This utility model discloses a device for single-meter and mixed-meter measurement of denitrification flue gas. It includes multiple sets of sampling pipelines installed on the denitrification flue. These pipelines are arranged sequentially along the flue gas flow direction within the flue and are equally spaced. All pipelines are connected to the same sample gas chamber. A fan is installed on the top wall of the sample gas chamber's inner cavity. The sample gas chamber is connected to a connecting pipe that communicates with its inner cavity, and a NOx analyzer is connected through this connecting pipe. This utility model utilizes multiple sets of sampling pipelines to extract flue gas from different locations within the denitrification flue and, in conjunction with the NOx analyzer, achieves multi-point single-meter monitoring, reducing the cost of multi-point NOx concentration measurement. Furthermore, the equally spaced sampling pipelines facilitate the acquisition of NOx concentration variations within the area. The sample gas chamber and fan ensure thorough mixing of multiple flue gas streams, meeting the requirements for mixed-meter measurement.
