A device and a method for disinfecting pipelines and the use of the device are described, the device having a nozzle, a supply line and a sealing unit. The sealing unit is arranged at a distance behind the nozzle and the feed line is used to supply a medium to the nozzle. The nozzle and the sealing unit are arranged on the supply line and the nozzle atomizes the supplied medium. The sealing unit is inflatable by means of the medium.

Description

A device and a method for disinfecting at least one channel are described.

background

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 the supply and / or removal of substances during the manufacture or processing of products of various types and for the supply and / or removal of products.

Depending on the medium that is routed in the channels, the channels must be cleaned as well as 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.

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 arise during processing lead into the gullies and channels, in which some of the waste generated during processing also ends up.

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. There are legal limit values for the contamination or pollution of sewers with Listeria or other bacteria. In order to comply with these limit values, cleaning, which is normally not able to eliminate the bacteria, is disinfected.

Bacteria and / or virus contamination can also occur in ventilation ducts of buildings or vehicles as well as in ducts for the supply and discharge 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.

However, a complete disinfection of the channel is never achieved because with the spray device the jet 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 among those available Possibilities remains.

To remedy the aforementioned disadvantages is from the DE 20 2020 101 331 a device and a method for disinfecting media-carrying channels are known. 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 the supply of a Disinfectant and an outlet opening through 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.

A disadvantage of this prior art, however, 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, part of the disinfectant will not get into the channel and the other channels connected to this channel and thus the disinfectant effect is reduced and more disinfectant is required for disinfection.

task

There is therefore the task of showing the possibility of disinfecting at least one media-carrying channel and, in particular, other channels of various designs connected to it, whereby the required amount of disinfectant must be kept low and still a complete disinfection can be achieved.

solution

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 supply line serves to supply a medium to the nozzle and the nozzle and the sealing unit are arranged on the supply line. The nozzle atomises the supplied medium and the sealing unit can be inflated by means of the medium.

With the aid of the device, 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, with the entire surface of the media-carrying channels from the introduced disinfectant is misted or wetted, ie comes into contact with the disinfectant.

The channel itself can have further channel openings with e.g. 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. For this purpose, 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. Additionally or alternatively, 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.

Furthermore, the number of devices for disinfecting a pipeline system and the use of a device must be determined in accordance with the diameter and length of the pipeline system and the delivery rate of a device that ensures that the mist with the disinfectant from the nozzle into the pipe of the Pipeline system is introduced.

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 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 sewer or 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 duct openings in the level below . Furthermore, it would then be necessary in such a conventional disinfection, the respective pipe of the Shut off the pipeline system or sewer so that the disinfectant cannot immediately drain off via a sewage system or the like. Here, too, the disinfectant would escape and thus not a complete disinfection of the sewer system, the pipeline or the pipeline system. In order to achieve appropriate disinfection of the pipeline with a conventional disinfectant poured into a pipeline, in addition to shutting off the pipeline to be cleaned, a pressure-tight shut-off or sealing of the pipe system openings in the lower levels must be carried out, which is a great effort leads and therefore cannot be achieved with conventional pipe system openings, especially since no corresponding sealing means are provided or present. These would first have to be introduced into the pipeline and the pipeline system and then removed again.

Here, the device described and the associated disinfection allow the advantage that the device can be simply inserted into the opening of a channel or a pipe and the channel or pipe is sealed via the sealing unit. A disinfectant that is introduced as a mist can thus distribute itself in the entire sewer system or pipeline system without the disinfectant escaping or the disinfectant flowing off quickly, which would reduce the disinfectant effect.

To this end, 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. In a further embodiment, there is also the possibility that different media can be fed to the nozzle via the feed line. An air-disinfectant mixture can also 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 various 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 throwing distance are achieved. The nozzle itself is designed as a mist nozzle.

