Description
Technical field
The invention belongs to B27M1/06：Pass through burning or the technical field of coking timber.
Background technology
Timber is mainly made up of cellulose, hemicellulose, and cellulose plays skeleton function in wood cell wall, and it is chemically
Matter and supramolecular structure have a major impact to the intensity of timber.Hydroxyl and hydrone in cellulose can also form hydrogen bond, different
Existing hydrogen bond directly affects moisture absorption and the desorption process of timber between the hydroxyl at position.Substantial amounts of hydrogen bond can improve timber
Intensity, reduce hygroscopicity, reduce chemical reactivity etc., and the hygroscopicity of cellulose directly influences spacing dimensional stability
And intensity.Timber reduces the concentration of hydroxyl after carbonization technique, and complicated change occurs for chemical constitution, so that timber
Hygroscopicity reduce, dimensional stability improve.Hemicellulose is the material being coupled in cell membrane with close membrane, rises to bond and makees
With being base matter, hemicellulose hygroscopicity is strong, poor heat resistance, easily hydrolysis, is prone to become under extraneous conditioning
Change, be the component that hygroscopicity is maximum in timber, be timber is produced moisture expantion, one of the factor of strain cracking, pass through carbonization
Hemicellulose can be destroyed, thus the hygroscopicity of timber can be reduced, reduced the expansion and contraction of timber, improve carbide wood
Dimensional stability.
Current Wood carbonization technology is all by the use of high-temperature water vapor as medium and protection medium is directly heated, to some
The high special timber of the moisture content such as drying stage before carbonization such as eucalyptus, birch, due to the effect of water vapour and oxygen, in wood
Substantial amounts of mould spot can be produced in material, have impact on the presentation quality of timber after carbonization, and the temperature in carbonization is higher, such as
Fruit oxygen concentration is too high, easily on fire.
The content of the invention
It is hidden to solve safety on fire to be present in existing carbonization technology the invention is intended to provide a kind of carbonization technique of timber
The problem of suffering from.
A kind of technique of Wood carbonization in this programme, comprises the following steps：
The first step, cutting, by cutting machine by timber cut growth bar shaped；
Second step, carbonization case is built, choose a cylindrical casing as carbonization case, one electricity of casing top connection
Machine, the bottom for the case that is carbonized are provided with heating passage, and the top of carbonization case is provided with sucker, is set in the bottom of carbonization case and is placed with collection

One end of nearly gas flow channel is provided with fuel gas buring mouth, is connected between combustion chamber and heating passage by airway tube；
3rd step, it is powered, make aluminium foil positively charged with electrostatic generator, and water-absorbing resin band is born with electrostatic generator
Electricity, with water-absorbing resin of the aluminium foil absorption with negative electricity with positive electricity；
4th step, timber is wrapped up, the aluminium foil for being adsorbed with water-absorbing resin is wrapped on timber, aluminium foil open-ended, makes water suction
Resin is affixed on timber outer wall；
5th step, timber are fixed, and the timber for being wrapped with aluminium foil is fixed with the sucker suction on carbonization case top；
6th step, carbonization, motor make carbonization case uniform rotation, the air mixture in combustion chamber are passed through into heating passage
It is interior, and staged continuous warming method is used, the temperature being carbonized in case is first warming up to 130 DEG C, is carbonized after 1h, then be warming up to
250 DEG C, then keep 250 DEG C of constant temperature carbonizations；
7th step, ventilation, hot blast is passed through into carbonization case from the top for the case that is carbonized.
The working principle and beneficial effect of above-mentioned technical proposal is：1. aluminium foil has the performance of fire prevention and heat absorption, by aluminium foil
The outside of timber is wrapped in, can prevent that the oxygen concentration in carbonization case is too high and on fire, aluminium foil can prevent fires, and prevent timber from firing
Burn.
2. aluminium foil can absorb heat, the hot gas in carbonization case can be absorbed, and hot gas is passed into timber, make timber uniformly by
Heat, ensure that Wood carbonization is more uniform, be advantageous to improve the preservation of timber against decay performance and insect prevention performance.
3. timber is lived with sucker suction, timber is circumferentially arranged, can prevent timber from stacking uneven heating, further
Improve the uniformity of Wood carbonization.
4. because the outside for the case that is carbonized is provided with gas flow channel, after driving carbonization case to rotate using motor, make mixing
Combustion gas is sent into burning Indoor Combustion through Gas Pipe, and the carbon dioxide generated after burning enters in gas flow channel by airway tube
Heating carbonization case, gas first pass around hot air discharge pipe, the flowing velocity of gas can be reduced by the process of hot air discharge pipe,
The bottom of carbonization case is heated first, hot gas is gradually communicated up, during fuel gas transmission, by the flame size for controlling burner
Regulation carbonization the temperature inside the box, in carbonisation, carbonization case, which rotates, can make timber uniform rotation, further improve Wood carbonization
Uniformity.
After 5. timber is heated, the vapor of wood internal can be distributed outwards, so as to be absorbed by water-absorbing resin, so that water suction
Resin expansion, increase the gap between timber and aluminium foil, so that aluminium foil is gradually spread out.
6. to hot blast is passed through in carbonization case, the aluminium foil strutted by water-absorbing resin is blown off, aluminium foil is fallen into collecting box.
7. as wood internal vapor gradually evaporates, suction cup interior progresses into air, so that timber is gradually from suction
Depart from disk, eventually fall into collecting box, without being manually collected, the efficiency of Wood carbonization is greatly improved.Using the method,
It can not only prevent that carbonization the temperature inside the box is too high and on fire, and the carbonization efficiency of timber can be greatly improved, improve wood
The being heated evenly property of material.
Prioritization scheme one, as the further optimization to base case, the carbonization case is made of copper.Copper thermal conductivity is good,
And the cost performance of copper is higher.
Prioritization scheme two, as the further optimization to prioritization scheme one, the outside of the carbonization case is provided with one layer of heat preservation
Material.The outside of carbonization case is provided with insulation material, can keep the temperature inside carbonization case.
Prioritization scheme three, as the further optimization to prioritization scheme two, the hot air discharge pipe is spiral shape.Hot gas is arranged
The flowing velocity of gas can further be reduced for spiral shape by putting pipe, ensure that the bottom of carbonization case is heated abundant, so as to ensure wood
The lower section of material can be carbonized fully.
Prioritization scheme four, as the further optimization to prioritization scheme three, the sucker uses vacuum cup.Vacuum cup
Adsorptivity it is more preferable, it is more long can to ensure that timber can be heated.
Prioritization scheme five, as the further optimization to prioritization scheme four, in the 7th step, hot blast is passed through in carbonization case
Afterwards, then into carbonization case it is passed through 100 DEG C of saturated steam.Using 100 DEG C of saturated steams to the timber after carbonization treatment
Damping moisture regain processing is carried out, the sheet material of overdrying can be fast and effectively moistened, so that following process process is smoothed out.
