Definitions
- Container for holding a fluid
- the invention relates to a container for receiving a fluid, in particular a stirred container, comprising: a wall which defines a receiving space for the fluid and is enamelled on a surface facing the fluid, an installation element which is arranged in the receiving space and on a surface facing the fluid Outer surface is enamelled.
- baffles inside the container in order to additionally influence the movement of the fluids generated by the stirring devices, in particular to disturb a pure rotation of the entire amount of fluid in the container by the stirrer in such a way that a real mixing of the fluids and a mixing of the components and reaction products with one another is effected.
- baffles are often designed as flat metal sheets that are located inside the container and have a shape that is intended to facilitate their installation and at the same time ensure the most effective possible mixing of the fluid in the container.
- a common way of arranging and fastening built-in elements, such as measuring probes, fluid supply or discharge lines or baffles inside the container, is to guide the built-in element through a passage, for example of the type described above, and to let it protrude into the interior. Fastening then typically takes place on the outside of the opening by means of a flange connection.
- a flange connection Such a solution is described, for example, in DE 20 2008 009 252 U1.
- Fastening via a passage and a flange connection has the disadvantage that the enamel layer cannot be continuous in the area of the passage or the flange connection. Rather, a gap remains, which must be sealed separately. This can have a negative effect on the corrosion protection.
- the problem is countered, among other things, by the fact that the passage and the flange connection are arranged on a cover section of the container and thus the gap there generally does not come into direct contact with the liquid in the container. Nevertheless, gases can reach the gap. This also creates space needed on the lid, which is typically tight there. This is because further built-in elements are often arranged or fastened on the cover section.
- US Pat. No. 7,607,821 B2 describes in various embodiments a container of the type mentioned at the outset, in which a baffle is attached to a side wall of the container by a welded connection.
- the baffle includes a cavity through which a cooling fluid can flow.
- a through connection is provided between an interior space of the baffle and an area outside the side wall. This means that no space is occupied by the baffles on the lid and the welded connection allows continuous enamelling.
- the embodiments described in this document have the disadvantage, among other things, that the baffle is arranged suboptimally in terms of the strength of the connection, since the baffle develops a relatively large leverage effect in connection with the flow load from the stirred liquid.
- connection Due to the arrangement of the connection on the bottom section, it is located in an area of the receiving space of the container in which a strong flow is typically to be expected if the liquid is stirred. Typically, an agitator is also placed in the vicinity of the bottom section, which also contributes to the fact that the flow is typically particularly strong in the vicinity of the bottom section. Thus, essentially, a shearing load acts on the connection, but such a shearing load can be endured relatively well by the connection.
- the built-in element preferably extends over a certain length, starting from the connection, upwards into the receiving space. This creates a lever for the force of the flow, which results in a bending load on the connection.
- the bending stress is relatively small because the flow tends to be less strong higher up in the receiving space, so the lever effect is not as strong.
- fastening on the bottom allows the built-in element to be positioned at a greater distance from the side wall and thus relatively far in the middle, again due to leverage effects.
- the flow velocity also decreases with decreasing radius in relation to the central axis, there is an additional reduction in the load acting on the connection.
- a torsional load on the connection is also particularly low, since on the one hand only relatively small torsional forces are exerted by the flow on the built-in element and on the other hand only small leverage effects are to be expected in relation to the connection.
- the loads on the connection also depend on the specific shape of the built-in element. Nevertheless, the advantageous design and arrangement of the connection according to the invention allows a very free and advantageous design of the built-in element and leads to the advantages in the load scenario, at least as a tendency.
- connection in terms of its height—is arranged essentially exactly where it is highest flow load is to be expected.
- the design of the built-in element is relatively free even without a particularly solid connection.
- the built-in element can be designed with a relatively large length without jeopardizing the connection.
- An upper end of the mounting member may preferably be located above a stirring blade of a stirring device of the container.
- an upper end of the built-in element can be arranged, for example, above a vertical center of the container.
- an integral connection can in principle be configured much more easily in terms of fluid dynamics such that its flow resistance or the force resulting from the flow on the connection is relatively low.
- the connection can easily be given a rounded or beveled shape. In particular, this reduces the above-mentioned shear load on the connection.
- the advantage of the good fluid dynamic design has an effect particularly in the area of the strongest flow, typically in the vicinity of the bottom section.
