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 arranged behind the ring system 3 in the working direction 35 and is assigned to a transport carriage 15.

- 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.

Abstract
Für die Entfernung der staubhaltigen Ablagerungen in untertägigen Strecken und in insbesondere innerstädtischen Tunnel ist eine Tunnelreinigungsvorrichtung 1 vorgesehen, die über einen Trockenfilter 11 mit einer Vielzahl von Filterelementen 16, 17 verfügt. Das aus mehreren Teilgehäusen 62, 63, 64 bestehende Filtergehäuse 14 ist einem Transportwagen 15 zugeordnet, der zusammen mit einem zweiten Transportwagen 23 die nötigen Versorgungsteile für diesen Trockenfilter 11 trägt und auf Schienen 29 oder auch auf dem Tunnelboden verfahrbar ist. Zur Lösung des insbesondere Feinstaubes, der auf der Tunnelwand 8 und auf der Tunnelsohle 9 sich abgelagert hat, wird er durch einen Düsenkranz 36 mit zwei Sorten von Luftdüsen 4-7 aufgewirbelt und über den dabei entstehenden und den durch sogenannte Trichterdüsen 44 erzeugten Luftstrom in einen Saugtrichter 34 hineingesaugt, um dann in dem schon erwähnten Trockenfilter 11 entstaubt zu werden. Durch gleichmäßige Beschickung der im Filtergehäuse 14 angeordnete Filterelemente 16, 17 kann die Luftgeschwindigkeit soweit reduziert werden, dass ein sicheres Ablagern insbesondere der Feinstäube sicher erfolgen kann. Dieser Feinstaub wird dann zusammen mit den anderen Staubbestandteilen durch Druckluft vom Filtergewebe abgereinigt und kann problemlos entsorgt werden, insbesondere ohne wieder in die Umgehungsluft zu gelangen, wie das beim Stand der Technik immer wieder erfolgt ist.A tunnel cleaning device 1, which has a dry filter 11 with a large number of filter elements 16, 17, is provided for removing the dust-containing deposits in underground routes and in particular in inner-city tunnels. The filter housing 14 consisting of a plurality of partial housings 62, 63, 64 is assigned to a transport carriage 15 which, together with a second transport carriage 23, carries the necessary supply parts for this dry filter 11 and can be moved on rails 29 or on the tunnel floor. To solve the particulate matter in particular, which has deposited on the tunnel wall 8 and on the tunnel sole 9, it is whirled up by a nozzle ring 36 with two types of air nozzles 4-7 and into one via the air flow that is created and that is generated by so-called funnel nozzles 44 Suction funnel 34 sucked in, in order to then be dedusted in the dry filter 11 already mentioned. By evenly loading the filter elements 16, 17 arranged in the filter housing 14, the air speed can be reduced to such an extent that the fine dust, in particular, can be deposited safely. This fine dust is then cleaned together with the other dust components by compressed air from the filter fabric and can be disposed of without any problems, in particular without getting back into the bypass air, as has always been the case in the prior art.
Description
Die Erfindung betrifft eine Vorrichtung zum Entfernen der staubhaltigen Ablagerungen in untertägigen Strecken und in insbesondere innerstädtischen Tunnel mit Hilfe von Luftdüsen, die einem Ringsystem zugeordnet und auf die Tunnelwände und die Tunnelsohle ausgerichtet sind, und einem Saugmund, der einem fahrbaren Reinigungssystem mit Trockenfilter vorgeordnet ist.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.
Aus der
Die
The
Der Erfindung liegt daher die Aufgabe zu Grunde, eine mobile Reinigungsvorrichtung für vor allem Tunnel des innerstädtischen Verkehrsnetzes zu schaffen, die die Tunnelwände und den Tunnelboden vor allem von dem gefährlichen Feinstaub ohne Gefährdung der Umwelt befreien kann.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.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Reinigungssystem mit Trockenfilter ein Filtergehäuse aufweist, das auf einem Transportwagen angeordnet ist und über eine Mehrzahl von Filterelementen verfügt, die zwischen einem Eingangs- und einem Ausgangsstutzen angeordnet und von der staubhaltigen, von einem Ventilator angesaugten Luft durchströmbar angeordnet und ausgebildet sind, wobei die Roh- und Reingaskanäle in dem Filtergehäuse die Filterelementzugänge voll ausnutzend geführt und ausgebildet sind und wobei der Reinigungsstutzen für das Rohgas einen dem Tunnelquerschnitt angepassten als Saugtrichter ausgebildeten Saugmund aufweist, der einen in Arbeitsrichtung im Abstand davor angebrachten Düsenkranz im Abstand ringartig angeordneter Luftdüsen trägt, dessen Durchmesser dem des Außenrandes des Saugtrichters entspricht und dem zusätzlich auf den Saugtrichter gerichtete Luftdüsen angeordnet sind, wobei der Ventilator hinter den Filterelementen mit einem Stromerzeuger verbunden ist, der auf einem Transportwagen aufgestellt ist.The object is achieved in that 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 Directional air nozzles are arranged, wherein the fan is connected behind the filter elements with a power generator, which is set up on a trolley.
