Description
Technical field
The utility model relates to a kind of regeneration complete equipment of nitric acid strip waste liquid, belongs to plating offal treatment field.
Background technology
Electroplating industry not only can improve protection and the decorate properties of product, and provides a lot of novel material for industrial and agricultural production, is an important industrial trade.In electroplating industry, copper plating process uses wider a kind of technique.
In electroplating process, the hanger as plating piece supporter is also coated with corresponding various metal plating.Again because hanger is all Reusability usually, after a collection of workpiece has plated, directly enter down one electroplating work procedure. just coming into operation as cleaned hanger not in time, other work pond liquid can be polluted, affect quality product.The same with the strip of those defective workpiece, most factory utilizes the copper of nitric acid dissolve workpiece surface.A large amount of nitric acid strip waste liquid containing nitric acid and cupric nitrate can be produced like this, wherein containing the Cu that concentration is higher
2+, H
+, NO
3 -if directly discharged, not only waste resource, also can cause severe contamination to environment simultaneously.
The domestic and international recycling technology for electroplating copper cash nitric acid strip waste liquid mainly contains chemical precipitation method, ion exchange method, electrolytic process, evaporation concentration method, solvent extration and membrane separation process at present.But aforesaid method, except chemical precipitation method, all exists complicated operation, problem that cost is higher, the conventional chemical precipitator method, also owing to regulating pH, add several flocculation coagulant aidss and cost difficulty are controlled.
Utility model content
Technical problem to be solved in the utility model is exactly overcome the deficiency in current technology, provides a kind of regeneration complete equipment of nitric acid strip waste liquid, and the copper in Separation and Recovery nitric acid strip waste liquid, completes the regeneration of nitric acid deplating liquid.
The utility model is realized by following technical proposals.
The regeneration complete equipment of a kind of PCB factory electro-coppering wire holder nitric acid strip waste liquid, comprise waste collection groove, reactor, suction filtration tank, accurate filter, regenerated liquid storage tanks and pumping and vacuum pump group, it is characterized in that waste collection groove is by pumping and pipeline ligation still, reactor is connected suction filtration tank by pumping with pipeline, suction filtration tank is connected accurate filter by pumping with pipeline, the liquid outlet of accurate filter connects regenerated liquid storage tanks, and suction filtration tank also connects vacuum pump group.
The regeneration complete equipment of a kind of PCB factory electro-coppering wire holder nitric acid strip waste liquid, it is characterized in that the nitric acid strip discharging of waste liquid of electro-coppering wire holder to waste collection groove, be pumped in reactor, strip waste liquid and regenerative agent mix and blend in a kettle. by a certain percentage, generate the mantoquita being insoluble to nitric acid, take out a certain amount of waste water to suction filtration tank after reaction for some time in batches, open vacuum pump group, solid-liquid separation is completed by filter cloth, mantoquita waste residue is stayed on filter cloth, filtrate is pumped to accurate filter impurity screening bottom suction filtration tank, then collect regenerated liquid storage tanks for product line nitre folder cylinder, regular taking-up filter cloth, unloads filter residue, puts back to suction filtration tank and continue to use after cleaning.
The renovation process of a kind of nitric acid strip of the utility model waste liquid and suite of equipment, structure is simple, easy to operate, both reclaimed the copper in strip waste liquid, the regeneration of the nitric acid completed again, there is higher economic worth, substantially achieve zero release, achieve environmentally friendly resource utilization and reclaim object.Decoating liquid copper content after regeneration is very low, and acidity is restored, and has no effect to strip, and acidity deficiency adds 68% concentrated nitric acid according to processing requirement, adjusts the parameter required by this decoating liquid to technique, can again for producing the strip operation of line.

Embodiment
For describing constitutional features of the present utility model, technique means and the object realized and effect in detail, accompanying drawing is coordinated to be described in detail below in conjunction with embodiment.
As shown in Figure 1, a kind of regeneration complete equipment of nitric acid strip waste liquid, comprise waste collection groove 1, reactor 2, suction filtration tank 4, accurate filter 6, regenerated liquid storage tanks 7 and pumping 3 and vacuum pump group 5, it is characterized in that waste collection groove 1 is by pumping 3 and pipeline ligation still 2, reactor 2 is connected suction filtration tank 4 by pumping 3 with pipeline, the bottom of suction filtration tank 4 is connected accurate filter 6 by pumping 3 with pipeline, the liquid outlet of accurate filter 6 connects regenerated liquid storage tanks 7, and suction filtration tank 4 also connects vacuum pump group 5.Vacuum pump group 5 is connected on the sidewall of suction filtration tank 4, its liquid level higher than the filtrate of suction filtration tank 4 bottom below the filter cloth being positioned at suction filtration tank 4.
A regeneration complete equipment for nitric acid strip waste liquid, its regeneration treatment step is as follows:
The nitric acid strip waste liquid (main component is nitric acid and cupric nitrate) produced when plating copper cash nitre folder strip cylinder is changed cylinder is discharged into waste collection groove 1, strip waste liquid and regeneration liquid medicine mix and blend in reactor 3 in proportion,
Generate the mantoquita being insoluble to nitric acid, react and be extracted into suction filtration tank 4 after 30 minutes in batches, open attached vacuum pump group 5, under condition of negative pressure, spent acid solution is accelerated through filter cake and filter cloth, flow to suction filtration tank 4 bottom, this copper is trapped within filter cloth, is pumped down to accurate filter 6 impurity screening when filtrate keeps in high liquid level bottom suction filtration tank 4, is back to plating line nitre folder cylinder after then keeping in regenerated liquid storage tanks 7; Regular taking-up filter cloth, unloads filter cake, puts back to suction filtration tank 4 and continue to use after cleaning.
For the nitric acid strip waste liquid that copper content is 57.18g/L, acidity 6.18mol/L, the mol ratio of cupric nitrate in regenerative agent and strip waste liquid is made to control 1: 1, the two mixes and reacts 30min, suction filtration get filtrate record regeneration after decoating liquid cupric 10.96 mg/L, acidity 7.65mol/L.Decoating liquid copper content after regeneration is very low, and acidity is restored, and has no effect to strip, and acidity deficiency adds 68% concentrated nitric acid according to processing requirement, adjusts the parameter required by this decoating liquid to technique, can again for producing the strip operation of line.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model.Every utilize the utility model and accompanying drawing content the conversion of structure, material and purposes done, be all in like manner included in scope of patent protection of the present utility model.
