Description
Technical field
The present invention relates to the preparation field of biomass carbon, in particular to a kind of packaged type field original position oxygen consumption system
The apparatus and method for of standby biomass carbon.
Background technology
Excessively bring such as Soil degradation, soil pollution, agricultural product by chemical fertilizer and pesticide raising grain yield and be harmful to
Object is exceeded to wait environment and food safety hazards, is science and technology in the urgent need to address in Ecological Civilization Construction and problem of industry.
In recent years, the biomass carbon of " black gold " is described as by, becomes the useful material of nursing soil health already.It
It is the poroid solid matter generated under anoxic conditions through Pintsch process by biomass, has larger specific surface area, more contains
Oxygen activity group and some plant nutrients.It not only has improvement soil property, promotes soil fertility, mitigates soil pollution
It waits agronomy and ecological functions and increases soil carbon sink, reduces N2O and CH4One of technology option of isothermal chamber gas discharge.
《National Agricultural Sustainable Development Planning (2015-2030)》" charcoal improvement soil " clearly write-in is helped for the first time
Hold policy scope, with straw-returning, subsoiling of deep ploughing, manufacture application of organic fertilizers and green manuring same column.It can be seen that straw charring returning to the field
Possesses market, it is to practice the embodiment of straw charring returning to the field theory to build charcoal industry.
At present, charcoal industry still locates breeding phase in China, and production, transportation cost are very high, it is difficult in agricultural production
It promotes the use of.If crop material directly can be converted into biomass carbon in field, material transportation, storage can be saved, charcoal processing is set
Standby and place, the cost of multiple links such as the storage of charcoal finished product and transport.It is not only that straw-returning provides new thinking, also
Practicable condition can be provided for the agricultural application of biomass carbon.
In view of this, it is special to propose the present invention.
The content of the invention
The first object of the present invention is to provide a kind of packaged type field original position equipment that oxygen consumption prepares biomass carbon, if
Standby to simplify, simple operation moves the field mass production, it can be achieved that biomass carbon, of low cost, application easy to spread.
The second object of the present invention is to provide a kind of field original position method that oxygen consumption prepares biomass carbon, and this method can be straight
It is connected on field and oxygen consumption burning is carried out to biomass material, biomass carbon is made, it is cost-effective, and biomass carbon performance obtained is excellent
It is good.
In order to realize the above-mentioned purpose of the present invention, spy uses following technical scheme：
The equipment that a kind of packaged type field original position oxygen consumption prepares biomass carbon, puts down including charcoal processing groove body and packaged type
Platform；
The charcoal processing groove body for side wall it is porous and be dislocatedly distributed, bottom lock, open top, both ends be equipped with folding lead to
The hollow housing of air valve；
The charcoal processing groove body is mounted in top flat, on the wheel-mounted packaged type platform in bottom；
The packaged type table top is equipped with banding pressure adjustable type water drenching equipment.
In the prior art, biomass carbon is the process equipment preparation with batch production, and still, plant produced biomass carbon is set
It is standby complicated, it is unfavorable for promoting and applying.And from stalk recycling, storage, to making charcoal by using straws, finished product transport etc. links expense compared with
It is high.Therefore, the present inventor gropes by test of many times, and a kind of packaged type field original position oxygen consumption is made and prepares setting for biomass carbon
It is standby.In the equipment, charcoal processing core system includes charcoal processing groove body and water drenching equipment, and charcoal processing groove body is used to hold biomass to be processed
Raw material；Water drenching equipment is burned to a degree of biomass material offer water spray action for giving；Packaged type platform realizes system
Charcoal groove body moves, convenient for with shifting.
The equipment that a kind of packaged type field original position provided by the invention oxygen consumption prepares biomass carbon meets oxygen consumption and prepares life
The requirement of substance charcoal, equipment are simplified, simple operation, move the field mass production, it can be achieved that biomass carbon, at low cost
It is honest and clean, application easy to spread.
Wherein, charcoal processing groove body both ends are equipped with folding gas valve, can be switched according to demand, and that realizes oxygen supply can
Control property, to better conform to the demand of different situations.
