Wet flue gas desulfurization and denitrification project refers to the removal of sulfur dioxide and nitrogen oxides in flue gas by wet method. The main principle is to use chemical reactions to convert these pollutants into substances that can be easily treated, so as to achieve the purpose of purifying flue gases.
Specifically, wet desulfurization uses alkaline absorbents (such as limestone, soda ash, etc.) to react with sulfur dioxide in flue gas to produce compounds such as magnesium sulfate or calcium sulfate. Wet denitrification uses reducing agents (such as ammonia, urea, etc.) to reduce nitrogen oxides in flue gas into nitrogen or ammonia.
Wet flue gas desulfurization and denitrification project has the following advantages:
Good removal effect: The wet desulfurization and denitrification process can efficiently remove SO2 and NOx in the flue gas to achieve a more thorough purification effect.
Wide adaptability: Wet desulfurization and denitrification technology is suitable for different types of fuels and working conditions, and can be adapted and operated under different treatment conditions.
Utilizable products: Wet desulfurization products contain sulfur dioxide and nitride, which can be reused to produce sulfuric acid, ammonia, phosphate fertilizer and other raw materials, which is of economic significance.
Anti-pollution performance: The wet desulfurization and denitrification system adopts a high-precision spray tower or reactor, which has strong adaptability to different flue gas conditions, can filter impurities in the flue gas, and prevent soft agglomeration and blockage, condensation crystallization and corrosion.
Strong controllability: The wet desulfurization and denitrification system can accurately control the key parameters in the process of desulfurization and denitrification, such as temperature, pH value, absorption liquid concentration and other parameters, which can ensure the effective progress and stability of the reaction.
However, wet desulfurization and denitrification also have some disadvantages, such as high energy consumption requirements and the wastewater generated by the reaction needs to be treated.
