黄河多泥沙水电站技术供水防淤设计

Sedimentation prevention design of cooling water system for sediment-laden hydropower stations on the Yellow River

多泥沙水电站技术供水系统防淤有3种方式,最理想的是循环冷却供水。多泥沙中小型水电站技术供水系统应优先采用循环冷却供水。循环水池、循环冷却器和水泵是循环系统三要素,布置要合理,参数选择要留有裕量。重点介绍了循环冷却供水在技术供水系统中的重要性、应用和设计要点。

Three modes of sedimentation prevention can be used for cooling water system of sediment - laden hydropower stations, the most favorable one is circulating cooling water supply, which shall be firstly used for medium or small - sized, sediment - laden hydro- power stations. The circulating system is composed of circulating pool, circulating cooler and pump, which shall be arranged reasonably, with redundant parameters. The paper focuses on the importance of circulating cooling water supply in the cooling water system, application and design points.
