PHOTOCHEMICAL REACTOR, LUMINESCENT SCREEN AND PHOTOCHEMICAL PROCESSING SYSTEM

摘要

The invention relates to a photochemical reactor (12). The invention further relates to a photochemical processing system. The photochemical reactor comprises a vessel (20) comprising the fluid (30), a light source (40) for generating UV-radiation (UVl) and emitting it towards the fluid, and a luminescent material (50) arranged between the light source and the fluid for converting at least part of the UV-radiation emitted by the light source to further UV-radiation (UV2) having an increased wavelength compared to the UV- radiation. The luminescent material is removably connected to the photochemical reactor and is separate from the light source. By having the luminescent material removably connected to the photochemical reactor, separate from the light source, the luminescent material may be exchanged with new luminescent material if the current luminescent material has degraded.
