DESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

It is therefore an object of the invention to provide an arrangement and a method for removing paint mist when painting a component, such as aircraft fuselage, in which the surface structure of the applied paint on the component is improved and in which the burden on the employees is reduced.

To solve this problem, the arrangement according to the invention and the method according to the invention is proposed.

According to the invention is in an arrangement for removing paint mist when painting a component, such as an aircraft fuselage comprising an air supply device and an exhaust device, wherein the supply air device is disposed in a lower region or a lower environment of the component and wherein the exhaust device in an upper region or a arranged upstream of the component, proposed that the supply air device is designed to supply relative to the ambient air of the component heated, a thermal flow along a surface of the component forming supply air, and that the exhaust device for discharging with the thermal flow along a surface of the component flowing , the paint mist entraining exhaust air is formed.

The inventive arrangement of the supply air device and the exhaust device, a targeted flow around a component to be painted, preferably with very low air velocity, a. In this case, the supply air device for supplying heated relative to the ambient air of the component, a thermal flow along a surface of the component forming supply air is formed. Thus, the flow around the component is generated by a thermal buoyancy flow below and along the surface of the component to be painted. The fact that the supply air has a low excess temperature compared to the surrounding room air, a vertically upward Konventionsströmung forms, which applies to the contour of the fuselage and the paint mist, also called overspray, which arises during the painting process, picks up and dissipates , Therefore, the surface structure of the paint applied to the component is improved. Advantageously, harmful solvent vapors are removed by the exhaust air flowing along the surface of the component. The burden on employees is therefore reduced.

In a preferred embodiment of the arrangement it is provided that the exhaust air device is formed by generating a negative pressure relative to the ambient air for discharging the exhaust air.

In contrast to the removal of exhaust air by an air flow, which is generated by an overpressure, it is advantageous to bring about discharge of the exhaust air by a negative pressure relative to the ambient air, as thus excessive turbulence in the exhaust air and in the ambient air surrounding the exhaust air are avoided , A particularly turbulence-free, substantially laminar flow pattern of the exhaust air is thereby achieved, so that a particularly efficient removal of the overspray or of the paint particles consisting of small particles takes place.

In a further preferred embodiment of the arrangement it is provided that the exhaust air device is designed as a particular elongated swirl hood, wherein the swirl hood is preferably arranged above the component, wherein the swirl hood is particularly preferably arranged aligned along a longitudinal axis of the component such that the axis of rotation of a in and / or circulating flow generated by the swirl hood extends substantially parallel to the longitudinal axis of the component, and wherein very particularly preferably the swirl hood is designed as a double-sided swirl hood.

With particular advantage, the arrangement of a swirl hood designed, preferably centrally and / or arranged above the component exhaust air prevents that possibly form with paint mist and / or paint mist enriched return flows into the ambient air. In the advantageous embodiment, the swirl hood detects the thermal current with the recorded color particles and leads them out of the room, in particular the paint shop. In this case, a circulation flow forms in the swirl hood, which stabilizes the thermal flow to be dissipated and thus prevents a backflow of the exhaust air enriched with paint mist. Particularly advantageous is a double-sided configured or double-acting swirl hood, as a particularly efficient and acting in several directions spatial exhaust air is ensured. Furthermore, it is advantageous that the swirl hood is formed as an elongated swirl hood and arranged aligned along a longitudinal axis of the component. If, for example, the component is embodied as an aircraft fuselage, aligning an elongated swirl hood along the longitudinal axis of the aircraft fuselage in a particularly advantageous manner results in a large amount of paint mist arising during painting, preferably in the Essentially completely, so that along the entire length of the component improved surface texture of the paint and improved protection of the employees is achieved.

A further expedient embodiment of the arrangement is characterized in that the supply air device is designed as an air distribution channel, that the air distribution channel Luftverteilmittel, in particular Luftausströmöffnungen or Luftausströmkanäle, and that the Luftverteilkanal is preferably arranged below the component, particularly preferably in or under a floor covering of a Lackierraums, and that the supply air device is very particularly preferably arranged aligned substantially along a longitudinal axis of the component.

Below the component to be painted, in particular below the aircraft fuselage, there is at least one air distribution channel arranged parallel to the longitudinal axis of the component or the fuselage, via which air is advantageously introduced into the painting space at a very low air velocity. In order to achieve uniform outflow over the channel length, corresponding air distribution means, such as air outflow openings or air outflow channels, are located within the air distribution channels.

