Description
Technical field
The utility model belongs to biomass gasification device, the biomass gasifying furnace that to relate in particular to a kind of material attribute be the stalk class.
Background technology
At present, the field that utilizes mode mostly to use or abandon of vast rural area biomass material for simple burning, even burning, its thermo-efficiency utilization ratio is also very low, environmental pollution is serious.In recent years, some areas begin to attempt adopting the gasifying stalk technology to solve the waste problem of resource, but existing stalk gasifier is also unreasonable in design, its complex structure, not easy to operate, because stalk can not carry out according to gasification principle fully, cause material vaporization rate and fuel value instability in gasification, tar content is higher, the stalk dust can not effectively catching in stove.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and the material vaporization rate is stable, but the biomass gasifying furnace of stalk dust effectively catching in stove.
For achieving the above object, the utility model is achieved in that a kind of biomass gasifying furnace, comprises burner hearth; Middle part at described burner hearth is provided with fire grate; Be provided with reinforced propulsive mechanism on the top of described fire grate; Be provided with dust trapping medium storehouse in the bottom of described fire grate; Outside in described dust trapping medium storehouse is provided with strainer and recycle pump; The outlet in described dust trapping medium storehouse communicates with the inlet of strainer through pipeline; The outlet of described strainer communicates through the inlet of recycle pump with dust trapping medium storehouse.
As a kind of preferred version, the utility model is provided with water jacket at the outer wall of described burner hearth; Inwall at described burner hearth is provided with thermal insulation layer.
As another kind of preferred version, the utility model is provided with water level gauge on described water jacket.
The utility model is simple in structure, and by using reinforced propulsive mechanism, the material vaporization rate is stable.In addition, the utility model is owing to employing dust trapping medium chamber structure, but its stalk dust effectively catching is in stove.
Description of drawings
Below in conjunction with the drawings and specific embodiments to being described further.Protection domain of the present utility model will not only be confined to the statement of following content.
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in the figure, a kind of biomass gasifying furnace comprises burner hearth 1; Be provided with fire grate 2 at the middle part of described burner hearth 1; Be provided with reinforced propulsive mechanism 3 on the top of described fire grate 2; Be provided with dust trapping medium storehouse 4 in the bottom of described fire grate 2; Outside in described dust trapping medium storehouse 4 is provided with strainer 5 and recycle pump 6; The outlet in described dust trapping medium storehouse 4 communicates through the inlet of pipeline with strainer 5; The outlet of described strainer 5 communicates through the inlet of recycle pump 6 with dust trapping medium storehouse 4.Referring to Fig. 1,11 is ash removing hole, when the needs burner hearth is cleared up, can open ash removing hole 11 and carry out the deashing operation.
For preventing that heat from losing, the utility model is provided with water jacket 7 at the outer wall of described burner hearth 1; Inwall at described burner hearth 1 is provided with thermal insulation layer 8.
Be the quantity of circulating water of control water jacket 7, the utility model can be provided with water level gauge 9 on described water jacket 7.
When actually operating, the utility model is sent into biomass material in the burner hearth 1 from feeding port 10, carries out gasification reaction.The inflammable gas that upper furnace produces is 12 discharges through the air outlet.In reaction, the dust that is fallen by fire grate 2 is reclaimed by the liquid medium in the dust trapping medium storehouse 4.When the solid impurity in the dust trapping medium storehouse 4 increases, but ON cycle pump 6 by strainer 5 solid impurity is separated, so just can guarantee recycling of liquid in the dust trapping medium storehouse 4.The reinforced propulsive mechanism 3 of the utility model can adopt spiral precession mode that material is advanced.
Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
