针对我国北方地区发电厂中冷却水塔冬季防冻问题,提出了循环冷却水塔快速喷雾结冰技术.通过与悬挂挡风板冷却塔的对比,论证了快速喷雾结冰技术在优化调节循环水温度及循环冷却水塔防寒防冻方面的明显优势.结果表明:采用快速喷雾结冰技术能够使冷却水塔在严寒季节或天气情况突变时安全运行,可以使机组循环水温度随着环境温度高低和机组负荷大小而自动调整,以达到最佳值,从而提高了机组的经济性.
Aiming at the problem of winter frost prevention in cooling towers of power plants in northern China, a rapid spray icing technology for circulating cooling towers is proposed.Through the comparison with suspension windshield cooling towers, it is demonstrated that rapid spray icing technology can optimize circulating water temperature and circulation The results show that the rapid spraying icing technology can make the cooling tower operate safely in the severe cold season or when the weather conditions suddenly change, which can make the circulating water temperature of the unit automatically with the ambient temperature and unit load Adjust to achieve the best value, thus improving the economy of the unit.
