Technical field
The invention belongs to biomass fuel technical fields, and in particular to a kind of biomass new energy fuel and its preparation side Method.
Background technique
Biomass fuel: referring to biological material burning as fuel, generally mainly agriculture and forestry organic waste material, the main distinction In fossil fuel.In current national policy and environmental protection standard, direct biomass burning belongs to high pollution fuel, only in rural area Brick kitchen range in use, do not allow to use in city.The application of biomass fuel, practical is mainly biomass molding fuel, is Various moldings are made (such as blocky, graininess by techniques such as crushing, mixing, extruding, drying using agricultural waste as raw material Deng), a kind of Novel clean-fuel that can directly burn.
Chinese patent literature " a kind of biomass triplet-powder solid fuel and its production technology (patent No.: ZL200910166760.9 a kind of biomass triplet-powder solid fuel and its production technology and preparation method thereof, the combustion) " are disclosed Material presses stalk 65-75%, sawdust 15-25%, shell skin 5-15%, oxygen using stalk, sawdust, shell skin, calcium oxide as raw material The weight proportion for changing calcium 0.5-2% is mixed;Smokeless when burning, the pernicious gases such as carbon dioxide, sulfur dioxide can reach substantially To zero-emission, the volume of remaining ashes only has 1/10th of volume of fuel, and can make biomass fertilizers use;The fuel can replace In generation, is coal-fired, as the main fuel of Industrial Boiler, to efficiently solve problem of environmental pollution, but its physical property and the combustion heat Value need to be improved.
Summary of the invention
The object of the present invention is to provide a kind of biomass new energy fuels and preparation method thereof, to solve in patent document On the basis of " a kind of biomass triplet-powder solid fuel and its production technology (patent No.: ZL200910166760.9) " is disclosed, Optimize component, dosage, the method etc. of biomass new energy fuel, improves the physical property and the combustion heat of biomass new energy fuel Value.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of biomass new energy fuel, raw material include: stalk, sawdust, shell skin, dehydrating agent, calcium oxide, beans steroid Alcohol, hydroxy silicon oil, epoxidized soybean oil;The stigmasterol, hydroxy silicon oil, epoxidized soybean oil weight ratio are (4-6): (5-10): (1-3)。
Further, the stigmasterol, hydroxy silicon oil, the weight ratio of epoxidized soybean oil are 5:7.5:2.
Further, the biomass new energy fuel is as unit of parts by weight, including following raw material: stalk 650-750 Part, 150-250 parts of sawdust, 50-100 parts of shell skin, 10-20 parts of calcium oxide, 4-6 parts of stigmasterol, 5-10 parts of hydroxy silicon oil, epoxy 1-3 parts of soybean oil.
Further, the biomass new energy fuel is as unit of parts by weight, including following raw material: 700 parts of stalk, wood Consider 200 parts, 75 parts of shell skin, 15 parts of calcium oxide, 5 parts of stigmasterol, 7.5 parts of hydroxy silicon oil, 2 parts of epoxidized soybean oil to be worth doing.
Further, the stalk, sawdust, the mesh number of shell skin are 20-40 mesh.
Further, the dehydrating agent is fiber desiccant.
Further, the biomass new energy fuel is cylindrical fuel, diameter 6-20mm, length 20-60mm.
A kind of preparation method according to above-mentioned biomass new energy fuel, comprising the following steps: (1) first by the straw of selection Three kinds of stalk, sawdust, shell skin raw materials crush respectively, screen out soil, grains of sand harmful components;(2) it is matched by formulation weight, by straw Stalk, sawdust, shell skin, calcium oxide, dehydrating agent uniformly mix;(3) mixed-powder is packed into the high-order hopper of pellet press, and Setting form is squeezed into respectively at normal temperature by multiple granulation heads of extruder.
