Definitions
- Liquid separation device for a compressor system
- the present invention relates to a liquid separation device for a compressor system and a compressor system with such a liquid separation device.
- oil used for lubrication and cooling is separated after the compression process via suitable oil separation devices so as not to be introduced into downstream compressed air systems.
- the separated oil is then fed back into the compressor, for example the screw block in oil-lubricated screw compressors.
- a check valve is arranged in the return line.
- an additional nozzle must be installed in the return line in order to limit air losses from the compressor, since there is predominantly air on the clean side of the coalescence filter and only small amounts of oil in relation to it. Due to the arrangement of the check valve and the nozzle in the external return line the check valve and the nozzle are exposed to corresponding ambient temperatures, so that, for example, at low temperatures there is a risk of the check valve and / or the nozzle freezing.
- the oil must be extracted from the clean air side of the coalescence filter via an additional riser pipe.
- the arrangement creates the risk of a permanent air leakage flow.
- residual oil quantities can remain below the dip tube and can be introduced into the compressed air system.
- a liquid separation device for a compressor system has at least one coarse separation unit, which has at least one coarse separator and a liquid removal device, at least one fine separation unit, which has at least one fine separator and a liquid removal device, and at least one liquid removal channel, which drains a liquid from the respective liquid removal devices.
- the at least one liquid removal channel is formed in the liquid separation device.
- the liquid separation device is used to separate a liquid from a liquid-gas volume flow of the compressor system.
- the liquid separation device downstream of an oil-lubricated compressor, such as an oil-lubricated screw compressor, in the volume flow direction can separate an oil from an oil-air volume flow.
- the liquid separator device is an oil separator device that separates the oil from the compressed compressed air.
- other liquids that serve, for example, to cool and/or lubricate the compressor can also be separated.
- a gas other than air can also be compressed by the compressor.
- the liquid separation device is designed as a multi-stage liquid separation device, which comprises at least one coarse separation unit and one fine separation unit, i.e. at least two stages.
- the multi-stage design of the liquid separation device can, for example, increase the degree of separation.
- the multi-stage design can also have a positive effect on the service life of the individual separators used, especially fine separators.
- a baffle plate for example, can be used as a coarse separator in the coarse separation unit, onto which the liquid-gas volume flow introduced into the coarse separation unit is initially directed at a comparatively high speed.
- Further embodiments of coarse separators are, for example, cyclone separators or knitted fabrics, for example wire mesh.
- the liquid-gas volume flow, from which liquid has already been separated in the coarse separation unit, can then be passed on to the fine separation unit.
- the fine separation unit has, for example, a coalescence filter as a fine separator, on the outlet side of the liquid-gas volume flow liquid is in turn separated.
- the coarse separation unit and the fine separation unit do not necessarily have to differ in the type of coarse and fine separator in question.
- a multi-stage separation can also have identical or at least similar separation units, the term coarse separation unit then referring to the fact that here, compared to the fine separation unit, even larger quantities of liquid are contained in the liquid-gas volume flow.
- the separation units are therefore passed through in series, with the proportion of the amount of liquid in the liquid-gas volume flow decreasing sequentially, i.e. from the coarse separation unit to the fine separation unit.
- At least one liquid removal device is provided in both the coarse separation unit and the fine separation unit, which is arranged in a dripping direction related to the respective separator for collecting the separated liquid.
- At least one liquid withdrawal channel is provided, which extends from the respective liquid withdrawal device in at least a first drainage direction.
- This first drainage direction can, for example, be directed downwards in the direction of the gravitational force in order to be able to safely drain the liquid first due to gravity.
- the further course of the respective liquid withdrawal channel can then deviate from the first derivation direction.
- the at least one liquid removal channel can be designed as a return channel which returns the separated liquid into a liquid reservoir for further use and/or processing.
- the separated oil can be fed back into a screw block of an oil-lubricated screw compressor.
- the at least one liquid removal channel is formed in the liquid separation device, so that the liquid is guided within the liquid separation device. Since external liquid lines can be dispensed with, at least in the area of the liquid separation device, a more compact design is made possible by internal liquid routing.
- the at least one liquid removal channel is also protected from external influences by the liquid separation device. Likewise, components arranged in the at least one liquid removal channel, such as a backflow prevention device and/or nozzle described later, can be protected in order not to freeze, for example. In addition, the effort involved in maintenance can be reduced because no or fewer external lines have to be dismantled before maintenance.
- the at least one liquid removal channel is formed by a housing of the liquid separation device. Accordingly, the at least one liquid removal channel can be formed directly during the production of the housing of the liquid separation device. For example, the at least one liquid removal channel can be taken into account as a casting when producing the housing of the liquid separation device. Alternatively or additionally, the at least one liquid removal channel can be formed by bores.
