Definitions

  • the invention relates to a system for filling gas tanks, such as those used for receiving gaseous fuels for internal combustion engines. It uses at least two pressurized or pressurized gas containers, as gas storage devices, which are connected to a tap or a distributor for several taps via lines of a line system.
  • the gas tank to be filled can also be a conventional portable gas container.
  • the system according to the invention can be used to fill gas tanks on vehicles powered by natural gas, but also for other gaseous fuels, such as Biogas or hydrogen can be used.
  • So-called bank systems have been used to fill gas tanks, among other things.
  • Two or three pressurized or pressurized gas containers are used, in which gas can be stored for different pressure ranges when filling gas tanks.
  • a gas tank (L-bank) for the lower pressure area in the gas tank a gas tank (bank) for the medium pressure area and the third gas tank (H-bank) for the upper pressure area in the gas tank are used in a three-tank system. Since the flow rate and consequently the required filling time of gas tanks, without additional intermediate compression, depends on the respective pressure
  • the difference between the gas storage and the gas tank depends on the bank system, so that at the beginning of the filling process the filling is done first from the L bank, then from the M bank and finally from the H bank.
  • the corresponding gas store can be used until the pressure equalization between the gas stores and the gas tank is reached.
  • An L-bench is not used in two-bank systems.
  • Gas tanks and likewise an at least approximately 100% utilization of the compressed gas contained in gas stores is possible when using dynamic gas stores as described in DE 198 43 669 Cl.
  • the pressure in the gas storage is kept constant by reducing the volume in the gas storage accordingly.
  • the problem is that users require the shortest possible tank times and a maximum filling of the gas tanks, but from the point of view of the system builder / operator, the gas quantity stored in the pressure or pressure gas tanks should be used to the maximum or at the same time.
  • the system according to the invention for filling gas tanks uses at least two pressurized or pressurized gas containers of a conventional type which are connected to a tap or a line via a line system Distributors for several taps are connected.
  • more than two such pressure or pressure gas containers can also be used, with the possibility of bundling them into two units.
  • the pressure or pressure gas containers used represent gas storage devices, in which compressed gas with the same or different maximum pressure can be contained.
  • the gas tank can be filled taking into account the current pressure drop from one or the other gas storage, the compressor arranged in the bypass line acting both as an intermediate amplifier and increasing the pressure when filling the gas tank effect how refilling of at least one of the two gas stores can also be carried out during filling pauses.
  • the solenoid valves connected to the various lines in the line system can be opened or closed as required.
  • sensors and their signals can be used on or in the line system on the various lines can also be switched directly via a programmable logic controller for actuating the solenoid valves. With the sensors, the respective pressure in the lines, but also the current volume flow of the gas flowing into the gas tank, can be measured.
  • the various magnetic valves can also be controlled in a time-controlled manner, in which case the measurements may then be dispensed with.
  • the compressor arranged in the bypass line is advantageously a hydraulically operated double-piston compressor.
  • Such a compressor can be controlled by means of a directional control valve, so that hydraulic fluid is pressed alternately into the two hydraulic cylinders of the double-piston compressor and, by corresponding movement of the double piston, gas is displaced in compressed form from one of two working cylinders and subsequently gas flows into the second working cylinder can.
  • check valves are connected in the connecting lines between the working cylinders of the compressor and the gas storage tanks or to the gas tank.
  • Figure 1 an example of a system according to the invention, in a schematic representation
  • FIG. 2 the schematic structure of a compressor which can be used in a system according to the invention.
  • two gas stores 1 and 8 are connected via lines 23, 24 and 25, which form a valve-controlled line system, to a distributor 15, to which a plurality of tapping points can be connected.
  • the two gas accumulators 1 and 8 can have a different pressure level and consequently can be used in a similar way to a known M bank and H bank.
  • the gas storage device 1 can be supplied with compressed gas via a compressor (not shown) or a mobile system.
  • the gas reservoir 8 can be filled via the compressor 7 from the gas reservoir 1 or also via the compressor, not shown.
