Abstract:
An ultraviolet water disinfection reactor for installing in an existing water pipeline, wherein the existing water pipeline is cylindrically-shaped and has an axial direction of flow and is divided so as to form a pair of ends that are axially aligned with each other and which face each other, and wherein each end of the pair of ends formed by dividing the existing water pipeline has an inner diameter and a flange that extends circumferentially therearound and radially outwardly therefrom and which is provided with a plurality of throughbores that extend axially therethrough and which are spaced circumferentially therearound, said reactor comprising:a) a body; b) a plurality of Quartz sleeves; and c) a plurality of ultraviolet lamps; wherein said body is for positioning between the pair of ends formed by dividing the existing water pipeline; wherein said plurality of Quartz sleeves extend through said body; wherein said plurality of ultraviolet lamps extend through said plurality of Quartz sleeves, respectively; wherein said body comprises a tube; wherein said tube is for positioning between the pair of ends formed by dividing the existing water pipeline; wherein said tube has an axial direction of flow; wherein said axial direction of flow in said tube is unidirectional so as to avoid a change in direction of flow; wherein said axial direction of flow in said tube is collinear with the axial direction of flow in the existing water pipeline; wherein said tube has an inner diameter; wherein said tube has an entire length; wherein said inner diameter of said tube along said entire length thereof is equivalent to the inner diameter of the pair of ends formed by dividing the existing water pipeline so as to provide a smooth transition from the existing water pipeline to said ultraviolet water disinfection reactor so as to maintain a relatively smooth flow while avoiding unnecessary back flow and eddy currents for maintenance of a comparatively uniform exposure time within said ultraviolet water disinfection reactor and consequently a more uniform ultraviolet dosage as opposed to imparting a high dosage to some parts and a low dosage to other parts; wherein said plurality of Quartz sleeves extend through said tube slightly past both sides thereof and transversely to said axial direction of flow in said tube so as to be of varying lengths relative to each other depending on position in said ultraviolet water disinfection reactor; wherein said plurality of ultraviolet lamps extend in said plurality of Quartz sleeves, respectively; and wherein said plurality of ultraviolet lamps are of varying lengths relative to each other.
