Definitions

  • the invention relates to a device for removing the dust-containing deposits in underground routes and in particular in inner-city tunnels with the aid of air nozzles which are assigned to a ring system and are aligned with the tunnel walls and the tunnel sole, and a suction mouth which is arranged upstream of a mobile cleaning system with a dry filter.
  • a tunnel cleaning device in which a construction is assigned to a mobile pedestal which has articulated arms which carry a cleaning roller on the inside, which is pivotably fastened and can thus perform cleaning work guided past the tunnel wall.
  • a device In the case of uneven tunnel walls and in particular also a corresponding tunnel roller, such a device cannot be used or can only be used with considerable disadvantages.
  • the DE 26 58 420 C2 discloses a device in which a brush-like roller is used and spray nozzles are used in the area of the brush to support the work of the brush. The washing liquid spraying out of the nozzles and the water lead to the undesirable wetting of the traffic area or the tunnel floor, which is particularly disadvantageous if electrical lines are laid there.
  • the GB - A - 186 970 describes a device in which, for example, compressed air is used to detach the dust-containing components, only a coarse dust separation being carried out in the associated cleaning device.
  • a train unit is known, which is primarily about cleaning the track bed.
  • This cleaning device is designed as a mobile unit arranged on a rail vehicle and has a supply of compressed air as a propellant and a direction of action in the respective Direction of travel of the rail vehicle. Such a cleaning device is not suitable for cleaning the tunnel walls.
  • the EP 08 79 919 B1 describes a method and an apparatus for cleaning tunnel walls and / or tunnel ceilings of a tunnel from dust-containing fixed deposits and from dirt.
  • a compressed air / water mixture is used, which is sprayed onto the tunnel wall or tunnel ceiling via blowing nozzles, which are assigned to a passable holder, in the direction of a nozzle hood, which absorbs the compressed air / water mixture and ensures appropriate deposition .
  • the problematic liquid is also used here, it cannot be guaranteed that the deposits, which partly consist of fine dust, are really effectively bound and sucked into the nozzle hood. Rather, it can be assumed that a large part of these fine dust particles is whirled up but remains in the air space around the device.
  • the EP 2 305 8 92 A2 on the other hand describes a device for cleaning the track superstructure and the tunnel walls, which works exclusively with compressed air.
  • the air nozzles are attached to a hood, which is moved as close as possible to the tunnel wall or the track surface or the tunnel floor, so that again it cannot be avoided that the disadvantageous and dangerous fine dust gets past the hood into the environment, and then in the whirled-up form to represent a special danger for the operating teams present in the tunnel and also for the passengers of trains. In the highly sensitized population in particular, this is seen as a disadvantage.
  • the invention is therefore based on the object of creating a mobile cleaning device for, in particular, tunnels of the inner-city traffic network, which can free the tunnel walls and the tunnel floor, in particular, from the dangerous fine dust without endangering the environment.
  • the cleaning system with a dry filter has a filter housing, which on a Transport trolley is arranged and has a plurality of filter elements, which are arranged between an inlet and an outlet nozzle and are arranged and designed to flow through the dust-laden air drawn in by a fan, the raw and clean gas channels in the filter housing guiding the filter element accesses to full advantage and are formed and wherein the cleaning nozzle for the raw gas has a suction mouth adapted to the tunnel cross-section and designed as a suction funnel, which carries a nozzle ring arranged in the working direction at a distance in front of it and at a distance from air nozzles arranged in a ring-like manner, the diameter of which corresponds to that of the outer edge of the suction funnel and additionally onto the suction funnel
  • the fan is connected behind the filter elements with a power generator, which is set up on a trolley.
  • the invention teaches that the dust whirled up by the nozzle ring or the air nozzles arranged there and, in particular, the fine dust safely reaches the suction funnel in order to get one from there certain dry filters, which ensure that not only the coarse dust, but also the very fine particles of fine dust are deposited in order to be disposed of. For this, it is important that a row of filter elements is arranged one behind the other in order to absorb the amount of air generated with the dust, in such a way that all filter elements arranged one behind the other are loaded with the air and the dust as evenly as possible.
