ROTARY PULSE APPARATUS AND METHOD OF ITS OPERATION Russian patent published in 2019 - IPC B01F3/08 B01F3/12 B01F7/28 

FIELD: machine building.

SUBSTANCE: invention relates to rotary-pulsed apparatus and can be used in chemical, pharmaceutical, food and other industries, petrochemistry and oil processing for carrying out processes of dispersion, mixing, emulsification, extraction, liquid extraction, cavitation treatment, deagglomeration of nanoparticles, reactions in heterogeneous liquid-solid or liquid-liquid systems and other processes, in which local input of large amount of energy into small volume is required. Rotor-pulse apparatus comprises a housing with coaxial cylindrical or conical stator coaxial to it, consisting of fixed ribs, coaxial to it cylindrical or conical rotor corresponding to stator shape with ribs installed on it, with formation between the fixed stator ribs and the rotor ribs of the gap rotor, between the adjacent ribs of the rotor and between the adjacent ribs of the stator there are holes for passage of phases, and the shaft of the rotor is connected to the drive, the housing is equipped with a central branch pipe for input of phases and peripheral branch pipe for withdrawal of products, and between the housing and the stator there is an annular chamber, to the annular chamber in the lower part of the housing one or several resonance chambers filled with liquid is connected, at the opposite end of each of the resonance chambers there is an outlet valve, resonant chambers are made with possibility of smooth adjustment of their volume, preferably by means of adjustable position pistons, connected to actuators, and to housing one or more pressure sensors are connected, signal from which is supplied to controller, with possibility to control volume of resonance chambers by supply of control signal to actuators. Method of rotary pulse unit operation consists in supply of initial components to the housing of the apparatus, removal of products from it, in transmission of rotary motion to the rotor, wherein during operation of apparatus using controller and actuators there is a smooth change in volume of each of resonance chambers so that signal coming from pressure sensors, reached maximum value corresponding to resonance of oscillations in system "housing - resonant chambers".

EFFECT: invention provides higher efficiency of dispersion processes, intensified mass transfer, reduced power consumption due to accurate adjustment and implementation of stable resonance pulsations on basic harmonic oscillations in additional elements of the apparatus - one or more resonance chambers.
