脉冲—旋风组合气流干燥系统研究

Study on Development of Air Convection Drying System in Combination of Pulse Tube with Cyclone Drier

通过对脉冲气流干燥器与旋风气流干燥器特点的分析,结合工厂工艺要求,研制了脉冲—旋风组合气流干燥装置。实践表明,这种组合干燥系统可充分利用两种干燥器的特点,具有传热,传质效果好,热效率高,适应能力强的特点。适用于初始物料水分较高(>10%w),潮湿状态有一定粘结性的松散粉粒的干燥。该组合干燥装置已经用于粉状谷氨酸钠不同品种物料的干燥。

The feature of pulse tube drier and cyclone drier was analyzed. Accoding to the demand of production,a new drier system to combine pulse air convection drier with cyclone drier was developed. Practice proved that the new system possess showed many advantages over either of the two driers used alone. The new drying system possessed high mass transfer efficency and heat efficency. It fitted to dry every single powder and grain material of low stiky matter. It has been used for drying monosodium glutamate powder in factory.
