Problems solved by technology

Another example is the fixed bed pyrolysis reactor, which is more suitable for the pyrolysis gasification and pyrolysis carbonization of biomass, but not suitable for the pyrolysis liquefaction of biomass, and because the biomass material in the fixed bed is relatively stable And thermal conductivity is not good, it will inevitably cause problems such as uneven bed pyrolysis, which limits the pyrolysis capacity of the fixed bed pyrolysis reactor under the condition of isolated air

Abstract

The invention relates to a spiral biomass pyrolysis reactor with drying function. The discharge hole of a spiral feeder of the reactor is communicated with one side of the lower part of a vertical drying and lifting tube; the bottom of the drying and lifting tube is communicated with the air outlet of a draft fan, the top is communicated with the charge hole of a spiral pyrolysis reactor through a cyclone separator; the other end of the spiral pyrolysis reactor is provided with a pyrolytic carbon outlet and a pyrolysis gas outlet; and the input end of the spiral pyrolysis reactor is connected with a speed regulating motor, the middle of the spiral pyrolysis reactor is in a burning and heating chamber, and the middle of the top of the burning and heating chamber is provided with a smoke outlet and communicated with the air inlet of the draft fan. The heating temperature of the outer wall of the spiral pyrolysis reactor and the screw speed are adjusted to change the pyrolysis reaction temperature and pyrolysis reaction time, thus pyrolysis gasification, pyrolysis liquefaction or / and pyrolysis carbonization of biomass can be realized; and the high temperature smoke generated in the process of heating the pyrolysis reactor can be utilized to dry the bionass material.

Description

technical field [0001] The invention belongs to the technical field of biomass pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization, and specifically relates to a reaction device for biomass pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization. Background technique [0002] Biomass can be pyrolyzed to obtain gas, liquid and solid three products under the condition of isolation of air or limited supply of air, and the yield of the three products is related to the heating temperature and heating rate: high temperature (700~900°C or higher) The pyrolysis product under high temperature conditions is mainly gas, so it is called pyrolysis gasification (also known as retort gasification); the pyrolysis product under medium temperature (450~550°C) and rapid heating conditions is mainly liquid, so it is called pyrolysis liquefaction; The pyrolysis product under medium temperature (400~500°C) and slow heating conditions is mainly solid, so i...
