Definitions

  • the invention relates to a storage system, in particular for the storage of a cryogenic medium, according to the preamble of claim 1.
  • the invention further relates to the use of a generic storage system for vehicles of all kinds.
  • cryogenic media are prefixed or used in the designations of special cryogenic media according to their state of aggregation; So z. B. GH 2 or LH 2 for gaseous or liquid hydrogen.
  • CNG and “LNG” are used for compressed and liquefied natural gas, respectively.
  • cryogenic media is to be understood below also compressed and liquefied natural gas.
  • the storage of hydrogen or natural gas "on board" the above-mentioned means of transport is most useful in liquid form.
  • the hydrogen and LNG must be cooled to about 25 K and 112 K and held at this temperature - which can only be realized by appropriate insulation measures on the storage tanks or tanks -, but is a storage in the gaseous state due to the low Density of GH 2 and CNG usually in the above means of transport unfavorable, since the storage must be done here in large-volume and heavy storage containers at high pressures.
  • the above-described storage of cryogenic media poses two fundamental problems.
  • the first problem relates to the shape of the storage container, which must be either round or cylindrical shaped due to the required pressure resistance.
  • the working pressure of a motor vehicle storage system is, for example, 2 to 3 bar, the storage container is to be designed for at least 5 to 6 bar, so that - and this will be discussed in more detail below - an acceptable service life can be achieved.
  • the previously realized construction methods of the storage container for cryogenic media do not meet the requirements of the automotive industry, which requires or favors in particular flatter Speicher practicer- or tank shapes due to the specified installation options.
  • the second problem already mentioned concerns the topic of long-term storage. Even if the cryogenic storage container has a so-called superinsulation, it can not be prevented that a small amount of residual heat flow remains in the stored medium; this has the consequence that there is a slow increase in pressure in the stored cryogenic medium and thus in the storage container, so evaporates a portion of the liquid medium. If no removal of cryogenic medium from the storage container takes place over an extended period of time, the pressure continues to rise, with the result that upon reaching a certain pressure threshold value-on which the storage container is designed-a blow-off of the gaseous medium formed in the interior of the storage container is required becomes. This part of the cryogenic medium is usually regarded as a loss.
  • Object of the present invention is to provide a memory system, in particular for the storage of a cryogenic medium, which allows the realization of a comparison with the prior art simpler start-up procedure.
  • a generic storage system which is characterized in that the storage container and the pressure storage container via a cryocompressor line are connected to each other or connectable.
  • the storage system according to the invention can now on devices for increasing the pressure - this example, electric heaters were used - as they previously had to be provided in the storage tanks, are dispensed with.
  • the accumulator tank is now fluidly connected via a line bypassing the cryocooler with the storage tank.
  • the compressed medium flowing from the pressure storage container into the storage container leads to a sufficient pressure increase in the storage container, so that it is ensured that the cryocompressor is supplied with liquid exclusively in the starting mode.
  • the cryocooler is designed for compression to a pressure of at least 100 bar, preferably at least 500 bar.
  • hydrogen is compressed to 100 bar into a line with inlet valves (common rail) connected in parallel.
  • the pressure generation by the cryocompressor and the fuel injection are separated from each other.
  • the injection pressure is generated independently of the engine speed and the injection quantity by the cryocompressor.
  • the figure shows a storage system consisting of a first storage tank S1, which is associated with a supply line 1, via which the medium to be stored is supplied to it.
  • the storage tank S1 further comprises a discharge line 2, in which a not shown in the figure safety valve is arranged; this opens on reaching a preset pressure threshold, the line 2.
  • a bypass line also not shown in the figure is usually provided, which is connected upstream of the safety valve and arranged fluidically parallel to this. This overflow line is set to a lower pressure than the safety valve.
  • liquid medium is withdrawn from the storage container S1 with open valves a and b, compressed in the cryocooler K to the desired pressure and then the consumer not shown in the figure - for example a (modified ) Internal combustion engine or a fuel cell - supplied.
  • a gas extraction line 7, 8 and 9 is provided, which is fluidically connected to the input of the cryocooler K.
  • gaseous medium can be removed and fed to a consumer after compression in the cryocooler K.
  • the removal of Gaseous medium from the storage tank S1 via the gas extraction line (s) 7, 8 and 9 is particularly useful if either the consumer only requires a small mass flow of the stored medium or - for example, after a longer life - already to a significant increase in pressure the storage container S1 has come.
  • a pressure storage tank S2 is provided, which is connected via the lines 11 and 10, in which a valve d is arranged, with the pressure side of the cryocooler K or connectable. Furthermore, the two storage containers S1 and S2 are connected to each other via the lines 7, 13 and 12 or connectable.
  • This accumulator tank S2 can be formed for example by one or more compressed gas cylinders; Conventional compressed gas cylinders are designed today up to 300 bar. But also ultra-high pressure composite containers for pressures up to 1000 bar and more are suitable as accumulator tanks.
  • cryocooler K is driven hydraulically, since this is in addition to economic advantages, especially for reasons of space advantage.
  • the resulting in the storage tank S1 gaseous medium must therefore no longer be discharged via the discharge line 2 to the atmosphere, but can be cached in the pressure storage container S2.
  • cryocooler K is preferably operatively connected to a pressure control which controls the compression of the via the gas extraction line (s) 7, 8 and 9 from the storage tank S1 effluent medium regulates.
  • valves c and d are opened so that gaseous medium can be fed to the cryocooler K, compressed in it and subsequently fed into the pressure storage tank S2.
  • the accumulator tank S2 can now serve as a reserve tank from which, if the consumer over a longer period no medium was supplied and the storage tank S1 is emptied, a supply of the required medium until the next refueling operation takes place.
  • the pressure storage container S2 is switched on and deducted from it for a transitional period, the required residual amount and supplied to the consumer.
  • cryocooler K can also be "supplied" during the starting process - in addition to liquid - with gaseous medium.
  • any desired shape for the storage container can be selected.
  • a reduction in the accumulator pressure also has the advantage that the amount of storage can be increased since the medium to be stored has a higher density at lower pressure.
  • the storage system according to the invention can be used for a large number of different media, but in particular for the storage of LH 2 , LNG, LN 2 , etc.
  • LH 2 low-density liquid crystal display
  • LNG low-density liquid crystal display
  • LN 2 low-density liquid crystal display
