  • the submarine has a hot fluid supply and a cold fluid supply.
  • the temperature of the heat exchange fluid in the hot fluid supply is 120° C. to 220° C., preferably 130° C. to 160° C.

  • each CO 2 absorption device has a gas outlet, the gas outlet being arranged on the other side of the solid and the heat exchange device.
  • the arrangement of the gas inlet and the gas outlet is such that the flowing gas flows around or through the solid.
  • the gas inlet can, for example and particularly preferably, be arranged above and the gas outlet, for example, below the solid of the heat exchange device. This has the advantage that the solid is flown from above, which minimizes turbulence in the solid.
  • Ambient air can be supplied through the gas inlet and CO 2 -depleted gas can be supplied to the ambient air through the gas outlet. In this way, the breathing air can be freed from CO 2 .
  • ambient air means the air that is inside the submarine, in particular the air in the area in which people are or can usually be found.
  • the ambient air can be used by suitable circulation pumps, fans or pumps and Suction devices and by means of pipes, shafts or guiding devices from the submarine are fed to the gas inlet and are transported back from the gas outlet in a corresponding manner.
  • the gas outlet can be connected to a pump for evacuation.

  • the pump can be permanently connected.
  • the pump can also be connected to more than one CO 2 absorption device in a switchable manner, for example by switchable valves and corresponding pipes, so that the connection can be separated so that evacuation is only carried out in a targeted manner when this is desired. This separability can already be achieved with a simple valve.
  • the first CO 2 absorption device, the second CO 2 absorption device and the third CO 2 absorption device can be independently operated in at least an absorption mode and a desorption mode. Additional operating modes are also possible, for example a standby mode, heating mode or cooling mode or maintenance mode.

  • Switching between absorption mode and desorption mode can be load-dependent, mission-dependent, time-dependent or load-dependent.
  • the CO2 The absorption device would then be provided with appropriate sensors in order to be able to detect a load-dependent, time-dependent or also load-dependent switching point and to be able to change the operating mode via an appropriate controller.
  • the switching points can also be variable, in particular they can also be set as a function of the mission-dependent mode of operation of the submarine.
  • the loading can also be estimated, for example, over time and the volume of air conveyed.
  • the invention is not limited to just three CO 2 absorption devices, but there are preferably more, for example four to six, but there can also be significantly more. This has the advantage that, on the one hand, greater reliability is guaranteed. On the other hand, an easier adaptation to the needs, for example with different manning levels, can also take place.
  • a CO 2 absorption device is preferably designed as follows:
  • the CO 2 absorption device is used to separate carbon dioxide from a gas mixture, in particular to separate carbon dioxide from the breathing air on board a submarine.
  • the CO 2 absorption device has a solid for absorbing carbon dioxide.
  • the solid is preferably a polymer with functional amine groups.
  • the CO 2 absorption device has a heat exchange device in the solid.
  • the heat exchange device serves to heat the solid for desorption of the carbon dioxide and to cool it down again after the desorption.
  • the solid can also be cooled during the absorption of the carbon dioxide in order to prevent unwanted warming up due to the exothermic reaction and thus to optimize the absorption.
  • the CO 2 - absorption device has a shell, wherein the shell can be evacuated.
  • a pressure of 10 kPa is also regarded as a vacuum for the purposes of the invention, since this allows oxygen to be sufficiently removed from the solid prior to heating and the desorption of carbon dioxide is sufficiently supported.
  • the shell must be designed to be sufficiently stable in order to be able to withstand such a pressure, it also having to be taken into account that the pressure in the can vary greatly inside a submarine and can also reach values of up to 160 kPa.
  • the CO 2 absorption device has an inlet in the shell for the gas mixture, the inlet being arranged above the solid. As a result, the solid is flown through from top to bottom.
  • the solid is in particulate form for absorbing carbon dioxide.
  • particulate is, for example, spherical.
  • the size of the particles of the solids is preferably in the range from 0.1 mm to 50 mm, preferably from 1 mm to 10 mm.
  • the use of a particulate solid also makes it much easier to replace it in a spatially cramped submarine, and the storage of the solid is also simpler compared to disc-shaped solids, for example.
