The flue gas desulfurization reaction inslot is equipped with the stirring leaf, the settling basin bottom row of being equipped with cinder notch. The utility model relates to a phosphoric acid by wet process desulphurization unit, effective excessive sulphuric acid in the desorption phosphoric acid by wet process, sulphuric acid has obtained abundant application, has reached the effect that improves the phosphoric acid by wet process quality and reduce the phosphoric acid by wet process cost.
Description
Technical field
A kind of phosphoric acid by wet process desulfurizer of the utility model, relates to composite fertilizer's preparation facilities field.
Background technology
Application mid low grade phosphate rock is produced in phosphoric acid by wet process process, owing to needing to reach higher percentage extraction and good gypsum strainability, need to keep a certain amount of excess sulfuric acid in extraction process, when producing phosphorus ammonium with mid low grade phosphate rock, because excess sulfuric acid exists, phosphorus ammonium nutrient can be reduced.
Summary of the invention
For solving the problem that when phosphoric acid by wet process causes producing phosphorus ammonium because sulfuric acid exists, nutrient reduces, the utility model provides a kind of phosphoric acid by wet process desulfurizer, can excess sulfuric acid in effective elimination phosphoric acid by wet process, make sulfuric acid obtain abundant application, reach the effect improving phosphoric acid by wet process quality and reduce phosphoric acid by wet process cost.
The technical scheme that the utility model adopts is:
A kind of phosphoric acid by wet process desulfurizer, comprises phosphoric acid by wet process volume pump, phosphorus ore ore pulp-measuring pump, and described phosphoric acid by wet process volume pump, phosphorus ore ore pulp-measuring pump connect desulphurization reaction groove, and desulphurization reaction groove connects settling bowl by mashing pump, and settling bowl connects de-sulfuric acid storage tank.Be provided with paddle in described desulphurization reaction groove, bottom described settling bowl, be provided with slag-drip opening.
A kind of phosphoric acid by wet process desulfurizer of the utility model, phosphoric acid by wet process is after volume pump metering, the desulphurization reaction groove entering band paddle reacts with phosphorus ore flowsheet of slurry agitation after metering, and reacted slip enters settling bowl through shurry pump, and namely the phosphoric acid by wet process after clarification can be used for the production of phosphorus ammonium.Precipitation slag in settling bowl contains the unreacted phosphorus ore of part, phosphoric acid, returns Wet-process Phosphoric Acid Production system.
A kind of phosphoric acid by wet process desulfurizer of the utility model, can excess sulfuric acid in effective elimination phosphoric acid by wet process, and sulfuric acid obtains abundant application, reaches the effect improving phosphoric acid by wet process quality and reduce phosphoric acid by wet process cost.
