OPTIMIZATION ON ADSORBER STRUCTURES FOR ASPHALT FUME FROM ALUMINUM INDUSTRIES USING CFD

Asphalt fume from Aluminum Industries is one of pollutants, which must be decontaminated in theventilation systems. In this paper, two feasible structures of adsorbers were designed: the venturi-typeadsorber with the small-diameter throat pipe and that with the flow-guiding cone. Then these two kindsof adsorbers were optimized according to the factors which influence the diffusion of the adsorbentparticles.
