Abstract
The utility model discloses a palmization liquid and lose liquid a little and retrieve copper device, including palmization liquid holding vessel, lose liquid holding vessel, broken twine groove and electrolysis trough a little, palmization liquid holding vessel with lose a little the liquid holding vessel all with broken twine groove intercommunication, broken twine groove with the electrolysis trough intercommunication, the positive pole and the negative pole in broken twine groove adopt titanium piece and nonrust steel sheet respectively. The difficult electrolytic problem of palmization liquid had both been solved to this recovery copper device, can effectively draw the copper that loses liquid a little again.
Description
Technical field
The utility model belongs to wiring board liquid waste disposal technique field, is specifically related to a kind of brown liquid and micro-etching solution reclaims copper device.
Background technology
The contained waste liquids such as a large amount of brown liquid, micro-etching solution are produced in PCB industry production process, in the process of electrolytic process process brown oxide waste liquid, because brown oxide waste liquid has certain brown film forming ability, easily form a skim at electrode surface during electrolysis, increase resistance, increase energy consumption and hinder copper to deposit at cathode surface.
Current microetch liquid medicine system is divided into persulphate series and sulfuric acid, hydrogen peroxide and stablizer series, and the former is used for heavy copper and two bronze medals, and the two is used for internal layer pre-treatment, OSP, thinning copper cash.Current, the process for micro-etched waste liquid mainly contains two kinds of modes, and one is directly sold cheap to recovery manufacturer; Another enters waste water disposal facility voluntarily to process.Due in micro-etching solution containing copper ion concentration about 15000-20000mg/L, therefore sell cheap to recovery manufacturer will cause no small financial loss to wiring board manufacturers.And waste liquid can give the unfavorable situation that wiring board manufacturers brings processing cost high by oneself.This unfavorable situation is caused mainly to be, the means of current wiring board manufacturers many employings dosing reduce the content of copper ion in waste discharge, this mode adding a large amount of chemical agent, except running cost is higher, separately has a large amount of copper mud to produce and waste discharge conductance too high (solvability salt causes) cannot reclaim the contingency question etc. of use.
Utility model content
For solving prior art Problems existing, the utility model proposes a kind of brown liquid with micro-etching solution reclaims copper device, this recovery copper device had both solved the problem of brown liquid difficulty electrolysis, effectively can extract again the copper of micro-etching solution.
The technical solution of the utility model is achieved in that
A kind of brown liquid and micro-etching solution reclaim copper device, comprise brown liquid hold-up vessel, micro-etching solution hold-up vessel, contact break groove and electrolyzer, described brown liquid hold-up vessel is all communicated with described contact break groove with described micro-etching solution hold-up vessel, described contact break groove is communicated with described electrolyzer, and anode and the negative electrode of described contact break groove adopt titanium sheet and stainless steel substrates respectively.
Further, also comprise strainer, described brown liquid hold-up vessel is all communicated with described strainer with described micro-etching solution hold-up vessel, and described strainer is communicated with described contact break groove.
Further, waste collection tank is provided with between described contact break groove and described electrolyzer.
Further, water pump is provided with between described brown liquid hold-up vessel and described strainer, between described micro-etching solution hold-up vessel and described strainer, between described strainer and described contact break groove, between described contact break groove and described waste collection tank and between described waste collection tank and described electrolyzer.
The beneficial effects of the utility model:
1, the micro-etching solution of the brown liquid in brown liquid hold-up vessel and micro-etching solution hold-up vessel is all added in contact break groove can reducing organic concentration in waste liquid, effectively can reduce COD in waste water so that follow-up electrolytic copper foil by adding contact break additive in contact break groove; Further, contact break groove Anodic adopts titanium sheet, negative electrode to adopt stainless steel substrates, can COD more effectively in degrading waste water.Make to produce at anode the free group that a large amount of similar hydroxyl radical free radicals etc. have high oxidative capacity by adding contact break additive, the free group of high oxidative capacity destroys the film forming ability of brown liquid, make the macromolecule organic of a large amount of stable existence dissociate out, the positively charged preferential cupric ion of organism of part obtains electronics at negative electrode and separates out.Through the reacted waste water pump of contact break to waste collection storage tank, then the waste drains pump in waste collection storage tank to electrolyzer will be carried out carrying Copper treatment.
2, brown liquid and micro-etching solution are through filter process before entering contact break groove, effectively can remove the suspended substance in waste liquid, facilitate follow-up contact break groove and electrolyzer process.
