Why are the inlets of cyclone separators usually square? Can it be set to circular? Is the difference significant?
The cyclones in our factory are circular in shape
In simple terms, it generally depends on the volume of air that needs to be handled. For systems dealing with large volumes of air, a square-shaped inlet is usually chosen; the inlet to the cyclone is designed in a volute shape, and a flange that converts from square to circular shape is used to connect the pipeline. In cases where smaller volumes of air need to be handled, a tangential inlet can be used, in which case a circular inlet will suffice. As for the principle, you can read books on cyclone theory, which provide detailed explanations.
