Abstract
Description
Die vorliegende Erfindung betrifft Verfahren und Vorrichtung zur sicheren und schnellen Entfernung von Verschmutzungsschichten vorzugsweise bei Tunnelwänden und -böden.The present invention relates to methods and apparatus for the safe and rapid removal of soiling layers preferably in tunnel walls and floors.
Es ist bereits beschrieben worden, daß Verschmutzungen, auch Farbreste von Oberflächen abgetragen bzw. entfernt werden können, indem man diese Oberflächenschichten mit einem Lösungsmittel auflöst. Hierbei werden - je nach Anwendungsfall - auch zusätzliche Flüssigkeiten, die mit dem Lösungsmittel nicht mischbar sind, jedoch andere Benetzungskräfte zum Beschichtungssubstrat hin aufweisen, genutzt.It has already been described that contaminants, even paint residues from surfaces can be removed or removed by dissolving these surface layers with a solvent. Depending on the application, additional fluids which are immiscible with the solvent but which have other wetting forces towards the coating substrate are used here.
Die Oberflächen von Metalltanks, auf denen sich z. B. Bitumenreste befinden, werden auch noch mit mechanischen Methoden gereinigt. Hierbei werden z. B. die Ablagerungen mittels Hämmern abgeschlagen, was jedoch nur in der kalten Jahreszeit effektiv möglich ist, wenn die Ablagerungen ausreichend hart sind.The surfaces of metal tanks on which z. As bitumen residues are also cleaned with mechanical methods. This z. B. the deposits knocked off by hammering, but only in the cold season is effectively possible if the deposits are sufficiently hard.
Bei hochviskosen Verschmutzungen werden auch Hochdruckwasserstrahlen benutzt, die mit Drücken von 200 bis über 1.000 bar arbeiten. Der Wasserstrahl wird hierbei mittels Rund-, Flach- oder Rohrstrahldüsen erzeugt, wobei das Arbeitsmedium in einer Trenneinrichtung abschließend von den Reinigungsrückständen separiert wird. Der Nachteil der Hochdruckwasserstrahlreinigung liegt z. B. darin, daß Wassernebel bzw. -dampf entsteht, welcher die Korrosion an ungeschützten Stellen fördert und Störungen an der elektrischen Ausrüstung produziert. Auch die Ablösung mittels speziell angepaßter chemischer Mittel scheidet in den meisten Fällen wegen Gefährdung des Reinigungspersonals und der näheren Umwelt aus.For highly viscous contaminants, high-pressure water jets operating at pressures of between 200 and over 1,000 bar are also used. The water jet is generated here by means of round, flat or tube jet nozzles, wherein the working medium is finally separated in a separating device of the cleaning residues. The disadvantage of high-pressure water jet cleaning is z. Example, in that water mist or vapor is formed, which promotes corrosion in unprotected areas and produces interference with the electrical equipment. Also, the replacement by means of specially adapted chemical agents is eliminated in most cases due to endangerment of the cleaning staff and the nearer environment.
Besonders bei Eisenbahn-, U-Bahn-Tunnelsystemen usw., die z. T. über Jahrzehnte stark benutzt werden, führt dies zu Problemen. Als Gefährdungssituationen seien z. B. aufgeführt:
- Drohende Tunnelbrände
- Ausfall von Elektroantrieben durch Emissionen (Kurzschlußgefahr)
- Erhöhter Verschleiß des Schienensystems
- Ansammlung gesundheitsgefährdender Stoffe und deren Aufnahme durch Personal und Fahrgäste.
- Threatening tunnel fires
- Failure of electric drives due to emissions (risk of short-circuit)
- Increased wear of the rail system
- Collection of hazardous substances and their uptake by personnel and passengers.
Abhilfe schafft hier nur eine regelmäßige, kontinuierliche Reinigung aller Tunnelbereiche, möglichst ohne den Fahrbetrieb zu stören.Remedy here only a regular, continuous cleaning of all tunnel areas, if possible without disturbing the driving.
