Acetone water absorption device with multi-stage circulating cooling reflux section

The invention discloses an acetone water absorption device with a multistage circulating cooling reflux section. The acetone water absorption device comprises an acetone water absorption unit, a refrigerator, a water cooler in a second absorption tower I, a water cooler in a second absorption tower II, a circulating absorbent water cooler at the bottom of the second absorption tower and a pipeline. A multi-stage circulating cooling reflux process is adopted for the acetone water absorption tower, on one hand, a multi-stage circulating cooling reflux section is set for the second absorption tower, the separation effect of the absorption tower is improved by reasonably distributing the circulating reflux cooling load of the absorption tower, and the total cooling load of the whole absorptionprocess is greatly reduced, on the other hand, the VLA is directly fed from the bottom of the second absorption tower. Compared with the existing acetone water absorption process that gas-liquid heattransfer before VLA enter
