Description
Technical field
The present invention relates to biomass fuel technical field, particularly relate to a kind of oligosaprobic biomass molding fuel of zero-emission
And preparation method thereof.
Background technology
Biomass energy because it is renewable, aboundresources, environmental friendliness and become world's fourth largest energy, be also the most permissible
Transport and the clean reproducible energy stored, mainly by the biomass energy technology modernized by agricultural wastes, felling
Residue, feces of livestock and poultry, MSW, sanitary sewage become biological particles to fire with Raw material processings such as industrial organic waste waters
The end products such as material, biodiesel, bio-fuel ethanol.Biomass fuel is discharged almost without SO2 during later-stage utilization,
Decrease the acid rain caused by flue gas and the harm of greenhouse effect produced during it utilizes so that biomass energy has
The most wide application prospect and development space, thus Developing Biomass fuel has become the mankind and has solved energy problem and improve ring
One important means in border and developing direction.China is large agricultural country, and biomass resource enriches, the yield of annual agricultural crop straw
More than 700,000,000 t, wherein amount usable is about 5.055 hundred million t, accounts for the 50%-60% of Chinese biological matter total resources, therefore, converts it
Utilize significant.The raw materials such as agricultural crop straw exist loosely organized, density is little, distribution is not concentrated, the thermal efficiency is low, inconvenient
Many defects such as transport and storage, are unfavorable for utilizing on a large scale, utilize mechanical force that compressed biomass or extruding are become density relatively
Greatly, the thermal efficiency is high, it is simple to the solid fuel of transport storage is the most relatively advanced a kind of biomass economy mode.
It is tight to there is equipment attrition for straw compressing and forming in " molding fuel test is prepared in stalk anaerobic fermentation modification " literary composition
The antibiont degraded barrier that weight and anaerobic fermentation face, it is proposed that the thinking of shaped fuel is prepared in a kind of stalk anaerobic fermentation modification
And carried out experimental study.With corn straw as raw material in literary composition, the anaerobism that raw material carries out 10d and 20 d respectively by a definite date is sent out
Ferment, the biogas residue after fermentation size-reduced and dried in 100 DEG C, be compressed into the granular fuel of diameter 10 mm under the conditions of 6 MPa.
Result of the test shows: after stalk anaerobic fermentation, and the energy being retained in biogas residue is more than the energy transferred in biogas, straw biogas residue
Energy value high, but after fermentation 20 d, straw content of ashes is 3 times of non-fermented stalk, and its clinkering property may be made to increase
By force, the shaped fuel calorific value and prepared in literary composition only improves about 5.82% than raw material, it is impossible to meets blast furnace or has high heating value demand
Place, and exist when small-sized cooking stove misfire, the problem such as the length duration of ignition and smoke pollution, efficiency of combustion is low,
Need in addition modified to obtain high heating value, the novel biomass shaped fuel of resistive connection slag.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of oligosaprobic biomass moulding of zero-emission
Fuel and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of oligosaprobic biomass molding fuel of zero-emission, is prepared by the raw materials in: corn straw 100, Caulis Sacchari sinensis

Temperature 2-3 hour, is evaporated, and adds the dregs of fat ultrasonic grinding 10-15 minute, is dried and prepares combustion adjuvant;
(2) volcanic ash 5-10wt% hydrochloric acid solution is soaked 1-2 hour, with hot wash to without chloride ion, add water in 80-100
Ultrasonic Treatment 8-10 minute at DEG C, dries, and adds calcium oxide roasting 2-4 hour at 730-790 DEG C, is cooled to grinding at room temperature
Prepare modified volcanic ash;
(3) by corn straw with hot-water soak 10-12 hour of 60-70 DEG C, filter and put in fermentation vat, control fermentation vat temperature
At 30-50 DEG C, humidity is 50-60%, and anaerobic fermentation processes 20-30 hour, add modified volcanic ash, bagasse stir every
Air absolutely continues fermentation 10-20 days, filtering drying, puts into and is crushed to 60-80 mesh in pulverizer;
(4) in step (3) material, add combustion adjuvant, water and the mixing of other residual components, send into single lead screw ex truding briquetting machine, with 6MPa's
Briquetting pressure is squeezed into a diameter of 5-8mm, the cylindrical particle of a length of 3-8cm, is dried, discharging.
The invention have the advantage that the anaerobism that the present invention carries out 10-20d by a definite date with pretreated corn straw for raw material is sent out
After ferment, the relative amount of stalk hemicellulose and cellulose reduces, and lignin relative amount increases, and volatile matter content reduces, benzene alcohol
Extract declines can improve the mechanical endurance of shaped fuel, compound resistive connection slag agent and combustion-supporting after finally biogas residue drying being pulverized