- connection or a connection area between the base section and the built-in element can also be designed in such a way that their bending resistance moment is higher tangentially to the direction of flow than perpendicular to it (radial direction), i.e. the connection or the connection area can be designed "to suit the load".
- connection on the ground on the one hand and the design of the connection as an integral connection on the other hand result in the synergetic effect that the connection is subjected to a particularly low and favorable load.
- a high level of stability can thus be achieved with little use of material and the built-in element can be designed relatively freely, in particular relatively long towards the top.
- the built-in elements in particular as baffles, can be arranged relatively far in the middle and made relatively large, which results in a strong disruptive effect, but without jeopardizing the connection due to the favorable load situation.
- the length of the built-in element it should be noted that the length that is below the surface of a liquid during operation is particularly relevant for the load. Since the built-in element is fastened at the bottom, it can simply be as long as necessary, for example, that is to say it can reach up to the surface of the liquid. This proves to be particularly advantageous in comparison to an installation element which is fastened to a cover section of the container, for example by means of a passage and a flange connection. If the built-in element has to protrude into the liquid, it already has a length above the liquid surface which is additionally effective with regard to the mechanical leverage. Such a lever, which is unnecessary for the process, is eliminated to a certain extent by the invention.
- the loading benefits are not limited to substantially static loading, but extend substantially to dynamic loading as well.
- the connection is particularly less sensitive to vibration excitation due to the mechanically favorable design and arrangement.
- the material connection can also be enameled on its surface, ie a continuous enamel layer can be provided in particular between the built-in element and the wall.
- the integral connection also allows, for example in contrast to a passage with a flange connection, that there is essentially no dead space in the area of the connection. Rather, a flow and, in particular, thorough mixing of the fluid in the container is essentially ensured everywhere.
- the fact that the built-in element is fastened to the base section means that more installation space remains on the cover section for other built-in parts, such as feed lines or measuring probes.
- the container according to the invention can also be produced in a particularly simple manner.
- the built-in element can have a temperature control device, for example, such as a fluid line for a temperature control fluid.
- a temperature control device for example, such as a fluid line for a temperature control fluid.
- the temperature of the fluid in the receiving space of the container can be controlled, for example.
- container temperature control system referred to below as container temperature control system
- a double wall system or a pipe coil or half pipe coil can be used here, for example, through which a temperature control fluid flows.
- a temperature control device in the built-in element can be provided in addition to or as an alternative to a container temperature control system.
- connection also proves to be particularly advantageous for an installation element with a temperature control device.
- it makes sense to provide a passage for a tempering fluid at the connection between the built-in element and the wall.
- the connection since the connection is arranged at the bottom section, the passage is also arranged at the bottom section.
- the temperature control device of the built-in element automatically runs empty when there is no longer any pressure and associated valves are open.
- the temperature control device of the built-in element can be connected in a particularly simple manner to a container temperature control system, which is designed as a double-wall system, due to the connection arranged below.
- a double-wall system enables a relatively simple and inexpensive construction with very effective temperature control of the container, especially in comparison to a pipe coil laid around the container.
- Containers of the type in question usually have a lid section, also referred to as the top base, a cylindrical section, also referred to as the frame, and a base section, also referred to as the bottom base.
- the wall of the container referred to herein is in this case formed by the sections.
- the sections of the container are typically welded together. After joining the sections, their inner walls, which define the receiving space of the container, are enamelled.
- the built-in elements according to the invention which are integrally attached to the floor section, can advantageously also be enamelled during this process—in particular including the surface of the integral connection between the built-in element and the wall.
- a stirring device can advantageously be arranged in the receiving space of the container. This can have, for example, an agitator shaft and a plurality of agitator blades.
- the agitator shaft can be guided, for example, through a cover section of the wall of the container.
- the stirring device can for example be effective near the ground, for example only there.
- the built-in element can form a baffle, for example.
- the built-in element stands in the liquid present in the container. If the liquid is agitated, this results in a certain current disturbance effect.
- a particular advantage of the solution according to the invention is that the disruptive effect is also effective when the fill level is particularly low.
- Constructions in which the built-in element is fastened to a frame or a cover section typically have the problem that the built-in element cannot reach right up to the bottom section. Rather it is over A certain distance between the wall at the bottom section and the lower tip of the built-in element is usually necessary for various reasons. This distance is necessary in some constructions, for example, in order to enamel both the top of the built-in element and the underlying wall.
