The invention relates to the field of dispersion and mixing of single and multiphase systems and can be used in the chemical as well as in the food industry for the preparation of homogeneous mixtures.

The purpose of the invention is to intensify the process and increase productivity.

FIG. 1 shows a device for processing media, a section; in fig. 2 is a section A-A in FIG. one.

The medium processing device comprises a cylindrical body 1, supplying 2 and discharging 3 pipelines. Case I has check valves 4 and generator 5

For the purpose of additional processing of the mixture in nozzle 6, nozzle elements 8 are installed, forming the shape of a Venturi pipe in orthogonal section. In a narrow section of the Venturi pipe, the pressure drops to the value of the saturated vapors of the dispersible liquid and hydrodynamic cavitation occurs.

As a result of cavitation, periodically collapsing ka-10 are formed in the liquid. The density of the medium at the points of origin of cavitation varies significantly, from the density of saturated vapor to the density of the liquid.

Pus 1 has a cylindrical vortex-forming nozzle 6.

The reflector 7 is located at the end of the body and is made conoidal. In the vortex-forming nozzle 6, nozzle elements 8 are installed in parallel, forming orthogonal sections with channels having a Venturi tube profile. A cylindrical insert 9 is coaxially mounted at the outlet of the nozzle b.

The device works as follows.

During the operation of the generator 5, a pressure pulse is transferred to the liquid with the dispersible material, which enter the device through the supply pipes 2. The liquid-dispersible material mixture passes through the check valves 4 and enters the cylindrical vortex-forming tube 6 equipped with a cylindrical insert. At the outlet of the nozzle, the boundary layer is torn off, twisted, and complex vortex rings are formed from the mixture, which contribute to more intensive mixing of the mixture and have a significant flight range. The vortex rings move along the axis.

Thus, when cavitation arises and develops, the materials are subject to multiple impacts, as a result of which the materials being processed are dispersed and mixed.
