Abstract
The invention discloses oil removing method from nickel chloride solution through extracting method, which comprises the following steps: clarifying chloride solution to separate organics; demulsifying solution through ultrasound; aerating gas; floating; adsorbing oil through fiber filament; making the organics in the solution to 2-5ppm.
Description
Technical field
A kind of method of eliminating oil from nickel chloride solution relates to nonferrous metallurgy nickel and smelts in the hydrometallurgy deoiling method of solution behind the chloridizing leach solution abstraction impurity removal.
Background technology
Along with the development of electroplating industry, promoted of the application of nickelous chloride product at electroplating industry.Fields such as assorted accuracy electroplate, electroless plating are more and more higher to the specification of quality of nickelous chloride product.In order to improve the quality of nickelous chloride product, adopt various purification and impurity removal means in the production, reduce the product foreign matter content.Abstraction impurity removal is the method for a kind of deep impurity-removing common during nickelous chloride is produced.One side deep purifying nickel chloride solution is on the other hand by extraction means Separation and Recovery valuable metal.When the removal of impurities of extracting and purifying method offers convenience, also brought new impurity-organism into to product.Nickelous chloride product organism source mainly contains two aspects, and the one, oil-in-water band people behind the solution extraction, the 2nd, machinery is brought into.It is too high that the nickelous chloride product contains organism, can make the solution muddiness, not limpid, has bubble to produce, and influences solution conductivity in electroplating process, and plating piece and binding force of cladding material are not strong, influence coating surface quality.Adopt clarification to separate deoiling methods such as oil removing, charcoal absorption, malthoid absorption during general nickelous chloride is produced, deoiling effect is undesirable, regeneration difficulty, cost height.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively reduce through the organism in the nickel chloride solution after the extraction, makes it to adapt to the method for the eliminating oil from nickel chloride solution of accuracy electroplate needs.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of eliminating oil from nickel chloride solution, it is characterized in that at first with nickel chloride solution through inclined plate grease pond clarification separated free organism, with ultrasonic wave solution is carried out feeding gas solution behind the breakdown of emulsion again and carries out dissolved air flotation, through fiber yarn absorption oil removing, make the organic content in the solution reduce to 2～5ppm at last.
Method of the present invention, utilize the nickel chloride solution behind the abstraction impurity removal, through entering the organism of inclined plate grease pond clarification separated free after the press filtration, ultrasonic dehydration destroys the water soluble organic substance structure, organism is isolated in solution and high pressure gas mixing air supporting, again through fiber yarn and fibrous nodules absorption oil removing.Its deoiling effect is obvious, processing ease, and solution becomes limpider, transparent through after the oil removing, and organic content obviously reduces, and quality product is promoted, and has satisfied the needs of electroplating industry.
Embodiment
A kind of method of eliminating oil from nickel chloride solution, contain the organism of organic nickel chloride solution through inclined plate grease pond clarification separated free, make the organism of mechanical entrapment remove 80%, ultrasonic dehydration utilizes the ultrasonic wave wavelength to change, destroy the water soluble organic substance structure, isolate organism through solution and high pressure gas mixing air supporting again, solution through fiber yarn and fibrous nodules absorption oil removing, makes the organic content in the solution reduce to 2～5ppm again.
Embodiment 1
To contain the above nickel chloride solution of organism 50ppm, press following process operation:
A. inclined plate grease pond oil removing
Raffinate enters the preceding flow container of oil removing through after the press filtration, pumps into oil trap clarification separating floating, free organism with the volume pump dominant discharge.
B. ultrasonic dehydration, oil removal by air bubbling
Gravity flow enters ultrasonic dehydration, oil removal by air bubbling system through the solution after the oil trap oil removing, utilizes ultrasonic wave to produce microwave resonance, destroys the oil-in-water molecular structure, and solution and high-pressure blast enter dissolving dissolved air flotation organism, reach the purpose of oily water separation.
C. fiber yarn and fibrous nodules absorption oil removing
Solution behind ultrasonic dehydration, the oil removal by air bubbling is further removed the organism of carrying secretly in the solution through fiber yarn, fibrous nodules adsorption tower absorption oil removing.Organic content in the solution is reduced to 2～5ppm.Fiber yarn, fibrous nodules regular regeneration are to recover deoiling effect.
Claims (1)
1. the method for an eliminating oil from nickel chloride solution, it is characterized in that at first with nickel chloride solution through inclined plate grease pond clarification separated free organism, with ultrasonic wave solution is carried out feeding gas solution behind the breakdown of emulsion again and carries out dissolved air flotation, through fiber yarn absorption oil removing, make the organic content in the solution reduce to 2～5ppm at last.
