Description

A kind of processing method reducing biomass granule fuel sulfur content
Technical field
The invention mainly relates to biomass granule fuel processing technique fields more particularly to a kind of reduction biological particles to fire Expect the processing method of sulfur content.
Background technique
China is a large agricultural country, and sawdust, bamboo scraps, branch, stalk, plant shell etc. is all the waste that agricultural generates, Overwhelming majority area is all to be merely able to sub-fraction nutritional ingredient and entered soil, released these waste combustion (of oil) insitus at present The carbon dioxide of releasing but produces very big harm to environment;Biomass granule fuel is with sawdust, bamboo scraps, branch, straw Stalk, plant shell etc. are raw material, by professed machine, special process, without any chemical addition agent, of high pressure low temperature compression forming Agriculture waste material can be sufficiently used as burning by granular fuel.
But the preparation of biomass granule fuel is also immature at present, still release is a large amount of during burning for fuel Sulfur-bearing volatile ingredient, China's biomass granule fuel lacks detection method at present, typically according to the life of Sweden and European Union Material grains classification standard indicates its sulfur content less than 0.07%, but one disclosed in existing 108239562 A of patent document CN Kind biomass compound fuel, specifically disclosing preparation of fuel into outer dimension is 3.5*2.5*1.58cm ellipse, which can It is suitble to the use fuel standard Lower heat value of various fixed grates and chain grate boiler>5000 kilocalories, sulphur<0.3%, fugitive constituent 35%, ash content<10%, fixed carbon>50%, it is clear that the sulfur content in patent document is higher and uncertain, and therefore, it is necessary to one kind to subtract The processing method of few biomass granule fuel sulfur content.
Summary of the invention
In order to make up the defect of prior art, the object of the present invention is to provide a kind of reduction biomass granule fuel sulfur contents Processing method.
A kind of processing method reducing biomass granule fuel sulfur content, includes the following steps:
(1)It crushes:Biomass material is crushed to 120 ~ 140 mesh, obtains crushed material;
(2)Fermentation:Added water to submerge into crushed material, access zymophyte, in 24 ~ 26 DEG C ferment at constant temperature 6 ~ 7 days, take floating material, obtain Fermentation material and fermentation liquid;
(3)Washing:The acetum that volume fraction is 1 ~ 2% is added into fermentation material, in 50 ~ 55 DEG C, 31 ~ 33kHz supersound washing It 25 ~ 30 minutes, washes repeatedly 2 ~ 3 times, filtering obtains washing material and cleaning solution;
(4)Water process:Fermentation liquid and cleaning solution are uniformly mixed, adjust pH to 6 ~ 7, freeze concentration to volume is original 1/4 ~ 1/5, obtain concentrate;
(5)It is granulated:Washing material is dried, is granulated, obtains low sulfur content biomass granule fuel.
The step(2)Zymophyte, through re-activation, additional amount is the 4 ~ 6% of biomass material weight, by following heavy Measure the bacterial strain composition of part:Sulfur bacteria 17 ~ 19, iron bacteria 10 ~ 12, Bifidobacterium 5 ~ 7.
The step(4)Adjusting pH, the acetum or mass percentage concentration for being 3 ~ 4% with volume fraction be 0.5 ~ 0.7% sodium hydroxide solution.
The concentrate that the method for reducing biomass granule fuel fluxing power obtains, can be used as liquid fertilizer and feed adds Add agent.
The low sulfur content biomass granule fuel that the processing method for reducing biomass granule fuel sulfur content obtains.
It is an advantage of the invention that:The processing method provided by the invention for reducing biomass granule fuel sulfur content, method letter Single, the sulfur content of obtained biomass granule fuel is down to 0.004% hereinafter, burning is abundant, hence it is evident that reduces biological particles combustion Sulfur content in material, it is environmentally protective;Biomass material is added zymophyte and ferment when low temperature is long after crushing, zymophyte is thin by sulphur Bacterium, iron bacteria and Bifidobacterium composition, sulfur bacteria can sufficiently decompose and using the sulphur in biomass material, make extra sulphur with The iron that iron bacteria generates forms ferrous sulfate and is deposited in fermentation liquid, and the biomass material of floating is taken out after fermentation, contains sulphur Amount is substantially reduced;Fermentation material is placed in progress high temperature ultrasonic washing in acetum after fermentation, removal biomass material surface is residual The sulfur-bearing ingredient stayed reduces the sulfur-bearing volatile matter generated when fuel combustion, conducive to the protection of environment;It is produced in fermentation and washing process The feed addictive that can be used as vegetable fertilizer or animal after raw liquid collection concentration, can turn waste into wealth, improve added value, The no pollution discharge for realizing treatment process, is conducive to environmental protection;Raw material is dried and is granulated after washing, conducive to filling for fuel Divided combustion saves mass energy.
