| titleOfInvention | Liquid-phase oxidation multistage absorbed flue gas desulfurization and denitrification technology and device |
| abstract | The invention discloses a liquid-phase oxidation multistage absorbed flue gas desulfurization and denitrification technology and a liquid-phase oxidation multistage absorbed flue gas desulfurization and denitrification device, and belongs to the technical field of flue gas treatment. The technology comprises the following steps of: performing pre-desulfurization by contact reaction of flue gas and a desulfurizing agent which absorbs a part of sulfur dioxide in the flue gas to obtain desulfurized slurry; performing liquid-phase oxidation and partial absorption on the pre-desulfurized flue gas, and oxidizing nitric oxide in the flue gas into nitrogen dioxide; and performing contact reaction on the oxidized flue gas and the desulfurized slurry to absorb the nitrogen dioxide and the rest sulfur dioxide in the flue gas. The device comprises a desulfurization and denitrification tower and a tower kettle arranged at the bottom of the desulfurization and denitrification tower, wherein a first spraying layer, a sieve plate layer, a second spraying layer and a third spraying layer are sequentially arranged above the tower kettle from bottom to top; and the sieve plate layer is communicated with the second spraying layer through an oxidant slurry tank positioned outside the desulfurization and denitrification tower, and the first spraying layer and the third spraying layer are communicated with the tower kettle through external circulating pumps respectively. The technology is simple and high in desulfurization and denitrification efficiency during desulfurization and denitrification of the flue gas. |
