BiTAC电解槽膜极距技术改造

摘要

介绍中盐吉兰泰盐化集团有限公司对BiAC电解槽进行膜极距改造的过程.通过优化槽结构、选用合适的离子膜、更换法兰面、改变密封形式,单元槽电压下降到2.98 V以下,生产1 t 30%烧碱的交流电耗下降350 kW· h/t.%Jilantai Salt Shemical Group Co., Ltd., China National Salt Industry Co.made zero-gap remodeling on BiTAC electrolyzers.The remodeling process was introduced, including optimization of electrolyzer structure,selection of suitable ion exchange membrane,and change of flange surface and seal form.The cell voltage dropped to less than 2.98 V,and the AC consumption decreased by 350 kW· h/t for one ton of 30% caustic soda.
