AI Technical Summary
Technical Problem
In existing technologies, the high gum content during the production of C9 resin affects product yield and price. Furthermore, distillation is insufficient to completely remove the gum from the OA solvent oil, leading to a decline in product quality.
Method used
Structured packing is installed at the discharge pipe of the distillation vessel, and the OA solvent oil in the receiving tank is backwashed through the flushing reflux pipe. The packing is fixed by a vacuum pump and a grate plate to reduce the gum content and return the gum to the distillation vessel.
Benefits of technology
It effectively reduces the gum content in OA solvent oil, improves product quality and yield, and requires minimal structural modification, making it highly valuable for widespread application.

Abstract
This utility model discloses a low-colloidal OA solvent oil production device, belonging to the field of C9 resin production. It includes a distillation kettle with a vertical discharge pipe at the top. The end of the vertical discharge pipe is connected to a condenser via a pipeline, and the outlet of the condenser is connected to a receiving tank. The vertical discharge pipe has a filtration section containing structured packing material. It also includes a flushing reflux pipe, one end of which is connected to the receiving tank, and the other end of which is positioned above the structured packing material. The flushing reflux pipe can return the OA solvent oil from the receiving tank to the structured packing material to flush it. This device can further reduce the colloidal content in the distilled OA solvent oil.