  • the casing particularly preferably has a round cross section.
  • the inlet is designed to generate a radial flow of the gas mixture above the solid. For example and preferably, this is not arranged centrally, but laterally offset, with the central axis of the inlet pipe not pointing towards the center of the device and preferably running horizontally or parallel to the inlet-side surface, i.e. upper plane, of the particulate solid. As a result, the flow direction of the inlet is not directed towards the center of the device.
  • the flow direction of the inlet preferably runs horizontally and therefore has no vertical component which is directed towards the particulate solid. As a result, the kinetic energy is used to generate a radial flow.
  • the inlet has a significantly smaller cross section than the shell in the horizontal (preferably round) cross section.
  • This causes the gas mixture to flow in at a higher velocity, thereby creating a radial flow in the shell, which is preferably largely parallel to the surface of the solid.
  • the subsequent flow of the gas mixture through the solid from top to bottom then takes place with a correspondingly lower vertical flow velocity component (due to the significantly larger cross section with the same volume flow).
  • This has two positive effects. On the one hand, this produces a uniform flow that does not or only slightly whirl up the particulate solid. On the other hand increases the lower vertical Flow velocity component the contact time with the solid and thus the absorption of carbon dioxide from the gas mixture.
  • guide elements for generating or intensifying a radial flow are arranged in the shell and at the level of the inlet.
  • the radial flow can be further optimized and the most uniform possible flow onto the solid can be achieved.
  • the guide elements are designed in the form of vertically arranged guide plates, which are arranged inside at the upper end of the casing.
  • the guiding elements particularly preferably have a curved shape in order to promote the radial flow. More preferably, the position and orientation of the inlet and the position and shape of the guide elements are coordinated with one another for an optimal radial flow.
  • the baffles are shaped coaxially to an imaginary axis in the shape of a segment of a circle, which can form a segment of a circle of 45° to 180°, and can have a height that corresponds at least to the diameter of the inlet pipe. They can be arranged directly behind the inlet pipe, so that the inflowing gas is guided directly through the guide elements.
  • the radial flow of the gas mixture is preferably a laminar flow and not a turbulent flow. In addition to the size of the inlet pipe and thus the flow rate of the gas, this can also be supported, for example, by the guide elements. The lower the turbulent part of the flow, the lower the risk of turbulence in the solid.
  • the device has a cooler, the cooler being arranged in front of the inlet. This cools the incoming gas, allowing more CO 2 to be absorbed.
  • the cooler is particularly preferably designed in the form of a heat exchanger, the heat exchanger being connected to the device in such a way that the gas first flows through the heat exchanger, from there into the device and is then fed back into the heat exchanger in such a way that the heat exchanger the gas entering the inlet cools and, in turn, heats the gas exiting the outlet. This minimizes the energy requirement and does not affect the ambient temperature.
  • the solid is arranged in a horizontally arranged absorption layer, the absorption layer having an upper delimiting element on the upper side and a lower delimiting element on the underside.
  • the upper delimiting element and the lower delimiting element are each formed by a grid or perforated plate, i.e. by something through which the gas mixture can flow easily, but which securely holds back the solids. Therefore, the openings of the grid or the perforated plate are smaller than the particle size of the solid.
  • the absorption layer is particularly preferably disc-shaped, so the thickness is less than the diameter.
  • the solid is present in the absorption layer as a bed, which suggests a degree of filling in the order of 2 A. The flow resistance of the solid is correspondingly high.
  • the absorption layer extends over the entire flow cross section, so that the flow has to flow through the solid.
  • the thickness of the absorption layer to be flowed through is essentially constant over the entire flow cross section.
  • the delimiting elements can also be multi-layered, for example from a first coarse grid with very large openings (larger than the solid), but with very stable support elements. A fine-meshed fine grid, for example, is then arranged on this first coarse grid, which holds back the solid and is itself carried and supported by the first coarse grid. This combines the optimum load-bearing capacity of the first coarse grid with the optimum retention properties of the second fine grid.
  • the upper delimiting element has vertical structures, the vertical structures extending into the solid. These vertical structures serve to prevent the solid from slipping, for example when surfacing, descending or heeling, in particular if there is a compensation volume at the top to accommodate changes in volume.
