新型环管喷射式干燥器的开发研究

摘要本文介绍了一种高效、节能的新型环管喷射干燥器的结构和操作原理。试验测定了不同送气量下三个喷嘴的流量分配、环管压降以及空气循环比。同时观察了颗粒在环管内的运行状态，经分析认为，两个主要的可调参数送气量和物料加入量的匹配是该干燥器正常运行的基本要求

Abstract： The newpattern,highefficient and energysaving looptube jet dryer was introduced in this paper.Distribution of the gas in three nozzlespressure drop of looptube dryer and the gas circulation ratio were measured at different gas volume rates.Besides,the moving status of the solid particles in looptube dryer was observed.It can be considered that the matching of two main adjustable operation parameters,the gas volume rate and the feedin solid,is the essential demand for the normal operation of the dryer.

Keywords： jet looptube dryer pressure drop circulation ratios
