Abstract

The invention discloses a feeding device for continuous thermal cracking of biomass. The feeding device comprises an initial stock bin, a vibrating hopper, a spiral quantitative conveying mechanism, avibrating screen and a negative-pressure fine material feeding pipe, wherein the vibration hopper is fixedly mounted at the lower part of the initial stock bin; an inlet of the spiral quantitative material conveying mechanism is fixed to the lower portion of the vibration hopper, the vibration screen is arranged in the box body; the box body is communicated with an outlet of the spiral quantitative material conveying mechanism; a fine material outlet is formed in the bottom of the box body; and the negative pressure fine material feeding pipe is arranged at the fine material outlet. Materialscan be continuously and uniformly fed into the reactor in a granular state, so that the biomass feeding amount and the reaction quality in the reaction process of the fluidized bed can be effectivelycontrolled, and the yield of reaction products in the fluidized bed is increased.

Description

technical field [0001] The invention belongs to the field of biomass continuous thermal cracking equipment, in particular to a feed device for biomass continuous thermal cracking. Background technique [0002] my country is the world's largest energy consumer, and is currently facing dual pressures from economic growth and environmental protection. Biomass energy has outstanding characteristics such as large reserves, renewable, low pollution, and wide distribution. It plays an important role in coping with the imbalance between energy supply and demand, global warming, and protecting the ecological environment. It is considered to be an important factor for the sustainable development of human society. strategic energy. [0003] Fluidized bed biomass continuous pyrolysis technology can quickly and continuously convert low-value-added biomass into high-value-added bio-oil and other energy products, and is currently recognized as one of the most effective biomass energy util...
