    Apparatus and method for separating particles from an air stream
    The invention relates to a device for separating particles, in particular paint particles, from an air stream, comprising a plurality of deposition layers each having a plurality of deposition elements.
    Moreover, the invention relates to a use of such a device.
    Furthermore, the invention relates to a method for separating particles, in particular paint particles, from an air stream, wherein the particles are deposited on a plurality of deposition elements of multiple deposition layers.
    In several fields of technology, air or an air stream is contaminated with undesirable and / or toxic particles, such as when painting vehicles.
    In such a painting process of vehicles or vehicle components, it is usually not possible to deposit all paint particles on the parts to be painted. Therefore, the air is always contaminated even after a completed painting with potentially toxic paint particles, which is referred to as "overspray". Before supplying this air to the ambient air, the paint particles must be removed from the same.
    Devices for removing or separating paint particles from air or an air stream are known from the prior art. These can work, for example, with chemical filter elements, which can be complicated and expensive. Next is also a way known to deposit paint particles with release agents such as water and / or stone dust from air, which is relatively cumbersome and labor intensive. In addition, filtering devices are known, for example, which comprise a plurality of U-shaped elements for separating paint particles from the air. In this case, a flow velocity of the air is changed so that the paint particles are filtered from the air and collect in the U-shaped elements. However, such a device has the disadvantage that the deposited in the U-shaped elements paint particles are removable from there only with great effort.
    The object of the invention is to provide a device of the type mentioned, which allows a simple and efficient separation of particles from an air stream.
    Another object is to provide a use of such a device.
    It is also an object to provide a method of the type mentioned, with which particles are easily and efficiently separated from a stream of air.
    The object is achieved in that in a device of the type mentioned, the deposition elements are formed as self-contained and spaced-apart bands, wherein the bands of two deposition layers are arranged offset from one another to redirect the air flow between the deposition layers.
    An advantage achieved by the invention is to be seen in particular in that the formation of the deposition elements or deposition layers of the air flow is deflected so that a deposition of the particles, which are usually heavier than the remaining air flow on the tapes is possible. For this purpose, in particular the bands of two adjacent deposition layers can be arranged offset from one another. According to the invention, any number of deposition layers can be arranged, but it is favorable if at least two are provided, which are arranged in particular offset from one another. Furthermore, these can be arranged in layers one behind the other. The bands are preferably arranged parallel to one another and at a distance from one another, wherein a spacing formed between two bands may preferably be less wide than the bands themselves. In order to allow particles to be deposited as uniformly as possible on all bands, it may be favorable if they are of identical construction are formed. The distances between the bands further specify a flow direction of the air flow and also influence its speed. By a device according to the invention is a purely mechanical deposition of
    Particles from an air stream possible, in particular without the use of chemical additives.
    It is preferably provided that each deposition layer comprises at least one mounting for the bands, the bands being arranged at least partially around the mounting. The bands are spaced from each other on the at least one storage arranged or the storage is at least partially disposed within the bands. The bands may for example be at least partially elastic and rest on the storage.
    It is advantageous if each deposition layer comprises two bearings which are of cylindrical design. The deposits of a deposition layer can be arranged along an axis and spaced from each other, wherein the bands are spanned around them. A distance between two bearings is so large that the air flow can flow as freely as possible from the same by distances between the bands. Preferably, the bearings are further formed so that the strips arranged thereon have two sides aligned approximately parallel to one another, wherein particles can be deposited on one of them and the other of these is opposite. The cylindrical bearings are also preferably rod-shaped and can be arranged at an upper and lower end of the device. As a result, the belts are guided in a continuous circulation vertically or from bottom to top. However, it can also be provided that the bands are guided horizontally or from one side of the device to another side, for which purpose the bearings can each be arranged on one side of the device. In addition, any other arrangement of the deposits or the deposition layers with the bands is possible, for example, the bands of the deposition layers can alternately extend horizontally and vertically. In addition, it may be favorable if the bearings are designed such that the bands are displaceable along the bearings of a deposition layer. Thereby, a distance between bands of a deposition layer is variable. The individual bands may preferably be of identical design. But it can also be provided that any number of bands are formed differently from each other, for example, have a different width.
    The device for depositing particles may further comprise a frame construction for receiving the bearings. The bearings are in a simple way and releasably attachable to the frame structure, for example, suspended. As a result, a number of deposition layers can be varied without much effort and a distance between the individual deposition layers can be changed.
