ELECTROCHEMICAL REACTOR FOR PROCESSES FOR NON-FERROUS METAL ELECTRODEPOSITION, WHICH COMPRISES A SET OF APPARATUSES FOR GENTLY AGITATING AN ELECTROLYTE, A SET OF APPARATUSES FOR CONTAINING AND COALESCING AN ACID MIST, AND A SET OF APPARATUSES FOR CAPTURING AND DILUTING ACID MIST AEROSOLS REMAINING IN THE GAS EFFLUENT OF THE REACTOR

摘要

The invention relates to an electrochemical reactor for continuous copper electrodeposition at high current densities with copper sulfate electrolytes, which comprises devices and systems of functional means that are linked and operated in line, thereby forming a "triad", for standardising operational conditions in a series of operative parallel reactors. The triad, installed in each existing or new electrolytic container, comprises: a gentle electrolyte agitation system (AGSEL) with means for pulsing control of the aeration volume diffused by bubbling directed into each inter-cathodic space; a "duo" of systems linked in line, which comprises a system of removable anode covers (CAR) for containing, confining and coalescing the acid mist; and an acid mist recycling system (SIRENA) that captures non-coalesced electrolyte aerosols and condenses the steam, returning same to the process, while the pollutants of the gaseous fluid from the reactor are substantially diluted.
