摘要
研究了多孔板式内构件和桨叶式内构件对粘附性颗粒流态化的影响. 实验表明，多孔板式内构件对流化质量的改善不好，桨叶式内构件的效果良好但仍然存在缺陷. 通过结合二者优点开发的孔桨式内构件克服了桨叶式内构件的缺点，显著地改善了粘附性颗粒的流化质量.
To improve the fluidization quality of cohesive particles, the traditional perforated plate internals and the remiform internals as well as the new design of the perforated remiform internals were tested with cohesive γ- Al2O3 particles as the experimental material. The experimental results showed that the perforated plate internal was inefficient for improving fluidization quality of cohesive particles, the remiform internal was better than the former. The perforated-remiform internals combine the advantages of two traditional ones and was proved to be the best internals for using in cohesive particles.
