DRY DISTILLATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To facilitate the maintenance of a sealing material by reducing the number of sealing parts for sealing off a heating medium and pyrolytic gas from outside air in a dry distillation apparatus.

SOLUTION: An inner cylinder 3 connected with a small-diameter supply pipe 4 and a discharge pipe 5 at one end and the other end in the longitudinal direction is housed in a fixed oblong outer cylinder 1 to form an outside heating channel 17 between it and the outer cylinder 1. The supply pipe 4 is protruded to one end wall part passing through a sealing material 22a, and a protruded part is supported freely rotatably. The discharge pipe 5 is protruded to a separation chamber 20 connected to the other end of the outer cylinder 1 passing through a sealing material 22c, and a protruded part is supported freely rotatably. Discharge openings 25 having a necessary size are arranged in the circumferential direction in the circumferential wall part of a part positioned in the separation chamber 20 of the discharge pipe 5 and opened.
