Abstract
A kind of retrieving arrangement of use for laboratory precious metal indium, major parts comprises one-level retrieving arrangement and secondary recovery device, and every grade of retrieving arrangement is comprised of the mouth of pipe of bleeding, inlet pipe, accumulator tank, alkali lye adding trough, pH value detector, filtration unit, V-type funnel, waste liquid outlet valve.The cupric ion in photoelectric material CIS waste liquid is removed in electrolysis, waste liquid is discharged to the one-level retrieving arrangement of indium metal, in waste liquid, add diluted sodium hydroxide solution, every grade of retrieving arrangement has pH value time meter, and the pH value of test waste liquid is determined the amount of adding dilute sodium hydroxide according to pH value in time meter, fully after reaction, filtering-depositing, opens waste liquid outlet valve, by waste liquid discharged to secondary recovery device or discharge.For the indium in abundant Recycling of waste liquid, the pH value scope control of one-level retrieving arrangement is 4.0～4.5, and the pH value scope control of secondary recovery device is 4.5～4.8.Retrieving arrangement is simple in structure, and the effective and reasonable energy that utilizes, has very strong practicality and the value of environmental protection.
Description
Technical field
The utility model relates to a kind of retrieving arrangement of use for laboratory precious metal indium, relate in particular to recovery and the field of waste water treatment of precious metal.
Background technology
CIS solar cell is that research is the most extensive at present, realizes the compound film solar cell that industrialization is produced.Electro-deposition method is one of method of preparing CIS solar energy film of commonly using, after deposit film there is variation in various ionic concns, can not continue to utilize, but plating solution intermediate ion concentration is still very high, directly discharge, the one, indium has severe toxicity environment is worked the mischief, and the 2nd, indium is more valuable, causes waste.In the plating solution of deposition CIS, positively charged ion mainly contains cupric ion, sodium ion and indium ion.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, a kind of retrieving arrangement of use for laboratory precious metal indium is provided, reclaim precious metal indium, process the cupric ion in electroplating wastewater, and realize the recycle of material, environmental protection, apparatus structure is simple, has very strong practicality and the value of environmental protection.
The technical scheme that the utility model adopts is: major parts comprises one-level retrieving arrangement and secondary recovery device, and every grade of retrieving arrangement is comprised of the mouth of pipe of bleeding, inlet pipe, accumulator tank, alkali lye adding trough, pH value detector, filtration unit, V-type funnel, waste liquid outlet valve.The cupric ion in photoelectric material CIS waste liquid is removed in electrolysis, waste liquid is discharged to the one-level retrieving arrangement of indium metal, in waste liquid, add diluted sodium hydroxide solution, every grade of retrieving arrangement has pH value time meter, the pH value of test waste liquid, according to pH value in time meter, determine the amount of adding dilute sodium hydroxide, inlet pipe is connected gas device, to adding, in the waste liquid of alkali lye, pass into gas and play stirring action, after fully reacting Deng waste liquid and alkali lye, open filtration unit, the mouth of pipe of bleeding is connected motor and is started to filter waste liquid, after filtration finishes, open waste liquid outlet valve, by waste liquid discharged to secondary recovery device, equally, after secondary recovery device fully reacts and filters, waste liquid after processing is discharged.For the indium in abundant Recycling of waste liquid, the pH value that starts precipitation according to indium is 3.06 ~ 4.05, and in 4.67 ~ 4.85 precipitations of pH value completely, the pH value scope control of one-level retrieving arrangement is 4.0～4.5, and the pH value scope control of secondary recovery device is 4.5～4.8.
The beneficial effects of the utility model are: the middle precious metal indium that fully reclaims and dispose waste liquid, effectively remove the cupric ion in waste plating solution, and environmentally friendly, effective and reasonable Resource Recycling Utilization, apparatus structure is simple, and materials sodium hydroxide wide material sources are cheap, have very strong usability and the feature of environmental protection.
accompanying drawing explanation:
Fig. 1 is the structural representation of the utility model embodiment.
In Fig. 1,1 is the mouth of pipe of bleeding, and 2 is inlet pipe, and 3 is one-level retrieving arrangement, and 4 is accumulator tank, and 5 is alkali lye adding trough, and 6 is pH value detector, and 7 is filtration unit, and 8 is V-type funnel, and 9 is waste liquid outlet valve, and 10 is secondary recovery device.
embodiment:
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, also by reference to the accompanying drawings this programme is set forth.
In Fig. 1, electrolysis is removed the waste liquid of cupric ion in waste plating solution discharged to the accumulator tank 4 of one-level retrieving arrangement 3, by the pH value of pH value detector 6 test plating solutions, according to this value, determine the amount of the dilute sodium hydroxide that alkali lye adding trough 5 is added, connect the waste liquid that inlet pipe 2 passes into the gas stirring interpolation alkali lye of appropriate flow, fully reaction, again according to the pH value of pH value detector 6 test plating solutions, according to this value, determine the amount of the dilute sodium hydroxide that alkali lye adding trough 5 is added, make the pH value scope control of one-level retrieving arrangement 4.0～4.5, indium ion is opened 1 motor and the filtration unit 7 of bleeding mouth of pipe connection and is started to filter after fully precipitating, after filtering, open waste liquid outlet valve 9, by the waste liquid after filtering discharged to secondary recovery device 10, reaction is again filtered, the pH value scope control of secondary recovery device 10 is 4.5～4.8, after filtration, waste liquid is discharged.