    It can be provided with advantage at least one drive to enable the bearings in rotational movement. The bearings preferably carry out a uniform rotational movement, as a result of which the bands also move. The bands are thus designed as conveyor belts. If two bearings are provided per deposition layer, it may be advantageous for a bearing to be driven directly by the drive for the purpose of a rotational movement, which is transmitted by friction to the belts and from there also by friction to the second bearing. As a result, each band is rotatably mounted, whereby each an entire band for the deposition of particles is usable. The drive can be designed so that this constant or only if necessary, set the bearings or the belts in motion. It can also be advantageous if one drive is provided per deposition layer, as a result of which each deposition layer or the strips arranged thereon can be set in motion independently of any other deposition layer. This can prove to be favorable in particular with an arrangement of a multiplicity of deposition layers, since with progress of the deposition layers fewer and fewer particles are present in the air stream, as a result of which fewer and fewer particles are deposited.
    Conveniently, at the end of an outlet region, a suction device can be provided, which accelerates the air flow in their direction. The suction device can be designed, for example, as a fan and can generate or accelerate the air flow even more. The outlet region is preferably arranged after the deposition layers or at one end of the device.
    Further, it is advantageous if an input region is provided, via which the air stream meets a first deposition layer. The entrance area is arranged in particular opposite the outlet area and preferably comprises an entire width of the deposition sites. The air flow arrives over the entrance area to a first deposition layer, which comprises a plurality of bands spaced apart from one another. It can be provided that the air flow in the entrance area z. B. has a speed of 8 m / s and by the distances between the bands on z. B. 70 m / s, preferably to a speed at least twice as high, in particular to a speed 5 times faster, is accelerated. Such an acceleration of the air flow is possible because a flow region of the air is tapered abruptly or almost without transition. Due to the rejuvenation, particles are already deposited on the first deposition layer, since they are usually heavier and thus more sluggish than the remaining air fractions.
    It is also advantageous if a device for removing the particles from the belts is provided. This device can be arranged on the bottom side of the device, for example. It is advantageous if neither water nor release agent or stone meal are needed to separate the particles. The paint removed with the device for removal or the particles are subsequently pulverisable or reusable for the production of inferior paints. With this device, a removal of the particles during operation is possible.
    A use of a device according to the invention is advantageously carried out during the deposition of paint particles from a discharged in a Fahrzeuglackiervorgang airflow.
    The procedural goal is achieved if, in a method of the aforementioned type, the air flow is accelerated through a distance between the deposition elements formed as self-contained bands by the deposition layers, wherein a flow direction through the deposition layers, in particular by offset thereof, is changed.
    It is advantageous if the air flow is accelerated in particular by a first deposition layer or over distances of the strips arranged there and the particles, which are usually heavier than the remaining portions of the air or the air flow, thus on the Abscheidungslagen or the Tapes are deposited. Due to the arrangement of the bands, on the one hand, a speed and, on the other hand, a flow direction of the air flow are changed abruptly or almost without transition, so that heavy particles such B. paint particles do not follow the rest of the air flow or their flow direction can not change fast enough. As a result, these particles are deposited on the belts and thus filtered out of the air stream.
    For this purpose, it can preferably be provided that the air flow is sucked in by a suction device arranged at the end. The suction device may for example be designed as a fan and the air flow can be sucked or generated by distances between the bands of this.
    It is useful if the bands are rotated by a drive, in particular indirectly, in rotation. For this purpose, preferably bearings can be provided which are at least partially enclosed by the bands. Preferably, the bearings can be driven by the drive to perform a rotational movement, whereby the bands are indirectly offset by the friction in motion and move like conveyor belts. The bands of a deposition layer can be stored in particular on two bearings, which are arranged at a distance from each other. The bearings may be cylindrical or rod-shaped and mounted or mounted, for example, on a frame structure of the device.
    It can preferably be provided that the air flow is guided via an input area to a first deposition position. The entrance area can be made so large that it extends over an entire width of the deposition layers. A speed of the air flow is accelerated at the transition from the input area to the first deposition layer or at intervals between the bands mounted thereon, for example from 8 m / s to 70 m / s.
    Preferably, it can further be provided that particles are removed with a device for removal from the belts. It is thereby possible to clean a region of the strips on which no particles are being deposited, from particles already deposited there. This cleaning of the deposition elements during operation is possible.
    Advantageously, moreover, it can be provided that the air flow is sucked through distances between the belts, wherein the particles are deposited on the belts of the deposition layers. Preferably, the bands of two deposition layers are each arranged offset to one another, so that a flow direction of the air stream is changed after each deposition layer. As a result, particles are deposited on each band and at the end of the deposition layers the air flow is at least approximately free of particles. If, after flowing through all deposition layers, impurities or particles are still present in the air stream, they can be filtered, for example, with an additional filter element.
    Further features, advantages and effects will become apparent from the embodiments illustrated below. In the drawings, to which reference is made, show:
    1 shows a device according to the invention;
    2 shows another device according to the invention;
    FIG. 3 shows a further view of a device according to the invention according to FIG. 2; FIG.
