The NaO concentration at the cathode side outlet of a single electrolyzer cell is too high – what should be done? ? ? The concentrations of the remaining units are all normal, except for one unit whose concentration is on the high side; please suggest a solution! ! ! (Are there any other ways besides adjusting the addition of water at 221?) ? ? )
Is it on the high side? What is the normal value? Under 0.5 should be fine.
How does the flow rate into the channel compare to that of the others? A slight increase under the same operating conditions is normal, as the performance of ion exchange membranes itself is not exactly identical
Just increase the cathode flow by a slight amount
What was said upstairs is correct – increase the alkali flow rate per tank cycle appropriately. It is also necessary to analyze why the value is high – whether it is due to the high water migration rate of the newly installed membrane or an inaccurate flow meter. In any case, this issue needs to be given attention as it can lead to problems.
The current in the single slot is too high; please check it.
Check the concentration of the brackish water leaving the tank to see if there is a significant difference.
In fact, when multiple electrolyzers operate as part of one system, due to factors such as operating current, efficiency, and circulation rate, the alkali concentration at the outlet of each electrolyzer is different! However, both theoretically and in practice, the deviation is not significant; even if multiple electrolyzers are shut down for cycling, the concentration of the product from the remaining few operating electrolyzers will not vary much, with only a slight decrease in the alkali concentration of the output! If the conditions of the original poster differ significantly, I suspect that the circulation rate of the cathode in this abnormal electrolyzer is too low!
