Background technology
Constantly expand with industrial production, the technology constantly progressive, increasingly depleted of fossil energy resource and to the energy and ring
The enhancing of consciousness is protected, the mankind need find new, cleaning, sustainable alternative fuel.
Agriculture and forestry organic waste material is the main Types of reproducible biomass material, has huge dive to solving energy problem
Power.Agriculture and forestry organic waste material is that farm-forestry crop harvests and produces substantial amounts of discarded object in process, for example, being remained during crop harvesting
Remaining rice husk, chaff skin, the branch remained during production of forestry, leaf, wood in stalk in farmland, agricultural production process
Leftover pieces that bits and timber are processed etc., and the residue that food-processing industry is discharged.China produces about 1,400,000,000 tons of agricultural crop straw per year,
If rational exploitation and utilization, the fuel of about 700,000,000 tons of standard coals can be obtained, yule logs and forestry industrial wood waste annual production are roughly equal to 300,000,000
Ton standard coal, ought to turn into the emphasis of biomass utilization, but this part resource is fully utilized far away, and utilization rate is not enough
20%.
At present, agriculture and forestry organic waste material is loosely dispersed in wide area, except least a portion of agricultural crop straw is used for domestic animal
Feed, cook and warm oneself it is outer, it is most of by as discarded object abandon in field.The traditional treatment method of agriculture and forestry organic waste material is landfill
And burning, environmental pollution can be caused and cause disaster hidden-trouble；Other utilization ways newly developed, although energy utilization rate and economy
Benefit is all very high, but consumption is few, require high to agriculture and forestry organic waste material, it is impossible to fundamentally solve the processing of agriculture and forestry organic waste material resource
And Utilizing question.

It is even；
2) ferment, cellulase is added in 40~60 DEG C of 12~36h of enzymolysis by 10~200U/g mixed materials；Gained is digested
Liquid glucose is added by 2~3kg/ tons of ethanol carries out alcohol fermentation after dry ferments, fermentation temperature control is at 30~40 DEG C, and fermentation period is
48~96h；The ripe wine with dregs fermented directly band slag is distilled in destilling tower, and vapo(u)rizing temperature is maintained at 85~95 DEG C, tower top
The coarse ethanol of extraction delivers to rectifying column and carries out rectifying and dewatering rectifying in atmospheric conditions in 70~85 DEG C of progress, can obtain after rectifying
The alcohol product of purity 95%, fermentation residue is standby；
3) residue drying storage extruding clamp dog, carries out magnetic sorting, the metal cleared out of is sent to by the residue that step 2 is fermented
Regenerate unit and carry out regeneration, the residue of fermentation is further dried, it is ensured that moisture content is made within 15%, and with this product
The heat drying provided for fuel, natural air drying can be used in dry area, by above-mentioned well mixed and dried thing
Material, is dried to curable type cleaning generative fuel of different shapes, geomery can be by institute using single lead screw ex truding briquetting machine extruding as needed
The pore size of template of design reaches.
Beneficial effects of the present invention：The present invention produces new, high heating value biomass molding fuel skill using agriculture and forestry organic waste material
Art not only solves biomass molding fuel low heat value (general 3500-4000kcal/kg), high energy consumption, cost some row such as big
Biomass molding fuel industry problem, and bring great number profit return to enterprise.
