    Abstract: Fine particles of dust and other pollutants in gas streams entering a duct (10) are agglomerated to form larger particles which are more easily filtered in downstream processing. Particles in successive portions of the gas stream are charged by an AC ionizer (14) with opposite polarity, and the gas stream is introduced into an Evase portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, aided by vibrators (13), leading to agglomeration of oppositely-charged particles.

    Abstract: Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species. The invention has particular application in air pollution control, by promoting agglomeration of fine pollutant particles in air streams into larger particles to thereby facilitate their subsequent removal from the air streams.

    Abstract: An aerodynamic agglomerator ( 10 ) promotes mixing and agglomeration of pollutant particles in a gas stream, to facilitate the subsequent removal of the particles from the gas stream. The agglomerator ( 10 ) is mounted in a duct ( 11 ) through which the gas stream flows. The agglomerator ( 10 ) comprises a plurality of parallel plates ( 12 ) which extend in the overall direction of flow of the gas stream, and are spaced transversely across the width of the duct ( 11 ) to divide the duct into multiple parallel passages. The duct ( 11 ) is configured and/or has formations therein for creating large scale turbulence in the gas stream upstream of the passages. A vane assembly ( 13 ) is provided in each passage for generating a zone of small scale turbulence of such size and/or intensity that the pollutant particles are entrained in the turbulence. Each vane assembly ( 13 ) is located centrally relative to its respective passage and comprises a plurality of sharp-edged vanes ( 15 ) spaced successively in the overall direction of flow of the gas stream. The large scale turbulence in the substreams causes each substream to pass through the zone of small scale turbulence in its respective passage so that particles therein are subjected to the small scale turbulence.
