Device comprising a source for emitting ultraviolet light

摘要

A device (1) comprises a source (20) for emitting ultraviolet light, an inlet (30) for letting in fluid to the device (1), an outlet (40) for letting out fluid from the device (1), and means (51, 52) for performing a straightening action of a flow of fluid through the device (1). The flow straightening means comprise at least one flow straightening element (51, 52) having inlet openings for letting in fluid at one side and outlet openings for letting out fluid at another side, wherein each inlet opening is in communication with a plurality of outlet openings, and wherein the element (51, 52) comprises a maze of randomly arranged, interconnected holes. In such a structure, a water element that is moving from one side of the element (51, 52) to another side may take one of various paths, as a result of which variations in inlet conditions can be dampened.

主权项

1. A device, comprising:
a source for emitting ultraviolet light, an inlet for letting in fluid to the device, an outlet for letting out fluid from the device, and means for performing a straightening action on a flow of fluid through the device, wherein the flow straightening means are arranged in a fluid path from the inlet to the outlet, and wherein the flow straightening means comprise an inlet flow straightening element arranged at an inlet area of the device having a first plurality of inlet openings for letting in fluid at one side (A) and a first plurality of outlet openings for letting out fluid at another side (B), an outlet flow straightening element arranged at an outlet area of the device having a second plurality of inlet openings for letting in fluid at one side (A) and a second plurality of outlet openings for letting out fluid at another side(B), wherein said first plurality of inlet openings is in fluid communication with said plurality of said first outlet openings, wherein said second plurality of inlet openings is in fluid communication with said second plurality of outlet openings, wherein the inlet flow straightening element and the outlet flow straightening element each comprise a maze of randomly arranged, interconnected holes for realizing a plurality of randomly arranged fluid passages through the respective elements, wherein the element is arranged for performing a flow straightening action at one of an inlet area and an outlet area of the device, and wherein the inlet flow straightening element is arranged at a position for shielding at least one area of the device from the ultraviolet light that is emitted by the ultraviolet source during operation of the device, and wherein the outlet flow straightening element is arranged at a position for shielding at least one other area of the device from the ultraviolet light that is emitted by the ultraviolet source during operation of the device.
