Description
Technical field
The present invention relates to biomass fermentation electrical domain, refer in particular to a kind of Biomass Gasification And Power Generation System.
Background technology
Biomass are organism that plant is generated by photosynthesis, comprise plant, animal excrements, rubbish and organic waste water etc., are the carriers of biomass energy, are that one can store and transportable renewable energy source.Angle is chemically seen, the composition of biomass is C-H compounds.
From environmental benefit, biomass are utilized to realize CO
2the discharge of zero, fundamentally solves the Greenhouse effect problem that energy consumption brings.Day by day serious along with Global Environmental Problems, people's major concern be that biomass energy is to minimizing CO
2effect in discharge, add that development fast-growing energy crop is conducive to improving the ecological environment, objectionable impurities can not be left over or change the natural eubiosis, to the long term growth of the mankind from now on and living environment significant, so a lot of country mostly develops biomass energy utilization technologies as a kind of important WeiLai Technology in the world, the research of biomass energy is more and more paid attention to.
The biomass energy of China is very abundant, now annual straw amount about about 700,000,000 tons, is equivalent to 4 ~ 500,000,000 tons of mark coals.Bavin firewood and forestry waste quantity are also very large, and forestry waste (not comprising charcoal firewood woods), about reaches 3700m every year
3, be equivalent to 2,000 ten thousand tons of mark coals.If consider increasing domestic refuse and mud, the other biological matter resources such as fowl and animal excrement, the annual biomass resource of China reaches more than 600,000,000 tons of mark coals, deduct a part and do other raw materials, the biomass resource that can be developed as the energy reaches more than 300,000,000 tons ton of mark coal, and along with development that is agriculture and forestry, particularly along with the develop and spread of fast-growing charcoal firewood woods, the biomass resource of China will get more and more, and have very large development and utilization potentiality.
Biomass energy is a kind of desirable renewable energy source, its wide material sources, has a large amount of industry, agricultural and forest waste output every year.Even if be not used to produce the energy, the process of these wastes is also troubling thing.When biomass are as fuel, the amount of carbon dioxide of discharging when the amount of carbon dioxide due to biomass needs when growing is equivalent to its burning, is thus similar to zero to the clean quantity discharged of the carbonic acid gas of air.And the content of sulphur is extremely low in biomass, nonsulfide discharge substantially.So utilize the biomass energy as an alternative, to environmental protect, reducing carbon dioxide content in air thus reducing " Greenhouse effect " has great benefit.Therefore, using the substitute energy of biomass as fossil oil, just can provide a kind of everyway can received renewable energy source to society.Developing Biomass is the green energy resource transformation technology of raw material, meets this theme of human social.
Up to now, the preferred approach of biomass utilization is gasification, produces combustion gas by gasification, then obtains heat energy by the secondary combustion of combustion gas.Current biomass gasification technology obtains fast development, enters the practical stage, but biological fuel gas generation technology also rests on experimental stage, and domestic at present also do not have gratifying industrialization technology.Accelerate research and development Biomass Gasification Power Generation Technology, meeting national policy, is the good job of benefiting the nation and the people.
Biomass gasification technology be 20 the end of the centurys occur utilize biomass as a kind of new technology of the energy, there has been so far and develop faster.A lot of researchist has carried out different technical study in this field.Especially in recent years a lot of technician in Europe has carried out large quantifier elimination to Biomass Gasification Power Generation Technology, and achieves goodish achievement.
Middle-size and small-size Biomass Gasification Power Generation Technology is ripe in developed country, but due to small scale, process is complicated, and cost and running cost are all higher, are difficult to into people market in developing country.
Chinese Regional is wide, and biomass resource enriches, and power supply situation varies, Biomass Gasification & Power Generation has good life condition and development space, the Biomass Gasification Power Generation Technology of middle and small scale has less investment, the feature that handiness is good, is one of technology having potential value most.Greatly developing in China superiority and the economy that Biomass Gasification Power Generation Technology can embody this technology to greatest extent, is also solve China's straw from village to burn one of effective ways of problem.
But China is lower in the research level in biomass weather elelctrochemical power generation field at present, this also imply that a kind of well development prospect.
Biomass Gasification & Power Generation is combustible gas Wood Adhesives from Biomass, and recycling combustible gas promotes the process that fuel gas generation equipment carries out generating electricity.It can solve biomass and be difficult to burn and the shortcoming of distribution dispersion, can give full play to again fuel gas generation technical equipment compact and pollute few advantage.