An embodiment of the supply air device as an air distribution channel offers the advantage of being able to arrange the supply air device in a suitable manner, for example in a paint shop. Particularly in the case of elongated components, the design as an air distribution channel is advantageous, since the air distribution channel can run along a longitudinal axis of the component, so that supply air can be supplied over the entire length of the component. For this purpose, in particular at regular or irregular intervals Luftverteilmittel, in particular Luftausströmöffnungen or Luftausströmkanäle, provided on Luftverteilkanal. By suitable arrangement of the air distribution, the Zuluftzuführung can be optimized for painting component. The air distribution channel is preferably arranged below the component in order to favor an advantageous thermal flow which sweeps vertically upwards along the surface of the component to be painted. A particularly preferred embodiment provides that the air distribution channel is arranged in or under a floor covering of a painting room. By arranging the Luftverteilkanals in or under a floor covering of a Lackierraumes the design of the floor covering is made possible as a flat floor covering, so that components in the painting can be easily moved without being hindered by arranged above the floor covering Luftausströmkanäle in the movement. Furthermore, it is through in the floor or under the floor covering of the painting, So in particular in the floor covering or in the bottom of the painting, integrated Luftverteilkanäle possible to provide increased safety for employees, as the recessed in the ground Luftverteilkanäle no obstacles in the movement paths of employees represent. In particular, the Luftverteilkanäle are no so-called "trip hazards".

In a particularly preferred embodiment of the arrangement it is provided that at least one room supply device is provided, which is arranged in particular at a predetermined horizontal distance from the component, wherein the room supply device is designed for the lateral supply of room supply air in the environment of the component.

In a particularly advantageous manner, supply, in particular by lateral supply, of room supply air into the environment of the component ensures that room air entrained with the thermal flow is replaced. In particular, no negative pressure in the environment of the component or in the ambient air of the component can be formed in an advantageous manner, so that also back flows of the exhaust air are prevented in the ambient air. Such backflows could occur in that a negative pressure forms in the ambient air or the environment of the component to be painted due to the discharged exhaust air or discharged thermal flows, which is compensated by backflow of the thermal flow. By supplying room air to the environment of the component such backflows are prevented. The proportion of room air mixed by induction of the thermal flow can also be tracked, for example, via layer air passages into the painting room.

Furthermore, the supply, in particular the lateral supply of room supply worried further laminarization or calming along the surface of the component stroking thermal flow or exhaust air, the room air flows in the direction of the component to be painted, and at least partially enveloping the thermal flow and ascending with the thermal flow flows in the direction of exhaust air device. By enveloping the exhaust air flow or the thermal flow, the thermal flow is spatially limited and a laminar thermal flow is favored. Due to the spatial limitation of the thermal flow is also limited spatially dissipated paint mist or overspray, so that an even more effective arrangement for removing paint mist when painting a component is provided, which also also for a special protection of employees provides. The room supply device can be arranged at a suitable horizontal distance from the component. The horizontal distance is to be determined according to the situation, how strongly the thermal flow is formed, how strong the backflow is to be prevented, and how far the thermal flow is spatially limited.

According to a further preferred embodiment of the arrangement, it is provided that the arrangement comprises a filter system for filtering the exhaust air.

Advantageously, appropriate filter systems clean the exhaust air from the paint particles before the extracted air, or the exhaust air or extracted thermal flow, to the outside, that is blown into the environment.

The filtering of the exhaust air through a filter system expediently causes further protection of both the staff and the environment, as harmful paint particles and / or solvent vapors are removed from the exhaust air or the exhaust air to be discharged into the environment.

Furthermore, it can be expedient to provide a filter system for filtering the supply air. The cleaning of the supply air through a filter system advantageously causes no dust particles to be contained in the paint mist dissipating thermal flow, which can settle on the surface to be painted and there can lead to a deterioration of the surface structure.

A particularly preferred embodiment of the arrangement provides that the arrangement comprises a Zuluftheizvorrichtung for heating the supply air, and / or that the arrangement comprises a compressor and / or a dehumidifier for compressing and / or dehumidifying the supply air.

A preferred arrangement of a Zuluftheizvorrichtung allows the supply air to heat, so that forms a particularly advantageous thermal flow along and over the surface of the component to be painted.

Furthermore, the arrangement of a compressor or a dehumidifier may be provided in the supply air flow. By compacting and / or dehumidifying the supply air, a particularly trouble-free painting of the component is possible, in particular, an improved surface structure of the paint applied to the component is established. In particular, the dehumidification of the air prevents moisture from precipitating on the paint and affecting the surface structure of the paint.

Another solution to the problem underlying the invention is provided by the provision of a painting space for painting a component, such as an aircraft fuselage, wherein the painting space is a previously described arrangement for discharging paint mist during painting of a component, such as an aircraft fuselage.

Further, the problem underlying the invention by a method for removing paint mist when painting a component, such as an aircraft fuselage, feasible with a prescribed arrangement or a prescribed paint shop, wherein arranged in a lower region or in a lower environment of the component supply air device Supply air is supplied, being discharged with an arranged in an upper region or in an upper environment of the component exhaust air exhaust air, it being provided that the supply air is heated relative to the ambient air of the component, that along a surface of the component in Direction of the exhaust device extending thermal flow forms, and that with the thermal flow along a surface of the component flowing, the paint mist entraining exhaust air is discharged from the exhaust device.

