竖井旋流内消能技术在辽宁恒仁水电站的应用

Applying of Shaft Rotational Flow Internal Energy-dissipation Technology to Liaoning Hengren Hydropower Station

竖井旋流消能是一种新型水力消能技术,能够克服大型水电站导流洞常出现的雾化、空蚀破坏、水力冲蚀等有害现象,也可作为维持环境生态流量的有利措施应用于水电站工程建设中。本文结合辽宁恒仁水电站竖井旋流内消能工的设计施工实践与经验,对该技术应用的布置方案、设计要素、参数选择、水力计算等进行简要分析研究。

Shaft rotational flow energy dissipation is a new waterpower energy dissipation technology that helps overcome pernicious phenomenon such as pulverization,cavitation erosion,waterpower washout and so forth that usually show up in diversion tunnel of large-scaled hydropower stations. It can also applied to construction of hydropower projects as conducive measures to maintain environmental and ecological flow. By combining with designing and construction practice and experience of shaft rotational flow internal energy dissipater,this article carries out brief analysis and research on layout plan,designing factors,paramater selection,hydraulic calculation and so forth of application of this technology.
