FUNCTIONAL PERMEATION EVAPORATION COMPOSITE FILM AND MODULE DEVICE

摘要

PURPOSE: A functional permeation evaporation composite film and a module device used for purifying washing liquor more effectively are provided which economize energy and resolve evaporation difficulties for separating materials such as azeotropic mixtures. CONSTITUTION: A release type permeation evaporation module device comprises a liquid supplying module that is equipped with a permeation evaporation membrane and placed at the upper part to increase an effective membrane area that contacts with liquid, a module that is placed in the middle and has both a liquid supplying part and a permeation evaporation part (21), and a permeation evaporation module (9) that is placed at the lower part and has an inlet part for supplying liquid, a discharging part (7) for circulating liquid and a permeation evaporation part. The membrane mounted on the module device can be applied to the separation processes of gas separation membranes, ultrafiltration membranes and nanofiltration membranes.
