Description

The DME fuel filling system
Technical field
The present invention relates to a kind of DME fuel filling system that is used at the tanks filling DME fuel of storing DME fuel.
Background technology
For example, in recent years,, be that purpose uses the vehicle of liquefied gas as fuel that the tendency of increase is arranged with low public hazards along with the strictness control of the exhaust emission of vehicles such as automobile.As this liquefied gas as fuel, general known to all is autogas (below, be called LPG) fuel, but the diesel oil of diesel motor is also paid close attention to dimethyl ether (below, be called DME) fuel as an alternative.This DME fuel, diesel oil has the advantage that the discharge rate that can make PM or NOx becomes few relatively, also expects very high as low public hazards countermeasure.
But, store in the tanks of above-mentioned LPG fuel or DME fuel, all know the maximum charging quantity of having stipulated to be filled in the fuel in the tanks, and know to be equipped with and be used for the formation that filling is no more than the anti-locking apparatus of over packing of this maximum charging quantity.As the anti-locking apparatus of this over packing, for example, shown in patent documentation 1, suggestion be equipped with along with being stored in level of fuel height in the tanks unsteady buoy, with buoy link cam mechanism and open and close the open and close valve that in tanks, flows into the inflow entrance of fuel by cam mechanism, be set at the electrolyte level position that reaches the maximum charging quantity of tanks as this buoy, just thereby open and close valve is closed the filling that inflow entrance forces to stop fuel.
In addition, for example, in patent documentation 2, advise a kind of system that is used at storage facilities filling LPG fuel.This formation, be when filling LPG fuel, measure the charging quantity that is filled in the LPG fuel in the storage facilities, it is set at as reaching the charging quantity of regulation, just change the filling velocity of LPG fuel, the filling incipient stage with the low speed filling, set at high speed filling till the liquid measure to the 1st, set liquid measure to the 2 from the 1st and set till the liquid measures, set the liquid measure filling the 2nd and stop with the low speed filling.By changing the filling velocity of LPG fuel, can prevent to stop suddenly the filling of LPG fuel like this.Thus, can lower since suddenly filling stop the water hammer action (water hammer water-hammering) to be taken place, thereby can prevent pump, pipe arrangement, the anti-locking apparatus of over packing etc. produces undue load.

[patent documentation 2] TOHKEMY 2003-148690 communique
But above-mentioned DME fuel because of its energy density is lower than diesel oil, when being applied to automobile, tends to increase the capacity of tanks in order to obtain sufficient operating range.Same loading time when reaching with diesel oil for the loading time of wanting that makes filling DME fuel in high-capacity tanks like this requires this DME fuel of high speed filling.But, the pressure that produces by above-mentioned water hammer action, in theory, because of strengthening pro rata, so because the water hammer action that the high speed along with filling velocity strengthens, to pump, pipe arrangement, over packing prevents that locking apparatus etc. brings powerful load with filling velocity.Therefore, during DME fuel, when requiring the filling velocity high speed, also require fully to lower the powerful water hammer action that produces along with this high speed.
And, be applied to the filling of DME fuel by the formation of above-mentioned previous patent document 2, can suppress water hammer action.But, when DME fuel, as described above because of requiring to make the filling velocity high speed, so along with making this filling velocity high speed, and the velocity contrast that can fully lower between the low speed filling velocity of water hammer action becomes big.Therefore, when at a high speed being transformed into low speed, along with velocity contrast becomes greatly problem with regard to the bigger water hammer action of easy generation.And the DME tanks is during than larger capacity as described above, and from being transformed into low-tach time point at a high speed, the liquid measure till maximum charging quantity filling becomes many with filling velocity.Therefore, the liquid measure till the so far maximum charging quantity, as with the low speed filling, this filling wants the time elongated, so the attenuating effect of fuel filling time produces boundary usually.Its capacity along with tanks becomes big and becomes obvious.Therefore, can not fully reach the shorteningization of the desired loading time of DME fuel.
Summary of the invention
The present invention as the system that is used at tanks filling DME fuel, advises a kind of DME fuel filling system that can shorten loading time by higher speed filling, can suppress water hammer action simultaneously.
