Background
Stirring devices are widely used in many industries of industry. In a gas-liquid-solid three-phase system for polysaccharide fermentation, the growth of microorganisms needs breathing oxygen, so that sterile compressed air needs to be introduced. The oxygen in the air is transferred from the gas phase to the liquid phase and finally to the cell. Because the medium viscosity is large, the gas phase is difficult to enter the liquid phase, the mass transfer is difficult, and the existing stirrer can not meet the requirements of mixing and gas dispersion.
Disclosure of Invention
The invention aims to solve the technical problem of providing a special stirring device for viscous fluid mixing and gas dispersion, and solving the problems of medium mixing and gas dispersion in the polysaccharide fermentation process.
The technical scheme who solves above-mentioned technical problem and adopt provides a viscous fluid mixes and special agitating unit of gaseous dispersion, including the actuating mechanism on upper portion, the stirred tank of splendid attire medium, stretch into the axle in the cauldron and the installation by actuating mechanism and be located the agitator of axle lower extreme, dispose the gas distributor below the agitator. The ratio of the diameter of the stirrer to the inner diameter of the kettle is usually 0.35-0.6, and the stirrer comprises a hub at the central position, a disk which is integrated with the hub and surrounds the hub, a spiral cone upturned curved surface blade and a spiral cone downward-pressed curved surface blade which are positioned at the outer edge of the disk, and a backward-bent blade which is arranged at the lower side of the disk and integrated with the disk. The disc and the backward bending blade on the lower side of the disc are fixed on the lower half part of the hub, and the ratio of the diameter of the disc to the diameter of the stirrer is proper between 0.5 and 0.8. The spiral cone turn-up curved surface blade and the spiral cone push-down curved surface blade are manufactured in pairs, 1 pair, 2 pairs, 3 pairs or 4 pairs can be required according to the size of the kettle body, and the inner diameter of the circular ring position where the spiral cone turn-up curved surface blade and the spiral cone push-down curved surface blade are located is close to the half position of the radius of the circular disc. The backward bending blade is arranged between the two spiral cone upward turning curved surface blades and the spiral cone downward pressing curved surface blade. The distance between the gas distributor and the lower end of the backward bent blade is 50-100 mm, the diameter of the gas distributor is usually 0.6-0.8 times of the diameter of the disc, and the ventilation direction of the gas distributor is upward. Above-mentioned agitator passes through holding screw detachably with the help of the wheel hub upper half of self to be fixed epaxial can be along with its operation, and the back curve blade forms great radial streamline of centrifugation during the operation, and the center forms the negative pressure, inhales the gas that gas distributor came out fast, then goes into the air pocket that the back curve blade formed and disperses, has better gas dispersion ability and power consumption and hangs down.
After the gas is dispersed by the backward-bending blades, the gas enters the stirring range of the spiral cone upward-turning curved surface blades and the spiral cone downward-pressing curved surface blades, when the spiral cone upward-turning curved surface blades and the spiral cone downward-pressing curved surface blades discharge fluid, a part of gas can be sucked into the rear parts of the spiral cone upward-turning curved surface blades and the spiral cone downward-pressing curved surface blades to form gas pockets to be dispersed again, the gas pockets touch the edges of the spiral cone upward-turning curved surface blades and the spiral cone downward-pressing curved surface blades to be broken again, the outer edges and the upper and lower edges of the spiral cone upward-turning curved surface blades and the spiral cone downward-pressing curved surface blades are made into saw-toothed shapes, and the secondary breaking effect is further intensified. During manufacturing, the edges of the sawteeth can be guided into round corners, so that people are prevented from being injured.
In addition, in the operation process, the spiral cone downward-pressing curved surface blade discharges fluid downwards, the spiral cone upward-turning curved surface blade discharges fluid upwards, an unstable flow field can be formed, the flow in the reactor is in a chaotic state, the turbulence degree of the fluid is improved, the utilization rate of energy input through the blades is increased, and the mixing efficiency of the fluid is further improved.
The invention has the advantages that the special design of the stirrer is matched with the gas distributor below the stirrer, so that the gas-liquid mass transfer capacity can be improved, the mixing efficiency of the fluid can be enhanced, the problems of mixing of high-viscosity media and gas dispersion are solved, and the stirrer is suitable for the ventilation stirring fermentation process of viscous materials, is also suitable for other gas-liquid reaction processes such as hydrogenation reaction, oxidation reaction and the like, and has high-efficiency mixing performance and gas dispersion mass transfer performance.
