Abstract
The device is of the frustum dispersion type having a housing forming a conical cavity, sealed at its large end, tapering to a discharge orifice at the other end. There is a fluid inlet, which tangential to the cavity near the sealed end. There is a hollow, tapered helix cut cone shape in the center of the cavity, affixed to the sealed end, with the point thereof axially aligned with the discharge orifice to help enable the continuous swirling motion of the contained fluid and to act as a gas inlet port to start the formation of a gas vortex. As fluid in the cavity approaches the discharge orifice, it is accelerated because of the reduction of area inside the cavity as it tapers. The change in specific gravities between the fluid and the gas causes a swirling centrifugal force on the liquid and a centripetal inner swirling of the gas. The result is at the point of discharge, the fluid is heavily loaded with small bubbles of gas.
