Description
Technical field
The present invention relates to a kind of biomass solid formed fuel, particularly a kind of biomass composite granular fuel that utilizes agricultural crop straw and wood materials manufacturing and preparation method and apparatus thereof.
Background technology
At present, along with the appearance of energy dilemma in the world wide and owing to use the serious environmental problem day by day that mineral fuel brought in a large number, the development and use to biomass energy are more and more paid attention in countries in the world.
Biomass granule fuel is a kind of mode of utilizing of biomass energy, and its raw materials for production are forestry " three surplus things " (wood machining residues, forest harvesting residuum, producing material residuum), various wooden tankage, wooden waste, agricultural crop straw (as maize straw, broomcorn straw, wheat stalk etc.) and shrub (as sea-buckthorn) etc.Production process is with the biomass material that quality is loose, energy density is little, through operations such as pulverizing, dryings, is processed into biomass granule fuel through ring mold pressing roll extrusion molding mode then.The epigranular of biomass granule fuel, unit intensity can reach 1-1.4g/cm
3, intensity increases, and transportation and storage are convenient, and combustionproperty is obviously improved, and burning back energy utilization rate can be brought up to more than 83%, does not have sulfur dioxide emissions, and the ashes after the burning still are the high-quality fertilizer material.
Plant material mainly contains Mierocrystalline cellulose, hemicellulose, lignin composition.Because lignin belongs to noncrystal, is a kind of thermal plastic high polymer material, do not have the fusing point of determining, but have glass transition temperature, and also higher.When temperature is 70-110 ℃ is to soften to have stickiness, the hemicellulose in the plant material, Mierocrystalline cellulose can be bonded to granular fuel in the pressure lower compression, and lignin plays a kind of effect of binding agent.
Raw material is in through pressure roller and ring model extrusion process, can be when making moulding to suitable temperature, in agitator, can select to feed steam, (gas is done to make the normal temperature raw material, water ratio 10%-16%) is warmed up to 60-80 ℃, add that raw material friction in pressure roller and ring intermode and ring nib produces heat, make raw material that mold temperature is about 100 ℃.
Different types of raw material, lignin, hemicellulose, content of cellulose difference.The content of lignin is 27%-32% (over dry raw material) in the timber, and lignin content is 14%-25% in the grass kind plant.
When making granular fuel, for the higher wood raw material of lignin content, if reach the softening temperature of lignin at mold temperature, then viscous deformation will take place in lignin, thereby raw fibre is bonded together closely, and keep set shape, granular fuel is after cooling, intensity increases, and can obtain the biomass granule fuel that combustionproperty is similar to timber; And for the lower grass agricultural crop straw raw material of lignin content, in the compressed moulding process, then need to add a spot of, just can make the particle after the compression keep fine and close structure and set shape such as inorganic, organic and fiber-like binding agents such as clay, starch, waste paper rivers.In stalk, add other matrix materials and not only increased the production cost of granular fuel, and also can long-living certain pollutent behind the particle burning.
In addition, because the calorific value of agricultural crop straw is lower than timber, so adopting agricultural crop straw makes to such an extent that the granular fuel calorific value is lower than wood substance grain, in order to improve stalk particle incendiary calorific value, reach certain calorific value requirement, sometimes the high additives of calorific value such as a certain amount of expense diesel oil, coal or carbon dust need be added at stalk, but so also pollutent can be produced.
Summary of the invention
The present invention is directed to the above-mentioned defective that exists in the existing stalk granular fuel production process, provide a kind of different biomass material to mix New-type fuel, its manufacture method and the production unit of making granular fuel and not needing to add any matrix material and high heating value additive.
Technical scheme of the present invention is: a kind of biomass composite granular fuel, with the low agricultural crop straw of lignin content and calorific value and lignin content and the higher wood materials of calorific value is raw material, and agricultural crop straw and wood materials are pulverized the back to form granular fuel than mixing granulation arbitrarily.
Another object of the present invention is to provide a kind of manufacture method of biomass composite granular fuel, with the lower agricultural crop straw of lignin content and calorific value and lignin content and the higher wood materials of calorific value is raw material, agricultural crop straw and wood materials are pulverized respectively, after the drying, carried out that batch mixing, steam are softening, moulding, cooling, packing make granular fuel; Concrete manufacture method is as follows:
(1) the blocking, pulverize of agricultural crop straw: agricultural crop straw is cut into the coarse fodder of 10mm ± 0.2mm by shear, and then is ground into the particle of granularity≤5mm by sander;
