| 摘 要： | 针对水电工程中尾水洞长度对无压尾水洞引风技术应用的限制,提出了受控条件下无压尾水洞引风技术,即采用低温尾水对无压尾水洞处理后的空气进行二次喷淋处理,以实现对引风参数的控制.工程应用表明:在无压尾水洞长度有限的水电工程中,应用该技术可有效突破尾水洞长度对无压尾水洞引风技术应用的限制,拓展其应用范围,实现对具有无压尾水洞的水电站通风空调系统的"无冷机"运行.

| Abstract: | In view of the condition that the tailrace tunnel ventilating application is limited by the length of tunnel in hydropower engineering,an air-parameter control technology with a finite tailrace tunnel length is presented.The technology utilizes the low temperature water to handle the tunnel outlet air by spraying.The performances of the air control technology in an engineering application are analyzed,and the results indicate that the combined technology can break through the limitation of the tunnel length... |