  • the filter housing, or the raw and clean gas channels running in it run in such a way that the dust-laden air or the raw gas is introduced from the raw gas channel via the filter element accesses which can be fed accordingly, in order to there the dust-containing material on the tissue to deposit. They are deposited on the outside of the filter elements, so that the dust can be removed with compressed air if necessary, so that they can then be disposed of.
  • the finest dust particles and also the coarser dust are safely detached from the tunnel walls and also the tunnel floor and then fed specifically to the suction funnel, because the air nozzles are attached or arranged on a correspondingly large nozzle ring.
  • This ring of nozzles is in particular ring-shaped because, even with oval or slightly different cross-sections, the compressed air can still be safely applied to the tunnel walls.
  • the necessary compressed air is generated by a compressor, while the suction process is carried out by a fan, which is arranged behind the filter elements and is designed via a power generator so that it can also perform well. Since the circumference of the nozzle ring and the suction funnel are of the same design, it is ensured that the whirled up dirt and in particular the fine dust get safely into the suction funnel in order to then be precipitated accordingly in the filter elements.
  • the air nozzles are directed not only at the tunnel wall and the tunnel floor, but also at the suction funnel, so that this targeted diversion of the whirled up material into the suction funnel and the filter elements is ensured.
  • the desired precipitation of even the finest fine dust is ensured by the fact that the raw gas duct and the clean gas duct arranged in the filter housing between the inlet and outlet nozzle are arranged horizontally one above the other and are separated from one another by a partition that runs horizontally and forms the entire filter housing horizontally, the partition from the inlet nozzle towards the outlet nozzle is formed at an angle to the roof of the filter housing and the filter elements are connected to the partition and / or the frame structure of the filter housing.
  • the filter housing can be constructed with small heights, although the raw gas and clean gas channels are arranged one above the other.
  • the clean gas duct is designed to run above and to the side of the raw gas duct, so that the cleaned air can flow past the raw gas duct into the clean gas duct region above it, without there being any disadvantageous increases in the air flow velocity.
  • the device provides that some of the air nozzles on the nozzle ring are arranged and designed as tunnel wall nozzles pointing to the tunnel walls and sole and another part as funnel nozzles pointing to the suction funnel.
  • the number of both air nozzle types is preferably approximately the same, with some tunnel wall nozzles being used less so that the two air streams support one another and do not impair one another.
  • the funnel nozzles should be arranged so that they point towards the suction funnel, specifically at the lowest point of the suction funnel, so that a suction is created for the dusty air.
  • tunnel wall nozzles and the funnel nozzles are arranged alternately on the nozzle ring, the number of tunnel wall nozzles being, as mentioned, slightly less than that of the funnel nozzles. This arrangement of the nozzles leads to an optimally uniform air flow right at the beginning of the suction funnel.
  • the parts of the dry filter are assigned to a transport trolley and the other units to a further transport trolley, where they are expediently designed to be suitable for rail traffic and / or road traffic and are designed to be coupled to a diesel or E-Lock or a road vehicle.
  • the movement of the cleaning device can be influenced in a targeted manner via the towing vehicle, so that any changes in cross section or the like can be reacted to immediately.
  • the power generator for the fan is assigned to a transport trolley, namely a separate transport trolley on which, according to the development of the invention, a compressor for supplying the air nozzles and for cleaning the filter elements is also arranged.
  • the dust, and in particular the fine dust is deposited on the filter surfaces and can be removed by compressed air blasts and then disposed of. It is advantageous that the fine dust is always in a mixture with the coarser dust, so that it is no longer a hazard simply because it is also deposited on this coarse dust, and can then be deposited together with this on the walls of the filter elements.
  • the invention provides that the outlet connection for the clean gas has one or more connections for air ducts, which are positioned in the working direction in front of the nozzle ring. The remaining air at the outlet for the clean gas then no longer poses any problems.