The present invention, it is to be used in the tanks of storing DME fuel the DME fuel filling system of DME fuel filling till the maximum charging quantity that sets in advance, it is characterized in that, the testing agency of detecting the electrolyte level that is stored in the DME fuel in the tanks and the container identification mechanism of annotating relevant fuel tank container shapes of containers information are set, simultaneously in tanks; Possess the fuel filling control setup is arranged, this fuel filling control setup possesses: the detachable filling ozzle of installing at the filling valve of tanks and being used for by the fuel filling machine of filling ozzle force feed DME fuel to tanks, the information of container that is used for obtaining from the container identification mechanism information of container is obtained mechanism, obtain the electrolyte level of the electrolyte level information that is detected by electrolyte level testing agency and obtain mechanism, with the filling velocity control mechanism, this filling velocity control mechanism is by based on obtain the information of container that mechanism obtains according to information of container, set gauge electrolyte level and the deceleration electrolyte level that is lower than this gauge electrolyte level position, control liquid measure till calculating from this deceleration electrolyte level to the gauge electrolyte level again, obtain mechanism by electrolyte level and obtain electrolyte level information, arrive till the deceleration electrolyte level, come drive controlling fuel filling machine with the high speed filling velocity filling that sets in advance, as reach the deceleration electrolyte level, till reaching the gauge electrolyte level, based on the control liquid measure, come drive controlling fuel filling machine to slow down from the high speed filling velocity.
At this, the tanks of DME fuel, when for example being equipped on automobile, from miniature car to coach or truck, therefore its vehicle dimension wide range sets the different container shapes of size shape to cooperate each vehicle dimension.And, container shapes such as difference, the relation between the liquid measure of being stored and its electrolyte level is also different separately separately.Therefore, even it doesn't matter for the filling velocity of setting fuel and container shapes, in all container shapes, can not obtain the shorteningization of the desired loading time of fuel filling or the attenuating effect of water hammer action.Especially the tanks of DME fuel, as described above, because of the tanks than diesel oil is tended to high capacity, so for the more difficult performance loading time shorteningization of container shapes of each tanks or the attenuating effect of water hammer action.The present invention even in the tanks of such a various container shapes, also can reach the attenuating of above-mentioned water hammer action or the shorteningization of loading time.
In the formation of the present invention, set the container identification mechanism of the information of container of its container shapes of filling expression in each tanks, during filling fuel, read information of container from this container identification mechanism, and according to this information of container, the filling velocity of the container shapes adjusting control fuel of corresponding each tanks.At this, the gauge electrolyte level, the deceleration electrolyte level, the control liquid measure, the container shapes of based on fuel jar and obtaining from the control that the high speed filling velocity slows down, is carried out based on the control liquid measure.Just, the filling velocity from the deceleration electrolyte level to the gauge electrolyte level, corresponding container shapes and controlling.
Because of constituting by it, till the maximum charging quantity that reaches the tanks defined, the filling velocity that can fully slow down is controlled, so even stop fuel filling suddenly when reaching this maximum charging quantity, the water hammer action that takes place in the time of also can suppressing this and stop.And because of the control of carrying out based on control liquid measure (container shapes) slowing down from the high speed filling velocity, the velocity contrast when this slows down fully diminishes, so also can suppress the water hammer action that takes place when filling velocity slows down.Thus, because of even the high speed filling velocity till the near deceleration electrolyte level is set at than higher speed, during the deceleration that also can fully lower filling velocity or the water hammer action that takes place when stopping of filling, so can suppress because this water hammer action is given pump, pipe arrangement, the load that the anti-locking apparatus of over packing etc. brings, thus can bring into play required durability.
And, till the electrolyte level that slows down, by the filling of high speed filling velocity, thereafter, because of the control liquid measure with corresponding container shapes is slowed down, so even in the more high-capacity tanks of storing DME fuel, also can shorten the desired time of fuel filling as much as possible.And, as the high speed filling velocity, in order to become and the same level of the loading time of diesel oil, and be purpose with the loading time of abundant shortening DME fuel, be set more than the filling velocity of diesel oil.
As action effect that suppresses above-mentioned water hammer action and the action effect of shortening fuel filling time, because of corresponding container shapes after reaching the deceleration electrolyte level is carried out deceleration control, so, also can play effect same even in the tanks of various container shapes.And, as the tanks of DME fuel, in tanks, significantly bring into play action effect of the present invention than in the past diesel oil fuel jar high capacity.
And, in this formation, as the gauge electrolyte level that sets by the filling velocity control mechanism, also can be set at the same height and position of electrolyte level with the maximum charging quantity of each tanks defined, also can be set at the electrolyte level position that is below or above maximum charging quantity.And,, be set at and be lower than the electrolyte level position that reaches maximum charging quantity at the deceleration electrolyte level.
