The invention relates to the technical field of environmental protection and discloses a sodium-based spray-drying desulfuration system. The sodium-based spray-drying desulfuration system comprises a desulfurization device, an alkali liquor supplying device, a pneumatic dust conveying device, a compressed air supplying device and a control device. According to the sodium-based spray-drying desulfuration system disclosed by the invention, hard problems of the existing wet-process desulfuration technologies, such as scaling, blockage, difficulty in rich solution treatment, corrosion, wear and formation of white fume are solved, and meanwhile, the problems of a calcium-based spray-drying desulfuration process that a slurrying process is complicated, the one-time investment is big, and pumps, pipes and spray devices are blocked are solved. In addition, when in use, the sodium-based spray-drying desulfuration system disclosed by the invention is high in desulfuration efficiency, small in floor area and remarkable in water-saving and energy-saving effect.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sodium-based spray drying desulfurization system. Background technique [0002] During the production process, when fuels containing sulfur are burned in various furnaces and kilns, the sulfur in the fuel reacts with the oxygen in the air at high temperature as follows: [0003] S+O 2 = S O 2 Sulfur dioxide (SO 2 ). [0004] Sulfur dioxide is a poisonous and harmful gas that seriously endangers human health. In the prior art, in order to eliminate the harm of sulfur dioxide to human health, the following methods are often used to remove sulfur dioxide in the flue gas (referred to as desulfurization): using some alkaline substances (such as calcium oxide or magnesium oxide), by adding water to prepare into calcium hydroxide (Ca(OH) 2 ) or magnesium hydroxide (Mg(OH) 2 ) slurry, and then pumped into the absorption tower to fully contact with the flue gas, ...
