AI Technical Summary

Technical Problem

The prior art has problems of insufficient accuracy and reliability when detecting dissolved hydrogen content in water, which makes it difficult to effectively monitor hydrogen leakage in the generator stator cooling water system.

Method used

The hydrogen in water detection device with dual quantitative tubes and two-way injection detection is used to reduce the dissolved hydrogen content in water through one detection branch with degassing function, and accurately detect the dissolved hydrogen background in water; the other directly detects the dissolved hydrogen content in water, and obtains the final result by calculating the deduction of the background, eliminating the impact of different water quality.

Benefits of technology

It improves the accuracy and reliability of the detection of dissolved hydrogen content in water, can effectively eliminate water quality interference, make the detection data of different units and the same unit comparable at different periods, and enhances the monitoring ability of hydrogen leakage in the fixed cold water system.