And the information of container as the container identification mechanism is annotated can adopt the Article Number that can assert container types or shape, or is used to necessary main dimension of assert container shapes etc.Have again, also can with expression by container shapes the function that concerns between fixed storage capacity and the liquid level, or its constant value filling of the function that concerns between expression filling flow fuel and the electrolyte level etc. is information of container.
In the above-mentioned DME fuel filling system, the filling velocity control mechanism of fuel filling control setup, advise a kind of will the setting according to the deceleration function from deceleration liquid level high speed to the filling velocity that slows down between the gauge electrolyte level, as reach the deceleration electrolyte level, come the formation of drive controlling fuel filling machine according to the deceleration function to slow down from the high speed filling velocity.
During it constitutes, carry out from the deceleration control of high speed filling velocity according to the deceleration function of setting based on container shapes.At this, the deceleration function for example, can be set at the represented function of relation according to filling velocity and electrolyte level (storage capacity).Just, according to the electrolyte level that increases with filling, the control of the filling velocity that slows down.Filling velocity by the water hammer action when can fully lower the maximum charging quantity that reaches tanks, and can shorten as far as possible and reach this deceleration function that maximum charging quantity will be set the time, can stablize action effect that performance suppresses above-mentioned water hammer action and the action effect that shortens the fuel filling time.
In the above-mentioned DME fuel filling system, the filling velocity control mechanism of fuel filling control setup, advise a kind of as reaching the deceleration electrolyte level, to reach the low speed filling velocity that the regulation of water hammer action does not take place at the gauge electrolyte level, slow down from the high speed filling velocity and carry out the formation of drive controlling fuel filling machine.
At this, the so-called water hammer action that do not take place in this formation is meant when stopping fuel mobile, is not only that water hammer action does not take place, and also comprises very little water hammer action and does not take place.Just, even when small water hammer action takes place,, be also contained in the situation of the water hammer action that this formation does not take place as in not influencing the relevant scope of system of the present invention.
To reach the low speed filling velocity that water hammer action does not take place at the gauge electrolyte level,, can suitably bring into play the action effect of the attenuating water hammer action of the invention described above like this by reducing from the high speed filling velocity.And, the gauge electrolyte level is set at electrolyte level with the maximum charging quantity of tanks when identical, or when being set at the electrolyte level position that is lower than maximum charging quantity, even force to stop fuel filling suddenly when reaching maximum charging quantity, water hammer action does not take place yet.And,, at the electrolyte level of maximum charging quantity, can fully restrain the filling velocity of water hammer action, so can lower the water hammer action that takes place when filling stops because of being decelerated to even when the gauge electrolyte level is set at the position that is higher than maximum charging quantity.
And, in the above-mentioned DME fuel filling system, that is advised constitutes: the filling velocity control mechanism of fuel filling control setup, as reach the deceleration electrolyte level, so that the fuel filling machine stops to carry out the drive controlling of slowing down from the high speed filling velocity in the filling of gauge electrolyte level.
During it constitutes, just stop because of being set at as reaching the filling of gauge electrolyte level, so this gauge electrolyte level must be set at more than the electrolyte level of maximum charging quantity.For example, the gauge electrolyte level is set at the electrolyte level of maximum charging quantity, as fuel filling to maximum charging quantity, by the filling velocity control mechanism, can carry out the control that this filling stops, at this moment, can carry out filling by drive controlling fuel filling machine and be no more than maximum charging quantity.
And, in this formation, can be at the gauge electrolyte level, reach zero with filling velocity and carry out deceleration control, the state that also can be decelerated to till the filling velocity of regulation drives the control that stops to the fuel filling machine.
In the above-mentioned DME fuel filling system, that is advised constitutes: set electrolyte level testing agency possesses the unsteady buoy of liquid level of the DME fuel in the tanks of being stored in the tanks, with in reaching this tanks carry out ON action (ON Action) according to buoy during predefined deceleration electrolyte level the decelerate position switch, the electrolyte level of fuel filling control setup is obtained mechanism, ON action according to the decelerate position switch obtains as electrolyte level information with the situation that reaches the deceleration electrolyte level.

And the electrolyte level of the filling control setup that acts as a fuel is obtained mechanism, can be the formation that obtains according to the electric signal of the ON of decelerate position switch action.For example, can be with tanks in the formation of wired formula of the set detachable installation of electrolyte level testing agency, or can be formation by the wireless wireless type of receiving and dispatching the aforementioned electric signal etc.
In the above-mentioned formation, that is advised constitutes: when set electrolyte level testing agency possesses the maximum charging quantity that sets in the tanks in reaching this tanks according to buoy and the maximum position switch of ON action, the filling velocity control mechanism of fuel filling control setup, when the electrolyte level information of the ON action that obtains the maximum position switch, fuel filling is driven the control that stops.
