Carbonization furnace

The carbonization furnace provided by the invention comprises a belt type feeding mechanism, a dry distillation furnace, a gas collection mechanism, a venturi tower, a rotational flow plate tower, a fan, a filter dust remover and a cooling system, the dry distillation furnace, the rotational flow plate tower and the venturi tower are arranged in parallel in the vertical direction, and the belt type feeding mechanism is arranged to automatically convey coal into the dry distillation furnace; a carbonization chamber in the dry distillation furnace is used for treating coal, the treated coal gas sequentially passes through a gas collection mechanism, a venturi tower and a rotational flow plate tower and is sucked into a filter dust remover by a fan, and then part of the treated coal gas enters the dry distillation furnace again for use; wherein a material distribution device is arranged in the carbonization chamber and comprises multiple stages of material distribution layers, and the layers of the multiple stag
