Definitions
- the invention relates to a compressor device and a compression method having the features of independent claims 1 and 13.
- Such compressor devices are, for example, suitable for applications in the process industry, in mechanical engineering or in the hydrogen economy, in which it is necessary to compress a gas for transport, storage, processing or use.
- the gas to be compressed may be, for example, a non-corrosive, solids-free gas such as hydrogen, helium, carbon dioxide, argon, nitrogen or ethylene.
- a non-corrosive, solids-free gas such as hydrogen, helium, carbon dioxide, argon, nitrogen or ethylene.
- other gases or gas mixtures can be compressed.
- hydraulically driven piston compressors which are driven by means of a drive cylinder.
- the drive is effected by a movement of a drive piston, which is connected to a mechanical connecting means, such as a piston rod, with a compression piston, with the periodically a volume change of a compression space - and thus a gas compression - is effected.
- a hydraulically driven piston compressor can, for example, have a compression piston and a drive piston coupled to the compression piston (2-piston principle). Also a coupling of two compression pistons with a drive piston (3-piston principle) is possible.
- the use of a plurality of compression pistons may be used to compress a larger volume of the gas per unit time or to increase the compression of the gas.
- the gas can first be compressed in a first compression cylinder and then flow into a second and possibly a plurality of further compression cylinders and be further compressed.
- any number of such compression stages is conceivable.
- EP 0 064 177 describes a three-piston compressor device with up to four compression stages.
- a general problem in the operation of a hydraulically driven reciprocating compressor is a possible contamination of the gas, for example a sensitive gas such as hydrogen, by the hydraulic fluid, for example hydraulic oil, or contamination by unwanted particles.
- the contamination may e.g. by propagating into the compression space along the piston rod.
- the invention is based on the object to provide an improved compressor device, in particular, the risk of contamination of the gas is reduced.
- a compressor device for compressing a gas comprises at least one compression space in at least one compression cylinder.
- At least one drive piston is arranged in each case in at least two drive cylinders.
- the drive pistons separate the at least two drive cylinders each into two drive spaces.
- the at least one first or second drive space is periodically pressurized with a hydraulic fluid to move the respective drive piston.
- Such a compressor device may be formed, for example, by a hydraulic oil hydraulically driven piston compressor which is used for compression of gases such as hydrogen or helium in the at least one compression cylinder.
- the at least one compression space can be formed, for example, by a, in particular cylindrical, cavity in the at least one compression cylinder.
- the gas may flow into the at least one compression cylinder through a valve-controlled gas inlet and through a valve-controlled gas outlet.
- At least one drive piston is arranged in the at least two drive cylinders and separates the at least two drive cylinders into two drive spaces. If, for example, the hydraulic fluid flows into the at least one first drive space, the first drive piston is moved in the drive cylinder and the at least one first drive space increases. Since the first drive piston divides the first drive cylinder into two subspaces, the remaining drive space can be correspondingly reduced.
- the respective remaining drive spaces in the at least two drive cylinders are non-positively connected with each other by a fluid via a connecting piece.
- a frictional connection can also be understood as a fluidic coupling.
- the respective remaining drive spaces may be, for example, a third and a fourth drive space.
- the periodic loading of the drive chambers with hydraulic fluid can cause the drive pistons to move periodically coupled with each other due to the fluidic coupling.
- a drive space becomes larger as the other becomes smaller.
- the fluidic coupling can cause the respectively decreasing drive space to deliver the fluid to the other coupled drive space, which increases accordingly.
- the movement of the drive piston can thus be synchronized.
- the movement can take place in the sense of a differential cylinder, in which the at least one first drive piston performs an opposite movement to the at least one second drive piston.
- the at least one first drive piston can also perform a parallel movement to the at least one second drive piston in the sense of a synchronous hydraulic cylinder.
- the operation of a synchronous hydraulic cylinder is more expensive than the operation of a differential cylinder.
- a synchronization device may be provided. The synchronization device can cause a correction of the movement of the drive piston.
- the synchronization device can be formed for example by a pressure equalization line.
- the pressure compensation line may be arranged at one end of a drive space, at which a reversal of the movement of an associated drive piston takes place.
- the drive piston can be bridged by means of the pressure equalization line. This can be synchronized by means of the pressure equalization line, the fluid pressure between the two drive spaces of the respective drive cylinder.
- the pressure equalization line may further comprise a check valve. This principle can be understood as a healing or automatic stroke correction of the drive piston.
- the movement of the drive piston can be transmitted via at least one mechanical connection means to at least one compression piston movably arranged in the at least one compression cylinder.
- the at least one compression piston limits the at least one compression space in the at least one compression cylinder on one side, so that movements of the drive piston can be converted into a volume change of the at least one compression space.
- At least one drive piston can be driven via at least two drive pistons. In particular, two drive pistons each drive a compression piston.
- the at least one compression cylinder is spatially separated from the at least two drive cylinders by a distance.
- the distance may refer to a distance between the at least one compression cylinder and the at least two drive cylinders along a direction of movement of the at least one drive piston.
- the distance may be extended along the force of gravity.
- the at least one compression cylinder with the at least two drive cylinders has no common wall.
