Study on Engineering Application of Sodium Aerosol On-line Monitoring Device Based on Atomic Emission Spectroscopy
Sodium aerosol is a characteristic product produced when sodium leakage and sodium fire conditions occur in the sodium cold reactor,and the very early trace sodium aerosol monitoring in the air is of great significance to the related accident monitoring and accident disposal.In order to solve the blank problem of sodium aerosol online monitoring methods in the engineering application field,a sodium aerosol online monitoring device based on atomic emission spectroscopy was developed,and a detection system for engineering applications was designed based on the device.The system operation test under a small amount of real sodium aerosol environment and sodium leakage and sodium fire conditions was carried out.The results show that the sodium aerosol on-line monitoring system also has sampling and analysis and detection function for the sodium aerosol produced by real sodium combustion,the sampling design meets the needs of detector analysis,the monitoring system responds quickly and sensitively to sodium aerosol produced by sodium fire,has the ability to detect sodium leakage and sodium fire early,and realizes the system functions such as interlock alarm,and has the prospect and condition of engineering application.
