| titleOfInvention | A kind of integrated process method of wet desulfurization and denitrification |
| abstract | The invention discloses an integrated wet desulfurization and denitrification process. The flue gas after dedusting is passed into a washing tower containing an ion catalyst, and an oxidation-reduction reaction occurs in a reaction tank, and the flue gas at the entrance of the washing tower is discharged. The temperature is not lower than 50 degrees, and the waste gas in the washing tower is washed by spraying the absorption agent; when the washing liquid meets the requirements of sulfate ions after oxidation, it is pumped into the concentration drying tower through a circulating pump, and fresh detergent is replenished in time . The invention proposes to make maximum use of the wet desulfurization and denitrification process, has the advantages of small footprint and low investment, and reduces the chemical cost of wet denitrification as much as possible. In the absorption stage, cheap urea and ammonia water are used in combination with other auxiliary agents for absorption, and in the redox process In the stage, low-cost catalysts are used to catalytically oxidize NO and SO2, and the corresponding sulfate by-products are obtained through the concentration tower. Therefore, on the basis of ensuring a certain desulfurization and denitrification efficiency, the cost is reduced as much as possible, and additional benefits are obtained. |
