Description

Faggot aerogenesis stove

Technical field

The utility model relates to combustible biomass is fuel is realized gasification conveying burning gas with the pyrolysis mode of operation vapourizing furnace.

Background technology

The agent structure of biomass gasifying furnace includes the return-air chamber of furnace chamber and furnace chamber bottom, the cavity dividing plate is provided with ventilating pit between return-air chamber and the furnace chamber, biomass fuel in the furnace chamber gasifies in the pyrolysis and combustion state, and the gas based on carbon monoxide of output is directly drawn by the gas line of upper furnace.The existing biomass gasifying furnace that comprises numerous straw gasification stoves has also adopted different technique means respectively by the technical purpose difference, as adds water jacket flue, taper fire door, bell water seal or moisture separator or the like is set.Comprise the technician, people generally believe that this series products can not use the big biological material of water content, has only for example cool extremely suitable degree of drying that shines such as corn stalk, plant stem-leaf, bamboo and wood, and be cut into segment, to avoid the moisture content interference to influence even can't make furnace gas work as far as possible; Prior art is ubiquity gasification work deficiency and gas production rate problem of unstable also, but also smoke discharge pipe need be set, and is bigger to air environmental pollution pressure.

Summary of the invention

Goal of the invention of the present utility model be to provide a kind of be exactly the bigger biomass material of moisture content be the faggot aerogenesis stove that fuel also can be stablized aerogenesis output, the biomass material roots of plants cauline leaf of described high humidity, forage, timber, straw etc.The faggot aerogenesis stove technical scheme that the utility model provides, its major technique content is: a kind of faggot aerogenesis stove, the return-air chamber that comprises burner hearth and burner hearth below, the mouth of pipe is communicated in burner hearth internal upper part space and is provided with the twice airway, one airway wherein drawn furnace cavity after descending in furnace cavity, second airway is drawn outside the stove, and is descending until the merging that communicates of the burner hearth fairlead with the first road airway outside stove, transfers to the combustion gas mouth of pipe by total delivery conduit.

In above-mentioned overall technical architecture, the first road airway comes downwards in burner hearth and is no more than zone of oxidation and place, reducing zone line of delimitation.

Through facts have proved, be fuel with the higher biomass material of wetness exactly, as be soaked with rain, or in the fog, or now tap, or withered mashed roots of plants cauline leaf, forage, timber, straw etc., through simply being that cool the solarization just can be used as pyrolysis aerogenesis fuel, in its fuel diameter 8-20cm can be arranged, height is that the bulk material of 8-20cm is some, other fuel soft or that volume is little is clogged around it, these fuel had both used hand can obviously feel moist, still can normal gas producing work by faggot aerogenesis stove of the present utility model, its steam cooling water is mainly separated by each fragment position of total delivery conduit, it is abundant that it has pyrolysis, gas production rate is stablized lastingly, the handling characteristics of smokeless, juggle is a charcoal by pyrolysis finally, and the residue after other fuel combustion can be used as the fertilizer that farm crop grow up.This faggot aerogenesis furnace structure structure and using method are simple, burner, banking operational requirement are easy, because its adoptable fuel range is wide, so more suitable urban residents user use and utilization of waste material.Faggot aerogenesis stove of the present utility model has also been abolished the conventional thought fixed pattern that working furnace must have fume emission, this faggot aerogenesis furnaceman does not have fume emission in doing, Working environment is very clean, so just can use needs arbitrarily to put its position according to the user, its non-pressurized mode of operation has safety, technical characterstic efficiently.

Embodiment

Describe technology contents of the present utility model in detail below in conjunction with the concrete structure of implementing shown in the accompanying drawing.

As shown in Figure 1, faggot aerogenesis stove of the present utility model comprises burner hearth 1, and burner hearth 1 below is communicated with burner hearth by ventilating pit 3 and is provided with return-air chamber 2, and fire grate is provided with ventilating pit 3 places, and burner hearth feeding mouth periphery is provided with bell 5 and fastens rear enclosed furnace cavity water sealed tank 4.The mouth of pipe makes progress, is provided with twice airway 8,9 by burner hearth 1 upper space guiding output air-flow, one airway 8 wherein walked downwards in burner hearth 1 space, burner hearth 1 space is laterally drawn at the place, line of delimitation of zone of oxidation when its descending maximum position is no more than burner hearth raw material pyrolysis work and reducing zone then; The second road airway, 9 pipelines are caused the burner hearth air-flow outside the stove by the burner hearth inner spout, and are descending along furnace body outer wall, communicate until drawing mouth of pipe merging with the burner hearth of the first road airway 8, merge the back and transfer to the combustion gas mouth of pipe 16 by total delivery conduit 10, as gas-cooker.Described twice

airway

8,9 can be separation, separate, communicates until merging; Also can implement structure as this, as shown in Figures 2 and 3, the burner hearth mouth of pipe of twice

airway

8,9 adopts the same mouth of pipe, this airway burner hearth mouth of pipe is preferably the position that is provided with that opening makes progress, airway by water sealed tank bottom around being divided into the twice airway by division plate 6 to hearth wall, wherein one airway 8 laterally drawn burner hearth by inboard wall of burner hearth down to the place, line of delimitation that is no more than zone of oxidation and reducing zone, the second road airway 9 passes the furnace wall and draws outside the stove, along the horizontal burner hearth fairlead of hearth outer wall down to the first road airway 8, and the merging that communicates with the first road airway.Test shows, is provided with the through hole 7 that the twice airway is connected in division plate, can more help the stable output of combustion gas.Total delivery conduit 10 merges the mouth of pipe 18 with the twice airway and is communicated with, each section of its pipeline is provided with the water coolant mouth of pipe, be connected with the water coolant container on the water coolant mouth of pipe, can also be as shown in Figure 1, be connected with air water separator 11 on total delivery conduit 10, moisture content retardance material is equipped with in the bottom of air water separator 11, when total delivery conduit 10 pipelines are imported this air water separator 11, steam composition in the air-flow is under retardance and cooling effect, separate with combustion gas, combustion gas then continues to be sent to the combustion gas mouth of pipe 16 along pipeline.In the middle of this enforcement structure, the expansion box 13 that is connected with strumbox 12 and communicates between total delivery conduit 10 and the combustion gas mouth of pipe 16 with the strumbox delivery port, the strumbox filtering flue dust material in the combustion gas, make combustion gas more pure, expansion box 13 bottoms are provided with cooling water outlet.

The using method of this faggot aerogenesis stove is: pack in the burner hearth 1 and smash the fuel feedstocks of pressure, wherein fire door 14 places dose siccative so that ignite, bell 5 buckle closures in water sealed tank 4, thereby be that good space sealing is implemented in the pyrolysis work of fuel in the burner hearth 1.After opening fire door 14 fire fuel fire door is sealed, open blower fan 15, carry suitable pressure air to return-air chamber 2, impel fuel fully pyrolysis work in burner hearth 1, in 2-5 minute time, combustion gas mouth of pipe place begins that stable combustion gas output is arranged, adjusting burnt gas valve makes the combustion gas flare reach requirement height, burning work.In the real work, 0.6 cubic metre of left and right sides fuel feedstocks of filling in the burner hearth, its lasting aerogenesis working hour can reach more than 3 hours.
