Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil refining technology, and in particular to a high-efficiency, energy-saving, emission-reducing soap removal device. Background Technology
[0002] Acidified oil refers to oil obtained by acidifying fatty acid soaps (i.e., oil residue / soap stock), a byproduct of oil refining. Acidified oil is essentially composed of free fatty acids, unacidified fatty acid glycerides, and impurities. The production process of acidified oil generates numerous byproducts, and the content of these byproducts is an important indicator of the quality of the acidified oil. Since most of these byproducts are highly water-soluble, they are typically removed from the acidified oil through washing.
[0003] Traditional acidified oil washing methods involve mixing the acidified oil to be washed with water. A mixing tank with an agitator thoroughly stirs the oil and water, dissolving the byproducts of the acidified oil in the water, thus achieving the washing process. However, this method requires prolonged stirring, resulting in slow washing efficiency and hindering factory production. Furthermore, in practice, excessive stirring can lead to the formation of a water-in-oil mixture, making it difficult for the byproducts to fully dissolve, thus reducing the final washing effect. Additionally, existing washing equipment lacks a heating device for the washing water, typically using cold water, while warm water washing is more effective. Utility Model Content
