Definitions
- the invention relates to a self-disinfecting odor trap in sewers with a trap body and at least one light source.
- odor traps and the so-called barrier fluids contained in them can contain pathogenic microorganisms that escape into the ambient air when the odor traps are used as intended by aerosol formation.
- Self-disinfecting odor traps automatically cleanse and disinfect themselves without interrupting the blocking function of the odor trap. Thus, regardless of human influence and without additional expenditure of time and labor, sterility of the aerosols produced under normal use is guaranteed.
- Self-disinfecting odor traps based on WO 2000/053857 A1 are capable of completely killing 10 million bacteria per milliliter within 30 minutes by thermal disinfection or UV-C irradiation (7 log steps in 30 minutes) and thus sterile barrier fluids in To produce odor traps (test protocol A 13228as of 17/12/2013 of Hygiene Nord GmbH).
- These self-disinfecting odor traps consist according to the invention of an array of devices for disinfection (heat, UV-C radiation, ultrasound) and cleaning (vibration).
- heat disinfection
- Low-frequency vibration cleaning has proven to be extremely effective in clinical practice and has therefore led to a new state of the art in sanitary hygiene for high-risk clinical areas.
- the proven high hygienic effectiveness of the prior art self-disinfecting odor traps makes them more desirable also in non-high risk areas, general health and nursing homes and public areas.
- the high production, maintenance and energy costs of state-of-the-art devices speak against widespread application. These are increasingly proving to be a major economic disadvantage for widespread commercial use.
- these organic constituents serve other microbes as nutrients and, on the other hand, in the form of endotoxins and pyrogens, act directly negatively on the patient, for example triggering inflammation, when they emerge from the odor trap by aerosol formation.
- the release of toxins and pyrogens can directly lead to the injury of patients, preferably those with immunosuppressive and allergic reactions.
- self-disinfecting odor traps according to the prior art, the use of the disinfected, germ-free odor trap for the emission of these organic cell constituents by aerosol formation and their spread to surrounding areas. Particularly at risk are located in the immediate vicinity of the odor trap located drinking water outlets (faucets).
- the colonization of microorganisms on and in the drinking water outlets is substantially accelerated by the presence of nutrients that have been transported from the disinfected siphon to the relevant drinking water outlet by aerosol formation.
- the release of the organic cell ingredients in the barrier liquid also has the consequence that the barrier liquid can be colonized very quickly by microorganisms from the air of the sewer and the room air area of the relevant sanitary component, such as the sink, when not using the self-disinfecting odor trap, because these find enough organic substances in the barrier liquid as nutrients.
- the object of the invention is to provide a self-disinfecting odor trap, which no longer has the described economic disadvantages due to excessive costs and the disadvantage of accumulation of microbial cell contents in the barrier liquid during disinfection and thus both a rapid increase in the over the air in the Barrier liquid registered germs and their subsequent emission, as well as the escape of organic matter via aerosol formation prevents reuse.
- this object is achieved with an odor trap of known type by using a titanium dioxide nano-coating and devices for light activation thereof.
- the self-disinfecting odor trap according to the invention in sewers has an odor trap body and at least one light source.
- the odor seal body is provided with a titanium dioxide nano coating, wherein the titanium dioxide nano coating is activated by the light radiation of the light sources.
- the odor seal body of the self-disinfecting odor trap according to the invention consists either of materials impermeable to light, preferably metals or ceramics or of translucent material, preferably glass, quartz glass or plastic.
- the wall of the odor trap according to the invention is preferably e.g. provided with a primer layer, which improves by their hydrophilic properties, the firm adhesion of the titanium dioxide nano-coating on the hydrophobic inner wall of the odor trap.
- the disinfection and purification steps and the "oxidation of organic ingredients” are carried out on a single chemical structure, the titanium dioxide nano-coating simultaneously and with minimal expenditure of energy and control the oxidation of organic ingredients on the photocatalytically active titanium dioxide nano-coating automatically.
- the use of light-induced photocatalytic oxidation to kill microorganisms on activated nano-titanium dioxide layers described by the present invention is new for odor traps and leads in the technical implementation to a self-disinfecting trap which suffers from the disadvantages of the prior art self-disinfecting traps does not have.
- Nano coatings are characterized by very small particle sizes and maximum surface ratios.