Während bei der
Das gewünschte Niederschlagen auch des feinsten Feinstaubes ist dadurch sichergestellt, dass die im Filtergehäuse zwischen Eingangs- und Ausgangsstutzen angeordneten Rohgaskanal und Reingaskanal horizontal übereinanderliegend angeordnet und durch eine darin verlaufende, die gesamte Filtergehäusehorizontale bildende Trennwand voneinander getrennt sind, wobei die Trennwand vom Eingangsstutzen in Richtung Ausgangsstutzen schräg zum Dach des Filtergehäuses hochführend ausgebildet ist und wobei die Filterelemente mit der Trennwand und/oder der Rahmenkonstruktion des Filtergehäuses verbunden sind. Damit ist sichergestellt, dass die Filterelementzugänge für das angesaugte Luft-/Staubgemisch auf jeden Fall immer erreichbar sind und zwar über die gesamte zur Verfügung stehende Fläche, wobei durch die Neigung der Trennwand oder besser gesagt das Ansteigen der Trennwand den Gegebenheiten Rechnung getragen wird, dass die vom Luftstrom zunächst belasteten Filterelemente einen größeren Teil des Luftstroms aufnehmen als die am Ende des Rohgaskanal angeordneten Filterelemente. Der Verlauf der Trennwand gleicht diesen Effekt aus. Die notwendige Geschwindigkeit bzw. Führung des Luftstroms ist dabei gewährleistet. Insgesamt ist dadurch vorteilhaft erreicht, dass mit einer geringeren Luftgeschwindigkeit gearbeitet werden kann, was die Ablagerung der staubhaltigen Bestandteile im Luftstrom am Filtergewebe verbessert. Vorteilhaft ist weiter, dass auf Grund dieser Ausbildung mit geringen Bauhöhen beim Filtergehäuse gearbeitet werden kann, obwohl Rohgas- und Reingaskanal übereinander verlaufend angeordnet sind.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. This ensures that the filter element accesses for the sucked-in air / dust mixture are always accessible and in any case over the entire available area, whereby the inclination of the partition wall or rather the rise of the partition wall takes into account the fact that the filter elements initially loaded by the air flow absorb a larger part of the air flow than the filter elements arranged at the end of the raw gas duct. The course of the Partition compensates for this effect. The necessary speed or guidance of the air flow is guaranteed. Overall, this advantageously means that a lower air speed can be used, which improves the deposition of the dust-containing components in the air flow on the filter fabric. It is also advantageous that, due to this design, the filter housing can be constructed with small heights, although the raw gas and clean gas channels are arranged one above the other.
In einer vorteilhaften Optimierung des Trockenfilters ist vorgesehen, dass der Reingaskanal oberhalb und seitlich des Rohgaskanals verlaufend ausgebildet ist, sodass die gereinigte Luft am Rohgaskanal vorbei in den darüber liegenden Reingaskanalbereich strömen kann, ohne dass es zu nachteiligen Steigerungen der Luftstromgeschwindigkeit kommt.In an advantageous optimization of the dry filter, it is provided that 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.
Wie schon weiter vorne erwähnt, ist bei der Vorrichtung vorgesehen, dass ein Teil der Luftdüsen auf dem Düsenkranz als Tunnelwanddüsen auf die Tunnelwände und die -sohle und ein weiterer Teil als Trichterdüsen auf den Saugtrichter weisend angeordnet und ausgebildet sind. Vorzugweise ist die Zahl beider Luftdüsenarten annähernd gleich, wobei einige Tunnelwanddüsen weniger zum Einsatz kommen, sodass sich die beiden Luftströme unterstützen und nicht beeinträchtigen. Dabei sollten die Trichterdüsen auf den Saugtrichter hin zuweisend angeordnet werden und zwar auf das Tiefste des Saugtrichters, sodass ein Sog für die staubhaltige Luft erzeugt wird.As already mentioned further above, 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.
