Definitions
- Pressure storage device for storing a medium and method for operating a pressure storage device
- the present invention relates to a pressure storage device for storing a medium and a method for operating a pressure storage device.
- Mobile compressed hydrogen storage systems can usually have several steel cylinders, similar to a cylinder bundle.
- the individual bottles can be filled in such a way that a central connection can be created during refueling up to a system pressure of around 700 bar.
- Another central line can empty the bundle of bottles to a fuel cell system and generate a system-related minimum pressure in the bottles.
- Each individual bottle can be provided with a controllable valve.
- the present invention provides an accumulator device for storing a medium according to claim 1 and a method of operating an accumulator device according to claim 7.
- the idea on which the present invention is based is to specify a pressure accumulator device for storing a medium under pressure and a method for operating a pressure accumulator device, which are characterized by an advantageous filling and emptying option, in which the stored medium penetrates into the material of the pressure vessel can be reduced or even avoided.
- an internal pressure of the pressure container can be kept at the lowest possible pressure level for as long as possible, even when the medium is being stored.
- the pressure accumulator device for storing a medium under pressure comprises at least a first pressure vessel with a first valve device and a second pressure vessel with a second valve device; at least one supply line and/or one discharge line, which is connected to the first valve device and to the second valve device and wherein the medium can be filled into the first pressure vessel and into the second pressure vessel via the supply line and/or the first pressure vessel and the second pressure vessel via the discharge line pressure vessel can be emptied; a control device which is connected to the first valve device and to the second valve device for opening and/or closing these and is set up to control filling and/or emptying of the first pressure vessel and the second pressure vessel with the medium, such that a predetermined pressure level in the first pressure vessel and in the second pressure vessel is assumed or fallen below.
- the type of emptying can reduce a risk of the mechanical properties of the pressure vessels being impaired, which can be shaped as steel cylinders, for example, by means of an intelligent filling and emptying strategy for the individual pressure vessels.
- the pressure accumulator device can itself comprise a pump for generating the necessary pressure, or it can be (externally) connected to such a pump.
- a filling tank itself can be under sufficient pressure and this pressure can then build up, at least partially, in the pressure vessels during filling.
- the predetermined pressure level can be a maximum filling pressure or a minimum residual pressure, which can serve as a reference for emptying, and up to which the internal pressure of the pressure vessel is at least lowered.
- the first pressure vessel and the second pressure vessel comprise a metal and in which hydrogen can be accommodated as a medium.
- the metal can be steel, for example.
- this is designed as a mobile system and set up to be installed in a vehicle or with a mobile structure.
- the first pressure vessel and the second pressure vessel each have a pressure sensor.
- the control device Via the pressure sensor, which can be connected to the control device and as a function of which the valve device can then be controlled, it is possible to determine whether the predetermined pressure level has been set in the pressure vessel(s) or how high the pressure is in the pressure vessel(s).
- the control device is set up to fill and/or empty the first pressure vessel and the second pressure vessel serially and in a predetermined sequence.
- Inflation can occur up to a predetermined inflation pressure and deflation can occur up to a predetermined deflation pressure specifying the respective predetermined pressure level.
- the first pressure vessel and the second pressure vessel are connected to one another in parallel via the supply line and/or the discharge line.
- the first pressure vessel and the second pressure vessel are filled with a medium through the supply line and the first valve device and the second valve device are activated and opened, the control device controlling the filling with the medium in such a way that that a predetermined pressure level in the first pressure vessel and in the second pressure vessel is assumed or fallen below; and/or emptying the first pressure vessel and the second pressure vessel through the discharge line and thereby activating and opening the first valve device and the second valve device, the control device controlling the emptying in such a way that a further predetermined pressure level in the first pressure vessel and in the second pressure vessel is undercut.
- the first pressure vessel and the second pressure vessel are filled in such a way that a pressure of the medium in the first pressure vessel and in the second pressure vessel is raised successively or simultaneously to or above a predetermined filling pressure, or the first pressure vessel is emptied and of the second pressure vessel takes place in such a way that a pressure in the first pressure vessel and in the second pressure vessel is lowered sequentially or simultaneously to or below a predetermined evacuation pressure.
- an emptying and filling cycle takes place, the first pressure vessel being emptied and a pressure of the medium in the first pressure vessel being lowered to or below a predetermined emptying pressure and a pressure of the medium in the second pressure vessel being only partially lowered thereafter at least the first pressure vessel is refilled, and when it is emptied again, first a pressure of the medium in the second pressure vessel is lowered to or below the predetermined emptying pressure.
- first pressure vessel instead of the first pressure vessel, several pressure vessels can also be emptied and filled in the same way as the first pressure vessel and then, starting from a specific pressure vessel, filling and emptying can take place as described for the second pressure vessel.
