Apparatus is disclosed for substantially reducing the momentum, velocity, or both of a first liquid that is flowing into a second liquid. The device allows one to substantially reduce or even eliminate large-scale turbulent eddies that could otherwise be produced by liquid flowing into or within a vessel, for example in a clarifier. Suitably-sized and positioned plates and baffles induce changes of flow direction in a limited volume. By the time the fluid leaves this volume, the fluid velocity is low, and turbulence is nearly or entirely eliminated. Several of the devices may be placed at different inputs within a single clarifier, and thus increase efficiency further. |

1. Apparatus for reducing the turbulence otherwise associated with the flow of a first liquid, from a pipe or hose and into a second liquid within a vessel; wherein said apparatus is adapted to be submerged within the second liquid; wherein the first and second liquids may be the same or different; and wherein said apparatus comprises:
(a) first and second rigid plates, wherein said first and second plates are about the same size and shape, except that said first plate incorporates a central hole through which the pipe or hose may pass, so that the pipe or hose is positioned to discharge the first liquid into the space between said first and second plates; (b) one or more spacers, wherein each said spacer is attached both to said first plate and to said second plate, wherein said spacers hold said first and second plates in a fixed position relative to one another and parallel to one another; (c) at least four baffles rigidly affixed to said second plate; wherein said baffles are positioned symmetrically relative to the axis that passes through the center of the hole in said first plate and that is also perpendicular to both said plates; and wherein spaces are present between adjacent baffles to allow some liquid to pass between adjacent baffles;wherein said apparatus is adapted for use as follows:
(d) when the first liquid exits the pipe or hose, the first liquid impinges upon said second plate; said second plate diverts the flow of the first liquid by about 90 degrees, from an approximately linear flow that is approximately parallel to the axis, into a radially outward flow that is approximately parallel to said second plate; and then, when the radially-outwardly-flowing first liquid impinges upon said baffles, said baffles further disperse the energy of the flow of the first liquid; so that, when the first liquid exits the space between said first and second plates, there is essentially no turbulence in the first liquid, and there is essentially no turbulence at the interface between the first and second liquids; and wherein the spaces between adjacent baffles inhibit the formation of any vortices that would otherwise tend to form within a hypothetical, otherwise-identical apparatus in which said adjacent baffles were contiguous to one another, without spaces between adjacent baffles. |
