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, P in phosphorus ore pelletizing can be improved
2o
5content, also can enter the shaping use of stove to the ground phosphate rock of acidity quotient deviation comparatively large (Mk < 0.75 or Mk > 0.85).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 acidity regulator with acid sludge pump, add ground silica or the limestone powder of 1 ~ 10% of acid sludge gross weight, adjustment acid sludge acidity quotient, to Mk=0.5 ~ 1.0, makes ground phosphate rock binding agent.
After the ground phosphate rock of this binding agent and acidity quotient Mk < 0.75 or Mk > 0.85 is uniformly mixed in proportion, dried by pressure ball molding or granulating roasting operation, with the production requirement of the phosphorus ore pellet that to meet into stove acidity quotient be Mk=0.75 ~ 0.85.
The intermediate product that the present invention makes full use of Production Flow Chart as auxiliary material direct reuse in Production Flow Chart, namely with the middle acid sludge of two water thing method wet method phosphoric acid manufacture process after adjustment acidity, make and produce ground phosphate rock pelletizing binding agent used, by P in ground phosphate rock pelletizing
2o
5content improve 8 ~ 10%.Also can enter the shaping use of stove to the ground phosphate rock of acidity quotient Mk < 0.75 or Mk > 0.85, the pellet produced can enter stove without the need to additionally adding silica.Achieve efficient circulation and the comprehensive utilization of phosphate rock resource.
