    The invention relates to a cleaning installation for rolling vehicles, especially railway vehicles.
    To clean railway vehicles of various types of dirt, it is known to circulate them in cleaning corridors in which cleaning with jets of high pressure liquid is carried out to detach the dirty particles from the surfaces of the vehicle. It is particularly known from US-A-2006/0060217 to project high speed and high pressure snow jets obtained from compressed air or liquid nitrogen mixed with chilled water. However, the use of water for cleaning presents various problems such as water consumption, which can be problematic in some countries, the need for a water circulation circuit and its complexity, and the risk of training. rust on cleaned vehicles.
    It is also known from KR-A-10 1278799 to clean the bottom part of a railway vehicle by high speed and high pressure spraying of a dry ice jet made from carbon dioxide allowing take off the dirt particles and evacuate them with a high-pressure air jet. It is also known from DE-A-1 99 43 832 to clean the interior of a railway vehicle which has undergone a fire by the projection of dry ice obtained from carbon dioxide. However the use of carbon dioxide implies a risk of explosion in closed space, and is toxic for people who may be near the cleaned vehicle. Steam or gas can accumulate in large and dangerous concentrations, particularly close to the ground, the gas being heavier than air, and especially in closed spaces, if the ventilation is not adapted. It is these drawbacks that the invention intends to remedy by proposing a new rolling vehicle cleaning installation, in which the risks associated with the use of carbon dioxide are better controlled and the risks of accidents are reduced. To this end, the invention relates to a cleaning installation for rolling vehicles, in particular railway vehicles, comprising a storage tank for carbon dioxide in the liquid state, a compressor-air dryer, an ice-making machine carburettor fed by the tank and the compressor dryer, a cleaning corridor in which the vehicles are introduced, and dry ice blasting devices on the vehicles. This facility is characterized in that it also includes a system for controlling the atmosphere of the cleaning corridor, including a carbon dioxide detector in the corridor, a carbon dioxide suction system and a ventilation system. , the carbon dioxide aspiration system and the ventilation system being adapted to be controlled according to the amount of carbon dioxide measured in the corridor by the carbon dioxide detector.
    Thanks to the invention, the carbon dioxide content in the atmosphere of the cleaning corridor is continuously monitored and controlled, which considerably reduces the risk of explosion or intoxication.
    According to advantageous but non-obligatory aspects of the invention, such an installation may incorporate one or more of the following features, taken in any technically permissible combination: - The installation comprises a detector adapted to detect the entrance of a vehicle rolling in the cleaning corridor and automatically trigger the dry ice blasting devices. - The dry ice making machine is a pelletizer. - Dry ice is manufactured in the form of pellets, snow, pellets or rods. - Dry ice blasting devices include multiple nozzle jets on two opposite sides of the corridor. - The corridor includes a railway adapted to guide rail vehicles in the corridor. The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a cleaning facility called "parade" or "stop & Go >> of vehicles, made by way of non-limiting example with reference to Figure 1 attached showing a schematic view of a cleaning installation according to the invention during the cleaning of a rolling vehicle.
    Figure 1 shows a facility 1 cleaning "parade" of vehicles, particularly suitable for cleaning railway vehicles. The installation 1 comprises a cleaning corridor 9, in which the rolling vehicles are introduced. The installation 1 uses the principle of the projection of dry ice on vehicles to detach the dirt and evacuate. Dry ice is made from carbon dioxide, which avoids the use of water and reduces the environmental impact of cleaning. The installation 1 comprises for this purpose a storage tank 3 for carbon dioxide in the liquid state and an air dryer compressor 5. The tank 3 is located outside the cleaning corridor 9 and is placed on a reinforced specific slab. The reservoir 3 stores the liquid carbon dioxide at a suitable temperature to minimize evaporation thereof, for example of the order of 86 ° C. Near the tank 3, another slab dedicated to unloading, accepts loads of at least 26 tons for refueling truck liquid carbon dioxide. The air-dryer 5 is supplied with ambient air by an unrepresented air inlet. Alternatively, the air can be compressed and then dried, or vice versa, in two separate equipment.
    The tank 3 and the drying compressor 5 are both connected by pipes C1 and C2, the shortest possible and covered with insulating sheath, to a dry ice machine 7. From the carbon dioxide in the liquid state and the compressed and dried air produced by the dryer compressor 5, the machine 7 produces dry ice which is dry ice to the extent that it does not contain water, which is then conveyed to the cleaning corridor 9 .
    The dry ice making machine 7 is preferably a pelletizer. Advantageously, the dry ice is manufactured in the form of granules, snow, pellets or rods.
    A rolling vehicle 100 is represented in the cleaning corridor 9. The rolling vehicle 100, which is a railway vehicle, is introduced into the corridor 9 in a direction represented by the arrow Fl and is supported by two rails 91 crossing the cleaning corridor. 9.
    The cleaning corridor 9 forms a closed space whose only openings 92 and 93 are provided at its ends to allow entry and exit of the rolling vehicle 100. The openings 92 and 93 are, for example, provided with automatically controlled doors and electrically powered from photocells. Thus, the openings 92 and 93 can be closed during the cleaning of a rolling vehicle 100 to close the cleaning corridor 9 and to avoid the dispersion of carbon dioxide and dirt around.
