Definitions
- Tank device for temperature pressure relief of a hydrogen tank
- the invention relates to a tank device for relieving the temperature pressure of a hydrogen tank, for example for use in vehicles with a fuel cell drive or in vehicles with a hydrogen drive.
- DE 10 2017 212 485 A1 describes a device for storing compressed fluids that serve as fuel for a vehicle, the device comprising at least two tubular tank modules and at least one high-pressure fuel rail with at least one integrated control and safety system.
- the at least two tubular tank modules are made of metal and are modularly connected to the at least one high-pressure fuel rail with the at least one integrated control and safety technology to form a module with flexible geometry.
- the overflow valve can close in the event of an accident with the device for storing compressed fluids or if a line within the device breaks, so that no gas can escape from the storage unit.
- the safety valve should ensure, for example in the event of a fire or a temperature increase above a predetermined threshold value, that the hydrogen can be routed out of the tank module, for example, in order to prevent the tank module or even the entire device for storing compressed fluids from exploding.
- the tank device according to the invention with the characterizing features of claim 1 has the advantage, in a structurally simple manner, that when the tank device is exposed to heat, the tank device is emptied easily and quickly, with targeted venting of the gaseous medium, for example hydrogen, preventing the tank device from bursting Tank device is prevented.
- the gaseous medium for example hydrogen
- the tank device for relieving the temperature pressure of a hydrogen tank has at least two tank containers and a supply line that can be connected to the tank containers.
- Each of the at least two tank containers has at least one shut-off valve at one end, which shut-off valve is arranged between the respective tank container and the supply line.
- the tank containers are completely enclosed by a housing element and/or encapsulated from the environment, in particular in a pressure-tight manner, with at least one sacrificial container being arranged in the tank device.
- the sacrificial container is fluidly connected to the tank containers by means of a pressure relief valve.
- the pressure building up in the tank containers can be reduced via the sacrificial container. Because if the pressure in the tank containers increases due to the heat input, the overpressure valve on the sacrificial container is triggered, so that hydrogen can be drained from the tank containers into the sacrificial tank container. In this way, the pressure building up in the tank containers is reduced by means of one or more sacrificial containers. In this way, the tank device can be prevented from bursting.
- the sacrificial container is filled exclusively with 1 bar of nitrogen. In this way, the pressure in the tank containers can be reduced in a simple manner.
- the sacrificial container is filled exclusively with 1 bar of hydrogen. In this way, the pressure in the tank containers can be reduced in a simple manner.
- At least one safety valve is arranged at another end of the tank container.
- the tank device can be prevented from bursting or, depending on the heat input and pressure build-up, it may no longer be necessary to open the safety valves.
- the safety valve has a fluid-filled glass ampoule, so that the glass ampoule is caused to burst when the temperature in the environment increases, and the safety valve can thus be unlocked.
- the safety valve comprises a fusible medium, for example wax, with the fusible medium melting when the temperature of the environment increases and the safety valve can thus be unlocked.
- a fusible medium for example wax
- the tank containers can be connected to a discharge line by means of the safety valve.
- the gaseous medium for example hydrogen
- the tank containers can be connected to a discharge line by means of the safety valve.
- the at least two tank containers are made of steel. The choice of material results in cost savings.
- the at least two tank containers can be connected to an inlet area of a consumer system, preferably an anode area of a fuel cell system, via the shut-off valve.
- the tank device described is preferably suitable in a fuel cell system for storing hydrogen for the operation of a fuel cell.
- the tank device can be used in vehicles with a fuel cell drive.
- the tank device can be used in vehicles with hydrogen as the drive.
- the drawing shows exemplary embodiments of a tank device according to the invention for relieving the temperature pressure of a hydrogen tank. It shows in
- FIG. 1 first exemplary embodiment of a tank device according to the invention in a schematic view
- FIG. 2 shows a second exemplary embodiment of a tank device according to the invention in a schematic view.
- Fig.l shows a first embodiment of a tank device 1 according to the invention in a schematic view.
- the tank device 1 has a plurality of tank containers 10 which are of essentially cylindrical design and are made of steel.
- the respective ends 26, 27 of the respective tank container 10 have a conical taper and thus a typical bottleneck structure.
- a sacrificial container 14 is arranged in the tank device 1 next to the tank containers, which is fluidically connected to the tank containers 10 by means of a pressure relief valve 13 .
