| 中文摘要 | Highly cohesive powders aggregate into wide-size-disuibution fluidized agglomerates in fast bed, which can severely aggravate the fluidizing quality. In order to reduce the agglomerate size of highly cohesive powders in riser, "floating internals" are added into riser to cause the breakage of agglomerates. Floating internals are floated by the two-phase flow of gas and cohesive particles in riser. However, the floating internals should not be entrained into particle return system, and, should not have any reaction with powders or gas. Therefore the fast fluidization of cohesive particles with floating internals is different from the circulating fluidization of fine-coarse particle mixtures. Experiments on floating internals were conducted in a glass riser of 3.25m in height and 0.075m I.D, and four kinds of cohesive powders and floating internals were involved. Experimental results showed that appropriate matching of floating internals with cohesive particles could effectively avoid the formation of over-large agglomerates in the riser. A model has also been developed to predict the largest agglomerate size which floating internals could break under certain operating conditions. Comparing with experimental values, the predicted results of the model are reasonable and acceptable. |
