Claim 0:
1. An aggregating device for separation and/or purification of aerosols and solid material particles from gases, comprising:
(a) an aggregating tube having an inlet at a front end, an outlet at a rear end, and a round cross section, the tube extending concentrically around an axis, said aggregating tube forming aggregated solid material particles;
(b) a conveying means conveying an aerosol in a conveying direction into the front end of the tube, wherein the aerosol comprises the solid material particles and gases;
(c) a plurality of mutually corresponding exciters arranged opposite to each other and located within the aggregating tube, each exciter comprising a piezoelectric element, each pair of mutually corresponding exciters generating a standing acoustic sound wave at a right angle to the conveying direction,
wherein:
(i) the solid material particles move towards a plurality of pressure nodes by a force of the standing acoustic sound waves and form aggregated solid material particles in a space around the plurality of pressure nodes; and
(ii) the gases move toward a plurality of pressure antinodes by the force of the standing acoustic waves;

(d) a filter separating the aggregated solid material particles from the gases; and
(e) an ultra-violet (UV) radiator fixedly mounted relative to the container heating the aggregated solid material particles in the aggregating tube;, wherein:
each pair of mutually corresponding exciters generates a standing acoustic sound wave having a multiple pressure nodes and multiple pressure antinodes between the pair of mutually corresponding exciters; and
a particle passing between the pair of mutually corresponding exciters moves toward one of the multiple pressure nodes.
