Abstract

The solar energy is the language of this age. It is renewable, clean and almost without cost. This research is focusing on utilizing of renewable energy in air purification process. As known, our environment is full with industrial waste gases, such as SOX, NOx, COX, CH4, H2S etc. To reduce percentage concentration of these gases, solar energy is used to generate a convection stream within a metal black column. Polluted air consists of industrial waste gases, while passing through the column, it will contact with baffles of an activated carbon plates, fixed horizontally to increase the contact area with gases. The activated carbon is a common adsorbent with tremendous adsorption capability. So it will remove waste gases from polluted air. The three-dimensional steady-state continuity, Navier-Stokes, energy, radiation, natural convection, species transport for CO2 physical adsorption and multiphase Eulerian-granular model equations are solved under turbulent condition, using the commercially available Computational Fluid Dynamics software Fluent. The quality of the solutions obtained from these simulations is largely within the acceptable range proving that Computational Fluid Dynamics is an effective tool for predicting the behavior and performance of a solar air filter.
