Detailed Description

The embodiment of the separating module, which is designated as a whole by 100, shown in fig. 1 to 3 is used in particular as a component of a separating device 102.

The separation module 100 is in particular one of a plurality of substantially identically designed separation modules 100, which can be arranged in a module receptacle of the separation device 102, which is configured complementary thereto. In this case, the separating module 100 can be fixed in a particularly exchangeable manner on the module receptacle.

The gas flow can be cleaned in particular by means of the separation module 100. In particular, impurities in the feed gas stream can be removed.

The separating device 102 is in particular a component of a painting installation and serves to remove paint overspray from a gas stream, in particular an air stream, which is guided through a painting booth.

The separating module 100 preferably comprises a housing 104, which is in particular substantially cuboid in shape and encloses an interior 106.

The housing 104 has an inflow side 108 and an outflow side 110.

The gas flow to be purified can flow into the inner chamber 106 through the inflow side 108. The gas stream cleaned in the interior 106 can flow out of the interior 106 of the housing 104 at the outflow side 110.

A plurality of cyclonic separating elements 112 of the separation module 100 are arranged in the inner chamber 106.

The cyclonic separating elements 112 form an impact separation stage 114 of the separation module 100 on one side and a cyclonic separation stage 116 of the separation module 100 on the other side.

For this purpose, the cyclone separating elements 112 each comprise a cyclone body 118 which is arranged in an inflow section 120 of the interior 106 and around which the raw gas stream to be purified flows.

Thus, the cyclone body 118 forms in particular an impingement separation element 122.

Furthermore, the cyclone element 112 has an inlet opening 124, in particular an inlet channel 125.

In particular, the inlet passage 125 connects a cyclonic separation chamber 126 disposed within the cyclone body 118 with an ambient environment 128 of the cyclone body 118. The ambient environment 128 is in particular the inflow section 120 of the inner cavity 106.

The inlet channels 125 of the cyclone body 118 are arranged and/or configured symmetrically to each other, in particular with respect to a central axis 130, preferably with respect to an axis of symmetry 132.

In particular, the inlet passage 125 is arranged to open tangentially into the cyclone body 118.

In particular, the air inlet passage 125 is arranged and/or configured at an upper end region of the cyclone body 118 with respect to the direction of gravity g.

In order to protect the gas inlet channel 125 in particular from a direct inflow of the raw gas stream, it can optionally be provided that a baffle 127 (see fig. 2) is arranged in the inflow section 120.

The baffle 127 protrudes into the flow path of the raw material gas flow from above, for example, with respect to the direction of gravity g. In particular, the inflow opening 129 formed on the inflow side 108 can be partially covered by a flap.

The cyclone body 118 is, for example, of cylindrical sleeve-shaped, conical sleeve-shaped or truncated conical sleeve-shaped design.

In particular, the cyclone body 118 tapers downward along the gravity direction g.

Also arranged at the upper end region of each cyclone body 118 with respect to the direction of gravity g is a cyclone cover 134 defining the cyclone chamber 126 and/or an immersion tube 136 projecting into the cyclone chamber 126.

Preferably, the cyclone cover 134 and the dip tube 136 are arranged and/or configured symmetrically, in particular rotationally symmetrically, about the central axis 130 of each cyclone separating element 112.

A partition wall 138 of the housing 104, which is likewise arranged at the upper end region of the cyclone body 118, delimits the inflow section 120 upward and fluidically from an outflow section 140 of the interior 106.

A fluid connection is made via the inlet tube 136 between the cyclonic separation chamber 126 below the dividing wall 138 and the outflow section 140 above the dividing wall 138.

Thus, the raw gas stream flowing into the inflow section 120 may flow into the cyclonic separation chamber 126 through the inlet opening 124 and eventually through the dip tube 136 into the outflow section 140. The outflow section 140 is finally open at its end facing the outflow side 110, so that the cleaned gas flow can finally leave the interior 106.

Preferably, a further separation stage 142 (nachbscheidedestufe), in particular a filter element, preferably a paint protection mat, is arranged at the rear end of the outflow section 140 with respect to the flow direction.

In the embodiment of the separation module 100 shown in fig. 1 to 3, a plurality of, in particular two, inflow sections 120 and a plurality of, in particular two, outflow sections 140 assigned to the inflow sections 120 are provided.

