Abstract
Description
Claims (3)
- The wet method phosphoric acid manufacture process of 1 one kinds of water-saving and emission-reducings, it is characterized in that this technology is before the phosphorus ore slurry enters extraction tank, ore pulp is carried out following pre-treatment: the ore pulp that phosphorus ore and water form after wet wheeling machine grinds, separate through cyclone separator, underproof coarse particles is discharged from the swirler bottom and is reentered the grinding machine grinding, the qualified ore pulp for moisture 50% that discharge at the swirler top enters Hhigh-efficient thickener and carries out densely, pumps into filter then to filter; Breeze after the filtration, a part is transported to the breeze hopper through belt, is delivered to metering screw through disk feeder, and the metering back adds tempering tank; Another part breeze is then delivered to the breeze warehousing and is deposited, and when grinding system is shut down, to rotary conveyor, delivers to tempering tank with the driving grasping operation then; Enter the breeze of tempering tank and under the stirring action of tempering tank agitator, react,, extract, produce dilute phosphoric acid according to traditional method by pumping into phosphoric acid by wet process extractive reaction groove from rephosphorization acid, the washing water of phosphoric acid by wet process; The water that filter is separated is after collecting, and pump is mixed into grinding machine with phosphorus ore after metering and grinds to wet wheeling machine, reuses.
- 2 according to the described production technique of claim 1, it is characterized in that described filter is pottery or turntable type filter or band filter; One or more is set is arranged in parallel; Independent operating or many operations simultaneously.
- 3 according to the described production technique of claim 1, it is characterized in that used breeze granularity is-200 orders~60 orders; Breeze after the filtration is moisture less than 10%; The material that enters tempering tank is 60%~75% through the slip solid content that reaction forms.
