TECHNICAL FIELD

[0001] The present utility model relates to the technical field of laminar flow supply air ceilings, and in particular to a uniform-flow membrane structure for a supply air ceiling.

BACKGROUND ART

[0002] A laminar flow supply air ceiling is a purification device necessarily used in modern hospital operating rooms, and is widely applied in projects such as hospital clean operating rooms, clean wards and clean animal rooms. A uniform-flow membrane is often used at an air outlet of the laminar flow supply air ceiling; the function of the uniform-flow membrane is mainly reflected in flow equalization, i.e. making the airflow coming down from the HEPA filter at the air outlet uniformly press downward in layers without forming a turbulent state, thereby better controlling the cleanliness to achieve Class 10,000, Class 1,000 and Class 100 effects. Currently, the uniform-flow membrane is mainly attached to a perforated plate at the air outlet; when replacement is required, the perforated plate has to be removed and the uniform-flow membrane scraped off, or a perforated plate has to be replaced directly, and such an operation is too environmentally unfriendly. In view of this situation, the uniform-flow membrane structure used in cooperation with the laminar flow supply air ceiling urgently needs improvement.