    Fig. 4 is a schematic view of an apparatus for explaining a method according to the invention.
    1 shows a device 1 according to the invention for separating particles from an air stream, comprising a plurality of deposition layers 2 with a plurality of deposition elements. According to FIG. 1, the deposition elements are designed as self-contained bands 3, which are mounted on bearings 4 or enclosing them. It is favorable if two supports 4 are provided per deposition element, which are at least partially enclosed by a plurality of bands 3. The bands 3 are spaced apart from each other to deflect by air currents an airflow. It can be provided that a distance between the bands 3 is smaller than they are wide. Further, the bands 3 may be formed with a certain elasticity, so that they rest on the bearings 4. The bearings 4 may preferably be cylindrical or rod-shaped and be driven by one or more drives 5 for performing a rotational movement about its longitudinal axis. It is favorable if, per deposition layer 2, there is a drive 5, so that the bearings 4 or bands 3 of a deposition layer 2 can be set in motion independently of the bearings 4 or the bands 3 of all other deposition layers 2. Furthermore, a speed of the rotational movement of the bearings 4 per deposition layer 2 is individually adjustable. Each drive 5 may comprise means for transmitting the movements to the at least one storage 4.
    As can be seen in FIG. 1, the bearings 4 can be mounted or suspended on a frame construction 10. The device 1 may comprise any number of deposition layers 2 in order to deposit an entirety of the particles from the air stream. In addition, a number of deposition layers 2 can also be varied if they can be attached in a simple way to the frame construction 10 or detachably fastened thereto. Next, a number of bands 3 per deposition layer 2 is not limited. However, it is favorable if at least two bands 3 are provided in order to reduce a flow area of the air flow between them. The deposition layers 2 or the bands 3 thereof are arranged in particular offset from one another, so that the air flow always changes its direction and speed in a transition from one deposition layer 2 to the next.
    2, a further device 1 according to the invention is shown, wherein the deposition layers 2 are surrounded by a cover, so that a flow direction of the air flow is predetermined. The flow direction is shown in Fig. 2 by arrows. The air flow impinges on a first deposition layer 2 via an input region 8 and leaves the device via an outlet region 6. In the outlet region 6, a suction device 7, not visible in FIG. 2, can be provided for sucking in the air flow. The suction device 7 may for example be designed as a fan and accelerate the air flow in its direction. At a lower end of the device 1 or under the bands 3, a device 9 for removing the particles may be arranged. With this, the particles of the bands 3, for example, scratch off what a surface of the bands 3 may be formed accordingly. By means of the device 9 for removal in combination with the rotatable mounting 4 of the bands 3, the device 1 can be permanently in operation without it not being able to be used for separating particles for a prolonged period of time due to expensive maintenance work.
    A further view of the particle separating device 1 according to FIG. 2 is shown in FIG. 3, an inside view of which is exposed. As a result, the suction device 7 is shown in the outlet region 6.
    In a method according to the invention for separating particles from an air flow, as shown in FIG. 4, this air flow is conducted via the input region 8 onto a first of several deposition layers 2, each deposition layer 2 being formed of bands 3 arranged next to one another and spaced apart from one another.
    4 shows a schematic plan view of a device 1 according to the invention. The air flow can be guided onto the first deposition layer 2, for example at a speed of approximately 8 m / s. There, an area for the air flow is reduced because it can only flow through distances between the bands 3. This rejuvenation accelerates the air flow to, for example, 70 m / s. The particles in the air stream are usually heavier and therefore slower than the remaining air fractions, which is why they can not follow the acceleration of the air flow and bounce on the bands 3, where they adhere. Due to the spaced arrangement of the deposition layers 2 and the bands 3 of the air flow is deflected in its passage through the same over the distances again and again. The heavy particles in the accelerated air stream are too sluggish to go along with these sudden changes of direction and thus remain on the strips 3 for each deposition layer 2. It can be provided that the air flow is sucked by the suction device 7 in the outlet region 6.
    If the rotatably mounted belts 3 are rotated by means of at least one drive 5, the particles adhering to them are conveyed to a lower end of the device 1, where a device 9 for removing the particles is arranged. By means of this device 9, the particles are scratched or roped from the bands 3, whereby the bands 3 can be used permanently.
    A device 1 according to the invention is used in particular during or after a vehicle painting process, whereby a stream of air contaminated with paint or color particles is removed after the painting process or fed to the device. The lacquer particles deposited on the tapes 3 of the device 1 are removed therefrom and can subsequently be reused, for example, for the production of inferior lacquers. As a result, the "overspray" which arises in a painting process of vehicles is filtered in a simple manner and efficiently from the air stream or the air, in particular free of chemical additives.
