Abstract
This utility model relates to the field of fatty acid ester purification technology, and in particular to a negative pressure distillation column for fatty acid ester purification. The technical solution includes a column body, with an exhaust pipe for gas discharge and a discharge pipe for material discharge at the top and bottom of the column body, respectively. A feed pipe is located on one side of the column body. The column body contains multiple trays for providing a gas-liquid mass transfer environment. Multiple flow guides for optimizing gas-liquid distribution are located on the top of each tray. Two of the trays are equipped with vortex-shaped flow guides to improve the uniformity of gas-liquid distribution. The flow guides are truncated cone-shaped, with multiple air holes on the top and multiple flow guide holes on the sidewalls. This utility model, through the arrangement of the flow guides and vortex-shaped flow guides, enables more thorough contact and mixing of gas and liquid on the trays, improves the uniformity of liquid distribution on the trays, enhances gas-liquid mass transfer efficiency, and facilitates more effective separation of the components of the fatty acid ester.