- the at least one liquid removal channel is at least designed such that it has two channel sections, of which the at least one channel section is fluidly connected to the liquid removal device of the coarse separation unit and the at least one other channel section is fluidly connected to the liquid removal device of the fine separation unit.
- the separated liquids from the coarse separation unit and the fine separation unit are brought together via the channel sections in a liquid removal channel.
- the liquid separation device has at least two liquid removal channels, of which the at least one liquid removal channel is fluidly connected to the liquid removal device of the coarse separation unit and the at least one other liquid removal channel is fluidly connected to the liquid removal device of the fine separation unit.
- a separate liquid removal channel is provided for the coarse separation unit and the fine separation unit.
- each of the at least two channel sections or in each of the at least two liquid removal channels at least one backflow prevention device is arranged.
- the backflow prevention device is configured to prevent backflow from the at least two channel sections or the at least two liquid channels into the respective liquid removal device connected thereto.
- the backflow prevention device can be designed, for example, as a check valve.
- the at least one backflow prevention device is arranged in each of the at least two channel sections or in each of the at least two liquid removal channels.
- the backflow prevention device that can be assigned to one of the at least two channel sections or to one of the at least two liquid removal channels has a different response behavior than the backflow prevention device that can be assigned to the other of the at least two channel sections or the other of the at least two liquid removal channels.
- different pressure conditions can prevail in the coarse separation unit and the fine separation unit.
- the corresponding backflow prevention device can be adapted to the prevailing pressure conditions.
- the respective backflow prevention devices of the coarse separation unit and the fine separation unit such as corresponding check valves, can also be designed the same. This can reduce the number of different components to be installed and the risk of incorrect installation.
- At least one nozzle is arranged in the at least one liquid removal channel or is formed at least in sections through the liquid channel. Since not only the separated liquid but also gas can be derived from the respective separation unit via the at least one liquid removal channel, corresponding gas losses and thus a reduction in the efficiency of the compressor system can occur.
- the liquid or liquid-gas volume flow potentially still containing the gas can be throttled through the nozzle, so that the gas losses can be reduced. This applies in particular to the liquid removal channel or channel section, which leads away from the liquid removal device of the fine separation unit, since only small amounts of liquid are separated here compared to the gas.
- the nozzle can be inserted as a separate component into the at least one liquid removal channel.
- the cross section of the at least one liquid channel can also be adapted at least in sections such that a corresponding throttling is implemented over such a section. This nozzle or nozzle function is thus formed directly via the at least one liquid removal channel.
- the at least one nozzle is arranged in each of the at least two channel sections or in each of the at least two liquid removal channels, as described above.
- the nozzle that can be assigned to one of the at least two channel sections or to one of the at least two liquid removal channels has a different cross section than the nozzle that can be assigned to the other of the at least two channel sections or the other of the at least two liquid removal channels.
- the backflow prevention device is preferably arranged in front of the nozzle in the direction of discharge of the liquid.
- the at least one backflow prevention device is provided in the vicinity of the liquid removal device that can be assigned to it.
- the backflow prevention device and/or the nozzle is configured so that it can be screwed into the at least one liquid removal channel.
- the backflow prevention device and/or the nozzle can thereby be securely mounted in the at least one liquid removal channel in a simple manner.
- this enables simple replacement, for example in the event of a failure or due to a change in properties.
- the above-described arrangement or design of the respective backflow prevention device and/or nozzle enables safe and simple integration into the at least one liquid removal channel.
- the respective separation units can be reliably extracted with different pressure levels.
- Coarse separation unit on the clean side of the fine separator can be prevented or at least reduced.
- the backflow prevention device and the nozzle for the respective separation unit are formed by a common flow control device, in particular by a common flow control element.
- the flow control device can accordingly be designed as a pre-assembly group, which has both the backflow prevention device and the nozzle as individual components.
- the distances between the backflow prevention device and the nozzle must be set and checked in advance.
- individual assembly and, if necessary, testing can be dispensed with, which can reduce assembly effort.
- the flow control device can also have a common flow control element or can be designed as a flow control element that forms the functionalities of the backflow prevention device and the nozzle in a common component. The backflow prevention device can therefore be formed in the flow control element integrally with the nozzle.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device of the fine separation unit is arranged in a suitable installation of the liquid separation device below the respective associated separator, in particular in a flow-calmed area of the respective separation unit.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device of the fine separation unit is arranged in the respective separation unit in such a way that the liquid separated at the respective separator drips or flows directly into the respective liquid removal device. This can prevent at least the liquid separated in the respective separator from collecting in places from which it cannot be drained away.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device of the fine separation unit in a flow-calmed area of the respective separation unit, it can also be avoided that oil entrainment occurs due to the air flow.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device the fine separation unit has a liquid outlet to the at least one liquid removal channel, which is located at a lowest point of the at least one liquid removal device of the coarse separation unit and / or the at least one liquid removal device of the fine separation unit when the liquid separation device is installed in accordance with the intended use.
