Description
Art
The invention belongs to agricultural mechanical field, be applicable to the charing of " biomass ", particularly the moveable straw charring of one goes back field charring furnace and carbonizing method thereof nearby.
Background technology
Term " biomass " comprises woody and herbal timber, wood chip, stalk, corn cob, nutshell, bagasse, bacterium mushroom cultivate native the like waste, also can comprise mud etc. the carbonaceous material of city organic solid waste, sewage work.Term " charcoal (biochar) " refers to " biomass " for raw material, under anoxic conditions through the solid product of high temperature pyrolysis (temperature is lower than 600 DEG C), also can be described as biological black wood charcoal.
According to not exclusively estimating that the whole world is produced stalk nearly 20 per year and recalled ton, 2003, China's stalk resource output reaches 7.9 hundred million tons, and annual with the speed steady-state growth of 0.12 hundred million ton.China rural area mainly contains rice straw, wheat stalk, maize straw, and wherein maize straw accounts for 36.7%, and rice straw accounts for 27.5%, and wheat stalk accounts for 15.2%.
The recycling of stalk, had both related to rural area huge numbers of families, also related to soil fertility in agroecosystem, soil conservation, environment and food safety and sustainable development, had caused various countries' common concern in recent years.In history, there is the fine tradition utilizing stalk in China, and agriculture domestic stalk builds a house and covers a day rain cover, makes a fire and cooks, with stalk stock keeping collected manure also field.But, along with traditional agriculture is to the transformation of agricultural modernization, and the development of economic society, rural energy, feed structure change, and rural laborer's cost raises up, and traditional straw utilization approach there occurs historic shift.Say, on-site incineration is most economical, method of disposal easily.Investigation statistics shows, under current fossil energy price and agricultural workforce's cost conditions, for the family of income level higher than 10,000 yuan, the behavior of crop straw burning is more general.But following environmental pollution and the wasting of resources have caused the concern of the whole society.
Straw-returning is one of better outlet solving stalk surplus, but also cost too high, service undersupply in field is one of straw-returning reason of not carrying out in a large number.In addition, also field stalk is under microbial process, equally also can
Produce a large amount of greenhouse gases CO
2discharge.
Straw power generation is one of stalk outlet be expected most, and the straw power generation of China is at the early-stage, still there is many problems at present.As purchase, transportation cost is high, storage place is large.Equally also can produce a large amount of greenhouse gases CO
2discharge.
For many years, using in a large number of chemical fertilizer and agricultural chemicals, makes soil compaction continuous quality decline, and heavy metal contamination has become the key of restriction agricultural sustainable development.
Document [1] Wang Meng sprouts Zhou Qixing, the soil environment effect of charcoal and Mechanism Study thereof, [J] environmental chemistry 2013,32 (5); 768-780
Document [2] Zhang Wenling, Li Guihua, Gao Weidong etc., impact [J] the Chinese agronomy of biomass charcoal on soil property and crop yield circulates a notice of 2009,25 (17); 153-157,
Summarize the achievement in research of the soil environment effect aspect of charcoal in recent years, research proves: charcoal has loose porous and huge surface-area and cation exchange capacity, soil physico-chemical property can be improved, moisturizing and the ventilation property of soil can be improved, make crop yield, and the pollutent that can adsorb in soil, reduce its biological effectiveness and Transport And Transformation ability; The bio-toxicity that the alkalescence of charcoal reduces pollutant in soil for improvement acid soil has very large potential; Charcoal can also provide the place of growth and breeding for microorganism, is conducive to the degraded to pollutent, but can protect again by the degraded from microorganism of the organism that adsorbs simultaneously, different on different microorganisms impact; Charcoal is also useful to soil useful animals such as earthworms.In addition, charcoal also can make chemical fertilizer have slow releasing function, improves fertilising efficiency.
Particularly over nearly 8 years, reply climate change and the reduction of greenhouse gas discharge that proposes is appointed how day by day arduous, charcoal may be the effective way addressed this problem.The latest study proves; Charcoal can increase carbon base in soil and reduce the discharge of greenhouse gases.
The carbon remittance effect in charcoal also field is expected to include CDM carbon transaction in, by charcoal also field 1hm
2compensate 5 dollars of meters, 100,000,000 hm
2compensation volume will reach more than 500,000,000 dollars, this for China's agricultural development and increasing peasant income favourable.Therefore, exploitation stalk processes nearby also field nearby, can receive opportunity in carbon fixation and emission reduction, increase soil fertility raising per unit area yield and increasing peasant income.
In view of this, in recent years, around biomass carbonated technology, multinomial patent is proposed both at home and abroad.
