Problems solved by technology

However, the yield and grade of charcoal in this technology are reduced, and quality control is more difficult to operate; the CO content in the gas product is greatly increased and exceeds the standard, and the effective components of the liquid product are reduced; as a result, users will choose to directly discharge the gas-liquid product into the air. , the potential environmental risk is very large

Abstract

The invention discloses a novel vertical tube moving bed continuous pyrolysis apparatus for biomass. The apparatus mainly comprises a combustion heating furnace, a pyrolysis heat supply flue, a vertical tube pyrolysis moving bed, a coke air-cooling pipe, a rotary feed valve, a rotary discharge valve, a discharging packing auger, etc. According to the invention, high temperature flue gas is used to scour rows of pyrolysis vertical tubes in the moving bed to reinforce the effect of heat transfer from an external heat source to pyrolysis equipment, and biomass raw materials successively undergo thermal decomposition in the pyrolysis tubes with a great length-diameter ratio; heat released in cooling of coke is utilized for preheating of heating air, which enables energy to be fully utilized; and through adjustment by the rotary feed valve and the rotary discharge valve and gravity of materials, continuous production in the process of pyrolysis is realized.

Description

technical field [0001] The invention relates to a biomass pyrolysis device, which is a continuous pyrolysis device for indirect heating of biomass. The biomass undergoes dehydration, devolatilization, polycondensation into charcoal, cooling and other processes in the device to become high-quality biomass. Substance coke. Background technique [0002] Pyrolysis is a high-efficiency conversion method, which can quickly convert biomass into three valuable products: charcoal, gas and oil. At present, the research and development and application of biomass pyrolysis focus more on the utilization of a single product, while not paying enough attention to other products. Not only is the economy difficult to guarantee, but there are also hidden dangers of secondary pollution. The development of pyrolysis-based carbon, gas, and oil polygeneration technology to produce a variety of high value-added products can effectively maximize the economic and environmental benefits of the entire...
