摘要
离子膜电解槽生命周期内需要进行半壳重涂和更换离子膜。根据半壳重涂和离子膜更换过程中的槽电压数据表现,以及超高电流密度下不同离子膜在不同型号电解槽上的电压数据进行分析,得出同等高电流密度下四、五、六代电解槽对应不同离子膜的经济运行方式,从而利用电解槽涂层改造期间择优选择更换不同系列离子膜,使得离子膜电解槽能在全生命周期内持续高效运行。
During the life cycle of ion-exchange membrane electrolyzers,anode recoating and ion-exchange membrane replacement are needed.According to the cell voltage data in the process of anode recoating and ion-exchange membrane replacement and according to the voltage data of different types of electrolyzers with different types of ion-exchange membrane operating under ultra-high current density,the economic operation modes for the fourth,fifth and sixth generation electrolyzers with different types of ion-exchange membrane operating under the same high current density are found.Thus,different types of ion-exchange membrane can be selected to replace the old membrane during the anode recoating.As a result,the ion-exchange membrane electrolyzers can operate continuously and efficiently in the whole life cycle.
