Abstract
The invention discloses a special device for oil-water two-phase intermittent extraction and an extraction method thereof. The special device comprises a condenser and an extraction tank, wherein the condenser is positioned above the extraction tank, and the extraction tank is communicated with the oil phase outlet of the condenser; the oil phase outlet of the extraction tank is communicated with a distillation still, and a packed tower is communicated with the top of the distillation still; and the oil phase outlet of the packed tower is communicated with the oil phase inlet of the condenser. When the device is used for oil-water two-phase intermittent extraction, an oil phase solvent is added into the extraction tank containing water phase organic matters from the bottom of the extraction tank, and the oil phase solvent rises to a water phase liquid level while the organic matters are dissolved into the oil phase solvent. After an oil phase solvent liquid level reaches an overflow port, the oil phase solvent dissolved with the organic matters enters the distillation still to be distilled, the oil phase solvent is recycled again after vaporization, and the organic matters are preserved in the distillation still.
