<p><P>PROBLEM TO BE SOLVED: To provide an electrolyte purifying system for copper electrolytic refining which can efficiently perform scale removal work in a short time in the electrolyte purifying system for copper electrolytic refining using the electrolyte of copper electrolytic refining. <P>SOLUTION: The electrolyte purifying system for copper electrolytic refining includes a circulating pump 2 for discharging a copper electrolyte, a heating still 3 for heating the copper electrolyte discharged from the circulating pump 2, an evaporator 4 for evaporating water in the copper electrolyte to generate a concentrate of the copper electrolyte, first piping 11 for connecting the circulating pump 2 to the heating still 3, second piping 12 for connecting the heating still 3 to the evaporator 4, third piping 13 for connecting the evaporator 4 to the circulating pump 2, and fourth piping 14 connected to the evaporator 4 to discharge the concentrate of the copper electrolyte from the evaporator 4. An adhesion inhibiting member for inhibiting scale adhesion is disposed on the inside walls of the first, second, third, and fourth piping 11, 12, 13, 14, and is not disposed in the heating still 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