- an installation element is attached to the cover section via a passage and a flange - such an installation element can, for example, be enamelled separately, a certain safety distance from the sensitive enamel layer of the base section is required at the lower end.
- a built-in element is often not guided very far down into the container. The invention thus allows a disruptive effect without special measures and in contrast to many constructions of the prior art, even when the filling level of the container is particularly low, without special measures.
- the built-in element can be elongate and/or have a longitudinal axis which is oriented at least substantially vertically.
- the built-in element can, for example, extend at least essentially vertically upwards, starting from the material connection, which leads to a particularly advantageous arrangement with regard to the power transmission of a flow in the container.
- the built-in element can preferably extend at least essentially vertically upwards, starting from a region of the base section that is directed upwards with its surface.
- the integral connection is then in this very area.
- the area of the bottom section with the surface facing upwards is close to a stirring device that is typically present.
- the connection is therefore in the area particularly influenced by the flow. This is beneficial in terms of leverage. Because the strongest flow has the lowest leverage due to the advantageous arrangement.
- connection is preferably at a distance from a cylindrical section of the wall, in particular in the horizontal direction with a distance of at least 1%, particularly preferably at least 2% of an inner diameter of the container and/or the cylindrical section.
- the built-in element is fastened to the wall by means of only one connection and/or that the connection has only one connection area.
- the built-in element can, for example, be attached exclusively to the floor section and/or the integral connection can be the only connection between the built-in element and the wall.
- connection can advantageously be arranged below a stirring device.
- connection can, for example, be at least essentially tubular and/or have and/or form an at least essentially tubular transition between the built-in element and the base section.
- connection is designed as a welded connection.
- welded connection can have a circumferential and/or ring-shaped weld seam, for example.
- the surface of the bonded connection can be processed, for example, by grinding and/or sandblasting. Then, for example, the material connection can be checked.
- the surface of the material connection can be enamelled, for example.
- the built-in element has a first section, in particular a connecting section, and in this section is at least essentially tubular, circular-cylindrical and/or with a circular cross-section is formed.
- the built-in element has a second section, wherein the built-in element has an at least essentially circular, elliptical, flattened or polygonal, in particular triangular or quadrangular, cross section in the second section.
- the built-in element has a first section and a second section, a different cross section being provided in the first section than in the second section.
- the cross section can relate, for example, to an outer surface and/or to an inner surface of the built-in element.
- the section or sections can in principle be of cylindrical design, for example.
- connection section can be provided whose shape is optimized for the production and/or stability of the connection.
- a disruption section can be provided, the shape of which is optimized for the disruption effect as a baffle.
- the built-in element has an at least essentially cylindrical, preferably circular-cylindrical, section at least in one area of the material connection, the cylindrical section, preferably with at least essentially constant cross-section, extending further downwards, starting from the material connection extends.
- the built-in element has a cavity, the container having a container temperature control system and the cavity being led to the outside in such a way that it passes through the container temperature control system.
- the built-in element can have a temperature control device, for example.
- the built-in element can have a first fluid passage and a second fluid passage as well as a fluid line between the fluid passages for a tempering fluid, in particular wherein the tempering fluid can flow through the built-in element through the fluid line. This allows an advantageous temperature control effect for the fluid present in the container.
- the first fluid passage can advantageously be connected, in particular directly, to a container temperature control system, in particular a double-walled cavity or a coiled pipe or half-pipe, or to an external connection or form such a connection.
- the second fluid passage can advantageously be connected, in particular directly, to a container temperature control system, in particular a double-walled cavity or a coiled tube or half-tube.
- the second fluid passage can also be connected to an external connection or form one.
- the connection to the container temperature control system allows for simple construction and operation.
- the connection to the external connection allows the temperature control device of the built-in element to be controlled in a particularly needs-based manner.
- the first fluid passage can preferably be designed as an inlet for the fluid line of the built-in element.
- the second fluid passage can preferably be designed as an outlet for the fluid line of the built-in element.
- the fluid line of the built-in element can preferably be designed to be self-draining and/or completely drainable. This allows easy maintenance and handling of the container.
- self-draining is meant that the Fluid line is aligned and shaped in the mounting element so that gravity drains the fluid by itself - when no pressure is applied and the passages are not blocked, such as by valves or the like.
- the temperature control device of the built-in element can be set up so that it is emptied into the container temperature control system.
