Abstract

The invention discloses a pyrolysis device and method for a carbonaceous substance. The pyrolysis device for the carbonaceous substance comprises a furnace body, an upper heat radiation pipe, a lower heat radiation pipe, a solid partition plate and a porous partition plate, wherein a hearth is provided with a pyrolysis gas inlet and a pyrolysis gas outlet; the solid partition plate is arranged between the upper heat radiation pipe and the lower heat radiation pipe and is adjacent to the lower heat radiation pipe; the porous partition plate is arranged between the solid partition plate and the upper heat radiation pipe; the pyrolysis gas inlet is located between the solid partition plate and the porous partition plate, and the pyrolysis gas outlet is located between the upper heat radiation pipe and the porous partition plate. According to the pyrolysis device for the carbonaceous substance, disclosed by the invention, the hearth is internally provided with the solid partition plate and the porous partition plate which are good in heat transfer performance, so that the flowing speed of pyrolysis gas is increased, and the forced convective heat transfer of the pyrolysis gas in the hearth is realized, thus the heat transfer effect is enhanced, the secondary pyrolysis probability of the pyrolysis gas is reduced, and the tar yield is increased.

Description

technical field [0001] The invention relates to a carbon-containing material pyrolysis device and a carbon-containing material pyrolysis method. Background technique [0002] Coal pyrolysis is a key step in the clean and efficient conversion and utilization of coal. Most of the existing quasi-industrialized lump coal pyrolysis technologies fail to realize large-scale production due to the disadvantages of poor thermal conductivity of coal, poor gas permeability of the material layer, uneven heating, low yield of tar obtained by pyrolysis, and uneven quality of semi-coke. industrial applications. The heat required for the material pyrolysis process in the common vertical retort furnace is mainly introduced from the heating furnace wall, so the thermal efficiency is low; and the rapid pyrolysis of the fluidized bed has the disadvantages of high dust content and low tar quality. [0003] In the related method for preparing light fuel from medium and low temperature coal tar b...
