Box, anchor agitator such as a slow stirrer propeller stirrer type stirrer clover, suitable for high viscosity fluid mixing, heat transfer or reaction processes. Often in laminar flow operation, generating a horizontal hoop streams, such as inflammation of the flap or angle of the airfoil, increase the blade near the vortex. Fourier and may need to increase the beam in accordance with the paddle to increase the stirring range. For medium viscosity μ range <105cP, speed n = 1 ~ 100rpm. A315 axial impeller and domestic development Dekay developed new impeller flow impeller is used for gas-liquid dispersion system, which is characterized by the horizontal projection area of ??the impeller blade projection proportion (eg area ratio) of 87 % (4 leaves 45 ° pitched blade turbine disc was 42%). Power number Np value is much smaller than the straight blade disk turbine. But this dispersion capability inferior to disk turbine impeller, in fact, this is often associated with disk turbine impeller combination. Such as promoting multi-fermenter stirrer stirrer, the underlying performance is still good dispersion double disk turbine propeller stirrer, the upper use A315 impeller, increasing the mixing of the entire tank. Application results show that the combination of low energy consumption mix, and can improve the fermentation index, achieved significant economic benefits. Should blender biochemical fermentation equipment in addition to traditional straight blade disk turbine, turbine disc along curved arrow outer leaf disc turbine propeller stirrer pictures, and pitched blade turbine disc is a good choice. Pitched blade turbine disk has some shearing action, can produce a strong axial flow circulation, get better gas-liquid dispersion, gas holdup and heat transfer coefficient, and stirred less power. Because of the tilt blade, increasing the role of the blades on the cover gas, generic point speed is also low. Therefore pitched blade disk turbine is an excellent device, it has been widely used in recent years.
