    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 translation: 进入管道（10）的气流中的灰尘和其他污染物的微粒聚集形成较大的颗粒，其在下游处理中更容易过滤。 气流的连续部分中的颗粒由具有相反极性的AC电离器（14）充电，并将气流引入Evase部分（12）以使其减慢。 不同尺寸的颗粒具有差的减速度，因此通常由振动器（13）辅助的流动方向混合，导致相反带电的颗粒的聚集。

    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.
