Description

Device and method for disinfecting media-carrying channels and use of the device

description

A device and a method for disinfecting media-carrying channels and the use of the device are described.

background

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.

Depending on the medium that is routed in the channels, 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.

For example, in meat or meat products processing companies, the type and quantity of the processed meat (e.g. beef, pork, poultry, etc.) and the prevailing climatic conditions (temperature, humidity, etc.) Take influence on the distances between the disinfection, drains and sewers are disinfected, which are located in the rooms in which the meat or meat products are processed and stored. In addition to water, liquids and impurities (e.g. blood, leftover meat, etc.) that occur during processing get into the gullies and channels.

The gullies and channels thus offer an ideal basis for bacteria such as Listeria. There are legal limits for the contamination or pollution of sewers with Listeria or other bacteria. In order to comply with these limit values, 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.

State of the art

Disinfection is usually carried out by pouring in a disinfectant or by injecting one Disinfectant into a channel using a spray device.

However, complete disinfection of the channel is never achieved because the spray device can only hit part of the channel wall and a disinfectant flows along the channel wall when it is poured. Since channels usually always have a "kink" or a branch or deflection, the known disinfection measures are inevitably restricted.

To release a channel disinfected according to the state of the art, it is sufficient to fall below a limit value. For this purpose, a check is carried out at an accessible point on the duct wall.

The disadvantages resulting from the prior art are obvious here. On the one hand, the entire canal wall is never disinfected and, on the other hand, the disinfection has to be carried out more frequently due to the further contamination present.

Another disadvantage, particularly when pouring a disinfectant, is that a large amount of disinfectant is required. This in turn flows into the sewer system, resulting in increased clarification or cleaning costs in a downstream sewage treatment plant or a corresponding plant.

The disadvantage described above can sometimes also lead to the fact that special, highly effective disinfectants may not be used, since the required amount would lead to excessive pollution of the wastewater, whereby sufficient disinfection cannot be achieved and the Disinfection remains below the available options.

task

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.

solution

The above-mentioned object is achieved by 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.

With the aid of the device, 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.

Put on also means that 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. For this purpose, cover bells can be used, which seal the channel openings. Additionally or alternatively, 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.

For this purpose, 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. Furthermore, with such a conventional disinfection 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. Here, too, the disinfectant would escape and thus not complete disinfection. In order to be able to achieve appropriate disinfection, in addition to shutting off the floor duct to be cleaned, a pressure-tight shut-off or sealing of the duct openings in the lower level is required, which is a high effort and cannot be achieved with conventional duct openings. because no corresponding fasteners are provided there.

Here, 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.

For this purpose, 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. In further embodiments, 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. For example, 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.

To generate a fog, 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.

In a further embodiment, 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. In further embodiments, not only can the nozzle itself be exchanged, but 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.

In a further embodiment, 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. 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.

In further embodiments, 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.

In a further embodiment, at least one laterally extending cover device is arranged on the adapter. In 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. For this purpose, the adapter can have an opening which can be opened or closed as required in order to attach at least one cover device. The cover device is attached to the channel or the floor, wall or ceiling section in such a way that the channel is completely spanned by the cover device, the cover device sealingly resting against the corresponding floor, wall and / or ceiling section.

In a further embodiment, the cover device is designed like a tunnel. The covering device thus spans the at least one channel. The covering device can preferably have a flexible or deformable, dense material which is held and shaped by a support structure. The support structure can be formed by stirrups or the like which are arranged at regular or irregular intervals and which are connected to one another via the dense material (for example a film). Furthermore, the brackets or the like can be designed in such a way that they have a standing surface for attachment to a floor, wall and / or ceiling section. The formation of the cover enables the

To compress or stretch cover device so that channels can be covered in a relatively large area with a cover device of a defined length, because the cover device is adapted to a certain extent to the length of the channel by stretching or tensioning the material of the cover device and lengthened or by Pushing together the bracket or the like can be shortened. Thus, the cover device can also have wall sections at opposite connection points which can be removed or opened in order, for example, to connect a cover device on one side to a device and on the other side to a further device or a further cover device. A further cover device can, for example, also be designed as a branch, so that several cover devices and / or adapters of devices can be connected to one another via this branch.

