Description

technical field

[0001] The invention relates to the technical field of utilization and conversion of biomass energy, in particular to a dynamic-bed biomass pyrolysis equipment suitable for rice husk pyrolysis. Background technique

[0002] Biomass is a clean and renewable energy source. Biomass fast pyrolysis technology is an important way to utilize biomass. The so-called pyrolysis is to use heat energy to break the molecular bonds of large molecular weight organic matter and hydrocarbons. The process of converting it into a low molecular weight substance with a smaller number of carbon atoms. Biomass pyrolysis is a biomass thermal degradation process that produces liquid (bio-oil), gas (combustible gas), and solid (coke) under complete anoxic conditions.

[0003] Traditional biomass conversion technologies include biomass gasification, biomass pyrolysis, biomass fermentation, etc. Among them, the use of biomass pyrolysis technology can not only convert biomass into fuels ...

Examples

Embodiment Construction

[0041] Such as figure 1 , 2 . As shown in 3: the moving bed biomass pyrolysis equipment includes a pyrolysis furnace body I, a feeding device II arranged at one end of the pyrolysis furnace body I, and a supply device connected to one side of the pyrolysis furnace body I through an air inlet passage 17. The wind device III and the discharge device IV arranged on the other side of the pyrolysis furnace body I.

[0042] When working, the material is sent to the pyrolysis furnace body I by the feeding device II after initial drying, and pyrolysis gas and solid residue are generated. The residue is discharged from the discharge device IV, and the gas is discharged from the pyrolysis gas outlet 10 and enters the condensation device. After condensation, the remaining pyrolysis gas is returned to the air supply device III to continue to be utilized.

[0043] Such as figure 2 , 3 , 5 and 6: the pyrolysis furnace body I includes a ventilation chamber A, a pyrolysis chamber B, and...