  • the solenoid valve 10 is opened and the filling takes place from the gas bank 8 forming the H bank via the lines 24 and 25, with the solenoid valve 14 open further. Since the output pressure in the gas storage device 8 is higher than the current pressure in the gas storage device 1, the usable pressure difference between the gas storage device 8 and the gas tank to be filled is of course larger again, so that the filling takes place in a correspondingly shorter time and leads to a higher filling level can.
  • the filling speed can be increased and consequently the time required for filling can be reduced by closing the solenoid valve 10 and opening the solenoid valve 11 present in the line 28.
  • the gas can then be fed in a third cycle via the bypass line 2, 2 ′ and the compressor 7 through line 25 to the distributor 15.
  • the compressor 7 is switched on and gas can be conveyed to the gas tank at a higher pressure via the distributor 15.
  • the gas store 8 as an H bank
  • the gas store 1 can be refilled from the gas store 1 as an M bank.
  • the solenoid valves 11 and 14 are closed.
  • the gas passes from the gas storage device 1 via the line 23, the compressor 7 that is switched on through the opened solenoid valve 10 and the line 24 into the gas storage device 8.
  • Sensors for example pressure sensors, volume flow sensors or flow rate meters, can be used to control the system.
  • the dashed line 28 with the solenoid valve 11 and the dashed check valve 21 can then be omitted if in a lower Expansion stage of the system on the above 3rd cycle can be dispensed with.
  • a check valve 21 and a second check valve 22 are provided in the line 23 between the bypass line 2 in order to prevent undesired gas flow.
  • the pressure switch 13 switches the system off when the maximum pressure in the gas tank has been reached.
  • control can be programmed or an appropriate control program can be selected so that the filling request is completely covered by the gas storage 8 as an H bank.
  • FIG. 2 shows a compressor 7 that can be used in the system according to the invention, with the elements required for its operation. It is a hydraulically operated double-piston compressor, in which the double piston 3 is driven by hydraulic oil, which is pumped by a hydraulic pump 16 and controlled by means of a directional control valve 6, and can be moved back and forth in translation.
  • the compressor 7 is shown in the rest position.
  • the low leakage in the directional control valve 6 has reduced the hydraulic pressure in the hydraulic cylinders 28, 28 '.
  • valve 29 which is arranged, for example, in the line to the gas pressure accumulator (H bank), is opened and gas can be supplied directly via the check valves 19, 19 'and 20, 20 'flow into the gas tank, which could theoretically take place up to the pressure equalization between gas storage 8 and gas tank.
  • H bank gas pressure accumulator
  • the movement of the double piston bens 3 is supported by the residual gas pressure in the right cylinder 4 ', and consequently the compression work required from the hydraulic side is reduced by the energy stored in the compressed gas.
  • the directional control valve 6 switches to the switching position 31 and hydraulic oil is accordingly conveyed via line B into the right-hand hydraulic cylinder 28 ', so that the Double piston 3 is now moved to the left and the process is now repeated in the opposite direction, the gas contained in the right working cylinder 4 'being compressed and conveyed into the line 18 by the correspondingly arranged check valve 20'.
  • the oscillation process of the double piston is maintained until the pressure switch DS or a pressure sensor on the gas reservoir 8 or on the gas tank or its tap reaches the desired pressure in the gas tank or in the gas reservoir 8 reports.
  • the hydraulic system is switched off by switching off the hydraulic pump 16 and de-energizing the directional control valve 6, the double piston 3 again moving into the middle position shown.
  • a high volume flow can be achieved at low gas pressure in the gas store 8 or in the gas tank.
  • the noise level can be kept low by choosing appropriate valves.
  • the directional control valve 6 can be used in a so-called "soft shift" version. As a result, the switching movements of the directional control valve 6 can be delayed and switching shocks and pressure peaks can be effectively avoided.
  • the switching behavior can be optimized by means of corresponding switching amplifiers in the valve plugs, so that the compressor 7 can be operated with low noise.
  • a power-controlled hydraulic pump 16 has been used, in which, based on the drive power of the drive motor of the hydraulic pump, the product of volume flow and operating pressure can automatically be kept constant.
  • the required volume flow of the hydraulic pump can thus be regulated to a maximum value as long as the pressure on the gas outlet side is still relatively low and the compressor 7 oscillates with ⁇ H oo L ⁇
