Definitions
- the invention describes an arrangement for the automatic cleaning and disinfection of odor traps in sewage pipes. Cleaning and disinfection take place automatically during the intended use and without interrupting the function of the odor trap. It takes place by means of a novel combination of electromechanical vibrations for odor traps, from vibrations of low frequency to ultrasound, heating of the interior of the odor trap and the sealing liquid and prevention of interior wall growth through an anti-fouling and antimicrobial coating.
- aerosols When liquid impacts and swirls, aerosols are formed which consist of tiny liquid droplets that also contain all the microorganisms contained in the barrier liquid. Such aerosols arise, for example, when opening the taps of wash basins in the drainage area. These aerosols then contain representatives of all of the microorganisms which are in the liquid in the siphon and in the mucus layers adhering to the inner walls.
- the aerosols formed are displaced from the cavity in the direction of the pipeline entrance by trailing liquid and thus get into the air of the room from which the waste water was introduced into the pipeline. For example, these bacteria are transferred to the hands of a person washing themselves in the sink.
- microbes together with dirt particles on the inner wall of the pipe or siphon form the well-known slimy coating. This grows, partially largely invisible to the eye, from the opening of the drain to the sink.
- the combinations of ultraviolet light and ultrasound (DE 295 09210 U1) are not described for the cleaning and disinfection of pipes and siphons, but for the cleaning and disinfection of objects in liquids.
- the combination of ultraviolet light and high temperature (DE 42 06 901 A1) is described for the treatment of the liquid in a siphon.
- the effectiveness of ultrasound on killing germs is temperature-dependent. Since the temperature of the liquid in pipes and odor traps is dependent on many factors and therefore fluctuates, the killing effect by ultrasound alone also fluctuates and therefore cannot be fully defined even with maximum exposure to sound. At room temperature, for example, the killing effect with sensibly installable ultrasound outputs (e.g. 300 - 1000 watts / liter) is only possible with relatively long sonication times (one hour and longer), while at temperatures of 50 ° C a few minutes are sufficient. At this temperature, microorganisms are not killed by the heat alone.
- interval-like sonication of the interior of the odor trap leads to the detachment of existing wall coverings, especially at higher temperatures, and at the same time prevents re-occupancy.
- the object of the invention to be described below is to describe a self-disinfecting odor trap which solves the problem of the multiplication and emergence of microorganisms from waste water pipelines with safety and reproducibility which cannot be represented by the current state of the art and which ensures maximum and always reproducible germ killing prevents the inside walls of odor traps and the escape of aerosols contaminated with living germs from pipelines and does not have the above-mentioned disadvantages of known developments.
- the self-disinfecting odor trap according to the invention the following effects are thus achieved in one apparatus:
- microorganisms of all kinds are reproducibly killed under the same conditions at a sufficiently high temperature, sufficient ultrasound intensity and a treatment time which ensures complete germ destruction during the intended use.
- a liquid-repellent and / or antimicrobial coating of the inner wall of the odor trap makes it much more difficult for microorganisms and dirt particles to become stuck and for microorganisms to multiply.
- the air in the interior of the odor trap can also be sterilized using ultraviolet light.
- the invention prevents the formation of the known dirt and microorganism coating by a special non-stick coating of the inner wall or the use of suitable material for the reaction space.
- the apparatus consists of an odor trap of known type 1 made of stainless steel or other materials, which can be provided with a non-stick coating 2, at least one apparatus for ultrasound irradiation 3, or for treatment with low-frequency electromechanical vibrations 3A, the liquid 4 and of the filling tube 5 projecting into the liquid with simultaneous temperature control 6, a coupling with a device for closing the pipe inlet opening 7, a closing membrane 8 and optionally a device for treating the air space 16 above the barrier liquid and the closing membrane 8 with light, preferably ultraviolet light 9 .
- This combination prevents dirt and microorganism deposits within the self-disinfecting odor trap and on its internals. Entered or growing germs are completely destroyed when using ultrasound.
- the ultrasound sound system consists of at least one ultrasound generator 9 and at least one ultrasound transducer 3, which is either applied to the odor trap from the outside or is introduced directly into the standing liquid.
- the liquid 4 located in the pipeline and the self-disinfecting odor trap is brought to an optimum temperature for killing the microorganisms or for inhibiting the multiplication of germs by means of a temperature control system of any type 6 and is kept there at least for the time of the ultrasound treatment.
- a temperature control system of any type 6 for this purpose, at least one thermal sensor 11 can be fitted inside or outside the reaction space.
- the apparatus can be insulated against heat radiation to the outside by means of an insulation layer 12.
- the temperature control system 6 can be installed outside or inside the reaction space.
- a light source (preferably UV lamp) 9 can be installed in such a way that the air space above the barrier layer and the aerosols contained therein are sterilized.
- sensors for the temperature 11 and the fill level 13 of the sealing liquid can be installed.
