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)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)中(zhong)的粉塵(chen)，它的凈化工(gong)作(zuo)上要是依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉淀(dian)兩個系統來(lai)完成的，當含(han)塵(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)分(fen)布(bu)板以(yi)及折流(liu)板的調整后，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的作(zuo)用下(xia)，氣(qi)(qi)流(liu)速度迅(xun)速降低，其(qi)中(zhong)有(you)(you)些(xie)較重的塵(chen)粒(li)便失(shi)去速度而沉降下(xia)來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的含(han)塵(chen)氣(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的電(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)，這些(xie)電(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的粉塵(chen)結合起(qi)來(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的作(zuo)用下(xia)趨(qu)向本(ben)設備(bei)(bei)陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備(bei)(bei)采用負高(gao)壓制(zhi))和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)(zi)(zi)分(fen)別沉積在(zai)相(xiang)應的電(dian)(dian)(dian)極(ji)(ji)上，通過設備(bei)(bei)陰(yin)陽極(ji)(ji)振(zhen)打系統的振(zhen)打，使(shi)沉積在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上的粉塵(chen)振(zhen)落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通過排灰(hui)裝置放(fang)出，回收有(you)(you)物(wu)料，被(bei))凈化的氣(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工作原(yuan)理(li)

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)工作(zuo)原理(li)是(shi)利用高壓(ya)電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離，氣流(liu)中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離。負(fu)極(ji)(ji)(ji)由不(bu)(bu)同斷面形(xing)(xing)狀的(de)(de)金(jin)屬導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)(bu)同幾何形(xing)(xing)狀的(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙氣流(liu)速等三個因素的(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是(shi)評價導電(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)難以(yi)保持在集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使其(qi)重返氣流(liu)。比(bi)電(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)(he)不(bu)(bu)易(yi)放(fang)出，在塵(chen)(chen)(chen)(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)壓(ya)梯度會產(chan)生局(ju)部擊穿和放(fang)電(dian)(dian)現(xian)象。這(zhe)些(xie)情況都會造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)(chen)效率(lv)下降。