The invention has the following advantages:
(1) as the data of embodiment 1-3 and comparative example 5 as it can be seen that the combustion of biomass new energy fuel made from embodiment 1-3 It heats value and physical property significant effect is higher than the combustion heat value and physical property of biomass new energy fuel made from comparative example 5 Effect;Simultaneously by the data of embodiment 1-3 as it can be seen that embodiment 1 is optimum embodiment.
(2) by embodiment 1 and the data of comparative example 1-4 as it can be seen that stigmasterol, hydroxy silicon oil, epoxidized soybean oil are given birth in production Play synergistic effect in substance new energy fuel, collaboration improves the combustion heat value of biomass new energy fuel and physical Energy;This is:
Original formulation uses the main body comburant of stalk, sawdust, shell skin as biomass combustion, and calcium oxide is as desulfuration Agent and antichlor, but only with said components, can not achieve better combustion heat value and physical property, thus the present invention also adds Stigmasterol, hydroxy silicon oil, epoxidized soybean oil are added.
Stigmasterol has high carbohydrate content, can increase combustion heat value, while it reduces moisture in biology with water imbibition The content of matter promotes burning inflammability, while good film forming and ductility, has to biomass cells good affine Property, fully dispersed each biomass components, balanced each component physical property, can enhance made of fuel whole impact strength and Crush resistance;Hydroxy silicon oil is active hydroxyl, can further improve the Fundamental Physical Properties of material, in combustion It is decomposed to form micro- silicon-carbon intermediate of Nano grade, the carbon black that stigmasterol is decomposed to form in combustion process can be adsorbed onto micro- silicon-carbon On intermediate, to improve dispersibility, so as to come into full contact with promotion full combustion with air, combustion heat value is improved;Epoxy Soybean oil has excellent water resistance, can be sufficiently mixed with each biomass components, and it is good mechanical strong to assign biomass fuel Degree, while the terminal hydroxy group of its epoxy group and hydroxy silicon oil has hydrogen bond action, improves the dispersibility of hydroxy silicon oil, and pass through two The combination of person further promotes the integral strength of biomass fuel in biomass fuel, and stigmasterol has certain surface-active Agent effect can improve the viscosity of hydroxy silicon oil and epoxidized soybean oil, and flash carbonization collapses in combustion, be formed porous Road promotes the entrance of oxygen, the decomposition rate of hydroxy silicon oil and the full combustion of stigmasterol is improved, to improve the combustion heat Value.
(3) by the data of comparative example 6-8 as it can be seen that stigmasterol, hydroxy silicon oil, the weight ratio of epoxidized soybean oil is not at (4-6): (5-10): when in (1-3) range, the combustion heat value and physical property effect and embodiment 1- of biomass new energy fuel obtained 3 numerical value is very different, suitable with the numerical value of the prior art (comparative example 5) much smaller than the numerical value of embodiment 1-3.Beans of the present invention Sterol, hydroxy silicon oil, epoxidized soybean oil pass through when control produces biomass new energy fuel as reinforcement system, embodiment 1-3 Stigmasterol, hydroxy silicon oil are added, the weight ratio of epoxidized soybean oil is (4-6): (5-10): (1-3), is realized sharp in reinforcement system There is high carbohydrate content with stigmasterol, combustion heat value, balanced each component physical property can be increased;Hydroxy silicon oil is in combustion process In be decomposed to form micro- silicon-carbon intermediate of Nano grade, the carbon black that stigmasterol is decomposed to form in combustion process, can be adsorbed onto it is micro- On silicon-carbon intermediate, promotion full combustion can be come into full contact with air, improve combustion heat value;Epoxidized soybean oil improves hydroxyl silicon The dispersibility of oil, flash carbonization collapses stigmasterol in combustion, forms multi-pore channel, promotes the entrance of oxygen, improves hydroxyl The decomposition rate of silicone oil and the full combustion of stigmasterol, so that combustion heat value is improved, to improve the combustion of biomass new energy The combustion heat value and physical property of material.
