[0002] As my country pays more and more attention to environmental protection, flue gas pollution is a top priority. Therefore, it is necessary to sample the flue gas and then determine whether it meets the emission standards. The flue gas sampling tube is a device used for flue gas sampling. The traditional sampling tube is made of a single pipe wrapped in a protective cover.

[0003] The existing flue gas sampling tubes have certain drawbacks when in use. The existing sampling tubes do not have an adsorption function, which causes the pollutants in the flue gas to be partially or completely adsorbed on the tube wall, resulting in low results or large deviations in the analysis results, affecting the accuracy of the flue gas analysis. Secondly, the traditional sampling tubes have a single structure and are easily burned by high temperature, causing injuries to workers.
