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(wo)式(shi)靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器是以(yi)靜(jing)(jing)電(dian)(dian)凈(jing)(jing)化(hua)法來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)要是依(yi)靠電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)和沉淀兩個系統來完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)(de)(de)(de)(de)調整后，使氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)。在橫斷面擴大(da)的(de)(de)(de)(de)(de)作用下(xia)(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降(jiang)低，其中有(you)些(xie)較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速(su)度而沉降(jiang)下(xia)(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直(zhi)流(liu)電(dian)(dian)，則在電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)暈現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存(cun)在大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)子和離(li)(li)子，這些(xie)電(dian)(dian)子和離(li)(li)子與進(jin)(jin)人(ren)(ren)電(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)粒(li)帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)作用下(xia)(xia)趨(qu)向本設備(bei)陽(yang)極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設備(bei)采用負高(gao)壓制)和陰極(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)子分別沉積在相(xiang)應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通過設備(bei)陰陽(yang)極(ji)(ji)(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)(de)(de)振(zhen)打(da)，使沉積在陰陽(yang)電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置放出，回收(shou)有(you)物料，被(bei))凈(jing)(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入大(da)氣(qi)(qi)。

工作原(yuan)理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作原(yuan)理(li)是(shi)利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣流(liu)分離。負極由(you)不(bu)同(tong)斷面形(xing)狀的(de)金屬導(dao)(dao)線(xian)制(zhi)成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾何(he)形(xing)狀的(de)金屬板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性能(neng)受粉(fen)塵(chen)(chen)(chen)性質、設備構(gou)造和煙(yan)氣流(liu)速等三個因(yin)素(su)的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標(biao)，它對除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)有直接(jie)的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)(chen)層(ceng)之間(jian)形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度(du)會(hui)產生局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)下(xia)降。

電(dian)除塵(chen)器的(de)基本原(yuan)理是利(li)用電(dian)力捕集煙氣中的(de)粉(fen)(fen)塵(chen)，主要包括以下四個相(xiang)互有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)向電(dian)極(ji)移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)的(de)捕集。
