Description
Technical field
The present invention relates to biomass resource utilization, stalks five to change the fields such as comprehensive utilization, biomass thermoelectricity and circular economy,
Specifically agricultural-forestry biomass classified use and low-carbon combined production device and its green technology.
Technical background
It is reported that the annual agricultural crop straw yield in China is up to 800,000,000 tons, and it is practical to only have a small number of parts to be utilized, wherein big absolutely
Majority is to be smashed to return field by machinery, causes serious soil pest and disease damage because that cannot degrade in time, so while government puts into effect
Severeer environmental improvement and prohibit burning policy, but burns phenomenon and happen occasionally.
Begin within 2008, domestic extensive starting agricultural crop straw five changes comprehensive utilization, thus National Development and Reform Committee and the Ministry of Agriculture
Joint publication " stalk comprehensive utilization technology (2014) " notice, clearly encourage and specification stalk ' Fertilizer Transformed, fodder, raw material,
Energy, base-material ' etc. five change comprehensive utilization techniques and industry.
Stalk essential characteristic: first is that Main Components cellulose 35~50%, hemicellulose 15~40%, lignin 15~
35%;Second is that classification is containing the more stalk of hemicellulose and the less stalk containing hemicellulose.
At the same time, the biomass thermoelectricity industry development in China is very fast at present, and manufacturing enterprise is up to thousand or more, agriculture therein
Woods abandoned biomass thermoelectricity project and number of the enterprise occupy significant proportion.
However, reality is the biomass thermal power technology compared with photovoltaic+energy storage generation of electricity by new energy has been approached the marketization
Simple and resource is devalued to be utilized seriously, and professional is caused still to rely on public subsidies existence.
In practice, in the biomass fuel that agricultural abandoned biomass thermoelectricity project and enterprise are stored up, existing crops are soft
Lightweight and all kinds of stalks of hard heavy, there are also discarded leaf, branch and tree roots, also there is discarded construction timber and production packaging wood
Material.
As it can be seen that agricultural abandoned biomass thermoelectricity project and enterprise, all simple by the biomass for all kinds of different specialities stored up
Singly extensive burning is not only unreasonable but also serious waste resource, so very necessary coproduction utilizes.
Said from economy and technical standpoint, biomass resource by it is extensive it is devalued as fuel use, be to cause current agricultural
The lower benefit of waste biomass thermoelectricity and the principal element for relying on public subsidies.
Conversely, if agriculture and forestry organic waste material thermoelectricity project and enterprise can size up the current situation and improve and extend pollution-free industry
The biomass resource stored up is carried out classification utilization and fine design, produces height by low-carbon energy advantage by chain
Agriculture and forestry organic waste material thermoelectricity comprehensive benefit had not only can be improved in value biomaterial, but also can save valuable biomass resource.
Containing the more stalk of hemicellulose, mainly there are the crops such as wheat, corn and jowar;Firstly, stalk hemicellulose is
Human society obtains the main path and biomass resource and agriculture of big healthy xylan and sweet taste product from nature so far
The high-valued important channel of crop material;Secondly, the lignocellulosic and its structure of stalk are the natural materials of green paper,
Therefore develop the papermaking of stalk cleaning pulping for protecting existing forest tree resource and earth vegetation particularly important.
Containing the less stalk of hemicellulose, mainly there are the crops such as beans and cotton;Hemicellulose contained by its stalk is few, this
It is the important measures for improving the enzymeization and fermentation production efficiency of current lignocellulosic ethyl alcohol.
Building and packing timber are more in the discarded forest of biomass resource, are mainly characterized by pollution greatly and rubbish is more, will
Its reproduction difficulty greatly and higher cost, so is burned generation thermoelectricity be relatively inexpensive and feasible production method.
In short, utilizing by biomass resource classification and low-carbon coproduction, the added value of biomass not only can be improved, but also can
Commodity are made in abundant biomass, especially contribute to explore Technology Ways and Nei Sheng that the subsidy of agricultural abandoned biomass thermoelectricity is exited
Mechanism.
It can be seen that developing agricultural abandoned biomass resource classification utilizes and extends low-carbon industry chain (supply chain), it is that solution is existing
The insufficient important directions of agricultural abandoned biomass thermoelectricity;For this purpose, the present invention remolds agricultural abandoned biomass element and industrial chain industry
State has innovated new model, new technology, new process and new equipment that agricultural-forestry biomass coupling stalk five changes comprehensive utilization, it is expected that into
One step pushes the fast development of green technology and industry.
