| 摘要 |
The present invention relates to a reactor for the continuous production of charcoal, having a substantially vertical structure, comprising, in sequence, a top charging zone (1), a drying zone (2), a carbonization zone (3), a cooling zone (4) and a discharge zone (5), wherein the charging zone (1) has a smaller cross section than the drying zone (2) and has an extension (1') into the drying zone (2), forming an annular space (A) around the extension (V), which space comprises, in the wall of the drying zone (2), an outlet to a gas extraction line (23) for the recirculation of these gases into the reactor. The object of the invention lies in reducing sawdust drag by the gases extracted from the preheating zone, without substantially altering the shape and the size of the reactor, which is achieved due to the fact that the charging zone (1) is arranged eccentrically relatively to the drying zone (2), and that the outlet to the gas extraction line (23) of the drying zone (2) is located substantially on the larger area section of the annular space (A). |
