摘要
通过对砖坯干燥传热传质过程的分析 ,建立了砖坯干燥的准稳态二维数学模型 .在此基础上通过数值计算 ,得到了砖坯温度上升和水分蒸发的曲线 .在不同的瓷砖生产厂家实际所测量的数据验证了这一数学模型的有效性 .对比了不同位置的温度上升和蒸发速率变化 ,并简要分析了影响干燥时间的主要因素 .
The quasi steady two dimension model of brick drying is established by the analysis of heat and mass transfer of brick drying Numerical calculation is carried out and the figures of temperature rise and water evaporation are obtained The model is verified by the data from different tile factories.The temperature rise and water evaporation rates are compared for different positions of brick dried and the main factors that affect the drying time are analyzed
