What's the working principle of annular compressed air knife?
Here with the diagrammatic sketch and detailed introduction:
The connected compressed air flows through the inlet (1) into the ring cavity (2) through the air ring.
It then throttles and passes through the annular nozzle (3) at high speed.
The air flow rushes out at high speed along the side wall (4) of Coanda at first, and this air flow jets at an oblique angle along the side wall of the air ring.
In this way, a low-pressure area (5) will be generated in the center of one side of the air ring.
This low-pressure area will force a large amount of surrounding air to flow to the other side of the air ring together with the high-pressure air flow.
When the airflow leaves the air ring, a 360°conical circular airflow is generated.
This uniform and powerful airflow can continuously and steadily blow water, dirt and other impurities on the material (6) passing through the air ring.
