Principle of waste heat recovery and utilization: waste heat recovery refers to the recovery and utilization of waste heat generated in industrial processes. The main technologies include heat exchange technology, heat energy conversion technology and waste heat refrigeration and heating technology. Waste heat refers to the sensible heat and latent heat that have not been reasonably utilized in the original design of industrial energy-consuming devices that have been put into operation due to the limitations of history, technology and concepts. There are many ways to recover waste heat. Generally speaking, the comprehensive utilization of waste heat is the best, followed by direct utilization and indirect utilization (such as waste heat power generation). Comprehensive utilization means that according to the quality of waste heat, high-quality waste heat is used in production process or waste heat power generation in different temperature order; Medium (120 degrees-160 degrees) can use ammonia absorption refrigeration equipment to generate cold energy of -30 degrees to 5 degrees for air conditioning or industrial use; Low temperature can be used for heating or absorption heat pump to increase the heat or temperature for production and life. Waste heat recovery equipment is not mechanical equipment.
heat exchanger
Waste gas waste heat recovery device is to extract the inlet temperature of fresh air needed by industrial equipment to heat the equipment, thus reducing the exhaust temperature and saving heat energy. Heat setting machine, coating machine and other industrial equipment. There are many ways to recover waste heat.