- the separated liquid is thus suctioned off at the lowest point of the at least one liquid removal device of the respective separation unit.
- riser pipes can be dispensed with. This increases process reliability during maintenance because, for example, bending of the riser pipe due to a collision with another tool can be ruled out. Since risers are usually geometrically pointed, the risk of injury due to the absence of a riser can also be reduced. Efficiency can also be increased because a long-term situation in which only air is sucked in as soon as the oil level drops below the lower edge of the suction can be avoided.
- the separated liquid can be completely sucked off, so that liquid entry into other system areas can be avoided.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device of the fine separation unit is designed as a detachable cover for attachment to the housing of the liquid separation device.
- the at least one liquid removal device of the coarse separation unit and/or the at least one liquid removal device of the fine separation unit can be removed in a simple manner for maintenance purposes and corresponding accessibility of the coarse separation unit and/or fine separation unit, without the return lines having to be dismantled in advance.
- the respective cover can, for example, be screwed into the housing, screwed on and/or otherwise attachable to or in the housing in a form-fitting and/or non-positive manner.
- the connection of the liquid outlet from the lid thus passes directly into the liquid removal channel of the housing of the liquid separation device, so that dismantling the lid separates the liquid return and reconnects the liquid return when the cover is reinstalled.
- an end assembly position can be provided, for example by screwing the cover against a stop, a corresponding drilling pattern or markings to be brought into line on the cover and the housing.
- a seal such as an O-ring, can be arranged on the liquid outlet and/or the liquid removal channel facing the liquid outlet, which covers the area between seals the liquid outlet and the liquid withdrawal channel in a fluid-tight manner. Leaks can be prevented accordingly.
- the at least one liquid removal channel is designed as a branch line or ring line.
- the branch line can be easily implemented via a hole and enables short distances.
- the at least one liquid removal channel can be designed as a ring line, for example to bridge further distances.
- the at least one liquid removal channel can also be composed of branch and ring line sections and possibly further line sections in a different form.
- the present invention relates to a compressor system comprising a compressor and a liquid separation device described above.
- the liquid separation device is arranged outside a housing of the compressor.
- the liquid separation device is therefore a liquid separation device that is external to the compressor. Consequently, the liquid separation device has its own external housing, into which the at least one liquid removal channel is integrated. The liquid is returned from the respective separation units back to the compressor or another discharge destination via the at least one liquid removal channel inside the housing of the liquid removal device.
- the at least one liquid removal channel is formed in particular by the housing wall.
- a configuration is provided in which the housing of the compressor adjoins the housing of the liquid separation device.
- the at least one liquid extraction channel adjoins a suction channel of the compressor.
- the output of the at least one liquid extraction channel can be connected directly to a corresponding input of the compressor without the need to provide additional external lines for this purpose.
- the distance from the housing of the liquid separation device to the housing of the compressor can be bridged with a very short return line. This can increase the compactness of the compressor and reduce maintenance requirements by reducing the number of components.
- further protective measures for external cables can be omitted or reduced to just a few cables.
- the present invention relates to a rail vehicle with a fluid separation device described above and/or a compressor system described above.
- the fluid separation device or the compressor system can enable low-loss, cost-effective and process-reliable liquid return, which works reliably even under demanding applications in rail vehicles.
- the requirement for high availability of rail vehicles is also supported by increasing ease of maintenance.
- Fig. 1 is a schematic representation of an exemplary embodiment of a compressor system according to the present invention.
- Fig. 1 shows a schematic representation of an exemplary embodiment of a compressor system 1 according to the present invention.
- the compressor system 1 includes a compressor 10 with a housing 10a and a liquid separation device 20 with a housing 20a.
- the housing 10a of the compressor borders directly on the housing 20a of the Liquid separation device 20.
- the compressor system 1 in the present configuration can also be referred to as a compressor system with a compressor and an external liquid separation device.
- the compressor 10 is an oil-lubricated screw compressor for producing compressed air.
- the liquid separation device 20 is an oil separation device.
- the medium to be compressed may also be a gas other than air and the liquid is not limited to oil for lubrication and/or cooling.
- the liquid separation device 20 comprises a coarse separation unit 21 with a coarse separator 21a and a fine separation unit 22 with a fine separator 22a.
- the coarse separator 21a is designed as a baffle plate and the fine separator 22a is designed as a coalescence filter.
- a liquid removal device 21b, 22b is arranged in each of the separation units 21, 22.
- a respective liquid removal channel 21c, 22c extends from the lowest point in the dripping direction of the liquid removal device 21b of the coarse separation unit 21 and the liquid removal device 22b of the fine separation unit 22.
