Tieftemperaturluftzerlegungsanlage, welche sich senkrecht zur Grundfläche der Einhausung erstreckende Seitenwände aufweist, wobei die Ausdehnung der Einhausung senkrecht zur Grundfläche deren Höhe definiert, und wobei die Seitenwände jeweils mit einem aus mehreren Paneelen bestehenden Blechmantel verkleidet sind. Ferner bezieht sich die Erfindung auf ein Verfahren zur Herstellung einer Einhausung, welche sich senkrecht zur Grundfläche der Einhausung erstreckende Seitenwände aufweist.Low-temperature air separation plant, which has side walls extending perpendicular to the base area of the housing, the extent of the housing defining its height perpendicular to the base surface, and the side walls each being clad with a sheet metal jacket consisting of several panels. Furthermore, the invention relates to a method for producing an enclosure which has side walls extending perpendicular to the base area of the enclosure.
Bei der Tieftemperaturluftzerlegung durch Rektifikation wird die zu zerlegende Einsatzluft vorher abgekühlt und mindestens zu einem Teil verflüssigt. Die Luft wird dann in einer oder mehreren Kolonnen bei Temperaturen von etwa 100 K durch Rektifikation zerlegt.In the case of low-temperature air separation by rectification, the feed air to be separated is cooled beforehand and at least some of it is liquefied. The air is then separated in one or more columns at temperatures of about 100 K by rectification.
Zur thermischen Isolierung werden die kalten Teile, wie z.B. Kolonnen, Apparate, Rohrleitungen oder Ventile, mit einer Einhausung versehen. Die Einhausung mit den zu isolierenden Teilen wird auch als Coldbox bezeichnet. Unter einer Einhausung wird im Folgenden insbesondere eine Ummantelung oder eine Umhüllung verstanden, die geeignet ist, ein oder mehrere Bauteile einer Tieftemperaturluftzerlegungsanlage aufzunehmen und diese thermisch gegen die Umgebung zu isolieren. Die Einhausung ist entweder selbst thermisch isoliert oder kann mit geeignetem thermischen Isolationsmaterial gefüllt werden.The cold parts, e.g. Columns, apparatus, pipes or valves, provided with a housing. The housing with the parts to be insulated is also referred to as a cold box. In the following, a housing is understood to mean, in particular, a casing or a casing which is suitable for accommodating one or more components of a low-temperature air separation plant and for thermally isolating them from the surroundings. The housing is either thermally insulated itself or can be filled with suitable thermal insulation material.
Derartige meist quaderförmige Einhausungen weisen bisher eine Stahlkonstruktion auf, deren Dach und deren Seitenwände mit Blech verkleidet sind.Such mostly cuboid housings have hitherto had a steel structure, the roof and the side walls of which are clad with sheet metal.
Zur Isolation wird die Coldbox üblicherweise mit Perlite gefüllt. Bei der Konstruktion der Coldbox sind die äußeren Einwirkungen, wie Wind und eventuelle Erdbeben, sowie innere Einwirkungen, wie das Eigengewiqht des Blechmantels, der Einbauten und der Rohrleitungen sowie der Perlite-Isolierung und der Spülgasdruck zu berücksichtigen. Aufgabe der vorliegenden Erfindung ist es, eine Einhausung zu entwickeln, die schnell und effizient zu montieren ist und flexibel an unterschiedliche Abmessungen der zu isolierenden Einbauten, insbesondere aber an die Gegebenheiten der Baustellen, anzupassen ist.The cold box is usually filled with perlite for insulation. When designing the cold box, external influences, such as wind and possible earthquakes, as well as internal influences, such as the intrinsic weight of the sheet metal jacket, the internals and the pipes, as well as the perlite insulation and the purge gas pressure, must be taken into account. The object of the present invention is to develop an enclosure which can be assembled quickly and efficiently and which can be flexibly adapted to different dimensions of the internals to be insulated, but in particular to the conditions on the construction sites.
Diese Aufgabe wird erfindungsgemäß durch eine Coldbox der eingangs genannten Art gelöst, bei der in Richtung der Höhe der Einhausung die Stoßstellen der Paneelen einer Seitenwand im Wesentlichen alle denselben Abstand voneinander besitzen.This object is achieved according to the invention by a cold box of the type mentioned at the outset, in which, in the direction of the height of the housing, the joints of the panels of a side wall are essentially all at the same distance from one another.
Das erfindungsgemäße Verfahren zur Herstellung einer Einhausung, welche sich senkrecht zur Grundfläche der Einhausung erstreckende Seitenwände aufweist, zeichnet sich dadurch aus, dass die Seitenwände jeweils aus mehreren Paneelen gebildet werden, die jeweils einen mit einer Blechverkleidung versehenen Rahmen aufweisen, wobei die Paneele positioniert und miteinander verbunden werden.The method according to the invention for producing an enclosure which has side walls extending perpendicularly to the base area of the enclosure is characterized in that the side walls are each formed from a plurality of panels, each of which has a frame provided with a sheet metal cladding, the panels being positioned and with one another get connected.
