Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model is a kind of sal glauberi crystallization apparatus, including cylinder 1, material liquid import
Pipe 15, freezing liquid inlet tube 5, freezing liquid return duct 6, clarified solution outlet 7, crystal outlet 17, outer cooler 18 and sedimentation
The inside of tower 19, the cylinder 1 is vertically disposed with baffle 16 and demarcation strip 10, the baffle 16 and demarcation strip 10
Cylinder 1 is divided into settling section 4, crystal region 3 and decanting zone 2, is settling section 4, demarcation strip 10 and baffle 16 on demarcation strip 10
Between be crystal region 3, baffle 16 using lower part as decanting zone 2, the crystal region 3 be also equipped with one only have side wall, without upper cover
With the guide shell 11 of bottom, with baffle 16 and demarcation strip 10 there are gap, 11 inside of guide shell is arranged at the guide shell 11 both ends
There are the blender transmission shaft 9 perpendicular to 1 top of cylinder, 9 upper end of blender transmission shaft to be connected with the speed regulating motor 8 on 1 top of cylinder,
9 lower end of blender transmission shaft is connected with propeller-blade 14, and propeller-blade 14 is placed in inside guide shell 11；The freezing liquid
5 one end of inlet tube is connected with outer cooler 18, and the other end is inserted into cylinder 1 lower part for being located at crystal region 3, the material liquid import
Pipe 15 is inserted into 1 inside of cylinder and between freezing liquid inlet tube 5 and baffle 16,6 one end of freezing liquid return duct and outer cooler
18 are connected, and the other end is inserted into the top that cylinder 1 is internally located at crystal region 3, and the demarcation strip 10 is arranged in freezing liquid return duct 6
Exit, 1 bottom of the cylinder is tapered, and 1 bottom of cylinder is provided with crystal outlet 17, the crystal outlet 17 with it is heavy
Tower 19 is dropped to be connected.
When sal glauberi crystallization apparatus works, material solution is entered from material liquid inlet tube 15 inside crystallization apparatus,
Material solution inside crystallization apparatus is cooled down from freezing liquid inlet tube 5 into outer cooler, after cooling in outer cooler
Solution returns to the crystal region 3 of crystallization apparatus by freezing liquid return duct 6, and under the action of baffle, the substance in solution is in water
It is distributed and on plane section, and top is raised slowly to from the lower part of crystal region.The raw material come in from material liquid inlet tube 15 is molten
Liquid enters outer cooler 18 from freezing liquid inlet tube 5 again and is cooled down, in such a manner, solution crystal region 3 with it is outer cold
But it is recycled between device 18, endlessly material solution and cooling solution is provided for crystal region 3, when the temperature of crystal region 3
When generating the corresponding temperature of saturation less than sodium sulphate, the sal glauberi crystal in solution will be precipitated, formed nucleus and after
Continuous growth.Due to the effect of stirring, cycle is generated in the space that solution is formed among guide shell and on the outside of guide shell with cylinder 1
Flowing, brilliant circumnuclear sodium sulphate is precipitated on nucleus forms fine grain, and degree of supersaturation tends to be saturated.Due to the effect of stirring, carefully
Saturated solution around brilliant makes the solution around fine grain reach saturation again, new sodium sulphate is thin constantly by solution remotely
It is precipitated on crystalline substance, this process constantly recycles, and crystal is made constantly to grow up.In crystal region, since fluid flows from bottom to top, meeting
Upward lift is generated to crystal grain, and crystal grain also has downward gravity, the crystal in solution is suspended in solution at this time,
When crystal grain, which is grown up, is more than upward lift to its gravity, 3rd area of crystallization will be detached from and drop to decanting zone 2, eventually by crystal
Outlet 17 is discharged from sal glauberi crystallization apparatus.The smaller crystal grain in part, its own gravity are less than the lift being subject to,
It will enter in the cycle between outer cooler and crystal region 3, be contacted with subsequent supersaturated solution subsequent with material solution
Continuous growth, drops to decanting zone 2, the crystal of decanting zone 2 is discharged to by crystal outlet 17 when its gravity is more than lift
Sedimentation tower 19 further settles.Material solution mixed with solution after cooling after being sent to crystal region 3 and continuously by
Cooling, degree of supersaturation slowly reduces after forming supersaturated solution, with crystal contact, degree of supersaturation base when reaching 3 top of crystal region
This elimination, with the continuous entrance of material solution, the solution that the degree of supersaturation on 3 top of crystal region substantially eliminates can flow up
Into settling section 4, the solution after clarification is discharged by clarified solution outlet 7 outside sal glauberi crystallization apparatus.
If the solution in crystal region 3 can obtain enough cycles, mixing, crystallization effect and crystalline rate can be more preferable, are
Reach said effect, it is preferred that the material liquid inlet tube 15, freezing liquid inlet tube 5 and freezing liquid return duct 6 and cylinder 1
Side wall is tangent.The outflow direction of liquid and liquid in freezing liquid return duct 6 in material liquid inlet tube 15 and freezing liquid inlet tube 5
It flows into direction and forms a direction of rotation, can generate certain cycle naturally using the disengaging of material solution, make in crystal region 3
Solution it is more fully mixed, crystallization effect is more preferable.
Since metabisulfite solution needs just reach degree of supersaturation at a specific temperature, ten water are precipitated to crystallize
Sodium sulphate, and material solution can be constantly filled in crystal region 3, therefore temperature has certain variation, in order to ensure that crystal region is kept
Best crystallization temperature, it is preferred that the crystal region 3 is additionally provided with thermo detector 12, and thermo detector 12 is located on the side wall of cylinder 1, this
Sample can understand the temperature in crystal region 3 at any time by thermo detector 12, to ensure crystallization effect.
The state that circulates stablized in crystal region is more favorable for solution crystallization, and solution convolution in order to prevent destroys cycle effect
Fruit, it is preferred that the madial wall of the guide shell 11 is additionally provided with deflector 13, and the deflector 13 is obliquely installed, and along same
Circumferencial direction tilts, as shown in Fig. 2, solution can be made to be formed in the counterclockwise direction along the inclined deflector of a circumferencial direction 13
One stable to circulate state, prevents solution from flowing back.
