<p>A suction unit sets the medium coming in through the intake into movement, causing it to pass downwards through the vessel, and out through the outlet. The primary intake comprises a number of symmetrically positioned, inclinedly directed holes in the wall of the vessel, causing the formation of a swirl with straight characteristics through the vessel central, long and narrow part with avoidance of turbulence currents. The wall holes also initiate the direction of rotation of the movable medium downwards through the vessel. In the upper narrow part of the vessel is a secondary intake with hyperbolic and rotation-symmetrical shape, which is for mixing gas with the medium, and is displaceable height-wise. This secondary intake is long and narrow, and has its lower part nearest the vessel shaped hyperbolically and rotation-symmetrically. It evolves into a cylindrical tubular shape located further from the vessel.</p> |
