The utility model discloses a novel outlet structure for an extraction tower, which includes a lower seal head (1) of the extraction tower, and a connecting pipe (2) connected onto the lower seal head (1), wherein a reducing pipe (3) provided with a big upper opened end and a small lower opened end are flexibly connected with the lower end of the connecting pipe (2); the big upper opening of the reducing pipe (3) is connected with the lower end of the connecting pipe (2); the small lower opening of the reducing pipe (3) is flexibly connected with a vertical connecting pipe (5) of a horizontal outlet pipe (4). According to the utility model, the outlet cross section at the lower seal head of the tower body is appropriately enlarged, the detachable reducing section in flanged connection is used for adjustment, and a flange cover is arranged at the end part of the horizontal pipeline, so that the problems that scaling at the lower outlet of the tower body is difficult to clean, a liner is difficult to fix and easy to fall off and is complicated to replace, are solved, time for shut-down overhaul of a production device is shortened and frequency of shut-down overhaul of the production device is reduced, and the economic benefit is remarkable.
