基于闭式热泵沸腾床干燥器流化特性与干燥的CPFD数值模拟
摘要
Abstract
The use of a closed heat pump fluidized bed dryer can achieve dehumidification,heating and recycling of the drying medium at the same time of efficient drying,and because of its relatively simple structure,it is easy to realize industrial scale-up.In order to further explore the fluidization characteristics and drying process of carrot particles in a closed heat pump fluidized bed dryer,the fluidization characteristics and drying process of carrot particles in a closed heat pump fluidized bed dryer were numerically simulated and analyzed based on Barracuda CPFD theory.By comparing the simulation data of CPFD and the experimental data under the same conditions,the Ganser drag model can accurately predict the fluidization characteristics and drying effect of carrot particles in the fluidized bed.This paper verifies that the numerical calculation method of CPFD can accurately predict the particle fluidization characteristics and drying process in the closed heat pump fluidized bed dryer,which has a very broad application prospect,and provides reliable guidance for the industrial scale-up study of the same type of fluidized bed dryer and the process design and parameter allocation of the new closed heat pump fluidized bed dryer.关键词
