Exhaust air heat recycle technology
Today, with rising energy costs and increasing requirements for exhaust emissions, Hyundai Drying is committed to saving energy costs for customers and improving energy efficiency. It continues to increase research and development and investment in spray drying energy recovery and utilization technology, and is internationally advanced The super heat-conducting recovery technology has been successfully applied to the exhaust gas emission recovery treatment process of spray drying equipment.
Take the spray drying equipment designed by Hyundai Drying for a food technology company in Taiwan as an example. Its exhaust gas discharge temperature is 100℃, and the exhaust air volume to be treated is 60000m3/h. If this exhaust heat recovery treatment device is not installed, a large amount of heat in the exhaust gas will be directly discharged into the atmosphere and be wasted. After the installation of the exhaust heat recovery treatment device, the company saved more than 2 million energy costs a year.
Energy saving calculation:
1. Dry bulb temperature according to outside air conditions: 30℃, outside air parameter 60000m3/h, calculated after recovery by super thermal conductivity recovery device, the final heat recovery per hour: Q1=440KW.
2. Calculate the total usage time based on 10 months of use, 24 hours a day, 25 days a month: 24×25×10=6000(h)
3. Save heat power Kw: 6000×440=2640000(Kw).
4. Calculated at 0.8 yuan per kilowatt of electricity, a total of 10 months of savings in transportation costs: 2640000×0.8=2112000.00 yuan