- the entire apparatus is surrounded by an outer housing 14.
- a control cabinet 15 belongs to the apparatus.
- the self-disinfecting odor trap can be instrumented in different ways in accordance with the requirements, which essentially result from the type and the germ content of the waste water and the mode of operation of the odor trap.
- the self-disinfecting odor trap is always provided with at least one ultrasonic sound system, at least one heating or thermostating device and the associated control technology.
- the self-disinfecting odor trap in the illustration (Fig. 1) in the form of a common bottle siphon, is designed with maximum instrumentation with:
- the self-disinfecting odor trap designed in this way ensures maximum safety against all those drains that are used irregularly and that have the risk of drying out in the meantime.
- the level control is the main signal generator. This means that both heating and ultrasound can only be put into operation when the fill level is sufficient.
- the heating power can be installed at any height, which means that a very short heating-up phase can be achieved.
- the thermostat control prevents the temperature required for the sound from being exceeded, even in the case of hot liquids in the odor trap at the time when the heating begins before the ultrasound treatment.
- the sealing membrane is attached directly to the part of the mechanical opening mechanism of the drain projecting into the drain pipe.
- the sealing membrane consists of a membrane of any material. This is compressed in the middle by liquid flowing into the drain. In the non-compressed state, it separates the air space above the sealing liquid from the ambient air even when the drain plug is open.
- the self-disinfecting odor trap in the illustration (Fig. 2) in the form of a common bottle siphon, is designed with maximum instrumentation with:
- the self-disinfecting odor trap designed in this way ensures maximum safety against all those drains that are used irregularly and that risk drying out in the meantime.
- the level control is the main signal generator. This means that both heating and ultrasound can only be started up when the level is sufficient.
- the heating output can be installed at any height, which means that a very short heating-up phase can be achieved.
- the thermostat control prevents the temperature required for the sound from being exceeded, even in the case of hot liquids in the odor trap at the time when the heating begins before the ultrasound treatment.
- the mechanical membrane seal is attached directly to the part of the mechanical opening mechanism of the drain projecting into the drain pipe.
- the sealing membrane consists of a membrane of any material. This is compressed in the middle by liquid flowing into the drain. In the non-compressed state, it separates the air space above the barrier liquid from the ambient air, even when the drain plug is open.
- the apparatus is functional in the following version with minimal equipment:
- the heating and ultrasound systems are switched at different times. First the heating system is switched on. When the time required to reach the sterilization temperature is reached, the heating switches off and the ultrasound switches on. The sterilization temperature is reached by designing the heating after a certain, experimentally determined time. At this point the heating is switched off and the ultrasound is switched on.
- the following version of the apparatus is functional with minimal equipment for self-cleaning and killing of microorganisms, which are already killed at temperatures around 60 ° C (Pseudomonas aeruginosa) in the version with low-frequency electromechanical vibration: Only so much heating power is installed via the heating system 6 that no temperature control via a thermostat part is necessary, because the temperature required for the disinfection is usually not exceeded or only so limited in time that evaporation losses cannot occur. Heating and low frequency public address systems are therefore switched with a time delay. Example: heating on for 4 x 3 hours per 24 hours. Sound is independent of the heating every 2 hours for 10 minutes. This variant is provided with an antimicrobial inner coating.
- Embodiment 5 is a self-disinfecting odor trap in the
- the installed heating power is selected so that the sealing liquid is heated either very quickly (higher heating power) or slowly (low heating power).
- Heating turned off.
- the temperature which is necessary for the ultrasound, is reached after a long time (30 - 60 minutes).
- the ultrasound is then switched on at the time.
- This arrangement is advantageous for frequently and regularly used drains into which liquids with higher germ contents and lower temperatures are introduced. If a high heating capacity is installed (approx. 1-3 watts / ml of barrier fluid), the barrier fluid will reach temperatures close to the boiling point of the barrier fluid within a few minutes, regardless of the starting temperature. This temperature is maintained during the time of the sonication, which can then be very short. Heating and ultrasound are switched on and off at the same time. With this arrangement, particularly stubborn spore formers are killed in a very short time. For non-spore-forming bacteria as well as yeasts and fungi, only a very short sonication time is necessary.
- Exemplary embodiment 6 represents a self-disinfecting odor trap in the form of a conventional tube siphon with minimal instrumentation, which is equipped as follows:
- the ultrasound transmitter is attached to the side wall of the odor trap by means of a transmitter block.
- Embodiment 7 represents a self-disinfecting odor trap in the form of a customary bottle siphon with minimal instrumentation (embodiment 6), the heater consisting of a heating lamp protruding into the sealing liquid.
- Embodiment 8 represents a self-disinfecting odor trap in the form of a customary bottle siphon with minimal instrumentation, the siphon body being made of material which is permeable to light radiation and the heating being carried out by a heating lamp fitted outside the odor trap.
