Description
Technical field
The present invention relates to field of new energy technologies, is specifically that one kind contains sepiolite composite biomass fuel and its preparation side
Method.
Background technology
Agriculture and forestry organic waste material is to produce substantial amounts of discarded object in farm-forestry crop harvest and process, for example, crop harvesting
When remain in the stalk in farmland, remaining rice husk, chaff skin in agricultural production process, the branch remained during production of forestry,
Leftover pieces of leaf, wood chip and timber processing etc., and the residue of food-processing industry discharge.China's agriculture and forestry organic waste material resource is rich
Richness, at present, agriculture and forestry organic waste material are loosely dispersed in wide area, except least a portion of agricultural crop straw be used for feed stripped,
Cook and warm oneself and be outer, it is most of by as discarded object abandon in field.The Land use systems of agriculture and forestry organic waste material have a lot, wherein agricultural
The direct burning of discarded object is to apply most Land use systems.However, for a long time because agriculture and forestry organic waste material directly burns the energy
Utilization ratio is low, and ignition temperature is low, limits its application.Various kilns heating in industrial production needs mass energy,
It is a huge utilization market, but to more than 1100 DEG C of the ignition temperature requirement of fuel, and use traditional combustion method
Temperature only has 600-700 DEG C, and the ignition temperature of the shaped fuel of agriculture and forestry organic waste material is also difficult to more than 1000 DEG C, it is impossible to adapts to industry
The requirement of fuel quality；It is high to the conventional gasification of agriculture and forestry organic waste material and liquefied fuel cost, it is impossible to adapt to industrial fuel economy and refer to
Target requirement.So 700,000,000 tons of stalks and 200,000,000 tons of forest trimmings caused by China is annual, it is impossible into Industrial Stoves fuel this
Just it is being adapted to the market of biomass dispersiveness feature.Most of stalks are afield incinerated, and are polluted and accident, dry branches and fallen leaves and
Weeds are even more to be allowed to rot.
Sepiolite is a kind of clay mineral of magnesium silicate containing Shuifu County for having layer chain structure.Orthorhombic system or monoclinic system,
Typically in block, earthy or fibrous agrregate.Color is white, light grey, dull gray, yellowish-brown, rose, bluish-green
Color.Fresh face is pearly luster, is earthy gloss after weathering.Hardness 2~3,2~2.5g/cm3 of density.Feel with cunning and puckery
Sense, glue tongue.Property is crisp under drying regime.Shrinkage factor is low, and plasticity is good, bigger than surface, and adsorptivity is strong.It is dissolved in hydrochloric acid, light.Hai Pao
Stone also has the performances such as decolouring, heat-insulated, insulation, anticorrosive, radioresistance and thermostabilization.It is main to originate in marine deposit-weathering transformation
In type mineral deposit；Also come across in hydrothermal solution mineral ore.
