AI Technical Summary

Technical Problem

Existing nuclear power plant liquid-to-gas conversion technology lacks real-time online monitoring methods, making it impossible to identify and prevent excessive particle size of gaseous effluents, posing an environmental safety hazard of radioactive material deposition and accumulation.

Method used

A laser scattering particle size analyzer is used to monitor the particle group in the air duct in real time. A preset target value is set, an alarm signal is generated, and the parameters of the fan and water distribution pump are adjusted to ensure that the particle size of the gaseous effluent is discharged within a safe range.

Benefits of technology

It enables real-time online monitoring of gaseous effluents from the conversion of liquid to gas in nuclear power plants, avoiding excessive emissions of large-diameter particulate matter and ensuring environmental safety.
