When the river sand dryer is working, the river sand is transported into the dryer through the feeding device. In the dryer, the river sand is dried at high temperature by the hot air generated by the heat source. The hot air in the river sand dryer evaporates the water in the river sand through direct contact with the wet sand, and dries the wet sand to the required dry state. The dried river sand is discharged through the discharging device and becomes sand material suitable for different industrial fields. So what are the methods to improve the thermal efficiency of the river sand dryer?
1. Heat source optimization. Select a high-efficiency and stable heat source, such as gas, steam, etc., to improve energy utilization efficiency.
2. Heat recovery. Install a heat recovery device to recycle the high-temperature hot air in the hot air outlet and reduce energy waste.
3. Application of insulation materials. Use insulation materials to reduce heat loss and improve the thermal insulation performance of the river sand dryer equipment.
4. Drying process control. Through the intelligent control system, correctly control the drying temperature and time, avoid over-drying, and improve the efficiency of heat utilization.
5. Multi-stage drying. Divide the drying process of the river sand dryer into multiple stages, drying step by step to improve the thermal efficiency of the entire system.
6. Advanced heat transfer technology. Use advanced heat transfer technologies such as radiation heat transfer and convection heat transfer to improve the efficiency of heat energy transfer.
7. Utilization of waste heat. Utilize the waste heat generated by drying to preheat the feed or other links that require heat energy to reduce energy consumption.
8. Heat exchanger optimization. Design a reasonable heat exchange system, optimize the structure and layout of the heat exchanger, and improve the heat transfer efficiency.
