Description

Technical Field

[0001] The invention relates to the technical field of flue gas purification treatment, in particular to a flue gas desulfurization and denitrification purification treatment packed tower. Background Art

[0002] Flue gas desulfurization and denitrification treatment is to remove sulfur dioxide (SO 2 ), nitrogen oxides (NOx) and other harmful substances to reduce air pollution and protect the environment. Among them, the packed tower is an important equipment for the contact reaction between gas and liquid. It is widely used in wet desulfurization and denitrification systems. It mainly includes structural components such as tower body and packing. The flue gas enters from the bottom of the tower and meets the liquid (such as desulfurization liquid or denitrification liquid) in the tower. The liquid is evenly distributed to the packing layer from the top of the tower, and a thin film is formed through the packing layer to increase the contact area between gas and liquid. SO in the flue gas 2 Or NOx reacts chemically with the reactant in the liquid (such as lime slurry or ammonia water) to generate soluble compounds, thereby achieving the purpose of desulfurization and denitrification. The flue gas after the reaction is discharged from the top of the tower and usually contains lower concentrations of pollutants; When the packed tower performs desulfurization and denitrification operations on flue gas for a period of time, the internal packing will show scaling, corrosion, sinking and aging, resulting in a decrease in its physical and chemical properties. The packing needs to be replaced to prevent it from affecting the normal desulfurization and denitrification operations of the flue gas. However, traditional packing replacement requires disassembly and replacement one level at a time, and the packing bracket, liquid distributor, etc. must be disassembled one by one, which makes disassembly more troublesome and affects the overall use effect. For this reason, we propose a flue gas desulfurization and denitrification purification packed tower to solve the above problems. Summary of the invention
