Description
Technical field
The present invention relates to machine-made carbon processing technique field, especially a kind of machine-made carbon carbonizes decoking technique.
Background technology
Charcoal (machine-made charcoal) also known as machine-made carbon, it is firewood stick, artificial carbon, regenerated carbon, smokeless clear
Clean charcoal, be with woody debris' extrusion process at carbonaceous club derived from Japan, product claims " wooden power lose fall forward ", by Chinese platform
Gulf is passed to China's Mainland stick carbon feedstocks and derives from a wealth of sources, rice husk, peanut shell, boll hull, corncob, cornstalk, sorghum stalk, beans stalk, saw
End, sawdust, wood shavings, loose grain shell, cocoanut shell etc. all can be used as raw material production stick charcoal, be best with sawdust, wood shavings, bamboo scraps, rice husk.
Stick charcoal extensive market.Restaurant is used as barbecue charcoal, and stick charcoal density is 3 times of charcoal or more, and burning is smokeless, and industrially, stick charcoal is used
In production carbn disulfide and smelting iron and steel.Stick charcoal also serves as the supplement fuel of boiler, its density is close with coal facies, and calorific value is
5500-7000 kilocalories/kg, but ash is significantly lower than coal.
Charcoal main feature：Density is big, and calorific value is high, smokeless, tasteless, pollution-free, do not explode, is inflammable, is in the world
Generally acknowledged green product, tradition are most machine-made carbons, need to carry out decoking charing, then could be used, however pass
The charing decoking process of system is relatively complicated, and not environmentally friendly enough, for these problems, herein it is proposed that a kind of machine-made carbon charcoal
Change decoking technique.
Invention content
The present invention is to solve above-mentioned technical deficiency, using modified technical solution, a kind of machine-made carbon charing decoking technique, and tool

C02,H2SO2, variation takes place in the chemical composition of raw material, and the temperature that different material starts pyrolysis is different, the low object of degree of metamorphism
It is relatively low that material starts pyrolysis temperature；
S3, carbonization stage temperature is at 300-600 DEG C, and based on polycondensation and pyrolysis, volatile matter is largely precipitated in raw material,
The products almost all such as tar, methanol, the ethylene that carbonization process is precipitated generate in this stage, gradually soft in this stage material
Change, melting, form the gel of gas, liquid, solid three-phase coexistence, then is changed into semicoke through processes such as flowing, polycondensation, solidifications, it is needle-shaped
Semicoke or blocky semicoke, that is, complete charing processing.
As present invention further optimization mode, in step a, raw material warp that sawdust curing molding need to be Jing Guo initial gross separation
It crosses screw conveyor to be admitted in air-flowing type roller drier, the hot-air that raw material is sent in hot-blast stove in drying machine dries
Dry, while raw material is carried out impurity separation again, smaller stone and bark are isolated out, raw material after drying and produced
Steam siphoned away by wind turbine, be admitted in cyclone separator through piping, carry out steam and siccative separation, by the wood of drying
Humidity is considered to be worth doing 4% -6%, is separated from wet air by the effect of gravity, dry sawdust in cyclone separator
Hopper is fallen into, is sent directly into molding machine by feed screw in hopper and carries out curing molding, by this procedure, sawdust quilt
It is formed with the sawdust stick of regular shape, size is usually 40cm × 5.1cm × 5.1cm, and there is hole at center.
As present invention further optimization mode, in step b, charing tail gas needs just be directly discharged by processing big
Gas is purified using burning method, and burning method is to make charing tail gas into people's sedimentation furnace, under 800-950 DEG C of hot conditions simultaneously
It fully burns in the atmosphere for having excess air, fuel gas and harmful substance is all burnt into CO2After be discharged into air, incinerator
The heat that middle burning generates can be carried out recycling by waste heat boiler and generate steam.
Entirety process of the present invention is simplified, and raw material use sawdust, this method small investment easy to operate and processed
The environmentally harmful substance of the overwhelming majority can be removed in journey, while can generate the required steam of production process of activated carbon,
Whole more science and environmental protection, suitable for batch machining.