For this purpose, in a further embodiment, the cover device can be arranged removably on the adapter.

In a further embodiment, the covering device has support areas which have sealing means. In this way, the space spanned by the cover device is sealed off from the environment so that the disinfectant contained in the channel and the cover device does not get into the environment or the environment of the device and the cover device. Sealing means of the support areas can consist of the same substances as the sealing means on the second opening of an adapter. Furthermore, such sealing means can be provided in the area of the connection points between cover devices and adapters so that no disinfectant emerges from the arrangement. The above-mentioned object is also achieved by a method for disinfecting media-carrying channels, a device according to one of the embodiments described above being applied to a channel opening in such a way that the adapter completely covers the channel opening and seals off the space surrounding the adapter from the environment , and then a disinfectant is introduced via the nozzle into the space surrounding the adapter as a mist.

The method thus offers the possibilities and advantages which have already been achieved above for the device and the associated disinfection of media-carrying channels.

In a further embodiment, channel sections connected to the media-carrying channel and / or further channel openings are sealed off from the environment with a cover device according to one of the embodiments described above and / or a cover bell. In this regard, too, reference is made to the features and advantages already mentioned above. Cover bells can be provided with a siphon, i.e. a liquid reservoir that surrounds a channel opening, in particular in the case of channel openings, the cover bell being simply placed on the channel opening and the lower edge of the cover bell then being received in the water so that a seal is achieved.

Furthermore, the above-mentioned object is also achieved through the use of a device according to one of the embodiments described above for disinfecting sewers, gullies, ventilation channels and / or channels dissolved for the supply and / or removal of substances in the manufacture or processing of products.

For example, the device can be used for disinfecting gullies and sewage pipes in medical supply stores, for disinfection in food processing plants, for disinfection in meat processing, for disinfection in baked goods production, for disinfection in beverage production, for disinfection in agriculture, in particular with regard to the required hygiene in animal husbandry, dust binding for potato and onion processing, and for disinfection to maintain warehouse hygiene and for pest control. Furthermore, the device can be used for disinfection in the transport sector, including vehicles which are used to transport people (cars, buses, trains, ships, aircraft). Vehicles usually have a ventilation or air conditioning system with a duct system for supplying and removing treated air. Bacteria or pollutants can also accumulate in these channels, which make regular disinfection necessary. The device can be used advantageously here. Furthermore, the device can also be used for disinfection in industry or in residential areas, for example to disinfect ventilation ducts of air conditioning systems or other ventilation systems. In industry, it is also necessary to disinfect channels for the supply and / or removal of substances during the manufacture or processing of a wide variety of products at regular intervals.

Detailed description of exemplary embodiments

1 shows a schematic plan view of a gully 10 with a drain pipe in one embodiment. In the exemplary embodiment shown, the drain pipe is a waste water pipe 12. The waste water pipe 12 has an opening 14. A channel 16 is accessible via the opening 14. The channel 16 can open into a sewer or other sewage system. In the embodiments shown, the channel 16 functions as a media-carrying channel 16. The exemplary embodiments shown in FIGS. 1-8 relate to devices 30 for disinfecting sewer pipes 12, channels 16 and gullies 10, as are provided, for example, in meat processing plants.

The gully 10 has a siphon 18. The siphon 18 serves as an odor barrier and can, for example, together with a cover bell, prevent bad smells from escaping from the sewer pipe 12. The siphon 18 surrounds the waste water pipe 12, so that in interaction with a cover bell (not shown in the figures) the outlet of bad smells through the opening 14 is prevented.