- the liquid removal channel 21c of the coarse separation unit 21 drains separated liquid that has collected in the liquid removal device 21b of the coarse separation unit 21 in order to make it available to the compressor 10 again. This is done analogously for the fine separation unit 22 via the liquid removal channel 22c of the fine separation unit 22. The collection and discharge of the separated liquid takes place in a flow-calmed area, so that liquid entrainment of the already collected liquid by the flow in the respective separation unit 21, 22 is avoided.
- the respective liquid removal devices 21 b and 22 b are designed here as the cover of the respective separation unit 21, 22, which are detachably attached to the housing 20 a. The respective connection can be disconnected for maintenance purposes. Since the respective liquid outlet of the liquid extraction devices 21b and 22b is directly connected to the respective liquid extraction channels 21c and 22c formed in the housing 20a adjacent, the respective separation units 21, 22 can be opened without dismantling further bridging lines.
- the liquid removal channel 21c of the coarse separation unit 21 has a check valve 21d as a backflow prevention device at its end facing the liquid removal device 21b.
- the check valve 21b prevents liquid from flowing from the liquid extraction channel 21c back into the liquid extraction device 21b.
- a nozzle 21e is also arranged in the liquid withdrawal channel 21c.
- the liquid or liquid-gas volume flow potentially still containing the gas can be throttled through the nozzle 21 e, so that the gas losses can be reduced.
- the liquid removal channel 21c is formed here directly in the housing 20a of the liquid separation device 20.
- the training takes place here by constructing a corresponding casting as a housing 20a.
- the design of the liquid withdrawal channel 21c provides threaded sections in the area of the check valve 21d and the nozzle 21e, so that the check valve 21d and the nozzle 21e can be screwed into the liquid withdrawal channel 21c. Further downstream of the nozzle 21e, the separated liquid is fed directly to the compressor 10, here a screw block of the screw compressor, via a further section of the liquid removal channel 21c (not shown). The return line takes place within the housing 10a, 20a, so that additional external lines can be dispensed with.
- the structure of the liquid extraction channel 22c of the fine separation unit or the arrangement of a check valve 22d as a backflow prevention device and a nozzle 22e for throttling is analogous to the above statements regarding the liquid extraction channel 21c of the coarse separation unit 21.
- the respective check valves 21d differ, 22d and nozzles 21e, 22e from each other.
- the check valve 21 d and the nozzle 21 e which are assigned to the coarse separation unit 21, are adapted to the prevailing pressure level in the coarse separation unit 21 and the resulting pressure ratio.
- the check valve 22d and the nozzle 22e which are assigned to the fine separation unit 22, are adapted to the prevailing pressure level in the fine separation unit 22 and the resulting pressure ratio.
- the compressed oil-air volume flow is introduced into the coarse separation unit 21 in relation to the oil-lubricated screw compressor as compressor 10.
- the compressed oil-air volume flow hits the baffle plate as a coarse separator 21a, so that a first part of the oil from the oil-air volume flow is separated on the coarse separator 21a and drips into the liquid removal device 21b underneath.
- the oil collected in the liquid extraction device 21 b of the coarse separation unit 21 is sucked out through the liquid extraction channel 21 c of the coarse separation unit 21 via the check valve 21 d arranged in the liquid extraction channel 21 c and the nozzle 21 e also arranged therein and fed back to the screw block of the compressor 10.
- the compressed oil-air volume flow from which part of the oil has already been separated in the coarse separation unit 21, then flows from the coarse separation unit 21 into the fine separation unit 22.
- the fine separator 22a is flowed through by the compressed oil-air volume flow, which in turn causes oil separated and collected in the liquid removal device 22b of the fine separation unit 22.
- the separated oil is also suctioned and returned in the fine separation unit 22 through the liquid extraction channel 22c of the fine separation unit 22 via the check valve 22d arranged in the liquid extraction channel 22c and the nozzle 22e also arranged therein into the screw block of the compressor 10.
- the liquid extraction channel 22c of the fine separation unit 22 and liquid extraction channel 21c of the coarse separation unit 21 are combined in the housing 20a of the liquid separation device 20 to form a common liquid extraction channel (not shown) in order to supply the extracted oil to the screw block of the compressor 10 via the common liquid extraction channel.
- the liquid removal channel 22c of the fine separation unit 22 and liquid removal channel 21c of the coarse separation unit 21 can also be guided separately in the housing 20a of the liquid separation device 20 in order to only open into a common liquid removal channel in the housing 10a of the compressor or to a separate inlet in the screw block of the compressor 10 to be guided.
- the invention is not limited to the embodiment described. In particular, the features described for the embodiment, other embodiments and further developments of the invention can be combined with one another, provided they are not reasonably mutually exclusive.
