Description

Biomass gasifying furnace
Technical field
The present invention relates to gas-fired equipment technical field, especially a kind of biomass gasifying furnace.
Background technology
Biomass gasifying furnace is that one kind makes biomass be heated in zoneofoxidation, occurs oxidation reaction generation carbon dioxide, and Carbon dioxide is occurred reduction reaction in reducing zone and carbon and water vapour and produce the imflammable gas such as carbon monoxide, methane, hydrogen Molecule after, then through fuel area in preparation carry out Pintsch process, drying, the equipment to obtain preferable firepower；Due to it safely, defend Raw, environmental protection, and biomass material is by agricultural crop straw, forest tree castoff, edible fungi residues, cattle and sheep animal manure and all flammable things Matter is made, and is a kind of inexhaustible regenerated resources, therefore be widely applied；But existing biogas Change stove and exist that the recovery time is shorter, the problem of reduction reaction is not exclusively and the heat that produces of zoneofoxidation is lost in because of radiation.
The content of the invention
The present invention provides a kind of biomass gasifying furnace, and the biomass gasifying furnace can solve existing biomass gasifying furnace and deposit Shorter in the recovery time, reduction reaction is not exclusively and the heat that produces of zoneofoxidation because of radiation the problem of be lost in.
In order to solve the above problems, the technical solution adopted in the present invention is：This biomass gasifying furnace, including stove sheet There are heated oxide area, reducing zone and fuel area in preparation in body, the furnace body successively from the bottom up；Corresponding to the reducing zone U-shaped reduction passage is provided with by deflector in the furnace body；Corresponding to the furnace body periphery in the heated oxide area Shield has water vapour to occur room；The venthole that room occurs for the water vapour is connected with the entrance of the reduction passage.
In above-mentioned technical proposal, more specifically technical scheme can also be：The deflector includes transverse slat and stood side by side In at least two risers on the transverse slat；The deflector has the transverse slat to be oppositely arranged, two that the riser is staggered It is individual.
Further：Provided with the fire grate for conveying and carrying biomass in the heated oxide area, the institute below the fire grate Furnace body is stated provided with combustion adjuvant entrance.
Further：Exported corresponding to combustible gas is offered on the furnace body of the fuel area in preparation.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, due to being provided with U-shaped reduction passage by deflector in the furnace body corresponding to reducing zone；Corresponding to heated oxide area The furnace body peripheral protective have water vapour occur room；Water vapour occurs the venthole of room and is connected with reducing the entrance of passage； So, carbon dioxide is occurred reduction reaction with carbon and water vapour in U-shaped reduction passage, extend its reaction time, no But their reduction reactions are ensure that fully and completely, moreover, the thermal energy that heated oxide area gives off, can make water vapour occur room Interior boiling water directly produces water vapour, has saved the energy；
2nd, at least two risers for transverse slat being included due to deflector and being stood on side by side on transverse slat；Deflector has the transverse slat relative Set, be staggered two of riser；So, on the premise of complete reduction reaction being met ensureing the length for reducing passage, Structure is simpler；
3rd, because the furnace body below fire grate is provided with combustion adjuvant entrance；Biomass combustion can be made more complete.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Embodiment one
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
There is heated oxide area III in biomass gasifying furnace shown in Fig. 1, including furnace body 1, furnace body 1 successively from the bottom up, go back Former area II and fuel area in preparation I；Corresponding to deflector 2 is provided with the furnace body 1 of reducing zone II, deflector is by transverse slat 21 and side by side Two risers 22 stood on transverse slat 21 are constituted；Deflector has two, and the transverse slats 21 of two deflectors is oppositely arranged, riser 22 is handed over Mistake sets the U-shaped reduction passage constituted in reducing zone II；There is water vapour corresponding to the peripheral protective of furnace body 1 in heated oxide area III Generation room IV；Water vapour occurs room IV and is provided with the I of the water inlet IV and O of venthole IV, and the O of venthole IV of room IV occurs for water vapour with going back The I of entrance II of former passage is connected；The O of outlet II of reduction passage is connected with the I of entrance I of fuel area in preparation I, corresponding to fuel Combustible gas is offered on the furnace body 1 of area in preparation I and exports I O, combustible gas exports I O and is connected with the entrance of gas-cooker；Heat oxygen Change provided with the fire grate 3 for conveying and carrying biomass in area III, the furnace body 1 of the lower section of fire grate 3 is provided with the I of combustion adjuvant entrance III；Plus The carbon dioxide gas in thermal oxide area III exports III O and is connected with reducing the I of entrance II of passage.During work, heated oxide area III gives birth to Into carbon dioxide occur reduction reaction with carbon and water vapour in U-shaped reduction passage, extend its reaction time, not only protect Their reduction reactions are demonstrate,proved fully and completely, moreover, the thermal energy that heated oxide area gives off, can make water vapour occur indoor Boiling water directly produces water vapour, has saved the energy.
Embodiment two
Deflector is made up of transverse slat 21 and four risers 22 stood on side by side on transverse slat 21；Remaining is identical with embodiment one.