For this purpose, the cover bell is placed on the upper section of the sewage pipe 12. The cover bell surrounds the upper end of the waste water pipe 12. The cover bell can rest on a lower bottom of the siphon 18 or be arranged at a slight distance therefrom, so that water flowing into the siphon 18 leads to an increase in the level in the siphon 18, after which one At a certain level, the water in the siphon 18 passes through the opening 14 into the sewer pipe 12 (see also the illustration of FIG. 4).

FIG. 2 shows a schematic plan view of a gully 10 with a sewer pipe 12 in a further embodiment, the sewer pipe 12 not being led downwards, as in the embodiment of FIG. 1, but away to the side. A slide 20 is also provided which prevents odors from escaping from the sewer pipe 12. Access is therefore only possible via the siphon 18 and the water it contains. The slide 20 can be removed for cleaning and disinfection purposes, so that the channel 16 in the sewer pipe 12 is accessible.

Fig. 3 shows a schematic plan view of a gully 10 with a sewer pipe 12 of yet another embodiment. In this embodiment, channels 22 extend laterally from the siphon 18, via which waste water can be carried away. The channels 22 extend in the plane of the floor of a room in which, for example, meat is processed. Waste water from this space runs along the floor and reaches the channels 22. The water flows from the channels 22 into the siphon 18 and via the siphon 18 into the waste water pipe 12.

There are other designs of gullies 10 and sewer pipe arrangements for which the following described devices 30 for disinfecting the media-carrying channels 16 can be used.

The embodiments of the gullies 10 and the sewer pipes 12 shown are not special designs which as such are essential for the technical teaching described herein or which are particularly different from the prior art, but are special forms of gullies 10 and sewer pipes 12 of the prior art, for which the devices 30 described herein can be used.

FIG. 4 shows a schematic side view of an arrangement with a gully 10 according to the embodiment of FIG. 1 and a device 30 for disinfecting the gully 10 and the waste water pipe 12.

The gully 10 is a gully 10 which is provided on the ground in a meat processing plant. Therefore, wastewater that is contaminated with meat residues, blood, etc. get into the gully 10. The gully 10 and the associated sewer pipe 12 therefore offer an ideal breeding ground for bacteria such as Listeria. It is therefore necessary to clean and disinfect the gully 10 and the sewer pipe 12 at regular intervals, the elimination or reduction of bacteria can only be achieved by disinfection with an appropriate disinfectant. For this purpose, appropriate disinfectants are to be selected depending on the material of the sewage pipe 12 and the bacteria that are likely to be encountered.

Since the sewer pipe 12 has a kink 13 at a lower portion, it is not possible to use the sewer pipe 12 and in particular to disinfect the walls of the sewer pipe 12, which surround the channel 16, by means of a disinfectant which is poured from above through the opening 14. Because of the kink 13, the disinfectant would not completely wet at least the walls of the sewage pipe 12 located in the horizontal section of the channel 16, so that no disinfection and the elimination of bacteria can occur at these points. Injecting a disinfectant via a corresponding spray device with a spray jet also leads to the same result, so that the inner walls of the sewer pipe 12 cannot be completely disinfected.

However, the device 30 offers a possibility of completely disinfecting the channel 16, so that no bacteria can be detected on the surfaces of the inner walls of the channel 16 on the sewer pipe 12 after a corresponding treatment.

The device 30 has an adapter 50 and a nozzle 32. The nozzle 32 is connected to a compressor via a hose 34. Compressed air is supplied via the compressor. The amount of compressed air can be regulated via a regulator 36 on the hose 34.

The air pressure can also be regulated. In the exemplary embodiments shown, an air pressure of 1.5-6 bar can be achieved via the nozzle 32.

