TECHNICAL FIELD

[0001] The utility model relates to the field of flue gas desulfurization and denitrification equipment, in particular to a flue gas desulfurization and denitrification feeding device. BACKGROUND

[0002] Flue gas desulfurization and denitrification is a process for treating sulfur dioxide and nitrogen oxides in flue gas emitted in industrial fields such as coal-fired power plants. Common flue gas desulfurization methods include wet desulfurization and dry desulfurization. Wet desulfurization mainly absorbs and reacts through spraying lime milk or gypsum slurry to convert sulfur dioxide into sulfate, thereby achieving the purpose of reducing its emission. The application of flue gas desulfurization and denitrification technology can significantly reduce the emission of atmospheric pollutants and reduce the harm to the environment and human body. These technologies are widely used in the industrial field and have greatly improved the air quality and environmental protection situation. In common flue gas treatment devices, lime solution is used for desulfurization treatment, but the existing lime water for spraying is not completely dissolved in water, resulting in particle deposition in the configured lime solution, and the solution concentration gradually decreases over time, leading to a decrease in desulfurization effect.
