)價導電(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)塵(chen)(chen)效(xiao)率有直接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使(shi)其重返氣流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵(chen)(chen)器的(de)基本原(yuan)理是(shi)利用電(dian)(dian)力捕集(ji)煙氣中的(de)粉塵(chen)(chen)，主要包括以下四(si)個相(xiang)互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉塵(chen)(chen)的(de)捕集(ji)。
