Description

Title of the invention: Air / particle separation device comprising a rotating filter made of cellular material

[0001] The present application relates to an air / particle separation device comprising a rotating filter made of cellular material.

[0002] The air leaving certain equipment must be treated to remove particles such as oil, lubricant or hydrocarbon particles, for example, so that it is as pure as possible.

[0003] According to an embodiment visible in [Fig.l], a cyclonic type air / particle separation device comprises a tank 10 having a charged air inlet 12, a treated air outlet 14 and a particle outlet 16.

[0004] The tank 10 comprises a cylindrical side wall 10.1 as well as lower and upper walls 10.2, 10.3 closing the cylindrical side wall 10.1. According to one configuration, the tank 10 comprises at least one internal partition 10.4 cylindrical and coaxial with the cylindrical side wall 10.1.

[0005] The particle outlet 16 is positioned at the level of the lower wall 10.2.

[0006] According to one configuration, the charged air inlet 12 and the treated air outlet 14 are positioned respectively at the level of the cylindrical side wall 10.1 and the upper wall 10.3. The charged air inlet 12, the treated air outlet 14 as well as the inner partition 10.4 are arranged so that the air flow 18 circulates inside the tank 10 in a swirling manner. This swirling air flow 18 causes, by centrifugation, the separation of the air and the particles present in the air which are projected against the cylindrical side wall 10.1 and the inner partition 10.4 and flow down to be collected in the lower part of the tank 10.

[0007] A cyclonic separation device can be attached to an air duct outside the equipment generating this particle-laden air, which facilitates its installation and maintenance.

[0008] However, such a cyclonic type air / particle separation device is not suitable for treating large air flow rates of several hundred liters per minute.

[0009] The present invention aims to remedy all or part of the drawbacks of the prior art.

[0010] To this end, the invention relates to an air / particle separation device comprising a container as well as a charged air inlet, a treated air outlet and a particle outlet opening into the container.

[0011] According to the invention, the air / particle separation device comprises a rotary filter positioned in the container, between the loaded air inlet and the treated air outlet, the container being configured to channel air loaded with particles through the rotary filter, said rotary filter comprising at least one block of cellular material configured to be crossed by the loaded air.

[0012] The rotation of the rotary filter promotes the separation of air and particles present in the charged air, the migration of the separated particles towards the periphery of the rotary filter and their ejection from the rotary filter thanks to a centrifugal effect. This solution makes it possible to treat a greater flow of charged air than the cyclonic type air / particle separation devices of the prior art.

[0013] According to another characteristic, the container comprises at least one cylindrical side wall having an axis of revolution oriented in a vertical axial direction, the rotary filter being configured to pivot around a pivot axis coaxial with the cylindrical side wall of the container.

[0015] According to another characteristic, the rotary filter comprises an inner cylindrical face oriented towards the pivot axis. In addition, the air / particle separation device comprises a motorization as well as a pivot shaft having an axis coincident with the pivot axis and connected to the motorization, the rotary filter being positioned around the pivot shaft and connected to the latter.

[0016] According to another characteristic, the inner cylindrical face has an inner diameter substantially equal to the outer diameter of the pivot shaft.

[0017] According to another characteristic, the pivot shaft is hollow and comprises passage orifices configured to communicate the inner cylindrical face of the rotary filter, the interior of the pivot shaft and the treated air outlet.

[0018] According to another characteristic, the air / particle separation device comprises an upstream transverse wall connected to the pivot shaft as well as a downstream transverse wall connected to the pivot shaft and separated from the upstream transverse wall by a distance substantially equal to or slightly less than a distance separating the upstream and downstream faces of the rotary filter.

[0019] According to another characteristic, each of the upstream and downstream transverse walls comprises a circular peripheral edge, having a diameter substantially equal to or slightly greater than the diameter of the peripheral face of the rotary filter, as well as at least one opening passing through it.

