Furthermore, the device has a cleaning unit which is at least partially insertable into the pipe to be cleaned. In this case, this cleaning unit has at least one first loading device, which are suitable and intended to act on an inner wall of the pipe to be cleaned with a flowable cleaning agent (ie in particular a liquid and / or gaseous cleaning agent).

According to the invention, the device has a manufacturing and / or storage device for the cleaning agent and the device further comprises a movement device which is suitable and intended to move the cleaning unit relative to the tube in its extension direction and / or longitudinal direction.

It is therefore proposed according to the invention a device which has an insertable into the tube cleaning unit, which acts on the inner wall of this with the cleaning agent for cleaning the tube. Advantageously, the production and / or storage device is at least temporarily in fluid communication with the said loading device. It is possible, as described in more detail below, that the production device generates a specific cleaning agent itself, for example, produces dry ice with the aid of CO ₂ pellets. However, it would also be possible that the device has only a storage device for storing the cleaning agent.

The manufacturing and / or storage device can have several components. It would thus be possible for the production and / or storage device to have only one receiving device, such as a reservoir for the cleaning agent, for example, and this is then conveyed to the loading device, for example by means of pumps. In addition, the production and / or storage unit may also comprise components which also serve for the production of the cleaning agent, in particular in the case of dry ice.

In addition, the device could have a mixing unit which is suitable and intended to generate the cleaning agent by a mixing process. In particular, mixing ratios of the cleaning agent could be adapted to the specific task.

Advantageously, the device has at least one and optionally a plurality of transport lines, which transport the cleaning agent from the production and / or storage unit to the individual loading devices. This transport line can be designed as a flexible hose.

Furthermore, the device may have a conveying device which conveys the cleaning agent in the direction of the at least one loading device. Thus, for example, one or more pumps and / or one or more compressors may be provided, which promote the cleaning agent to the loading devices.

In a further advantageous embodiment, the holding device is suitable and intended to hold pipe sections or pipe sections to be cleaned a pipe and / or wear. In this case, the holding device may have a total of a carrier which can be parked, for example on a base, such as a floor, such as a ship's floor. By this procedure, it would be possible to clean the pipes to be cleaned, for example during transport by means of ships.

In a further advantageous embodiment, the holding device is arranged in a housing. It is possible that this housing is closable or can be shut off from the environment. In this way it can be prevented that detergent during the cleaning process comes to the outside and causes, for example, impurities. It would also be conceivable under these conditions that sterilizing agents are used as cleaning agents, which could also have a harmful effect on people.

In a further advantageous embodiment, the flowable medium is a gaseous medium and / or a liquid medium. In addition, it would be possible for a plurality of cleaning and / or treatment media to be used, for example water and / or a solvent for pre-cleaning, a cleaning agent for the purpose of a main cleaning and, for example, water for rinsing and / or, for example, air for drying.

In a further advantageous embodiment, the device has at least one cleaning and / or filter unit for cleaning and / or filtering the cleaning agent. Thus, for example, a cleaning and / or filtering unit may be provided which is suitable and intended for cleaning and / or filtering of cleaning agents to be recycled. In this way, cleaning agent can in turn be cleaned or filtered after use and be accessible as a result, for example, a detergent circuit.

Advantageously, the pipes to be cleaned are circular pipes. In this way, an internal cleaning of the tube (in particular by rotation of the cleaning unit and / or the tube itself) is facilitated, for example, by the cleaning unit is rotated with respect to the pipe to be cleaned.

In a further advantageous embodiment, the holding device rotatably supports the pipe to be cleaned. Advantageously, the tubes are rectilinear tubes. In a further advantageous embodiment, the pipe to be cleaned is preferably between 4 and 25 m, and particularly preferably between 4 and 20 m, between 2 and 30 m.

In a further advantageous embodiment, the holding device supports the tube slightly obliquely with respect to a horizontal direction. For example, the tube could be inclined at an angle to a horizontal plane that is between 1 ° and 20 °, preferably between 1 ° and 10 °. In this way it is achieved that a flowable and in particular liquid medium, with which an inner wall of the tube has been charged, can again flow out of the tube by itself or under the action of gravity.

In a further advantageous embodiment, the cleaning unit has at least two cleaning segments, which are telescopic with respect to each other, in particular in a longitudinal direction of the tube, movable. In this way, the loading means can be introduced by extending the telescopic tube in the pipe to be cleaned.

In a further advantageous embodiment, the device has a - in particular flexible - conduit means for conveying the cleaning agent, which extends at least temporarily within the cleaning unit and is suitable and intended to convey the cleaning agent to the loading device.

