Description

Technical Field

[0001] The utility model relates to the technical field of etching liquid regeneration and circulation, in particular to an acid etching liquid regeneration and circulation copper recovery device. Background Art

[0002] Etching liquid is a raw material for copperplate engraving. It is a liquid that is engraved by corroding the characteristics of the material. Theoretically, any reagent that can oxidize copper to form soluble copper salts can be used to etch copper-clad boards, but the damage to the anti-etching layer, etching speed, etching coefficient, copper dissolving capacity, solution regeneration and copper recovery, environmental protection and economic effects must be weighed.

[0003] Generally, acidic etching liquid is used to recover copper by electrolysis. During the electrolysis process, if there is a monovalent copper ion in the anode reaction zone, it will first lose electrons and oxidize into a divalent copper ion, and then undergo an oxidation reaction of chloride ions to generate chlorine gas. Generally, chlorine gas leakage is prone to occur in electrolytic equipment. Chlorine gas enters the body of workers through the air and is likely to cause damage to the human body. In the cathode reaction zone of the general electrolytic equipment, the divalent copper ions will obtain electrons and be reduced to copper element. The copper element adheres to the surface of the reaction rod, which is likely to reduce the reduction reaction rate, resulting in a decrease in the efficiency of copper recovery. In view of the above problems, an acidic etching liquid regeneration and circulation copper recovery equipment is proposed to solve them. Utility Model Content
