Description
Technical Field
The utility model relates to the field of medical equipment, in particular to an air guide curtain for a clean room.
Background
The air supply ceiling is a core device for ensuring cleanliness and airflow organization so as to provide vertical one-way clean air airflow with balanced flow velocity. Since the local cleaning device is often in an environment with a low degree of sterility, the sterile area (main flow area) exchanges energy with the air in the peripheral area during the air supply process, so that the inner sterile area is easily affected by the environment.
Because the air current only passes through the local area and has larger space around, the air current can not be provided in a centralized way and is easy to disperse, so that the phenomena of turbulence and turbulent flow occur, the utilization rate of the clean air current is reduced, the air supply replacement and dilution functions of the core area are slowed down, and the energy consumption is caused. And the air flow velocity of the air supply at the boundary can be gradually attenuated along with the descending distance, so that the air flow attenuation is slowed down by the air flow velocity of the air supply in the main flow area in the prior art, the air speed at the outlet of the ceiling must be increased, but if the air flow velocity is increased, the air speed is too high, the obvious blowing feeling is caused, and even a whistle or larger noise is caused.

In order to achieve the purpose, the utility model adopts the technical scheme that: an air guide curtain for a clean room is arranged in the clean room, an air supply ceiling is installed at the top of the clean room, an annular air groove communicated with an air supply unit is formed in the peripheral edge of the air supply ceiling, a plurality of air outlet holes are formed in the lower end face of the annular air groove at intervals and used for sending clean air from the air supply unit into the clean room along the vertical direction, and therefore a main flow area surrounded by clean air flow is formed under the air supply ceiling;
the air supply unit further comprises a shell, an air inlet arranged at one end of the shell and an air supply outlet arranged at the other end of the shell, wherein a filter, a heat exchange device and a fan are arranged in the shell.
The further improved scheme in the technical scheme is as follows:
1. in the above scheme, the filters are provided with 3 levels, and at least one filter in each level of filters is arranged between the heat exchange device and the fan.
2. In the scheme, the air outlet is provided with the polypropylene nozzle.
3. In the scheme, the air outlet speed of the air outlet hole is 2-3 m/s.
4. In the above scheme, the air supply speed of air supply smallpox and the air-out speed ratio of exhaust vent are 1: 8 to 12.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the air guide curtain for the clean room can form an effective barrier to shield the external pollution of the main flow region while ensuring the clean and stable air supply quality, ensures the cleanliness and stability of the air in the main flow region in the long-time use process, and can also greatly improve the utilization rate of clean air flow.
