Device for improving flue gas mixing uniformity before denitration outlet CEMS (Continuous Emission Monitoring System) measuring point

The utility model discloses a device for improving mixing uniformity of flue gas in front of a denitration outlet CEMS (continuous emission monitoring system) measuring point, which comprises a flue gas mixing grid and a plurality of flue gas stirrers, the flue gas mixing grid is provided with a plurality of grids, the flue gas mixing grid is detachably mounted in a flue main body, and one flue gas stirrer is arranged in each grid. The utility model belongs to the technical field of environmental protection of coal-fired power plants, and aims to solve the problem of poor flue gas mixing uniformity before CEMS (continuous emission monitoring system) point measurement in the prior art. The flue has the technical effects that by arranging the flue gas mixing grid and the plurality of flue gas stirrers, flue gas can be fully mixed when flowing through the flue gas mixing grid and the flue gas stirrers, so that the concentration distribution of nitrogen oxides and ammonia contained in the flue gas in the flue mai