[0020] According to another characteristic, the air / particle separation device comprises a cylindrical peripheral wall connecting the peripheral edges of the upstream and downstream transverse walls and having a diameter substantially equal to or slightly greater than the diameter of the peripheral face of the rotary filter, the cylindrical peripheral wall comprising at least one opening passing through it, the pivot shaft, the upstream and downstream transverse walls as well as the cylindrical peripheral wall delimiting an annular housing secured to the pivot shaft and configured to house the rotary filter.

[0021] According to another characteristic, the air / particle separation device comprises an interior partition, positioned in the container, which separates an upstream interior zone located in the container, between the charged air inlet and the rotary filter, into a central zone configured to channel the charged air towards the rotary filter as well as a peripheral zone located between the interior partition and the side wall and configured to collect the particles, the charged air inlet communicating with the central part, the particle outlet communicating with the peripheral zone.

[0022] According to another characteristic, the particle outlet opens into the lower part of the peripheral zone.

[0023] According to another characteristic, the container comprises at least one cylindrical side wall. In addition, the partition is substantially cylindrical, coaxial with the side wall and extends between a first end connected to the container and a second end slightly spaced from the rotary filter.

[0024] According to another characteristic, the container comprises at least lower and upper parts, the lower part comprising a side wall section and a lower transverse wall, the upper part comprising a side wall section and an upper transverse wall, the lower and upper parts being configured to cooperate in order to form a closed enclosure when they are assembled.

[0026] Other characteristics and advantages will emerge from the description of the invention which follows, a description given by way of example only, with reference to the appended drawings, among which:

[0027] [Fig.l] is a schematic representation of an air / particle separation device illustrating an embodiment of the prior art,

[0028] [Fig.2] is a schematic representation of an air / particle separation device illustrating an embodiment of the invention,

[0029] [Fig.3] is a perspective section of an air / particle separation device illustrating one embodiment of the invention.

[0030] According to one embodiment, an air / particle separation device 20 comprises a container 22, a charged air inlet 24 opening into the container 22, a treated air outlet 26 which opens into the container 22 as well as a particle outlet 28 which opens into the container 22.

[0031] This air / particle separation device 20 is configured to treat a charged air 30 containing particles 32 such as oil, lubricant, hydrocarbon or other particles. These particles 32 contained in the charged air 30 have a higher density than the treated air 34 (uncharged). Generally, these particles 32 are liquid.

[0032] According to one application, an installation comprises at least one piece of equipment emitting a flow of charged air, at least one pipe in which the flow of charged air leaving the equipment circulates, as well as at least one air / particle separation device 20 positioned, outside the equipment, between two sections of the pipe. The air / particle separation device 20 being positioned outside the equipment generating the air charged with particles, its installation and maintenance are easier.

[0033] The air / particle separation device 20 comprises a rotary filter 36 positioned in the container 22 between the charged air inlet 24 and the treated air outlet 26, the container 22 being configured to channel the charged air 30 through the rotary filter 36.

[0034] The rotary filter 36 is configured to allow the charged air 30 to pass through it in order to separate the particles 32 from the charged air 30 and allow them to migrate, by a centrifugal effect, to the periphery of the rotary filter 36. According to one embodiment, the rotary filter 36 comprises at least one block of cellular material configured to allow the charged air 30 to pass through it. By cellular material, we mean any porous material, such as foam for example, comprising cells. According to one configuration, the rotary filter 36 comprises at least one block of metallic cellular material. For example, the cellular material is made of aluminum alloy and has open cells. Of course, the invention is not limited to these embodiments for the rotary filter 36.

[0035] According to one embodiment, the container 22 comprises at least one side wall 22.1 having an axis of revolution A22 oriented in an axial direction. In addition, the container 22 comprises lower and upper transverse walls 22.2, 22.3 delimiting with the side wall 22.1 an interior zone of the container 22. According to one arrangement, the axial direction is substantially vertical.

