Definitions

  • the invention relates to a device for storing technical gases according to the preamble of claim 1 and a method for decanting and storing these gases.
  • gases for example gases in the air such as nitrogen, oxygen, argon etc.
  • gases in the air such as nitrogen, oxygen, argon etc.
  • gases in the air such as nitrogen, oxygen, argon etc.
  • gases in the air such as nitrogen, oxygen, argon etc.
  • the suitable processes and facilities differ essentially in the physical state in which the gas is stored.
  • the containers are generally designed according to the principle of the vacuum-insulated double jacket container.
  • the inner container contains the gas, which is in the liquid and in the gaseous phase. According to the vapor pressure curve of the medium, both phases are in equilibrium with each other.
  • the inner container must be designed for the maximum working pressure inside with a vacuum as external pressure.
  • the inner container is exposed to the storage temperatures of the liquefied gas, i.e. very low temperatures. Therefore, the inner container in the known embodiments made of stainless steel to withstand the loads at these temperatures.
  • Such containers are relatively expensive due to the material costs alone.
  • the larger tanks for liquefied gases are equipped with external evaporators.
  • internal evaporators can also be implemented, which are arranged in the space between the inner and outer containers and, due to the heat removal, increase the insulating effect of the space.
  • small containers are subject to pressure increases and possibly gas losses through the safety valve during long periods of inactivity.
  • the content displays are relatively expensive and inaccurate, the pressure regulating elements are difficult to adjust to the value desired by the consumer and their operation is often too complicated for customers. Small containers are very bad for high fluctuations in consumption.
  • the device according to the invention for storing technical gases has an inner container 1 and an outer container 2.
  • the inner container 1 is arranged within the outer container 2 in such a way that an intermediate space 3 is present between the two containers, which intermediate space is the inner container completely encloses.
  • the inner container is provided in its upper area with a filling line 4 and in its lower area with an extraction line 5.
  • the two lines 4, 5 are each guided through the outer container 2 to the outside.
  • the bushings 6, 7 required for this are designed in such a way that tightness is guaranteed, even when the outer container is under pressure.
  • the storage container is filled with liquefied gas via the connecting line 8 and the shut-off element 10. After filling, the liquefied gas 9 is in the inner container 1.
  • the filling process is ended at the latest when the inner container 1 is completely filled.
  • the differential pressure between the inner container 1 and the intermediate space 3 is used in an embodiment of the method according to the invention. If the differential pressure increases, that is to say the pressure in the inner container increases, this means that the inner container is completely filled with liquefied gas, that is to say the filling process has ended.
  • the outer container 2 is provided with a connection 5b, which is advantageously located in the area of the bushing 7.
  • a device for displaying the differential pressure or for automatically ending the filling process is connected to the connection 5b on the one hand and on the line 8 on the other hand, connected.
  • a closable opening 5c is additionally provided at the lowest point of the outer container 2, that is to say in the area in which the leadthrough 7 is advantageously also located. This opening 5c is used to drain liquid, for example after leak tests have been carried out.
  • Evaporation of liquefied gas in the closed volume increases the pressure in the inner container after filling.
  • the extraction line 5 attached to the nozzle 5a leads through the outer container into the inlet 14 of an evaporator 13 arranged outside the outer container.
  • the evaporator 13 is preferably arranged in the vertical direction.
  • the gas outlet 15 of the evaporator 13 is connected to the gas inlet 16 of the intermediate space 3 via the line 17. The liquefied gas emerging from the inner container thus passes into the evaporator 13 and from there into the intermediate space 3.
  • Gas is withdrawn from the intermediate space 3 by means of a gas line 18.
  • the gas line 18 is connected at the node 18a to the line 17 leading to the intermediate space 3 and to the gas outlet 15 of the evaporator 13.
  • the gas line 18 is equipped with a shut-off device 19.
  • a safety valve 20 which prevents the pressure from rising above the maximum permissible value, for example in the event of the system being overfilled with liquid gas, by releasing gas to the outside.
  • This safety valve is via node 18a and the lines connected there are connected to the intermediate space 3 and the evaporator 13.
  • a hydrostatic pressure which is composed of the vapor pressure in the gas cushion 12 and the static pressure of the liquid column, which is defined by the height of the instantaneous liquid level 11 above the connection 5a, acts on the connection 5a of the extraction line.
  • liquefied gas 9 enters the evaporator 13 through the outlet nozzle 5a and the line 5.
  • the evaporator 13 is preferably a heat exchanger, which uses the environment as a heat source. In the evaporator 13, the liquefied gas absorbs heat from the environment and evaporates. Since the gas has a lower density than the liquid, it rises. It emerges heated at the upper end 15 of the evaporator 13 and reaches the intermediate space 3 via the line 17 and the inlet 16.
  • the pressure in the intermediate space 3 during evaporation and warming up of the liquefied gas quantity 9 is lower by the pressure loss in line 5, in evaporator 13 and in line 17 than in the inner container.
  • the evaporator 13 is installed in a vertical arrangement and the gas inlet 16 into the outer container is preferably at a higher level than the maximum filling level for the liquefied gas.
  • the pressure loss that occurs when flowing through the line 5, the evaporator 13 and the line 17 determines in addition to the pressure drop the flow velocity and thus the mass flow of the transfer process between the inner container and the intermediate space.
  • the heating of the vaporized gas and thus the temperature at which the gas enters the intermediate space at the gas inlet 16 depends, among other things, on this mass flow and the heat flow transmitted by the evaporator.
  • the relevant components are adjusted so that the gas temperature at gas inlet 16 does not fall below the temperature of the surroundings by more than 10 to 20 °. So there is no cryogenic medium in the gap.
  • the outer container must withstand the gas pressure inside it, but it is not exposed to the thermal stress of the frozen liquefied gas. For this reason, it is possible to manufacture the outer container, which has to be dimensioned accordingly, from an ordinary, comparatively inexpensive steel.
  • the gas jacket located in the intermediate space 3 between the inner and outer container completely encloses the inner container 1 and in this way forms an insulator for the inner container 1, which acts as a low-temperature vessel.
  • the inner container which is to be manufactured from relatively expensive material, for example stainless steel, for reasons already mentioned, can thus be kept relatively thin-walled.
  • FIG. 2 shows a second embodiment of the gas container according to the invention.
  • the outer container 21 and the inner container 22 are not cylindrical, but spherical. Otherwise, the structure of this embodiment corresponds to the structure described with reference to FIG. 1.
  • An additional possible application of the invention results if, for example, the spherical container shown in FIG. 2 were mounted on a transport pallet. With the help of standard pallet conveyors, the container could be moved to a location that is easily accessible to the tanker and to various locations.
  • a gas container is created, which represents a very interesting variant for conventional bundles of bottles or small containers for deep-frozen liquefied gases for medium-sized consumers.
  • the outer container of the device according to the invention is constructed as a pressure container and is designed for an internal pressure of, for example, 60 bar.
  • the container according to the invention can be set up at the customer and can be filled with frozen liquefied gas quickly and economically like a conventional low-temperature container by tanker truck or transport container.
  • the evaporator can be designed to be smaller than in the case of conventional low-temperature containers, since the vaporization of the frozen liquefied gas takes place gradually and the intermediate space formed by the outer container acts as a gas reservoir with a relatively large volume.
  • the inner container which is made of expensive material such as stainless steel, only has to be designed for a very low internal pressure.
