    FILTER DEVICE AND PROCEDURE FOR MOUNTING AND | DISASSEMBLE SUCH FILTER DEVICE | The present invention relates to a filter device for separating a liquid mixture and a method for assembling and disassembling such a filter device.
    #10 The invention particularly relates to a filter device for separating a liquid mixture comprising a vessel configured to contain a first filter element and a housing configured to contain a second filter element, the vessel and the housing comprises connecting means for establishing a fluid connection between an outlet of the first filter element and an inlet of the second filter element, wherein the vessel and housing are assembled as a compact unit in making this fluid connection, and wherein the filter device is simple can be disassembled in the barrel and housing.
    In order to comply with legal regulations or to reuse valuable process fluids, it is in many cases required to separate contaminants from liquid waste streams in industrial processes.
    For example, before condensate from an air compressor can be discharged, oil must be separated from the water in this condensate.
    Various types of filter devices for separating liquid mixtures, for example mixtures of oil and water, are known in the art.
    A well known type of filter devices are designed as a series of vertical cylindrical columns or towers, as described for example in EP 0003859 A1, GB 2350571 A and EP 1502636 A1.
    E 2 BE2020/5420 Usually with this type of filter device the liquid to be separated is first sent through one of the vertical columns that contains a first filter element | which allows a coarse separation of a major part of liquid impurities 9 . The liquid is then passed through the other columns containing #5 further filter elements that allow finer separation.
    9 This type of filter devices has the drawback that the vertical cylindrical columns form a voluminous whole, certainly for filter devices that separate voluminous liquid mixture flows.
    For this reason, filter devices have been developed in which various components of the filter device are integrated in a more compact and elegant design.
    EP 1702660 A1, EP 2539423 A1 and EP 2600961 A1 describe a type of filter devices in which a first filter element for coarse separation of a major part of liquid contaminants from the liquid mixture! and a second filter element for fine separation of the remaining liquid contaminants from the liquid mixture! are stacked on top of each other in one filter housing.
    This type of filter device has the disadvantage that the first filter element always has to be removed before the second filter element can be serviced or replaced.
    GB 2251812 A and GB 2260133 A both disclose an apparatus for separating oil from an oil-water mixture having a first separation chamber optionally containing a coalescing filter element and a second separation chamber containing a sorption bed filter element. The first separation chamber is accommodated in a vessel, while the second separation chamber is accommodated in a housing separate from this vessel. The vessel has a recess into which the housing can be placed and wherein the vessel and housing can be placed in fluid communication by inserting the housing into the recess and they can be disengaged by removing the housing from the recess.
    { However, the recessed part of the barrel is at an elevated level in | placed in the vessel, creating a risk that the housing will be removed from | the recessed part unintentionally falls to the floor, for example when the filter element in the housing needs to be replaced, especially if the housing # is large and heavy. This makes removal of the housing from the recessed portion difficult and may result in damage to the housing and/or injuries due to manual handling.
    { 10 In addition, once the housing is removed from the recess, it is difficult to transport the housing over a long distance without the use of external aids, especially if the housing is large and heavy, which affects the ease of maintenance of the housing and/or the filter element placed in the housing.
    The object of the present invention is to provide a solution to one or more of the above and/or other drawbacks. In particular, this invention is intended to provide a filter device for separating liquid mixtures with a compact design and high serviceability, even for large-scale filter devices that handle bulky liquid mixture streams.
    The present invention for that purpose relates to a filter device for separating a liquid mixture, the filter device comprising a vessel configured to include at least one first filter element, the vessel including an inlet port for introducing the liquid mixture into the first filter element, the vessel additionally comprising a flat vessel bottom surface configured so that the vessel can stand stably on a horizontal flat base when the vessel bottom surface is parallel to and level with the horizontal flat base,
    the vessel further comprising a vessel shell surface extending from a periphery of the vessel bottom surface in a direction opposite to the vessel bottom surface, the filter device comprising at least one housing configured to contain at least one second filter element, the housing comprises a flat housing bottom surface configured so that the housing can stand stably on a horizontal flat base # when the housing bottom surface is parallel to and level with the horizontal flat base, 9 10 wherein the housing additionally comprises a housing jacket surface comprising extending from a periphery of the housing base in a direction opposite to the housing bottom surface, the vessel jacket surface including a recess that forms a recess configured to accommodate the housing therein, an opposite side of the housing jacket surface is configured to fit into the recess formed in the recessed portion, the recessed portion and the opposite side having connecting means for releasably bringing an outlet of the first filter element into fluid communication with an inlet of the second filter element when the opposite side of the housing shell surface is fitted into the recess formed by the recessed portion, characterized in that the recessed portion extends from the drop bottom surface, and said barrel bottom surface and the housing bottom surface are parallel to each other and in the same plane when the opposite side of the housing shell surface is in the recess formed by the recess is fitted so that the outlet of the first filter element is in fluid communication with the inlet of the second filter element.
    in this context a 'horizontal flat ground plane' is understood to mean a flat ground plane that is perpendicular to a direction in which a main gravitational force, generally the earth's pull, is exerted on the filter device. In other words, a "horizontally flat ground plane" means a flat ground plane that is oriented level.