The disinfectant used is selected according to the type of contamination or load on 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 flowing off via the sewer system. It must be taken into account which disinfectant may be discharged into the sewage system and in what 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 conjunction 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.

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 achieved by exchanging the diaphragm or by means of changing the diaphragm width. Means for changing the diaphragm width can, for example, be designed 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 application and to the diameter of a channel opening and a channel.

In an advantageous embodiment of the invention according to claim 1 it is provided that 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 is then inflatable so that the channel is almost completely covered by the sealing unit is sealed by the sealing unit. In this way, on the one hand, the channel is sealed in the direction of its opening. At the same time, however, 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 atomized with air at a pressure of preferably more than 6 bar.

In an advantageous embodiment of the invention according to claim 3 it is provided that the sealing unit is an inflatable bellows, an inflatable ball or an inflatable cushion and / or that the sealing unit is made of flexible plastic or rubber. The sealing unit can thus be designed as part of the supply line or arranged on the supply line, the supply line running through the sealing unit or opening into it on one side and opening out on the other side.

In an advantageous embodiment of the invention according to claim 4 it is provided that the sealing unit can be inflated via a separate supply line or that the sealing unit can be inflated via the supply line and / or that the medium is air and / or chemicals and / or disinfectants and / or mixed with air. or aerated disinfectant.

In an advantageous embodiment of the invention according to claim 5 it is provided that the feed line is connected to the sealing unit to the nozzle via a valve.

In an advantageous embodiment of the invention according to claim 6 it is provided that the valve is a safety pressure valve.

In an advantageous embodiment of the invention according to claim 7 it is provided that the valve closes the connection between the supply line and the nozzle until a presettable pressure is reached, the connection between the supply line and the sealing unit being opened at the same time when the supply line is acted upon Medium the sealing unit inflates or inflates and seals the channel surrounding the sealing unit and the valve opening the connection to the nozzle when the presettable pressure is reached or exceeded. The sealing unit can thus be inflated via the supply line and the medium and thus the channel can be sealed without the need for a separate supply of the sealing unit, e.g. with compressed air, to inflate the sealing unit.

In a further advantageous embodiment of the invention, the sealing unit is separated from the supply line and supplied with compressed air via a separate line. A valve, which is required in the embodiment according to claim 6, can thus be omitted. The sealing unit can be inflated via this separate line.

In an advantageous embodiment of the invention according to claim 8 it is provided that when the presettable pressure is reached or exceeded, the valve opens the connection to the nozzle and closes the connection between the supply line and the sealing unit. In this way, the nebulization of the disinfectant is started automatically when the sealing unit is subjected to a presettable pressure and inflated.

In an advantageous embodiment of the invention according to claim 9 it is provided that the valve is connected to a control unit that controls a compressor unit that supplies the medium to the supply line and the control unit detects the opening and closing of the valve and when the valve is opened when it is reached or if the presettable pressure is exceeded, disinfectant is supplied from a tank. In this way, the sealing unit is initially only inflated with air and only after the sealing unit has been inflated is disinfectant introduced into the supply line so that it is atomized via the nozzle.

In an advantageous embodiment of the invention according to claim 10 it is provided that the nozzle atomizes the medium with the attached disinfectant in the channel.

In an advantageous embodiment of the invention according to claim 11 it is provided that the valve is a ball valve or a spring-loaded pressure relief valve. In the embodiment as a ball valve, a robust valve is used that fulfills its function regardless of the medium. When using a spring-loaded pressure relief valve, the supply line to the nozzle is released after the preset pressure has been reached, so that the medium is then nebulized directly.

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 that is formed by the open part of the pipe is surrounded by water. This does not pose a problem for the device according to the invention, since it is introduced directly into the pipe.

However, the duct opening and the siphon should also be disinfected separately. It is advisable to do this before the device according to the invention is introduced into the pipe.

