Description

technical field [0001] The invention relates to a flue gas desulfurization discharge device. Background technique [0002] my country is a country that consumes a lot of energy. For a long time, traditional energy such as coal has been the main source. At present, thermal power generation still accounts for more than 70% of the total electricity consumption, and coal-fired boilers and kilns have become the main coal-fired users in my country. A large amount of sulfur dioxide is produced during coal combustion, which poses a serious threat to the environment. [0003] In the past, the double-alkali flue gas desulfurization technology was mostly used for desulfurization emissions. The double-alkali flue gas desulfurization technology uses sodium hydroxide solution as the starting desulfurization agent, and the prepared sodium hydroxide solution is directly injected into the desulfurization tower to wash and remove the flue gas. SO2 is used to achieve the purpose of flue ga...
