Description
Technical field
The invention belongs to biomass gasification boiler equipment, especially relate to boiler body and use biomass fuel into promoting the circulation of qi
Change, the burner of cracking generation combustion gas.
Background technology
Country's biomass gasification burning boiler at present is all that the combustion gas generated after gasifying is directly entered boiler furnace internal combustion
It burns.Since bulging wind action of once gasifying, the surface of vaporising fuel layer will produce a large amount of high temperature flying dust in gasification,
It can enter in boiler furnace with combustion gas under the swabbing action of negative pressure, while what is entered also has the unvaporized complete, weight in part
The lighter carbon particle not burnt.Enter in this way the flying dust of burner hearth encounter less than will stick under own temperature boiler by
On hot face, dust stratification, caking phenomenon are formed, the fire tube of boiler, the blocking of convection bank are caused, reduced boiler thermal efficiency, influences
Boiler normal operation.The soot particulate matter with open fire can enter the cloth bag of flue gas system with boiler smoke and remove in into burner hearth
In dirt device, it is sticky deposited on cloth bag and the phenomenon that scaling loss cloth bag occurs.In order to ensure boiler normal operation, regular blowing out is needed to clear up
Dust stratification checks cloth bag, accordingly shortens the boiler operatiopn period, increases operation cost.
Invention content
In order to solve the above problem, a kind of biological fuel gas that the present invention provides included dedusting, improves combustion gas clean degree
Burner.
In order to achieve the goal above, the technical solution adopted by the present invention is that：A kind of autonomous dedusting gasification furnace of biomass, including
Vaporizer, vaporizer are connected to dirt pocket, and there is dirt pocket the blast tube being connected to vaporizer, dirt pocket also to go out with combustion gas
Mouthful, the taper bucket of the dirt pocket being internally provided between blast tube and gas outlet, the medial surface of the taper bucket is set
It is equipped with the gear cap of cone triangle, the taper bucket forms the annular fuel gas channel for stopping lime-ash with gear cap.
Further, circumferentially and at dedusting chamber interior walls several support elements are arranged in the gear cap.
Taper ash bucket is arranged in the dirt pocket bottom.
Moving grate is set in the vaporizer, clinker groove is set in the end of fire grate.
Ash-valve is arranged in the ash bucket lower part, is communicated with clinker groove.
Air-distributing disc is arranged in the gas outlet, and air-distributing disc is made of several spinning disks.
Implement technical solution of the present invention, the combustion gas generated after gasification of biomass flows into dirt pocket, combustion gas from bottom to top
In contain do not burn carbon particle, flying dust is stopped and settled to reach dust removal process purpose by conical head and gear cap wall surface, also profit
During rising flowing with combustion gas, heavier particulate matter, lime-ash generate natural subsidence due to gravity, and clean combustion gas that treated is again
Boiler Furnace chamber inner combustion is entered, the particulate matter and dust to settle down is stored in dirt pocket lower taper bucket, and row is opened in timing
Grey valve is discharged into clinker groove.Combustion gas after treatment enters burning in boiler, and the dust of generation is just fewer, reduces adhesion
In the probability of boiler heating surface, while the ash quantity for entering later stage bag-type dust removal system can also largely reduce, and both ensure that boiler exists
The running thermal efficiency also improves efficiency of dust collection in flue gas system, is conducive to environment protection emission.
Other features of the present invention：
1, blast tube and gas outlet use certain difference in height reversed arrangement, and gasification burning is in the process with " S "
The path of shape passes through, and keeps combustion gas speed slack-off in this course, and particulate matter meeting nature settles downwards.
2, the conical device being arranged in expansion chamber, changes flow direction and the speed of flue gas, while the combustion gas with flying dust
Inner wall with conical device generates collision, is settled downwards to isolate part dust and particulate matter.
Description of the drawings
Fig. 1 is the structural schematic diagram of the autonomous dedusting gasification furnace of biomass.
Specific implementation mode
As shown in Figure 1, the main body of the autonomous dedusting gasification furnace of biomass is furnace wall 15,2 He of vaporizer is opened up inside furnace wall 15
Dirt pocket 9.
Fire grate 13 is arranged in 2 lower section of vaporizer, and vaporizer 2 is connected to feed inlet 1.Vaporizer 2 be connected to the bottom of dirt pocket 9 and
In connectivity part, blast tube 8 is set.
The middle part of dirt pocket 9 sets up the taper bucket 5, has the gear cap of the medial surface setting cone triangle of the taper bucket 5 of opening
6, gear cap 6 is fixed by support element 7.The taper bucket 5 forms annular fuel gas channel with gear cap 6.
Biomass fuel enters from feed inlet 1 in gasification furnace, and vaporizer 2 is entered under the movement of moving grate 13,
Gasification, and combustion is carried out under the action of 14 air distribution of distribution plenum, the fuel gas of generation enters under the action of negative pressure from blast tube 8
In dirt pocket 9.The clinker generated in gasification is discharged under the movement of fire grate 13 in clinker groove 12.
Combustion gas into dirt pocket 9 is flowed up through annular fuel gas channel, during this, biomass gasification burning and gear
Cap inner wall generates to be collided for the first time, and partial particulate object, flying dust in combustion gas can be downwards deposited in taper ash bucket 10.
The combustion gas flowed out from annular fuel gas channel, can be from four circumferentially intermediate receipts when by the position of taper means for removing lid of furnace 5
Flowed out after holding together, the inner wall of this process combustion gas and the taper bucket 5 generates collision again, again the partial particulate object in sedimentation combustion gas and
Flying dust.The particle dust touched down is deposited to downwards taper ash bucket 10 in the annular fuel gas channel between gear cap 6 and dirt pocket 9
It is interior.
Gas outlet 4 is passed through in the combustion gas flowed out from the taper bucket 5, enters boiler after being mixed with the air distribution that distribution plenum 3 supplements
Interior burning.
The dust stratification in taper ash bucket 10 in dirt pocket 9 is opened ash-valve 11 and is discharged into clinker groove 12.It is cleared up.
Quick operating valve is set at clinker groove 12, is convenient to clean clinker.
