Description
Affiliated technical field
" a kind of fast, the method for large-scale production biofuel " relates to a kind of can realize fast and by the approach of destructive distillation carbonization biological material is converted into the concrete equipment of biomass through pyrolysis gas and two kinds of biofuels of biomass semicoke and makes the method for using.The technical field that belongs to ' resource and environment ' in ' support national economy sustainable development '.
Background technology
To be sun power be stored in the intravital form of energy of biomass with the form of chemical energy to biomass energy.It is carrier with biomass, derives from the photosynthesis of green plants directly or indirectly.
Biomass energy can directly act as a fuel and be converted into heat energy by burning in combustion equipment; Yet can not have oxygenant (air, oxygen, water vapour etc.) to exist or only provide under the condition of limited oxygen, be heated to certain temperature, method by thermal chemical reaction, biomass macromolecular substance (xylogen, Mierocrystalline cellulose and hemicellulose) is resolved into liquid biochemical fuel oil (BioOil), behind solid-state semicoke (Char) and non-condensing combustion gas the fuel materials such as (NCG) than small molecules, resemble the coal in the fossil oil, the oil and natural gas utilization of equally burning
(1) (2)
, therefore, reducing owing to aspect the greenhouse gases that fossil oil produces, have very big development potentiality because but the biofuel continuous utilization has environmental friendliness and reproducible double attribute.So how to develop, utilize biomass energy to substitute fossil oil, be subjected to the attention of each national government.
But we still still are converted into the form of heat energy for the form of a large amount of utilizations of biomass energy by burning in combustion equipment directly to act as a fuel at present.Be converted into the form of utilizing again behind gas, solid and the liquid fuel by thermochemical approach, also be in the early stage exploratory stage now, some are progressively promoting and are forming early stage market through the mature technology of practice test.
Biological material directly acted as a fuel in combustion equipment, obtain the form of energy by the incendiary mode, according to the difference of biomass form, mode, the biomass that can be divided into looses after combustion system that biomass directly loose to burn, the biomass compressed moulding burns break into bundle behind the bundle shape and burn mode, biomass and be crushed into powder combustion system behind the powder etc.But, biological material is in these direct incendiary processes, no matter the form of biomass is any forms, its combustion processes all has some following defectives, so that can not resemble the fossil oils such as coal and Sweet natural gas the favorable tissue burning and carry out industrial utilization
(3):
(1) the biomass moisture content is more, and burning needs higher drying temperature and long asks that the flue gas volume of generation is big, the heat loss due to exhaust gas height when dry;
(2) density of biomass fuel is little, and structure is more open, and under the combustion-supporting situation of air blast, front face area is big, is blown afloat easily, and the ratio of suspension combustion is big;
(3) thermal value of biomass is lower, and temperature of combustion is low, and temperature field in furnace is on the low side, is difficult to organize stable burning;
(4) biomass volatile content height, the temperature that burning is caught fire is on the low side again, and generally fugitive constituent is just separated out in a large number and is taken fire under 250 ℃～350 ℃ temperature, and this moment is as if amount of supplied air deficiency, the incomplete combustion loss that will increase fuel;
(5) to separate out the semicoke that the afterburnt produces (be coke to the biomass fugitive constituent.Be called " semicoke ", with expression and coal system coke different), be subjected to that ashes wrap up and the influence of air infiltration difficulty, the particle burning speed of semicoke is slow, after-flame is difficult.And the semicoke of the stalk biomass material production of plant had not both had intensity, and proportion is also little, and the flue gas of the burned generation of possibility is at any time taken away, and can not finish CO
2The reduction reaction of+C → 2CO.
In addition, because biomass contain more chlorine and alkaline matter (especially agricultural crop straw)
(2), easily on heating surface, forming the deposit corrosion problem during burning, the fly ash granule that contains mineral composition such as more basic metal is bonded in and forms deposition on the combustion equipment each several part heating surface, causes the contamination of heating surface, brings the etching problem of heating surface then.
