Abstract：Based on the response surface method,the drying temperature of the drying room,the stopping time of the conveyor belt and the working frequency of the slicer during the drying process of the sludge low temperature heat pump were optimized and analyzed.Through the experimental design and data analysis,the response surface model and the prediction mathematical model of the dehumidification energy consumption ratio were established.The results show that the dehumidification energy consumption ratio reaches the maximum value of 1.833 kg/kWh under the conditions of drying room temperature 55℃,conveyor belt stopping time 5 min and strip cutter working frequency 41.17 Hz.The drying experiment was repeated,and the average relative error between the experimental results and the predicted value was only 2.2%,which met the requirement of<10.0%.The model had high prediction accuracy and could well predict the dehumidification energy consumption ratio of low-temperature sludge drying.
