AI Technical Summary
Technical Problem
The existing ethyl phenylacetate distillation device needs to stop working when replacing the carbon plate, resulting in discontinuous distillation work, inefficient and waste of energy.
Method used
A partition plate is arranged in the distillation tower to divide its inner cavity into two upper and lower cavity chambers. Activated carbon is provided in each cavity. The activated carbon in the upper and lower cavity chambers is decolorized by alternately using the activated carbon in the upper and lower cavity chambers to avoid shutdown and replacement.
Benefits of technology
It realizes that activated carbon replacement does not require shutdown, improves distillation efficiency, saves energy, and reduces emissions.

Abstract
The utility model discloses a rectification decoloring device based on ethyl phenylacetate, and relates to the technical field of rectification decoloring, and the rectification decoloring device based on ethyl phenylacetate comprises a rectification tower, and a blocking door plate is hinged to an opening in the front end of the rectification tower. Opening a valve above the second tee joint and a valve above the first tee joint, and closing a valve below the second tee joint and a valve below the first tee joint; steam generated by the evaporating tank passes through the activated carbon in the upper cavity of the rectifying tower; closing a valve above the second tee joint and a valve above the first tee joint, and opening a valve below the second tee joint and a valve below the first tee joint; the steam passes through the activated carbon in the lower cavity of the rectifying tower; the active carbon in the upper cavity and the lower cavity can be alternately used, so that the rectification work does not need to be stopped when the active carbon is replaced, and the rectification efficiency is improved.
