A kind of a kind of second-time burning that can effectively improve energy utilization rate, reduce pollutant emission of the energy second-time burning mating with it
Device.To achieve the above object, the present invention uses following technical scheme：
A kind of after burner of the present invention, including：Outer barrel 1, the mesh-like inner cylinder 4 in outer barrel, whirlwind stable flame pan
5th, fixation side sits 2, and the mesh-like inner cylinder 4 for being internally provided with concentric of the outer barrel 1, distribution is by advising on the mesh-like inner cylinder 4
Then with irregular same shape and hole of different shapes, the interior tube rear end connects by whirlwind stable flame pan 5, and front end is with multiple sides
To fixed screw holes 3 fix.
2 and the connection fixation of fixed screw holes 6 are sat in the outer barrel 1 and 4 rear end of mesh-like inner cylinder with fixation side,
The mesh-like inner cylinder 4 forms mesh-like cylinder by the same shape and hole of different shapes of regular and irregular
Or the cylinder of other shapes.
The stable flame pan 5 is the strip air inlet hole systematicness disk with inclination angle, can be fixed on second-time burning dress
It postpones on the contraction mouth of side.
Further, the after burner, 4 outer barrel of mesh-like inner cylinder, 1 shape do not limit to cylinder or length
Cube, or other shapes.
The beneficial effects of the invention are as follows：Since the mist of oil by atomization and wind are from the slot hole at the inclination angle of stable flame pan 5, enter
After stable flame pan opposite side, vortex is formed, is rotated at a high speed, fuel is further atomized so that fuel is of the invention a kind of secondary
Burn more abundant mouth in burner；Enter high-speed rotating mist of oil by stable flame pan 5, if there is the poor situation of atomization
Under can form oil droplet and be thrown on mesh-like inner cylinder 4, also have oil droplet and thrown by the hole of mesh-like inner cylinder 4 on 1 inner wall of outer barrel, passed through
It crosses high temperature and burns into flame, its flame is blowed to fiery cylinder front end by the whirlwind blown from rear portion, in the process, is realized second
Burning, since 4 outer barrel 1 of mesh-like inner cylinder forms flame flame from the front to the back, has elongated burning time, has added oxygen enricher meeting, make
The flue gas generated by low-temperature space is sent to forepart high-temperature region again, forces its second-time burning, makes burning more abundant, saves fuel,
Noxious material realizes nontoxic decomposition after high temperature incineration.Since outer barrel 1 is separated with outside air, make the oxygen in the outer air of cylinder can not
Nitrogen is touched in into outer barrel 1, and the oxygen inside secondary burner is preferential combustion-supporting, oxygen concentration reduces, and can not form nitrogen
Oxide so as to reduce NO_x formation, makes discharge flue gas meet the requirement of environmental protection.It is achieved in the present invention energy-saving and environment-friendly two
A purpose.
