Definitions

  • the present invention relates to a method of operating a self-disinfecting odor trap assembly for installation in a sewer.
  • An odor trap is usually a piece of pipe, which holds by its shape a certain amount of the influent liquid as an odor barrier in the pipe system. All inflowing germs find in this barrier fluid ideal development conditions and multiply explosively. The contamination of the barrier liquid increases steadily. In addition, a highly contaminated biofilm of all existing germs develops on the walls of the tube inside and outside the barrier fluid. The air column above the barrier fluid inside the odor trap is also heavily contaminated by the biofilm. The inflow of liquids into such a contaminated odor trap leads to the following problems. On the one hand, an amount of contaminated air equivalent to the volume of the penetrating liquid quantity is thrown out of the odor trap back into the room at high speed.
  • the DE 27 47 992 A1 and the US 3,175,567 show a cleaning and disinfection of siphons using ultrasound. According to the US 6,666,966 B1 In addition, a non-stick layer is provided in the siphon.

  • Such solutions are inter alia in the DE 92 14 542 U1 and in the EP 1 295 585 B1 shown. In this way, the barrier liquid is disinfected.
  • the directly sprayed areas of the odor trap are disinfected, since the sprayed disinfectant does not reach all areas of the odor trap.
  • a large amount of concentrated disinfectant is needed, which is both expensive and environmentally disadvantageous.
  • the EP 0 514 636 A2 describes a method for the vapor deposition of rooms or thermal disinfection of surfaces, in particular of closed flow-through spaces.
  • the method utilizes a heated, mist-like medium, which is passed as a flow through the rooms to be disinfected.
  • a heated stream of air or gas is generated in which either steam or an aerosol of water and a disinfectant is introduced.
  • the nebulous medium is applied with a slight overpressure on the surfaces to be disinfected.
  • a device which comprises a connected to a supply line housing.
  • the housing communicates with a fan.
  • a heater for heating forced air is arranged.
  • a spraying device for producing fine liquid droplets opens into the housing in the region of the heating device.
  • the AT 391 934 B shows a degermination device for air ducts, pipes u. ⁇ .
  • a disinfectant is atomized by an ultrasonic nebulizer in the smallest aerosols up to 0.3 microns and guided by a blower to the sites to be sterilized.
  • the finely atomized disinfectant sweeps the surfaces to be sterilized and condenses, as the surface temperature of the channels is below the dew point of the air-sterilization mixture.
  • the air sucked in by the fan is heated by an air heater to about 35 ° C.
  • the sewer sections to be sterilized can be shut off with shut-off devices.
  • the air-sterilization mixture is fed through flexible lines or hoses via a connection to the degerminator and further enriched with the disinfectant in the ultrasonic nebulizer and kept in circulation until the required concentration is reached in the channel.
  • a self-disinfecting odor trap is known.
  • the arrangement described therein comprises a conventional odor trap with a closure liquid contained therein, a public address and vibration system of any frequency and a system for heating the interior of the odor trap.
  • the interaction of both systems is controlled by an appropriate regulation so that during use a cleaning and disinfection of the odor trap can be ensured.
  • this solution is relatively expensive; both in the realization, as well as in the later operation.
  • the WO 92/16243 A1 shows a method for disinfecting pipe systems sanitary systems, in which a heated fog-shaped flowable medium is generated and passed through the pipe system.
  • the object of the present invention is to provide a method for operating a self-disinfecting odor trap arrangement, which enables automatic and permanent disinfection during operation, whereby a comparatively small quantity of disinfectant is required for disinfection.
  • the odor trap should be simple in design, as low as possible to cause operating costs and be easy to maintain.
  • a self-disinfecting odor trap assembly to be operated according to the invention is intended for installation in a sewer pipe.
  • the sewer line is used to remove non-permanently flowing wastewater from a room to the outside of the room.
  • the odor trap prevents odors from entering the room; even in those periods in which no wastewater flows.
  • the room is preferably a room to which increased hygienic requirements are placed, for example a room in a hospital, such as an operating room.
  • the odor trap assembly initially comprises an odor trap with a first tube section formed as a downpipe.
  • the property of the first pipe section as a downpipe is given by the fact that the first pipe section is arranged vertically or at least predominantly vertically, so that the inflowing waste water can fall down within the first pipe section and flow down due to its weight.
  • the first pipe section has on the input side a spout connection Inflow of sewage up.
  • the spout port forms the entrance for the waste water to flow into the odor trap assembly.
  • the odor trap further comprises a subsequent to the first pipe section in the flow direction of the waste water effluent secondary pipe section.
  • the second pipe section thus serves to supply the waste water in the subsequent sewer line.
  • the odor trap assembly further includes a nebulizer for creating a disinfecting nebulizer. With the aid of the nebulizer, a disinfecting agent is converted into the disinfecting agent mist.
  • the active agent mist is an aerosol in which the liquid particles of the active ingredient are dispersed in air.
  • Another component of the odor trap arrangement is a connecting line arranged between the nebulizer and the first tube section for supplying the active agent mist into the odor trap. Accordingly, the active substance mist produced in the nebulizer flows from the nebulizer through the connecting line into the odor trap.
  • the connection line opens in particular into the first tube section of the odor trap, so that the deliverable active agent mist exits in the first tube section and distributes itself there.
  • the connecting line preferably opens laterally into the first tube section of the odor trap.
  • the second pipe section can be closed by an odor-occlusive blocking means, whereby the function of the odor trap arrangement is effected as an odor trap.
  • the blocking agent prevents odors, ie gases against the flow direction of the waste water from the sewer line back get into the room.
  • the blocking means allows the waste water to flow in the direction of flow for discharging the wastewater.
  • the blocking means forms a spatial boundary for the active substance mist which can be supplied into the odor trap.
  • the blocking means forms in particular a lower boundary for the active substance mist which has entered the first tube section, so that, due to its gravitational force, it can build up as a standing active substance nebula column in the first tube section.
  • the active substance nebula column is under the prevailing air pressure in the room and therefore not under an increased pressure.
  • the active ingredient nebula column is due to their weight.
  • the drug mist is heavier than air.

  • a significant advantage of the self-disinfecting odor trap assembly according to the invention is to be seen in the fact that the disinfecting active agent mist produced with the removed nebulizer has a very large effective surface, whereby a high cleaning and disinfecting effect is ensured. Due to the blocking means there is a limitation of the pipe section to be cleaned, so that a standing active substance mist column can arise. The standing active nebula prevents a germinated column of air in this area. By condensation of the active agent mist on the adjacent inner walls of the odor trap they are also disinfected and cleaned. The contaminated aerosol produced by the inflow of liquid into the odor trap is disinfected as it passes through the active substance mist.
  • the recontamination of room air and surfaces outside the odor trap can be reliably prevented.