In a further advantageous embodiment, only one of these cleaning segments on a loading device. However, it would also be possible for a plurality of cleaning segments and / or all cleaning segments to have such loading devices. It is possible that these loading devices are arranged along a longitudinal direction of the cleaning unit. However, it would also be possible for a plurality of loading devices to be arranged on individual cleaning segments or also on several or all cleaning segments, even in a circumferential direction of the respective cleaning segments. By thus configured embodiment is not only possible to retract the cleaning unit in the pipe to be cleaned, it is then also possible that the inner wall of the pipe to be cleaned is cleaned by means of the loading devices.

In a further advantageous embodiment, the movement device has a pneumatic and / or hydraulic drive device. It is possible that the telescopic extension of the cleaning unit or of the individual cleaning segments takes place under the effect of air pressure and / or liquid. In this case, for example, a compressor may be provided, which possibly also serves to generate a cleaning agent, for example for the production of gaseous dry ice. This compressor can act at least indirectly, the cleaning unit or the telescopic tube of the cleaning unit to introduce it into the pipe to be cleaned.

In a further advantageous embodiment, the device has a rotating device in order to rotate the pipe to be cleaned with respect to the cleaning device esp. With respect to a longitudinal direction of the tube. It is possible that the cleaning device itself is rotated within the pipe to be cleaned. However, it would also be possible that the cleaning unit is arranged rotationally fixed, but the tube rotates with respect to the cleaning unit. For this purpose, the Holding device, for example, have rotatable rollers on which the pipe to be cleaned is supported or held. If these rotatable rollers rotate, the tube to be cleaned will rotate accordingly. In addition, however, it would also be possible for the rotary drive of the pipe to be cleaned to take place, for example, via disk-like or wheel-like elements which in particular contact an outer wall of the pipe to be cleaned.

It is possible that the rotating device allows a complete rotation of a tube through 360 °, but it would also be conceivable that the rotation of the tube is not complete, but for example, only certain angles of rotation allowed, for example, a rotation of + or -180 °.

Advantageously, the rotating device has at least one element which contacts an outer surface of the pipe to be cleaned, such as, for example, the rolls or rolls mentioned above.

It is also possible that a lateral distance of such roles, which serve to rotatable bearings of the pipe to be cleaned, can be changed in terms of their distance. In this way, the holding device can also be adapted to different pipe diameters.

In a further advantageous embodiment, the device has a return device for returning the cleaning agent from the tube. Thus, for example, the cleaning unit having a return channel, which is also introduced into the pipe to be cleaned and which serves to receive detergent, but possibly also of dissolved dirt. About this return line, the cleaning agent and / or can also be contaminants from the tube after their removal from the inner wall finally removed. In this case, this feedback device can also open into the said filter devices, which permanently detach detached dirt from the cleaning agent.

In a further advantageous embodiment, the device has at least one second loading device for acting on an outer surface of the pipe to be cleaned. In this way, not only an internal but also an external cleaning of the respective tube can be made. It is possible that this second loading device is arranged stationary with respect to the holding device. It is also possible, for example, for a multiplicity of such second application devices to be arranged one behind the other in a longitudinal direction of the tube. In addition, however, it would also be possible for one or more loading devices to be provided, which are movable in a longitudinal direction of the pipe to be cleaned so as to clean it along its entire longitudinal direction.

In addition, a circumferential cleaning of the tube can be achieved by the above-described rotation of the tube. In addition, however, it would also be possible for a plurality of loading devices to be distributed in the circumferential direction around the pipe to be cleaned. In this case, it would be possible, for example, for the device to have a carrier on which a multiplicity of holding devices is arranged, which allow full loading of the outer wall of the tube to be cleaned. This carrier with this plurality of loading devices could be movable in the longitudinal direction of the pipe to be cleaned.

Furthermore, these second application devices could also be in flow connection with the preparation and / or storage unit for the cleaning agent. In this case, it would also be possible for several such production or treatment facilities for the cleaning agent to be available. So it is possible to apply the pipe to be cleaned with different media on its inner and outer walls to clean it. It would also be possible for the individual cleaning media to be applied in succession to the inner surface. In addition, the device may also have tempering, which serve for tempering, for example for heating the cleaning media. In this way, the temperature of the cleaning agent can be controlled and / or regulated.

In a further advantageous embodiment, the device also has a conveying device in order to guide the cleaning agent to the outer wall of the pipe to be cleaned. For example, pump devices can be provided which transport the cleaning agent to the outer wall of the pipe to be cleaned.

In a further advantageous embodiment, the cleaning device has a second manufacturing and / or storage device for the cleaning agent and the cleaning device and / or the pipe to be cleaned is preferably at least partially between the first manufacturing and cleaning device and the second manufacturing and / or storage device arranged. This embodiment is particularly suitable for longer pipes that can not be cleaned only from one side. In this embodiment, the invention proposes a two-sided production and supply of the Detergent before. Advantageously, the cleaning device is located in the longitudinal direction between the first and the second manufacturing and storage device.