- the first pressure vessel and the second pressure vessel are emptied sequentially or simultaneously to a predetermined emptying pressure and only then are the first pressure vessel and the second pressure vessel emptied sequentially or simultaneously below the predetermined emptying pressure.
- first pressure vessel instead of the first pressure vessel, several pressure vessels can also be emptied and filled in the same way as the first pressure vessel and then, starting from a specific pressure vessel, filling and emptying can take place as described for the second pressure vessel.
- the method can advantageously also be distinguished by the already mentioned features of the pressure accumulator device and vice versa.
- FIG. 1 shows a schematic representation of a pressure accumulator device for storing a medium under pressure according to an embodiment of the present invention
- FIG. 2 shows a block diagram of method steps of a method for operating a pressure accumulator device according to an exemplary embodiment of the present invention.
- FIG. 1 shows a schematic representation of a pressure accumulator device for storing a medium under pressure according to an exemplary embodiment of the present invention.
- the pressure storage device 10 for storing a medium M under pressure comprises; at least one first pressure vessel B1 with a first valve device VI and a second pressure vessel B2 with a second valve device V2, FIG. 1 showing further pressure vessels B3 to Bn with corresponding valve devices V3 to Vn.
- Pressure accumulator device 10 can comprise at least one supply line Z and/or one discharge line A, for example as a pipe, which is connected to the first valve device VI and to the second valve device V2 and also to the other valve devices V3 to Vn, and via the supply line Z the medium can be filled in the pressure vessels Bl to Bn and/or the pressure vessels Bl to Bn can be emptied via the discharge line A.
- the supply line Z and the discharge line A are shown in FIG.
- the pressure accumulator device 10 further comprises a control device SE, which is connected to the first valve device VI and to the second valve device V2 and the other valve devices for opening and/or closing them and is set up to fill and/or empty the first pressure vessel Bl and the second pressure vessel B2, and also the other pressure vessels B3 to Bn, to be controlled with the medium in such a way that a predetermined pressure level in the first pressure vessel B1 and in the second pressure vessel B2, and in the further pressure vessels B3 to Bn, is assumed or fallen below.
- the predetermined pressure level can include a minimum pressure for storing the medium, which is reached during emptying and can be maintained over as long a time as possible in order to reduce the penetration of the medium into the material of the respective pressure vessel.
- the pressure vessels B1 to Bn can include a metal and the medium can include hydrogen. At low pressure, the introduction of hydrogen into the metal can then be reduced.
- a specific operating strategy can advantageously be carried out by means of the control device and the supply line and/or discharge line, in which case a filling and/or emptying cycle can take place in which each or as many pressure vessels as possible is only filled with the minimum pressure over a maximum period of time, so that the Hydrogen entry (entry of the medium into the wall material of the pressure vessel) can be minimized.
- This can be done, for example, by serial and not simultaneous filling or emptying of the individual pressure vessels one after the other, with the first pressure vessel B1 being able to be emptied down to a predetermined minimum pressure (predetermined emptying pressure) before the second pressure vessel B2 is emptied, as can the other pressure vessels B3 to Bn. If a pressure vessel is then not completely emptied during an emptying cycle, it can then be emptied with priority in the next emptying cycle.
- an impairment of the mechanical properties of the pressure vessel can be reduced by each pressure vessel at least temporarily with the at least within two emptying cycles over a certain period of time Minimum pressure is applied.
- Minimum pressure is applied.
- the pressure vessels can be emptied, in particular in a manner already mentioned.
- the at least one of the pressure vessels can be emptied down to the predetermined emptying pressure, which can represent a minimum residual pressure.
- the pressure tanks can be emptied one after the other in this way. It can then be refilled.
- that pressure container can then be emptied first which was not emptied down to the predetermined emptying pressure in the previous emptying cycle, as well as all others which were not previously emptied, advantageously in series relative to one another.
- the entire system ie all pressure vessels, can first be emptied down to a certain pressure (transitional pressure) before the serial emptying of all or some pressure vessels is carried out.
- the pressure vessels can be filled during filling, for example (predetermined filling pressure) of about 700 bar.
- the drain line A can evacuate the pressure vessels to a fuel cell system, and create a system-inherent minimum pressure (predetermined evacuation pressure) in the pressure vessels.
- FIG. 2 shows a block diagram of method steps of a method for operating a pressure accumulator device according to an exemplary embodiment of the present invention.
- the first pressure vessel and the second pressure vessel are filled S1 with a medium through the supply line and the first valve device and the second valve device are actuated S2 and opened, with the control device controlling the filling with the medium in such a way controls that a predetermined pressure level in the first pressure vessel and in the second pressure vessel is assumed or fallen below; and/or emptying S3 of the first pressure vessel and of second pressure vessel through the derivation line and thereby activating S4 and opening the first valve device and the second valve device, wherein the control device controls the emptying in such a way that a predetermined pressure level in the first pressure vessel and in the second pressure vessel is undershot.
