Abstract:

There are eleven counter-current cooling towers in the circulating system of the second largest chemical fertilizer equipment in Ningxia Petrochemical Co.Reducer+transmission shaft are used for electrically driving their wind turbines.The matched electric motor power is 200 kW.To decrease the energy consumption in the production process and reduce costs, energy-saving modification for the cooling towers has been carried out by the company.For example, hydroturbine has been used for replacing the electric motor.Furthermore, its feasibility has theoretically been discussed, and modification has been carried out combining with the actual site situation, and pretty good results have been obtained.

Key words: energy saving, hydroturbine, cooling tower, circulating water treatment
