Definitions

  • the invention relates to a device for cleaning a flat surface with powerful water jets, in particular for removing rubber from runways, comprising one or more nozzles which are connected by means of a pipe to a source of pressurized water, a circulation system which is movable with the nozzles, said systems being at least provided with a water tank, a pump unit connected thereto for raising the water to high pressure, a hood with suction line fitted around the nozzles, filter means for removing solids from the water extracted from the hood, and a return pipe to the tank.
  • Such a device is know from DE-B-2,617,635.
  • Another known method is to remove the rubber deposit using powerful water jets which are directed at the runway from nozzles at a distance of about 60 cm.
  • the pressure used is, for example, about 400 bars and water consumption is 70 to 100 litres of water per minute.
  • the water polluted with rubber particles goes into the environment, so that this method also is harmful to the environment.
  • Other disadvantages are that water consumption is high and control is so imperfect that there is a great risk of the asphalt surface being damaged.
  • the device disclosed in DE-B-2,617,635 aims to prevent such pollution by removing solids from the water, however, the filtering is not sufficiently effective and therefore there is a risk of clogging of the filter and the risk of solid particles being introduced into the tank.
  • the object of the invention is to avoid these risks and therefore the device is fitted with a cyclone for the extraction of air from the water extracted from the hood, a filter for coarse lumps connected to the cyclone, at least one bag-type filter for particles larger than 3 ⁇ m and an activated carbon filter for small particles.
  • a very high water pressure is used which means a pressure of the order of 1,800 to 2,400 bars.
  • Less than 25 litres per minute is sprayed onto the runway.
  • the re-circulation means that the rubber passes into filters and quite a considerable quantity of the water sprayed onto the runway is returned to the tank.
  • the water consumption is therefore only about one quarter of the water consumption with the water jet method without re-circulation. Since most of the water is removed from the runway, the latter is always available for emergency landings.
  • the tank can be made relatively small and can be carried on a vehicle with the nozzles.
  • the vacuum required to take the polluted water from the nozzle hood to the cyclone and to separate off and remove the air inside the cyclone could be created by a vacuum pump. It is, however, simpler for a cabinet to be placed on the cyclone connected to the inside thereof and having one or more venturi fittings which are connected to an air compressor.
  • a diaphragm pump is preferably provided in the liquid line between the cyclone and the filter bag and in the liquid line between the filter bag and the activated carbon filter.
  • the activated carbon filter has to be cleaned periodically by flushing back.
  • a liquid connection is provided both between the tank and the liquid discharge side of the activated carbon filter and between the liquid infeed side of said filter and the bag-type filter, switchable valves being present in the system to take tank water to the side of the activated carbon filter which is normally the discharge side, for periodic flushing of the activated carbon filter, and for taking flushing water from the normal infeed side of the activated carbon filter to the bag-type filter.
  • the high-pressure pump is designed as an intensifier provided with a hydraulically driven plunger system which converts relatively low pressure and high delivery into very high pressure and low delivery.
  • a high suction output as regards the water in the nozzle hood is achieved if the suction hose opens out tangentially into the hood fitted round the nozzles.
  • a number of nozzles will be disposed on a rotary vertical shaft.
  • the high-pressure pump (intensifier) must be protected from solids being washed out of the tank.
  • a duplex filter is therefore provided in the connection between the water tank and the high-pressure pump.
  • the bag-type filters have to be replaced periodically, and in order to do this without interrupting the working of the device, at least two bag-type filters are disposed in parallel, and valves are present in the pipes to said filters.
  • the device shown is intended for cleaning flat surfaces. Its particular object is to remove rubber deposits caused by aircraft tyres on airport runways. Use is made of powerful water jets which are directed towards the ground at a distance of about 15 cm from the ground.
  • the two nozzles are indicated by 1 in Fig. 4. They are each disposed on the end of a pipe 2 which is connectecd to a central hollow shaft 3, which can be rotated by means of a drive mechanism 4.
  • the nozzles are located in a round hood 5 into which a suction line 6 opens tangentially.
  • Fig. 1 shows schematically the whole device with the pressure generator, filters and recirculation systems. This device is placed on a vehicle which can also carry the hood 5 with nozzles.
  • the filter and recirculation system can be placed on a separate vehicle which follows the vehicle 7 on which the hood 5 is mounted.
  • the suction line 6 of the hood 5 is connected to a suction hose 8 which leads to a cyclone 9.
  • Compressed air produced by a compressor 13 can be conveyed through line 14 to the cabinet 10 opposite the venturi fittings 12, vacuum being created in the top part of the cyclone.
  • the purpose of this vacuum is to carry the soiled water through the hose 8 to the cyclone and in conjunction with the functioning of the cyclone to separate off the soiled water.
  • a diaphragm pump 16 is connected by means of a line 17 to the discharge side and by means of a line 18 to the inlet side of the filter 15.
  • a ball valve 19,20 is provided in each of the lines 17,18.
  • the diaphragm pump 16 is connected to bag-type filters 22 and 23 by means of line 21 and two branches 21 a and 21 b.
  • a valve 24a, 24b is fitted in each of the branches.
  • the soiled water coming from the cyclone is pumped by the pump 16 to one of the bag-type filters 22, 23, in which particles larger than 3 J.Lm are recovered.
  • a line 25 connects the discharge side of the bag-type filters to a diaphragm pump 26, which is connected by means of line 27 to a sand activated carbon filter 28.
  • the discharge side of said filter is connected by means of a line 29 to a water tank 30.
  • the fine particles are removed in the filter 28 from the water from which the coarse material has been removed, and the cleansed water flows back into the tank 30.
  • water flows through pipe 31 to a hydraulically driven variable displacement pump 32 (intensifier) for the generation of ultra-high pressure (for example, 2,200 bars), while a duplex filter 33 is placed in the line 31.
  • a hydraulically driven variable displacement pump 32 intensifier
  • ultra-high pressure for example, 2,200 bars
  • a duplex filter 33 is placed in the line 31.
  • the quantity of water sprayed on the asphalt is about 24.5 litres per minute. Since the water sprayed onto the runway is removed, the runway is always available for emergency landings.
  • the recycling ensures that the tank 30 can be relatively small, and is thus transportable on a vehicle.
  • the sand activated carbon filter has to be flushed clean from time to time.
  • provision is made between the tank 30 and a branch point of the line 25 for a line 35, in which a valve 36 is placed.
  • the flushing system also needs a valve 37 in the line 25, a valve 38 in the line 27, a line 39 connecting the lines 27 and 29 to valve 40, and a line 41 connecting lines 27 and 21 to valve 42, and a valve 43 in the line 29.
  • the filter 28 can be flushed back, water being conveyed to a bag-type filter 22 or 23.
  • valves 24a, 24b In normal operation one of the bag-type filters is always in use. Through operation of the valves 24a, 24b, it is possible to switch over from one bag-type filter to the other, and the used filter can be replaced without the work having to be interrupted.
