The invention provides a flue gas desulfurization tower. Specifically, the flue gas desulfurization tower comprises a tower body, the lower part of the tower body is provided with a flue gas inlet, the top of the tower body is provided with a flue gas outlet, the tower body is provided with at least one spray layer and at least one sieve plate from top to bottom in order, and the spray layer and the sieve plate are arranged between the flue gas inlet and the flue gas outlet, wherein the spray layer is internally provided with spray elements communicated with an absorbent pipeline, and the spray elements include atomizing nozzles formed by an inorganic porous sintered material. Through the technical scheme, the flue gas desulfurization tower provided by the invention can achieve very good atomization effect under a low pressure, thereby improving the SO2 absorption efficiency, and achieving the effect of reducing the operation energy consumption of the flue gas desulfurization tower.
Description
technical field [0001] The invention relates to the field of chemical engineering, in particular to a flue gas desulfurization tower. Background technique [0002] Smoke generally refers to a mixture of gas and smoke. The operation of chemical equipment such as boilers, industrial furnaces, thermal power plants, coke ovens, cement plants, blast furnaces, open hearth furnaces, converters, electric furnaces and catalytic cracking (FCC) units will generate a large amount of flue gas. A large amount of air pollutants such as sulfur oxides and nitrogen oxides contained in flue gas have brought a series of environmental problems. Reducing the emission of air pollutants including sulfur oxides and nitrogen oxides is an urgent task to protect the environment. For example, national standards GB13271-91 "Emission Standard of Air Pollutants for Boilers", GB9078-1996 "Emission Standards of Air Pollutants for Industrial Furnaces", GB13223-1996 "Emission Standards of Air Pollutants for ...
