本文运用萘升华方法,通过实验测定了流化过程中,多层流化床内萘蒸汽的传质浓度分布,得到萘蒸汽浓度与进气量、颗粒进料量等因旁之间的关系式。为进一步研究多层流化床内气体介质与固体颗粒之间的对流换热系数打下基础。
In this paper, the naphthalene sublimation method was used to determine the mass concentration distribution of naphthalene in the fluidized bed during the fluidization process. The relationship between naphtha vapor concentration, . This study lays the foundation for further study on the convective heat transfer coefficient between gaseous medium and solid particles in multi-layer fluidized bed.
