ULTRASOUND CAVITATION FLOW REACTOR (VERSIONS) Russian patent published in 2012 - IPC B01J19/10 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to treatment of process fluids, mixes, suspensions, emulsions, etc, by ultrasonic field and excitation of cavitation inside the reactor. Proposed reactor has process fluid feed and discharge flow channel, ultrasonic converters, frequency-decreasing straps and fasteners of elements. Frequency-decreasing straps are made up of solid ring-like bulk acoustic transformer with trapezoidal cross section jointed with reactor pouter wall by its surface that corresponds to trapezoid smaller base. Surface of every straps corresponding to trapezoid larger base is provided with ultrasonic converters arranged without acoustic clearance. Reactor inner volume radius is a multiple of half the length of acoustic wave that causes cavitation in processed medium while distance from ultrasonic converters attachment plane to inner working volume is a multiple of odd number of acoustic wavelengths in transformer material. Reactor and channel allow processing process fluids in flow conditions. In compliance with first version, reactor is made up of 3D vessel with inner surface approximating to spheroidal surface. Note here that reactor is formed by cylindrical central sections with two taper sections that form the surface approximating to spheroidal one so that normal lines to the surface of sections are directed toward reactor center. Frequency-decreasing straps are secured on reactor cylindrical and taper sections without acoustic clearance and contact. In compliance with second version reactor is formed by two conical sections so, that normal lines are directed toward reactor center. Note here that frequency - decreasing straps are secured on reactor outer conical without acoustic clearance and contact.

EFFECT: higher efficiency of treatment, simplified process, expanded operating performances.
