| titleOfInvention | Rotary kiln flue gas denitration system and device |
| abstract | The utility model discloses a rotary kiln flue gas denitration system and device, the high temperature flue gas that the rotary kiln combustor burning produced and upper reaches incoming flow material reverse flow, both intermix, accomplish heat exchange, and flue gas temperature reduces gradually along the journey. The rotary kiln body section is provided with a spray gun at the flue gas temperature of 850-1050 ℃, the denitration agent is atomized and then sprayed into the rotary kiln body, and the denitration agent and NOx are subjected to mixed reaction to complete the denitration process. The denitration agent is provided by the ground denitration agent supply module, the denitration agent and the atomized air are conveyed to the rotary kiln body through a rotary sleeve structure, the process of conveying the medium from the static equipment to the dynamic equipment is realized, and then the denitration agent is sprayed into the rotary kiln through the two-stage nozzle group to carry out denitration reaction. For preventing the flue gas from radiating the spray gun body high temperature, the spray gun adopts external sleeve structure, when the spray gun revolves to the high-order by the low level along with the rotary kiln body, opens sleeve deashing valve automatically, and the material that piles up in the clearance sleeve protects nozzle, sleeve not to receive the material jam. The utility model discloses successfully solved rotary kiln denitration difficult problem such as rotary kiln, and had advantages such as the system is simple, the energy consumption is low, take up an area of for a short time, the investment is low, had very big application prospect under the environment-friendly situation that is increasingly harsh. |
