The present invention has the advantage that the gas in the present invention below put flitch enters in fluctuation up and down compared with prior art
Form can make material above put flitch that wave movement up and down be presented, promote between material particles it is mutual collide and
Material mutual convection current under airflow function, forms stable recurrent state, and material is made to be uniformly dispersed in the combustion chamber of combustion furnace,
The uniform and complete of burning；Flue gas after burning has obtained further utilization, and not only heat is recycled, and follows simultaneously
Partial fume after ring can also carry out the material in put flitch to blow boiling, avoid material from agglomerating in put flitch and stop
It stays.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
As shown in Figure 1, a kind of low oxygen combustion furnace for furfural dregs fluidized bed, including shell 10, successively set from top to bottom
It is offered respectively on separator 50 and put flitch 60 in shell 10, the shell 10 between the separator 50 and put flitch 60
10 two sides of shell of feed inlet 40 and discharge port 30,50 top of separator respectively offer a gas outlet 70；It further include being set to set
The admission gear 20 of the lower section of flitch 60, the admission gear 20 include the inlet body 26 set on 60 lower section of put flitch, it is described into
Tracheae body 26 be in sinusoidal image shape and its highest point close to put flitch 60, minimum point close to 10 bottom of shell, the inlet body
26 tops are uniformly provided with air inlet 261.
Entering the gas of the lower section of put flitch 60 can make the material of 60 top of put flitch be in upper and lower wave
Now wave movement up and down promotes mutual collision and material mutual convection current under airflow function between material particles, makes
Material is uniformly dispersed in the combustion chamber of combustion furnace, the uniform and complete of burning.Wherein, separator 50 be generally filter cloth bag or
Dust filter unit etc. does not limit its type or specifications and models as long as the dust separation by flue gas and burning can be played
Deng.
The admission gear 20 further includes mixing chamber 24, and gas inlet pipe 21 that outlet side is connected to mixing chamber 24 helps
Air intake duct 22, smoke backflow air inlet 23, and the total air inlet 25 being opened on 60 lower section shell of put flitch are fired, it is described total
Air inlet 25 is connected to setting with mixing chamber 24；First is also connected between one gas outlet 70 and smoke backflow air inlet 23
Smoke backflow pipe 71.Material burn in shell 10 after flue gas successively from gas outlet 70, the first smoke backflow pipe 71, flue gas
Flow back air inlet 23, enters eventually into mixing chamber 24, and after being sufficiently mixed in mixing chamber 24 with coal gas and combustion air, weight
It newly enters in shell 10 and burns with material, so that flue gas has been obtained further utilization, take full advantage of the heat of flue gas,
The most of of heat is avoided to be lost.
Wherein, the inlet end bore of the mixing chamber 24 is greater than outlet side bore, this is primarily to between each gas
Sufficient incorporation time further increases efficiency of combustion in order to enter being uniformly distributed in shell 10.The combustion air into
