Abstract
The invention discloses a low-cost bio-oil producing method. Biological materials (sawdust, tree bark, crop stems, fruit peels and the like) are directly put into a pyrolyzing furnace, e.g. an environment-friendly pyrolyzing furnace (with an application number of 200920062939.5), without dying. After the biological materials at the bottom of the furnace are lit up, a layer of sawdust or chaffs and the like is covered on the surface of the biological materials so as to isolate air. Under an anoxic condition, the biological materials slowly and automatically burn upwards and peripherad. When the temperature of the biological materials reaches 200-300 DEG C, the water contained in the biological materials is completely evaporated and the biological materials begin to undergo pyrolysis and charing. Then the pyrolyzed and charred biological materials are moved to a vertical pyrolyzing furnace for further high-temperature (higher than 400 DEG C) pyrolysis, and bio-oil, combustible gas and carbon are obtained from the decomposition.
Description
Technical field:
The present invention relates to a kind of low-cost bio-oil producing method.
Technical background:
Prior biological matter pyrolysis liquefaction technology is biomass waste material (wood sawdust, bark, crop stalk and pericarp etc.) oven dry, moves on to the pyrolysis oven pyrolysis again, decomposites bio oil, wood gas and charcoal.This method exists: the drying plant investment is big, and drying efficiency is low, and below 20%, drying time is long, the cost height, and the water content of the biomass of oven dry is still more than 5%, and the bio oil water content of producing is more than 20%.
Summary of the invention:
The object of the present invention is to provide a kind of facility investment few, the efficient height, with short production cycle, the bio oil water content is low, the production method that cost is low.
The object of the present invention is achieved like this, with biomass (wood sawdust, bark, crop stalk and pericarp etc.) not drying directly put into a pyrolysis oven, as a kind of environment-friendly type pyrolysis oven (application number is 200920062939.5), after lighting the biomass of furnace bottom, at biomass surface coverage one deck wood sawdust or husk etc., separate air again.Biomass under the anoxybiotic situation, upwards spontaneous combustion towards periphery at leisure, when biomass reach more than 200～300 ℃, the moisture evaporation in the biomass finishes, and the beginning pyrolysis charring.Then, the biomass of its pyrolysis charring are moved on in the vertical pyrolysis oven, further carry out high temperature (greater than 400 ℃) pyrolysis, decomposite bio oil, inflammable gas and charcoal.
This method has: the first, saved hotblast stove and baking room; The second, the biomass spontaneous combustion, rapid evaporation moisture content has reduced energy consumption; The 3rd, the bio oil water content is lower than 3%, has improved the quality of oil product.
Embodiment:
With biomass (wood sawdust, bark, crop stalk and pericarp etc.) not drying directly put into a pyrolysis oven, as a kind of environment-friendly type pyrolysis oven (application number is 200920062939.5), it is the rectangular parallelepiped of cutting with brick around, and area is several square metres to tens square metres, highly about 1 meter, the bottom surface is made up of brick, between brick and the brick space is arranged, with the brick supporting, form many bottom flues below the bottom surface, these flues merge into flue collector, and the outlet of flue collector links to each other with chimney.With the biomass in the stove in fine particle biomass such as surface coverage one deck wood sawdust or husks, separate air, light the biomass of furnace bottom, biomass are under the anoxybiotic situation, upwards spontaneous combustion towards periphery at leisure, in spontaneous combustion process, the moisture evaporation in the biomass, become the steam some and flow out along the brick of bottom and the space between the brick, a part is distributed from the surface of the wood sawdust that is covered with or husk etc.When biomass reach more than 200～300 ℃, the moisture evaporation in the biomass finishes and begins pyrolysis charring.Then, the biomass of its pyrolysis charring are moved on in the vertical pyrolysis oven, further carry out high temperature (greater than 400 ℃) pyrolysis, decomposite bio oil, inflammable gas and charcoal.
Claims (1)
1, a kind of low-cost bio-oil producing method, it is characterized in that: biomass are without oven dry, directly put into a pyrolysis oven low-temperature carbonization, light the biomass of furnace bottom, at biomass surface coverage one deck wood sawdust or husk etc.,, move on to again in the vertical pyrolysis oven again when biomass reach 200～300 ℃, carry out high temperature (greater than 400 ℃) pyrolysis, decomposite bio oil, wood gas and charcoal.
