Description
Technical field
The present invention relates to the technical field of utilizing unconventional feedstock production biomass compact fuel, particularly relate to and utilize rubber seed hull to prepare the biomass compact fuel processing method.
Background technology
As everyone knows, entered since 21st century, human society is faced with serious energy problem, and solving the problem of environmental pollution that causes in energy shortage and the energy development is the key of human kind sustainable development.Biomass compact fuel is a kind of of biomass energy.It has renewable and eco-friendly dual characteristics biomass energy, is considered to the important component part of following sustainable energy system.Biomass energy changes the unit weight of biomass by the curing molding technology, improves fuel value, has improved combustionproperty, makes it become solid, the hard-packed solid forming compact fuel of quality.The solid forming biomass compact fuel is converted into available energy (heat or electric power) by direct burning, is main one of mode of utilizing of biomass energy.
Biomass are various organic substances that occurring in nature has life to grow, and comprise animals and plants and microorganism.Can be used as the part that the energy is used by people in the biomass and be called biomass energy.Wherein the biomass solid compact fuel has the volatiles height, and carbon is active high, and sulphur, nitrogen content are low, the advantage that ash content is low.Existing mineral fuel attribute, the characteristics of can store again, transport, regenerate, changing are the less a kind of energy that is subjected to the natural condition restriction.From the angle analysis of life cycle, the biomass combustion release of carbon dioxide is not given carbon dioxide content increase in the atmosphere.Therefore, according to international agreement, this part carbonic acid gas is not made greenhouse gases and is handled.The Chinese government has included biomass energy in the extrusion position that ensures national development, the important measures of the technical progress of accelerating the material energy as sustainable development stably and energy-saving and emission-reduction, the renewable energy source that comprises biomass energy is the field that China energy is first developed.
Very abundant in China's biomass energy, many resources are utilized as yet well, herd the residuum overwhelming majority that industry such as pair produces in agricultural and become waste, become the environmental pressure of every profession and trade.And on the other hand, the conventional energy resources of China is in short supply to have had a strong impact on socioeconomic fast development, and the concentrated on a large scale use of fossil energy, has caused harm to existent environment of people.Country has issued the multi-section law for this reason, strengthen the development research of renewable energy technologies energetically.Biomass energy is occupied critical role as the fourth-largest Energy resources in renewable energy source.The shortage that the exploitation biomass energy both can have been replenished conventional energy resources also has great environmental benefit.Compare with other biological mass-energy source technology, the biomass compact fuel technology is easy realization of large-scale production and use more, and its degree easy to use can allow common people easily be easy to accept.So, utilize biomass compact fuel that wide development space and good market outlook are arranged.In numerous biomass energies, the rubber seed shell is a kind of precious resources that people can not forget.Provinces and regions kinds such as Hainan Province of China, Yunnan Province, Guangdong Province, Guangxi Zhuang Autonomous Region are implanted with nearly 13,000,000 mu rubber woods.Only just there is more than 600 ten thousand mu cultivated area in the Xishuangbanna in Yunnan, the annual rubber seed that can produce more than 30 ten thousand tons, these seeds contain abundant grease and protein, through the promotion energetically and the popularization of local scientific research institution and government department, have caused the interest and the concern of industrial community at present.Rubber seed will produce a large amount of rubber seed hulls in the process that is utilized, its ratio will account for 45 percent of gross weight.And rubber seed hull contains a large amount of xylogen (accounting for about 20%), Mierocrystalline cellulose (accounting for about 45%), hemicellulose (accounting for 14.5%), and hydrogen richness reaches 7 percent; Oxygen level reaches 36 percent.Lower heat value reaches 66 percent of mark coal calorific value (29.3MJ/kg) at 19.50MJ/kg behind its compression moulding fuel.Be to manufacture the splendid raw material of biomass energy compact fuel.But this " being misplaced local resource " suffered to treat coldly for a long time, wasted.Now along with people to the re-recognizing of biomass resource, the value of rubber seed and shell thereof more and more is much accounted of.Particularly the provinces and regions of China's establishing in large scale rubber all are the tropical rain forest areas, and ecotope is extremely responsive, environmental protection requirement is than higher, again away from solid fuel supply places such as coals, and the under-supply development that is restricting local economy of primary energy source.And on traditional habit, cut down trees and be fuel by cutting firewood, bring big pressure to ecotope.Utilizing rubber seed hull production to prepare biomass compact fuel and both can satisfy the industrial production and the people demand to the energy, can make waste utilize protection environment and ecology more again, is that part is suited measures to local conditions, and kills two birds with one stone, and benefits the cause of society.
The production of biomass compact fuel prepares cardinal principle: (heat or do not heat) under certain pressure effect, made loose originally, in small, broken bits, unbodied biomass material be compressed into bigger granular, block, the bar-shaped various shaped fuels of density.The contraction principle of biomass compact fuel can be divided into the deformation result of closely knit filling, surface deformation and destruction, three kinds of reasons of viscous deformation.It at first is closely knit filling, little, the loose raw material in small, broken bits of effect lower density in external force is subjected to displacement and rearranges at the mould endoparticle, variation has taken place in intergranular contact condition, change to line or face contact from point, line contact beginning, contact area increases gradually, until the filling of finishing the mould finite space, the unit weight of raw material increases, and has realized closely knit filling; Along with the increase of external pressure, primary particle produces recoverable deformation and because relative displacement causes surface deformation and destruction; After externally pressure further increases, the viscous deformation that is produced by stress is further dwindled intergranular voidage, density continues to increase, the increasing of the increase specific density of its contact area wanted big hundreds of even thousands of times, impel to produce complicated mechanical engagement and intermolecular bonding force (particularly having under the condition of cakingagent), this process is referred to as viscous deformation.
For not making the material rebound deformation after the compression, in compression, an amount of cakingagent must be arranged.Cakingagent can be produced by material itself in compression, also can add on demand.
Because China is vast in territory, raw material types is various, the imbalance of economic technology development in addition, the biomass compact fuel that various places produce also varies on the quality quality, and is very different.Subject matter is:
(1), think little of raw-material collection keeping, cause rotten loss of effective constituent in the raw material, reduced the combustion heat value of biomass compact fuel;
(2), in processing and forming technology, particularly in the bar moulding for improving degree of compactness and intensity, adopt high temperature, highly compressed technology mode, but brought problems such as energy consumption height, mechanical component wearing and tearing are big, the high easy burnt paste of product temperature, spontaneous combustion.This is the manufacturer of each biomass compact fuel, face and need the urgent problem that solves.
At the deficiency and the problem of above-mentioned existence, this patent proposes to have starting material the warehouse style keeping measure of strict demand; The interpolation cakingagent can play and cohere and lubrication in the compression moulding process, can solve the above problems effectively.