The inflow section 120 with the cyclone separating elements 112 arranged therein and the associated outflow section 140 each form a separating layer 144 of the separating module 100.

In particular, two such separating layers 144 are provided, which are arranged one above the other, in particular with respect to the direction of gravitational force g.

The multiple separation layers 144 are preferably flowed through by the gas stream independently of one another.

In view of an optimized separation effect and in view of the lowest possible pressure loss during the flow through the separation module 100, a plurality of, for example, 14 cyclone separation elements 112 are provided at the separation module 100.

The cyclone separating elements 112 are entrained by the feed gas flowing into the inflow section 120, so that in particular the outer sides 146 of the cyclone bodies 118 which act as impact separating elements 122 form separating surfaces. In particular, impurities separated off at the outer side 146 of the cyclone body 118 can be collected by means of a collecting gutter 148 which is constructed and/or arranged below the cyclone body 118.

The chamber surrounding the cyclone body 118 is in particular the impingement separation chamber 150.

Thus, the environment 128 of the cyclone body 118 impinges particularly on the separation chamber 150.

To minimize pressure losses, the cyclonic separating elements 112 may be traversed in parallel with one another.

In addition, the air inlet passage 125 is preferably configured to create an optimized cyclonic flow within the cyclone body 118.

Furthermore, the funnel-shaped, in particular trumpet-shaped, inlet tube 136 can reduce the pressure loss during the transition to the individual outflow sections 140.

A trumpet shape is understood here to mean, in particular, a shape which extends into the pipe 136 and becomes wider and wider in the flow direction of the gas stream.

During the flow through the cyclone separating element 112, impurities are separated in particular at the inner sides 152 of the cyclone body 118, so that the respective inner side 152 also forms a separating surface.

Thus, the impurities separated during operation of the separation module 100 are mostly separated at the cyclone bodies 118 of the cyclone separating elements 112.

In particular if the impurities to be separated are flowable, for example liquid, they can flow out in the direction of gravity g and thus accumulate in particular in the collecting groove 148 of the respective separating layer 144 and/or in the bottom region of the respective cyclone body 118.

Thus, the separated impurities do not influence, or at least only to a low extent influence, the throughflow of the separation module 100.

Thus, the separation module 100 can be used to purify a feed gas stream for long periods of time.

The impurities being separated and the pressure differential may cause the components of the separation module 100 to be subjected to mechanical and/or static loads.

Therefore, a supporting element 154 (see in particular fig. 3) can be provided in particular for reinforcing the separating module 100.

The support elements 154 are arranged here, for example, in the respective outflow section 140.

Furthermore, one or more support elements 154 are preferably also arranged in the respective inflow section 120.

In particular, the cyclone bodies 118 here form support elements 154 in the respective inflow section 120.

In particular, the support element 154 can support the partition wall 138 and thus also the at least one collection trough 148 downward with respect to the direction of gravity g.

Especially when the impurities to be separated can no longer be handledOr to detach the separation module 100 in case of damage to the separation module 100, it is advantageous if the separation module 100 is a disposable product, which can be recycled especially simply and environmentally.

For example, it can be provided that the separating module 100 is completely or at least largely made of paper, cardboard or other fibrous material.

In particular, the components of the separating module 100 are preferably fiber shaped parts, which are produced by wet forming, pressing and subsequent drying.

Preferably, the components of the separation module 100, in particular the cyclone body 118, the cyclone cover 134, the immersion tube 136 and/or the partition 138, can be produced in large numbers in a simple manner and can be stacked in large numbers in a compact manner on themselves.

For example, it can be provided that the cyclone body 118 has an opening angle of at least about 8 ° or at least about 6.5 °, as a result of which, on the one hand, simple demolding during the production of the cyclone body 118 and, on the other hand, simple stacking of a plurality of cyclone bodies 118 can be achieved.

The housing 104 is preferably cardboard, which may be folded, among other things.

The plurality of separating modules 100 can therefore be transported particularly compactly in the disassembled state and can be produced in a simple manner, in particular by simple plugging together and optional additional fastening.

The alternative embodiment of the separation module 100 shown in fig. 4 differs from the embodiment shown in fig. 1 to 3 essentially in that the interior 106 comprises an inflow chamber 156 and an outflow chamber 158.

The inflow chamber 156 is contiguous with the inflow side 108 and serves to distribute the incoming raw gas flow to the plurality of inflow sections 120.

