Description
Technical field
The present invention relates to aluminium ore red-mud settlement technical fields, and in particular to a kind of preparation side of aluminium ore flocculating agent for red mud precipitation
Method.
Background technique
Aluminum oxide industry is the basic raw material industry of national economy, plays important work to the development of Chinese industrial economy
With the yield of China's aluminium oxide ranks first in the world.Alumina-producing method is all made of alkaline process at present, and red mud slurry is bauxite
The suspension of red mud and sodium aluminate solution composition after alkali soluble goes out.Slurries make red mud and aluminium by sedimentation or filtering after dilution
Acid sodium solution separates, and then produces aluminium oxide by sodium aluminate solution.The sedimentation separation of red mud is to influence aluminium oxide production capacity, product
One of matter and the key link of benefit.In order to strengthen the sedimentation separation of red mud, alumina producing factory and correlative study institute are done
A large amount of work.Purpose is to improve the sinking speed of red mud, the density of improvement subsider overflowing liquid quality and underflow, to mention
The production efficiency of high equipment and production cost is reduced, and adding flocculant is to generally use at present and effective method, is opened
The hot subject that hair novel flocculant technology is always studied both at home and abroad, state produce the raw material of aluminium oxide mainly with intractable one
Based on diaspore, there is very big difference with external boehmite and gibbsite.
In production technology, foreign countries use Bayer process, and China also uses intensified-sintered and mixed connection etc. in addition to Bayer process
Method.Red mud ingredient and foreign countries are widely different, so that polymer inlet flocculant is selective to domestic red-mud separation.In recent years
Nail (unit of length) section, cyanogen spy and the France for coming the U.S. like that the external major company such as gloomy is directed to China's bauxite feature and does a lot of work, and develop
Some novel flocculants, but external manufacturer holds its effective component and technology of preparing in close confidence, and expensive, because
This, exploitation has independent intellectual property right, is suitable for the new and effective flocculant of China's bauxite red mud sedimentation separation to China
The development of aluminum oxide industry is significant, and flocculant used in red-mud separation is mainly the polyacrylate of anionic at present
Or the hydrolysate of polyacrylamide, dosage form are mainly the hydrosol, dry powder and low concentration reversed-phase emulsion, water-soluble gluey or powdery
Flocculant hygroscopicity is strong, and effective active composition is caused to reduce, and causes additive amount big, and flocculating effect is unstable, and synthetic technology is single,
Low concentration reversed-phase emulsion haves the shortcomings that molecular weight is low, stability is poor again, and using effect is also undesirable.
Summary of the invention

Acid disodium and 0.25~1.0 part of di-isopropyl peroxydicarbonate are implanted sequentially in reaction kettle, continue that constant temperature is kept to continue to stir
It mixes, until stirring is completely dissolved, is configured to polymerized emulsion and continues to employ, by measure 110~150 parts of cycloalkane, 8~12 parts
Grease is sequentially added in agitator tank and is stirred, and is stirred evenly to internal solution, and oil liquid is obtained；
Oil liquid obtained in S2 is slowly injected into configuration in S2 and completed in the reaction kettle of polymerized emulsion, together by S3, mixing
When be stirred, then ortho phosphorous acid sodium solution obtained in S2 is injected into temperature in 25~70 DEG C of reaction kettle, to temperature
When stopping rising, keep the temperature of reaction kettle at 45~70 DEG C by constant temperature water box, after the reaction time for keeping 1.5~4h,
Temperature is improved to 80~95 DEG C, 5~50 parts of hydroxamic acid agent is slowly added in reaction kettle；
S4, discharging, will be anti-by constant temperature water box after reacting 3~7h by the reaction kettle that hydroxamic acid agent reaction is added in S3
It answers kettle internal temperature to be down to 40~55 DEG C, then 15~20 parts of nonionic surface active agent is slowly added in reaction kettle, together
When be stirred, aluminium ore flocculating agent for red mud precipitation lotion needed for being obtained after being mixed after 0.5~1h to be mixed.
Preferably, the hydroxamic acid agent is hydroxylamine hydrochloride.
Preferably, the nonionic surface active agent is sorbitan fatty acid ester, glyceryl stearate, fatty alcohol
One of aliphatic ester and polyoxyethylene fatty acid ester or a variety of mixing.
Preferably, the aluminium ore flocculating agent for red mud precipitation lotion, which is evaporated under reduced pressure, is made solid content up to 50~55% flocculants
Lotion finished product.
Compared with prior art, the beneficial effects of the present invention are: the present invention is mixed using monomer polymerization lotion and modified emulsion
Stirring is closed, mutually method is slowly dropped into salt water relative to traditional oil, saves a large amount of reaction time, improve production efficiency, and mixed
Dissolved after conjunction it is uniform, final products be free of organic solvent, while using β-monomethyl itaconate both effectively prevent polymerization Shi Yikang
Sour single chain transfer, and be conducive to aluminium ore red mud for the effective carboxyl functional group of long-chain introducing and tangle, play " frame
The effect of bridge " achievees the purpose that separation, improves the sinking speed of red mud, safer to environment and operator, hence it is evident that improves
The clarity of supernatant, reduces waste, and product sedimentation separation effect in the application of aluminium ore red mud improves particularly evident.
