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)除塵(chen)器(qi)是(shi)(shi)以(yi)靜電(dian)(dian)凈(jing)化法(fa)來收捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈(jing)化工作(zuo)上要是(shi)(shi)依靠電(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個(ge)系統來完成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分布(bu)板以(yi)及折流板的(de)(de)(de)(de)調整后，使氣(qi)(qi)流能(neng)較(jiao)均勻地(di)進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)場。在(zai)橫斷面(mian)擴大(da)的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)流速度迅速降低，其(qi)中有些較(jiao)重的(de)(de)(de)(de)塵(chen)粒(li)便失去速度而沉(chen)降下來。進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高(gao)壓直(zhi)流電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)暈(yun)現(xian)象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)(li)(li)，電(dian)(dian)離(li)(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)子(zi)(zi)和離(li)(li)(li)子(zi)(zi)，這些電(dian)(dian)子(zi)(zi)和離(li)(li)(li)子(zi)(zi)與進(jin)(jin)(jin)人(ren)(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)結合起來，使塵(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本設(she)備(bei)陽(yang)極(ji)(正極(ji)、本設(she)備(bei)采用負高(gao)壓制(zhi))和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)分別(bie)沉(chen)積在(zai)相(xiang)應(ying)的(de)(de)(de)(de)電(dian)(dian)極(ji)上，通過設(she)備(bei)陰陽(yang)極(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使沉(chen)積在(zai)陰陽(yang)電(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)(jin)(jin)人(ren)(ren)集灰斗 通過排(pai)灰裝置(zhi)放出，回收有物料，被)凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入(ru)大(da)氣(qi)(qi)。

工作原(yuan)理(li)

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵器的(de)工作(zuo)原理是利用(yong)高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)中(zhong)的(de)粉(fen)塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣(qi)流(liu)分離。負極(ji)由不(bu)同(tong)斷面形(xing)狀的(de)金(jin)屬(shu)導線(xian)制成(cheng)(cheng)(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形(xing)狀的(de)金(jin)屬(shu)板制成(cheng)(cheng)(cheng)，叫集(ji)(ji)塵電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵器的(de)性能受(shou)粉(fen)塵性質、設(she)備構造(zao)和煙氣(qi)流(liu)速等(deng)三(san)個因素的(de)影響(xiang)。粉(fen)塵的(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)塵效率有(you)直接的(de)影響(xiang)。比電(dian)(dian)(dian)阻過低，塵粒(li)難以(yi)保持在集(ji)(ji)塵電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)(ji)塵電(dian)(dian)(dian)極(ji)的(de)塵粒(li)電(dian)(dian)(dian)荷不(bu)易(yi)放出，在塵層(ceng)之(zhi)間(jian)形(xing)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局(ju)部擊穿(chuan)和放電(dian)(dian)(dian)現(xian)象(xiang)。這(zhe)些情況都會(hui)造(zao)成(cheng)(cheng)(cheng)除(chu)(chu)塵效率下降。

電(dian)(dian)除塵(chen)器的基本原理是利(li)用電(dian)(dian)力捕集(ji)煙氣中的粉(fen)塵(chen)，主要包括以下四個相互有關的物理過程: (1) 氣體的電(dian)(dian)離。(2) 粉(fen)塵(chen)的荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)的捕集(ji)。
