Performance Analysis of Boiling Drying Granulator Cutting Spraying Assisted Wind Field

Abstract

Abstract Through computational fluid dynamics (CFD) analysis, the research focused on the influence of fish-scale hole structure and porosity on the airflow uniformity within a cutting and spraying form fluidized bed drying granulator. By optimizing the airflow distribution through simulation calculations, the overall performance of the granulator was improved, leading to enhanced drying efficiency and reduced energy consumption. Furthermore, a comprehensive understanding of the complex airflow patterns and turbulence characteristics within the granulator was gained, facilitating the identification of factors impacting airflow uniformity, such as the structural design and opening rates of the fish-scale hole structure. This knowledge contributed to the development of effective process control and optimization strategies. The research findings demonstrated that the best internal airflow uniformity was achieved when the fish-scale holes had a width of 21mm, a hole height of 3mm, and an overall porosity of 8.4%, or a width of 24mm, a hole height of 2.5mm, and an overall porosity of 8.0%. These results provide guidance for achieving better product outcomes in industrial applications.
