METHOD OF ACTIVATION OF MIXING PROCESS OF LIQUID MEDIA AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC B01F3/08 B01F7/26 B01F11/00 

FIELD: technological processes.

SUBSTANCE: invention relates to general-purpose mixing methods for various physical, chemical and hydromechanical (dispersion, emulsification, homogenisation, foaming, decomposition) processes with liquids and can be implemented in mixers of various types with rotating mixing devices in fixed tanks. Method of activation of mixing of liquid media, in which mixture is forced, with frequencies ω1 and ω2, by means of rotors with perforated disks simultaneously set rotary with pulsations of speed ±ε and radial-axial oscillations, at the same time, swirling opposite flooded jets are formed and their mixing path length is increased at volumetric circulation of said jets, wherein parameters of forced motions of mixture are controlled by relationships in form of transformed system of Navier–Stokes equations, taking into account all said motions of mixture, increasing if necessary either radial or axial components of velocity of formed jets, according to the invention, at least two areas of the mixture are simultaneously set to counterrotations with speed pulsations and radial-axial oscillations, at the same time in each region there formed are own swirling oppositely directed in axial direction submerged jets, and then forced in synchronization in radial direction of intersections of trajectories of jets of one region with opposite flooded jets of neighboring area, thereby form a strange attractor of swirled trajectories of exponentially diverging opposite jets of neighboring areas with significant increase in volume circulation of said jets. Device includes shaft with perforated discs, arranged in housing with possibility of reciprocal axial movement from drive, according to invention, in upper part of housing with possibility of rotation and radial rocking due to bellows are arranged at least two shaft-rotors with perforated disks and own drives of pulsating-rotary action, on other ends of each of them plates are rigidly attached, conjugated with common spring-loaded and axially movable counterbody, in fact, the latter is equipped with device to adjust force of its pressing to plates.

EFFECT: high activity of the mixing process by increasing the number of regions, each of which forms self-swirled opposing jets, which together form a strange attractor of swirled trajectories of exponentially diverging opposite jets of neighboring areas, which significantly increases interaction intensity and volumetric circulation of jets and reduces time of transition from laminar to turbulent mode, which reduces duration of mixing of liquid media.
