Description
Vorrichtung zum Betrieb einer TankanlageDevice for operating a tank system
Die vorliegende Erfindung betrifft eine Vorrichtung zum Betrieb einer Tankanlage nach dem Gattungsbegriff des-Patefl^nspruches 1.The present invention relates to a device for operating a tank system according to the generic term of patent claim 1.
Zur Rückgewinnung von Benzoldämpfen beim Tankvorgang und zur Schonung der Umwelt ist es bekannt und teils auch durch behördliche Auflagen vorgeschrieben, neben einer Fülleitung für den Kraftstoff zusätzlicheine Absaugleitung für den sich über dem Kraftstoff in dem Fahrzeugtank bildenden Dampf, vornehmlich Benzol, vorzusehen. Eine saugende Rückführeinrichtung in der Absaugleitung wird hierbei hinsichtlich ihrer Saugleistung durch die Abgabemenge des Kraftstoffes gesteuert. In Ländern mit strengen Umweltauflagen wird eine derartige Steuerung der Saugleistung alleine in Abhängigkeit von der Abgabemenge den gestellten Anforderungen nicht gerecht.In order to recover benzene vapors during the refueling process and to protect the environment, it is known and sometimes even required by official regulations to provide, in addition to a filling line for the fuel, an additional suction line for the vapor that forms above the fuel in the vehicle tank, primarily benzene. A suction return device in the suction line is controlled in terms of its suction power by the amount of fuel delivered. In countries with strict environmental regulations, such control of the suction power solely based on the amount delivered does not meet the requirements.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Betrieb einer Tankanlage anzugeben, die den gestellten Anforderungen sehr viel besser gerecht wird.It is therefore the object of the present invention to provide a device for operating a tank system which meets the requirements much better.
Die Lösung dieser Aufgabe gelingt gemäß den kennzeichnenden Merkmalen des Patentanspruches 1. Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind den abhängigen Ansprüchen entnehmbar.This object is achieved according to the characterizing features of patent claim 1. Further advantageous embodiments of the device according to the invention can be found in the dependent claims.
Anhand der Figuren der beiliegenden Zeichnung sei im folgenden die Vorrichtung gemäß der Erfindung näher beschrieben. Es zeigen:The device according to the invention is described in more detail below with reference to the figures in the accompanying drawing. They show:
Figur 1 eine Prinzipskizze einer bekannten Tankanlage; undFigure 1 is a schematic diagram of a known tank system; and
Figur 2 eine Modifikation dieser Anlage gemäß der Erfindung.Figure 2 shows a modification of this system according to the invention.
Gemäß Figur 1 fördert eine Pumpe 12 aus einem Vorratstank 10 Kraftstoff über eine Fülleitung 14 zu einer Zapfpistole 16, wenn diese betätigt wird. Mit der Zapfsäule 16 wird ein Ventil 18 in einer nicht dargestellten Zapfsäule betätigt, das den Durchtritt von der Pumpe 12 zu der Zapfpistole 16 freigibt. Der Kraftstoff fließt hierbei über eineAccording to Figure 1, a pump 12 delivers fuel from a storage tank 10 via a filling line 14 to a fuel pump 16 when the latter is activated. The fuel pump 16 activates a valve 18 in a fuel pump (not shown), which opens the passage from the pump 12 to the fuel pump 16. The fuel flows via a
Luftabscheidevorrichtung und einen Durchflußmengenmesser 20, die beide als ein Block dargestellt sind. Gegebenenfalls ist in der Fülleitung noch eine Fließanzeige 22, beispielsweise in Form eines Schauglases vorgesehen.Air separator and a flow meter 20, both of which are shown as a block. If necessary, a flow indicator 22, for example in the form of a sight glass, is also provided in the filling line.
Der Block 20 wirkt mit seinem Durchflußmengenmesser auf eine Dampf-Rückführeinrichtung in einer Absaugleitung 26, wobei ein Ventil oder eine Saugpumpe im Durchtrittsquerschnitt oder der Saugleistung entsprechend der gemessenen Durchflußmenge des Kraftstoffes gesteuert wird.The block 20 acts with its flow meter on a vapor return device in a suction line 26, whereby a valve or a suction pump is controlled in the passage cross-section or the suction power according to the measured flow rate of the fuel.
Gemäß Figur 2 ist nunmehr erfindungsgemäß vorgesehen, daß die in dem Block 20 gemessene Durchflußmenge FM des Kraftstoffes nur eine Führungsgröße für die Rückführeinrichtung 24' vorgibt, die durch andere Meßgrößen wie die Temperatur T, den Druck P und die Gas-Fließmenge Φ eine Veränderung erfahren kann. Diese Meßgrößen werden durch entsprechende Sensoren in der Absaugleitung gemessen, was durch den Block 28 veranschaulicht ist. Dabei können eine oder mehrere Meßgrößen zur Einwirkung auf die Führungsgröße herangezogen werden.According to Figure 2, the invention now provides that the fuel flow rate FM measured in block 20 only specifies a reference variable for the return device 24', which can be changed by other measured variables such as the temperature T, the pressure P and the gas flow rate Φ. These measured variables are measured by corresponding sensors in the suction line, which is illustrated by block 28. One or more measured variables can be used to influence the reference variable.
Die Rückführeinrichtung 24' für die Kraftstoff-Dämpfe, vornehmlich Benzol, besteht in einer ersten Ausführungsform aus einem regelbaren Proportionalventil 30, das in Reihe zu einer mit konstanter Saugleistung betriebenen Saugpumpe 32 betrieben wird, wobei zwischen beiden vorzugsweise noch ein Abschaltventil 34 angeordnet ist.The return device 24' for the fuel vapors, primarily benzene, consists in a first embodiment of a controllable proportional valve 30, which is operated in series with a suction pump 32 operated with a constant suction power, with a shut-off valve 34 preferably being arranged between the two.
In einer zweiten Ausführungsform umfaßt die Rückführeinrichtung 24' eine regelbare Saugpumpe 30', die in Reihe zu einem Abschaltventil 32' geschaltet ist. 25 In a second embodiment, the return device 24' comprises a controllable suction pump 30', which is connected in series with a shut-off valve 32'. 25
Ein Regler 36 verknüpft hierbei die Führungsgröße FM mit wenigstens einer von den weiteren Meßgrößen T, P, Φ gemäß einer vorgebbaren Regelkennlinie.A controller 36 links the reference variable FM with at least one of the other measured variables T, P, Φ according to a predeterminable control characteristic.
