METHOD AND APPARATUS FOR MIXING FLUIDS FOR PARTICLE AGGLOMERATION

摘要

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.
