This question is too broad; you can first search for keywords on the forum to learn more*. http://www.google.cn/search?q=%B5%E7%BD%E2%B2%DB%D4%CB%D0%D0&sa=%CB%D1%CB%F7&prog=aff&client=pub-0712079178777972&channel=9470486527&domains=bbs.hcbbs.com&hl=zh-CN&source=sdo_sb&sdo_rt=ChBJmMJXAApMNgp7BBfE8xoSEg5fX1JMX0RFRkFVTFRfXxoIhCPqEgFSvAQoAQ&sitesearch=bbs.hcbbs.com
I’m not sure which type of electrolyzer you’re referring to. Here are some points to keep in mind regarding ion-exchange membrane electrolyzers: 1. The quality of the saltwater – in particular, calcium and magnesium ions, as well as sulfate ions, have a significant impact on the electrolyzer; it’s important to monitor changes in their concentrations. 2. The concentration of sodium hydroxide in the catholyte. 3. The concentration of sodium chloride in the anolyte. 4. The pH value of the anolyte. 5. Temperature. It’s necessary to pay close attention to these factors and ensure that they remain within appropriate ranges; excessive fluctuations can affect the lifespan of the electrolyzer. Maintenance workers should conduct regular inspections of the electrolyzers. This is my understanding; please correct me if I’m wrong. This post was last edited by limingshuguang on 2009-2-17 09:32.]
In the later stages of operation of the electrolyzer, the performance of the ion membrane declines; attention should be paid primarily to the voltage of each cell and the purity of chlorine gas, with regular comprehensive analyses of the electrolyzer being conducted. Check for leaks in the cells of the electrolyzer, and address any leaks promptly. Also, since the cell feed pipe is a rubber-lined pipe, attention should be paid to fluctuations in the feed flow rate to prevent issues such as the rubber lining coming off or bubbling.
It is not specified whether it is the ion exchange membrane that reaches the end of its useful life or the electrode coating. If it is the ion exchange membrane, it is necessary to keep an eye on changes in cell voltage at all times, as well as to regularly analyze the hydrogen and oxygen content in chlorine
In the later stages of operation of the electrolyzer, close attention should be paid to the cell voltage, hydrogen and oxygen levels in chlorine, the purity of chlorine gas, as well as the salt content in the alkali within each cell. Analysis of chlorates is also essential. Regular inspections of the electrolyzers are necessary, and any leaks detected must be addressed promptly. Additionally, during start-up and shutdown processes, efforts should be made to minimize fluctuations in pressure difference.
You’re being too general; be more specific so it’s easier for people to answer
