| description | The utility model discloses a flue gas SCR (Selective Catalytic Reduction) denitration device with a flue gas mixing and dust removing effect. An ammonia spraying device, a mixer, a pre-dedusting smoke pipe and a catalyst in the device are arranged in sequence; flue gas from the economizer is sprayed with ammonia (NH3) through an ammonia spraying device; under the state, the smoke velocity field is relatively uniform; fACILITATING HOMOGENEOUS DIFFUSION OF AMMONIA, on one hand, the flue gas can flow through a long path to reach the SCR denitration reactor; on the other hand, when the flue gas containing the ammonia passes through the mixer, the mixer further plays a role in reducing the temperature difference in the flue gas and strengthening the mixing of the ammonia and the flue gas, andthen the flue gas flows into the pre-dedusting flue gas pipe to be dedusted and then flows into the SCR denitration reactor. Practice proves that the arrangement mode can create a very uniform flow field condition for the SCR |