[0036] In the interior zone of the container 22, the flow of charged air 30 moves from upstream to downstream, between the charged air inlet 24 and the treated air outlet 26. The rotary filter 36 separates the interior zone into an upstream interior zone ZIA located between the rotary filter 36 and the charged air inlet 24 as well as a downstream interior zone ZIA' located between the rotary filter 36 and the treated air outlet 26.

[0037] According to an embodiment visible in [Fig. 3], the container 22 is made in at least two parts and comprises a lower part 40 comprising a section of the side wall 22.1 and the lower transverse wall 22.2 as well as an upper part 42 comprising a section of the side wall 22.1 and the upper transverse wall 22.3, the lower and upper parts 40, 42 being configured to cooperate in order to form a closed enclosure when they are assembled. According to one configuration, the lower part 40 comprises a first cylindrical wall 40.1 having an internal diameter D40.1. The upper part 42 comprises a second cylindrical wall 42.1, a third cylindrical wall 42.2 having an external diameter D42.2 substantially equal to the internal diameter D40.1 of the first cylindrical wall 40.1 as well as a transverse wall 42.3 connecting the second and third cylindrical walls 42.1, 42.3.The first and third cylindrical walls 40.1, 42.3 are configured to fit into each other. The transverse wall 42.3 has an outer diameter D42.3 greater than the outer diameter D42.2 of the third cylindrical wall 42.2. Thus, when the first and third cylindrical walls 40.1, 42.3 are fitted into each other, the first cylindrical wall 40.1 is in contact with the transverse wall 42.3.

[0038] According to one arrangement, the air / particle separation device 20 comprises a seal 44 interposed between the first and third cylindrical walls 40.1, 42.3.

[0039] Of course, the invention is not limited to this embodiment for the container 22. According to embodiments, the container 22 comprises at least one cylindrical side wall 22.1 having a given internal diameter.

[0040] According to an arrangement visible in [Fig.3], the charged air inlet 24 is positioned at the level of the side wall 22.1, between the lower transverse wall 22.2 and the rotary filter 36. The treated air outlet 26 is positioned at the level of the side wall 22.1, between the upper transverse wall 22.3 and the rotary filter 36.

[0041] The rotary filter 36 is configured to pivot about a pivot axis A36 oriented in the axial direction and substantially coaxial with the cylindrical side wall 22.1 of the container 22. When the axial direction is vertical, the pivot axis A36 is substantially vertical. According to one embodiment, the air / particle separation device 20 comprises a pivot shaft 46 having an axis coincident with the pivot axis A36, a pivoting connection 48 connecting the pivot shaft 46 and the container 22 as well as a motorization 50 secured to the container 22 and having an output shaft connected to the pivot shaft 46. According to a configuration visible in [Fig. 3], the pivoting connection 48 comprises two bearings 48.1, 48.2 positioned on either side other of the rotary filter 36, in two substantially horizontal planes. According to one arrangement, the first bearing 48.1 is interposed between the second cylindrical wall 42.1 and the pivot shaft 46. In addition, the second bearing 48.2 is interposed between the lower transverse wall 22.2 and the pivot shaft 46.

[0042] According to one embodiment, the motorization 50 is located outside the container 22 and connected to the upper transverse wall 22.3.

[0043] The pivot shaft 46 extends from the first lower transverse wall 22.2 to the second upper transverse wall 22.3.

[0044] Of course, the invention is not limited to these embodiments for the pivot shaft 46, the pivoting connection 48 and the motorization 50. According to a simplified variant visible in [Fig.2], the air / particle separation device 20 comprises a motorization 50 secured to the container 22 as well as a pivot shaft 46 connected to the motorization 50, the rotary filter 36 being positioned around the pivot shaft 46 and connected to the latter.

[0045] According to one mode of operation, the rotary filter 36 is configured to pivot at a rotation speed greater than 8000 rpm.

