摘    要：在不同的钛精矿粒径、流化床内料层高度和分布板开孔率下进行对比试验,探讨最小流化速度和流化质量的影响因子。结果表明,分布板开孔率和料层高度对最小流化速度影响不明显,最小流化速度随着粒径的增大而增大。在试验所选取的开孔率、料层高度、粒径大小下,均能达到较好的流化质量。

Abstract: The minimum velocity for gas to keep fluidization and fluidization quality for titanium concentrate were explored at different conditions that are titanium concentrate grain,layer height for reactant,and porosities on the distribution plate.It is shown that the porosities and layer height has little effect to the minimum velocity for gas to keep fluidization,but the minimum fluidization velocity increases with the increase of titanium concentrate grain.Additionally,under the very conditions for this experiment,the fluidization quality is satisfactory.
