| titleOfInvention | Ammonia injection device for denitrification and cracking furnace system with same |
| abstract | The invention relates to the technical field of denitrification, and discloses an ammonia injection device for denitrification and a cracking furnace system equipped with the same. Among them, the ammonia injection device for denitrification includes: a flue gas channel section, a denitrification zone is formed inside, the denitrification zone includes a first area and a second area that jointly cover its cross section, and the flue gas channel section includes a second area corresponding to the first area. A wall surface and a second wall surface corresponding to the second area; a plurality of first ammonia injection pipes arranged on the first wall surface and used for spraying ammonia for the first area; a number of second ammonia injection pipes arranged on the second wall surface and used for spraying ammonia for the first area; For spraying ammonia in the second area; the first pipeline structure is connected with the first ammonia injection pipe and is suitable for transporting a corresponding amount of ammonia to the first ammonia injection pipe according to the nitrogen oxide content in the first area; the second pipeline structure is connected with the first ammonia injection pipe The second ammonia injection pipe is connected and adapted to deliver a corresponding amount of ammonia gas to the second ammonia injection pipe according to the nitrogen oxide content in the second region. The device can meet the denitrification operation requirements of more working conditions and improve the denitrification effect. |
