AI Technical Summary

⚠Technical Problem

Existing odorant monitoring technologies rely on complex instruments that are bulky, cumbersome to operate, and time-consuming and labor-intensive manual sampling and laboratory analysis, which cannot achieve real-time monitoring and thus cannot meet the online real-time detection requirements for odorant concentration in natural gas pipelines.

⚗Method used

A natural gas odorant detection device was designed. It operates autonomously using the power of the natural gas pipeline. By switching the gas path through the control valve and combining the linkage of the impeller, filter and detection components, the sample gas can be autonomously diverted, filtered and automatically detected. The filter is cleaned by magnetic vibration and the detector is automatically calibrated, forming a closed-loop detection system.

🎯Benefits of technology

It enables online real-time detection of natural gas odorant concentration, reduces equipment costs, avoids explosion-proof safety hazards, extends the service life of the device, improves detection accuracy and efficiency, and reduces manual maintenance costs.