The chemical process of gasifying biomass: the chemical process in vapourizing furnace mainly comprises combustion reactions, pyrolysis and reduction reaction.After biomass material enters vapourizing furnace, part and oxygen combustion, heat needed for thermolysis is provided, there is pyrolysis under anoxic conditions in major part biomass, separate out fugitive constituent and coke, fugitive constituent stops and secondary reaction occurs in high temperature reaction zone, makes tar be cracked into gas further, simultaneously between gas and coke, between gas and gas, there is reduction reaction further.Finally, tar and gas-carrying portion fine particle coke, the dust of gas phase enter gas-purification treater, are reached the requirement of oil engine by the combustion gas after purification.
Gasifying electricity generation process comprises three aspects: one is gasifying biomass, and solid biomass is converted into geseous fuel; Two is gas sweetenings, and gasification combustion gas out, all with certain impurity, comprises ash, moisture and tar etc., through purification system, impurity need be removed, to ensure the normal operation of fuel gas generation equipment; Three is fuel gas generations, utilizes internal combustion turbine or gas internal-combustion engine to generate electricity.
Biomass Gasification Power Generation Technology is the unique way being different from other renewable energy sources in biomass utilization, there are three aspect features: one is that technology has sufficient handiness, because Biomass Gasification & Power Generation can adopt oil engine, also internal combustion turbine can be adopted, even in conjunction with waste heat boiler and steam generating system, so Biomass Gasification & Power Generation can select suitable generating set according to the size of scale, ensure there is rational generating efficiency under any scale.The flexible performance of this technology meets the feature of biomass dispersion utilization well; Two is have good cleanliness, and biomass itself belong to renewable energy source, effectively can reduce CO
2, SO
2deng the discharge of obnoxious flavour.And the growing amount of gasification NOx is little, so can the discharge of effective control NOx; Three is economy, the handiness of Biomass Gasification Power Generation Technology, the economy that this technology is effectively good on small scale where can be ensured, fuel gas generation process is simple simultaneously, facility compact, also makes Biomass Gasification Power Generation Technology less than other renewable energy power generation technological investments, so generally speaking, Biomass Gasification Power Generation Technology is generation technology most economical in all renewable energy technologies, and comprehensive cost of electricity-generating is lower than the power generation level of small-sized conventional energy resources.
Current biomass gasifying electricity generation Problems existing:
One, ash process problem.Biomass Gasification & Power Generation except require viable economically except, its main purpose be process refuse.Because existing middle-size and small-size Biomass Gasification & Power Generation unit efficiency is not high, retain a small amount of carbon in ash, the ash therefore produced after gasifying biomass needs process further.
Two, gas sweetening.Oil handling of focusing in existing gasifying electricity generation unit is still simple physical method, and due to the restriction of cost, purification efficiency is not high, so tar in gas content is still higher.This accelerates the loss of equipment on the one hand, adds the servicing time of equipment on the other hand, reduces the utilization ratio of equipment, the total cost of gasifying electricity generation is increased.
Three, coke tar cracking and process.Under current state of the art, coke tar cracking is not satisfactorily resolved, and this is also a most important technical barrier of current Biomass Gasification & Power Generation.
Four, wastewater treatment.Containing a lot of ash and tar in the combustion gas that gasifying biomass produces, combustion gas first must carry out purifying treatment.Current gas sweetening is the greatest weakness of domestic biomass gasification technology application, needs more to study.Often adopt method for washing to gasification purification at present, method for washing not only reduces system efficiency, and produces a great deal of containing tar and waste water.These waste water contain the objectionable impurities such as ash and tar, need to carry out harmless treatment before discharge, and recycle as far as possible.But wastewater treatment at present still lacks economically viable effective way, and in order to reduce costs, sometimes directly discharge, in waste water, objectionable impurities substantially exceeds the requirement of environmental protection, brings secondary pollution.
Five, biomass power generation suffers great loss.All the time, whether mode of biomass energy utilization should never be interrupted in the arguement based on direct combustion power generation.China's approved has built up tens biomass power generation projects, and gross generation is more than 400,000 kilowatt/year.But current practical situation are, the biomass power generation project whole industry is lost, and minority biomass power plant " benefit " is good, also for no other reason than that could maintain normal operation by state subsidies.
Six, Biomass Gasification Power Generation Technology must solve gas-purification and gas storage two large problems by emphasis.Domesticly at present in Biomass Gasification Power Generation Technology, adopt combustion gas water washing cleaning method and electric tar oil process, the method of these two kinds of gas-purifications is all infeasible, adopt the practice of gas-holder storage combustion gas also inadvisable economically, new technology must thoroughly be improved in these areas.
