Abstract

The utility model relates to the technical field of chemical separation, in particular to a liquid-liquid extraction tower for separating acetic acid from water, which comprises an extraction tower, an extraction agent feed port arranged at the bottom end of the extraction tower, a raw material feed port arranged at the top end of the extraction tower, an extraction phase discharge chute arranged at the top end of the extraction tower and an extraction phase discharge port arranged at the top end of the extraction tower. An upper U-shaped bent pipe is mounted on a discharge port of the extraction box, an extracted mixture forms an extraction phase at the top of the tower, and the extraction phase is collected through the extraction phase discharge groove and discharged through the extraction phase discharge port. And an upper U-shaped bent pipe is mounted on the extraction phase discharge port, so that the waste water is prevented from being carried to the extraction phase discharge port, the unextracted residual solution is prevented from being formed at the bottom of the tower, and the residual solution is collected through the raffinate phase discharge groove and then discharged through the raffinate phase discharge port. And a lower U-shaped bent pipe is arranged on the raffinate phase discharge hole, so that the extracting agent is prevented from overflowing from the tower kettle.