    The cleaning corridor 9 comprises devices, advantageously rotating about a vertical axis, as represented by the double arrows F 2, of dry ice blasting on the rolling vehicle 100. These projection devices are formed in this example by two multiple jet nozzles 11 and 13 disposed on two opposite sides of the corridor 9, each at one end of the cleaning corridor 9. In this example, the jets 11 and 13 are disposed on each side of the rails 91, and respectively supplied with dry ice by pipes C3 and C4 in which the dry ice flows from the machine 7. The pipes C3 and C4 are sized to be as short as possible and covered with insulating sheath.
    As a variant not shown, the jets with multiple nozzles 11 and 13 can be arranged on two opposite sides of the corridor 9, facing one another at one of its ends, for example close to the opening 92.
    The function of cleaning the outer surfaces of the rolling vehicle 100 is essentially performed in three stages, for example, in the case where carbon dioxide is produced in the form of pellets: • Projection of the pellets at a very low temperature, for example the order of -78 ° C, which causes a thermal shock which has the effect of retracting dirt, • Impact and liquefaction of pellets, stains coming off, • Sublimation of pellets and blast effect, dirt coming off.
    Carbon dioxide proves dangerous or even deadly for humans from a certain concentration value in the air. The limit value of exposure not to be exceeded is 3% in concentration rate in air for a maximum of 15 minutes. In accordance with the invention, in order to reduce the risks associated with the projection of carbon dioxide in the corridor 9, the installation 1 comprises an atmosphere control system of the cleaning corridor 9, comprising a detector 15 of carbon dioxide. carbon, adapted to measure the amount of carbon dioxide present in the corridor 9. The control system 15 is preferably installed on a ceiling of the corridor 9. Advantageously, the detector 15 measures the concentration of carbon dioxide in the ambient air 9. Alternatively, the carbon dioxide detector may be adapted to measure any other type of parameter representative of the amount of carbon dioxide present in the corridor 9.
    The control system also includes a carbon dioxide suction system 17.
    The carbon dioxide suction system 17 is, for example, formed between the rails 91 from a central reservation or collector running along the corridor 9 and covered with caillebottis throughout its length. The main function of the suction system 17 is to collect the dirt from the cleaning of the rolling vehicle 100 and also to suck the carbon dioxide emitted by the dry ice blasting. The carbon dioxide suction system 17 is connected by reservations in the concrete to a system 60 for filtering, extracting and discharging at a regulatory and conformal height of the carbon dioxide.
    The control system also includes a ventilation system 19 adapted to inject fresh air into the corridor 9. The ventilation system 19 is preferably installed on a ceiling of the corridor 9.
    The suction system 17 and the ventilation system 19 are adapted to be controlled according to the amount of carbon dioxide measured in the corridor 9 by the detector 15. The installation 1 comprises for this purpose electronic control means 21 The control means 21 may for example be formed by an electronic control unit. On the basis of the measurement of the amount of carbon dioxide carried out by the detector 15, which can for example be transmitted by the detector 15 to the unit 21 in the form of an electrical signal SI 5, the unit 21 determines whether the value detected exceeds a threshold value from which the risks of explosion or intoxication increase. According to this determination, the unit 21 triggers the aspiration of the carbon dioxide contained in the atmosphere of the corridor 9 by the suction system 17, and the blowing of fresh air into the corridor 19 by the ventilation system. ventilation 19. Thus, the amount of carbon dioxide present in the atmosphere of corridor 9 is reduced. The electronic unit 21 may for example communicate with the suction system 17 and the ventilation system 19 by respective electrical signals S17 and S19.
    According to an optional aspect of the invention, the installation 1 comprises an input detector 23 of a vehicle traveling in the corridor 9 adapted to transmit to the unit 21 a signal S23. The detector 23 may be a laser detector or photocells coupled to a beacon receiver. On the basis of this signal, the unit 21 automatically starts the cleaning procedure and transmits to the jets 11 and 13 of the electrical signals S11 and SI 3 for engaging the blast of dry ice.
    Advantageously, the installation 1 comprises a technical room 40 adjacent to the corridor 9. The technical room 40 comprises at least the electronic control means 21, the air dryer compressor 5, the dry ice machine 7 and part of the pipes C1, C2, C3 and C4. Alternatively not shown, the technical room 40 may also include the reservoir 3 for storing carbon dioxide in the liquid state.
    In general, the invention avoids the use of water, which is advantageous for countries in which access to water is limited. It also avoids the construction of a water distribution network and reduces the cost of installation. The non-use of water also prevents the creation of wastewater to be reprocessed. Cleaning does not involve chemicals, carbon dioxide being a naturally occurring molecule in the atmosphere, which is beneficial for countries with stringent environmental policies. The non-use of water and chemicals also avoids the risk of rust on moving vehicles, and produces better cleaning. The invention also makes it possible to simplify the installation with respect to the installations of the prior art, does not require a high maintenance and manufacturing cost. The invention does not involve in particular mechanical cleaning elements such as brushes coming into contact with the rolling stock, which simplifies its design. The invention does not degrade from a total point of view the carbon footprint at the industrial level since the liquid carbon dioxide purchased as a raw material for this installation is intended to be released into the air. At a different location, in a separate industrial process, the carbon dioxide produced has been sequestered, liquefied, and sold for use and disposal elsewhere. The invention applies to all types of railway vehicles, such as wheeled vehicles with wheels or pneumatic wheels, such as trains, subways, trams.
    According to an embodiment not shown, the invention also applies to all other types of vehicles, such as goods transport vehicles or public transport of people.