    > BE2020/5420 | In this context, standing 'steady' means that the filter device will not wobble or tilt under the influence of a main gravitational force acting on | applied to the filter device, usually the Earth's gravity, when the #5 filter device is subjected to a force with a horizontal component. 9 In this context, a 'shell plane' means a plane extending from a full perimeter of a base plane.
    In this context, a "direction opposite to the vessel bottom surface" or a "direction opposite to the housing bottom surface" means a direction opposite to a normal of the vessel bottom surface or the housing bottom surface, respectively.
    The advantage of such a filter device according to the invention is that when the vessel bottom surface is parallel to and level with the horizontal flat base, as should be the case if the vessel is correctly positioned, and when the opposite side of the housing jacket surface is in the recess formed by the recessed portion of the vessel jacket surface is fitted, the housing may be removed from the vessel by moving it across the horizontal plane base.
    This reduces or even prevents the risk of the housing accidentally falling to the floor when removing the housing from the vessel, thereby achieving a safer situation than can be achieved with previously known filter devices. According to a preferred embodiment of the filter device according to the present invention, the housing comprises a housing top surface opposite the housing bottom surface, the housing jacket surface being located between the housing bottom surface and the housing top surface, the housing top surface sloping towards the housing bottom surface in the direction of the recess formed by the recessed portion when the opposite side of the housing jacket surface is fitted into the recess.
    ° BE2020/5420 | This makes it easier when removing the housing from the vessel 9 to tilt the opposite side of the housing jacket surface and the housing bottom surface away from the horizontal flat ground plane, while 9 allowing the vessel bottom surface to be parallel to and level with the #5 horizontal flat ground plane. and while the housing bottom surface 9 can still remain supported by the horizontal flat ground plane on the side of 9 the housing bottom surface opposite the opposing side. This means that neither the vessel nor the housing need be fully lifted from the horizontally flat ground plane to bring the housing into this tilted-away position when removing the housing from the vessel.
    By taking advantage of this option when removing the housing from the vessel, the friction between the housing bottom surface and the horizontally flat base can be reduced. This makes it easier to remove the housing from the vessel, while the housing is still stably supported by the horizontal flat base. In this way, ease of maintenance of the housing is promoted, while safe removal of the housing is guaranteed.
    According to another preferred embodiment of the filter device according to the present invention, the housing is provided with one or more wheels on a side of the housing jacket surface opposite the opposite side, wherein a periphery of the one or more wheels is tangent to an extension of the housing bottom surface.
    By 'an extension of the housing bottom surface' in this context is meant a plane in which the flat housing bottom surface is located.
    When using the option to tilt the opposite side of the housing jacket surface and the housing bottom surface away from the horizontal flat base, while the housing bottom surface always remains level with the horizontal flat base on the side of the
    / BE2020/5420 housing bottom surface opposite the opposite side when removing the housing from the vessel, the one or more wheels further reduce friction | between the housing bottom surface and the horizontal flat ground plane, giving the | simplifies removal of the housing from the barrel. | 5 # The one or more wheels also make it less strenuous to move a large and heavy housing over a long distance, facilitating maintenance 9 on the housing and/or the second filter element placed in the housing and posing a risk of injury reduced by manual handling. The one or more wheels are preferably partially recessed into the side of the housing shell surface opposite the opposing side. This makes the housing more compact.
    According to another preferred embodiment of the filter device according to the present invention, the housing is provided with a handle element on one side of the housing shell surface opposite the opposite side.
    The presence of such a handle element simplifies removal of the housing from the vessel and moving the housing over a long distance, simplifying maintenance of the housing and/or the second filter element in the housing and reducing the risk of injury if effect of manual handling.
    The handle element is preferably a re-entrant handle element. Preferably, the position of the handle element is also closer to the housing top surface than to the housing bottom surface.
    A re-entrant handle element has the advantage that there are no protruding portions of the handle element on the housing which would make the assembly of the housing and the barrel bulkier when the housing is fitted to the barrel.
    | 6 BE2020/5420 | If the recessed handle element is closer to the housing top face than the housing bottom surface, the / recessed handle element can assist a manual user in tilting the opposite side of the housing shell surface and the # housing bottom surface from the horizontal flat ground plane when removing 9 from the housing from the barrel. In this case, the manual user also does not have to bend 9 too deeply when removing the housing from the vessel, which reduces the risk 9 of injuries during manual handling. According to another preferred embodiment of the filter device according to the present invention, the filter device comprises two or more housings. In this way, the total volume and weight of the second filter elements placed in the two or more housings are distributed among these two or more housings. This makes each of the two or more housings lighter, which improves serviceability for each of the two or more housings and reduces the risk of manual handling injuries when removing the two or more housings from the vessel.
