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)除塵(chen)(chen)(chen)(chen)器(qi)是以靜(jing)電(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)(chen)(chen)，它的(de)凈(jing)化工(gong)作(zuo)上要是依靠電(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩(liang)個系統(tong)來完成(cheng)的(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)(qi)流分布(bu)板以及折(zhe)流板的(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)(qi)流能較均勻地進人(ren)電(dian)場(chang)(chang)(chang)。在(zai)(zai)橫斷面擴(kuo)大的(de)作(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其(qi)中(zhong)有些較重的(de)塵(chen)(chen)(chen)(chen)粒便失去速度而沉降下來。進人(ren)電(dian)場(chang)(chang)(chang)的(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)高壓直流電(dian)，則在(zai)(zai)電(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)離，電(dian)離后的(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大量的(de)電(dian)子(zi)和(he)離子(zi)，這些電(dian)子(zi)和(he)離子(zi)與進人(ren)電(dian)場(chang)(chang)(chang)的(de)粉塵(chen)(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)(chen)粒在(zai)(zai)電(dian)場(chang)(chang)(chang)力的(de)作(zuo)用(yong)下趨向本(ben)(ben)設(she)備(bei)(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)(ben)設(she)備(bei)(bei)采(cai)用(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)子(zi)分別(bie)沉積在(zai)(zai)相(xiang)應的(de)電(dian)極(ji)(ji)(ji)上，通(tong)過設(she)備(bei)(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)打系統(tong)的(de)振(zhen)打，使沉積在(zai)(zai)陰(yin)陽電(dian)極(ji)(ji)(ji)上的(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)集灰斗(dou) 通(tong)過排灰裝置(zhi)放出，回收有物料，被)凈(jing)化的(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣流(liu)分離(li)。負極由不同斷面形狀的(de)(de)金屬導(dao)線制成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同幾何形狀的(de)(de)金屬板制成，叫集塵(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)性能(neng)受粉塵(chen)性質、設備構造和煙氣流(liu)速等三(san)個(ge)因素的(de)(de)影響(xiang)。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)效率有直接(jie)的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保持在集塵(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)層之間形成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造成除(chu)塵(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)(chen)器的基本原理是利用電(dian)(dian)(dian)力捕集煙氣中的粉(fen)塵(chen)(chen)，主要包括以下(xia)四個相互(hu)有(you)關的物理過程: (1) 氣體(ti)的電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕集。
