Definitions

  • a device and a method for disinfecting at least one channel are described.
  • a channel in the context of this invention is a pipe, a channel, several pipes or channels or pipelines or pipeline systems or channel systems in which a medium is guided.
  • a medium can be conducted in liquid or gaseous form or in liquid form with organic and / or inorganic elements in the channel.
  • Such channels can be, for example, sewers, ventilation channels or 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.
  • the channels must be cleaned and disinfected at regular intervals. 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 waste generated during processing also sometimes finds its way.
  • the gullies and channels and the pipes, pipelines and / or further channels connected to the gullies and / or channels thus offer an ideal basis for bacteria, such as, for example, Listeria.
  • bacteria such as, for example, Listeria.
  • Bacteria and / or virus 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 types. State of the art
  • Disinfection usually takes place by pouring a disinfectant or by injecting a disinfectant into a channel with the aid of a spray device.
  • the disadvantage described above can sometimes also mean that special, highly effective disinfectants may not be used, since the required amount would lead to excessive pollution of the wastewater, in which case sufficient disinfection cannot be achieved and disinfection among those available Opportunities remain.
  • a device and a method for disinfecting media-carrying channels are known from DE 202020 101 331.
  • the device described there has a nozzle and an adapter.
  • the adapter surrounds a space and has a first and a second opening and is connected to the nozzle via the first opening.
  • the nozzle has at least one connection for supplying a disinfectant and an outlet opening via which the disinfectant supplied can be introduced into the space spanned by the adapter.
  • the adapter is placed on a channel opening in a sealing manner via the second opening. This disinfects the channel opening and the channel with disinfectant.
  • the disadvantage of this prior art is that the disinfectant sprayed by the nozzle has to penetrate into the channel and the pipeline to which the channel is connected in order to disinfect them as well. Since the channel usually has a kink or branch after its access, the disinfectant from the nozzle must fill the space spanned by the adapter and also penetrate into the pipe of the channel and flow through it. In addition, the disinfectant must overcome the kink following the pipe. Therefore, some of the disinfectant is not in the channel and those connected to this channel, reach further channels and thus the disinfection effect is reduced and more disinfectant is required for disinfection.
  • the above-mentioned object is achieved by a device for disinfecting at least one channel.
  • the device according to the invention has at least one nozzle, a supply line and a sealing unit.
  • the sealing unit is arranged at a distance behind the nozzle.
  • the feed line serves to feed a medium to the nozzle and the nozzle and the sealing unit are arranged on the feed line.
  • the nozzle atomizes the supplied medium and the sealing unit can be inflated by means of the medium.
  • a channel, several connected channels, pipelines or media-carrying channels with gullies of various designs with connection to a pipe system for discharging the media introduced into the channels with gully can be completely disinfected, the entire surface of the media-carrying channels being disinfected by the Disinfectant is misted or wetted, ie comes into contact with the disinfectant.
  • the channel itself can have further channel openings with, for example, further gullies, which then have to be sealed when the disinfectant is introduced, preferably in the form of a mist, whereby in further embodiments the mist can be introduced as a moist or dry mist.
  • cover bells can be used, which seal the duct openings, or further sealing units can be introduced into the pipes or ducts to close them.
  • further devices according to the invention can also be introduced into the channels or pipelines of a pipeline system.
  • the number of devices to be used for the complete disinfection of a pipeline system or sewer system depends on the amount of disinfectant to be introduced via the nozzle and the length of the pipeline system or sewer system and the design of the pipeline system or sewer system. For example, in the case of a very branched pipeline system, it may be necessary to insert several devices into corresponding pipes of the pipeline system in order to achieve complete disinfection of the pipeline system.
  • 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 disinfected or the channel system has the advantage that disinfection can take place over several levels.
  • Conventional disinfection with a disinfectant that is poured or introduced into a channel or a pipe of a pipeline system does not allow disinfection over, for example, several levels because, for example, the disinfectant introduced into an upper level would escape through pipeline system openings or channel openings in the level below .
  • the device described and the associated disinfection allow the advantage that the device can be easily inserted into the opening of a channel or a pipeline and the channel or pipeline is sealed via the sealing unit.
  • a disinfectant which is introduced as a mist, can thus be distributed in the entire sewer system or pipeline system without the disinfectant escaping or the disinfectant flowing off quickly, which would reduce the disinfectant effect.
  • the disinfectant can be introduced as a mist via the nozzle, for example in a pressure range of about 1 bar to 10 bar, a pressure range of more than 6 bar having been found to be particularly advantageous for the device and method according to the invention.
  • the disinfectant is fed to the nozzle via the feed line for supplying a disinfectant.
  • a disinfectant there is also the possibility that different media can be fed to the nozzle via the feed line. It can also be an aerial
  • Disinfectant mixture can be fed to the nozzle in this way.
  • a feed unit is provided, by means of which a medium or a mixture of media can be fed to the nozzle via the feed line.
  • the pressure of the feed can be specified and / or changed via the feed unit.
  • the nozzle is designed so that different disinfectants can be introduced, the disinfectant neither attacking nor damaging the nozzle, the supply line or the sealing unit.
  • 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 compressed air is fed into a further supply line to the nozzle or is contained as a separate supply line in the supply line for the media or media.
  • 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 device can be pushed into an opening of the channel in such a way that in the pushed-in state the sealing unit is completely surrounded by the channel and the sealing unit can then be inflated so that the channel is almost completely covered by the sealing unit is sealed by the sealing unit.
  • the channel is sealed in the direction of its opening.
  • the nozzle is held in the channel and remains positioned there and can only move slightly in the channel during the process of nebulizing the disinfectant, the disinfectant being mixed with air at a pressure of preferably more than 6 bar.
  • the sealing unit is an inflatable bellows, an inflatable ball or an inflatable cushion and / or that the sealing unit consists of flexible plastic or rubber.
