Document Type and Number:
WIPO Patent Application WO/2021/129322
Kind Code:
A1
Abstract:
Disclosed are an organic liquid purification and recovery device and method. The device comprises a distillation still (1) and a receiving tank (2) that are connected by means of a distillation tube (102), the device further comprises a vacuum pump (4), wherein a vacuum storage tank (3) is arranged between the receiving tank (2) and the vacuum pump (4), the vacuum storage tank (3) is connected to the receiving tank (2) by means of a vacuum adjusting pipe (203), a first vacuum regulating valve (6) is arranged on the vacuum adjusting pipe (203), the vacuum storage tank (3) is connected to the vacuum pump (4) by means of a vacuumizing pipe (304), and a second vacuum regulating valve (7) is arranged on the vacuumizing pipe (304). By arranging the vacuum storage tank (3) between the receiving tank (2) and the vacuum pump (4), the vacuum degree of the receiving tank (2) is adjusted by means of the vacuum storage tank (3), such that the organic liquid is recovered in a reduced-pressure sealed environment; and the vacuum pump (4) is intermittently started and not continuously operated, such that the vacuum pump (4) is prevented from being directly continuously vacuumized, and thus waste of the organic liquid and environmental pollution caused by the fact that the organic liquid is pumped out during continuous vacuumizing of the vacuum pump (4) is avoided.
