| titleOfInvention | Wet denitration and dust removal process and equipment for recycling denitration agent |
| abstract | The invention discloses a wet denitration dedusting process and equipment for recycling a denitration agent. The denitration agent is an oxidant and an absorbent, the equipment comprises a wet denitration dust removal tower arranged at the rear end of the desulfurization system, and the circular spraying ClO is arranged in the tower from bottom to top in sequence 2 Primary oxidation zone, circulating spraying alkali liquor and H 2 O 2 Oxidant recycling area and circulating spray H 2 O 2 、Fe 2+ And an alkali liquor forms a secondary oxidation dedusting area of the absorbent, the secondary oxidation dedusting area is sequentially and externally connected with a turbidity removal softening system and an electrodialysis denitration device, the electrodialysis denitration device regenerates the nitrate wastewater subjected to turbidity removal softening into the alkali liquor, and meanwhile, part of nitrate is reduced and removed by iron powder in a nitrate-enriched compartment under the condition that the pH value is 1-6, and Fe is generated 2+ The absorbent is prepared again and then is reused in a secondary oxidation dust removal area. The process comprises the following steps: and the desulfurization flue gas is discharged after sequentially passing through a primary oxidation zone, an oxidant recycling zone and a secondary oxidation dedusting zone in the wet denitration dedusting tower. |
