Annular sprayer for sleeve kiln

The utility model provides an annular sprayer for sleeve kiln, it is penetrated tub including drawing, bellmouth entrance pipe, hybrid tube, diffuser pipe, and still including connecting the outer tube gas combustion ware on this draws the outside of penetrating the pipe, this outer tube gas combustion ware is set to and is suitable for the externally to receive the gas and makes the gas burn in drive air and recirculated flue gas's mist. Because the utility model discloses outer tube gas combustion ware has been add, make the gas to burn in drive air and recirculated flue gas's mist, therebyit improves recirculated flue gas and drives the mixed gas temperature behind the air mixing to release released heat, make it be higher than sodium, the junction temperature (800 DEG C ) with fixed attention of potassium steam, thereby avoid sprayer jam problem to appear, this has not only improved the life of sprayer and sleeve kiln's operation ratio, still can realize the fractional combustionof fuel, be favorable to i
