某炼油厂冷却塔工艺改造与运行效果分析

Technological upgrading and operation effects analysis of the cooling tower in refinery

某炼油厂原有常规填料冷却塔存在风阻大、热性能差、运行费用高、冷却水浓缩倍数高等问题,需行优化改造。将原有冷却塔改造成无填料喷雾冷却塔,同时改变布水方式并更换涡流式风机。实践表明,改造后降温效果理想,节能、节电效果明显。

There were some questions such as the bigger wind resistance, poor energetic efficiency, high operation cost, and high cycle of concentration in cooling water in conventional padding cooling tower of some refinery, which needed optimizing upgrading reconstruction to change the old cooling tower into no-padding spraying cooling tower, change water distribution way and vortex blower. The practical operation showed that, after reconstruction, the temperature reduction, energy-saving, and electric-saving effects were satisfying.
