The invention discloses a flue gas desulfurization and denitration method and device. The flue gas desulfurization and denitration method includes step S1 of introducing a neutral absorption liquid: introducing a neutral solution into a reaction tower, and making the neutral solution completely submerge the bottom of the reaction tower; step S2 of heating: heating the neutral solution in the stepS1, and obtaining a hot neutral solution; step S3 of atomizing an absorption liquid: atomizing the hot neutral solution in the step S2; step S4 of introducing flue gas and ozone: introducing the ozoneand the flue gas into the reaction tower at an ozone and oxynitride molar ratio of 1-2.5:3, and obtaining a flue gas mixture. The device is reasonable in design and high in practicality. By sprayingheated clear water on the flue gas mixture, the flue gas mixture can come into full contact with the clear water, the washing efficiency is improved, and the temperature of the flue gas mixture can bequickly improved in the process of mixing the flue gas mixture and the spray, thereby facilitating denitration of the flue gas mixture in subsequent processes.
Description
technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a flue gas desulfurization and denitrification method and device. Background technique [0002] With the increasing concern of the international community on marine environmental pollution, the pollution of ship flue gas is becoming more and more prominent, among which nitrogen oxides (NOx) and sulfur dioxide are the most harmful to the ecological environment among diesel engine emissions, including SO2, NOx A large amount of waste gas discharge has caused serious environmental pollution problems. Currently, the main means of controlling the emission of harmful gases such as SO2 and NOx is flue gas purification. [0003] After retrieval, the patent document with application number 201310613965.3 discloses a flue gas desulfurization and denitrification method and device, especially a desulfurization and denitrification process system involving flue gas of large mobile f...