In the method according to the invention, a targeted flow around a component to be painted, for example, of an aircraft fuselage, preferably with a very low air velocity, is advantageously effected by supplying fresh air by means of the supply air device and discharging the exhaust air by means of the exhaust air device. Due to the flow around the surface or through the thermal flow flowing along the surface, a paint mist arising during painting is preferably removed in a targeted manner and removed from the exhaust air device, so that no unwanted contamination of the surfaces to be painted occur and, moreover, the burden on the employees is reduced. It is of particular advantage that the supply air is heated relative to the ambient air of the component, so that forms a thermal flow.

In a preferred embodiment of the method, this is characterized in that the exhaust air is removed by means of an exhaust air device, which is arranged as a particularly elongated, preferably above the component, particularly preferably aligned along a longitudinal axis of the component, very particularly preferably double-sided swirl hood.

By discharging the exhaust air by means of a particular elongated, preferably double-sided swirl hood, it is particularly efficiently prevented that paint mist or so-called overspray enriched with paint mist can flow back into the ambient air surrounding the component. As a result, it is particularly advantageously prevented that the paint process in his technical process is disturbed that paint mist settle in the vicinity of the component and that employees are affected by inhalation of the paint mist health.

In a further preferred embodiment of the method is provided that the supply air is supplied impulse poor.

By low-pulse supply of supply air is advantageously prevented that form strong turbulence in the supply air and adjacent to the supply air or to the thermal flow ambient air.

According to a further preferred embodiment of the method, the temperature of the supply air is at most 30 Kelvin, preferably at most 20 Kelvin, more preferably at most 10 Kelvin above the temperature of the room air.

The resulting air velocity at the fuselage results from the temperature difference between the supply air and the surrounding room air. By limiting the maximum temperature difference to 30 Kelvin, preferably to 20 Kelvin, more preferably from 10 Kelvin above the temperature of the ambient air can thus be adjusted in a suitable manner, the speed of the thermal flow, depending on the used paints and environmental conditions, in particular depending on the specific Lacquers and / or dependent on the painting particle sizes of the paint particles transported in the paint mist, a higher or a lower temperature difference and thus a higher or lower speed of the thermal flow can be selected.

A further preferred embodiment of the method provides that in a predetermined horizontal distance, preferably laterally of the component, room supply air is supplied, which essentially replaces the room air mixed with the thermal flow by induction.

Thus, the proportion of room air admixed to the thermal jet by induction, preferably via layered air outlets, is advantageously tracked into the hall or into the painting room. Furthermore, the supply of room air expediently prevents backflows from forming due to underpressures arising in the ambient air of the component, whereby a more efficient discharge and increased protection of the employees against the paint particles of the paint mist is achieved. Advantageously, the supply of room air leads to a spatial delimitation of the thermal flow, in particular to a localization of the thermal flow in the immediate vicinity of the surface of the component to be painted instead. It thus reduces, inter alia, the energy demand, because only a smaller amount of supply air to form the thermal flow is needed. Furthermore, the safety is increased since particle mist can not enter into the ambient air of the component to be painted and thus the risk to employees is reduced.

Another and particularly preferred embodiment of the method is characterized in that the exhaust air and / or the supply air is purified by a filter system.

The cleaning of the supply air through a filter system advantageously causes no dust particles to be contained in the paint mist dissipating thermal flow, which can settle on the surface to be painted and there can lead to a deterioration of the surface structure. Advantageously, by cleaning the exhaust air through a filter system, the burden on the environment is reduced because harmful paint mist or solvent vapors can not get into the environment.

In a particularly preferred embodiment of the method, it is provided that the supply air is supplied by means of an air distribution means, in particular air outflow openings or air outflow ducts, designed as an air distribution channel.

It can be provided in an advantageous manner for a low-pulse outflow of warm air that is provided as air distribution means a pipe section of a Luftverteilkanals with a Rohrabschnittachsenparallelen Ausströmschlitz, a tube or hose section with a plurality of distributed on the circumference Luftausströmöffnungen or a hose section with air-permeable surface.

The hose or pipe section can, for example, have an air-permeable synthetic fiber surface, a pulp surface or another surface material suitable for low-pulse air passage. Instead of a Ausströmschlitzes also a plurality of individual Luftausströmöffnungen (nozzles) or Luftausströmkanäle, which are arranged in a channel part can be used.

In a further solution to the problem underlying the invention, a painting method for painting a component is provided, which comprises a method for removing paint mist when painting a component according to the method described above.

• Fig. 3 in a perspective view of another arrangement for removing paint mist when painting an aircraft fuselage.

