Description
Technical field
The present invention relates to a kind of ground phosphate rock binding agent.
Technical background
Rock Phosphate (72Min BPL) is from exploitation, transport, to factory through processing treatment fed to boiler such as fragmentation, oven dry, screenings, lump ore amount only has about 50%, buy the qualified lump ore phosphorus through cleaning, usually also 15% ~ 20% to be lost, the ground phosphate rock enormous amount that the screening of phosphorus production enterprise is remaining, is not used and will causes the significant wastage of phosphor resource and serious financial loss." Yellow Phosphorus Industry entry criteria " that country implements explicitly calls for the breeze utilization ratio of yellow phosphorus enterprise to reach 100%.The technique that part phosphorus production enterprise attempts adopting ground phosphate rock to add clay or water glass dries as pelletizing after binding agent, in the hope of reaching the valuable phosphate rock resource of comprehensive utilization, reducing the object of product cost, but after adding clay or water glass, all reduces P in phosphorus ore
2o
5content, add the silicone content in ground phosphate rock, be not suitable for high silicon ground phosphate rock use.CN102381690 discloses medicament that a kind of rare earth element, sodium-chlor, calcium chloride, zinc chloride, sodium carbonate and salt of wormwood makes and montmorillonite powder in proportion, the powdered rock phosphate oxygen-enriched binder made after mixing, slaking, drying, ball grinds, but have that to add raw material numerous, making processes is tediously long and loaded down with trivial details, is difficult to the defects such as control and additional subsequent process after pyroreaction to the chemical composition in finished product and waste.
Summary of the invention
The object of this invention is to provide a kind of binding agent utilizing the intermediate product in two water thing method Wet-process Phosphoric Acid Production to make, not only can improve P in phosphorus ore pelletizing
2o
5content, and do not increase the silico-calcium ratio (acidity quotient Mk) in phosphorus ore pelletizing, be applicable to most ground phosphate rock and use.This binding agent effectively overcomes the defect that prior art exists, and proposes the new technical scheme of a kind of efficient circulation and utilize resources synthetically.
The present invention is achieved through the following technical solutions:
Concentrated for warp in the two water thing method Wet-process Phosphoric Acid Production solid content produced is 10% ~ 20%, P by a kind of ground phosphate rock binding agent
2o
5percentage composition be 40% ~ 47% acid sludge be stored in acid sludge groove, pump into liquid-solid phase reconditioner with acid sludge pump, making solid content is 30% ~ 50%, P
2o
5percentage composition be 30% ~ 35% ground phosphate rock binding agent.After this binding agent and ground phosphate rock are uniformly mixed in proportion, are dried by pressure ball molding or granulating roasting operation, produce phosphorus ore pelletizing.
Through the isolated Partial Liquid Phase product of liquid-solid phase reconditioner---phosphoric acid returns phosphoric acid production system and recycles.
The intermediate product that the present invention makes full use of Production Flow Chart in Production Flow Chart as auxiliary material direct reuse, is namely made with the middle acid sludge of two water thing method wet method phosphoric acid manufacture process and is produced ground phosphate rock pelletizing binding agent used, by P in ground phosphate rock pelletizing
2o
5content improve 8 ~ 10%., and do not increase the silico-calcium ratio (acidity quotient Mk) in phosphorus ore pelletizing.Achieve efficient circulation and the comprehensive utilization of phosphate rock resource.
Accompanying drawing explanation
Accompanying drawing 1 is production schematic diagram of the present invention.
