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(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收(shou)(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化(hua)工作上要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉淀兩個(ge)系統來完(wan)成的(de)(de)(de)(de)(de)(de)，當(dang)含塵(chen)(chen)氣(qi)(qi)(qi)體進(jin)人氣(qi)(qi)(qi)刺(ci)叭時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流分布板以及(ji)折流板的(de)(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷(duan)面擴大的(de)(de)(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)流速度迅速降低，其中有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速度而沉降下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(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)(de)(de)(de)氣(qi)(qi)(qi)體中存在(zai)大量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)作用(yong)下趨向(xiang)本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負(fu)高壓(ya)制(zhi))和(he)陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備陰陽(yang)極(ji)(ji)振打系統的(de)(de)(de)(de)(de)(de)振打，使(shi)沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落(luo)，進(jin)人集(ji)灰(hui)斗(dou) 通過排灰(hui)裝(zhuang)置放出，回收(shou)(shou)有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原(yuan)理是(shi)利用高(gao)壓電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離。負(fu)極由不(bu)同斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同幾何(he)形(xing)狀(zhuang)的(de)(de)金(jin)屬(shu)板(ban)制成，叫集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性能(neng)受粉塵(chen)(chen)性質(zhi)、設備構造和煙氣(qi)流速等三個(ge)因(yin)素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有(you)直(zhi)接(jie)的(de)(de)影響。比電(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)粒難以保持(chi)在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)壓梯(ti)度會產(chan)生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)現象。這些情況都會造成除塵(chen)(chen)效(xiao)率下(xia)降。

電(dian)除塵(chen)器的(de)基本原理(li)是利用電(dian)力(li)捕(bu)集煙氣中的(de)粉塵(chen)，主要包括以(yi)下四(si)個(ge)相互有關的(de)物(wu)理(li)過程: (1) 氣體的(de)電(dian)離(li)。(2) 粉塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉塵(chen)向電(dian)極移動(dong)。(4) 荷電(dian)粉塵(chen)的(de)捕(bu)集。
