Definitions

  • the invention relates to a submarine with the features specified in the preamble of claim 1.
  • the invention has the object to provide a submarine, which ensures that harmful gas, which is used by a arranged in the pressure hull of the submarine device or generated, can not get into the outside environment of these devices in an inadmissible amount.
  • the submarine according to the invention has a pressure body in the usual way. At least one device which uses and / or generates a noxious gas is arranged in the pressure body. Under a noxious gas is to be understood as such a gas, which leads to a danger to the crew of the submarine from a certain concentration in the atmosphere of the pressure hull.
  • the devices which use and / or generate noxious gas are arranged in a closed space within the submarine, wherein means for noxious gas conversion and / or Schadgasadsorption are arranged in this closed space.
  • the aim of this measure is technologically simple and therefore cost-effective escape from these devices harmful gas in the closed space and within this space, in which it may be a device completely surrounding the housing or a closed department of the pressure hull, with the means for To convert harmful gas conversion into a harmless substance or with the means for To bind Schadgasadsorption in the closed space.
  • a means of harmful gas conversion here are conveniently used chemical reactors in which, for example, takes place by oxidation, the harmful gas conversion.
  • Means for Schadgasadsorption are such facilities in which the noxious gas is preferably bound to solids.
  • a device of the submarine using and generating noxious gas may be a methanol reformer.
  • D. h. It is advantageously provided to arrange the methanol reformer of a submarine in a closed space in which at least one oxidation reactor is arranged, in which the possibly exiting at the methanol reformer due to leaking harmful gases methanol, hydrogen and carbon monoxide in harmless carbon dioxide and water are converted.
  • a device using noxious gas in the sense of the invention may be a fuel cell system of a submarine.
  • the advantageous arrangement of the fuel cell system in a closed space with an oxidation reactor therein for converting hydrogen into harmless water prevents hydrogen from getting into the pressure vessel atmosphere of the submarine.
  • the means for Schadgasumwandlung and / or Schadgasadsorption preferably part of a arranged in the closed space air circulation device.
  • the air circulation device With the air circulation device, the air in the closed space is circulated within the room. This measure will First, it prevents harmful gas from accumulating within the confined space in certain places, such as low-lying areas of the room in larger quantities.
  • the particular advantage of using an air circulation device in the closed space lies in the fact that the air sucked in by it in the closed space can be fed directly to the means for harmful gas conversion and / or Schadgasadsorption via a supply line, wherein any harmful gas contained in the air in the Means for harmful gas conversion and / or Schadgasadsorption is converted or bound before the air is returned to the closed space.
  • any harmful gas contained in the air in the Means for harmful gas conversion and / or Schadgasadsorption is converted or bound before the air is returned to the closed space.
  • means for gas analysis are arranged in the closed space. These means for gas analysis serve to detect the presence of noxious gases outside of a noxious gas using and / or generating device in the closed space and preferably also to determine the concentration of the noxious gas in the closed space.
  • the means for gas analysis are connected to a control device which can cause an alarm when detected harmful gas and can adjust the air flow through the air circulation device by appropriate control of a gas conveyor of the air circulation device to the ruling in the closed space noxious gas concentration.
  • the air circulation device may also have at least one air cooler.
  • This embodiment is typically of particular advantage when the device using and / or generating the noxious gas is a heat-generating device Device, such as a fuel cell system or a methanol reformer is.
  • the air warmed by these devices in the closed space is permanently cooled down by the air cooler. In this respect, it is not necessary to use in the enclosed space such system components, which are designed especially for the otherwise, ie without cooling the air prevailing temperatures there.
  • the walls surrounding the closed space are intended to prevent a noxious gas in the space from entering the outside environment of that space. Due to the conversion and / or binding of noxious gas within the closed space, in particular in connection with the use of an air circulation device, it is not necessary to form the closed space in which the noxious gas using and / or generating device is completely closed in a gastight manner the air in the closed space already before it can escape from the room in the pressure vessel atmosphere, in the room is freed from the harmful gas so that at most uncritical amounts of harmful gas can escape from the closed space.
  • the use of pressure equalization openings in the closed space is advantageously possible, which is provided according to a further preferred embodiment of the invention. With these pressure equalization openings, pressure compensation may take place in the closed space if pressure differences between the pressure-body atmosphere and the atmosphere occur.
  • a plurality of noxious gas using and / or generating devices are arranged in a submarine, they can be accommodated separately from each other in each case in a separate closed space with the features described above.
  • a submarine having a fuel cell plant and a methanol reformer it is possible to arrange the fuel cell plant and the methanol reformer together in a closed space as described above.
  • Submarine 2 shown schematically has a pressure body 4.
  • a pressure body 4 In the pressure body 4 is a noxious gas using and / or generating device 6 z.
  • an air circulation device 10 is also arranged in the space 8.
  • the air circulation device 10 has a line 12, on which a plurality of air intake 14 are formed. At one end of the line 12 goes into a wiring harness 16 and at the other end in a wiring harness 18 via. The strands 16 and 18 open in the interior of the space eighth
  • a gas pump 20 is arranged in each case.
  • an air cooler 22 is arranged in the two line strands 16 and 18, respectively. Downstream of the air cooler 22 follows in each of the line strands 16 and 18, an oxidation reactor 24 as a means for harmful gas conversion.
  • adsorption devices could also be arranged here as agents for the adsorption of harmful gases.
  • two gas sensors 30 and 32 are arranged in the interior of the space 8 as means for gas analysis.
  • the gas sensors 30 and 32 are used to detect a pollutant gas used or generated by the device 6 in the interior of the space 8 and to determine the harmful gas concentration there.
  • the gas sensors 30 and 32 are signal-connected to a control device 34, which causes an alarm in the detection of noxious gas.
  • the control device 34 also serves to control the two gas delivery pumps 20. Therefore, the control device 34 is signal-connected with the two gas delivery pumps 20 via corresponding line connections.
  • pressure outlet openings 36 and 38 are formed on the outer wall bounding the space 8.
  • the operation of the embodiment according to Fig. 2 is as follows: In the closed space 8, the air therein is continuously circulated by means of the air circulation device 10, wherein the air sucked by the two gas pump 20 via the air intake 14 and conveyed to the air outlets 26. In this case, the air flowing through the line strands 16 and 18 in the two air coolers 22 is cooled.
  • the delivery rate of the air circulation device 10 can be increased by appropriate control of the gas delivery pumps 20 by the control device 34.
  • the gas delivery pumps 20 suck the charged with the noxious gas air in the air circulation device 10 before it can escape from the room 8.
  • the gas feed pumps 20 convey the noxious gas to the oxidation reactors 24 located in the line strands 16 and 18.
  • the noxious gas contained in the supplied air stream is converted by appropriate oxidation processes into harmless substances. These substances, together with the purified air, are introduced again via the air outlets 26 and 28 into the interior of the space 8.
  • the exemplary embodiment described above is only to be understood as a matter of principle, ie it is also possible for a plurality of pollutant-using and / or generating devices to be arranged in the space 8 at the same time.
  • the gas sensors and the number of oxidation reactors or adsorption devices is not generally set to two but can be adapted to the specific situation.
  • a plurality of closed spaces 8 may be provided, each with arranged therein noxious gas generating and / or using devices.
