（２）電(dian)解(jie)(jie)清洗在(zai)脫(tuo)脂(zhi)工(gong)藝中扮演重(zhong)要(yao)角色(se)，電(dian)解(jie)(jie)清洗效果(guo)直接影(ying)響(xiang)脫(tuo)脂(zhi)機組能否(fou)順(shun)行(xing)，但同時電(dian)解(jie)(jie)清洗脫(tuo)脂(zhi)也屬于高投(tou)資、高能耗、以及高危險環(huan)節，尤(you)其是電(dian)極板(ban)的腐蝕給現場生產維護帶來極大(da)麻煩［１１］。目(mu)前，電(dian)解(jie)(jie)清洗的常規配置為４５００／６０００／８０００Ａ，３６Ｖ，設(she)計(ji)功率在(zai)１５０ｋＷ以上，運行(xing)能耗很高。因此，亟待開(kai)發滿(man)足脫(tuo)脂(zhi)效果(guo)的新(xin)型低耗脫(tuo)脂(zhi)工(gong)藝。
