Definitions

  • a device and a method for disinfecting media-carrying channels and the use of the device are described.
  • Media-carrying channels are channels in which a medium is carried.
  • a medium can be carried in the channels in liquid or gaseous form.
  • Media-carrying channels can be, for example, sewers, ventilation channels and channels for supplying and / or removing substances during the manufacture or processing of products of the most varied of types and for supplying and / or removing products.
  • disinfection must be carried out at regular intervals in addition to cleaning.
  • the intervals between such disinfections in conjunction with or without cleaning can be minutes, hours, days, weeks, months or even years.
  • the type and quantity of the processed meat e.g. beef, pork, poultry, etc.
  • the prevailing climatic conditions temperature, humidity, etc.
  • the disinfection, drains and sewers are disinfected, which are located in the rooms in which the meat or meat products are processed and stored.
  • liquids and impurities e.g. blood, leftover meat, etc.
  • the gullies and channels thus offer an ideal basis for bacteria such as Listeria.
  • bacteria such as Listeria.
  • cleaning which is not able to eliminate the bacteria, is followed by disinfection.
  • Bacterial contamination can also occur in ventilation ducts of buildings or vehicles as well as in ducts for the supply and removal of substances and products of various kinds.
  • Disinfection is usually carried out by pouring in a disinfectant or by injecting one Disinfectant into a channel using a spray device.
  • the object is therefore to provide a possibility of disinfecting media-carrying channels of various designs, the required amount of disinfectant being low and complete disinfection being able to be achieved.
  • a device for disinfecting media-carrying channels at least having a nozzle and an adapter, the adapter surrounding a space and having a first and a second opening, the adapter being connected to the nozzle via the first opening, the nozzle has at least one connection for supplying a disinfectant, the nozzle has an outlet opening, via which the disinfectant supplied can be introduced into the space spanned by the adapter, and the adapter can be sealingly attached to a channel opening via the second opening.
  • media-carrying channels and gullies of various designs can be completely disinfected, the entire surface of the media-carrying channels being misted or wetted by the disinfectant introduced, ie coming into contact with the disinfectant.
  • What is essential for the device, among other things, is the design of the adapter that spans a space.
  • the adapter is placed on a channel opening via its second opening, which can be larger than the first opening.
  • the adapter can be attached to a lateral channel opening or upside down to a channel opening via its second opening.
  • the adapter is placed on or attached to the channel opening in such a way that a seal against the environment surrounding the device and the adapter is achieved and the disinfectant introduced via the nozzle into the space spanned by the adapter cannot get out of the space of the adapter , but only enters the canal through the canal opening.
  • the channel itself can have further channel openings which then have to be covered when the disinfectant is introduced, preferably in the form of a mist, wherein in further embodiments the mist can be introduced as a moist or dry mist.
  • cover bells can be used, which seal the channel openings.
  • further devices can also be applied to channel openings of a channel system.
  • the number of devices to be used for the complete disinfection of a sewer system depends on the amount of disinfectant to be introduced via the nozzle and the length of the sewer system and the design of the sewer system. For example, in the case of a very branched canal system, it may be necessary to place several devices on corresponding canal openings in order to ensure complete disinfection of the canal system. Furthermore, the number of devices for cleaning a sewer system and the use of a device must be determined in accordance with the diameter and length of the sewer system and the delivery rate of a device that ensures that the mist with the disinfectant from the nozzle into the adapter and the channel is sprayed or arrives.
  • the device can be designed in such a way that the nozzle can be exchanged so that a larger amount of disinfectant per unit of time and / or required throwing distances of the disinfectant can be achieved.
  • the introduction of a mist into the channel to be cleaned has the advantage that disinfection can take place over several levels.
  • Conventional disinfection with a disinfectant that is poured into a channel does not allow disinfection across, for example, two levels because, for example, the disinfectant introduced into an upper level would escape through channel openings in the level below.
