ROTARY PULSATION DEVICE Russian patent published in 2019 - IPC B01F7/28 B01F3/08 B01F3/12 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for creation of pulse oscillations in fluid flow medium and can be used for intensification of emulsification, absorption and other processes in systems "liquid-liquid", "liquid-solid body". Rotary pulsation device comprises housing with inlet and outlet branch pipes, concentrically installed in it rotor and stator with channels in side walls of cylinders, sounding chamber, electric motor, wherein channels of rotor and stator are made opposite to each other at angle of 35° to the radial axis, wherein the rotor channels are in the form of a confusor, and the stator channels are in form of a diffuser, and the angle at the vertex of the cone forming the confusor and diffuser is 13–14°. Number of channels in stator and rotor is even, from 20 to 50.

EFFECT: high degree of dispersion and emulsification of solid and liquid phases of drilling and backfilling solutions, elimination of "idle run".
