Description
Technical field
The utility model relates to the processing technology field of spent etching solution, in particular, relates to a kind of alkaline copper etching regenerated liquid water washing device.
Background technology
Etching waste liquor is that PCB enterprise is when adopting subtractive process to produce circuitous pattern and the waste water that discharges.Etching waste liquor contains copper, chlorine, the ammonium ion of high density, belongs to Hazardous wastes, and directly discharging not only causes the waste of resource, and can produce serious environmental problem, and therefore, the exploitation etching solution recycles technology becomes in the industry focus.
Etching solution circulation and regeneration technology comparative maturity is solvent extraction-electrodeposition process at present, its technological process is: at first utilize the high selectivity of copper extractant to copper, most of to the extraction of the selective copper in the etching waste liquor, copper etching liquor after the raffinate adds the medicament adjustment and recovers to recycle behind the etching performance, the copper of extraction then obtains copper sulfate electrolyte by the sulfuric acid back extraction, the highly purified cathode copper of copper sulfate electrolyte output of last electrodeposition gained.Its technological principle is:
Extraction principal reaction: 2RH+Cu
2+=CuR
2+ 2H
+(RH represents extraction agent)
Back extraction principal reaction: CuR
2+ H
2SO
4=CuSO
4+ 2RH (RH represents extraction agent)
Electrode reaction:
Anode 4OH
-=O
2+ 2H
2O+4e
Negative electrode Cu
2++ 2e=Cu
Extraction and back extraction process include following three steps: profit mixing → clarification layering → oily water separation.
Because extraction and back extraction process all need oil phase and water thorough mixing, inevitably can carry the small amount of impurities ion secretly in the oil phase after the oily water separation.Owing to contain a large amount of ammonia nitrogens and chlorion in the etching waste liquor, solution is alkalescence, after the extraction agent extraction, load organic phases can contain the ammonia nitrogen and the chlorion of trace, operation year in year out, ammonia nitrogen that trace is carried secretly and chlorion will be brought in the electrolyzer along with the back extraction of oil phase, if do not take measures, ammonia nitrogen and chlorion long time integration in electrolytic solution can influence electrolytic efficiency, electrolytic copper quality product and increase the consumption of acid; And the later oil phase of back extraction can contain the sulfate radical of trace, operation year in year out, if the sulfate radical that carries is not got rid of, it will be transferred to along with oil phase in the etching solution, the continuous accumulation of sulfate radical, when its concentration reaches a certain amount of, can change the proportion of etching solution, when the content of sulfate radical is above above 35g/L, will influence etching speed.
Carry out ammoniacal liquor in addition at the etching work procedure back segment and wash operation; Along with the carrying out of etching process, content of copper ion can rise gradually and etching performance is descended in the etching solution, make etching solution reach optimum Working, must be with the Cl in the etching solution
-, Cu
2+, pH value adjusts in the optimum range, it takes constantly to add sub-liquid usually, overflow discharging mother liquor is that the mode of spent etching solution is adjusted, and makes above-mentioned various composition reach optimum concn, thereby recovers the etching solution performance.The etching solution of discharging just becomes spent etching solution, contains a large amount of copper and ammonia in the spent etching solution liquid, directly discharges not only serious environment pollution, and has wasted valuable metals resources.
China is to add reagent extraction copper wherein in order to produce copper sulfate to a kind of method of the utilization of PCB etching waste liquor, though its treatment process technology is simple, but need to consume a large amount of reagent, produce a large amount of washess, perhaps products obtained therefrom purity is not enough, and the etching reagent of can not directly regenerating, economic benefit is low.
Domestic adopt in addition ionic membrane technology directly under the etching solution alkaline system electrowinning copper carry out the method for cyclic regeneration, because the problem of technical thought problem and ionic membrane and negative plate, cause electrolytic solution chlorion and the mutual chemical reaction of other components, the etching solution component that causes regenerating is regulated difficulty, production stability is poor, two-sided and high-precision multi-ply wood can not use, there is hypertoxic gas chlorine to produce during electrolysis, in addition owing to adopt stainless steel plate in the electrolytic process as anode and cathode, cause electrolyte temperature too high, the most of powdering of the copper of output, purity is lower, simultaneously ammonia loss by volatilization is big, and the ammonia washing lotion can not cyclic regeneration; Electrolytic copper needs manual extraction one to twice every day in addition, causes the serious problem of loss of the big and ammonia of labour intensity.