During it constitutes, be directly to detect the electrolyte level that reaches maximum charging quantity, can be rapidly and correctly detect the actual situation that reaches maximum charging quantity.And maximum position switch such as ON move, just by the filling velocity control mechanism to the fuel filling machine drive stop control.Thus, can be at maximum charging quantity correct and stable and filling stop, and can prevent definitely that filling is no more than this maximum charging quantity.
And, in this formation, for example, do not set the anti-locking apparatus of the above-mentioned over packing that in the past constituted, also can make filling be no more than maximum charging quantity.
And, in the above-mentioned DME fuel filling system, that is advised constitutes: by the gauge electrolyte level that the filling velocity control mechanism sets, can be set at as reaching the maximum charging quantity that sets in the tanks prevents device action for the over packing that filling set that stops DME fuel height and position.
During it constitutes, prevent locking apparatus for possessing over packing, and be the formation that the gauge electrolyte level is set at the electrolyte level that reaches maximum charging quantity.As described above, to slow down from highly filled speed and to control, institute is so that the filling velocity that can fully slow down till this gauge electrolyte level till the gauge electrolyte level.For this reason, even suddenly and when forcing filling to stop, also can suppressing the water hammer action that is taken place this moment by the anti-locking apparatus of over packing when reaching maximum charging quantity.Thereby, can suitably play the inhibition water hammer action of the invention described above and bring into play the action effect of required durability.
In the above-mentioned DME fuel filling system, set container identification mechanism in the suggestion tanks, bar code by the filling information of container is constituted, and the information of container of fuel filling control setup is obtained mechanism simultaneously, is made of the apparatus for reading of bar code that reads information of container from bar code.
During it constituted, before the filling of DME fuel began, by the bar code that the jar surface of using apparatus for reading of bar code to read tanks is set, the filling velocity control setup of fuel filling control setup can be easily and is correctly obtained its information of container.Thus, can stablize and carry out exactly based on the setting of the information of container of each tanks and handle, computing, drive controlling processing etc., thus suitably play the action effect of the invention described above.

And, from this deceleration electrolyte level W to gauge electrolyte level T till, as shown in Figure 5, because of with filling velocity S filling, so as mentioned above, the desired loading time of maximum charging quantity is shortened as far as possible according to deceleration function k (h).And, begin till the deceleration electrolyte level W from the filling of DME fuel, comparing during with common LPG fuel is to be set at the filling of high-revolving regulation high speed filling velocity, so usually can shorten from filling and begin the loading time that stops to filling, thereby can be with the time filling DME fuel of relatively lacking.Like this, even when the tanks 5 that DME fuel is used is set at bigger capacity, also can be with the time filling of abundant weak point.
Certainly, even except the container capacity of tanks 5 is 135 liters regulation shape, by information of container from various tanks 5 container shapes of bar code 7 reading displayed, also filling DME fuel equally.For example, even above-mentioned 91 liters, also each coefficient and the capacity of determining to show the cubic function that concerns between charging quantity and the electrolyte level can be set at information of container, and based on this information of container, by implementing and the same speed adjusting control of Fig. 5, play and 135 liters of the same action effects.
Like this, in the formation of present embodiment 1, till the electrolyte level W that slows down (pack completeness 75%), be high speed filling velocity filling DME fuel with regulation, till from deceleration electrolyte level W to gauge electrolyte level T (pack completeness 87%), be according to the deceleration function k (h) that sets based on information of container Yi Bian Yi Bian the filling velocity S filling of slowing down gradually.Thus, can fully suppress since when reaching the maximum fluid height P (pack completeness 85%) of maximum charging quantity filling stop the water hammer action to be taken place, the water hammer action that takes place in the time of also fully lowering filling velocity S low speed simultaneously.Therefore, can prevent anti-locking apparatus 30 of over packing or the mobile generation excessive loads such as pipe arrangement of DME fuel, and can bring into play required durability.And, the loading time of maximum charging quantity is shortened as far as possible, even in more high-capacity tanks 5, also can the high speed filling.
Also have, because of can be as mentioned above high speed filling DME fuel like that, so even to compare with the diesel oil fuel jar be high-capacity tanks 5, also can with the loading time filling DME fuel of the same degree of diesel oil.And, because of slowing down, so, also can fully suppress water hammer action even the high speed filling velocity of DME fuel is set at speed than the high several times of filling velocity of above-mentioned general LPG fuel according to deceleration function k (h).
