Outline
In the paper, the design, research and development and performance verification of high-efficiency intelligent dry-wet cooling tower are carried out by taking the working conditions of high temperature, heavy dust and high load in the whole process of iron and steel as application scenarios as well as combining with plate-fin demisting heat exchange and intelligent collaborative control technology aiming at the pain points of high energy consumption and water consumption, poor adaptability of working conditions and high operation and maintenance costs for cooling system of ferrous metallurgy. The results showed that the automatic precise switch of dry model and wet model could be realized with the cooling tower, which was adapted to the cooling requirements of the whole process of iron and steel; annual average water-saving percentage could reach 22.3%; zero mist operation could be realized at the working condition of -10 ℃ and relative humidity of 70% so that such industrial problems as scaling, abrasion, drifting mist and higher energy consumption of traditional cooling tower could be effectively solved.