Der Erfindung liegt daher die Aufgabe zugrunde, ein schnelles, einfaches und effektives Reinigungsverfahren und -system zur Verfügung zu stellen, welches z. B. Betonstaub aus Tunnelbereichen, ebenso stark verschmutzte bzw. verölte ältere Tunnelbereiche bzw. Funktionseinrichtungen in einem Arbeitsgang wasserfrei säubert, elektrische Anlagen, Schaltkästen, Kontakte keiner Deaktivierung bedürfen, wobei die erwünschte Sandstrahlwirkung verstärkt wird durch eine sichere Schnellentfernung flächiger Schmutzschichtteile und keine störenden Strahlmittelreste nach dem Säuberungsvorgang zusätzlich entfernt werden müssen.The invention is therefore an object of the invention to provide a fast, simple and effective cleaning process and system available, which z. B. concrete dust from tunnel areas, equally heavily polluted or oily older tunnel areas or functional equipment cleans in an operation anhydrous, electrical systems, switch boxes, contacts do not require deactivation, the desired sandblasting is enhanced by a safe quick removal flat dirt layer parts and no disturbing blasting agent residues must be removed in addition to the cleaning process.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Strahl- bzw. Reinigungsmittel CO2-Trockeneis eingesetzt wird, wobei dieses mit hoher Geschwindigkeit, z. B. mit Schallgeschwindigkeit, mittels der Schleuderräder auf die zu säubernde Fläche aufgetragen wird und durch den Schockgefriereffekt des Schmutzbelages, verbunden mit Versprödung und Rißbildung, in der Schmutzschicht der Eispelletstaub unter die abzutragende Schicht gelangt und durch die explosionsartige Änderung des Aggregatzustandes des CO2-Eises die Schmutzschicht abgesprengt wird. Die trockenen, spröden Schmutzpartikel fallen hierbei auf den Tunnelboden und können somit - rückstandsfrei - im gleichen Arbeitsgang abgesaugt werden.The object is achieved in that is used as blasting or cleaning CO2 dry ice, which at high speed, z. B. with the speed of sound, by means of the centrifugal wheels is applied to the surface to be cleaned and passes through the Schockgefriereffekt of dirt, associated with embrittlement and cracking, in the dirt layer of Eispelletstaub under the ablated layer and the explosion-like change in the state of matter of the CO2-ice Dirt layer is blasted off. The dry, brittle dirt particles fall onto the tunnel floor and can therefore be vacuumed - leaving no residues - in the same operation.
Verbessert wird dieser Reinigungseffekt dadurch, daß durch den kinetischen Effekt beim Auftreffen der Eispartikel auf die zu reinigende Oberfläche Schmutzteile abgeschlagen bzw. abgerieben werden.This cleaning effect is improved by the fact that by the kinetic effect when the ice particles hit the surface to be cleaned debris are aborted or abraded.
Bei einer erfindungsgemäßen Variante sind die Schleuderräder innerhalb der konstruktiv vorgegebenen Grenzen beweglich angeordnet, so daß durch eine Änderung der Strahlrichtung Anpassung an die örtlichen Gegebenheiten möglich ist.In a variant according to the invention, the blast wheels are movably arranged within the design limits, so that adaptation to the local conditions is possible by changing the direction of the blast.
Das Strahlmittel liegt üblicherweise in Pelletform vor und wird in einem konstruktiv und thermisch dafür optimierten Vorratsbehälter vom System mitgeführt und die notwendige Strahltemperatur von ≤ - 79° C sichergestellt.The abrasive is usually in pellet form and is carried in a structurally and thermally optimized storage tank by the system and the necessary jet temperature of ≤ - 79 ° C ensured.
Zur Optimierung der Verfahrensparameter kann mit einer Schleuderradzahl von 3 - 6 gearbeitet werden, wobei diese Schleuderräder integrierte Leitelemente besitzen, welche eine Richtungssteuerung des Strahlmittels ermöglichen und darüber hinaus durch den selektiven und steuerbaren Einsatz der Steuerräder wahlweise Tunneldecke, Seitenwände, Tunnelboden oder auch die 3 Flächen simultan gereinigt werden können.To optimize the process parameters can be used with a blast wheel number of 3 - 6, these blasters have integrated vanes, which allow directional control of the blasting agent and beyond by the selective and controllable use of steering wheels optional tunnel ceiling, side walls, tunnel floor or the 3 surfaces can be cleaned simultaneously.
