[0002] The electrolytic cell is a commonly used electrochemical device used for electrolysis of metals, separation of chemicals, etc. In the electrolytic cell, the current passes through the cell solution and is accepted by the cations or anions in the electrolyte, and a reduction or oxidation reaction occurs at the cathode or anode, thereby realizing an electrochemical reaction. The electrolytic cell is a commonly used purification equipment for copper refining in the copper smelting industry.

[0003] Existing electrolytic cells such as CN212713777U panel and parallel flow electrolytic cells using the same usually adopt a single-side single-channel liquid supply mode, that is, only one side of the electrolytic cell is provided with a set of liquid supply channel system. In actual operation, the circulating electrolyte flows into the electrolytic cell from the upper, middle or lower side of the electrolytic cell, and the ion concentration at the electrolyte replenishment inlet is relatively high, which leads to different degrees of deviation in the electrode deposition efficiency at various locations on the electrode plate a. In addition, due to the single-side single-channel liquid supply mode, in order to ensure the electrolysis efficiency, the liquid inlet flow rate cannot be too slow, and the relatively fast electrolyte flow rate increases the liquid surge in the electrolytic cell, thereby hindering the sedimentation of impurities electrolyzed, and the suspended impurities may be attached with the cathode electrodeposition, thereby affecting the product purity.
