چکیده
The hydrodynamic behaviors of refined sugar bed with a continuous gas stream and a horizontal pulsed gas in a gas-particles bubbling fluidized bed were simulated by the 2D Two Fluid Model. The effect of pulse frequency on the hydrodynamics of the gas and particles was also analyzed. The results show that the porosity of the bed and the size of the bubbles caused by the pulsed gas were greater than those of the continuous fluidization. The simulation results also determined that the average velocity of the gas flow through the distribution grid is greater than 0.94 m.s-1 and the pulse frequency changes between 0.5 Hz and 1.5 Hz, which is suitable for pulsed gas fluidization for refined sugar products. In this range, the superficial velocity reaches an average value of 0.67 m.s-1, fluctuating between 0.35 m.s-1 and 0.9 m.s-1, the bed porosity varies within this range 0.25 - 0.59, and the pressure drop across the bed ranges from 300 - 900 Pa. The gas-particles bubbling fluidized bed system with pulsed gas flow enhances the mixing of particles and gases while reducing gas flow compared to the conventional continuous fluidized bed system.
