Embodiment Construction

[0027] Figure 1a , 1b The first embodiment of the present invention is shown. It comprises an elongated tubular housing 10 made of a material capable of withstanding all types of fluids. The inner surface of the casing is covered with a photocatalytic layer, or the casing material can be made of a material exhibiting photocatalytic properties. One such material is titanium, where titanium dioxide is used as a catalyst. The catalytic material can also be embedded in a suitable polymer, such as polytetrafluoroethylene (PTFE), which, in addition to holding the photocatalytic material and protecting the inner surface of the housing, is also capable of reflecting light of a specific wavelength.

[0028] The housing is provided with an elongated tubular structure 12 positioned at the center of the housing. The tubular structure is made of UV light transparent material such as quartz glass. Inside the quartz tube is arranged a UV generating means 14, in this embodiment shown a l...

Abstract

The present invention relates to a device for treatment of fluids, comprising a treatment chamber having an inlet and an outlet for the fluid to be treated, elongated UV light generating means arranged inside said treatment chamber, a photo-catalytic structure arranged in said treatment chamber, that said photo-catalytic structure is a filter arranged in the flow of fluid through the treatment chamber such that the fluid flows through said filter, wherein said filter is designed generally tubular and placed adjacent and surrounding said UV light generating means for radiating said filter with UV light, thereby creating treatment radicals, and wherein said filter is placed such that the whole flow of fluid is forced through the radiated filter.

Description

【Technical field】 [0001] The present invention relates to the treatment of fluids such as water, air, and other types of gases and liquids, and the treatment of tap water in domestic water plumbing systems according to one aspect of the invention. 【Background technique】 [0002] During the cleaning of the fluid, devices that produce a photo-catalytic effect are used in some cases. It may comprise a UV (ultraviolet) generating light source capable of irradiating a fluid within a fluid-filled enclosure, thereby generating ozone. In order to obtain the photocatalytic effect, a surface with photocatalytic properties is provided, such as titanium dioxide, which can convert light into free radicals by photocatalysis, or decompose ozone and generate free radicals, which are much more corrosive to organisms than ozone. [0003] For some cleaning devices working with this type of technology, a limited photocatalytic effect is obtained, which mainly relies on the photocatalytic surfa...
