The structure of this device comprises body of heater 1 and screw feeder structure 2, spiral slagging device 3 and the transmission rig 4 that has thermal insulation layer, it is characterized in that: be provided with destructive gasifying district A, pyrolytic gasification district B and secondary pyrolysis gasification district C in body of heater 1; The main shaft 6 that connects with shaft joint 5 is arranged in the A district; Be fixed with tooth harrow 7, splash bar 8, flight 9 and gear mill rotor 10 on the main shaft 6 successively; Rotor 10 is biological burnt to grind with the stator 11 mutually meshing formation gears mills that are fixed on end, A district, is distributed with straight line tooth and involute tooth respectively on two meshing between rotor 10 and the stator 11, and its gap realizes finely tuning with control size by shaft joint 5.Stator 11 is provided with pod 12, and one side is separated B district and C district and stopped the ascension of material, gas in the B district; The thick combustion gas that the B district can be generated imports the C district to finish last pyrolysis pyrolysis gasification on the other hand.
Below the gear mill is pyrolytic gasification district B, is provided with air distribution plate 13, main jet pipe 14 and secondary jet pipe 15 below the B district, and main jet pipe 14 1 ends are connected on the air distribution plate 13, and the other end is connected with injector 16, and injector 16 exports 17 parallel connections with the destructive distillation gas in A district; The air that secondary jet pipe 15 sprays into or other oxygenants (vaporized chemical) play the loose combustion-supporting effect of bubbling by air distribution plate 13, oxygen that main jet pipe 14 sprays into or air or other oxygenants (vaporized chemical) will drop on the biological burnt particle jetting on the air distribution plate 13, the volume seat makes it to finish redox, catalytic pyrolysis in spouted process gasification, generate thick combustion gas.Why claim thick combustion gas because contain carbon particulate in the combustion gas, tar particulate and water vapour, wherein part is that the destructive distillation band of gas that the A district generates is gone into; B district lower end body of heater is provided with hydrolock cinder chamber 18, and cinder chamber 18 is connected with spiral slagging device 3.
The thick combustion gas that the B district generates enters secondary pyrolysis gasification district C in the annular space between pod 12 and body of heater 1 inwall under the effect of induced draft fan, remaining oxygen and carbon particulate in the thick combustion gas continue redox reaction, and catalytic pyrolysis tar particulate (C is a catalyzer), the output tube 19 of high-quality combustion gas in being arranged on the A district that generates causes the gas outlet 20 that is arranged on body of heater 1, and gas outlet 20 is connected with induced draft fan.Heat in the C district is passed to the A district through A district wall and output tube 19 and makes solid biomass destructive gasifying in it.
Body of heater 1 is provided with observation and inspection hole 21,22 and fire hole 23, the gasification situation in 21,22 difference observation and inspection A districts, hole and the B district.
On body of heater 1, also be provided with safty shield 24.
This device with the destructive gasifying of solid biomass and pyrolytic gasification originally two independently technological process unite, carbon conversion efficiency is brought up to more than 95%, and what obtain is single gas products-combustible gas, calorific value is up to 8000KJ/Nm
3More than, make solid biomass obtain fully, effectively utilize.
Four, description of drawings
Fig. 1 is this vertical combined gasification furnace for solid biomass cross-sectional view.
Five, embodiment
The solid biomass of pulverizing is transported in the destructive gasifying district A by material envelope helical screw feeder 2; The rotation of transmission rig 4 drive shaft 6 is fixed on BI homocline tooth harrow 7 on the main shaft with solid biomass uniform distribution on horizontal plane of input; Be fixed on some splash bars 8 that the stage casing of axle distributes along spiral-line and make and the loosening and radial displacement of material both can prevent that " bridges formation " phenomenon from taking place, make the material intensification be tending towards even again; The Reducing screw sheet 9 that is fixed on the main shaft Lower Half moves down the destructive distillation material continuously; The gear mill rotor 10 that is fixed on the main shaft lower end and the gear mill stator 11 that is fixed on lower end, A district evenly are sprinkled into pyrolytic gasification district B after biological Jiao of destructive distillation generation is pulverized.Rotor and stator gap can be regulated by shaft joint 5.The material that falls into vapourizing furnace B scatters on air distribution plate 13; Push kindling material by fire hole 23, light the gasification materiel on the air distribution plate; The vaporized chemical that is sprayed into by secondary jet pipe 15 passes the air distribution plate aperture the loosening burning of the gasification materiel on it is formed bubble level; Slowly open injector 16 intake valves and destructive distillation gas return valve, the high speed vaporized chemical of being injected by main jet pipe 14 entrainments the material injection on the air distribution plate to carry out gasification reaction in the power stream bundle; The material of cinder and new input is not back to bubble level in the constraint of rotor 10 and pod 12 and the furnace wall, dual function lower edge of gravity, carries out next one circulation again; The thick combustion gas that double bed (bubbling bed and spouted bed) vapourizing furnace produces is under the effect of induced draft fan, the circular clearance that is formed by upper furnace body 1 inwall and pod 12 outer rims enters secondary gasification cracking district C, at this, small carbon particles in the combustion gas and remaining oxygen continue redox reaction, and catalytic pyrolysis tar particle; High-temperature fuel gas imports heat in the dry distillation area A into by the tube wall of tapered barrel in A district and built-in combustion gas output tube 19, is used for the drying and carbonization gasification materiel; Material after the destructive distillation enters double bed fluidization gasification zone B after the gear mill pulverizes.Destructive distillation products such as the water vapour that dry distillation area A produces, destructive distillation gas, tarry vapours spray into gasification zone B through injector 16 by jet pipe 14, form the power stream bundle, and the gasification materiel that sweeps across on the air distribution plate carries out intensive redox and catalytic cracking reaction in the power stream bundle, when the power stream bundle rises to rotor 10 belows, most of gasification materiel has gasified and has finished, residual ash is molten state, with the gasification materiel intense mixing that falls by gear mill after form the ball-type plastic particle because of cooling is tending towards solidifying; Spherical plasticity lime-ash is being lowered the temperature to material and the heat transfer of following straight section furnace wall along continuation in the furnace wall decline process, final form solid particulate and crash into bubble level and fall into water seal cinder chamber 18 through the bubble level shaking-sieving, the water vapour that fervid lime-ash evokes enters gasification zone B with the secondary air that secondary jet pipe 15 sprays into by air distribution plate, forms bubble and makes vapour expanded loosening.The lime-ash that falls into grey slag bucket is discharged by spiral slag tapping equipment 3.The inflammable gas that gasification produces enters road cleaning section down by gas outlet 20 after the pooling through the built-in pneumatic tube 19 of dry distillation area A under the suction function of combustion gas induced draft fan.
