Specific implementation mode
With reference to specific embodiment, invention is further described in detail.
Embodiment：
As shown in Figure 1 to Figure 3, the present invention be a kind of biomass cracking carbide furnace, including horizontal furnace body 1, be set to furnace body 1
The ignition mechanism 2 of lower section, the feed cylinder 3 set on the inner cavity of furnace body 1, the feed hopper 4 of connection 3 import of feed cylinder, connection feed cylinder 3
The discharge nozzle 5 of outlet and the chimney (the first chimney 6 and the second chimney 7) above furnace body 1, furnace body 1 is in face dynamo exploder
The position of structure 2 is equipped with the gap entered for air, is equipped with a screw feeding axis 31 in feed cylinder 3, the top of feed cylinder 3 is equipped with
The port 32 of the inner cavity of several connection furnace bodies 1.It is inside and outside two layers that feed cylinder 3, which divides furnace body 1, the biomass cracking that internal layer occurs
The endothermic reaction that biomass material is cracked to form to coke and inflammable substance under anaerobic environment, outer layer happens is that
The exothermic reaction of inflammable substance burning.In real work, the heat that outer reaction is released can be than the heat of internal layer reactive absorption
It is more, so maintaining the progress of two reactions that can not lean in addition input heat.Specific work process is：Biomass material from into
Hopper 4 is sent into feed cylinder 3, is conveyed forward under the thrust of swivel feeding axis 31；Reaction at the beginning ignition mechanism 2 to furnace body 1 into
Row heat supply causes cracking and starts, and fuel gas constantly will be discharged into furnace body by the solid matter in feed cylinder 3 from port 32
In 1, fuel gas is mixed with the air come in from gap and is then lighted, and after waiting flameholdings, ignition mechanism 2 can not have to consumption
Fuel, the burning of fuel gas can maintain the energy consumption of high temperature and offer cracking in furnace body 1 automatically.Therefore the present invention can be
Cracking need not be heated into local continuous production coke after stablizing, and have good economic benefit.
As shown in Figure 1 to Figure 3, furnace body 1 is divided into hothouse 11, preliminary thermal cracking room 12, complete 13 and of thermal cracking room
Transition cooling chamber 14, hothouse 11 are equipped with the first chimney 6, and complete thermal cracking room 13 is equipped with the second chimney 7, ignition mechanism 2
Set on the lower section of transition cooling chamber 14.Ignition mechanism 2 heats up to transition cooling chamber 14, is closed after initiation reaction, mistake after stablizing
Cooling chamber 14 is crossed to burn general, temperature is relatively low by gap air inlet；There are chimney in hothouse 11 and complete thermal cracking room 13
As gas vent, burning is more abundant, and temperature is higher；Preliminary thermal cracking room 12 can only introduce air, burning from chamber is closed on
It is less.It is to realize that the reasonable distribution of 1 temperature range of furnace body, the heating of hothouse 11 can save the dry of biomass material in this way
Dry requirement；From preliminary thermal cracking room 12 to 14 temperature from low to high of transition cooling chamber, fully reaction was not only met and had required, but also coke can be made
Charcoal comes out temperature reduction, and discharging is avoided to burn.
As shown in Figures 2 and 3, the root of the first chimney 6 is equipped with first switch device 61, and the root of the second chimney 7 is equipped with
Second switch device 71.The burning in furnace body 1 of the imflammable gas of cracking out, which can discharge heat, causes 1 temperature of furnace body to increase,
If burning velocity is uncontrolled to may result in the fusing of furnace body 1, cause the accident.First switch device 61 and second switch device 71
The flow that air in furnace body 1 can be controlled keeps combustion reaction abundant, reduces dense smoke or toxic gas generates.
As shown in Fig. 2, the outlet height of furnace body 1 is less than entrance height, the inclination angle of furnace body 1 is 1 °.Inclination angle is arranged in furnace body 1
It can be conducive to solid biomass material to spread toward front toward rear portion conveying and hot gas.Inclination angle is less just avoided that equipment is turned over
.
As shown in Fig. 1, Fig. 3 and Fig. 5, the lower part of discharge nozzle 5 connects an elevator 8, and elevator 8 is close to discharge nozzle 5
One end is less than one end far from discharge nozzle 5.The height-limited outlet height in feed cylinder 3 of discharge nozzle 5, before furnace body 1 after height
5 position of discharge nozzle can be lower in the case of low, then the discharge space of coke only understands smaller.Coke can be promoted and be arrived by elevator 8
Eminence, it might even be possible to be sent directly into haulage vehicle.
As shown in figure 5, screw feeding axis 31 includes axis body 311 and the flight 312 around axis body 311.Because of burning master
It is happened at port 32, flame is upward, so the temperature on 1 same position top of furnace body is often apparently higher than lower part.Spiral
On the one hand 312 mode of movement of piece plays progradation to material, on the other hand can stir material, realizes uniform heated.
The outer diameter of axis body 311 is smaller 130-150mm than the internal diameter of feed cylinder 3.Fuel gas in 3 outer combustion heat release of feed cylinder,
Heat will be conducted by the barrel of feed cylinder 3 toward internally positioned material, thickness between empirical discovery axis body 311 and feed cylinder 3
70 ± 5mm or so heat transfers can be more abundant, can guarantee reaction ratio so more thoroughly.
The outer diameter of axis body 311 is 50-70mm.In the case where 311 outer wall of axis body and feed cylinder 3 inner wall distance determine, axis
311 outer diameter of body is bigger, and conveying section is bigger, and theoretic production efficiency is higher；But if material send too fast, exothermic heat of reaction
More acutely it will increase control difficulty, empirical discovery axis body 311 takes outer diameter 50-70mm relatively more reasonable.
As shown in Fig. 2, the inlet side of port 32 toward feeding cylinder 3 tilts.Biomass material is often that stalk etc. is elongated
The plant material of item, port 32 are then the conveying direction along material toward outlet-inclined impeller vane, and raw material more easily propagates through port 32
It falls in furnace body 1, material is just burned without thermal cracking at this time, can bring prodigious waste.Port is set toward import
Side tilts and is just avoided that this problem.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
