FIELD: chemistry.
SUBSTANCE: device (1) comprises an ultraviolet light emitting source (20), an inlet (30) for fluid supply into the device (1), an outlet (40) for fluid removal from the device (1) and current rectifiers comprising at least one rectifying element (51, 52) having inlet holes for fluid supply on one side and outlet holes for fluid removal on the other side. Each inlet hole is connected to a number of outlet holes, whereas rectifying element (51, 52) comprises a labyrinth of randomly arranged interconnected holes.
EFFECT: invention enables reducing the number of fluid flow paths from the inlet to outlet that enables damping inlet conditions variations.