  • the invention provides that a carrier holding the nozzle ring is adjustable in length and at the same time the fan is designed to be adjustable in terms of performance.
  • the filter elements are connected to the outer wall of the filter housing and / or the transport carriage via a copper strand, bypassing an elastic sealing bead. As a result, negative electrical charging of the interior of practically every individual filter element can be reliably avoided.
  • the suction funnel and the nozzle ring can be adapted to the changing conditions in the tunnel or the route, but also the dry filter.
  • the partial housing can be expanded or reduced in the longitudinal direction of the device.
  • partitions are expandable, for example, so that one strand or both strands or alternately the filter strands can be used when the filter housings are next to one another.
  • Another way of increasing the performance of the dry filter is to use two filter elements and, accordingly, filter housings next to each other and At the same time, two filter elements must be joined together to form a structural unit, so that practically four strands or more are created. This enables even better adaptability to changing air and dust loads.
  • the invention is characterized in particular by the fact that a tunnel cleaning device is created with which the dust-containing and in particular fine dust-containing air generated during tunnel cleaning can be safely collected and made "harmless", that is to say in particular the dangerous fine dust is also passed into suitable dry filters where it is deposited together with the coarser dust and made disposable.
  • a tunnel cleaning device With the help of such a tunnel cleaning device, tunnels with a round or oval cross-section can be safely and easily cleaned, specifically avoiding loosening and disposing of slimy or stuck dust from the tunnel walls, because such a coating also has the advantage that the in the passing air containing dust and in turn the fine dust is collected and held so that a natural dedusting of the air is possible.
  • FIG. 1 shows a tunnel cleaning device 1, which is designed to be movable on rails in a tunnel 2.
  • a series of air nozzles 4, 5, 6 and 7 are assigned to a ring system 3.

  • the cleaning system 10 is designed here as a dry filter 11, which consists of several partial housings 62, 63, 64 arranged one behind the other.
  • a suction mouth 12 or a suction funnel 34 is provided for receiving the dust-containing air. This suction funnel 34 is arranged and designed in such a way that it can safely pick up the dust whirled up by the nozzle ring 36 or the ring system 3 with the air nozzles 4-7 and also the fine dust.
  • FIG. 2 shows this part of the tunnel cleaning device 1 in an enlarged representation.
  • the suction funnel 34 is composed of individual elements, a circular cross section of a tunnel 2 being provided for this.
  • the dimensions of the outer edge 37 correspond to that of the nozzle ring 36, the nozzle ring 36 being equipped with a large number of air nozzles 4-7.
  • These nozzles are arranged differently, in particular Figure 2

  • a plurality of filter elements 16, 17 are accommodated in the individual partial housings 62, 63, 64, which pass through the raw gas channel 26 with raw gas 30 are supplied.
  • Raw gas 30 here is the substantial amount of dust-containing air.
  • this raw gas is released again into the air flow via the outlet connection 19.
  • one or more connections 49 are provided for ventilation. These ducts lead the air back towards the nozzle ring 36 and release these air quantities there again.
  • the fan 20 which is followed by a frequency converter 21 and then a pipe in the direction of the outlet nozzle 19.
  • the air which is still heavily contaminated by dust in the region of the inlet nozzle 18, practically contains dust when it passes through the outlet nozzle 19 no more dust, especially no more fine dust. Therefore, this air can be released into the rest of the air flow without any problems.
  • Another transport carriage 23 is arranged between the transport carriage 15 with the filter housing 14 and thus the cleaning system 10 and the E-Lock 47, on which the power generator 24 and a compressor 25 are arranged.
  • the power generator 24 supplies the fan 20, while the compressor 25 ensures that the air nozzles 4-7 are supplied with the necessary compressed air and also ensures that sufficient compressed air is available to separate the individual filter elements 16, 17 from the to remove coarse and fine dust. This dust then falls into a dust conveyor 65, which will be explained later.
  • Figure 3 shows a circular tunnel 2, in which a cleaning system 10 works.
