The feeding port advanced charring and plugging problems can be solved, the process requirements of fast biomass pyrolysis can be met, the pyrolysis equipment producing and maintaining time can be shortened, the pyrolysis oil producing efficiency is improved, the maintaining cost is reduced effectively, and the technology guaranteeing effect can be achieved for large-scale pyrolysis production development.

Description

technical field [0001] The invention relates to a spiral-pulse pneumatic mixing feeder for mobile biomass pyrolysis, belonging to the technical field of biomass pyrolysis. Background technique [0002] Biomass energy occupies an important position in the new energy that is constantly being valued. Fast pyrolysis technology is getting more and more attention in China, and it is one of the important technologies for converting biomass energy. [0003] At present, fluidized bed pyrolysis technology, as one of the most promising pyrolysis technologies, is widely used in the production of pyrolysis oil and biomass charcoal particles. In the process of fluidized bed pyrolysis, it is necessary to reasonably use conveying equipment to transport biomass raw material particles (also known as powder) into the fluidized bed reactor. In order to enable fast pyrolysis or flash pyrolysis of the powder, the fluidized zone in the reactor usually needs to be heated to about 400-550°C, so tha...