In a further embodiment, an adapter is also provided in front of the supply line. The adapter can be designed in the form of a tent or a cover bell. At least one laterally extending cover device is arranged on the adapter. The adapter can be placed over the siphon and seals it off. Another nozzle is then provided, which the The disinfectant is atomized and the siphon can also be disinfected.

The above-mentioned object is also achieved by a method for disinfecting sewer lines using the device described above, and where the device is pushed into the opening of the channel until the sealing unit is completely inserted into the channel and the sealing unit is inflated until the duct is almost completely sealed in the area of the sealing unit and then disinfectant is atomised through the nozzle in the duct.

In an advantageous embodiment of the invention according to claim 12 it is provided that further channels and / or channel sections connected to the channel, which all together form a channel system, are additionally sealed off from the environment with a cover bell. This prevents the atomized disinfectant from escaping through these channels and / or channel sections.

Furthermore, the above-mentioned object is also achieved by using a device according to one of the embodiments described above for disinfecting sewers, gullies, ventilation channels and / or channels for supplying and / or removing substances during the manufacture or processing of products.

For example, the device can be used to disinfect sewers, gullies, ventilation channels and / or channels for the supply and / or removal of substances during the manufacture or processing of products in medical supply stores, for disinfection in food factories, for disinfection in meat processing, for disinfection in the 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 for passenger transport (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 the living area, 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 drain pipe 12th . The drainpipe 12th has an opening 14th on.

About the opening 14th is a channel 16 accessible. The channel 16 can lead to a sewer or other sewage system. The channel 16 functions as a media-carrying channel in the versions shown 16 . The illustrated embodiments of 1-4 relate to devices for disinfection of flow pipes 12th , Channels 16 such as those provided for in meat processing plants, for example.

The gully 10 has a siphon 18th on. The siphon 18th serves as an odor barrier and can, for example, together with a cover bell, prevent bad smells from escaping from the drain pipe 12th impede. The siphon 18th surrounds the drain pipe 12th so that, in interaction with the cover bell (not shown in the figures), bad smells can escape through the opening 14th is prevented. For this purpose, the cover bell is on the upper section of the inlet pipe 12th put on. The cover bell surrounds the upper end of the drain pipe 12th . The cover bell can be attached to a lower base of the siphon 18th rest or be arranged at a slight distance from this, so that in the siphon 18th running water causes the level in the siphon to rise 18th leads, after reaching a certain level the water in the siphon 18th over the opening 14th into the drain pipe 12th (see also the illustration of 4th ).

2 shows a schematic plan view of a gully 10 with a drain pipe 12th in a further embodiment, wherein the drain pipe 12th not down as in the execution of 1 , but is led away to the side. It's a slider too 20th provided that an escape of odors from the drain pipe 12th prevented. Access is therefore only possible via the siphon 18th and the water it contains. The slider 20th can be removed for cleaning and disinfection purposes, so that the channel 16 in the drainpipe 12th is accessible.

3 shows a schematic plan view of a gully 10 with a drain pipe 12th yet another embodiment. In this embodiment extend laterally from the siphon 18th Gutters 22nd , via which wastewater can be carried away. The gutters 22nd extend in the plane of the floor of a room in which, for example, meat is processed. Waste water from this room runs along the floor and gets into the gutters 22nd . From the gutters 22nd the water flows into the siphon 18th and over the siphon 18th into the drain pipe 12th .

There are other types of gullies 10 and sewer pipe assemblies for which the cover bell described below 30th for disinfecting the media-carrying channels 16 can be used.

In the embodiments of the drains shown 10 and the drainage pipes 12th it is not a matter of special designs which as such are essential for the technical teaching described herein or which are particularly different from the prior art, but rather special forms of gullies 10 and drain pipes 12th of the prior art shown for what the cover bell described herein 30th can be used.

4th shows a schematic side view of an arrangement with a gully 10 according to the execution of 1 . The gully is also provided 10 and the drain pipe 12th to be disinfected in the upper area.