A disinfectant is fed to the nozzle 32 via a hose 38. Various disinfectants can be supplied via the hose 38. For this purpose, the hose 38 is made of a suitable material so that there is no damage to the hose 38 or decomposition of the Hose 38 is coming. For this purpose, the hose 38 consists of a suitable plastic. The nozzle 32 is also made of a suitable material which is not subject to damage or decomposition by an introduced disinfectant. The nozzle 32 is preferably made of stainless steel or a chemically resistant plastic.

The disinfectant is contained in a container. The container is connected to the nozzle 32 via the hose 38. Depending on the position of the regulator 36, the disinfectant is introduced from the nozzle 32 into the adapter 50 via the compressed air introduced.

The nozzle 32 is designed as a mist nozzle and has a chamber in its nozzle body 325 in which the disinfectant and the compressed air introduced are mixed in such a way that a mist emerges from the aperture 323 (outlet opening) of a diaphragm 322 (see FIG. 8) Opening 323 exits.

The width and the configuration of the opening 323 are decisive for the direction and configuration of the applied mist, consisting of compressed air and disinfectant droplets.

The nozzle 32 itself is connected to the adapter 50 via an intermediate piece 40. In the exemplary embodiment of FIG. 4, the adapter 50 is of cylindrical design, the intermediate piece 40 being received in a first opening in an upper, first end. The lower, second end of the adapter 50 is designed to be open with a second opening so that the wall of the adapter 50 can be placed on a floor surface of the gully 10 in the area of the siphon 18 without the adapter 50 or the intermediate piece 40 in contact with the upper one The end of the sewer pipe 12 come. The adapter 50 can therefore can also be designed essentially as a tube which is connected to the nozzle 32 via an intermediate piece 40 in the region of the first opening of the adapter 50. For this purpose, the intermediate piece 40 also has an opening. The nozzle 32 can be connected to the intermediate piece 40 via a screw connection, for example.

It is also possible to connect the nozzle 32 to the intermediate piece 40 via a union nut 321 (see Fig. 8), the union nut 321 being unscrewed and then the nozzle 32 with its nozzle body 325 guided through an opening in the intermediate piece 40. The union nut 321 is then screwed onto a threaded section 326 of the nozzle body 325, a connection being established between the intermediate piece 40 and the nozzle 32. A sealing ring 324 can also prevent gas from escaping. Furthermore, additional seals can be provided which, for example, surround the opening in the intermediate piece 40 in a ring shape and seal it off with respect to the nozzle 32.

The adapter 50 consists of a plastic, in particular a chemical-resistant plastic, so that no damage occurs even from aggressive disinfectants, or a metal such as stainless steel. The connection between the nozzle 32, the intermediate piece 40 and the adapter 50 is made airtight, so that no mist introduced into the interior of the adapter 50 from the arrangement can get into the environment.

The disinfectant is atomized by the design of the nozzle 32 and with the aid of the compressed air and emerges as a mist from an opening 323 of a diaphragm 322 of the nozzle 32. The nozzle 32 is aligned in such a way that the opening 323 protrudes into the space spanned by the adapter 50. The fog with the disinfectant was able to get into the room and into the channel 16 formed by the sewer pipe 12. The mist is evenly distributed in the room spanned by the adapter 50 and in the sewer pipe 12. Depending on the throughput, which for example up to 101 / h at a pressure of 3 bar, for example, can be disinfected with 1.5 to 3 liters of disinfectant 150-250 m ³ room volume. It is thus possible, depending on the diameter of the channel 16, to completely disinfect channels 16 up to a length of 25-50 m, the entire surface of the inner walls of the sewer pipes 12 being wetted with the disinfectant.

Advantageously, via the adapter 50, which protrudes laterally from the sewage pipe 12 in the area of the opening 14, the exposed outer area of the sewage pipe 12 is also disinfected.

The walls of the gully 12 can be disinfected by direct contact with a disinfectant, since they are freely accessible. Disinfectants can also be added to the water in the siphon 18. In the exemplary embodiment shown, the water in the siphon 18 also serves as a barrier to prevent the disinfectant from escaping, which is bound in the water and can therefore no longer enter the environment as a mist.

