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(chu)塵(chen)(chen)器(qi)是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收捕(bu)廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)和沉淀兩個系統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)調整后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)能(neng)較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫(heng)斷面擴大的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降低，其(qi)中有(you)些較重(zhong)的(de)(de)(de)塵(chen)(chen)粒(li)便失去速度(du)而(er)沉降下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)通(tong)(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)作用下(xia)趨向本(ben)設備陽(yang)(yang)極(ji)(正極(ji)、本(ben)設備采用負高(gao)壓(ya)制(zhi))和陰(yin)極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)(tong)過設備陰(yin)陽(yang)(yang)極(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使沉積在(zai)陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)落(luo)，進人(ren)(ren)集灰斗 通(tong)(tong)過排灰裝(zhuang)置(zhi)放(fang)出，回(hui)收有(you)物料，被(bei))凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工作(zuo)原理(li)是利用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)(xia)與氣流分離(li)。負極由不(bu)同斷面形(xing)狀(zhuang)的(de)(de)金屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何(he)形(xing)狀(zhuang)的(de)(de)金屬板制成(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)(chen)性質(zhi)、設備構(gou)造(zao)和(he)煙(yan)氣流速(su)等三個因素的(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有(you)直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重(zhong)返氣流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出(chu)，在塵(chen)(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產(chan)生局部擊穿(chuan)和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些(xie)情況(kuang)都會造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下(xia)(xia)降。

電(dian)(dian)除塵器(qi)的基本原理是利用電(dian)(dian)力捕集煙氣中(zhong)的粉塵，主要包(bao)括以下四個相互有(you)關的物理過程(cheng): (1) 氣體的電(dian)(dian)離。(2) 粉塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的捕集。
