Description

technical field [0001] The invention relates to the technical field of industrial flue gas treatment, in particular to a boiler flue gas dewhitening equipment. Background technique [0002] At present, most of the flue gas from domestic coal-fired power plants or other chemical industries has undergone wet desulfurization before discharge, and the temperature has dropped to a certain temperature. At this time, the flue gas is usually saturated wet flue gas, and the flue gas contains a lot of water. Steam, water vapor contains more dissolved salts, SO 3 , gel dust, fine dust, etc. If the flue gas is directly discharged from the chimney and enters the ambient air with a lower temperature, since the saturated humidity of the ambient air is relatively low, the water vapor in the flue gas will condense to form a wet plume during the temperature reduction of the flue gas. [0003] With the continuous improvement of environmental protection requirements, the requirement to reduce...
