Description

Technical Field

[0002] Flue gas desulfurization and denitrification technology is a flue gas purification technology used in chemical industries that generate a lot of nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. During purification, they are mostly carried out through desulfurization and denitrification towers. The flue gas is discharged after purification. Among the combined removal technologies, some use a combination of flue gas desulfurization and flue gas denitrification technology, and some use adsorbents to remove nitrogen oxides and sulfur oxides at the same time, both of which can achieve a high removal effect;

[0003] As shown in the reference case "A flue gas desulfurization and denitrification device" publication number "CN218924290U", the desulfurization and denitrification effects of the flue gas are tested after the flue gas treatment is completed. The flue gas that fails the test will be re-desulfurized and denitrified, thereby effectively reducing the direct discharge of flue gas that has not been thoroughly purified, which causes environmental pollution. In addition, the flow rate of the flue gas entering the two reaction towers can be detected, and the amount of the reaction solution sprayed out can be controlled according to the flow rate of the flue gas. While improving the flue gas purification effect, the use of the reaction solution can be reduced when the flue gas is less, thereby reducing the purification cost;
