涡环流排沙在阜康白杨河电站中的应用

Desilting Application by Eddy Current in Baiyang River Hydropower Station, Fukang

涡环流排沙技术是在漏斗排沙的基础上提出的又一新技术。该技术采用不对称结构设计来适应不对称流态 ,在涡内设置了稳定环形成内涡与外环 ,内涡的水流由稳定环的底部从外环进入 ,增加了自由涡与外环的底部流速 ,对泥沙的运移十分有利。该技术在阜康市白杨电站运行 5年来未出现异常 ,通过进一步研究完善后 。

This technique of desilting by eddy current is a new one based on funnel-shape desilting.It has applied asymmetrical structure design for asymmetrical current. Steady loop installed separates eddy current and circulating current. Water from instrument flows from outside loop through the bottom of steady loop, which will add water velocity of the bottom of steady loop resulting in conveying silt quickly. The technique has been practised for five years in Baiyang River Hydropower Station, Fukang. Good perspective will come after further research.
