Embodiment Construction

[0023] figure 1 A device 1 designed for disinfecting water is shown. For the sake of completeness, it is noted that the device 1 is described as an example of a number of devices feasible within the scope of the invention, including air purification devices and devices for sanitizing liquids other than water.

[0024] The water disinfection plant 1 comprises a reactor 10 , ie a container with an inner space 11 in which the water disinfection process takes place during operation of the plant 1 . The reactor 10 has an inlet 12 for the entry of water to be treated and an outlet 13 for the exit of the water. Furthermore, the water disinfection device 1 comprises a lamp 20 for emitting ultraviolet light, which is arranged inside the reactor 10 . In the example shown, the lamp 20 has an elongated shape and has a central position in the reactor 10 , which is the most practical position as this allows efficient use of the entire surface of the lamp 20 .

[0025] The lamp 20 may be ...

Abstract

A device for subjecting a fluid to a disinfecting treatment by exposing the fluid to ultraviolet light comprises a reactor (10) having an inner space (11) in which means (20) for emitting ultraviolet light are arranged, an inlet (12) for letting fluid into the inner space (11), and an outlet for letting out fluid from the inner space (11). The light emission means (20) comprise a single electrode, wherein a wall (14) encompassing the inner space (11) is adapted to function as an electrode and comprises electrically conductive material, and wherein the device further comprises means (30) which also comprise electrically conductive material, and which are arranged for locally enhancing the electrical conductivity in a space between the reactor wall (14) and the light emission means (20). By applying these means (30), it is achieved that the disinfecting effect of the ultraviolet light treatment can be improved.

Description

technical field [0001] The present invention relates to a device for subjecting a fluid to sterilizing treatment by exposing it to ultraviolet light, said device comprising a reactor having an inner space, an inlet for allowing the fluid to enter the inner space and for passing the fluid from An outlet from the inner space, wherein means for emitting ultraviolet light is arranged in the inner space, wherein the light emitting means comprises a single electrode, and wherein the walls surrounding the inner space are adapted as electrodes and comprise conductive material. Background technique [0002] Apparatus for subjecting fluids to disinfection by exposing them to ultraviolet light (UV) is known. For example, for the microbiological disinfection of drinking water it is known to use sources / lamps for emitting so-called UV-C radiation emitting ultraviolet light having a relatively short wavelength in the order of 100 to 280 nm. For domestic applications, the UV-C source is u...
