ULTRAVIOLET STERILIZER, AND ULTRAVIOLET IRRADIATION APPARATUS

摘要

To provide an ultraviolet sterilizer capable of enhancing illumination intensity of ultraviolet rays even at the vicinity of the center of a treatment passage that is remote from a luminous element.SOLUTION: An ultraviolet sterilizer includes a passage tube having an interior straight treatment passage, a luminous element emitting ultraviolet rays, and a reflector having a reflection plane for reflecting the ultraviolet rays emitted from the luminous element to focus on the passage tube. A fluid flowing in the straight treatment passage is irradiated with the ultraviolet rays and sterilized in the ultraviolet sterilizer.SELECTED DRAWING: Figure 1