- the fluid line of the built-in element and a container temperature control system can have a common outlet.
- This outlet can be arranged, for example, on a bottom section of the container and/or below the material connection.
- the container temperature control system can also be designed to be self-draining.
- the fluid line of the built-in element defines a fluid return path and a fluid return path.
- the fluid return path and/or the fluid return path can preferably extend over at least essentially the entire length of the built-in element.
- the first and second fluid passageways may both be located at the lower end of the mounting member.
- the fluid line of the built-in element is defined in a first line section, in particular a fluid route, preferably completely, by an intermediate wall, in particular a tube.
- the fluid line is defined in a second line section, in particular a fluid return path, partly by the outer wall of the built-in element and/or partly by an intermediate wall, in particular a tube.
- This allows for a simple construction, for example for connection to a external connection, such as a tempering fluid supply.
- the intermediate wall can, for example, be welded to the outer wall of the double wall.
- the intermediate wall is designed as a tube.
- the tube can be spaced from the outer wall at least in sections, preferably at least essentially over its entire length within the built-in element and/or at least essentially over its entire circumference and/or arranged concentrically to the outer wall. A large heat exchange effect can thus be achieved with a particularly simple structure.
- the built-in element includes a fluid line that forms a fluidic connection between the receiving space and an external connection.
- this further development allows a liquid to be discharged from a height in the container at which a fluid passage of the fluid line is provided on the receiving space side.
- a device for phase separation can thus be implemented in a particularly simple manner. That phase which is arranged in the fluid passage can simply flow out through the fluid line due to the attachment of the built-in element on the bottom side. It is therefore not even necessary to have a pump for the discharge of a phase.
- a measuring device is fastened and/or arranged on the bottom section, preferably a temperature measuring probe, in particular for detecting the temperature of the medium inside the container.
- FIG. 1 shows a sectional view of an embodiment of an enamelled container, for example for use in chemical processes.
- FIG. 2 shows the container of FIG. 1 in a perspective sectional representation.
- Fig. 3 shows a further sectional view of the container of Figs. 1 and 2.
- FIG. 4 corresponds to FIG. 1, but primarily emphasizes dimensions.
- FIG 5 illustrates another embodiment of an enamelled container.
- FIG 6 illustrates another embodiment of an enamelled container.
- FIG. 1 and 2 show a container 10 in a longitudinal section.
- Figures 1 and 2 are referred to together because of the similarity of the illustration, unless specifically stated otherwise.
- the container 10 comprises a lid section 12, a cylindrical section 14 and a bottom section 16.
- the sections 12, 14, 16 can be formed separately from one another, for example, and then joined, in particular welded, at the reference points 18, 20 in a cohesive manner.
- the sections 12 , 14 , 16 thus form a wall of the container 10 which defines a receiving space 22 inside the container 10 .
- the receiving space 22 serves to receive a fluid, for example for carrying out a chemical process within the container 10.
- the wall or the sections 12, 14, 16 are enameled from the inside in order to form a corrosion protection against sometimes chemically aggressive fluids in the receiving space 22.
- a stirring device 24 is arranged in the receiving space 22 . This is effective in the area of the bottom section 16 with inclined agitator blades 26 which are driven by an agitator shaft 28 .
- the agitator shaft 28 extends from the outside into the receiving space 22 and runs through a passage 30 provided in the cover section 12.
- Additional passages 32 are provided on the cover section 12 , via which various functional devices can be inserted into the receiving space 22 as built-in elements. Such an installation element can be fastened to the passage 32 in question, for example via a flange connection. No such functional devices or built-in elements are shown in the figures, but the passages 32 are shown open.
- the passageways 32 are typically closed during operation of the container 10, whether with a fitting or with a lid.
- Functional devices that can be introduced via the passages 32 can be, for example, supply lines, discharge lines and/or measuring devices. Other devices for influencing the chemical process are also possible - in principle also baffles.
- the container 10 At the bottom section 16, more precisely at the lowest point of the container 10, the latter has an outlet 34.
- the container 10 is designed to be self-draining, ie a liquid present in it runs off automatically, at least essentially completely, after the outlet 34 has been opened due to the force of gravity.
- the container 10 has a container temperature control system 36 which is designed as a double-wall system.
- the container temperature control system 36 includes an outer wall 38 and an inner wall, which is essentially formed by the wall of the cylindrical section 14 and the wall of the bottom section 16 . Between the outer wall 38 and the inner wall 14, 16, a cavity 40 is defined, through which a tempering fluid for the purpose of tempering an im Recording space 22 existing liquid can be passed.
