Constant-radial-flow stable pressure clean room air supply system

Abstract

The invention discloses a constant-radial-flow stable pressure clean room air supply system which comprises an air deflector, a slow flow layer, a filter screen layer and a flow equalizing plate. The air deflector is formed by splicing a plurality of grating plates. Positioning pieces are arranged on the front side of each grating plate in a protruding mode. Installation grooves are correspondingly formed in the rear side of each grating plate. The positioning pieces of each grating plate are inserted into the installation grooves of the adjacent grating plate. The slow flow layer is arranged at the lower end of the air deflector and is of a hollow bracket structure. The filter screen layer is arranged at the lower end of the slow flow layer, and the periphery of the filter screen layer and the periphery of a clean room are sealed. The flow equalizing plate is arranged at the lower end of the filter screen layer in an attached mode and arranged at the upper end of the clean room in a covering mode. The gridding density of the air deflector is gradually decreased from the center to the periphery. The air deflector with the gridding density being gradually deceased from the center to the periphery is adopted, the flow speeds of air flow in all positions of the air deflector are equalized, the technical problem that vortexes are generated in the clean room is solved, and the indoor cleanliness level is improved.

Description

technical field

[0001] The invention relates to the technical field of clean rooms, and more specifically, the invention relates to a constant radial flow and pressure-stabilized clean room air supply system. Background technique

[0002] Clean room refers to the reduction of particulates, harmful air, bacteria and other pollutants in the air to below the specified indicators within a certain space, and the indoor temperature, humidity, cleanliness, air velocity and air distribution, noise vibration and lighting, static electricity, etc. A room specially designed to control within a certain range of needs. The clean room occupies a pivotal position in modern production technology, but in the existing technology, the air intake system of the clean room is not well sealed, and the air intake without filter leakage leaks into the room from the air intake system, affecting the cleanliness of the room grade.

[0003] At present, the airflow distribution in many clean rooms is u...