[0046] According to one embodiment, the rotary filter 36 has an upstream face 36.1 substantially perpendicular to the pivot axis A36 and oriented towards the charged air inlet 24, a downstream face 36.2 substantially perpendicular to the pivot axis A36 and oriented towards the treated air outlet 26 as well as a peripheral face 36.3, connecting the upstream and downstream faces 36.1, 36.2, substantially coaxial with the pivot axis A36, said peripheral face being oriented towards the side wall 22.1 of the container 22 and having a diameter smaller than the internal diameter of the side wall 22.1. According to this embodiment, the charged air 30 enters the rotary filter 36 via its upstream face 36.1 and the particles are ejected from the rotary filter 36 by the centrifugal effect via the peripheral face 36.3.

[0047] According to one configuration, the rotary filter 36 comprises an inner cylindrical face 36.4 oriented towards the pivot axis A36.

[0048] According to an embodiment visible in [Fig. 3], the rotary filter 36 has a ring shape with a constant square or rectangular section around the pivot axis A36. The inner cylindrical face 36.4 has an inner diameter substantially equal to the outer diameter of the pivot shaft 46.

[0049] The rotary filter 36 is immobilized in translation in the axial direction relative to the pivot shaft 46. According to one embodiment, the air / particle separation device 20 comprises an upstream transverse wall 52 connected to the pivot shaft 46 as well as a downstream transverse wall 54 connected to the pivot shaft 46 and separated from the upstream transverse wall 52 by a distance substantially equal to or slightly less than the distance separating the upstream and downstream faces 36.1, 36.2 of the rotary filter 36. operation, the rotary filter 36 is positioned between the upstream and downstream transverse walls 52, 54 and immobilized between the latter. Each of these upstream and downstream transverse walls 52, 54 has a circular peripheral edge 52.1, 54.1 having a diameter substantially equal to or slightly greater than the diameter of the peripheral face 36.3 of the rotary filter 36. According to one configuration, the air / particle separation device 20 comprises a cylindrical peripheral wall 56 connecting the peripheral edges 52.1, 54.1 of the upstream and downstream transverse walls 52, 54 and having a diameter substantially equal to or slightly greater than the diameter of the peripheral face 36.3 of the rotary filter 36.Thus, the air / particle separation device 20 comprises an annular housing 58, integral with the pivot shaft 46, delimited by the upstream and downstream transverse walls 52, 54, the pivot shaft 46 as well as the cylindrical peripheral wall 56 and configured to house the rotary filter 36 and immobilize it relative to the pivot shaft 46.

[0050] The upstream transverse wall 52 comprises at least one first opening 52.2, to allow the charged air 30 to pass through it in order to enter the rotary filter 36, configured to communicate the charged air inlet 24 and / or the upstream interior zone ZIA of the container 22 with the interior of the annular housing 58. The number, shapes, arrangement and dimensions of the first opening(s) 52.2 are determined to allow the greatest possible flow of air passing through the upstream transverse wall 52.

[0051] The cylindrical peripheral wall 56 comprises at least one second opening 56.1 to allow the particles 32 to pass through it in order to be ejected from the rotary filter 36. The number, shapes, arrangement and second dimensions of the second opening(s) 56.1 are determined to facilitate the ejection of the particles 32 from the rotary filter 36.

[0052] According to one configuration, the downstream transverse wall 54 comprises at least one third opening 54.2, to allow the treated air 34 leaving the rotary filter 36 to pass through it, configured to communicate the interior of the annular housing 58 with the treated air outlet 26 and / or the downstream interior zone ZIA' of the container 22. The number, shapes, arrangement and dimensions of the third opening(s) 54.2 are determined to obtain the greatest possible flow rate of air passing through the downstream transverse wall 54.

[0053] According to one embodiment, the pivot shaft 46 is hollow and comprises at least one first passage orifice 46.1, which allows the treated air 34 leaving the rotary filter 36 to penetrate inside the pivot shaft 46, configured to communicate the interior of the annular housing 58 with the interior of the pivot shaft 46. The number, shapes, arrangement and dimensions of the first passage orifice(s) 46.1 are determined to obtain an outgoing air flow rate of the rotary filter 36 and entering the pivot shaft 46 as much as possible.

