The technical solution of the utility model is as follows：Devise a kind of oxygen-enriched spray of incinerator for tail gas of carbonization stove burning
Mouth.Including ring flange, ring flange baffle plate, jet pipe, spout and flow distribution plate；There are two fixations ring flange dimidiation, every piece of top
Hole；Ring flange baffle plate is rounded, and rear end is connected with jet pipe；The cylindrical shape of jet pipe, is connected with the spout of rear end；Spout is provided with point
Stream plate, flow distribution plate is with 100、200、300 Angle be embedded in spout internal to both sides horizontal tilt.
Further, nozzle is installed on the combustor both sides middle position of incinerator, using the peace to spray or complementary angle to spray
Dress form, the big I of complementary angle is adjusted according to wind-force and exhaust gas volumn flexible in size.Incinerator is installed according to the size Selection of incinerator
The quantity and distance of rich-oxygen nozzle.
The beneficial effects of the utility model are：
1st, ring flange can be dismantled, and adopted with pipeline connected mode and be flexible coupling, it is possible to decrease mechanical shock docking port brings damage
It is bad.
2nd, spout internal is provided with flow distribution plate, and oxygen-enriched air, with the entrance incinerator of advection, is at 0.4m in jet length
Projected area accounts for incinerator cross-sectional area 80%, oxygen-enriched air be evenly distributed and area is big, enhance the flammable and fire of fuel
The stability of flame.
3rd, a length of 0.2m～0.5 m of incinerator rich-oxygen nozzle, material thickness is 0.02m～0.05 m, is adapted in incinerator
Portion's architectural characteristic, convenient and flexible installation.
4th, formed using the material modified high-temperature calcination of carborundum, with spies such as high temperature resistant, the strong, life-span lengths of abrasion and corrosion resistance
Point.
