Air-Carton Packaging Waste Flow Dynamics in a Conical Spouted Bed

AbstractCurrently, the generation of modern solid waste has caused large environmental impact. Because of the high addedvalue components, the carton packaging highlights among the wastes generated in large urban areas. The manufacture of tiles (or plates) and the pyrolysis are the main routes for the recycling of these wastes. In literature, the conical spouted bed has been pointed out as a promising air-solid contact system for processing the pyrolysis. Thus, this research aims to analyze the air-carton packaging waste flow dynamics in a conical spouted bed. The flow behavior of air-waste was experimentally investigated by analyzing data of bed pressure drop, air velocity and fountain height. Moreover, the simulation of operating conditions in the conical spouted bed was conducted using the computational fluid dynamics (CFD). It was found that particles of carton packaging in a shaped of disks do not achieve the spouting regime. However, for beds with mixtures composed of polyethylene and carton disks(5 and 10% carton weight), the spouting regimes wereattained.Furthermore, the simulations in ANSYS FLUENT software using the Eulerian Granular Multiphase model showed good agreement with experimental data
