Device for improved delivery of gas to fluid

摘要

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.

主权项

1. A device for diffusion of gas into liquid comprising:
an outer housing of hollow frustum shape having a central axis, said axis extending from a small diameter liquid outlet end, defining a liquid outlet opening, to a large diameter end; a liquid inlet port formed in said housing and defining a liquid inlet opening for delivery of liquid into said hollow housing; a helically cut conical member having an inner curvature positioned and affixed within the hollow center of the housing with its axis aligned with that of the hollow frustum shape such that liquid delivered into the housing forms a swirling motion around the outside of the member as it passes from said liquid inlet opening to said liquid outlet opening, said housing having a gas inlet for delivery of gas to the liquid within the housing as it moves from said inlet opening to said liquid outlet opening, and the housing being sealed at its large diameter end and the liquid inlet port being positioned adjacent said large diameter end.
