Measures and Development of Summer Operation of Directed Air Cooling Unit |
| |
| Abstract: | Directed air cooling unit is built widely in north area of China because of saving water.The main problems of directed air cooling unit in summer operation were analyzed,and corresponding measures were also given.The results show that high air inlet temperature,strong wind,tube dirty and high water temperature of vacuum pump are main factors influencing back pressure.Installing spraying system,extending windbreak wall and installing guide vane or windbreak net are important measures to insure safe and economic operation of directed air cooling unit in summer season. |