[0054] The pivot shaft 46 also comprises at least one second passage orifice 46.2, allowing the treated air 34 to exit the pivot shaft 46, configured to communicate the interior of the pivot shaft 46 with the treated air outlet 26 and / or the downstream interior zone ZIA'. The number, shapes, arrangement and dimensions of the second passage orifice(s) 46.2 are determined to obtain the greatest possible flow rate of air exiting the pivot shaft 46.

[0055] The invention is not limited to the embodiment visible in [Fig. 3]. In the presence of a hollow pivot shaft 46, the latter comprises passage orifices 46.1, 46.2 configured to communicate the inner cylindrical face 36.4 of the rotary filter 36, the interior of the pivot shaft 46 and the treated air outlet 26.

[0056] The air / particle separation device 20 is configured to cause the treated air 34 to exit the rotary filter 36 via at least one face among the downstream face 36.2 and the inner cylindrical face 36.4. According to the variants, the treated air 34 exits only from the downstream face 36.2, only from the inner cylindrical face 36.4 or from the downstream face 36.2 and the inner cylindrical face 36.4, as illustrated in [Fig. 3].

[0057] According to one embodiment, the air / particle separation device 20 comprises an inner partition 60 positioned in the container 22 and configured to channel the charged air 30 towards the rotary filter 36 and more particularly its upstream face 36.1. This inner partition 60 is positioned in the upstream inner zone ZIA. It is substantially cylindrical, coaxial with the side wall 22.1, spaced from said side wall 22.1 and extends between a first end 60.1 connected to the container 22, more particularly to the lower transverse wall 22.2, and a second end 60.2 slightly spaced from the rotary filter 36, more particularly from its upstream face 36.1. In the presence of an upstream transverse wall 52, the second end 60.2 of the interior partition 60 is slightly spaced from the upstream transverse wall 52. By slightly spaced, we mean the distance separating the second end 60.2 of the interior partition 60 and the upstream transverse wall 52 or the upstream face 36.1 is of the order of a few millimeters, less than 10 mm and preferably less than 5 mm.

[0058] According to one arrangement, the inner partition 60 has a diameter less than or equal to the diameter of the peripheral face 36.3 of the rotary filter 36 or of the cylindrical peripheral wall 56 of the annular housing 58.

[0059] The inner partition 60 separates the upstream inner zone ZIA into a central zone 62 configured to channel the charged air 30 towards the rotary filter 36 and a peripheral zone 64, located between the inner partition 60 and the side wall 22.1, configured to collect the particles 32, the charged air inlet 24 communicating with the central part 62, the particle outlet 28 communicating with the peripheral zone 64. According to one arrangement, the particle outlet 28 opens into the lower part of the peripheral zone 64 to allow an exit by gravity of the parts of the container 22.

[0060] According to one configuration, the interior partition 60 is spaced from the side wall 22.1 by a distance of between 5 and 20 mm.

[0061] In the presence of an interior partition 60, the air / particle separation device 20 may comprise at least one pipe 66 configured to communicate the charged air inlet 24 and the central zone 62.

[0062] The operating principle of the air / particle separation device 20 is as follows.

[0063] The air / particle separation device 20 is positioned on a pipe in which a forced air flow flows from upstream to downstream. Thus, the charged air 30 enters the air / particle separation device 20 via the charged air inlet 24 and leaves said device via the treated air outlet 26.

[0064] The charged air 30 entering the air / particle separation device 20 then passes through the rotary filter 36 by entering through its upstream face 36.1 and exiting via the downstream face 36.2 and / or the inner cylindrical face 36.4. In the rotary filter 36, the particles 32 are extracted from the charged air 30 which leaves the rotary filter 36 in the treated state. The rotation of the rotary filter 36 promotes the separation of the particles 32 from the charged air 30 and the extraction of the particles 32 from the rotary filter 36 which migrate, thanks to the centrifugal effect, towards the periphery of the rotary filter 36. This solution makes it possible to treat a flow rate of charged air greater than the cyclonic type air / particle separation devices of the prior art.
