Definitions

  • the invention relates to a method for the disposal of the gases released and / or existing when refueling a vehicle with fuel, in particular gasoline-air mixtures, by suction and return to a fuel tank, for example an underground tank, a gas station, and a device for carrying out this method.
  • gas mixtures are formed in the vicinity of the tap, which contain more or less large amounts of gasoline. As a rule, this can also be smelled by the person carrying out the refueling process, so that there are increasing discussions about the harmfulness of the inhalation of such toxic gases and it is also becoming apparent that environmental pollution takes place even when there are non-smellable gas concentrations.
  • the purpose of the invention is to avoid this undesirable and harmful pollution.
  • the invention has for its object to provide a technically simple disposal, avoiding the mentioned disadvantages, which has no undesired air intake, is simple in terms of equipment and requires little space, so that retrofitting of existing petrol stations is also possible.
  • the object is inventively achieved by a method of the aforementioned type characterized in that the suction-flow fuel is carried out of the vehicle during the process of fueling exclusively in that for the extraction a constant negative pressure in the disposal system, regardless of the number of connected fuel dispensing points maintained is that the gases to be disposed of are temporarily stored in the fuel tank, for example an underground tank, and that the gases are preferably disposed of via an activated carbon filter, regardless of the extraction process. This makes it possible to record 90% of the gases produced during the extraction and thus disposal, without unnecessary or unnecessary air being sucked in from the environment, which would be able to burden the disposal system.
  • the suction is preferably carried out with a constant negative pressure between 0.1 and 0.3 bar, preferably 0.2 bar in the disposal system by means of a pump control which reacts to changes in the disposal system which take place as a function of the number of activated tapping points.
  • the device according to the invention for carrying out this method has a gas suction line, which is led from a vacuum pump to the suction point on the one hand and opens into a disposal container, in particular the underground tank, and is characterized by a control valve in the gas suction line, which opens the connection to the vacuum pump as soon and as long Fuel flows through a refueling fuel line, through a pressure sensor connected to the gas extraction line to determine the vacuum and control of the vacuum pump in order to keep the vacuum in the gas extraction line constant, and through a device connected to the disposal container for activated carbon filtering, flaring or the like Gases.
  • control valve can be connected to a fuel flow meter, in particular a piston meter for measuring the fuel quantity of the fuel dispensing line, in order to open or close it.
  • a fuel flow meter in particular a piston meter for measuring the fuel quantity of the fuel dispensing line
  • the degassing device is thus very simple, works only when and as long as fuel is filled into the tank of the motor vehicle and thus detects the harmful gases in the tank for disposal, the degassing caused by turbulence during the filling process, without additional air being sucked in from the environment are and can be easily installed on existing petrol station facilities.
  • branch lines can be connected to the gas suction line according to the number of suction points to provide a central disposal system with a pump and a disposal container, each of which is provided with a control valve which opens the connection to the pump depending on the fuel flow at the respective suction point and closes.
  • the refueling system shown schematically in the drawing consists of an underground tank 1 for the fuel.
  • the further fuel tanks present at each petrol station are not shown in the drawing, since everyone is familiar and familiar with the fact that different underground tanks are available at the usual petrol stations for the different types of fuel.
  • a fuel dispensing line 2 is connected to the underground tank 1, drawn in dash-dotted lines, and leads in a known manner via an associated petrol pump to a fuel nozzle 3 or 4 by means of two branch lines 5 and 6.
  • Each fuel branch line 5, 6 is provided with a gas measuring device 7 or 8, which determines the presence of air in the fuel line and separates it automatically in order to avoid incorrect calculations of the fuel quantity drawn.
  • a piston meter 9 or 10 for fuel quantity measurement in each fuel branch line 5, 6, which is connected to the liter display and the price calculation system of the fuel pump.
  • the piston meter is basically an element of a refueling system, which only starts to work when fuel is removed and stops when the removal process has ended.
  • the tank system described is equipped with a central disposal device for the gases which are released and / or are present when fueling a motor vehicle, in particular gasoline-air mixtures, by suction and return to the underground tank 1.
  • the device consists of a gas suction line 11 or 12 which is led from the nozzle 3 or 4 to the underground tank 1, the two gas suction lines 11 and 12 being brought together at a convenient point, for example via a T-piece, to form a single disposal line 13 .
  • a control valve 14 is located in the gas suction line 11 or 12 or 15 arranged, which receives its switching signal from the associated piston counter 9 or 10.
  • the control valve 14 or 15 opens the connection between the suction point on the nozzle 3 or 4 and a connection to a vacuum pump 16 of the disposal line 13, which in turn is connected to the underground tank 1 via a line.
  • the vacuum pump 1 works continuously and is intended to maintain a constant vacuum of 0.2 bar in the disposal system.
  • the performance of the vacuum pump 16 is regulated by means of a pressure sensor 17, which detects the pressure present in the disposal line 13 and regulates the pump output in the sense of keeping the pressure constant at 0.2 bar in the disposal system.
  • a vent line 18 is also connected to the underground tank 1 and is connected to the atmosphere via an activated carbon filter 19.
  • the branch piece 20 or 21 still to be found in the drawing serves to bring together and later coaxially guide the separate line systems “fuel” / “gas disposal” and thus illustrates the possibility of carrying out the installation of the disposal device on existing tank systems in a simple manner.
  • the vacuum pump 16 uses the pressure sensor 17 to generate a constant pressure in the disposal system of 0.2 bar. If a refueling process is carried out, the fuel nozzle is lifted out of the fuel pump and placed on the tank filler neck of the motor vehicle, a sleeve 22 or 23 being placed over the neck as airtight as possible. As soon as fuel is removed, the control valve 14 or 15 receives a switching signal from the piston counter 9 or 10 - or also mechanically from the fuel nozzle - and is opened. The connection of the suction point 24 or 25 via the Vacuum pump 16 with the underground tank 1 is thus produced and the disposal of the gasoline-air mixtures 1 occurring during refueling is ensured.
  • Disposal takes place only as long as fuel actually flows as part of the refueling process.
  • the piston knife 9 or 10 sends a corresponding switching signal to the control valve 14 or 15, which closes and thus interrupts the connection to the vacuum pump 16. If there is an overload of the underground tank 1 in terms of volume through this disposal, the excess gases are disposed of via the ventilation line 18 and the activated carbon filter 19 in a cleaned manner to the atmosphere.