- a wall can be formed, for example, by a compression cylinder housing of the at least one compression cylinder or a drive cylinder housing of the at least two drive cylinders.
- a common wall may be present when the compression cylinder housing is adjacent to the drive cylinder housing.
- a common wall may mean that the compression cylinder is in contact with one of the at least two drive cylinders.
- the distance between the compression cylinders and the drive cylinder is at least as large as a maximum distance traveled by one of the respective at least one drive piston in the associated drive cylinder.
- the distance may in particular correspond to a stroke length of the at least one drive piston.
- the distance can therefore be understood as a distance between two positions of each of the at least one drive piston.
- the volume of an associated drive space may be minimal.
- the hydraulic fluid can change from outflows from the drive space to inflow into the drive space.
- the volume of the drive space can be maximum.
- the hydraulic fluid may change from inflow into the drive space to outflow from the drive space.
- the length can also be understood as the maximum stroke or as a maximum distance covered by the drive piston in the drive cylinder.
- At least one connecting space is arranged between the at least one compression cylinder and the at least two drive cylinders, which can be filled with a functional gas, in particular for flushing the at least one connecting space for detecting leaks in the at least one connecting space and / or blocking the at least one connecting space is.
- a first connection space may extend from the at least one first drive cylinder to the at least one compression cylinder.
- the second connection space may extend from the at least one second drive cylinder to the at least one compression cylinder.
- a common connection space may extend from the at least one first drive cylinder and the second drive cylinder to the at least one compression cylinder or a plurality of compression cylinders.
- the at least one mechanical connection means may extend from the at least one first drive cylinder and / or the at least one second drive cylinder to the at least one compression cylinder through the at least one connection space.
- the at least one connection space can be surrounded, for example, by a connection housing.
- the connecting housing can limit the at least one connecting space in a gastight manner. Therefore, the at least one mechanical connection means can be protected by the at least one connection space, for example against external contamination such as undesired gases and particles.
- the at least one connection space is filled with a functional gas.
- the at least one connection space can be filled with a purge gas.
- the purge gas can be removed by rinsing the connecting space unwanted gases and particles from the at least one connecting space.
- the at least one connection space is filled with a leak gas.
- a leak gas may be used to detect leaks in the at least one communication space.
- the at least one connection space can be filled with a sealing gas.
- the gas can serve to block the at least one connecting space for gaseous media.
- a barrier gas can prevent ingress of undesirable substances into the at least one communication space.
- the at least one compression cylinder and the at least two drive cylinders can be spaced from one another via the at least one connecting space.
- the at least one connection space at least as be long, such as a maximum distance covered by one of the at least one drive piston in the associated drive cylinder.
- the distance between the at least two drive cylinders and the at least one compression cylinder can thus be encompassed by the at least one connection space.
- the at least one connecting space can form a distance space, over which the at least two drive cylinders are spaced from the at least one compression cylinder.
- the at least one connecting space can in particular be designed as a lantern, so that an oil-free compression is made possible.
- At least one measuring device can be arranged in at least one of the two drive spaces, with which, for example, a position of the respective at least one drive piston in the associated drive cylinder can be determined.
- the particular position may serve to determine at which time the at least one first and second drive space is to be pressurized with fluid pressure.
- a reversal of motion of the respective at least one drive piston can be controlled.
- the at least one measuring device can be formed for example by a position sensor.
- the at least one measuring device can also be formed by a position measuring system, which can be arranged, for example, on the at least one drive cylinder.
- the at least one measuring device is arranged in the at least one connecting space in order to determine a position of the at least one mechanical connecting means.
- Another example of an arrangement of the at least one measuring device is on the at least one compression cylinder to determine a position of the at least one compression piston.
- the at least two drive cylinders are arranged below the at least one compression cylinder. Below this can be understood in terms of earth gravity.
- the at least two drive cylinders are thus arranged lower along the earth gravity than the at least one compression cylinder. As a result, for example, leaked from a drive chamber hydraulic fluid not due to the gravity of the at least two drive cylinders, spread in the direction of the at least one compression cylinder.
- a seal in particular a labyrinth seal, may be provided between the at least one compression cylinder and the at least one compression piston and / or the at least one mechanical connection means.
- a cooling device is arranged on the at least one compression cylinder, which dissipates waste heat arising during operation of the at least one compression cylinder.
- the cooling device may e.g. be designed as air or water cooling.
- the compressed gas it is also possible for the compressed gas to be able to be conveyed from a first compression space as a gas to be further compressed into a second, third or fourth compression space for compression in order to form a multi-stage compression.
- the gas to be further compressed can be conducted into any number of additional compression spaces for further compression.
- a valve device may be provided.
- a hydraulic actuation of the drive piston can be decoupled.
- the valve device can be controllable in dependence on data, information and / or process parameters which can be generated, for example, by means of the at least one measuring device.
- the valve device is controllable by a control system.
- the control system may control the admission of the at least one first and second drive space with the hydraulic fluid by means of the valve device.
- the control system can access data, in particular position data or movement data, from the at least one measuring device.
- the control system may access process parameters such as fluid pressure or amount of delivered hydraulic fluid (delivery) for control.
- the object is also achieved by a compression method having the features of claim 13.