Because above-listed many disadvantages makes biomass improve technical study by direct burning various biomass fuel processing technologies that obtain developing and the combustion equipment that is suitable for, and all has been subjected to certain influence.Wherein, be apparent that once vigorous several years ago " stalk direct combustion power generation factory " project of developing (major part has adopted " burning of bundle shape " mode) the most: these had once spent " stalk direct combustion power generation factory " that the over ten billion fund is built up, now but because multiple reason, major part has entered stop production to overhaul or suspending operations for consolidation state, has stopped operation.
Biological material is transformed into liquid biochemical fuel oil by thermochemical approach, use again behind in three kinds of biofuel products such as solid-state semicoke and non-condensing combustion gas one or more, then can not produce above-listed many disadvantages, because these several biofuels can resemble the coal in the fossil oil, oil and natural gas is the same, existing various with utilizing on the equipment.
But, according to both at home and abroad in the situation of carrying out aspect the exploitation of biomass thermal chemistry, owing to carry out problems such as the tooling cost of equipment maturity problem, switching process of thermochemistry conversion and environmental pollution, many sound very very tempting technology (as, the biomass-making oil tech), in fact still be in the early stage exploratory development phase now.Though some are actively promoting and are progressively forming early stage market through the mature technology of practice test; but; the biomass thermal chemical transformation technology and equipment that relies on the technology potentiality of technology self that project can be survived in market economy under the environmental protection requirement condition of strictness does not fully also occur till now.Most of project relies on the huge fiscal subsidy or the subsidy of government basically fully, can survive.
The content of invention
The purpose of " a kind of fast, the method for large-scale production biofuel " that the present invention proposes is exactly to wish the translating eqipment of the biomass energy with this technology potentiality can be provided; thereby realize that the large-scale biomass energy of using substitutes fossil energy, reduces the discharging of greenhouse gases.
What have this technology potentiality is a kind of new type of continuous destructive distillation carbonizing apparatus with following function:
1, used ased Load by the hot pyrolysis gas Zuo that biological material produced of destructive distillation, carbonization can working medium;
2, has the function of working medium being forced to carry out indirect heating;
3, have that to make heated working medium and carried out between the biomass of destructive distillation, carbonization with convective heat exchange be the function of large-area heat conduction of main simultaneous and radiation heat transfer;
4, have under the condition of secluding air, add starting material continuously and discharge the biomass through pyrolysis gas of generation and the function of two kinds of biofuels of biomass semicoke continuously.
Specifically; " a kind of quick; the method of large-scale production biofuel " technical characterictic be by including high-temperature gas working medium collection chamber 1 shown in (accompanying drawing 1); force to stir blower fan 2; blower fan flow deflector 3; heating chamber 4; hot pyrolysis gas circulation heating tube 5; burner 6; residual heat using device 7; hot pyrolysis gas outlet 8; down smoke-discharging exhanst gas outlet 9; starting material inlet 10; destructive distillation; the products export 11 of carbonization; destructive distillation; carbonization chamber 12; one of being formed has used by destructive distillation for shell and thermal insulation layer 13; the hot pyrolysis gas Zuo that material produced of carbonization is Load can working medium; force to be heated to certain temperature and be forced to stir blower fan 2 pressures carrying out body-internal-circulation also and from starting material inlet 10 under the secluding air state, to add destructive distillation at the hot pyrolysis gas circulation heating tube 5 that working medium is placed in the heating chamber 4; after the biological material of carbonization chamber 12 is finished heat exchange; in destructive distillation; it is best under the pressure of zero-pressure and the secluding air condition that carbonization chamber 12 maintains small positive negative pressure, and the continuous carbonization carbonizing apparatus of the biomass through pyrolysis gas of discharge conversion generation and two kinds of biofuels of biomass semicoke is finished continuously.
