Description
Technical Field
The utility model relates to a box type parallel flow electrolysis or electrodeposition device.
Background
The electrolysis and electrodeposition process of nonferrous metals is based on electrochemical principle, and the cathode and the anode are placed in a tank, and after the tank is electrified, electrochemical reaction is produced on the electrodes, and metal ions are continuously crystallized and separated out on the cathode. The electrode potentials of the various metal ions in the solution determine the order of their reactions at the cathode and anode, and metal ions with high electrode potentials preferentially precipitate at the cathode. The electrode potential is mainly determined by the standard electrode potential of the metal, the concentration of the oxidation state substance and the concentration of the reduction state substance in the electrochemical reaction. In the metal electrolysis and electrodeposition process, the standard electrode potential of metal is a fixed value, and the reduced substance is a metal simple substance (the activity is regarded as 1), so the concentration of metal ions in the solution has a great influence on the electrode potential. In production practice, when the current density is increased, the rate of precipitation of metal ions on the cathode is increased, resulting in a decrease in the concentration of metal ions near the cathode, but there is a limit in the rate of dissolution of metal ions from the anode or the rate of diffusion of metal ions from the electrolyte, and thus concentration polarization occurs. Concentration polarization causes the electrode potential of metal ions to decrease and the metal ions cannot be preferentially deposited on the cathode, and the possibility of other metals (impurities) being deposited on the cathode increases, affecting the quality of the final product. Therefore, the occurrence of concentration polarization during metal electrolysis and electrodeposition is a major cause of limitation in the increase of current density during electrolysis and electrodeposition.
In the traditional electrolysis and electrodeposition process, a solution enters a liquid from one end of a groove and goes out of the liquid from the other end of the groove, and the circulation mode is upward-in downward-out or downward-in upward-out. Therefore, the ion concentration near the cathode plate can not be ensured to be always in a higher concentration, when the current density is improved and the cathode ion precipitation is accelerated, concentration polarization is caused, the product quality is influenced, and the improvement of the current density and the product yield are limited.
In the process of electrolysis and electrodeposition in a parallel flow liquid inlet mode, the solution is fed from a liquid inlet device on the side surface of the tank, and the electrolytic cell is mainly characterized in that the flow direction of the solution is parallel to the cathode plate and the anode plate, the circulation volume is large, the flow is fast, and the concentration polarization is reduced. However, the higher liquid inlet speed and the higher circulation flow rate can cause the solution flow in the area between the polar plates to be disordered, which is not beneficial to the uniform distribution of ions between the polar plates on one hand and influences the sedimentation of the anode mud on the other hand. Meanwhile, as the solution enters from the side surface of the tank, part of the solution is easy to directly flow away from a channel between the edge of the polar plate and the side surface of the electrolytic tank and does not enter between the cathode plate and the anode plate. This will result in insufficient ion concentration between the anode and cathode plates, limiting further elimination of concentration polarization.