In einer weiteren zweckmäßigen Ausbildung der Erfindung ist vorgesehen, dass die Tunnelwanddüsen und die Trichterdüsen abwechselnd auf dem Düsenkranz angeordnet sind, wobei wie erwähnt die Zahl der Tunnelwanddüsen geringfügig geringer ist als die der Trichterdüsen. Diese Anordnung der Düsen führt zu einem optimal gleichmäßigen Luftstrom schon am Anfang des Saugtrichters.In a further expedient embodiment of the invention, it is provided that the 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.
Die Teile des Trockenfilters sind einem Transportwagen zugeordnet und die übrigen Aggregate einem weiteren Transportwagen, wobei sie zweckmäßigerweise für den Schienenverkehr und/oder den Straßenverkehr geeignet ausgebildet und mit einer Diesel- oder E-Lock oder einem Straßenverkehrszugfahrzeug koppelbar ausgeführt sind. Über das Zugfahrzeug kann die Bewegung der Reinigungsvorrichtung gezielt beeinflusst werden, sodass bei auftretenden Änderungen im Querschnitt oder ähnlichem sofort reagiert werden kann.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.
Weiter vorne ist erwähnt, dass der Stromerzeuger für den Ventilator einem Transportwagen zugeordnet ist und zwar einem gesonderten Transportwagen, auf dem gemäß der Weiterbildung der Erfindung auch ein Kompressor für die Versorgung der Luftdüsen und für die Säuberung der Filterelemente angeordnet ist. Der Staub und dabei insbesondere auch der Feinstaub wird auf den Filterflächen abgelagert und kann durch Druckluftstöße gezielt abgelöst und dann entsorgt werden. Vorteilhaft ist, dass der Feinstaub immer im Gemisch mit dem gröberen Staub ist, sodass er allein schon dadurch, dass er sich auch auf diesem Grobstaub ablagert, keine Gefährdung mehr darstellt, und sich dann mit diesem zusammen auf den Wänden der Filterelemente ablagern kann.It is mentioned further above that 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.
Um Probleme bei der Weiterführung der Luft aus der Reinigungsvorrichtung zu vermeiden, sieht die Erfindung vor, dass der Ausgangsstutzen für das Reingas einen oder mehrere Anschlüsse für Lutten aufweist, die in Arbeitsrichtung vor den Düsenkranz austragend positioniert sind. Die verbleibende am Ausgang für das Reingas austretende Luft bringt dann keine Probleme mehr.In order to avoid problems with the continuation of the air from the cleaning device, 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.
Weiter vorne ist bereits darauf hingewiesen worden, dass bei Änderungen des Tunnelquerschnitts Möglichkeiten bestehen sollten, den Saugtrichter bzw. den Düsenkranz entsprechend anzupassen, was dadurch möglich ist, dass der Saugtrichter und der Düsenkranz durch Aufsätze oder Erweiterungsstücke im Durchmesser erweiterbar und der Ventilator leistungsmäßig anpassbar ausgebildet sind. Mit der Erweiterung des Düsenkranzes und des Saugtrichters muss der Druckluftanfall vergrößert werden, was über den Kompressor erreicht wird, gleichzeitig muss aber auch die Menge der eingesaugten Luft vergrößert werden, was durch den Ventilator möglich wird.It has already been pointed out earlier that when the tunnel cross-section changes, there should be possibilities to adapt the suction funnel or the nozzle ring accordingly, which is possible because the suction funnel and the nozzle ring can be expanded in diameter by means of attachments or extension pieces and the fan can be designed to be adaptable in terms of performance are. With the expansion of the nozzle ring and the suction funnel the amount of compressed air must be increased, which is achieved via the compressor, but at the same time the amount of air drawn in must also be increased, which is made possible by the fan.
Um auch den Abstand zwischen Düsenkranz und Saugtrichter anpassen zu können, sieht die Erfindung vor, dass ein den Düsenkranz haltender Träger in der Länge verstellbar und gleichzeitig der Ventilator leistungsmäßig anpassbar ausgebildet ist.In order to also be able to adapt the distance between the nozzle ring and suction funnel, 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.
