Heating of drying medium: In the drying process of chemical materials, it is necessary to heat the drying medium (such as air, nitrogen, etc.) to a certain temperature to improve the drying efficiency. Heat pump heat exchangers can elevate the temperature of thermal energy or industrial waste heat in the environment and use it to heat drying media. For example, when drying pesticide intermediates, a heat pump heat exchanger is used to heat the air and raise the air temperature to 60-80 ℃, providing the required heat for the drying process. Compared with traditional electric or gas heating methods, it can significantly reduce the drying cost.
Recycling of waste heat from drying exhaust gas: The exhaust gas emitted during the drying process of chemical materials usually contains a certain amount of heat and moisture. If directly discharged, it will cause energy waste and environmental pollution. A heat pump heat exchanger can cool dry exhaust gas, recover its heat, and condense the moisture in the exhaust gas, achieving the goal of waste heat recovery and energy conservation and emission reduction. The recovered heat can be used to preheat fresh drying media or other processes, improving energy utilization efficiency.