At the gully 10 it is a gully 10 which is provided on the ground in a meat processing plant. Therefore get into the gully 10 Wastewater that is contaminated with leftover meat, blood, etc. The gully 10 and the associated drainage pipe 12th therefore offer an ideal breeding ground for bacteria such as Listeria. It is therefore necessary to use the gully 10 and the drain pipe 12th to be cleaned and disinfected at regular intervals, whereby the elimination or reduction of bacteria can only be achieved by disinfection with an appropriate disinfectant. This depends on the material of the drain pipe 12th and to choose appropriate disinfectants for the bacteria that are likely to be encountered.

As the drain pipe 12th a kink 13th at a lower portion, it is not possible to use the drain pipe 12th and in particular the walls of the drain pipe 12th showing the canal 16 surrounded, to be disinfected by means of a disinfectant, which is applied from above through the opening 14th is poured. The disinfectant would because of the kink 13th at least those in the horizontal section of the channel 16 located walls of the drain pipe 12th do not wet it completely, so that there is no disinfection and elimination of bacteria in these areas. 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 drainage pipe 12th cannot be completely disinfected.

The cover bell 30th however, the channel offers a possibility 16 completely disinfect, leaving them on the surfaces of the inner walls of the duct 16 on the drain pipe 12th no bacteria can be detected after an appropriate treatment.

A nozzle is used for this 60 that have a feed line 61 is supplied with disinfectant and / or a mixture of air and disinfectant, into the drainage pipe 12th inserted. The nozzle 60 downstream is an inflatable bellows 62 arranged with the supply line 61 is connected and the supply line 61 passes through. The inflatable bellows 62 so gets into the drainpipe 12th inserted so that it no longer protrudes from this. Then the inflatable bellows 62 via the supply line 61 inflated by a compressor, not shown. This is how the inflatable bellows seals 62 the drain pipe 12th in its surroundings. This prevents subsequent over the nozzle 60 dispensed disinfectant upwards from the drain 12th exit.

In an advantageous embodiment of the invention, the inflatable bellows 62 not with the supply line 61 directly connected, but there is a separate supply line, which is used to connect the inflatable bellows 62 pressurize and inflate this, making this the drain pipe 12th seals.

The inflatable bellows 62 is via the feed line 61 inflated. It can be the inflatable bellows 62 inflated with air alone or with disinfectant or a mixture of disinfectant and air.

Is the inflatable bellows 62 inflated and seals the drain pipe 12th from, is over the supply line 61 to the nozzle 60 Disinfectant and / or a mixture of disinfectant and air under pressure passed and the nozzle 60 nebulises the medium supplied in this way.

Because the inflatable bellows 62 the drain pipe 12th seals, no nebulized medium can escape from the nozzle 60 is misted, from the drain pipe 12th reach. That about the nozzle 60 Nebulized disinfectant will be completely in the drain pipe 12th brought in. Because the nebulization at the nozzle 60 takes place under pressure, the generated fog is also around the kink 13th of the pipe, there up from the drainage pipe 12th nothing can escape.

In the inflatable bellows 62 is a valve 63 arranged. At the valve 32 it is a ball valve, in a special embodiment of the invention it is a safety valve. The use of a spring-loaded pressure relief valve is also being considered.

The valve 63 is used to initially reduce the pressure caused by the medium to be introduced via the supply line 61 is supplied to use to the inflatable bellows 62 inflate and thus the drainpipe 12th to seal. Via the valve 63 can be the pressure with which the inflatable bellows 62 inflated, can be preset. After in the inflatable bellows 62 the preselected internal pressure is present, which means that the drain pipe is almost completely sealed 12th guaranteed, the valve switches 63 access to the nozzle 60 free and it becomes the medium that is on the supply line 61 is supplied, correspondingly via the nozzle 60 fogged.

