FUNCTIONAL PERMEATION EVAPORATION COMPOSITE FILM AND MODULE DEVICE

摘要

Purpose: the pervaporation combined film of a function and the module device for purifying washing liquid are more effectively provided, energy saving and difficult for separating materials solution evaporation, such as azeotropic mixture. Construction: a release type pervaporation module device includes a liquid supply module, it, which is equipped with an osmotic evaporation film and is arranged in top, increases the effective membrane area contacted with liquid, one module, it is placed in centre and has a liquid supply section and a pervaporation portion (21), an and pervaporation module (9), it is placed on lower part and has for providing an inlet part of liquid, and a discharging part (7) is used for circulating liquid and a pervaporation portion. The film being mounted on module device can be applied to the isolated technique of gas separation membrane, ultrafiltration membranes and nanofiltration membrane.
