For deficiency of the prior art, the invention provides a kind of oxygen-enriched spray of incinerator for tail gas of carbonization stove burning
Mouth.This nozzle is formed by the calcining of high temperature resistant, wear resistant corrosion resistant material at high temperature, can be strong, strong degree of friction in high temperature, highly corrosive
Work under environment, and this nozzle possesses injection, and oxygen-enriched air is uniform and stable, area is maximum.
Technical scheme is as follows: devises a kind of incinerator rich-oxygen nozzle for tail gas of carbonization stove burning.Bag
Include ring flange, ring flange baffle plate, jet pipe, spout and flow distribution plate；Ring flange dimidiation, there are two fixing holes every piece of top；Method
Blue disk 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 flow distribution plate,
Flow distribution plate is with 100、200、300Angle 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 to spray or complementary angle
Dress form, the big I of complementary angle is adjusted according to wind-force and exhaust gas volumn flexible in size.Size Selection according to incinerator installs incinerator
The quantity of rich-oxygen nozzle and distance.
The invention has the beneficial effects as follows:
1st, ring flange can be dismantled, with pipeline connected mode using being flexible coupling, it is possible to decrease mechanical shock docking port brings damage.
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 combustibility and the fire of fuel
The stability of flame.
3rd, incinerator rich-oxygen nozzle a length of 0.2m～0.5 m, material thickness is 0.02m～0.05 m, in suitable incinerator
Portion's architectural characteristic, convenient and flexible installation.
4th, formed using the material modified high-temperature calcination of carborundum, there is the spies such as high temperature resistant, the strong, life-span length of abrasion and corrosion resistance
Point.