If a spring-loaded safety valve is used, the supply line is automatically opened when the preselected pressure is reached 61 to the nozzle 60 opened so that immediately after reaching the presettable pressure with which the inflatable bellows 62 is to be inflated, an atomization of the medium via the nozzle 60 he follows.

In 4th is also the cover bell 30th provided, which has an adapter 50 and a distributor element 32 having. The distribution element 32 is about a hose 34 connected to a compressor. Compressed air is supplied via the compressor. Via a controller 36 on the hose 34 the amount of compressed air can be regulated.

The air pressure can also be regulated. Via the distribution element 32 For example, a pressure of up to 8 bar can be managed.

Via a hose 38 a disinfectant is added to the distributor element 32 fed. It can be through the hose 38 different disinfectants can be supplied. There is a hose for this 38 Made of a suitable material so that the hose will not be damaged 38 or degradation of the hose 38 comes. The hose 38 consists of a suitable plastic for this purpose. Also the distribution element 32 consists of a suitable material that is not subject to damage or decomposition by an introduced disinfectant. Preferably there is the distributor element 32 made of stainless steel or a chemical-resistant plastic.

The disinfectant is contained in a container. The container stands over the hose 38 with the distributor element 32 in connection. Depending on the position of the regulator 36 the disinfectant in the distributor element is released via the compressed air introduced 32 mixed and then through a valve (not in 4th shown) controlled in the supply line 61 brought in.

Via the distribution element 32 can therefore in the supply line 61 only compressed air or a mixture of air and disinfectant are introduced.

In a special embodiment is in the distributor element 32 a mist nozzle is arranged, which allows disinfectant or an air-disinfectant mixture to escape

The distribution element 32 is in a further advantageous embodiment of the invention via an intermediate piece 40 connected to an adapter 50. The adapter 50 is preferably cylindrical, with the intermediate piece in an upper, first end 40 is received in a first opening. The lower second end of the adapter 50 is with a second opening designed to be open, so that the wall of the adapter 50 on a bottom surface of the gully 10 in the area of the siphon 18th can be placed without the adapter 50 or the intermediate piece 40 in contact with the top of the drain pipe 12th come. The adapter 50 can therefore also be designed essentially as a tube which has an intermediate piece 40 in the area of the first opening of the adapter 50 with the distributor element 32 connected is.

About the distribution element 32 it is also possible to nebulize disinfectant in the space that the adapter 50 spans, so that the part of the gully and the channel 16 that doesn't have the nozzle 60 disinfected with nebulised disinfectant.

The selection of the throughput and the amount of disinfectant for disinfection of a corresponding sewer length, with normal diameters of sewer pipes or drainage pipes 12th in the range of 100-200 mm, as for the embodiment of the device, allows complete disinfection within a few minutes.

A few minutes after the end of the nebulization, the mist has settled, so that the device can be removed and there is no risk of aggressive disinfectants escaping.

A method of disinfecting the canal 16 for the above-described designs of drainage pipes 12th includes the device that is in the canal 16 in its opening 14th is pushed in until the inflatable bellows 62 completely in the canal 16 is introduced. Then the inflatable bellows 62 inflated until the canal 16 in the area of the inflatable bellows 62 is almost completely sealed. Then, in the manner described above, disinfectant is applied through the nozzle 60 in the canal 16 fogged.

To further with the channel 16 connected further channels and / or channel sections, which all together form a channel system, can also be disinfected with a cover bell 30th a seal against the environment can be made.

The method and the device thus offer a simple, inexpensive and quick disinfection of media-carrying channels 16 Compared to devices and methods known from the prior art, complete disinfection can be achieved while reducing the amount of disinfectant to be used. Various disinfectants can be used as disinfectants, with no restrictions imposed by the devices.

The method and devices described here advantageously enable the use of highly effective, aggressive disinfectants, because these are introduced in small quantities by the mist, so that there is no risk of pollution of the environment with disinfectants or high pollution of the wastewater with disinfectants, which into the sewer system got.
