【摘要】：核电站除盐水分配系统设置有除盐水箱,存储除盐水生产线出水,调节下游用水波动。水箱与大气相通,无密封措施,受空气中CO_2等物质影响,运行一段时间后,水箱内pH降低,电导率增大。分析几种除盐水箱密封技术,探讨适用于核电站除盐水分配系统水箱的密封技术方法。
[Abstract]:The desalted water distribution system of nuclear power station is provided with desalination tank, which stores the effluent of desalting production line and regulates the fluctuation of downstream water. The water tank communicates with the atmosphere and has no sealing measures, which is influenced by CO_2 and other substances in the air. After running for a period of time, the pH in the tank decreases and the electrical conductivity increases. Several sealing techniques of desalted water tank are analyzed, and the sealing technology suitable for the water tank of desalted water distribution system in nuclear power station is discussed.
