Abstract
The utility model discloses a raw material gasification furnace, which comprises a bracket, a furnace grate, a furnace body. A water-inlet and a water-outlet and a smoke-discharging mouth are arranged on the furnace body, a hearth is arranged in the furnace body, the top end of the hearth is connected with a combustion-supporting device, the innovative point is that the combustion-supporting device comprises a three-layer rotary body that is up-small and down-big, and the bottom takes an opening style form, wherein the first and the second layer of the rotary body are provided with vents, the third layer is a shielding layer. The utility model has reasonable structure, which causes the temperature in the hearth rise quickly when in the initial stage of burning, and causes the raw material fuel burn completely, so the burning efficiency and the standard of gasification are improved, the energy are utilized reasonably, the smoke-discharging time of the ignition in the initial stage is efficiently reduced and the environmental pollution caused by the discharge of the waste gas is reduced.
Description
Technical field
The utility model relates to domestic burners, specifically a kind of biomass gasifying furnace.
Technical background
Biomass gasifying furnace is a kind of raw materials such as agricultural wastes such as faggot, leaf, crop stalk that utilize, by high temperature pyrolysis, burning, make organic hydrocarbon chain fracture of HMW, generate flammable mist, for the cooking stove of urban residents' cooking, the use of heating up water, warm oneself.This gasification furnace is made up of support, fire grate, body of heater, burner hearth (combustion chamber), combustion-supporting, water jacket, heat-insulation layer, the kitchen range top, intake-outlet, air vent usually.Burner hearth is generally made by cast iron, and combustion-supporting adopts stainless steel to make usually, and the shape of combustion-supporting is generally Cylinder shape.The stove and accessory of this structure, because unreasonable structure, the natural suction of combustion-supporting is little, so cooking stove exists heat up slow, rapid heat dissipation, the smoke evacuation time is long, contaminated environment, the combustion gasification effect is undesirable, living beings weak point such as be difficult to be fully used.
The utility model content
The purpose of this utility model just provides a kind of rational in infrastructure, the biomass gasifying furnace of the good and energy-conserving and environment-protective of combustion efficiency.
The utility model purpose is achieved through the following technical solutions:
The biomass gasifying furnace that the utility model is designed, include support, grate, body of heater, body of heater is provided with intake-outlet and exhaust opening, be provided with burner hearth in the body of heater, the top of burner hearth is connected to combustion-supporting, its innovative point is to be that the Rotary-table that combustion-supporting is up-small and down-big by three layers, the bottom is open shape constitutes, and has air vent on ground floor wherein, the second layer Rotary-table, and the 3rd layer is screen layer.
Like this biomass gasifying furnace of design, biomass fuel are after the burner hearth burning, and the suction by exhaust opening enters combustion-supporting, carries out the second-time burning gasification.Because combustion-supporting is the open Rotary-table of multi-layer bottom, so can significantly improve the suction that makes progress naturally of combustion-supporting; The design of its air vent has further increased the utilization of combustion-supporting to natural air quantity again, so effectively improved second-time burning and gasification level.
The utility model is rational in infrastructure, it can make at the burning initial stage, and temperature promotes rapidly in the burner hearth, make biomass fuel be able to abundant burning, so improved efficiency of combustion and gasification level, and fully rationally utilized the energy, effectively shorten simultaneously the smoke evacuation time of initial stage igniting, alleviated the toxic emission pollution on the environment.Moreover the combustion-supporting of structure described in the utility model can adopt ceramic material, so its thermal conductivity factor is little, heat radiation is slow, thereby efficiently solves that stainless steel cylinder combustion-supporting thermal conductivity factor is big, rapid heat dissipation, problem slowly heats up.
Be described in further detail the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A schematic cross-section of Fig. 1.
The specific embodiment
As shown in Figure 1, body of heater 3 of the present utility model is the same with common biomass gasifying furnace, include the kitchen range top 9, body of heater 3, water jacket 6, heat-insulation layer 7, fire grate 2, intake-outlet 11, exhaust opening 10,, three supports 1 are arranged at body of heater 3 bottoms, this support 1 is fixed on burner hearth 4 in the body of heater 3.Burner hearth 4 is fired by fire-resistant sticking scholar and is formed, and its top is the hemisphere chimney arch, and a cylindrical interface is arranged at the top, and this interface combines with the bottom of combustion-supporting 5.The ceramic material that combustion-supporting 5 is fired by the high strength gypsum powder is made, and its structure is made of three layers of up-small and down-big Rotary-table (5a, 5b, 5c), and the bottom of Rotary-table all is made as open, is beneficial to the nature air feed.Having 12, the three layers of Rotary-table 5c of air vent on ground floor Rotary-table 5a and second layer Rotary-table 5b is screen layer.Air vent 12 can double the gasification product exit carry out combustion-supportingly once more, and screen layer can reduce flame and heat to external diffusion, also plays good insulation effect simultaneously.The arrangement mode of the air vent 12 on the stage body of combustion-supporting garden can be chosen in the Rotary-table bottom and arrange large aperture air vent (as about 5mm), and small-bore air vent (as about 3mm) is arranged on top; Large aperture air vent and small-bore air vent also can be alternately.On ground floor Rotary-table 5a, preferably arrange about 135 little air vents, 45 big air vents, preferably all arrange 45 air vents of having an appointment on the second layer Rotary-table 5b, can make combustion gasification more fully rationally like this.On the hearth body of burner hearth 4, preferably be furnished with 8-12 passage 13 (as shown in Figure 2) that communicates with the furnace bottom atmosphere, so more help the abundant combustion gasification of living beings.
