Abstract
An apparatus and method for purification and recovery of an organic liquid. The apparatus includes a distillation kettle and a receiver tank connected by a distillation pipe, and a vacuum pump, wherein a vacuum storage tank is arranged between the receiver tank and the vacuum pump; the vacuum storage tank is connected to the receiver tank by a vacuum regulating pipe, a first vacuum regulating valve being arranged on the vacuum regulating pipe; and the vacuum storage tank is connected to the vacuum pump by an evacuation pipe, a second vacuum regulating valve being arranged on the evacuation pipe. By arranging a vacuum storage tank between the receiver tank and the vacuum pump, the vacuum degree in the receiver tank is regulated by the vacuum storage tank, such that the organic liquid is recovered in a sealed environment under reduced pressure.