    Preferably, the two or more housings are provided with one or more connecting conduits configured such that the liquid mixture can flow from the at least one second filter element in one of the two or more housings to the at least one second filter element in another of the two or more housings. the two or more housings. More preferably, the one or more connecting lines are flexibly and releasably connected to the two or more housings. In this way, the second filter elements in the two or more housings can be connected in series so that they can cooperate in separating liquid contaminants from the liquid mixture.
    A conduit that is flexible and releasably connected to the two or more housings can be easily removed from the housings and | be replaced, for example at the same time as performing maintenance or replacement of the second filter elements. | # According to another preferred embodiment of the filter device 9 according to the present invention, the first filter element is a coalescing filter element.
    The first filter element may perform a first coarse separation of a major portion of liquid contaminants from the liquid mixture, thus providing protection for the second filter element which may be more expensive and more sensitive to saturation than the first filter element.
    The coalescing filter element is preferably made of a plastic foam, preferably comprising nonwoven polypropylene fibers or borosilicate glass microfibers.
    Such a plastic foam offers a large internal surface on which liquid contamination droplets can coagulate.
    Nonwoven polypropylene fibers or borosilicate glass microfibers are particularly suitable as filter material for separating oil droplets from an oil-water mixture.
    According to another preferred embodiment of the filter device according to the present invention, the second filter element is a sorption bed filter element.
    Preferably, the sorption bed filter element is selected from a group consisting of an activated carbon filter element, an organic clay filter element, an activated alumina filter element, a zeolite filter element or a hydrophobic polyurethane foam filter element.
    The sorption bed filter element allows a finer separation of liquid | contaminants from the liquid mixture.
    # Activated carbon, organic clay, active aluminum oxide, zeolite and 9 5 hydrophobic polyurethane foam are particularly well suited as filter media! # for separating oil from an oil-water mixture containing only a small amount of oil.
    According to another preferred embodiment of the filter device 10 according to the present invention, the vessel is provided with a removable lid.
    In this way the first filter element in the vessel is easily accessible without having to remove the housing and the second filter element placed in the housing. Therefore, maintenance or replacement of the first filter element can be easily performed by simply removing the lid from the vessel.
    According to another preferred embodiment of the filter device according to the invention, the connecting means comprise: an outlet conduit from the vessel, which outlet conduit has an outlet end which is attached to the recessed part and faces the opposite side of the housing jacket surface when the opposite side of the housing jacket surface is in the recess is appropriate; and an inlet conduit of the housing, the inlet conduit having an inlet end attached to and projecting from the opposite side of the housing jacket surface and which opposes the outlet end of the outlet conduit of the vessel when the opposite side of the housing jacket surface is fitted into the recess, wherein the outlet end and the inlet end are configured to be leak-tight when the opposite side of the housing jacket surface is fitted into the recess.
    In this way, a fluid communication between the outlet of the first filter element and the inlet of the second filter element can be achieved in a
    9 directly and simply by means of a push fit of the inlet end of the inlet pipe into the internal channel of the outlet pipe. | Preferably, an internal channel of the outlet conduit has an inward | 5 converging tapered portion at the outlet end. 9 In this way the inlet end of the inlet pipe can be easily | positioned and guided into the internal channel of the exhaust line.
    In addition, an O-ring is preferably provided around the inlet end.
    This simplifies and guarantees a good seal between the inlet end of the inlet pipe and the internal channel of the outlet pipe.
    More preferably, the inlet end is provided with a stepped portion adapted to accommodate the O-ring.
    This stepped portion prevents the O-ring from being displaced relative to the inlet end of the inlet conduit when the inlet conduit is fitted and pushed into the internal channel of the outlet conduit.
    According to another preferred embodiment of the filter device according to the present invention, the vessel and/or housing is made of a thermoplastic material, preferably low density polyethylene.
    Thermoplastic materials, and especially low density polyethylene, are generally lightweight materials. By using such materials, the weight of the vessel and/or housing can thus be reduced, which improves the ease of maintenance of such filter device components, especially with large filter devices.
    According to a further preferred embodiment of the filter device according to the present invention, the vessel and/or housing is made using a rotational molding process.
    In this way a vessel and/or housing can be seamless | produced using a standard casting process. Since a barrel | and/or housing may break due to mechanical stresses along a seam, # 5 a vessel and/or housing constructed seamlessly may be considered 9 to be resistant to mechanical stress. # According to another preferred embodiment of the filter device 9 according to the present invention, the vessel is provided with a drain valve.
    The drain valve can be used when it would be necessary to empty the vessel during use of the filter device, which has the advantage that the potentially heavy vessel does not have to be lifted and/or tilted for emptying.
    Preferably, the drain valve is provided on a side of the vessel shell surface opposite the recessed portion.
    In this way, the drain valve is easily accessible without removing the housing from the recess formed by the recess.

Figure 1 comprises a filter device 1 for separating a liquid mixture according to the invention.
    Filter device 1 comprises a vessel 2 with at least one first filter element and a housing 3 with at least one second filter element.
