Description
Technical field
It is applied to the present invention relates to the exploitation field of biomass energy, more particularly to one kind with biomass
The biomass moulding technique and the biomass moulding material as made from the technique of upgrading are carried out for raw material.
Background technology
With China's demand for energy increase rapidly and conventional fossil fuel increasingly depleted, coal
Will not occur within the following quite a long time as the principal status of public economy of China's production of energy and consumption
Sexually revise at all.At present, the utilization for coal is more based on burning, and coal is in combustion
The pollutants such as substantial amounts of dust, carbon monoxide, sulphur or nitrogen oxide can be discharged, ecological environment is caused
It is continuous worsening, cause increasingly serious environmental problem.Therefore, clean regenerative resource has been developed
So turn into the important channel for solving energy crisis and environmental pollution.
Biomass energy is that green plants converts solar energy into chemical energy and is stored in the energy inside biomass
Amount, i.e., using biomass as the form of energy of carrier, it directly or indirectly derives from the light of green plants
Cooperation is used, and can be converted into conventional solid-state, liquid and fuel gas, inexhaustible, nexhaustible,
It is a kind of regenerative resource, while being also a kind of unique reproducible carbon source.Also, biomass energy is also
With multi-functionals such as energy substitution, emission reduction environmental protection and promotion rural economys, therefore, from energy security
Set out with environmental protection, the exploitation to biomass energy turn into the war of current development regenerative resource
Omit emphasis.
However, because the short texture of biological energy raw material, distribution are scattered, space-consuming is big, as
Fuel has that energy density is small, directly burn the thermal efficiency is low, transport and storage cost,
Cause to be difficult to scale efficiently to utilize, economic benefit is poor, commodity energy is converted into as restriction biomass
The key factor in source.The biomass solid shaping technology researched and developed in recent years changes traditional biomass energy
Land use systems, highdensity shaped fuel is converted into by loose biomass, is directly burnt or as gas
Change, liquefy raw material, a kind of effective way developed as biomass energy, be also to substitute conventional energy
The effective ways in source.
Done for example, Chinese patent literature CN102776009A discloses a kind of biomass energy shaping, pyrolysis
Industrialization production charcoal, gas, oil, galvanic process are evaporated, is comprised the following steps：Raw material is crushed, removed
Sent into after dirt in granulator, be pressed into Φ 6-12 × 20-30 particle, particle to be formed is cooled to room temperature
After ± 3 DEG C, then it is 3-5% to be baked to moisture content；Under conditions of completely cutting off air or having a small amount of air,
Particle charcoal, gas and liquid are gone out by thermochemical conversion to the shaped granule after drying.Above-mentioned technology has
Effect realizes the curing molding of biomass material, by by shaped granule pyrogenation and carbonization, being converted into it
With the raw material of industry such as more high-grade high-grade fuel and pyrolkigneous liquid, wood tar, biomass is improved
Value.
But above-mentioned technology is needed after crushing, dust removal process, biomass could be pressed into granule
The particle in footpath so that the operation of biomass moulding technique is tediously long, crush after also increase the processing of material
Measure and be shaped to little particle and be also not easy to pile up and transport.In addition, above-mentioned technology is by shaped granule
Before pyrogenation and carbonization, also need to cool down it and drying and processing, by the moisture control of particle
In the range of a very little, not only cause the trivial operations of above-mentioned technique, it is often more important that increase
The energy consumption of technique.Therefore, the moulding process of biomass how is improved to overcome the upper of prior art presence
Defect is stated, the still unsolved technical barrier in this area is still.
The content of the invention
Present invention solves the technical problem that being to overcome the operation present in existing biomass moulding technique
Numerous and diverse, treating capacity is big, time-consuming, the defect of high energy consumption, so provide it is a kind of it is simple and efficient to handle,
The low biomass moulding technique of energy consumption and the biomass moulding material as made from the technique.
Therefore, the present invention realizes that the technical scheme of above-mentioned purpose is：
A kind of biomass moulding technique, comprises the following steps：
Biomass material is packed bundled, bundled materials are formed；
It is under conditions of 20-100 DEG C, 5-40MPa that the bundled materials are compressing, as biomass
Molding mass.
The water content of the biomass material is not more than 20wt%.
The biomass material is stalk and/or wood wastes.
The volume of the bundled materials is not less than 0.5m3。
Power is 50-70 DEG C, 15-25MPa under conditions of the compacting.
The ratio between density of the biomass moulding material and the bundled materials is (2-4)：1.
The biomass moulding material as made from above-mentioned biomass moulding technique.
The present invention carries out compression process using hydraulic test to above-mentioned bundled materials, according to used mould
Shape and size difference, the molding mass with arbitrary shape and size can be made.Preferably,
The shape and size of biomass moulding material produced by the present invention and the carbonization chamber of tamping coke furnace match.
The above-mentioned technical proposal of the present invention has the following advantages that：
1st, the biomass moulding technique that the present invention is provided, by the way that biomass material directly is packed into bundled,
And it is under given conditions that the bundled materials pressing one-time of gained is just plastic, being needed with prior art will be raw
Material, which crushes, can just be pressed into particulate matter after dedusting compares, technological operation of the invention is simple and efficient,
Material handling capacity is small, and the shape of bundled materials and molding mass is easily controllable, is easy to pile up and transports.
2nd, the biomass moulding material that the present invention is provided can be directly used as the raw material of process for upgrading, without again
Cooled down and drying and processing, be conducive to simplifying processing step, it is often more important that can be also greatly reduced whole
The energy consumption of body technology so that technique of the invention has the advantages that simple and efficient to handle, energy consumption is low.And
And, biomass moulding material of the invention can obtain the rough coal of appreciable amount through the upgrading processing under specified conditions
Gas, tar and carbon residue, it is of the invention compared with the calorific value produced by waiting quality biomass matter to be used as fuel
Biomass moulding material possesses higher economic benefit.
