The invention discloses an optimized integrated method for denitrification, deacidification and dust removal of domestic waste incineration flue gas. It includes the following steps, step 1: the original flue gas enters the original flue gas pipeline under the action of the terminal induced draft fan; step 2: the NaClO 2 solution is atomized and enters the aerosol dosing area; step 3: the NaClO 2 aerosol In the uniform distribution area, NaClO 2 aerosol and flue gas oxidize NO to high-valence nitrogen oxides; Step 4: Absorb and deacidify slaked lime slurry; Step 5: Absorb and deacidify NaOH solution; Step 6: React in the SDA tower itself The generated solid by-products are partially discharged through the ash hopper at the bottom of the SDA tower, and the other part enters the downstream flue through the flue gas outlet of the SDA tower; . The invention has the advantages of no white smoke plume, no waste water generation, no catalyst consumption, low overall investment cost and low system energy consumption. |
