Description
Technical field
The present invention relates to a kind of crystallization processes equipment, more specifically, it relates to a kind of efficient crystallization system.
Background technique
For a crystallization process, the quality of process conditions directly affects the final mass of crystalline product.Crystallization process
Operating parameter such as crystallization temperature, stirring rate, saturated concentration etc. may influence the purity of crystal product, size distribution and
The yield of process.The technics comparing of the domestic crystallization of research at present is more, but studies the specialized factory of crystallizer and few, in fact
Under mature process conditions, only matched equipment can be only achieved the requirement of technological design, can just produce and meet technique
Product.
Domestic crystallizing tank at present is all using simple crystallizing tank, it is exactly the cylinder of a jacketed, an anchor formula
Blender composition.Mainly on barrel, the temperature of barrel will be transmitted to center for the heat transfer of collet, and quick turbulent flow is needed to stir
It mixes, can realize, then anchor formula stirring is mainly circulation, he is it is difficult to ensure that the mixing up and down stirred, inside and outside mixing；Thus very
Difficulty achievees the effect that turbulent flow, internal-external heat exchange are very poor, so longer crystal is all that size is uneven, and anchor formula
Shearing force is bigger, plays the role of destroying dispersion to the crystal grown, causes to be additionally formed excessive nucleus, thus longer
Crystal be also it is very tiny, it is in irregular shape, there is a problem of that product yield is not high.

Preferably, the impeller includes four blades, the every blade is set as fan-shaped, four blades and water
Plane is respectively formed the angle being gradually increased.
By using above-mentioned technical proposal, blade has sector structure, has very big horizontal projected area, prevent in fluid
In lifting process, the reflux of minicrystal is sunk, and improves production stability.
Preferably, the blade is set as spiral camber.
By using above-mentioned technical proposal, the blade of spiral camber can generate very strong axial thrust in rotation, crystalline substance
Body is drunk up from bottom, in the reactor heat exchange, while decreasing the radial flow of material generation, and substantial radial stream is avoided to rush
Reactor wall is hit, and generates radial shear power, destroys the particle of crystal.Radial flow is reduced, radial shear power is also possible to prevent
Destruction is generated to the flow pattern up and down of stirring, a part of crystal is caused to flow back into bottom.
Preferably, rounded corner at the end angle of the blade.
By using above-mentioned technical proposal, fairshaped blade can reduce energy consumption, than original gate stirrer, energy conservation
20% or more.
Preferably, the lateral wall concentric arry of the reactor has multilayer baffle, the inner tank wall is again provided with
Baffle, the baffle tilt down, and the baffle of the reactor and the baffle of tank body are staggered, and deposit between the adjacent baffle
In gap.
Gear can be first rested on after the tiny nucleus for supporting crystal zone formation is fallen on baffle by using above-mentioned technical proposal
On plate, after allowing nucleus to there is time enough growth, nucleus to grow into larger crystal, tank will be fallen in along baffle due to self weight
Body bottom.Baffle can also prevent the fluid operation of stirring too fierce, allow between crystal and collide with each other, crystal is broken up and is smashed
Or bonding is agglomerating, the totally different various crystal of formation rule influence crystallization effect and product appearance quality.
In conclusion the present invention achieves following effect:
1. realizing the increase of heat exchange area by the cooperation of cooling chamber one and cooling chamber two, improving heat exchange efficiency；
2. realizing the raising of crystalline quality by the cooperation of impeller and baffle.
