Definitions

  • the invention relates to a device for providing a gas, which is stored in containers in liquid form or together with a solvent distributed in a porous mass under pressure, each container being provided with a gas filling and gas extraction device, a heating device being provided and wherein the containers are installed in a capsule that is closed on all sides and as airtight as possible.
  • Such a device is described in DE-A-26 50 880.
  • the containers are set up in transport containers or in local spaces and are heated in order to guarantee a certain amount of gas stored per unit of time. From the point of view of extensive emptying of the containers and the guarantee of a certain withdrawal quantity per unit of time, the highest possible temperature is desirable. However, heating the containers to a relatively high temperature leads to high energy consumption combined with considerable heating costs.
  • the invention is therefore based on the object of specifying a device of the type mentioned at the outset which causes only low heating costs, but which does not impair extensive emptying of the containers and which also guarantees a certain removal quantity per unit of time.
  • this object is achieved in that only the gas-tight housing of the containers and the heating device are located inside the capsule, so that the interior of the capsule is minimal, while the gas filling and gas extraction devices are arranged in the ventilated outer space of the capsule.
  • the containers in which gas is stored under pressure together with a solvent distributed in a porous mass or in which the gas is stored in liquid form are enclosed in a capsule before the gas withdrawal, through which two zones are formed.
  • the first zone the interior of the capsule, there are only the parts of the container in whose area there are no leaks, i.e. Gas leaks can occur.
  • the gas-tight part of a container is the container housing with the exception of the gas extraction or gas filling point.
  • This area of each container is in the second zone outside the capsule (zone 11). All containers can be installed in one capsule or some of the containers in one capsule. After the containers have been installed in one or more capsules in this way, gas can be removed from the containers.
  • the interior of the capsule is heated while the exterior is being ventilated.
  • Zone I it is only necessary to heat Zone I for gas extraction. In contrast to the known methods, this zone no longer needs to be ventilated, since within this zone there are no detachable connections, i.e. there are no hoses, fittings and lines in the area where leaks can occur. Since, according to the invention, it is unnecessary to change heated air, the energy contribution specified in point 3, which is a significant heating cost factor, is reduced to a minimum. If the containers can be encapsulated as airtight as possible, the heat loss due to air exchange can be completely eliminated.
  • the volume to be heated according to the invention i.e. the capsule interior, comparatively small. Therefore, the surface of the heated room (the capsule) is smaller than before, which means that the heat losses mentioned under point 2 over the walls of the heated room can be reduced. These losses can also be largely eliminated by using a capsule whose wall is coated with heat-insulating material or which consists of such a material.
  • the containers it is possible to set up the containers installed in a capsule outdoors or in a room.
  • gas When gas is extracted outdoors, it would be important to insulate the entire capsule from the point of view of minimizing heat loss through heat conduction.
  • the containers are accommodated in a room, for example in a mobile container, it is only necessary to provide the parts of the capsule which are on an outer wall of the room with a good heat-insulating material, while the insulating capacity of the Walls facing inside the room may be less.
  • the parts of the container or of the removal device are located in zone H, in the area of which leaks can occur. This zone is therefore ventilated. However, it is not necessary to heat Zone II, so that no heating energy is lost.
  • the heating costs can be reduced to a fraction of the previously incurred costs.
  • the bottles When filling acetylene bottles e.g. the bottles are cooled with cooling water during the filling process.
  • the encapsulation makes it possible to bring the cooling water to the bottles more effectively than before.
  • the separation ensures that the pipes do not come into contact with water and thus corrosion is not promoted.
  • all of the containers combined into a bundle unit via a common removal line are advantageously arranged in one capsule. If the containers are mounted in several capsules, the capsules can be heated separately in this arrangement and the containers of this capsule can be emptied independently of the other containers.
  • the heating device can advantageously be an air heater arranged below the container in the capsule.
  • a heat exchanger with finned tubes through which hot water, hot water or steam flows and which heats air flowing around the tubes, can be used.
  • the air inside the capsule interior can be circulated.
  • the circulation can be forced by suitable devices.
  • the heat convection caused by temperature differences within a capsule is sufficient. This measure prevents heat build-up in the capsule area.
  • a wall is arranged in the interior of the capsule at a distance and essentially parallel to a vertical capsule wall, the space formed between the wall and the vertical capsule wall connecting the bottom region of the capsule to the ceiling region of the capsule.
  • FIG 1 In Figure 1, four bottles 1 to 4 are shown.
  • the containers stand on a perforated base plate 5, below which two radiators 6 are arranged.
  • the containers 1 to 4 are surrounded by a capsule consisting of five walls. In the figure, only the two side walls 7, 8 and the ceiling 9 are shown.
  • the containers are mounted in this capsule such that only the container housings are arranged inside the capsule, while the respective bottle valves 10 to 13, hoses 14 to 17 and the common extraction line 18 are accommodated outside the capsule. Together with the space in which the radiators 6 are arranged, the capsule forms a closed, essentially airtight space.
  • the material from which the capsule walls are made has good heat-insulating properties.
  • gas in the exemplary embodiment acetylene, which is stored together with a solvent distributed in a porous mass under pressure in the containers, can be removed from the containers.
  • the containers are heated in order to apply the heat of solution, absorption and / or evaporation required for the extraction.
  • the drawing does not show a control unit by means of which the temperature of the interior of the capsule can be regulated as a function of the container pressure. Such a regulation makes it possible to set a low temperature inside the capsule when the containers are full, but to set a higher temperature as the pressure in the containers decreases. In connection with the installation of the containers in a capsule, this measure leads to a surprisingly large saving in heating costs.
  • Air heated by the radiator 6 sweeps up through the perforated base plate 5 and between the containers 1 and 2 or 3 and 4. The air cools somewhat in thermal contact with the containers and flows back to the radiators 6 between the bottles 1 and 4 and the capsule walls 7 and 8 and between the containers 2 and 3.
  • This sketch can be seen; that the interior of the capsule should be kept as small as possible.
  • the containers assembled in the manner described are arranged within a space, the outer space of the capsule, in which the container valves 10 to 13, the hoses, is required 14 to 17 and the common sampling line 18 are housed to vent.
  • FIG. 2 shows a device according to the invention in which the containers 1, 2, 1 ', 2' are located within a mobile container 20.
  • the containers are combined into two groups 1 to 2 and 1 'to 2', each of which is enclosed in its own capsule.
  • the two groups are arranged to the right and left of an accessible central aisle 22.
  • An outer wall 8, 8 'of the capsules coincides with one of the container walls and is therefore, if possible, particularly well insulated against heat loss.
  • the entire container volume was heated and, in addition, the entire air content was changed several times per hour (approx. 3 times). According to the container interior is divided into two zones.
  • zone I internal of the capsule
  • zone 11 no heat is supplied to the outer area of the two capsules (zone 11), but this area is ventilated.
  • FIG. 1 A variant of a device according to the invention is shown in broken lines in FIG. Accordingly, an additional wall 19 or 19 'is mounted between the capsule walls 7 to 7' and the associated containers 1 and 2 'at a distance and parallel to the capsule walls 7 and 7'. A circulation of the air within the two capsules is promoted by the additional walls 19 and 19 '. The air heated by the radiator 6 sweeps up between the containers 1 and 2 or 1 'and 2', cools down and is removed from the area of the capsule ceiling via the space between the capsule wall 7 and the additional wall 19 (7 'and 19' directed into the bottom area of the capsule.
  • the device according to the invention can achieve a significant reduction in the heating energy requirement.
