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)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)和(he)(he)沉淀(dian)兩個系統來(lai)(lai)完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受(shou)到(dao)氣(qi)(qi)(qi)流(liu)分布板以及(ji)折流(liu)板的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較(jiao)均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)速(su)度迅(xun)速(su)降低，其中有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速(su)度而沉降下來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結(jie)合起來(lai)(lai)，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)作(zuo)用下趨向本設備陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設備采用負(fu)高壓(ya)制)和(he)(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通過設備陰(yin)陽(yang)極(ji)(ji)(ji)(ji)(ji)振打(da)系統的(de)(de)(de)(de)振打(da)，使沉積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)人(ren)集灰斗 通過排灰裝置放出(chu)，回(hui)收有(you)物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工作原(yuan)理

靜電除塵(chen)器的(de)(de)(de)工作原理是利用(yong)高壓(ya)電場使(shi)煙氣(qi)發生電離(li)(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)荷電在電場作用(yong)下與氣(qi)流(liu)分離(li)(li)。負(fu)極由不同斷面形狀的(de)(de)(de)金屬(shu)導線制(zhi)成，叫(jiao)放電電極。正極由不同幾何形狀的(de)(de)(de)金屬(shu)板制(zhi)成，叫(jiao)集(ji)(ji)塵(chen)電極。靜電除塵(chen)器的(de)(de)(de)性能受粉塵(chen)性質(zhi)、設備構(gou)造和煙氣(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)的(de)(de)(de)比電阻是評價導電性的(de)(de)(de)指(zhi)標，它對除塵(chen)效率有(you)直接的(de)(de)(de)影響。比電阻過(guo)低，塵(chen)粒難(nan)以保持在集(ji)(ji)塵(chen)電極上，致使(shi)其(qi)重返氣(qi)流(liu)。比電阻過(guo)高，到達集(ji)(ji)塵(chen)電極的(de)(de)(de)塵(chen)粒電荷不易放出，在塵(chen)層(ceng)之間形成電壓(ya)梯度會(hui)(hui)產生局部擊穿和放電現象(xiang)。這些情況都(dou)會(hui)(hui)造成除塵(chen)效率下降。

電(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)力捕(bu)集煙氣中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相互有(you)關(guan)的(de)物理過程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕(bu)集。
