摘要：

The hydrodynamics and performance of conical Spouted beds provided with different types of draft-tubes have been studied for the treatment of fine particles. Correlations for calculation of the minimum spouting velocity, operating pressure drop, and peak pressure drop have been developed as a function of dimensionless moduli that take into account the geometric factors, particle characteristics, and operating conditions. A statistical analysis of the data obtained Wowing a design of experiments shows that the height of the entrainment zone is highly significant in the nonporous draft-tubes, whereas the stagnant bed height is the Counterpart in the open-sided draft-tubes.
