Description
Technical field
The utility model relates to fresh biomass process field, particularly relates to the high-valued treatment unit of fresh biomass based on microwave hydrothermal carbonization, is applicable to the fresh biomass such as agriculture and forestry organic waste material, animal waste and waterplant.
Background technology
China is a developing country, Ye Shiyige large agricultural country, biomass resource reserves very abundant.But a lot of biomass resource is considered as being a kind of rubbish, although some is utilized, also just simple burning, utilization ratio very low.Until the utilization of biomass is just by attention gradually in recent years, it has many utility values: first, and biomass itself are low-sulfur, low nitrogen, low-ash a kind of material; Secondly, inside numerous renewable energy sources, biomass can be converted into liquid fuel.Inside the energy consumption in the world, biomass energy just account for 15% ~ 18%, as compared to Sweet natural gas, coal and oil the 4th, residence, as can be seen here, in energy source raw material, and the potentiality of biomass energy very large.The more important thing is, as a kind of energy, biomass can realize the zero release of carbon, the carbonic acid gas that biomass emit when utilizing, and are of equal value with absorbing the carbonic acid gas come in biological growth and development process from nature.This just effectively can solve the problem of environmental pollution that combustion of fossil fuels is brought.The kind that biomass comprise is very many, such as the resource such as forestry, agricultural, the ight soil of poultry, also has the rubbish in city, industry and business and some organic wastes.And in China, 6.56 hundred million tons of standard coals can be about as much as every year for the biomass energy of exploitation, how making good use of this part resource is a problem demanding prompt solution, and this not only can solve the energy shortage problem of China, also effectively can solve the problem of environmental pollution of China.In order to make the pollution-free energy transforming into us and need of biomass clean, the technology such as burning, pyrolysis, fermentation and hydrolysis are successively developed use.In recent years, hydrothermal technique had attracted the sight of numerous studies person with its exclusive feature, became the focus that researchist pays close attention to.The definition of hydrothermal technique very simple, first temperature and pressure is certain, then the participation of biomass and water will be had in reaction process, the product finally obtained comprises gas, liquid and solid, operating parameters is different, the productivity ratio of product also can not be identical, and biomass water thermally liquefy, biomass water are thermal evaporation, biomass by hydro-thermal carbonization these three kinds is also come therefrom to biomass by hydro-thermal technology classification.
The biomass resource that China can develop has agricultural wastes, forestry waste, feces of livestock and poultry, domestic sewage sludge, waterplant and energy-source plant.Fresh biomass generally has higher water content, wood fiber biomass water ratio is about 8 ~ 23% (wet basis), hydrobiont matter, as larger in water content such as Herba Eichhorniae, duckweed, Enteromorphas, wherein Herba Eichhorniae water content is up to about 95%, and the water content of feces of livestock and poultry is about 60%-90%.Therefore, the problems such as higher water content, the thermal value of unit mass are low, the complexity of great number running cost and treatment process constrain the recycling of the higher biomass of water ratio, are how very necessary for the processing and utilizing technology that the exploitation of water ratio higher biomass is suitable.Therefore, biomass by hydro-thermal carbonization is extensively launched as a kind of novel biomass carbonization technology, in whole process this parameter of water capacity without any restriction, be completely unwanted for the operation such as drying treatment.Biomass are mixed according to a certain percentage completely with water and puts into reactor, in certain temperature (180-250 DEG C), reaction times (4-24 hour), and the hydro-thermal reaction that under pressure, (14-276bar) carries out, mainly obtain solid product hydro-thermal charcoal.Under this condition, required temperature and pressure is all lower, and condition is relatively gentle.From energy density, hydro-thermal charcoal quality, close to peat and lignite, can be used as composite solid fuel and directly uses, and compared with pyrolysis coke, finds that hydro-thermal charcoal has higher energy density; In pyrolysis coke, remain the almost metal-salt caused by ash content of 100%, and in hydro-thermal charcoal, ash oontent is only its 40% compared with former state, in addition, hydro-thermal charcoal also has the feature such as higher thermo-efficiency and the discharge of low stain thing.In addition, by raw material after certain hydro-thermal cross-linking carbonization process, size uniformity, the good charcoal of pattern can be obtained, the carbon functional materials of nanoscale can be had by synthesis upgrading as efficient stable, and be widely used in the field such as electrode materials, fuel cell.
But higher biomass by hydrolyzation speed will be kept at lower hydrothermal carbonization temperature to ensure the abundant conversion of biomass, realization for fresh biomass hydrothermal carbonization synthesis c-based nanomaterial technique is very important, is a feasible way by introducing microwave field in hydrothermal carbonization process.Usually, the rotational frequency of the various polar molecules such as the water in liquid product, carbohydrate, aldehydes, phenols is in microwave range, the microwave of some strength can be absorbed, and under microwave action, make kinetic energy-microwave energy be heat energy, and fast, reacting by heating thing equably, reach the object improving chemical reaction rate.Microwave also has non-thermal effect except having heat effect, can promote grain growing, accelerates chemical reaction, shortens the hydrothermal carbonization reaction times.It is more weak that biomass itself absorb microwave ability, but have very strong absorption microwave ability along with its intermediate product produced of carrying out of thermal hydrolysis reaction, makes biomass also can use the feature of microwave fast heating, reach fast decoupled object.Microwave is incorporated into the hydrothermal carbonization technique based on High water cut biomass, this plays an important role for the Efficient Conversion and product higher value application realizing High water cut biomass.
