Description
Technical field
The utility model relates to energy-saving equipment, particularly a kind of biomass direct-fired gasification furnace.
Background technology
Existing biomass half-gasification oven is divided into combustion chamber and vaporizer, for last. following structure, but all have certain defective.Show: one of which, combustion chamber openings is bigger, and secondary oxygen supply outlet is less.Cause like this secondary oxygen supply can not with the fully mixed burning of fuel gas on the vaporizer, thereby the phenomenon of smoldering appears, its two, secondary oxygen supply pipe is not adjacent vaporizer outer wall, but adjacent outer casing inner wall, caliber is also big inadequately.In use, the oxygen supply pipe heats up slower, and stack effect is not obvious, thereby causes secondary oxygen supply temperature low, and the oxygen-supplying amount wretched insufficiency is smoldered thereby make in the cooking stove use, also is prone to flame-out; Its three, vaporizer can not be totally-enclosed, do not possess the function of banking up a fire, after each cooking, residual fuel must let it exhaust voluntarily in the cooking stove, causes waste not energy-conservation like this.
The utility model content
The purpose of the utility model is to the prior art defective that insufficient over-emitting black exhaust, stove can not bank up a fire of burning, and a kind of over-emitting black exhaust not of fully burning is provided, possesses the biomass direct-fired gasification furnace of the function of banking up a fire.
The described biomass direct-fired gasification furnace of the utility model, it comprises shell and is installed in combustion chamber, vaporizer, the base in the shell; The lower end of said vaporizer is installed on the base, the upper end connects the combustion chamber; Said combustion chamber comprises inner cylinder and outer cylinder, and circular hole is offered on inner cylinder top, and outer cylinder outer wall bottom connects secondary and supports pipe, and secondary supports pipe near the vaporizer outer wall, passes base and atmosphere; Said vaporizer is the cylinder of upper end plate with cover, and the circular hole of diameter less than combustion chamber inner cylinder diameter offered at the cover plate center.
The outer top of said vaporizer cylinder is provided with charging aperture, and the below of charging aperture is provided with fire grate in the cylinder.
The ash discharge drawer is set on the said base.
Said shell upper end is provided with cover plate, and packing ring is set on the cover plate.
The port of said combustion chamber outer cylinder is provided with the end cap of annulus in the band, and interior annulus is enclosed within the inner cylinder; The outer wall top of combustion chamber outer cylinder is provided with firestopping ring.
The vaporizer top of the utility model can be sealed with steel plate, ash discharge drawer sealing can be used in the bottom, will directly burn and gasification, and combustion combines; The outer wall of the adjacent vaporizer of secondary oxygen supply pipe connects, and makes the temperature of secondary oxygen supply pipe raise soon, and stack effect is obvious, and combustion process is over-emitting black exhaust not, not flame-out, easy to operate, energy-conservation, low-carbon (LC), environmental protection; In addition, last residual fuel is banked up a fire through vaporizer after the carbonization, can be used for next cooking or heating, and energy-saving effect is obvious.
Description of drawings
Fig. 1 looks the sectional structure sketch map for the master of the utility model.
Fig. 2 is the A-A sketch map.
The specific embodiment
Like Fig. 1, shown in Figure 2, the utility model comprises shell 9 and is installed in combustion chamber 4, vaporizer 5, the base 10 in the shell 9, and the lower end of vaporizer 5 is installed on the base 10, the upper end connects combustion chamber 4; Combustion chamber 4 comprises inner cylinder 41 and outer cylinder 42; Circular hole 43 is offered on inner cylinder 41 tops; The port of outer cylinder 42 is provided with the end cap 44 of annulus in the band, and interior annulus is enclosed within the inner cylinder 41, and the bottom of outer cylinder 42 connects secondary and supports pipe 13, top that firestopping ring 3 is set; Secondary is supported pipe 13 adjacent vaporizer 5 outer walls, passes base 10 and is communicated with outside atmosphere; Vaporizer 5 comprises cylinder 51 and the cover plate 52 on it, the charging aperture 7 that the outer top of cylinder 51 is provided with, and the outer end of charging aperture 7 is provided with feed cap 6, and the below of charging apertures 7 is provided with fire grate 8 in the cylinder 51; The circular hole 53 of diameter less than combustion chamber 4 inner cylinders, 41 diameters offered at the center of cover plate 52; Shell 9 upper ends are provided with cover plate 2, and packing ring 1 is set on the cover plate 2; Ash discharge drawer 11 is set on the base 10.
Be placed on the packing ring 1 after earlier cooker being added suitable quantity of water during use, ash discharge drawer 11 is pulled out 1/3rd, join living beings in the vaporizer 5 through charging aperture 7 and light; Through burning about 10 minutes the time, can obviously see direct burning and gasification, and combustion and deposit, shut ash discharge drawer 11; Stay 2-3 millimeter crack, this moment, vaporizer 5 interior biomass fuels were in the anoxycausis state, under high temperature action; Can separate out imflammable gas continuously; When the high temperature imflammable gas makes progress through combustion chamber 4, produce continuous burning with the oxygen of coming in from secondary oxygen supply pipe 13, the outer top of shell 9 is provided with smoke evacuation pipeline 12.
After cooking is accomplished, when also having remaining fuel in the vaporizer 5, cover the circular hole 53 on vaporizer 5 cover plates 52 with steel plate, ash discharge drawer 11 is closed and can be banked up a fire to stove, with the residual fuel carbonization for using next time.
