离子膜法烧碱电解槽的运行管理

摘要

介绍更换离子膜的注意事项,分析盐水中杂质对离子膜的影响.通过对盐水质量、进树脂塔盐水温度、氯酸盐含量、电解槽加酸、电解槽压差和开停车操作的管理和控制,延长离子膜的使用寿命,降低了生产成本,提高了企业的市场竞争力.%The matters needing attention in the replacement of ionic exchange membrane and the effect of impurities in brine on the membrane are introduced.Through the management and control of brine quality, temperature of brine fed to chelating resin tower, chlorate content, addition of acid to electrolyzers,electrolyzer pressure difference and start-up and shut-down operation, the service life of ionic exchange membrane is prolonged,the production cost is reduced,and the market competitiveness of enterprises is improved.
