印染污泥薄层干燥动力学分析
, PP. 62-66
Keywords: 印染污泥,薄层干燥,干燥模型,有效扩散系数,活化能
Abstract:
通过印染污泥薄层干燥试验，研究干燥温度和污泥厚度对印染污泥干燥特性的影响，并与造纸污泥进行对比，比较不同薄层干燥数值模拟模型，最终选用modifiedpage模型描述印染污泥薄层干燥过程，求出印染污泥的有效扩散系数和活化能。结果表明，干燥温度越高、污泥厚度越薄，污泥干燥速率越大；不同污泥干燥特性存在明显差异，印染污泥厚度对干燥速率的影响程度比造纸污泥大；当干燥温度为140~200℃时，印染污泥的有效扩散系数为2.9667×10－8~8.3888×10－8m2/s；印染污泥水分扩散的活化能为3.88kj/mol，比造纸污泥低5.555kj/mol。
