Description
Technical field
The present invention relates to a kind of biomass fuel, relate in particular to a kind of compound type bamboo biomass granule fuel and preparation method thereof.
Background technology
Energy shortage and ecocrisis are the focuses that society is paid close attention to, and are also the bottlenecks of development of modern society economy.The fossil energy epoch of the earth are moved towards termination gradually, and the fossil energy situation of China is also very severe.Calculate with the current rate of economic development and energy consumption, the oil savings amount of China can be used approximately 15 years, available approximately 30 years of Sweet natural gas savings amount, available approximately 81 years of coal savings amount, available approximately 50 years of the savings amount of uranium.After decades, the fossil energy resource of China is depleted, and energy supply and demand is in short supply will restriction China's economy and social development, finds the task of top priority new, that renewable energy source has become China.Contrast fossil energy, biomass energy becomes the new force of energy industry gradually because of advantages such as it is renewable, aboundresources, eco-friendlies, in society Economic development, plays an important role.
In world's energy consumption, biomass energy consumption accounts for 14% left and right of energy total amount, particularly some under-developed areas, and biomass energy consumption accounts for the more than 60% of energy total amount.China is the big country of a biomass resource utilization, and various biomass resources are very abundant.Biological carbon is the product being formed through pyrolysis carbonization as timber and residuum thereof, agricultural crop straw, bamboo rattan plant by biomass material.Biological carbon has high energy density, and its combustion heat value and coal facies are worked as, but it has green, environmental protection and the advantage such as sustainable.Meanwhile, because it has very large specific surface area and porosity, surface adsorption ability is strong especially.And biological carbon also has conductivity, far infrared performance, negative ion effect and abundant trace element.These characteristics have determined that biological carbon has purposes very widely, comprise for water and purifying air shielding electromagnetic wave, deodorizing taste removal, fodder additives, soil improvement, medicines and health protection, daily necessities and articles for washing etc.The development research of biological carbon is a urgent important research topic, because it relates to several large problem in the urgent need to address that current China faces, as soil improvement, the loss that conserves water and soil, reduces greenhouse gas emissions etc.
Little about utilizing the information of bamboo wood production biomass granule fuel at present.But bamboo wood a kind of aboundresources that is China, have a very wide distribution, the biomass resource of fast growth, be the potential source biomolecule matter resource of the exploitation bamboo wood solid biomass energy.The domestic technology of preparing in biological carbon is generally to carry out under the condition of 450-600 ℃, has caused the height thermal destruction of chemical composition in biological material, not only need to consume more energy, and the combustion heat value of biological carbon also can significantly reduce.
Summary of the invention
Object of the present invention is just to provide one to address the above problem, and utilizes compound type bamboo biomass granule fuel that bamboo wood mixes with other biological matter resource and preparation method thereof.
To achieve these goals, the technical solution used in the present invention is: a kind of compound type bamboo biomass granule fuel, described biomass material is to be mixed by a certain percentage by bamboo wood material and non-bamboo biological matter resource, described bamboo wood material is to be mixed in any proportion by bamboo wood and bamboo surplus material of processing, concrete ratio must be determined according to the performance of material, could meet the performance requriements of product, biological organism or organic waste that described non-bamboo biological matter resource is reproducible non-bamboo wood;
As preferably, described bamboo wood material adopts a kind of bamboo wood and bamboo surplus material of processing or various bamboo materials and bamboo surplus material of processing to mix;
As preferably, described non-bamboo biological matter resource is one or more in agricultural biomass resource, forestry biomass resource, waterplant, human and animal excreta and domestic organic garbage, city organic waste and industrial organic wastes;
As preferably, the length of described compound type bamboo biomass granule fuel is at 3-50mm, diameter is less than 12% at 3-20mm, water ratio, ash value lower than 10%, combustion heat value should be greater than 17500J/g.
A kind of compound type bamboo biomass granule fuel preparation method, method steps is as follows,
A. adopt biological carbon carbonization at low temperature technology, biomass material is carried out to carbonization under carbonization temperature 200-300 ℃ and oxygen barrier condition; The typical feature of biological material is that moisture and volatile component are high, and these materials cause the combustion processes of biological material unstable, is difficult to control the process of its burning.And these materials need to absorb heat in the process of burning degrades, and causes material combustion calorific value to reduce, so adopted carbonization at low temperature technology, carbonization temperature can not be too high, can cause the thermal destruction of biological material composition.Meanwhile, carbonization under the condition of oxygen barrier, prevent that material from burning in the process of carbonization.After carbonization, the moisture of biological material and volatile matter reduce, and combustion heat value increases, and ignition temperature improves, and combustion stability strengthens, and can carry out mixed firing with coal; And after carbonizing treatment, the intensity of material decreases, cause saving a lot of energy in the material disintegrating process in later stage, reduce cost;
B. must be through pulverizing by described biomass material, but biomass material particulate state or fibrous material after described pulverizing;
C. choose the biomass material of particle diameter below 10mm through sifting machine;
D. the bamboo wood material after carbonization and non-bamboo biological matter resource are mixed in proportion;
E. described biomass material is through conditioning, and after damping, its water ratio is below 25%;
F. by biomass material, through biomass granule forming machine, compacting forms again, then packs.
Compared with prior art, the invention has the advantages that: the present invention is not in the situation that adding any Chemical Felter, utilize bamboo wood material produce to go out a kind of energy-saving and environmental protection, the compound type bamboo biomass solid fuel that thermal value is high, ash oontent is low, objectionable impurities is low.In compound type bamboo biomass granule fuel moulding process, do not add any chemicals and toxic ingredient.When this product uses, thermal value is high, and ash content is low, meets environmental protection requirement, is the same fluid fuel of biomass that China has commercial development potentiality, has good economic benefit, social benefit and environmental benefit.