- the sacrificial container 14 is filled exclusively with 1 bar of nitrogen.
- due to the oxyhydrogen reaction when hydrogen and oxygen are combined it should be ensured that the victim container does not contain oxygen.
- the sacrificial container 14 is therefore at atmospheric pressure.
- the sacrificial container 14 can also be filled exclusively with 1 bar of hydrogen.
- any number of sacrificial containers 14 can be arranged in the tank device 1 .
- tank container 10 and the sacrificial container 14 are completely enclosed by a housing element 12 and encapsulated in a pressure-tight manner in relation to an environment 120 .
- One end 26 of the respective tank container 10 is connected to a supply line 4 by means of a shut-off valve 8 .
- This feed line 4 is connected by means of a further valve 2, for example to an inflow area of a consumer system, for example an anode area of a fuel cell system.
- the tank device 1 can provide hydrogen for a fuel cell arranged in a fuel cell system.
- FIG. 2 shows a second exemplary embodiment of a tank device 1 according to the invention in a schematic view.
- the second exemplary embodiment largely corresponds to the first exemplary embodiment in terms of function and structure.
- the respective tank container 10 is connected here at the other end 27 to a discharge line 70 via a tank discharge line 71 .
- a safety valve 7 is arranged for each tank container 10 in the tank discharge line 71 .
- the safety valves 7 have a fluid-filled glass ampoule, so that if the temperature of the environment 120 increases, the glass ampoule will burst and the safety valve 7 will be unlocked and opened.
- the safety valve 7 has a fusible medium, for example wax, so that this melts when the temperature of the environment 120 increases and the safety valve 7 can thus be unlocked.
- the sacrificial container 14 it is also possible for the sacrificial container 14 to be fluidically connected to the individual tank containers 10 via a pressure relief valve 13 in each case.
- the functioning of the tank device 1 is as follows: When the fuel cell system is functioning properly, the fuel cell is supplied with hydrogen from the tank containers 10 .
- the shut-off valves 8 are designed in such a way that a reliable supply to the fuel cell is ensured.
- the pressure building up in the tank container 10 should be reduced as quickly as possible in the first exemplary embodiment, for example to prevent the tank container 10 from exploding.
- the power supply to the shut-off valves 8 is also interrupted, so that no more hydrogen can escape from the tank containers 10 .
- the sacrificial container 14 is here by means of the pressure relief valve
- the sacrificial container 14 is at atmospheric pressure and contains only nitrogen or hydrogen, so that the excess pressure in the tank containers 10 caused by the heat input can be discharged into the sacrificial container 14 .
- the safety valves 7 should be closed as quickly as possible after the heat input occurs trigger, so that the hydrogen can be routed from the tank containers 10 via the tank discharge line 71 into the discharge line 70 in order, for example, to prevent the tank container 10 from exploding.
- the power supply to the shut-off valves 8 is also interrupted, so that no more hydrogen can escape from the tank containers 10 .
- the sacrificial container 14 is fluidly connected to the tank containers 10 by means of the pressure relief valve 13 or by means of a respective pressure relief valve 13 for each tank container 10 .
- the sacrificial container 14 is in a vacuum state, so that the excess pressure in the tank containers 10 caused by the heat input can be discharged into the sacrificial container 14 .
- the resulting pressure on the tank containers 10 can be released at least partially via the sacrificial container 14 and the pressure in the tank containers 10 can be reduced.
- the pressure for opening the pressure relief valve 13 is slightly higher than the maximum permissible pressure in the tank containers 10, but lower than the bursting pressure of the tank containers 10, i.e. the tank containers 10 are not caused to burst due to the heat input. This is therefore within the safety range of the tank container 10. In this way, just enough pressure is reduced so that the respective tank container 10 is not damaged.
- the safety valves 7 trigger and gaseous medium, hydrogen, flows out of the tank containers 10 in the direction of the discharge line 12 and is safely emptied into the environment 120 .
- the opening of the safety valve 7 is irreversible, since in the event of a fire the tank containers 10 are emptied quickly and efficiently and the safety valve 7 should remain in the open state to ensure complete emptying.
- the tank device 1 for storing a gaseous medium can also be used, for example, for storing hydrogen in vehicles with a hydrogen combustion engine as the drive, in addition to vehicles powered by fuel cells.
