Abstract

This study focused on the optimization of the structure of built-in vertical clapboard in the rapeseed fluidized bed dryer. Based on standard k-ε turbulence model and Euler two-fluid model, the number of region and the arrangement mode of clapboard was optimized through numerical simulation calculating software of Fluent. The results showed that the inhomogeneous three region clapboard was the best built-in vertical clapboard for rapeseed fluidized bed drying, enhancing the circulation of hot air, and reducing hot air accumulation in local areas. Finally, it realized the normal fluidization of gas-particle two-phase flow, and achieved the goal of uniform distribution of rapeseed particles in fluidized bed, without the groove flow and dead zone.
