Complex mixing system with stages consisting of propeller mixers of high diameter ratio, where the blades are provided with flow modifying elements, whereby the energy proportions spent on dispersion of the amount of gas injected into the reactor, homogenization of the multi-phase mixtures, suspension of solid particles, etc. and the properties corresponding to the rheological properties of the gas-liquid mixtures and to the special requirements of the processes can be ensured even in extreme cases. Open channels (5) opposite to the direction of rotation are on the blades (4) of the dispersing stage (2a) of the propeller mixers (2) fixed to a common shaft, where the channels (5) are interconnected with gas inlet (7). The angle of incidence of a certain part of the blades (4) of mixing stages (2b, 2d) used for homogenization and suspension is of opposite direction and the length is shorter and/or the angle of incidence is smaller than those of the other blades. Baffle bars (8) are on the trailing end of the blades on a certain part (2c) of the propeller mixers used similarly for homogenization and suspension, and/or auxiliary blades (12) at an angle of max. 20.degree. to the blade wings are arranged above or below the trailing end of the blades (FIG. 1 and 6).
A mixer for dispersing a gas in a liquid, comprising:
