AI Technical Summary

Technical Problem

The existing remote monitoring and fault diagnosis system for At-211 separation devices cannot promptly identify the retention risk caused by the coupling effect of temperature rise and carrier gas flow rate decrease, resulting in At-211 retention in the transmission channel and deposition on local walls, affecting the recovery rate.

Method used

By acquiring heating zone temperature, carrier gas flux, and pressure data during the separation cycle, sampling sections with positive temperature changes and negative flux changes are selected. The intensity of continuous retention trend and trajectory drift is calculated to generate a retention risk signal, and the heating input and carrier gas supply are adjusted to avoid retention.

Benefits of technology

It enables early identification and warning of potential retention risks, improves diagnostic accuracy and response speed, ensures that the equipment is in optimal operating condition, and avoids reduced separation efficiency due to retention.

Abstract

The application provides an At-211 separation device remote monitoring and fault diagnosis method and system, relates to the technical field of data processing, and the method comprises the following steps: according to periodic operation data, screening a sampling section with positive temperature change and reverse flux change as a candidate section, calculating the continuous retention trend intensity between each linkage unit, obtaining a retention induction coefficient, counting the linkage distribution range of the temperature change value and the flux change value of each time position in historical standard periodic data, determining whether each linkage unit falls into an operation reference domain at each time position, marking the linkage unit falling outside the operation reference domain as a deviation unit, counting the duration and deviation amplitude of the deviation unit, calculating the overall deviation degree of the operation track, obtaining a track drift intensity, determining the correction amplitude of heating input and carrier gas supply, and obtaining a correction instruction. The application can find the retention risk in the early separation process and generate a correction instruction, thereby avoiding At-211 deposition on the channel wall surface.