  • the vertical structures can be arranged vertically downwards, for example Elements are formed which, for example, can have the same structure as the delimiting element itself, for example also consist of a grid.
  • the upper delimiting element itself is corrugated and thus has elevations and depressions itself. Since the solid is flown from above, it is not fluidized, as could be the case with a flow from below. Therefore, these vertical structures are sufficient for stabilization.
  • the CO 2 absorption device has a pump for evacuating the envelope, the pump preferably being a water ring pump.
  • the water ring pump has two main advantages. On the one hand, direct contact is avoided by the liquid gap in the pump, so that this pump is comparatively quiet, which reduces the acoustic signature of the submarine.
  • the CO 2 absorption device has a pneumatic conveying device for the solid.
  • the pneumatic conveying device has a connecting pipe.
  • the connecting tube can be evacuated to remove the solid from the shell.
  • the solid can be introduced into the shell with a gas flow through the connection pipe.
  • the solid In order to promote the discharge of the solid, it can be supported, for example, by supplying gas through the inlet gas while evacuation is taking place through the connecting pipe. This achieves a promotional gas flow.
  • pumping evacuating
  • pumping can take place at the shell at the same time as conveying with a gas stream, for example during desorption. Also this allows a continuous gas flow for the entry of the solid to be achieved.
  • the heat exchange device has a fluid as the heat carrier.
  • the heat exchange device has a lamellar design.
  • the fins of the heat exchange device are particularly preferably arranged parallel to the direction of flow.
  • the submarine has a heat recovery device for recovering the heat of the heat exchange fluid.
  • the heat recovery device includes a storage device having connections to the heat exchange fluid outlets for storing high temperature heat exchange fluid discharged from a heat exchange fluid outlet and connections to the heat exchange fluid inlets. Desorption takes place at temperatures of, for example, 120°C to 150°C. After the desorption has been completed, the correspondingly warm heat exchange fluid is pumped into the storage device and from there later into another CO 2 absorption device if this is to be heated up for desorption after evacuation.
  • the heat recovery device comprises a connection between the heat exchange fluid outlet of a first CO 2 absorption device and the heat exchange fluid inlet of a second CO 2 absorption device.
  • the warm heat exchange fluid can preferably be conveyed via the heat recovery device from any heat exchange fluid outlet of any desired CO 2 absorption device to any heat exchange fluid inlet of any other desired CO 2 absorption device.
  • the gas outlets of the CO 2 absorption devices can be connected to a water ring pump. Since, in addition to CO 2 from the breath, water is also bound by the solid and released again in the desorption mode, a large amount of gaseous water is also released in this phase. In a water ring pump, this is condensed and removed from the gas stream easily removed. In addition, a water ring pump is comparatively quiet, which has a positive effect on the acoustic signature of the submarine.
  • the gas outlets of the CO 2 absorption devices can be connected to the water ring pump via a condenser. This increases the condensing capacity in addition to the water ring pump, which reduces the vapor pressure. As a result, more CO 2 can be extracted by the water ring pump. This lengthens the cycles.

  • a suction device can first be connected to the corresponding flange in order to remove the particulate solid.
  • a filling can then be connected to the flange in order to introduce the particulate solid into the CO 2 absorption device with the aid of a gas stream.
  • the submarine has a further medium-temperature fluid supply in addition to the hot fluid supply and the cold fluid supply, the temperature of the heat exchange fluid in the cold fluid supply being lower than the temperature of the heat exchange fluid in the medium-temperature fluid supply and the temperature of the heat exchange fluid in the medium-temperature fluid supply being lower than that Temperature of the heat exchange fluid in the hot fluid supply.
  • a cooler is arranged between the air inlet and the inlets of the heat exchange devices. This cools the incoming gas, allowing more CO 2 to be absorbed.
  • the cooler is particularly preferably designed in the form of a heat exchanger, with the heat exchanger cooling the gas flowing into the inlet and, in return, the out gas exiting the outlet is heated. This minimizes the energy requirement and does not affect the ambient temperature.
  • the cooler has a water drain.
  • water condensed in the cooler can be removed, which leads to a lower water absorption of the solid for absorbing carbon dioxide.