Um Probleme in den Filterelementen bzw. im Filtergehäuse zu vermeiden, ist vorgesehen, dass die Filterelemente über eine Kupferlitze unter Umgehung einer elastischen Dichtwulst mit der Außenwandung des Filtergehäuses und /oder dem Transportwagen verbunden sind. Dadurch kann eine negative elektrische Aufladung des Innenraums praktisch jedes einzelnen Filterelementes sicher vermieden werden.In order to avoid problems in the filter elements or in the filter housing, it is provided that 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.
Nicht nur der Saugtrichter und der Düsenkranz können sich den sich ändernden Gegebenheiten im Tunnel bzw. der Strecke angepasst werden, sondern auch der Trockenfilter. Dies ist möglich, weil jeweils mehrere Filterelemente einem Teilgehäuse zugeordnet sind. Die Teilgehäuse können in Längsrichtung der Vorrichtung erweitert oder auch verringert werden. Darüber hinaus besteht erfindungsgemäß die Möglichkeit, zwei Filtergehäuse ohne Zwischenwand nebeneinander stehend zu einer Baueinheit zusammenzufügen und auf senkrechte Zwischenwände bei Roh- und Reingaskanal zu verzichten. Dadurch entsteht ein großer Filterraum, der sich ändernde Luftmengen problemlos bewältigen kann. Denkbar ist es auch, dass solche Zwischenwände beispielsweise ausdehnbar sind, sodass man bei den nebeneinander stehenden Filtergehäusen bei Bedarf einen Strang oder beide Stränge oder auch wechselnd die Filterstränge zum Einsatz bringen kann.Not only 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. This is possible because several filter elements are assigned to a partial housing. The partial housing can be expanded or reduced in the longitudinal direction of the device. In addition, according to the invention, there is the possibility of joining two filter housings standing side by side without a partition to form a structural unit and to dispense with vertical partition walls for the raw and clean gas duct. This creates a large filter room that can easily handle changing air volumes. It is also conceivable that such 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.
Eine weitere Möglichkeit, der Vergrößerung der Leistung des Trockenfilters ist die, zwei Filterelemente und dementsprechend Filtergehäuse nebeneinander und gleichzeitig zwei Filterelemente jeweils übereinander zu einer Baueinheit zusammen zu fügen sind, sodass praktisch vier Stränge entstehen oder auch mehr. So ist eine noch bessere Anpassbarkeit an sich ändernde Luft- und Staubbelastungen möglich.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.
Die Erfindung zeichnet sich insbesondere dadurch aus, dass eine Tunnelreinigungsvorrichtung geschaffen ist, mit der die bei der Tunnelreinigung erzeugte staubhaltige und insbesondere Feinstaub enthaltende Luft sicher aufgefangen und "unschädlich" gemacht werden kann, das heißt insbesondere auch der gefährliche Feinstaub wird in dafür geeignete Trockenfilter geleitet, wo er zusammen mit dem gröberen Staub niedergeschlagen und entsorgbar gemacht wird. Mit Hilfe einer derartigen Tunnelreinigungsvorrichtung können Tunnel mit rundem oder ovalem Querschnitt problemlos sicher gereinigt werden, wobei gezielt darauf verzichtet wird, schleimartigen oder festgebackenen Staub mit von dem Tunnelwänden zu lösen und zu entsorgen, weil eine solche Beschichtung ja auch den Vorteil hat, dass der in der vorbeistreichenden Luft enthaltende Staub und dabei wiederum der Feinstaub aufgefangen und festgehalten wird, sodass eine natürliche Entstaubung der Luft möglich ist.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. 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.

In den einzelnen Teilgehäusen 62, 63, 64 sind eine Mehrzahl von Filterelementen 16, 17 untergebracht, die über den Rohgaskanal 26 mit Rohgas 30 versorgt werden. Rohgas 30 ist hier die erhebliche Mengen Staub enthaltende Luft. Dieses Rohgas wird nach Durchlaufen der Filterelemente 16, 17 und Passieren des Ventilators 20 über den Ausgangsstutzen 19 wieder in den Luftstrom entlassen. Um hier Probleme bzgl. des Luftstroms in dem Tunnel zu vermeiden, sind ein oder mehrere Anschlüsse 49 für Lutten vorgesehen.
