Abstract
An apparatus and method for mixing at least one fluid flowing through a fluid system using ultraviolet light to control organisms. Ultraviolet lamps are positioned in the fluid flow and arrays of triangularly shaped mixing elements are arranged at spaced intervals along the length of each lamp, wherein the plurality of arrays of triangularly shaped mixing elements create four vortices surrounding each elongated member forming a square array of vortices.
Claims18
An apparatus for mixing at least one fluid flowing through a fluid system, comprising:
- an array of elongated members wherein each elongated member is horizontally aligned with elongated members in adjacent columns and vertically aligned with elongated members in adjacent rows of elongated members, and wherein the axis of each elongated member is substantially aligned with the direction of fluid flow;
- and
- a plurality of pairs of triangularly shaped mixing elements arranged at spaced intervals along the length of each elongated member, each pair of triangularly shaped mixing element being arranged such that the longest side of each triangularly shaped mixing element is parallel and adjacent to the longest side of the other triangularly shaped mixing element in the pair.
A method for mixing at least one fluid flowing through a fluid system:
- submersing an apparatus in the fluid flow, wherein the apparatus comprises:
- an array of elongated members, wherein each elongated member is horizontally aligned with elongated members in adjacent columns and vertically aligned with elongated members in adjacent rows of elongated member, and wherein the axis of each elongated member is aligned with the direction of fluid flow;
- a plurality of pairs of triangularly shaped mixing elements arranged at spaced intervals along the length of each elongated member, each pair of triangularly shaped mixing element being arranged such that the longest side of each triangularly shaped mixing element is parallel and adjacent to the longest side of the other triangularly shaped mixing element in the pair.
