ULTRASONIC COAGULATION METHOD Russian patent published in 2021 - IPC B01D51/08 B01J19/10 

FIELD: gases cleaning technologies.

SUBSTANCE: invention relates to technologies for cleaning gases from foreign inclusions of solid and liquid particles by exposing them to ultrasonic vibrations of high intensity, and in particular to methods of ultrasonic coagulation of particles less than 2.5 microns in size. The method of ultrasonic coagulation consists in passing a gas flow with foreign particles between two surfaces, one of which emits and forms ultrasonic vibrations, and the second reflects the vibrations passed through the stream, the radiation of ultrasonic vibrations is carried out by a bending-vibrating plate, on a flat emitting surface of which maxima and minima of vibrations are formed, alternating sequentially at a distance from each other corresponding to half the wavelength of bending vibrations in the plate material at a frequency of 22 kHz with an intensity of 140-150 dB, the gas flow is formed by introducing it in the central part of the reflective surface and spread to peripheral areas of surfaces.

EFFECT: increasing the efficiency of coagulation by 3-10 times by increasing the amplitude of oscillations, creating vortex flows between the emitting and reflecting surfaces, which make it possible to increase the time of ultrasonic action on each particle and create zones of local increase in the concentration of submicron particles.
