AI Technical Summary
The fixed electrode spacing design of existing electrolytic cells results in high energy loss, poor process adaptability, and a reduced service life due to electrode coating wear or diaphragm deformation.
An adjustable electrode assembly is used, in which the adjustable electrodes of the anode and cathode assemblies move along the electrode rod to adjust the distance between the anode and cathode, and combined with a DC power supply, the reaction conditions are dynamically optimized.
This achieves a balance between power consumption and electrolysis efficiency, extends the service life of the electrolytic cell, and reduces maintenance costs.
