Description
Technical field
The present invention principally falls into environmentally friendly technical field of new energies, and in particular to produce life using the waste residue for preparing gallic acid
Biomass fuel and preparation method.
Background technology
The production of gallic acid draws powder etc. as raw material with forest products plant gall or tower, by alkali process hydrolysis, neutralization, thick knot
The technical processs such as crystalline substance, decolorizing and refining be obtained, it is a kind of broad-spectrum fine chemical product, be mainly used in organic synthesiss,
Medicine, dyestuff, feedstuff, food, light industry and electronics industry.Wherein, Galla Chinensiss are the traditional woods special product product of China, and Galla Chinensiss are fitted
The mountain area and hills of warm and moist are preferably grown on, in China main producing region Guizhou, Sichuan, Hubei, Hunan, Shaanxi, Yunnan are concentrated on
Deng six provinces, the Gallnut yield in these provinces accounts for more than the 90% of national total output.Tens thousand of tons are used every year in the whole nation, main to use
In production gallic acid, but gallic acid production hydrolysis and subtractive process can produce a large amount of waste residues (mainly containing wood fibre
And activated carbon), often producing 1 ton of gallic acid can produce 0.6 ton of waste residue, all not be reused at present, mostly go out of use, so
Both the wasting of resources had been caused, to cause to topple over occupied ground, and also environmental pollution.
Tower draws (Tara) also known as Caesalpinia spinosaKuntze, vegetable formal name：CaesalpiniaspinosaKuntze, is Caesalpiniaceae Spruce beetle
Perennial plant, mainly originates in the states such as South America northwestward Peru, and its sub- reality is that tower that bean can be processed into tower that glue, tower that evergreen chinquapin
Glue, its soybean pod is tower and draws powder after crushing.Tower draws powder to be actually the mixture of a kind of tannin and wood fibre, wherein effectively into
Part is tannin, and it is that effective ingredient (tannin) content is 50% that tower draws powder, and wood fibre contains 40%, and moisture content is containing 10%.China is annual
Need import tower to draw powder to produce gallic acid, can equally produce a large amount of waste residues (mainly containing wood fibre and activated carbon), often give birth to
Producing 1 ton of gallic acid can produce 0.8 ton of waste residue, all not be reused at present.
Recent years biomass fuel boiler substitutes coal-burning boiler, contributes to energy saving and improves environment, by National Environmental
Protection portion and China environmental protection industry association list best practical technology of environmental protection in China project in.Biomass fuel boiler needs biomass
Fuel, existing biomass fuel mostly is rice husk, Pericarppium arachidis hypogaeae, corn cob, shell of Camelliaoleifera Abel, cotton seed hullss and " three surplus things " and passes through processing
The bulk environmental protection new forms of energy of generation.
At present, do not occur to utilize and prepare gallic acid (with the gallic acid that Galla Chinensiss or tower drawing powder are prepared as raw material)
Produced waste residue occurs for the technology that raw material prepares biomass fuel.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of waste residue production biomass fuel for utilizing and preparing gallic acid
Method, methods described is to prepare the waste residue of gallic acid as raw material, and process is simple, processing cost is low, makes waste residue be reused,
Forest products resource is saved, environmental pollution is reduced, there is provided block biomass fuel environmental protection new forms of energy.
The present invention is achieved by the following technical solutions：
A kind of method for producing biomass fuel using the waste residue for preparing gallic acid, be with the waste residue for preparing gallic acid
Raw material, a series of process are carried out to waste residue, and acquisition caloric value is big, fuel purity is high and sanitation and hygiene biomass fuels.
Further, methods described is specially：To prepare the waste residue of gallic acid as raw material, the PH of waste residue is adjusted, and it is right
Adjusting the waste residue after PH carries out heat treated, then carries out filter pressing, drying, granulation to waste residue, prepares the biomass fuel
Material.
Further, the waste residue for preparing gallic acid includes wood fibre, activated carbon and water；Wood fibre in waste residue
Mass percent be 25～30%；The mass percent of waste active carbon is 30～40% in waste residue；The quality percentage of water in slag

Further, the method comprising the steps of：
(1) will be drawn in waste residue of the powder as raw material prepares gallic acid produced by with Galla Chinensiss or tower and add a certain amount of water,
Heat treated is carried out, and PH to 6～7 is adjusted using sodium hydroxide solution；PH is adjusted to into 6～7, can avoid finally preparing
Biomass fuel for acidity, corrode boiler plant.
(2) by the waste residue after step (1) process, processed using filter press so that slag-liquid separation；
(3) slag charge produced in step (2) is dried using vacuum drier；
(4) using wood substance grain granulator, the dried slag charge that step (3) is produced is suppressed, prepares institute
State biomass fuel.
Further, in step (1), when adding water toward waste residue, amount of water is controlled in 1.5～2L/Kg waste residues.
Further, in step (1), the mass fraction of sodium hydroxide solution is 20～50%.
Further, in step (1), the condition of heat treated is specially：Heating-up temperature is 85～95 DEG C, and temperature retention time is
10～30min.Heat treated is carried out under the heating condition, the acidic materials in waste residue can be made to be dissolved completely in water, made
When adding sodium hydroxide, reaction is complete.
Further, in step (3), vacuum drying condition is：Under the conditions of -0.08～-0.09Mpa, 3～5 are dried
Hour, and it is 20～30% to control moisture in dried slag charge；Moisture should be strictly controlled herein, according to granulation
Require, when moisture is too high, Jing pelletings machine biomass fuel moisture out is high, does not reach product requirement, moisture
It is too low, molding effect can be affected.
A kind of biomass fuel using the waste residue production for preparing gallic acid, according to the side of the production biomass fuel
Method is prepared, and the biomass fuel is columned granule, and the diameter of section of biomass fuel pellet is 6～8mm, granule
