Abstract
This invention relates to the field of liquid-liquid separation and discloses an apparatus and method for aromatic hydrocarbon extraction. The apparatus includes a raw material tank, a solvent tank, a mixer, and an extraction tower. The raw material tank is connected to the raw material inlet of the extraction tower, and the solvent tank is connected to the solvent inlet of the extraction tower. The mixer includes a spray section and a mixing and extraction section. In the mixing and extraction section, the raw material and solvent are broken and diffused through multiple variable diameter sections and rotated by a single helical blade. Finally, the mixing is completed in a petal-shaped turbulent mixing chamber, which effectively improves the mixing and emulsification effect of the raw material and solvent, which is beneficial to improving the extraction efficiency. The apparatus has a compact structure and low energy consumption, and is particularly suitable for aromatic hydrocarbon extraction in the fields of chemical, food, coating, and cosmetic industries.
