Half tube and parabolic disk turbine agitator runoff agitator, its blades are concave arc and paraboloid respectively, with strong radial displacement and dispersion capacity. Under the same power, its mass transfer coefficient is more than 30% higher than that of flat blade disk turbine, the gas holding capacity is increased by more than 40%, and the power consumption is relatively low. Therefore, it is especially suitable for dissolved oxygen operation similar to fermentation process, It is also applicable to gas dispersion, absorption, mixing, mass transfer and other operations under other requirements.
