Apparatus for rapid pyrolytic reaction

Abstract

The present invention provides an apparatus for rapid pyrolysis reaction, which comprises: a reactor, which comprises a reactor body defining a reaction space that forms a dispersion region, a pyrolysis region, and a discharge region from top to bottom; multilayer-regenerative radiant tubes, which are distributed at an interval in the height direction of the reactor body in the pyrolysis region, and each layer of regenerative radiant tubes consists of a plurality of regenerative radiant tubes distributed at an interval in the horizontal direction, a material distributor; a material inlet arranged in the dispersion region above the material distributor; a material distribution gas inlet, which is arranged in the dispersion region and communicates with the material distributor so as to utilize a material distribution gas to blow out the material in the material distributor into the dispersion region, so that the material falls into the pyrolysis region uniformly; a plurality of pyrolysis gas outlets, which are arranged in the dispersion region and/or the pyrolysis region respectively; and a semi-coke outlet arranged in the discharge region.
