Description
Technical field
The utility model belongs to crystallization agitating device technical field, specifically, relates to a kind of agitated crystallizer with segmented guide shell structure.
Background technology
At chemical field; the industries such as such as pharmacy, food, petrochemical industry; in a lot of production, be all accompanied by crystallization process; and reaction crystallization process is a complicated heat transfer, mass transport process; the process that produces indissoluble or insoluble solid matter by means of chemical reaction, the second process such as be conventionally also accompanied by the aging, coalescent of crystal and break.Because saturation degree and the mixture homogeneity of solution are the important factor in order of reactive crystallization, and good circulation is one of essential condition of crystal growth, therefore mixes reaction crystallization process is often had to larger impact.
Current existing reactive crystallization device, at the surperficial wall of industrial crystallization equipment, there is dust, solid impurity etc., therefore be easy to produce the phenomenon of crystal wall built-up, and in the process of crystal growth, due to the continuous rotation of blade, can bump with crystal continually, very easily cause crystal fracture.For example, normal tape guide shell agitated crystallizer can be strengthened the overall axial flow of upper and lower liquid in tank diameter, improve the mixed effect of liquid, and the shear rate at the agitated crystallizer inner fluid with guide shell is lower, but the lower phenomenon that is not enough to solve crystal wall built-up of fluid motion speed outside guide shell; And the agitated crystallizer that has an anchor formula oar due to the blade of anchor formula oar from wall close to, can under lower rotating speed, produce larger wall shear rate, therefore the shear rate of groove inner fluid is lower, but having in the agitated crystallizer of anchor formula oar, in groove, central area and blade place rate of flow of fluid difference are very large, easily produce the phenomenon that swirls and cause groove flow field skewness, crystallization effect is also had a great impact; In current industrial crystallization process, also normal use without the larger multilayer oar reactor of the guide shell D/T ratio of groove footpath (diameter of stirring paddle with) carried out reactive crystallization, under this operating environment for reach full groove mix need to be higher rotating speed, although obtained more uniform flow field and larger wall shear rate, but because rotating speed of agitator is higher and blade number is more, can produce larger fluid shearing speed, easily occur the phenomenon of crystal fracture.
Therefore, with regard to existing agitated crystallizer, for obtaining preferably crystallization effect, must effectively improve mixture homogeneity in reactor simultaneously, solve crystal and occur wall built-up, and reduce as far as possible fluid shearing speed in case the situation of crystal fracture, existing stirred crystallization device is difficult to solve this three problems simultaneously.
Summary of the invention

Agitated crystallizer with segmented guide shell structure described in the utility model, described agitated crystallizer is containing 2-5 piece outer baffle 5,2-5 piece Internal baffle 3, the main blade 6 of a 2-5 press-down type and top uncoupling type metaplasm leaf 7.
Agitated crystallizer with segmented guide shell structure described in the utility model, described paddle is axial-flow type CBY oar type.
Agitated crystallizer with segmented guide shell structure described in the utility model, the diameter ratio of described diameter of stirring paddle and cell body 1 is 0.9-0.98.
Compared with prior art, the agitated crystallizer with segmented guide shell structure described in the utility model has following features and advantage:
1), can require guide shell to be divided into multistage and to arrange in pairs or groups many oars according to the liquid level of concrete operations, guide shell under this structure makes flow pattern in groove have more directionality, full groove mixes more even, between two sections of guide shells, there is slit, slit is slightly wider than connection rod, to alleviate the phenomenon that occurs fluid short circuit in whipping process;
2), paddle adopts the coaxially axial-flow type CBY oar type with accessory lobes, in cylinder, main lobe adopts press-down type, the outer accessory lobes of cylinder are top uncoupling type, this has increased the D/T of tank diameter on the one hand, make D/T can reach the scope of 0.9-0.98, promote the fluid flow rate outside guide shell and between cell wall, can produce larger wall shear rate, alleviate the phenomenon of crystal wall built-up, can strengthen on the other hand guide shell internal flow moves downward, the circulation style that guide shell external fluid moves upward, further strengthen the mixture homogeneity in groove, and solve the problem that crystal easily sinks to the bottom,
