Title:
ROTARY PYROLYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/023168
Kind Code:
A1
Abstract:
The present application discloses a rotary pyrolysis device, comprising a pyrolysis cylinder and a heating cylinder, the heating cylinder being sheathed on the outer periphery of the pyrolysis cylinder in a sealed manner, and the pyrolysis cylinder performing a rotation movement relative to the fixedly provided heating cylinder; further comprising a gas communication cavity provided inside the pyrolysis cylinder and isolated from the interior of the pyrolysis cylinder, the gas communication cavity being in communication with the heating cylinder for introducing the heated gas of the heating cylinder into the gas communication cavity, and a cavity wall of the gas communication cavity being used for transferring heat to the material inside the pyrolysis cylinder. Compared with heating the material in the pyrolysis cylinder only by the cylinder wall thereof in the prior art, the heated gas of the heating cylinder in the present application is introduced into the gas communication cavity, the heat transfer area inside the pyrolysis cylinder is greatly increased by means of the cavity wall of the gas communication cavity, allowing the material to perform contact heat transfer simultaneously with the cavity wall of the gas communication cavity and the inner cylinder wall of the pyrolysis cylinder, improving the heat transfer efficiency and the utilization rate of thermal energy, facilitating the progress of the pyrolysis reaction.
