ABSTRACT:
A vortical flow type bubble separating apparatus comprises a container defining a substantially cone-shaped vortical flow chamber having a lower larger diameter end with a plurality of holes, an outer casing for receiving a liquid discharged from the vortical flow chamber through the holes, a center conduit pipe with a plurality of orifices for removing bubble containing fraction from the vortical flow chamber for discharging, an annular preliminary vortical flow passage extending at least approximately entire circumference of the larger diameter end portion of the container, a single opening defined through the peripheral wall of the vortical flow chamber and communicating the vortical flow chamber and the preliminary vortical flow passage, the opening being designed for introducing the liquid into the vortical flow chamber from the preliminary vortical flow passage in substantially tangential direction to the vortical flow chamber, and a flow guide member provided at the end of the preliminary vortical flow passage in the vicinity of the opening for guiding the liquid flow into the vortical flow chamber with little angular deflection.
