西藏DG水电站环保智能排水系统设计

Design of Environmental Friendly and Intelligent Drainage System of DG Hydropower Plants in Tibet

西藏地区水电站所处环境的特殊性,导致其设计过程远远复杂于内地,而排水系统作为厂房内重要的辅助设备系统,其成功与否影响着电站的安全稳定运行。文章介绍了西藏DG水电站厂内排水系统的设计,并简述了设备布置的特点。该电站排水系统将无油渗漏排水系统和含油污水排水系统分开设置,响应了环保需求;同时,通过设置防冻排水管以及管网在线监测系统,保证了设备和管路的安全。该电站排水系统设计充分结合了当地气候环境的特点,配置安全可靠合理,可为同类型电站的选型设计提供参考。

The environment particularity of hydropower stations in Tibet makes the design process far more complicated than that in the inland.Besides,as an important auxiliary equipment system in the plant,the drainage system affects the safe and stable operation of the power station.This paper introduces the design of the drainage system of the ground powerhouse of Tibet DG Hydropower Station,and briefly describes the characteristics of equipment layout.The drainage system of the power station separates the oil-free drainage system and the oily sewage drainage system to satisfy the needs of environmental protection.At the same time,the installation of freeze-proofing drain pipes and an online monitoring system for the pipe network ensure the safety of equipment and pipelines.The design of the drainage system fully incorporates the characteristics of the local climate environment,which can provide a reference for the selection and design of the same type of power stations.
