The method for increasing the separation efficiency of particles smaller than 2.5 micrometers by combined ultrasonic agglomeration and swirling flow technique is proposed in article. creates areas with an increased concentration on outer radius vortex. exposure these leads to more efficient formation agglomerates many times larger original particles. resulting are easily separated from gas flow. design agglomerator was developed. vortex velocity determined, at which increases average particle size d32 = micrometer 4.5 times. a rectilinear can increase no 1.6 comparison. compared inertial clearing cyclone. It found that allows cleaning 46% 85%
