Chinese patent CN 102068955 A disclose a kind of flocculation reactor with special-shaped spoiler, the baffle plate of various cross sectional shapes being installed and being had certain thickness requirement is set at this reactor wall, and this baffle plate and reactor wall are smoothly connected, in order to improve flocculating effect and to avoid it to produce failure by shear effect to floc sedimentation.The feature of this patent is to avoid producing shear action.
Chinese patent CN 102302908 A have invented the baffle plate in a kind of tank diameter, at reactor wall, install by some small front aprons to keep each other gapped state to be arranged the baffle group forming, every small front apron all adopt stainless steel also embedded reinforcing bar it is directly connected with still wall.
Chinese patent CN 201415128Y has invented a kind of stirred tank with spiral line-shaped curved baffles, spiral line-shaped curved baffles is fixedly welded on inner wall of kettle, spiral line-shaped curved baffles and stirred tank axial clamp angular region are 30 °-60 °, spiral line-shaped curved baffles quantity is 3-6 and is uniformly distributed, and the width of spiral line-shaped curved baffles is 0.05 ~ 0. 15 with the ratio of kettle internal diameter: 1.The defect that this technology exists is: convection cell shearing dispersibility a little less than.
In above-mentioned patented technology, baffle arrangement and characteristic size continually varying horizontal reactor structure are incompatible, even also can weaken the shear action of baffle plate, therefore, are not suitable for Horizontal internal circulating stirred reactor.
Summary of the invention
The object of the invention is to overcome the defect of above-mentioned prior art, the shearing dispersibility in a kind of efficient hardening axial flow flow pattern is provided, thereby reach the Horizontal internal circulating stirred reactor of circulation and the mixing of fresh material Quick uniform.
The present invention adopts following technical scheme to realize:
A kind of Horizontal internal circulating stirred reactor, comprise reactor shell, be arranged on guide shell in reactor shell, with agitating device and the end cap end socket of stirrer paddle, it is characterized in that: on the described guide shell inwall of reactor reducer, be provided with the baffle plate with gradual change width.
Described barrier width is 1/12 ~ 1/8 times of each lateral cross section diameter of guide shell reducer.
Described baffle plate is 4 ~ 8, is evenly arranged.
Described baffle plate is installed from wall, and it is from span from being 1/120 ~ 1/80 times of each lateral cross section diameter of guide shell reducer.
Described guide shell adopts 4-6 bar axial diversion plate whole or splicing to be uniformly distributed support.
Described stirrer paddle is that a kind of projected outline of mounted blade is that one jiao of fan-shaped, blade outer rim is carried out crooked novel blade with certain curvature radius, and described radius of curvature is 1/4 ~ 3/4 of described diameter of propeller blade D.
Described end cap end socket forms by flange, bent bodies with the containment member of axis hole.
Described bent bodies is formed by connecting by three sections of circular arc bodies, and the ratio of the inside diameter D of the radius of curvature of each circular arc body and described end cap end socket is: R1/D=0.406 ~ 0.813, R2/D=0.166 ~ 0.250, R3/D=0.144 ~ 0.194; Corresponding 1=12 ° ~ 40 ° of central angle value α, α 2=36 ° ~ 101 °, α 3=34 ° ~ 120 °.
The present invention is according to the mobile mixing of reaction system and the characteristic requirements of dispersion, guide shell internal face at the material inlet position of Horizontal internal circulating stirred reactor is installed the deflector apron changing according to cross-sectional diameter, changed tangentially rotatablely moving that the fluid that accelerates because of cross-sectional constriction produces under the impeller induction of High Rotation Speed, make the fluid turbulization of main body axial flow shear simultaneously, thereby strengthened circulation of fluid end materials and newly entered the shearing dispersibility of material, and it is mobile to guide fluid to produce axial circulation, finally make material quick, evenly mix, meeting the required material of reaction distributes and mass transfer condition, guaranteed the quality of product.