- the titanium dioxide nano-coating is an oxidative-catalytic coating with superhydrophilic properties, which for its catalytic activity requires even additional excitation by light of low wavelength.
- the titanium dioxide nano-coating is preferably activated by UV irradiation, more preferably e.g. by light of a wavelength of 370 to 450 nm.
- the coating is only active when it is irradiated, with some post-reaction.
- the coating is only active where it is irradiated.
- the advantages of the titanium dioxide nano-coating for the self-disinfecting odor trap according to the invention lie in the simultaneous sequence of the three reaction steps:
- the titanium dioxide nano-coating is chemically modified by doping with chemical additives, for example with metal ions, so that light radiation with wavelengths above the UV-A range can also be used as activating radiation.
- the light sources for activating the titanium dioxide nano-coating are arranged either inside or outside the odor trap body. Suitable light sources that emit UV-A radiation are, for example, LED lamps, LED spotlights and full-spectrum daylight lamps.
- the application of nanotechnology for odor traps initially precluded the complex geometry of the odor traps, the necessary availability of light radiation of defined wavelengths and energy contents, as well as the abrasive effects of wastewater and barrier fluid.
- Odor traps through their geometry and the use of different materials, make it impossible to apply best practices for producing highly active titanium dioxide coatings such as cold spraying, plasma coating, electrodeposition, spincoating, thermal oxidation in an oxygen atmosphere and others. Therefore, a modified sol-gel method is used, which allows the uniform and abrasion largely resistant coating of odor traps.
- the modified sol-gel process allows uniform and abrasion-resistant coating of the odor traps.
- the modified sol-gel process is dip-coated, which must be repeated several times (e.g., up to 15 times) due to the geometry of the odor trap and the high abrasion resistance requirements.
- the new layer is e.g. Dried for 1 h at 130 ° C and e.g. after each fifth dipping operation, a thermal treatment e.g. carried out at 250 ° C. This process leads to a highly active, very abrasion-resistant coating.
- the special geometry of odor traps also requires an optimization of the installation of the LED lights to ensure a uniform energetic loading of the titanium dioxide layer.
- UVA LED lights Due to the geometry of the odor trap, it is preferred to use a plurality of UVA LED lights to allow uniform irradiation of the coated inner wall of the odor trap.
- Investigations were carried out to increase the disinfecting capacity ( number of killed bacteria per ml per time unit).
- surface enhancers are incorporated into the odor trap according to the invention.
- One or more surface enhancers of opaque material or translucent materials are then preferably arranged in the odor trap interior, which are provided on one or both sides with a titanium dioxide nano-coating, preferably the opaque material is metal or ceramic and the translucent material is glass, quartz glass or Plastic.

- the shape of the surface enhancer may be different, being shaped to result in an increase in the surface area provided with an active titanium dioxide nano-coating.
- the shape of the bruisenveriererers is also such that the hydraulic cross section thereof remains largely constant by the introduction into the odor trap and thus its hydraulic properties are changed as little as possible.
- the surface enhancer also serves during the use of the odor trap to convert laminar flow into turbulent and thus increase the reaction rate (disinfection capacity).
- Non-pathogenic Gram positive (Staphylococcus aureus) and Gram negative (Pseudomonas aeruginosa) bacteria were used in the laboratory studies.
- the introduction of baffles is preferably carried out in odor seal bodies of translucent material, preferably glass.
- the baffles, whose surfaces are provided with a titanium dioxide nano-coating, are incorporated in the odor trap interior for the purpose of increasing the available disinfecting capacity.
- baffles devices that serve as "flow baffles" and are made from the wall material of the reactor, typically by pushing inward, are used to convert laminar or rotational flows into turbulent flows, thereby enhancing the mixing of the reactants and increasing the flow rate
- the baffles are preferably formed by invaginations of the wall of the odor trap
- the disinfection of the barrier liquid in the odor trap interior takes place by touching the microorganisms to be killed with the active titanium dioxide nano coating.
- the described investigations showed that the effectiveness of the disinfection and cleaning can be increased both by the creation of the largest possible active surface in the odor trap interior, for example by surface enlarger, as well as by movement of the barrier liquid, for example by agitators.
- the movement of the barrier liquid is preferably carried out by means of stirring, electromagnetic oscillator or combinations thereof.
