Applications of new technologies for zero-gap electrolyzers in reformation of electrolyzers

介绍了蓝星(北京)化工机械有限公司推出的膜极距电解槽新技术。该技术在电解槽改造中的应用包括:改进电解槽气液分离结构,改进电解槽循环结构,改进电解槽底网参数,优化电解槽弹性网的设计,改进槽阴极面网。给出该技术在不同槽上改造后的实际运行数据。从改造完的电解槽运行数据看,应用效果显著。电解槽气液分离结构的改进,使得上部气体和液体分布得更加均匀,减少了气体滞留量,延长了离子膜的使用寿命。电解槽内部循环结构的改变,使液体循环得更加充分,浓度和温度分布更加均匀。阴极网工艺参数的改进,使之更加适合在较高电流密度下运行,且耐腐蚀性更强,运行数据更加稳定。电解涂层技术的改进,不仅使电解槽电压越来越稳定,也使电解槽抗反向电流的能力进一步加强。

Tlie new technologies for zero-gap electrolyzers developed by Bluestar ( Beijing) Chemical Machinery Co., Ltd. were introduced. The applications of these technologies in the improvement of electrolyzers were as follows: improving the gas-liquid separation structure of the electrolyzers, improving the circulation structure of the electrolyzers, improving the parameters of the bottom network of the electrolyzers, optimizing the design of the elastic network of the electrolyzers, modifying cathode surface network. The actual operation data of different electrolyzers transformed by the technologies were given, showing remarkable effect. The improvement of gas-liquid separation structure of electrolyzer made the upper gas and liquid distribute more evenly, which reduced gas retention and prolonged the service life of ionic membrane. The change in circulating structure of electrolyzers made the liquid circulate more fully and the distribution of concentration and temperature more unifonn. The improvement of cathode network process parameters made the electrolyzers more suitable for operation at higher current density and corrosion resistance stronger, and made operation data more stable. The improvement of electrolytic coating technology not only made the voltage of electrolytic cell more and more stable, but also further strengthened the ability of electrolytic cell to resist reverse current.
