| Zusammenfassung: | The utility model relates to a device for effectively recovering butanol, octanol and octenal in high alcohol, which comprises a dehydrating tower, a butanol rectifying tower, a gas-liquid separation tower, an octenal rectifying tower and an octanol rectifying tower, high alcohol waste liquid enters the dehydrating tower, a liquid phase outlet of the dehydrating tower is connected with the butanol rectifying tower, a liquid phase outlet of the butanol rectifying tower is connected with the separation tower, and the octanol rectifying tower is connected with the octanol rectifying tower. A gas phase outlet of the gas-liquid separation tower is connected with the octenal rectifying tower, and a liquid phase outlet of the gas-liquid separation tower is connected with the octanol rectifying tower. The recovery rate of butanol is 75% or above, the recovery rate of octanol is 55% or above, and the recovery rate of octenal is 65% or above. The total yield of useful components in the high-carbon alcohol can reach 35% |
