Description

Technical Field

[0001] The utility model relates to the technical field of flue gas measurement, and particularly relates to a gas cell heating structure. Background Art

[0002] The on-line flue gas monitoring system is an important environmental monitoring system, which continuously monitors the pollutant concentration in flue gas emissions during industrial production processes. It can monitor the content of various harmful substances in flue gas in real time to ensure that the discharged flue gas meets national and local environmental protection standards.

[0003] In related prior art, the cold dry method gas detection system must ensure that the flue gas entering the analyzer is dry. If there is moisture, it will cause the value of the gas soluble in water to be lower than the actual value. The cold dry method gas detection system requires the gas to be kept dry before entering the analyzer, so the gas needs to be dried before entering the analyzer. The hot wet method gas detection system performs full-course tracing heating on the gas path and then directly measures the raw flue gas.

[0004] However, whether it is the cold dry method gas detection system or the hot wet method gas detection system, the heat treatment of flue gas in both methods is not ideal, resulting in distortion of the detected data of flue gas. For example, for the cold dry method gas detection system, after drying the flue gas, the water content in the flue gas is still relatively high. For the hot wet method gas detection system, it performs full-course tracing heating on the gas path through a tracing pipe, but the hot wet tracing heating temperature is often lower than the flue gas dew point temperature.
