Description
Technical field
The invention belongs to charcoal production equipment and process technical field, is related to a kind of life of rice straw charcoal
Product equipment and the technique for producing charcoal.
Background technology
As crop yield is improved year by year, Rural Urbanization Development and life of farmers level are lifted further,
Agricultural crop straw yield is dramatically increased, and at the same time, stalk progressively declines as the proportion of utilization of firewood, greatly
The superfluous stalk abandoned of amount is in the edge of a field, roadside or irrigation canals and ditches, or burns in the edge of a field, to ecological environment and life,
Property safety brings great hidden danger.China is main Rice Production country, produces substantial amounts of water every year
Rice straw, rice straw are the byproducts that paddy rice shelling obtains gained after seed, the stalk after shelling and attachment
Cured leaf becomes stalk, and most rice straw is arbitrarily abandoned and burned, and causes great environmental pollution,
The quality of life of impact peasant, also results in the significant wastage of resource.
Charcoal be bio-organic materials (living beings) in anoxic or anoxybiotic environment, after high temperature pyrolysis
The solid product of generation.The high-quality energy, soil conditioner is can not only be used for, also can be used as reducing agent, fertilizer
Slow-released carrier and carbon dioxide sequestration agent etc., are widely used to carbon fixation and emission reduction, water source purifying, heavy metal and inhale
Soil improvement etc. is echoed, can be that climate change, environmental pollution and soil function degeneration etc. is complete to a certain extent
Ball hot issue deeply concerned provides solution.Charcoal can also improve agricultural productivity, reduce intensive to carbon
The demand of fertilizer.The pore space structure of charcoal particle very easily assembles nutriment and beneficial microbe, so as to
Make soil become fertile, beneficial to plant growth, realize while volume increase, allowing agricultural have more continuation.Still better
It is that it is locked in carbon in biota, rather than allows it be discharged in the air.Biomass carbonated technology is generally acknowledged
Solve the problems, such as one of possible technique measure of climate change, with raw material sources extensively, low production cost,
Ecological safety, pollution-free, can the distinguishing feature such as spread.
It can be a kind of with carbon fixation and emission reduction with environmental area that the charcoal produced after biomass carbonated is applied to ecological
Effectively carbon remittance technology, is combined with agriculture, forestry, it is possible to resolve agriculture and forestry organic waste material pollution and greenhouse gas emission
Problem.Charcoal applies farmland, can be effectively improved soil physico-chemical property, increases crop yield, promotes agricultural
Sustainable development.Charcoal is a kind of economically viable mode of fixing carbon dioxide, not only have cured trees
With the carbon dioxide for having been absorbed in crop, its product " biological carbon " is stored in soil, thousand of years all without
Change, while production regenerative resource, soil fertility is also improved, improve crop yield.Raw
Thing charcoal can be embedded in discarded colliery, or in placing into the soil when cultivating.Charcoal landfill also helps improvement soil
Earth drainage system, and 80% or so such as nitric oxide and methane isothermal chamber gas are sealed up for safekeeping in soil, resistance
Stop which to be discharged in air.At present rice straw charcoal production equipment and for produce charcoal technique very
Many, but high energy consumption, long the production cycle, production process poor controllability, cause gained charcoal apparent specific gravity little.
Therefore work out a kind of energy consumption low, cycle is short, the big charcoal production equipment of gained charcoal apparent specific gravity and
For the technique of charcoal is produced, there is important economic benefit and social value in association area.
