摘要：A fluidized bed has the advantages of treating large flows, intensifying mass and heat transfer, and lowering costs. This study proposed a cyclonic fluidized bed packed with spherical activated carbon adsorbents for volatile organic compounds adsorption. The fluidization and self-rotation of the AC particles in a 25 mm cyclonic fluidized bed were studied with high-speed camera testing technology. The effects of the particle movement on the adsorption efficiency of toluene were also tested. The results show that most of the particles at the inlet side of the cyclonic fluidized bed were moving up when the inlet airflow rate was greater than 2.0 m 3 /h. The particles began to move in clusters when the relative packing height increased to a critical value of 0.57. Increasing the gas flow rate and the diameter and height of the core column will increase the self-rotation speed of the total particles. The maximum self-rotation speed of spherical adsorbents reached 1700 rad/s at the inlet flow rate of 2.5 m(3)/h. In the case of the same axial velocity of the gas phase in the upper space of the core column, increasing the particle self-rotation speed can slightly improve the adsorption efficiency. The maximum adsorption efficiency reached 99% when the inlet flow rate is 1.0 m(3)/h with relative packing height 0.65. (C) 2020 The Korean Society of Industrial and Engineering Chemistry.
