Abstract
A device for irradiating flowing liquids and/or gasses with ultraviolet (UV) light comprising a casing with in and outlet apertures and one or more UV light sources wherein the light sources are within protective tubes. The light sources are arranged such that the maximum radiation occurs along the axis of flow of the liquid and/or gasses.
Claims15
A device for irradiating a flowing liquid or gas medium with UV light, comprising
- a housing with an upstream entry opening for inflowing medium and with a downstream exit opening for out-flowing medium;
- and
- one or several UV light sources arranged in protective pipes which are permeable for UV light, said UV light sources located within said medium and arranged in such a way that the UV light radiation is directed and its maximum extends in the flow direction of the inflowing medium and the outflowing medium;
- wherein the UV light sources have a flat oval cross-section;
- said flat oval cross-section comprising two parallel flat walls with oval walls connecting together the ends of said flat walls;
- and wherein said UV light sources emit greater than 50% of their emitted light via said flat walls, and lesser than 50% via said oval walls;
- and
- said flat walls oriented perpendicular to the direction of flow of said liquid or gas medium.

- one or several UV light sources arranged in protective pipes which are permeable for UV light, said UV light sources located within said medium and arranged in such a way that the UV light radiation is directed and its maximum extends in the flow direction of the inflowing medium and the outflowing medium;
- wherein the UV light sources for production of a directed radiation distribution and increased density of rays have a flat oval cross-section;
- said flat oval cross-section comprising two parallel flat walls a spaced distance apart with oval walls connecting together ends of said flat walls across said spaced distance;
- said flat walls oriented parallel to the direction of flow of said liquid or gas medium;
- and
- protective pipes with light-deflecting ribbing or light reflectors that so surround said flat walls and said oval walls whereby said UV light sources emit greater than 50% of their emitted light via said flat walls, and lesser than 50% via said oval walls.