The outflow chamber 158 adjoins the outflow side 110 and serves to combine the gas flows flowing out of the outflow section 140, in particular in order to finally discharge the total purge gas flow out of the separation module 100.

In other variants of the separation module 100, only one inflow chamber 156 or only one outflow chamber 158 can also be provided.

Furthermore, the inflow chamber 156 and/or the outflow chamber 158 can be provided only for a single separation module 100, respectively, but can also be provided for a plurality of separation modules 100.

Furthermore, the alternative embodiment of the separation module 100 shown in fig. 4 is identical in terms of structure and function to the embodiment described in fig. 1 to 3, so reference is made in this respect to the description thereof.

The alternative embodiment of the separation module 100 shown in fig. 5 to 8 differs from the embodiment shown in fig. 1 to 3 essentially in that the separation module 100 comprises a plurality of rows 202 of cyclone separating elements 112 arranged in succession along the inflow direction 200, wherein the rows 202 of cyclone separating elements 112 comprise cyclone separating elements 112 having mutually different sizes.

In particular, the cyclone bodies 118 of the cyclone separating elements 112 are constructed to be different in height.

In the view shown in fig. 6 of the separation module 100, which is perpendicular and cut along the inflow direction 200, the cyclone separating elements 112 arranged in succession along the inflow direction 200 are arranged with decreasing height of the cyclone bodies 118.

The cyclone separating elements 112 arranged in succession in the inflow direction 200 form, in particular, a row 204 of cyclone separating elements 112.

The inlet tubes 136 of the cyclonic separating elements 112 are preferably constructed substantially identically for each cyclonic separating element 112.

Furthermore, substantially identically designed air inlet parts 206 of the cyclone bodies 118 are provided in each case at the cyclone bodies 118. An air inlet opening 124 (see fig. 7) is arranged and/or configured in the air inlet part 206.

Conversely, the reversing elements (Umkehrteile)208 of the cyclone body 118 preferably have different dimensions, in particular different heights.

The partition walls 138 covering the cyclone separating elements 112, in particular forming the cyclone covers 134 and preferably also the feed-through tubes 136, are preferably constructed in stages in the embodiment of the separating module 100 shown in fig. 5 to 8. In particular, a flow cross section of the outflow section 140 is thereby formed which increases along an outflow direction 210 extending parallel to the inflow direction 200, as a result of which, in particular, the flow resistance of the separation module 100 can be reduced.

Preferably, the most local screening of the air inlet opening 124 is achieved by differently sized reversal parts 208 of the cyclonic separating element 112. In particular, the inlet opening 124 projects upwards and/or downwards and/or laterally beyond the cyclone separating element 112 arranged in front thereof in the inflow direction 200, whereby the inflow into the inlet opening 124 and thus the separating effect can be optimized.

As can be gathered in particular from fig. 5 to 7, the further separating walls 138 preferably have a plurality of supporting elements 154, which are in particular designed as hollow projections, and thus can serve on the one hand to maintain the distance between the two separating walls 138 and on the other hand also to accommodate the separated impurities. In particular, the hollow support element 154 preferably serves as a container for receiving liquid impurities which are separated from the raw gas stream to be purified.

The separating wall 138 provided with the support element 154 here forms in particular a separating wall 212, on which separating wall 212 further separating layers 144, for example separating layers 144 formed by the component combinations shown in fig. 5 to 7, can be stacked.

The embodiment of the splitter module 100 shown in fig. 5 to 8 is also identical in terms of construction and function to the embodiment shown in fig. 1 to 3, so that reference is made in this respect to the above description thereof.

The alternative embodiment of the separation module 100 shown in fig. 9 differs from the embodiments shown in fig. 5 to 8 essentially in that the outflow section 140 has an at least approximately constant cross section in the outflow direction 210.

However, the cyclonic separating elements 112 are of different sizes, particularly those cyclonic separating elements 112 which are arranged in series along the inflow direction 200.

In this case, it is preferred to provide the same reversing element 208 of the cyclone body 118, but to provide the air inlet element 206 with different dimensions, in particular different heights.

In particular, the increasingly larger intake part 206 is arranged in the inflow direction 200, as a result of which the intake part 206 and the intake opening 124, which project in each case over the upstream cyclone element 112, are formed, which can contribute to an optimization of the inflow and thus to the separation.

