針對現役燃煤電廠濕式靜電除塵器配件效率低下的原因，提出以下三種改造方案，分別為增加電場、改為袋式除塵器、改為靜電袋式復合除塵器。

　　增加(jia)電(dian)(dian)(dian)場在其它條(tiao)件不變(bian)的條(tiao)件下，增加(jia)在靜電(dian)(dian)(dian)除塵器收塵板面(mian)積可以提高除塵效率。要增加(jia)收塵板面(mian)積對原靜電(dian)(dian)(dian)除塵器進行擴容。

　　目前對已投(tou)運的(de)靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)要(yao)進行(xing)擴容(rong)有二(er)個方(fang)案(an)可供選(xuan)擇(ze)：(1)將(jiang)(jiang)原靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)加(jia)寬(kuan)(kuan)；(2)在原靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)基礎上(shang)增加(jia)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)。二(er)者相比(bi)，采(cai)(cai)取增加(jia)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)的(de)方(fang)案(an)效(xiao)(xiao)果(guo)要(yao)比(bi)采(cai)(cai)用(yong)將(jiang)(jiang)原靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)加(jia)寬(kuan)(kuan)的(de)方(fang)案(an)效(xiao)(xiao)果(guo)好。這是(shi)由于(yu)粉塵(chen)(chen)的(de)荷電(dian)(dian)(dian)(dian)特(te)性及被收集(ji)的(de)難易程度(du)決定的(de)，不同粒徑的(de)粉塵(chen)(chen)在不同的(de)電(dian)(dian)(dian)(dian)壓(ya)等級和電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)強度(du)下，才能保證其迅速而充(chong)分荷電(dian)(dian)(dian)(dian)及的(de)被收集(ji)。因(yin)此同一(yi)臺除(chu)塵(chen)(chen)器(qi)(qi)在收塵(chen)(chen)面積相同的(de)條件下，采(cai)(cai)用(yong)多而小的(de)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)要(yao)比(bi)采(cai)(cai)用(yong)少而大的(de)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)(chang)很(hen)有利于(yu)收塵(chen)(chen)效(xiao)(xiao)率的(de)提(ti)高。

　　在(zai)靜電(dian)(dian)除塵(chen)器電(dian)(dian)場較少、設計(ji)效(xiao)率(lv)較低的(de)情況(kuang)下(xia)，可(ke)以在(zai)原(yuan)有的(de)基礎上，增加一個或兩個電(dian)(dian)場使靜電(dian)(dian)除塵(chen)器達到四個甚(shen)至五個電(dian)(dian)場，靠(kao)增加靜電(dian)(dian)除塵(chen)器的(de)收塵(chen)面(mian)積、增加串聯的(de)電(dian)(dian)場數量(liang)來提高(gao)除塵(chen)器效(xiao)率(lv)，使靜電(dian)(dian)除塵(chen)器除塵(chen)效(xiao)率(lv)提高(gao)。