In a further advantageous embodiment, the device has a compressed air generating device, which acts on a first cleaning medium with compressed air, so as to produce the cleaning agent from this first cleaning medium. In this embodiment, the first cleaning medium is in particular dry ice, which may be present in the form of CO ₂ pellets particularly preferably. This cleaning medium is acted upon by a flowable medium, preferably by means of compressed air, so as to produce the actual cleaning agent in the form of dry ice.

In this case, a transport device may be provided to guide the cleaning medium into the mixing chamber. Thus, for example, a transport screw can be provided which conveys the cleaning medium, which is present in particular in the form of pellets, into the mixing space. The compressed air can also be supplied to this mixing chamber and so the cleaning agent can be generated, which is then applied via the cleaning nozzles on the surface to be cleaned.

Advantageously, the compressed air generating device is arranged so that the compressed air can be introduced into the mixing chamber. A compressed air jet preferably has such a high pressure that the dry ice pellets in the mixing chamber are preferably moved in the direction of the compressed air jet and, in particular, accelerated.

In a further advantageous embodiment, the application device has a nozzle with which the compressed air jet, after having preferably passed through the mixing chamber and has been enriched with dry ice pellets, is directed onto the object to be cleaned or the surface to be cleaned. Due to the impact of the dry ice pellets on contaminants of the surface to be cleaned, the contaminants are suddenly cooled and cracked. The resulting cracks in the contaminants can penetrate further dry ice pellets. Due to the ambient temperature and the ambient pressure, the dry ice pellets sublimate when hitting the object to be cleaned. The carbon dioxide in the sublimation increases its volume many times and thus dissolves the dirt from the surface.

The compressed air generating device may in particular be a compressor. Advantageously, the compressor is used both as a compressed air generating device and for acting on the nozzles of the cleaning device. Preferably, this is the same compressor.

In a further advantageous embodiment, the device has a second loading device in order to apply a further medium to the (inner) surface of the tube.

In a further advantageous embodiment, the transport device for transporting the cleaning medium has a drive unit approximately in the form of an electric motor. there This conveyor is preferably designed such that it can promote the preferably present as piece goods cleaning medium and piecemeal from the reservoir to the mixing chamber.

In a further advantageous embodiment, the device has a further cleaning unit, which cleans the surface to be cleaned by a mechanical contact. These may be, for example, lamella or brush-type cleaning devices. Preferably, this further cleaning device is a lamella cleaning device which removes dirt residues in particular by mechanical contact. Advantageously, a corresponding slat structure of this slat cleaning device is rotatably arranged. Preferably, this further cleaning unit is arranged to be movable relative to the pipe to be cleaned, in particular movable in a longitudinal direction of the pipe and / or rotationally movable with respect to the longitudinal direction of this pipe.

In a further advantageous embodiment, the device has a second reservoir for storing compressed air. In this case, for example, a buffer memory may be provided, which in turn is supplied by a compressor with compressed air. In this way, a constant pressure can be achieved.

In a further advantageous embodiment, the cleaning unit has a fastening means for fastening at least one traction cable of a fastening device. In this case, this fastening means may preferably be placed such that the cleaning unit can be pulled through the pipe to be cleaned.

In a further advantageous embodiment, at least one of said movements, that is, either the movement of the entire cleaning unit and / or the movement of the loading device relative to the pipe to be cleaned, clocked. Advantageously, the movement of the cleaning unit is clocked with respect to the surface to be cleaned. In this way, a very quick cleaning of the surface to be cleaned (the pipe) is possible.

In a further advantageous embodiment, the device has at least one tempering device for tempering at least one flowable medium. For example, the compressed air used to produce the detergent can be tempered. In this way it is possible, even with very different outside temperatures always to achieve a constant temperature of the compressed air and thus a qualitatively constant generation of the detergent. Also, the detergent itself can be tempered.

In a further advantageous embodiment, the device has a feed device to supply the medium to the reservoir. Thus, for example, a filler neck can be provided, via which the cleaning medium, in particular in the vertical direction, is supplied to the reservoir. In this case, this feeder can be thermally insulated, for example via a closing mechanism that allows after filling of pellets to complete the reservoir.

The present invention is further directed to a method for cleaning pipes, wherein the pipe to be cleaned by means of a holding device is held in a predetermined position and inserted into the pipe to be cleaned, a cleaning unit, said cleaning unit having a loading device which the pipe and in particular an inner wall of the tube is supplied with a flowable cleaning agent, wherein the cleaning agent is transported from a manufacturing and / or storage device to the loading device.

In a preferred method, the pipe to be cleaned is at least temporarily rotated during its cleaning and rotated in particular with respect to its longitudinal direction. In a further advantageous embodiment, the loading device is introduced by means of a pneumatic or hydraulic drive in the pipe to be cleaned. In another method, an outer surface of the pipe to be cleaned is acted upon by means of second admission means with a flowable medium.

In a further advantageous method, dry ice is used as the cleaning agent.
