折流移动床干燥行为研究

Drying Behavior in the Z-Path Moving Bed Drier

在折流移动床流动特性研究的基础上 ,以小米为干燥对象 ,对此新型反应器在干燥中的应用进行了研究 ,实验观察并分析了各种操作条件对干燥效果的影响。结果表明 ,折流移动床完全可以用于较大颗粒的干燥 ,并且具有产物均匀且易于调控的优点 ,同时多层床的实现 ,提高了干燥过程中热能的利用率 ,装置低压损的特性减少了动力消耗。同时建立了干燥模型 ,对该过程进行了模拟 。

Based on the flowing characteristic of gas and particle in the Z-path moving bed, theoretical analysis and experiment of drying process in the Z-path moving bed have been conducted. Millet is adopted as drying material. Results show that Z-path moving bed can be used to dry granular material. The proposed process has the advantages of high quality product, energy saving and easy control.And mathematical simulation was well corresponding with the experiment result.
