【摘要】 介绍了酞菁蓝干燥的特殊性及现有国内外干燥工艺,提出了将旋转导热干燥与旋转闪蒸干燥结合而成的组合干燥,若选择适当的工艺条件,可以用于酞菁蓝的干燥,并可替代惰性气体循环的干燥工艺。组合干燥热效率高,可达62.5%,是旋转闪蒸干燥的1.3倍。节能效果显著。组合干燥运行成本低,每吨干燥成本分别比旋转闪蒸干燥及惰性气体循环干燥低220元、710元,社会效益也十分显著。更多还原

【Abstract】 This paper analyzes the unique characteristics of drying of Phthalo Blue,introduces its present drying technique,presents a new drying technique combining spin-conduct drying and spin-flash drying,which can be used for drying of Phthalo Blue and substitute inert gas circulation drying under proper technical conditions.The result shows that thermal efficiency of the combined drying is high up to 62.5%,and 1.3 times as large as spin-flash drying alone,the operation cost of the combined drying is 220 yuan and 710 yuan lower than spin-flash drier and inert gas circulation drier respectively for drying of1 ton of Phthalo Blue.So,the energy saving and social efficiency of the combined drying technique is remarkable.更多还原
