Document Type and Number:
WIPO Patent Application WO/2018/099453
Kind Code:
A1
Abstract:
Disclosed is an oxygen enriched membrane assembly (100), comprising: a support frame (110), wherein the support frame has a first surface (111) and a second surface (112) parallel to each other and is formed with multiple airflow passages (113), the airflow passages respectively extending on the first surface (111) and the second surface (112) and penetrating through the support frame (110) and communicating the first surface (111) and the second surface (112), and the multiple airflow passages (113) together forming an oxygen enriched gas collecting cavity; and two oxygen enriched membrane layers (120) respectively laid on the first surface (111) and the second surface (112) of the support frame (110), each of the oxygen enriched membrane layers (120) being configured to enable much oxygen, with respect to nitrogen gas therein, in an airflow of a space surrounding the oxygen enriched membrane assembly (100) to permeate the oxygen enriched membrane layers (120) so as to enter the oxygen enriched gas collecting cavity.
