Moving bed biomass pyrolysis equipment

Abstract

The invention relates to a moving bed biomass pyrolysis equipment, which comprises a pyrolysis furnace body I, a feeding device II arranged at one end of the pyrolysis furnace body I, and a feed device II connected to one side of the pyrolysis furnace body I through an air inlet channel. The air supply device III and the discharge device IV arranged on the other side of the pyrolysis furnace body I, the pyrolysis furnace body I is provided with a transmission mechanism, characterized in that: the transmission mechanism includes The fixed push plate on I, the reciprocating cart, the movable push plate set on the reciprocating cart, the high-leg push plate and the foot push plate, the fixed push plate and the movable push plate are arranged alternately in sequence On the top of the reciprocating cart, the high-leg push-feeding plate and the bottom-foot push-feeder plate are successively overlapped and arranged on one end of the reciprocating cart. The present invention adopts a reciprocating push plate pyrolysis furnace, which not only can fully pyrolyze biomass materials, but also can separate gaseous products and solid particles in time, without causing fouling and blockage on the surface of the equipment, which not only improves the utilization rate of energy, Increased commercial value.

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 ...

AI Technical Summary

Problems solved by technology

However, since the biomass raw material is at normal temperature, the temperature of the fluidized bed is greatly reduced after entering the fluidized bed, so that it is difficult for the fluidized bed to reach the pyrolysis temperature of the biomass raw material, resulting in that the biomass raw material cannot be processed in the pyrolysis device. full pyrolysis

In addition, after the gaseous product condenses, it will scale with solid particles on the surface of the pipeline and equipment, causing blockage or making subsequent separation more difficult

And then affect the continuous operation of the process, which is not conducive to the industrialization of the technology, and also affects the process yield
