Description

technical field [0001] The invention relates to the field of desulfurization and denitrification devices, in particular to a boiler flue gas desulfurization and denitrification device. Background technique [0002] A boiler is a kind of energy converter, which is a device that uses the heat energy released by fuel combustion or other heat energy to heat working medium water or other fluids to a certain parameter. When the boiler is in use, a large amount of polluting gas will be generated. Therefore, desulfurization and denitrification are one of the important technical measures to prevent and control air pollution. The traditional denitrification methods are SCNR method and SCR method. The contact time between flue gas and reducing agent in the ordinary denitrification process Shorter, the reaction time is not sufficient, and the same problem exists in the desulfurization process, so now a boiler flue gas desulfurization and denitrification device is needed to help solve th...
