ELECTROLYTIC REGENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic regeneration device capable of being reduced in size and also decreased in bath volume.

SOLUTION: A regeneration unit 19 includes: a tubular portion 23 having an inner circumferential surface functioning as an anode; and a cathode 25 provided inside the tubular portion 23 and extending along the extending direction of the tubular portion 23 while being separated from the inner circumferential surface 31. A treatment liquid used for desmearing treatment is fed through a gap between the inner circumferential surface 31 of the tubular portion 23 and the cathode 25. A feed-side conduit 15 has a downstream-side end 15b connected to the tubular portion 23, and guides the treatment liquid discharged from a desmearing treatment tank 13 into the regeneration unit 19. A return-side conduit 17 has an upstream-side end 17a connected to the tubular portion 23 and guides the treatment liquid discharged from the regeneration unit 19 into the desmearing treatment tank 13.