In order to compensate for different sizes of the cyclonic separating elements 112, in particular dip tubes 136 may be provided which protrude into the interior of the cyclone body 118 at different distances.

Furthermore, the embodiment of the splitter module 100 shown in fig. 9 is identical in terms of structure and function to the embodiment shown in fig. 5 to 8, so reference is made in this respect to the above description thereof.

The further embodiment of the separating module 100 shown in fig. 10 differs from the embodiment shown in fig. 9 essentially in that the air inlet parts 206 of all the cyclone separating elements 112 are of substantially identical design, whereas the reversing elements 208, in particular the reversing elements 208 of the cyclone separating elements 112 arranged in series along the inflow direction 200, have different heights.

This also enables an optimized inflow of the inlet opening 124 and thus an optimized separation of impurities.

In the embodiment shown in fig. 10 of the separation module 100, the dip tube 136 is configured with different lengths. In particular, the immersion pipes 136 each project into the cyclone separating element 112, in particular into the cyclone body 118, so far that the immersion pipes 136 each end in the transition region between the inlet part 206 and the reversing part 208 of the respective cyclone body 118.

Furthermore, the embodiment of the splitter module 100 shown in fig. 10 is identical in terms of structure and function to the embodiment shown in fig. 9, so reference is made in this respect to the above description thereof.

In fig. 11, a schematic horizontal sectional view of an embodiment of the separation module 100 is shown, which corresponds in terms of basic structure, for example, to the embodiment shown in fig. 1 to 3, however, comprises five rows 202 and/or five rows 204 of five cyclone separation elements 112 each.

The cyclone separating elements 112 are embodied identically to one another, so that in particular the air inlet openings 124 of all cyclone separating elements 112 are arranged, for example, on the left with respect to the inflow direction 200.

As a result, an asymmetry is formed in the flow through the inflow section 120 and thus into the cyclone separation element 112, since an influenced flow can be obtained in particular in the edge region of the interior 106 facing the housing 104.

This effect can also be neglected when the number of cyclonic separating elements 112 is relatively large, for example in the embodiment shown in figure 11.

However, particularly when larger cyclone separating elements 112 and/or a smaller number of cyclone separating elements 112 are provided, the disturbance of the flow in the edge region can be very disadvantageous.

Preferably, therefore, the air inlet opening 124 is directed towards and/or associated with a flow channel 214, which is formed and/or arranged in particular between the two rows 204 of cyclone separating elements 112.

Here, each flow passage 214 is preferably bounded on two sides by the cyclonic separating element 112.

As may be gathered in particular from fig. 12, the intake opening 124 is preferably arranged not towards the housing 104 but towards the flow channel 214.

However, if, for example, as shown in fig. 12, the inlet opening 124 of one flow channel 214 is twice as large as the inlet opening 124 of the other flow channel 214, this can lead to a very uneven flow pattern and thus to an inadequate separation effect. It is therefore preferably provided, as shown in particular in fig. 13, that the flow channel 214 is provided with a uniform number of inlet openings 124. This is achieved in particular in that the cyclone separating elements 112 arranged in a row 204 in series in the inflow direction 200 have inlet openings 124 which are assigned to different flow channels 214.

In particular, homogenization can be achieved in that each flow channel 214 is provided with the same number of inlet openings 124, except for a deviation of exactly 1 caused by the geometry.

In all further illustrated embodiments of the separation module 100, the arrangement and/or orientation of the air inlet openings 124 according to the embodiment of the separation module 100 shown in fig. 13 can be provided for optimization purposes.

As can be gathered from a comparison of fig. 14 and 15, the inlet opening 124 can be configured, for example, as an inlet socket 216 (see fig. 14) or be formed by a recess in the substantially cylindrical sleeve-or conical sleeve-shaped wall of the inlet section 206 (see fig. 15).

The use of the intake connection 216 according to fig. 14 can lead to an optimized flow through within the cyclone body 118. While the use of a simple recess in the air inlet part 206 according to fig. 15 allows a particularly simple manufacture of the cyclone body 118.

The two variants of the cyclone separating elements 112 according to fig. 14 and 15 are in principle suitable for all of the described separating modules 100.

By using a separation module 100 of the type described above, it is preferably possible to reduce the production costs, the transport costs and/or the storage costs and, in addition, to achieve a separation with high separation efficiency and low pressure losses.
