Abstract
An excellent settling agent used for processing the concentration of wet-method phosphoric acid is prepared by sending 40-93 parts by mass of an anionic flocculating agent, 1-30 parts by mass of a non-ionic flocculating agent, 1-40 parts by mass of an adsorbent and 0-20 parts by mass of a fluorine removal agent to a stirring tank, controlling the temperature of the stirring tank in a range of 60-80DEG C through heating and heat insulation via a jacket, and allowing the solution obtained after stirring ending to stand for 10-40min. The excellent settling agent has the advantages of low prices and easy purchasing of the above used raw materials, simple preparation, less consumption, obvious shortening of the settling time of the concentration of wet-method phosphoric acid, effective reduction of the fluorine content, reduction of the contents of cations comprising Al<3+>, Fe<3+>, Ca<2+>, Mg<2+>, Si<4+> and the like, and realization of the clear texture and low impurity content of the produced concentrated wet-method phosphoric acid, and provides a high-quality raw material for subsequent production.
Description
Technical field
The present invention relates to a kind of sedimentation removal of impurities production technical field of concentrated wet-process phosphoric acid, be specifically related to the good sinking agent in a kind of phosphoric acid by wet process concentration process.
Background technology
After the phosphoric acid by wet process that makes by the sulfuric acid to leach phosphorus ore concentrates at present, make finished product through natural subsidence in subsider.Because the phosphoric acid by wet process viscosity after concentrating is bigger, shearing stress suffered in the natural subsidence process is bigger, has increased the frictional force of fluid inside, has hindered the subsidence rate of phosphoric acid, has reduced production efficiency, has improved production cost.
The use of phosphoric acid by wet process sinking agent can obviously be shortened the settling time and improve settling efficiency, reduces storage tank quantity, conserve space, reduce production costs, simplified the production management program, the phosphoric acid by wet process turbidity that makes is descended, become limpid, wherein part metals foreign ion Fe
3+, Al
3+, Ca
2+, Mg
2+, Si
4+Deng can catch by the net of sinking agent, build bridge, roll up sweep, effect such as charge neutrality removes along with reunion, the sedimentation of flco is able to part, the quality that has improved phosphoric acid by wet process has reduced the loaded down with trivial details property of subsequent handling and the use of medicament, also reduced the refining difficulty of phosphoric acid, reduced the discharging of tailings, be conducive to improve subsequent product quality, reduce production costs.
The flocculation agent kind of development research both at home and abroad roughly can be divided three classes at present: inorganic flocculating agent, organic polymer coargulator and biological flocculant.Wherein inorganic flocculating agent is generally inorganic salt and the inorganic polymer salt of Fe and Al; Organic polymer coargulator comprises two kinds of natural organic high-molecular flocculant and synthetic organic polymer coargulators; Biological flocculant generally is to utilize biotechnology to extract from the meta-bolites of microorganism and secretory product, because the costliness of the immature and cost of technology does not have large-scale promotion application at present.
At the foreign ion in the phosphoric acid by wet process with positively charged ion such as Al
3+, Fe
3+, Ca
2+, Mg
2+, Si
4+Etc. in the majority, avoid secondary pollution and bring new foreign ion into, should select the flocculation agent of anionic or non-ionic type for use.Therefore, inorganic flocculating agent such as bodied ferric sulfate (PFS) and polymerize aluminum chloride (PAC) are not done naturally and are considered, and biological flocculant is owing to hysteresis and the more high factor of Financial cost of technological development also will not adopt then.
The present situation of phosphorous chemical industry production at present, the phosphorus ore grade is not high relatively, and the concentration of the concentrated wet-process phosphoric acid of producing is 46 ~ 48%P
2O
5About, viscosity is bigger, the content of solid content and foreign ion is higher, longer by the time that natural subsidence needs, need the quantity of storage tank more, the space that occupies is bigger, production efficiency is low, the concentrated wet-process phosphoric acid that production obtains of low quality increased the difficulty that subsequent technique is handled, and influenced the quality of derived product.
Summary of the invention
Concrete grammar of the present invention is as follows:
Good sinking agent in a kind of phosphoric acid by wet process concentration process is by anionic flocculant, flocculant in non-ion type, sorbent material and form except fluorine reagent four parts, with anionic flocculant, flocculant in non-ion type, sorbent material and except fluorine reagent be 40 ~ 93 parts with mass fraction respectively, 1 ~ 30 part, 1 ~ 40 part, send in the oar formula steel basin for 0 ~ 20 part, steel basin is by the chuck heat tracing, temperature control is between 60 ~ 80 ℃, stirring rake stirs 5 ~ 15min fast with the stir speed (S.S.) of 200 ~ 500r/min, stir speed (S.S.) with 50 ~ 80r/min stirs 10 ~ 30min at a slow speed again, stirring finishes solution left standstill 10 ~ 40min, makes this sinking agent.
Above-mentioned anionic flocculant is one or more in sodium laurylsulfonate, sodium polyacrylate, polyacrylic acid, alkyl benzene sulphonate (ABS), the sodium alkyl benzene sulfonate.
Above-mentioned flocculant in non-ion type is one or more in non-ionic polyacrylamide, polyoxyethylene, polyvinyl alcohol, the Natvosol.
Above-mentioned sorbent material is one or more in diatomite, wilkinite, gac, the molecular sieve.
Above-mentioned except fluorine reagent be in sodium-chlor, sodium hydroxide, calcium oxide, calcium hydroxide, yellow soda ash, potassium hydroxide, the salt of wormwood one or more.
Advantage of the present invention: the employed raw material of good sinking agent is more cheap relatively, and raw material is buied easily, prepares easyly, and consumption is few, can obviously shorten the settling time of concentrated wet-process phosphoric acid, reduces fluorine content effectively, reduces Al simultaneously
3+, Fe
3+, Ca
2+, Mg
2+, Si
4+Etc. cationic content, make the concentrated wet-process phosphoric acid quality produce limpid bright, foreign matter content is low to provide high-quality raw materials for follow-up production.
