对撞流干燥散粒状物料的试验研究

Experimental Study on Impinging Stream Drying of Particulate Materials

在同轴对撞流干燥试验台上进行了对撞距离、对撞室体积、对撞室形状和不同物料的干燥试验研究 ,得出了一些重要的对撞流干燥的规律。试验结果表明 ,对撞距离大 ,干燥效果好 ;对撞室体积大 ,干燥效果好 ;长方形比竖直圆筒形对撞室的干燥效果好 ;

Experimental study on the influence of impinging distances , the volume and the form of the impinging chamber and different particulate materials on the process of impinging stream drying (ISD) was performed on an experimental coaxial impinging stream dryer, and a number of important conclusions were drawn. The test results showed that the longer the impinging distance is, the better the effect of drying is; and the larger the volume of the impinging chamber is, the better the effect of drying is. The effect of drying of the rectangular chamber was better than that of the cylindrical one. The experimental results also indicated that the impinging stream drying was more suitable to the powdered materials of high moisture content.
