- Abstract: The paper proposes and theoretically justifies an approach to improving the efficiency of coagulation of submicron suspended particles under the action of ultrasonic vibrations. It is proposed to influence particles with nonlinear im pulses of pulse durations from 2 microseconds or more, in the ranges of ULTRASONIC impact intensities averaged over a period of time, up to 0.06 W / cm2 and limited by the design features of radiation sources (the average sound pressure level in the far field does not exceed 150 dB). On the basis of mathematical modeling, it is shown that the area of the effective cross-section of the collision of particles increases under the impulse action. This makes it possible to increase the coagulation efficiency at least 5 times more than the sinusoidal effect.
- Index terms: gas cleaning, ultrasound, coagulation, vibrations, emitter.
