Reasons for fluctuations in EDI in ion membrane electrolyzers
Thread Content
Please offer some guidance from those who are more experienced
There are many reasons for fluctuations in potential difference. Regarding the pattern of these fluctuations, regular rhythmic variations can be caused by pressure differences, fluctuations in liquid flow rate, current fluctuations, or uneven current distribution due to poor welding at the electrolyzer frame. If the fluctuation pattern is one of steady increase followed by a steady decrease, it is necessary to check whether there is poor contact in the potential difference wires or if the sensors are malfunctioning
Fluctuations in tank temperature, unstable operating current, fluctuations in chlorine and hydrogen pressures, poor contact of connection wires, poor contact of the zeroing potentiometer, fluctuations in the flow rate of brine and alkali, unstable operation, etc
