Description
Technical field
The utility model relates to sulfate process titanium dioxide production technical field, specifically a kind of acid hydrolysis solution and flocculant mixing stirring device.
Background technology
Because acid hydrolysis solution viscosity is larger; granule mechanical admixture especially colloidal impurity; can not be separated by means of simple natural subsidence method; industrial production generally adopts and adds flocculant, as antimony oxide-iron sulfide, flocculant tannic acid-Niu glue, flocculating setting agent dimethylamine modified polyacrylamide (AMPAM) strengthen effect of settling.
Stirring is the necessary condition that flocculant fully contacts with acid hydrolysis solution, and stirring intensity is weak, the time is short, and effect of settling can be caused bad; Stir flocculated particle that is too strong, overlong time generation broken again, unfavorable to sedimentation.AMPAM also will flow with acid hydrolysis solution and add simultaneously, just can mix.If acid hydrolysis solution and flocculant stir the uneven effect of settling that causes and be obviously deteriorated, the purified liquor outlet concentration of hydraulic mixture of subsider increases, and bottom sediment water content increases, and causes adverse effect, increase the workload of follow-up washery slag operation simultaneously to follow-up Crystallization Procedure.
At present, main solution is as follows: 1) at the end of acidolysis blowing pipeline, the top of settling tank by flocculant and stream add, such flocculant addition manner very easily causes the uneven of mixing, should not advocate; 2) after acid hydrolysis solution all puts into settling tank, blast compressed air in the centre of settling tank and the flocculant added and acid hydrolysis solution are uniformly mixed.This method is better to the settling tank effect that volume is less, and for larger settling tank, compressed-air actuated mixing effect is bad; 3) static mixer installed by the pipeline transporting to settling tank at acid hydrolysis solution, and acid hydrolysis solution and flocculant are fully mixed in static mixer.This method flow process, equipment are simple, and mixed effect is good.Shortcoming is because acid hydrolysis solution is containing solid particle, easily blocks static mixer.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provides that a kind of structure is simple, production cost is low, is easy to process, a kind of acid hydrolysis solution of environmentally safe and flocculant mixing stirring device.
The utility model solves the technical scheme that its technical problem adopts: this mixing stirring device comprises surge tank, mixing tank and subsider, the side, top of mixing tank is communicated with surge tank by pipeline, the top opposite side of mixing tank is communicated with flocculant storage tank by pipeline, the top of mixing tank is communicated with subsider by overflow pipe, mixer is provided with in mixing tank, mixing tank inner side is provided with drainage conduit, the bottom of drainage conduit is in the bottom of mixing tank inner chamber, the top of drainage conduit is communicated with blow-down pipe, and the top of drainage conduit is communicated with overflow pipe.
The top of described surge tank is communicated with acid hydrolysis tank by pipeline.
The bottom of described subsider is communicated with sludge pipe, and the top of subsider is communicated with clarified solution pipe.
The inwall of described subsider and clarified solution pipe connectivity part is provided with baffle plate.
A kind of acid hydrolysis solution of the present utility model and flocculant mixing stirring device are compared to the prior art, have reasonable in design, structure simple, be easy to processing, the feature such as easy to operate, can ensure that enough mixings time (6-8min) make flocculant mix with acid hydrolysis solution; The foam formed in flocculant whipping process can be got rid of, there is no foam to ensure to enter in the flocculant of settling tank and acid hydrolysis solution, improve sedimentation quality; Mixing tank in this device there will not be the situation of blocking, ensure that the stability of operation, continuity.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
A kind of acid hydrolysis solution of the present utility model and flocculant mixing stirring device, its structure comprises surge tank 1, mixing tank 2 and subsider 3, and the side, top of mixing tank 2 is communicated with surge tank 1 by pipeline, and the top of surge tank 1 is communicated with acid hydrolysis tank 4 by pipeline; The top opposite side of mixing tank 2 is communicated with flocculant storage tank 5 by pipeline, the top of mixing tank 2 is communicated with subsider 3 by overflow pipe 11, the bottom of subsider 3 is communicated with sludge pipe 7, the top of subsider 3 is communicated with clarified solution pipe 8, and subsider 3 and the inwall of clarified solution pipe 8 connectivity part are provided with baffle plate 12; Be provided with mixer 6 in mixing tank 2, mixing tank 2 inner side is provided with drainage conduit 9, and the bottom of drainage conduit 9 is in the bottom of mixing tank 2 inner chamber, and the top of drainage conduit 9 is communicated with blow-down pipe 10, and the top of drainage conduit 9 is communicated with overflow pipe 11.
Operation principle: the acid hydrolysis solution from hydrolysis procedure enters surge tank 1 from acid hydrolysis tank 4, mixing tank 2 is entered via surge tank 1, meanwhile flocculant enters mixing tank 2 through flocculant storage tank 5,6-8min is stirred by the mixer 6 in mixing tank 2, acid hydrolysis solution and flocculant are fully mixed, because the bottom of drainage conduit 9 is in the bottom of mixing tank 2 inner chamber, acid hydrolysis solution is discharged by the lower port of drainage conduit 9, therefore can not be taken out of being uniformly mixed the foam produced in process, effectively eliminated the foam formed in flocculant whipping process.Acid hydrolysis solution after mixing enters continuous subsider 3, and acid hydrolysis solution is clarified solution and mud in this sedimentation.Clarified solution enters subsequent processing by clarified solution pipe 8: heat filtering-crystallization; Mud is discharged by sludge pipe 7 and is carried out washery slag and the feed liquid reclaiming attachment.
By detailed description of the invention above, described those skilled in the art can be easy to realize the utility model.But should be appreciated that the utility model is not limited to above-mentioned several detailed description of the invention.On the basis of disclosed embodiment, described those skilled in the art can be combined different technical characteristics, thus realize different technical schemes.