Preferred embodiments of the invention

Fig. 1 shows a perspective view of an arrangement 100 for removing paint mist during painting of a component 10. The component 10 is formed as a fuselage 11. The aircraft fuselage 11 is located vertically above a floor 12 of a painting room 13. An incoming air device 14 is integrated or arranged in the floor 12 or below the surface of the floor covering 15 of the painting room 13. The supply air device 14, which is designed to supply with respect to the ambient air of the component 10 heated supply air, is also designed as air distribution channel 16. By heated air outlets 17 of the air distribution channels 16 heated supply air 18 flows from below in a vertical upward direction in the direction of the component 10 and the aircraft fuselage 11. The relative to the ambient air of the fuselage 11 heated supply air 18 has a temperature difference of a maximum of 30 Kelvin compared to the ambient air.

Along the surface 19 of the component 10, an ascending thermal flow 20 is formed, which discharges lacquer mist, so-called overspray, arising in the coating process in the vertical direction upward in the direction of an exhaust air device 21. The exhaust device 21 is in Fig. 1 formed as a bilateral swirl hood 22. The exhaust air or the thermal flow 20, which carries away the paint mist, enters from below into the swirl hood 22 and is guided sideways in the direction of circular segment-shaped curved end portions 23 of the swirl hood. In the circular segment-shaped end portions 23 of the swirl hood 22, circulation flows 24 are formed, whereby a sideways leakage of the exhaust air is prevented in ambient air. The circular flow 24 formed in the circular segment-shaped end portions 23 of the swirl hood 22, which contains the entrained by the thermal flow 20 particles mist is removed via exhaust ducts 25 from the swirl hood 22 and forwarded to a not shown here filter system for cleaning the exhaust air. For this purpose, a negative pressure is generated within the exhaust ducts 25.

At a horizontal distance AH from the surface 19 of the fuselage 11 there is a room supply device 26 through which room supply air 27 is supplied, which essentially replaces the room air admixed with the thermal flow by induction. The room air 27 flows substantially impulsively to the thermal flow 20 and in particular limits the spatial extent of the thermal flow 20 to the vicinity of the surface 19 of the fuselage 11th

In the Fig. 2 the arrangement 100 is the FIG. 1 shown in a side view. The formed as aircraft fuselage 11 component 10 is located above a bottom 12 of a Lackierraumes integrated into the ground 12, or below the floor covering 15 is a Luftverteilkanal 16 a Zuluftvorrichtung 14 is arranged. The supply air device 14 has air distribution means designed as air outlet openings 17 or air outlet channels. From the Luftausströmöffnungen 17 heated supply air 18 flows impulsively in a vertical upward direction in the direction of the fuselage 11 from. Along the surface 19 of the fuselage 11, this results in the formation of an ascending thermal flow 20, which penetrates into a swirl hood 22 arranged above the aircraft fuselage 11. The swirl hood 22 has circular segment-shaped end regions 23. Furthermore, exhaust air ducts 25 are provided on the swirl hood, which dissipates the entrained with particle mist exhaust air in the direction of a filter device, not shown. Again Fig. 2 can be seen, the Luftverteilkanäle and the elongated swirl hood 22 along a longitudinal axis LA of the component 10 and the aircraft fuselage 11, aligned. The alignment of the elongated swirl hood 22 along the longitudinal axis LA of the component 10 ensures that substantially all or at least a majority of the surface 19 of the component 10 is surrounded by the thermal flow 20 and a substantial or the entire portion of the thermal flow 20, which carries a paint mist, is dissipated.

Also in Fig. 2 A room supply device 26 is shown, which is supplied with room supply air 27 by means of a room supply air supply channel 28. Room supply air 27 enters room air outlet openings 29, in particular low impulse, into the environment of component 10.

In Fig. 3 an alternative arrangement 100 for removing paint mist when painting a component 10 is shown. In the alternative embodiment, a supply air device 14 comprising two air distribution channels 16 is arranged underneath the component 10 designed as aircraft fuselage 11. Unlike the one in the figures FIGS. 1 and 2 are shown in FIGS FIG. 3 illustrated arrangement 100, the air distribution channels 16 above the floor covering 15 of a floor 12 of a Lackierraumes 13 arranged. Paint is applied to the surface 19 of the fuselage 11 by means of a painting device 30. A thermal flow 20 flows around the surface 19 of the aircraft fuselage 11 and leads during the painting process resulting paint mist with in the vertical direction from above. In a ceiling 31 of the painting room 13 32 circular segment-shaped swirl hoods 22 are arranged in the corner regions. The exhaust air flows along the ceiling 31 of the painting space 13 in the direction of the circular segment-shaped swirl hoods 22 and forms a circulation flow 24 within the swirl hoods 22. Finally, exhaust air ducts 25 carry the exhaust air which surrounds the paint mist in the direction of a filter device (not shown here).
