Description

Novel liquid inlet device of electrolytic cell

Technical Field

The utility model relates to the technical field of copper electrolytic refining, in particular to a novel liquid inlet device of an electrolytic cell.

In the copper electrolytic refining process, the electrolyte needs to be circulated ceaselessly, the purpose is to transfer mass and heat, supplement local ions caused by electrochemical reaction to be reduced or increased, keep the components and the temperature of the electrolyte at each part in the electrolytic cell uniform, reduce concentration polarization and be beneficial to the smooth operation of the electrolytic process.

The liquid inlet circulation mode of the copper electrolytic refining electrolyte is generally divided into an upper inlet and lower outlet mode and a lower inlet and upper outlet mode, the upper inlet and lower outlet mode of the conventional upper end inlet and lower end outlet mode is circulated, the electrolyte directly enters the upper portion of the electrolytic cell from one end of the cell and flows downwards from top to bottom, a liquid outlet partition plate is arranged at the other end of the electrolytic cell, and the electrolyte at the lower portion of the electrolytic cell is led out. And in addition, in a lower-inlet and upper-outlet circulation mode, the electrolyte enters the lower part of the electrolytic cell from one end of the electrolytic cell, flows from bottom to top in the electrolytic cell and overflows from an overflow box at the upper part of the other end of the electrolytic cell. The lower inlet and the upper outlet adopt a circulation mode of liquid inlet at the center of the bottom of the electrolytic bath and liquid outlet at two ends of the bath, and a liquid inlet pipe (PVC hard pipe) is arranged at the center of the bottom of the electrolytic bath along the length direction of the bath and is supplied through small holes (the hole distance is the same as the polar distance of the same name) uniformly distributed along the pipe.

The circulation mode of the upper inlet and the lower outlet and the circulation mode of the lower inlet and the lower outlet are 'one-end liquid inlet', and the natural convection controls the flow pattern on the vertical polar plate, so that the circulation of the electrolyte between the electrodes is insufficient. In this case, the electrolyte flows upward on the cathode surface and downward on the anode surface. Therefore, copper ions cannot be rapidly supplied from the boundary layer to the cathode surface. Conventional "one-end-feed" cells typically operate at low current densities of 220-280A/m 2. The lower inlet and the upper outlet adopt a circulation mode of feeding liquid at the center of the bottom of the tank and discharging liquid at the two ends of the tank, the liquid is fed through a bottom pipe, and the electrolyte components and the temperature are uniformly and uniformly distributed in each area in the tank. However, the liquid outlet holes of the liquid supply mode of the bottom pipe are multiple, the liquid overflows from the two ends of the electrolytic cell upwards from the bottom of the electrolytic cell, anode mud is easily stirred, and the settlement of the anode mud is not facilitated, so that a novel liquid inlet device of the electrolytic cell is urgently needed to solve the existing problems.