- lateral connections 42 are also provided, which serve as inlets for the tempering fluid into cavity 40 .
- the container temperature control system 36 also includes a connection 44 which serves as an outlet for the temperature control fluid. Temperature control can include cooling and/or heating, for example.
- a built-in element 46 designed as a baffle is arranged in the receiving space 22 and is also enameled on an outer surface facing the fluid present in the receiving space.
- the built-in element 46 is fastened to the base section 16 by means of a material connection 48 .
- the material connection 48 is designed as a welded connection.
- An outer wall 50 of the built-in element 46 is circular-cylindrical in a connecting section 52 .
- a necking 54 is provided on the base section 16, which extends upwards from the base section 16 and also forms a circular connection point.
- the circular shapes of the outer wall 50 and the neck 52 in the connection area correspond to one another and are butt welded.
- connection 48 can be ground and/or sandblasted after welding, for example. After the welded connection has been checked, the connection 48 can be enameled, for example, in the same process as the inner wall 12, 14, 16 of the container 10 and the outer wall 50 of the built-in element 46.
- the built-in element 46 forms a baffle.
- the outer wall 50 is formed differently in an interference section 56 than in the connecting section 52, namely also cylindrical, but laterally flattened. This is visible in FIGS. 2 and 3, for example.
- the built-in element 46 includes a temperature control system, which includes a fluid line for a temperature control fluid.
- the fluid line comprises a first line section 58, which in this embodiment is defined over its entire circumference by an intermediate wall, namely a tube 60.
- a second Conduit section 62 is defined by tube 60 on the inside and outer wall 50 on the outside.
- the tube 60 extends outwardly through the outer wall 38 of the double wall and is welded thereto for a sealed attachment.
- a connection 64 preferably serves as an inlet for the tempering fluid.
- the line section 58 thus forms a fluid return path and the line section 62 forms a fluid return path.
- the second line section 62 opens into the cavity 40 of the container temperature control system 36.
- the connection 44 thus forms a common outlet for the container temperature control system 36 and the temperature control system of the built-in element 46.
- the built-in element 66 is arranged in the receiving space 22 , enamelled on its outer surface and fastened to the bottom section 16 of the wall by means of a bonded connection 48 .
- the integral connection 48 of the built-in element 66 also has a collar 54 and is designed as a welded connection between two circular cross-sections.
- a circular-cylindrical section 68 is passed downwards through the container temperature control system 36 or through the double wall 16/38. This results in a cavity 70 of the built-in element 66 being open at the bottom.
- the built-in element 66 or its cavity 70 can be provided with a temperature control system, for example, or can remain free.
- the built-in element 66 is circular-cylindrical in a connecting section 52 with its outer wall 50 .
- the outer wall 50 of the built-in element 66 is essentially triangular, as can be seen particularly well in FIG. 1 and 2 in particular that the connections 48 of the built-in elements 46 and 66 to the bottom section 16 are arranged in a region in the receiving space 22 in which a relatively strong flow due to the activity of the stirring device 26 is to be expected. In this area, however, there is hardly any mechanical lever acting on the connection 48, so that the flow in this area can easily be withstood by the connection 48.
- a temperature measuring device 72 which is also arranged on the bottom section 16 .
- FIG. 4 corresponds to FIG. 1 , but for the sake of clarity hides a large part of the reference numbers and instead shows certain relevant size designations. Insofar as size ratios are specified here as advantageous, it is understood that these are not limited to the construction according to FIG. 4, but are generally valid.
- At least one off-center opening with a diameter f is introduced into the bottom section 16 of the enamelled container 10 during its manufacture. This opening is rounded towards the inside of the container with radius rf, in particular by creating a necking.
- a built-in element 46, 66 in particular a baffle, is materially attached, in particular welded, to the necking 54 that is produced in this way and is aligned in the direction of the interior of the container. This creates a one-piece component.
- the built-in element 46, 46 is a hollow body with a cross section and a length I. The cross section depends on the requirements of the stirring process and can be triangular, oval or even circular, for example.
- the length l of the built-in element 46, 66 is also designed according to the requirements of the stirring process. For reasons of stability, the built-in element 46, 66 should be as short as possible.
