Description
[technical field]
The utility model relates to the regeneration of the etch combination that etch copper or copper alloy use, and refers to a kind of alkaline etching liquid cyclic regeneration electrolytic copper device especially.
[background technology]
Etching work procedure in the wiring board manufacturing process is one important procedure that wiring board is made,, the waste liquid that produces in this operation process is a kind of high-copper waste liquid [a cupric 110-160 grams per liter].To this etching waste liquor, current at present way is to have the recovery company of qualification to pull away waste liquid by the locality, and the copper that uses chemical process (neutralisation or substitution method) to reclaim in the waste liquid is then made copper sponge or copper sulfate.These method technologies fall behind, and copper reclaims not thorough, and the economic benefit of processing is not obvious, and the waste liquid of having carried behind the copper directly effluxes, and causes " secondary pollution ", and local water ecosystem is caused than havoc.
Exist a kind of extraction process that utilizes to make spent etching solution regeneration and copper-extracting process now, but this arts demand mix stirring with spent etching solution and extraction agent, thus the extraction agent of trace can be contained in the regenerated liquid, and some composition in the extraction agent and printing ink can react.So cause the regenerated liquid quality unstable.
[summary of the invention]
The utility model purpose is to provide a kind of simple in structure, the alkaline etching liquid cyclic regeneration electrolytic copper device that can avoid environmental pollution, can make the copper in the inefficacy etching solution be able to reclaim, and realizes economic benefit, avoids environmental pollution.
The beneficial effect of the utility model is: do not discharge the copper in waste liquid and the ability efficient recovery waste liquid.
The purpose of the utility model realizes through following technical scheme: electrolyzer is divided into cathode compartment and anolyte compartment, and described waste liquid carries out diaphragm electrolysis respectively in cathode compartment and anolyte compartment; Catholyte after the electrolysis gets into the catholyte equipment for separating liquid from solid; Carry out the solid-liquid filtering separation; Catholyte behind the separation copper gets into the catholyte storage tank; This catholyte is catholyte suction mixing regulating tank in the control lower section of specific gravity hydrometer or fluid level control device, all the other major parts can pumpback to cathode compartment, form closed cycle; Catholyte enters into the mixing regulating tank, with anolyte get into mix regulating tank and mix and regulate its pH value after, can pump into the etching bath production line and utilize again.
A kind of alkaline etching liquid cyclic regeneration electrolytic copper device; Comprise electrolyzer, the circulation groove that is connected with electrolyzer and RF; It is characterized in that: said electrolyzer is connected with circulation groove through electrolytic solution backflash and the electrolytic solution transfer lime that is arranged on the electrolyzer outer wall, and circulation groove is connected with recycle pump, and recycle pump is connected with the electrolytic solution transfer lime; The electrolytic solution transfer lime has some arms, and said arm is provided with valve.
Circulation groove is that electrolyzer provides rich copper bearing electrolytic solution, and RF is that electrolyzer provides electric current,
Said recycle pump will be rich in copper electrolyte and be evenly distributed in the electrolyzer through the electrolytic solution transfer lime, valve controlling flow amount size.
Be provided with positive plate and negative electrode copper-clad plate in the said electrolyzer, said positive plate is connected with negative electrode with the anode of RF respectively with the negative electrode copper-clad plate.Under galvanic action, the cupric ion in the electrolytic solution is reduced in the negative electrode copper-clad plate, constantly accumulates through copper in the copper-clad plate of reaction negative electrode, and cupric ion reduces in the electrolytic solution, gets back in the circulation groove through the electrolytic solution backflash.
Said circulation groove sidewall is provided with drain pipe.Waste gas is handled by waste gas absorption tower through collecting the back, avoids environmental pollution.
The beneficial effect of the utility model is: simple in structure, not only the inefficacy etching solution is obtained the utilization of resources, also avoided environmental pollution.
