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)器是以(yi)靜(jing)電(dian)凈化法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈化工作上要(yao)是依靠電(dian)暈(yun)極(ji)(ji)(ji)(ji)和沉淀兩(liang)個(ge)系(xi)統(tong)來完成的(de)(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)分布板以(yi)及折流(liu)(liu)(liu)板的(de)(de)(de)(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)能(neng)較均勻地進(jin)人(ren)電(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴(kuo)大的(de)(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度(du)(du)迅速(su)降低，其中(zhong)有些(xie)較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去(qu)速(su)度(du)(du)而沉降下來。進(jin)人(ren)電(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)暈(yun)極(ji)(ji)(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)，則在(zai)(zai)電(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)離(li)，電(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大量(liang)的(de)(de)(de)(de)(de)電(dian)子(zi)(zi)和離(li)子(zi)(zi)，這些(xie)電(dian)子(zi)(zi)和離(li)子(zi)(zi)與進(jin)人(ren)電(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來，使(shi)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)力的(de)(de)(de)(de)(de)作用(yong)下趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備(bei)采用(yong)負高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)子(zi)(zi)分別沉積在(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)上，通(tong)過設備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)陽(yang)電(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通(tong)過排灰裝置(zhi)放出(chu)，回收有物(wu)料(liao)，被(bei))凈化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)工作原理是(shi)利(li)用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣流分離。負(fu)極(ji)由不同(tong)斷面形狀(zhuang)(zhuang)的(de)(de)(de)金(jin)(jin)屬導(dao)線(xian)制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形狀(zhuang)(zhuang)的(de)(de)(de)金(jin)(jin)屬板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)性能(neng)受粉塵(chen)(chen)性質、設備構造和煙(yan)氣流速等三個(ge)因素的(de)(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指標(biao)，它(ta)對除塵(chen)(chen)效率有直接的(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒(li)難(nan)以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造成(cheng)除塵(chen)(chen)效率下降。

電(dian)除(chu)塵器的基(ji)本原理是利用電(dian)力捕集煙氣(qi)中(zhong)的粉(fen)塵，主要(yao)包括以下四個相互有關的物理過程: (1) 氣(qi)體(ti)的電(dian)離。(2) 粉(fen)塵的荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)塵的捕集。
