AI Technical Summary
The detection of flue gas from high-altitude flue gas outlets is inaccurate due to pollutants adhering to the flue gas duct, especially when standard gas is introduced at the top, which is difficult to solve effectively with existing technology.
The system employs a structural design that includes a chromatograph, flue gas duct, upper and lower phosphoric acid storage cylinders, phosphoric acid guide wire, and delivery pump. The phosphoric acid guide wire is used to titrate phosphoric acid from the upper storage cylinder to the lower storage cylinder. The flue gas is acidified by passing through the inner wall of the polytetrafluoroethylene-coated flue gas duct to prevent condensation.
This effectively prevents flue gas from condensing on the inner wall of the pipeline, ensuring accurate calibration of the chromatograph and improving detection precision.