In further embodiments, not shown, the adapter 50 can also be designed in such a way that it spans the walls 11 of the gully 10, the diameter of the adapter 50 being greater than the diameter of the gully 12. In addition, at the lower edge in the area of the first opening of the adapter 50 sealant can be attached so that the adapter 50 is placed on the surface of a floor in a sealing manner can. This prevents mist from escaping from the adapter 50 in the area of the contact surface on the floor when the device 30 is in operation. Therefore, not only the gully 10 and the channel 16 are advantageously completely disinfected, but also an area of the floor around the gully 10.

FIG. 5 shows a perspective illustration of an arrangement with a gully 10 according to the embodiment of FIG. 2 and a further embodiment of a device 30 for disinfecting the gully 10 and the waste water pipe 12.

The embodiment of the device 30 shown in FIGS. 5 and 6 differs from the embodiment of the device 30 shown in FIG. 4 in that the adapter 50 is not cylindrical or tubular, but essentially has the shape of a pyramid. At the upper end in the area of the first opening, the pyramid-shaped adapter 50 has an interface for connecting the nozzle 32. For example, a horizontal cover surface which has an opening can be provided at the upper end of the pyramid-shaped adapter 50. A section of the nozzle body 325 can be inserted into this opening, which section is firmly connected to the top surface of the adapter 50 via the union nut 321 by screwing.

The pyramid-shaped adapter 50 is placed over the gully 10 and surrounds not only the gully 10, but also an area of the floor in which the gully 10 is arranged. The sewer pipe 12 is arranged in the floor of the room and is therefore not directly accessible via the floor. To disinfect the channel 16 and the gully 10, the slide 20 is removed in the illustrated embodiment of the gully 10, so that an area of the channel 16 is accessible via a free cross-sectional area of the sewer pipe 12.

A mist containing a disinfectant is then introduced into the adapter 50 via the nozzle 32. The disinfectant passes through the mist not only into the gully 10 and the surrounding area of the floor, but also into the channel 16, so that the channel 16 is completely wetted with disinfectant through the mist and bacteria are eliminated.

So that from the adapter 50 no fog and no

Disinfectants can get into the environment, the adapter 50 has sealing means on its lower bearing surfaces which achieve a seal. For example, sealing means can consist of rubber or a rubber-like material or a thermoplastic elastomer (TPE), silicone or other suitable materials. When selecting the materials for the sealants, care must be taken that the sealants are not decomposed or damaged by the disinfectant.

The selection of the throughput and the amount of disinfectant for disinfecting a corresponding sewer length, with usual diameters of sewer pipes 12 in the range of 100-200 mm, as for the embodiment of the device 30 of FIG. 4, allows complete disinfection within a few minutes.

After a few minutes the mist has settled, so that the device 30 can be removed and there is no risk of aggressive disinfectants escaping. FIG. 6 shows a plan view of the arrangement of FIG. 5. In this embodiment, the base area of the adapter 50 is adapted to the base area of the gully 10. However, this does not necessarily have to be the case.

FIG. 7 shows a perspective illustration of an arrangement with a gully 10 according to the embodiment of FIG. 3 and yet another embodiment of a device 30 for disinfecting the gully 10 and the waste water pipe 12.

The embodiment of the device 30 of FIG. 7 differs from the embodiment of the device 30 of FIGS. 5 and 6 in that cover devices 52 are attached to the side of the adapter 50. the

Covering devices 52 can be permanently connected or releasably connectable to corresponding sides of the adapter 50.

In a releasable connection of the cover device 52, the corresponding points on the sides of the adapter 50 have means for closing openings for the cover device 52. An adapter 50 can have a plurality of such openings or only a single such opening. A plurality of openings can be provided on one side of an adapter 50, next to one another or in different positions. The connection can be made, for example, via magnetic elements and additional sealing elements, so that in a closed state of the opening without a cover device 52, no mist can escape when the device 30 is in operation.