  • it would then be necessary to shut off the channel so that the disinfectant cannot immediately drain off via a sewage system or the like.
  • the disinfectant would escape and thus not complete disinfection.
  • the device described and the associated disinfection allow the advantage that the device can simply be placed on a channel opening via the adapter and a seal is thereby already achieved.
  • a disinfectant which is introduced as a mist, can be distributed in the entire sewer system without the disinfectant escaping or the disinfectant flowing off quickly, which would disadvantage the disinfection.
  • the disinfectant can be introduced as a mist via the nozzle, for example in a pressure range of approximately 1 bar to 6 bar.
  • the disinfectant is supplied to the nozzle via the connection for supplying a disinfectant.
  • the connection can be connected via at least one line to a device which supplies the disinfectant to the nozzle with a presettable and variable pressure.
  • the nozzle is connected to the adapter via the first opening.
  • the connection is designed in such a way that no disinfectant can escape through the first opening when the device is in operation.
  • the first opening can be connected to the nozzle via an intermediate piece, the intermediate piece being fixedly or detachably connected to the nozzle.
  • the adapter can take various forms.
  • the adapter can be cylindrical, pyramidal, be cube-shaped, cuboid, conical, prism-shaped or have a shape formed from the above shapes.
  • the nozzle is designed so that various disinfectants can be introduced, the disinfectant neither attacking nor damaging the nozzle or the adapter.
  • the nozzle is designed in such a way that a mist is generated in the area of the outlet opening and a corresponding ejection and throw are achieved.
  • the nozzle itself is designed as a mist nozzle.
  • the disinfectant used is selected according to the type of contamination or pollution of the sewer, the material of the sewer and the concentration or composition of the disinfectant, with the disinfectant introduced as a mist precipitating on the sewer walls after a certain time and draining through the sewer system. It must be taken into account which disinfectant may be discharged into the sewage system and in which quantity.
  • the nozzle can have an additional connection via which compressed air is supplied in a controllable manner, the compressed air supporting the generation of the fog or only enabling it in interaction with the design of the nozzle.
  • the compressed air can, for example, be supplied via a compressor.
  • the supply of compressed air can be regulated via a control unit on a supply hose.
  • the nozzle has a diaphragm with the outlet opening, the width of the outlet opening being variable.
  • the width of the outlet opening can be through a Replacement of the aperture or by means of changing the aperture can be achieved.
  • Means for changing the diaphragm width can, for example, be designed in the same way as in the case of a diaphragm of a camera.
  • the outlet opening of the nozzle can also be changed by exchanging the diaphragm and adapted to the corresponding purpose and to the diameter of a channel opening and a channel.
  • the adapter has sealing means in the region of the second opening. This can be used to seal the adapter, which is filled with disinfectant, and the environment outside the adapter or the device. Such a device is then brought over the channel openings in such a way that the channel openings themselves and a sewer pipe or connection piece are also covered.
  • Sealing means can be produced, for example, by means of a rubber seal, a silicone seal or other sealing elements made of plastic. For example, thermoplastic elastomers (TPE) should be mentioned here.
  • TPE thermoplastic elastomers
  • the seals are attached to the adapter at the lower edge in the region of the second opening and extend circumferentially at the lower edge or the second opening.
  • channels have a siphon in which water is received. From this section a piece of pipe projects upwards, for example, so that the channel opening which is formed by the open part of the pipe is surrounded by water.
  • the adapter for such a channel does not necessarily need separate sealing means, but is immersed in the water that surrounds the sewer pipe. Thus, a barrier and a separation from the environment are established via the siphon or the water.
  • the designs of the adapter thus also provide disinfection of the channel opening and the channel parts which surround or have the channel opening.
  • At least one laterally extending cover device is arranged on the adapter.
  • media-carrying channels there are often channels that lead to channel openings, the channels being open in a room. So that these channels can also be disinfected, at least one cover device can be attached to the adapter, which is laterally connected to the adapter on an outer wall.
