Description
Technical field
The invention belongs to plant straw biological mass-energy source domain, and in particular to one kind is using maize straw charcoal as primary raw material system
Standby solid molding fuel and preparation method thereof.
Background technology
The energy and environmental problem turn into the focus of global concern, although coal, oil and natural gas these conventional energy resources are extremely
The present is still the main source of fuel, still, the oil, natural gas and the coal resources that are available for exploitation of the current proven reserve in the whole world
Exhaustion will be used up 25, after 27 and 97 years respectively.With the increasingly depleted of fossil energy and being on the rise for environmental problem, exploitation
Using clean renewable resources into urgent problem.In this context, biomass energy is as uniquely can storing and transport
Renewable green energy resource, efficiently conversion and clean utilization potentiality are increasingly subject to the attention of countries in the world for it.Country《Biomass energy
Develop " 12 " planning》Clearly propose to set up biomass molding fuel production, accumulating and use system, promote biological in city
Matter shaped fuel central heating, cleaning cooking and heating fuel popularization and application are used as in rural area.
The population for having about 39% in the world is carrying out cooking and heating using stalk fuel, but the overwhelming majority is by combustion (of oil) insitu
Or directly as fuel combustion, and rural area generally uses old-fashioned cooking stove, the thermal efficiency only has 10%.Also, the inorganization combustion of stalk
Burning is a big important sources of China's atmosphere pollution, and about 1.2 hundred million tons stalks are by unordered burning every year.Stalk it is direct without group
Utilization is knitted, both waste of resource, environment is polluted again, it is therefore desirable to which processing is used.To the utilization mainly solid biomass of stalk
It is compact formed, i.e., with the method for mechanical pressurization, original loose, unformed raw material is compressed into definite shape, certain close
The solid molding fuel of degree, it is possible to resolve the problem of storing is difficult, while making energy utilization more concentrate, burning is also more stablized.
At present, the research both at home and abroad to stalk forming technique is concentrated mainly on hot extrusion briquetting technique.But, although hot press forming technology
The combustion characteristics of biomass is improved, but calorific value is not significantly increased；In technological process, drying and hot-forming two link energy
Consumption is higher；Former critical component is easy to wear, and production cost is higher.Therefore, application is narrower, and can not be used as tradition
The substitute of fossil fuel and promoted on a large scale.
In order to make up these hot-forming deficiencies, charing moulding process has been developed.I.e. biomass is in no oxidant
(air, oxygen etc.) exists or is provided only with conditions of limit oxygen, by thermal chemical reaction that biomass macromolecular substances are (wooden
Quality, cellulose and hemicellulose) resolve into biological carbonaceous material compared with small molecule.Charcoal contains higher phosphorus content and heat
Value, relatively low ash content, volatile matter and sulfur content for global carbon, can also play the Significance for Environment of carbon sequestration, quilt
Titled with the title of " black gold ".It is biomass carbonated to have high energy transformation ratio, 95.5% is reached as high as, and by charing
Biomass molding charcoal made from moulding process, compared with direct curing molding, further reduces volume 20%, improves unit volume
Quality and calorific value, reduce fuel volatile matter content, combustibility is good.Due to raw fibre structure in carbonization process by
Destruction, macromolecule component is converted into charcoal by thermal cracking and discharges volatile matter (including fuel gas, pyrolkigneous liquid and tar etc.), because
And its extrusion process performance is improved, production equipment Meteorological is low, the mechanical wear and extrusion process process of profiled part
In power consumption substantially reduce.
Straw biomass is the loose structure of loose arrangement inside particle after carbonization process, and biomass is had by flexible
Machine composition granule becomes loose frangible inorganic carbon particle, so that its directly obtained shaped fuel density is small, anti-drop low intensity, and
And a large amount of lignin and hemicellulose in stalk are decomposed into DIC at high temperature after carbonization process, cause shaped fuel
Lack internal adhesive.All the time, the adhesive commonly used both at home and abroad has tar, lime, phenolic resin, lignin, corn to form sediment
Powder, tapioca starch etc..But, these traditional adhesives are usually respectively having shortcoming and deficiency using upper：It is prepared by tar class adhesive
Shaped fuel often tolerable temperature is relatively low, it is heated to be easily broken disintegrations, and the more flue gas of generation that burns, pollution environment；Stone
Grey adhesive can introduce higher content of ashes, while reducing the calorific value of shaped fuel；The generally cost such as phenolic resin is higher, meeting
Cause the increase of shaped fuel cost；The cohesiveness of the biology adhesive such as lignin, starch and poor, the prepared shaping of water proofing property
Charcoal is transported and shelf characteric is not good.Thus, shaped fuel prepared by traditional adhesive often because its processability, combustibility or
The deficiency of person's environmental performance, above has its limitation in application, it is impossible to real to turn into the substitute of conventional fossil fuel.
Fertilizer is irrigated in promise(China) Bioisystech Co., Ltd produces the accessory substance of enzyme preparation, is flour, starch etc.
Residue after the fermented reaction of raw material.First pass through lime and the step sterilization treatment of high temperature two, be then dehydrated product, processing and
Into.The fertile fertilizer of promise is containing Multiple components such as starch, carbohydrate, diatomite, N, P, K, Ca, Mg, Al, and Fourier transform-infrared spectrum shows
Show that a variety of functional groups such as hydroxyl, carbonyl, carboxyl are contained on the fertile fertile surface of promise, both can occur physical bond between charcoal particle,
Chemical bond can be formed again, so as to play cohesive action.The addition of the elements such as Mg, Ca, Al can also be effectively improved biomass fuel
Combustibility.Therefore, fertilizer is irrigated in promise the potentiality as good adhesive.
New Types of Environmental Materials tourmaline is a kind of natural silicate minerals of multielement, and main chemical compositions are SiO2、
TiO2、CaO、K2O、LiO、Al2O3、B2O3、MgO、Na2O、Fe2O3、FeO、MnO、P2O5.The formula of tourmaline is XYZSi6O18
(BO3)3W4(X is Na+、Ca2+、K+Or room；Y is Mg2+、Fe2+、Mn2+、Al3+、Fe3+、Mn3+、Cr3+、Ti4+、Li+；Z is Al3+、
Fe3+、Cr3+、Mg2+；W is OH-、F-、O2-), X, Y, the atom of Z location are different with ionic species to cause tourmaline composition and color
It is different.There is studies have shown that tourmaline to discharge anion, persistently occur DC static, released mineral matter and trace element.Cause
This, tourmaline can produce valence link power with the hydroxyl of biological carbon surface, carbonyl and carboxyl isopolarity group, while can improve into again
The combustibility of type charcoal.