The means for covering these openings can be completely removed from the adapter 50 or can remain on the adapter 50 when it is opened. The connection points of the cover devices 52 can have corresponding fastening elements so that, for example, a magnetic connection or the like between a Cover device 52 and the corresponding wall of the adapter 50 can be produced. In addition, a cover device 52 can also have a seal at the contact point, which seal rests against a corresponding wall of the adapter 50 or interacts with a further seal of the adapter 50.

The cover devices 52 have, for example, a material web 56 made of plastic, which is given a tunnel-like shape by means of brackets 54. The material web 56 consists of a gas-impermeable material, so that no mist can be given off through the material web 56 into the environment. Sealing means can be provided on the lower region of the material web 56, which in the attached state provide a seal between the base and the material web 56, so that no mist can escape from this either.

For the sealants used, reference is made to the examples described above.

The tunnel-like cover devices 52 can be connected to an adapter 50 at one end.

The cover devices 52 preferably span the channels 22 in such a way that an edge region of the channels 22 and the adjacent floor can also be disinfected. For this purpose, openings in the adapter 50 can extend from the bottom, the support edge of the adapter 50 being or can be interrupted by the opening. This ensures that the channels 22 can be disinfected over their entire length.

FIG. 8 shows a schematic representation of a nozzle 32 of the devices 30 of the embodiments of FIGS. 4-7. The nozzle 32 has a nozzle body 325, which in turn has a lateral connection 327 for the hose 34 for the supply of compressed air. The compressed air and the disinfectant are mixed in the nozzle body 325 and output as a mist via the aperture 322. For this purpose, the diaphragm 322 has an opening 323.

A metering nozzle 328 can be screwed into a further section of the nozzle body 325 via a corresponding threaded section 329. The dosing nozzle 328 has a connection 330 for the hose 38 and the disinfectant. That Disinfectant comes into the nozzle body 325 via the connection 330 and depending on the position of the dosing nozzle 328 and is atomized with the aid of the compressed air that is supplied via the connection 327 and output as a mist, for example as a moist mist. The orifice 322 is held on the nozzle body 325 via a union nut 321 and a corresponding threaded section 326. In addition, a sealing ring 324 is provided, which prevents compressed air or disinfectant from escaping. The sealing ring 324 can consist of the aforementioned materials for the sealing means or have such.

As already set out for the above-described embodiments, the connection of the nozzle 32 to cover surfaces, the intermediate piece 40 and the like can take place in that the nozzle body 325 is inserted into a corresponding opening. The diameter of these openings is so large that the threaded section 326 protrudes through but the nozzle body 325 cannot slip through. The union nut 321 can then be screwed on, whereby on the one hand the sealing ring 324 and the screen 322 are fastened to the nozzle body 325 and the nozzle body 325 is firmly fastened to the top surface, the intermediate piece 40 or the like.

A method for disinfecting the channels 16 for the above-described designs of gullies 10 and sewer pipes 12 includes placing an adapter 50 on a gully 10, the space spanned by the adapter 50 being sealed off from the environment. A mist containing disinfectant is then introduced into the adapter 50 and thus into the channels 16 via the nozzle 32, the mist completely filling the channels 16 so that at least the entire inner surface of the channels 16 is disinfected. The method and the device 30 thus offer a simple, inexpensive and rapid disinfection of media-carrying channels 16 and gullies 10, with complete disinfection being able to be achieved compared with devices and methods known from the prior art. as

Disinfectants, various disinfectants can be used, with no restrictions imposed by the devices 30. Advantageously, the method described here and the devices 30 enable the use of highly effective, aggressive disinfectants, because these are introduced by the mist in small amounts, so that there is no risk of pollution of the environment with disinfectants or a high pollution of the wastewater with disinfectants which is in the Sewerage.
