Abstract
A method for disinfecting a fluid includes emitting UV light into a flowing fluid pillar along its axial direction. The flowing fluid pillar is surrounded by and in contact with a fluid medium having a refractive index lower than that of the fluid to be disinfected so that total internal reflection occurs when the UV light travels within the flowing fluid pillar. Also provided is a UV disinfector for disinfecting a flowing fluid.
Claims17
A method for disinfecting a fluid, comprising:
- providing a fluid to be disinfected;
- generating a flowing fluid pillar of the fluid to be disinfected, wherein sidewall of the flowing fluid pillar is surrounded by and in contact with a fluid medium having a refractive index lower than that of the fluid to be disinfected;
- and
- emitting UV light into the flowing fluid pillar along an axial direction of the flowing fluid pillar.

A UV disinfector comprising:
- a UV light source;
- and
- a laminar flow injector comprising a housing for accommodating a fluid to be disinfected, the housing having a nozzle for generating therethrough a flowing fluid pillar of the fluid to be disinfected;
- wherein the housing of the laminar flow injector has an outlet chamber connected with the nozzle, an inlet chamber connected with an inlet of the housing, and a laminar flow enforcer located between the inlet chamber and the outlet chamber, the laminar flow enforcer helps to generate a laminar flow in the flowing fluid pillar;
- wherein the UV light source and the laminar flow injector are so configured that, when in use, UV light is emitted from the UV light source into the flowing fluid pillar and travels within the flowing fluid pillar along an axial direction of the flowing fluid pillar.
