摘要
本文研究二维(0.02×0.18×1.6m)与三维(φ0.15×2.0m)气液固流化床中以空气、氮气作为气相;水、酒精以及甘油溶液为液相;玻璃、塑料球作为固相,与气液速对相含率及其内构件的关系.
The author studies the correlation between the gas hold-up,liquid hold-up, bed porosity and the backmixing in two-dimensional(200×180×1600mm)and three-dimensional(150×2000mm)gas-liquid-solid fluidized beds.Gas-liquid- solid phases are represented by air;alcohol,glycerin;glass bead,plastic ball respectively.The author studies also the effect of gas-liquid velocity on phase hold-ups,bed porosity and backming.
