Ultraviolet lamp assembly for water purification

An apparatus for the treatment of water comprising:

• an elongated substantially cylindrical pressure vessel having a longitudinal axis comprising a distal end and a proximate end;
• said proximate end comprising a circumferential mouth across the diameter thereof;
• an ultraviolet light disposed within said pressure vessel coaxially with respect to the longitudinal axis of said pressure vessel and extending substantially the length thereof, whereby the terminus of a first end of said ultraviolet light protrudes slightly beyond said mouth;
• said distal end comprising an inlet tube disposed adjacent a second end of said ultraviolet light;
• said proximate end comprising an outlet tube disposed adjacent said first end of said ultraviolet light;
• said inlet tube having a larger diameter than said outlet tube;
• said inlet tube being spaced apart from said outlet tube by a distance at least 2.5 times and no greater than 2.75 times the average diameter of said pressure vessel;
• whereby said vessel, said inlet tube and said outlet tube provide a continuous passage therethrough;
• said inlet tube further comprising a discharge end and a side discharge port;
• a means for deflecting water disposed within said vessel adjacent said discharge port adapted to deflect water radially from said side discharge port in one direction only;
• said deflector means being further adapted to define a substantially arcuate passage of fluid discharged from said discharge port in only one direction commencing on a substantially perpendicular plane with respect to the longitudinal axis of said vessel and spiraling in a direction toward said outlet tube following a substantially parallel plane with respect to the longitudinal axis of said vessel;
• a baffle for regulating flow of fluid within said passage disposed within said vessel downstream from said inlet tube on a substantially perpendicular plane with respect to the longitudinal axis of said vessel and extending substantially across the entire cross section thereof between said inlet tube and said outlet tube;
• said baffle comprising a disk having a longitudinal axis disposed in coaxial relationship with the longitudinal axis of said vessel;
• said baffle further comprising a plurality of longitudinal baffle ports having axes in parallel relationship with respect to the longitudinal axis of said baffle and disposed radially therefrom;
• and
• whereby said baffle ports provide a plurality of fluid passages within said passage for directing fluid flowing therethrough, to and around said ultraviolet light and for providing uniform rate of fluid flow thereby optimizing fluid contact time to ultraviolet light for the sterilization of microorganisms laden therein.

An apparatus for the treatment of water comprising:

• a substantially cylindrical elongated pressure vessel having inlet and outlet tubes disposed adjacent opposing ends of said pressure vessel in fluid communication therewith;
• said inlet tube having a larger diameter than said outlet tube;
• said inlet tube being spaced apart from said outlet tube by a distance of at least 2.5 times and no greater than 2.75 times the average diameter of said pressure vessel;
• said inlet tube comprising a side discharge port;
• an ultraviolet light disposed within said pressure vessel extending substantially the length thereof;
• said ultraviolet light comprising an elongated lamp tube;
• said lamp tube having disposed therein a single end cap;
• said end cap comprising a proximate portion and a distal portion;
• said proximate portion of said end cap having disposed therein and extending therefrom a set of primary electrical connector pins and a set of secondary electrical connector pins;
• said lamp tube comprising on its proximate end and located distally from said primary connector pins two electrical leads each having one end electrically connected to said primary connector pins and having the other end connected to an electrical filament;
• said lamp tube further comprising on its distal end a second set of filament leads disposed and fused therein with one end of each lead extending along the outside surface of said lamp tube in the direction of said single end cap with each of said leads connected to said secondary connector pins;
• and
• said distal portion of said single end cap and said lamp tube and said first filament leads and said second filament leads being sealingly disposed within an ultraviolet light permeable closed-ended sleeve.