- a proven length I results in particular from the height h of the surface of the liquid at a nominal filling level H in the unstirred container.
- the enamelling process follows.
- the entire media-touched (inner) surface of the container 10 is provided with an enamel coating.
- an enamelled container for stirring essentially liquid media can be produced in a simple manner, which has at least one integrated baffle which is permanently attached to the bottom of the container.
- the upper floor or lid section 12 of the container 10 remains free of the built-in elements 46, 66, so that all of the sockets present thereon are available for carrying out the chemical process in the container (stirring process).
- the built-in elements are materially connected to the bottom section 16 and the connection point is also generously rounded with the radius rf, the result is an easy-to-clean inner surface. Furthermore, the internal volume of the container 10 is completely self-draining.
- connection between the built-in element 46, 66 and the container bottom 16 is integral and seal-free. This means there is no risk of unwanted leaks and leaks.
- the built-in elements reach down to the bottom of the tank, so that the resulting disruptive effect is always guaranteed, even with the smallest filling levels.
- the built-in elements 46, 66 can be shorter and larger in diameter and thus mechanically much more stable and less sensitive to vibrational excitation.
- the built-in element 46 can be suitably provided with a tube 60 on the inside such that the heating or cooling medium (also temperature control fluid or “service medium”) flows through it in the jacket space.
- the heating or cooling medium also temperature control fluid or “service medium”
- the surface area of the mounting element 46 helps to maximize the heat exchange in the container 10.
- the construction also allows an advantageously simple manufacture with high quality.
- Fig. 4 also shows the sectional plane of Fig. 3 with the section line G.
- Fig. 4 thus shows an advantageous stirred tank 10, comprising an upper base (or cover section), a skirt (or a cylindrical section) and a lower base (or base section) and a jacket (or a double-bottom tank temperature control system) in the cylindrical area and in the bottom area, with at least one built-in element 46 on the lower bottom of the container 10 being materially connected thereto and extending into the inner volume of the container 10 .
- the mounting element 46 is hollow on the inside and is connected to the inner volume of the cavity 40 formed by the outer wall 38 of the container 10 and the inner wall of the casing.
- the mounting element 46 has in its internal volume a tube 60 which terminates at the distance a from the upper end of the mounting element.
- the distance a is preferably between 0.5 and 1.5 times the width b of the built-in element, particularly preferably 1 b.
- the pipe 60 is preferably traversed by the connecting piece 64 arranged at the bottom in the direction of the upper end of the pipe 60 .
- the tempering fluid flows through the cavity of the built-in element 46, which surrounds the tube 60, from top to bottom. This results in an additional heat exchange surface Az.
- a cross-sectional area As formed by the inner surface of the mounting member 46 and the outer surface of the tube 60 in the mounting member 46 may preferably be made much smaller than a cross-sectional area Ar formed by the inner cross-section of the tube 60.
- a connection area between the built-in element 66 and the base section 16 can, for example, be essentially cylindrical with a diameter f and have a radius rf between the base section 16 and the built-in element 46 .
- an interior space of the built-in element 66 has no fluidic connection with the cavity 40 created by the container wall and the casing.
- FIG. A port 76 is provided which forms an inlet for the half-coil 74 .
- the built-in element 46 or its Line sections 58 and 62 are connected to the half-pipe coil 74 in such a way that the temperature control fluid coming from the inlet first makes a number of turns in the half-pipe coil 74, is then guided in the line section 58 into the installation element 46, and then via the line section 62 into the half-pipe coil 74 is - this in Fig. 5 to the right of the pipe 60 - and finally after two further turns in the half pipe coil 74 via the connection 78 is discharged.
- the container 10 again has a container temperature control system 36 designed as a double wall, which is designed largely according to FIG.
- An installation element 80 is arranged in the receiving space 22 and is fastened to the bottom section 16 via a materially bonded connection 48 .
- the built-in element 80 includes a fluid line 82 which forms a fluidic connection between the receiving space 22 and an external connection 84 .
- the fluid line 82 has a fluid passage 86 at its end facing the receiving space 22 .
- a liquid phase present at the level of the fluid passage 86 which is above a heavier liquid phase further down, can be drained.
- the heavier liquid phase can be drained off via the outlet 34, for example.
- a phase separation can be implemented.
- the interior of the fluid line 82 is preferably also enamelled.
- several such built-in elements 80 with different heights can be provided in order to separate more than two phases from one another, for example.