Aus transporttechnischen Gründen ist es erforderlich, die Seitenwände der Einhausung in mehrere Einzelelemente zu unterteilen. Erfindungsgemäß erfolgt diese Teilung so, dass die Seitenwände in Richtung der Höhe der Einhausung, das heißt in der Vertikalen, aus mehreren Elementen, im Folgenden als Paneelen bezeichnet, bestehen.For transport reasons, it is necessary to divide the side walls of the housing into several individual elements. According to the invention, this division takes place in such a way that the side walls in the direction of the height of the housing, that is to say in the vertical direction, consist of several elements, hereinafter referred to as panels.
Durch die erfindungsgemäße Unterteilung der Seitenwände wird der Transport der Coldbox deutlich erleichtert, da bis auf einzelne Paneele alle dieselbe Höhe aufweisen. Lediglich das in der geplanten Coldbox an unterster oder oberster Stelle vorgesehene Paneel oder einzelne, beispielsweise mit speziellen Durchführungen versehene Paneele, besitzen eine andere Ausdehnung in Richtung der Höhe der zukünftigen Coldbox. Vorzugsweise wird dabei die maximale Höhe aller Paneele durch die Höhe der Mehrzahl der Paneele bestimmt, das heißt, die Mehrzahl der Paneele hat dieselbe Höhe und die Höhe der übrigen Paneele ist geringer als diese Höhe.The subdivision of the side walls according to the invention makes the transport of the cold box significantly easier since, apart from individual panels, they all have the same height. Only the panel provided at the lowest or uppermost position in the planned cold box or individual panels, for example provided with special bushings, have a different extension in the direction of the height of the future cold box. The maximum height of all panels is preferably determined by the height of the plurality of panels, that is to say the majority of the panels have the same height and the height of the other panels is less than this height.
Es ist günstig, wenn die Paneele einer Seitenwand jeweils dieselbe Ausdehnung in der Richtung senkrecht zur Höhe der Einhausung aufweisen. Bei gleicher Dimensionierung der Paneele wird der Transport zum Aufstellungsort erleichtert. Bei einer Einhausung mit einer rechteckigen Grundfläche hat es sich bewährt, die Paneele einer Seitenwand so zu dimensionieren, dass diese sich jeweils über die gesamte Länge bzw. Breite der Seitenwand erstrecken. Länge beziehungsweise Breite sind dabei durch die Begrenzungen der Grundfläche definiert. Vorzugsweise haben also fast alle Paneele einer Seite dieselbe Größe. In der Regel besitzt lediglich die oberste und/oder die unterste Reihe von Paneelen eine abweichende Höhe, um insbesondere den Unterschied zwischen der erforderlichen Coldboxhöhe und der aufgrund des Rasters möglichen Höhe auszugleichen und um die Dachneigung auszubilden.It is advantageous if the panels of a side wall each have the same extent in the direction perpendicular to the height of the housing. With the same dimensioning of the panels, the transport to the installation site is facilitated. In the case of an enclosure with a rectangular base area, it has proven useful to dimension the panels of a side wall in such a way that they each extend over the entire length or width of the Extend side wall. Length and width are defined by the boundaries of the base area. So preferably almost all panels on one side are the same size. As a rule, only the top and / or the bottom row of panels have a different height, in particular to compensate for the difference between the required cold box height and the height possible due to the grid, and to form the roof pitch.
Die Paneele besitzen in Richtung der Höhe der Einhausung vorzugsweise eine Ausdehnung von 2 bis 4 Meter, besonders bevorzugt von 3 Meter. Durch diese bevorzugte Dimensionierung der Paneele werden Transportprobleme, beispielsweise durch Überschreitung der üblichen Transportbreiten, vermieden. So sind zum Beispiel Breiten bis 3 Meter mit Standard-LKW-Transporten möglich, bei Breiten bis 3,5 Meter ist lediglich ein den LKW-Transport begleitendes Fahrzeug notwendig.The panels preferably have an extension of 2 to 4 meters, particularly preferably 3 meters, in the direction of the height of the housing. This preferred dimensioning of the panels avoids transport problems, for example by exceeding the usual transport widths. For example, widths of up to 3 meters are possible with standard truck transports, and widths of up to 3.5 meters only require a vehicle to accompany the truck transport.
Zudem entspricht ein Höhenraster von 3 Meter der in vielen Vorschriften maximal zulässigen Höhe von Treppenläufen. An der Einhausung anzubringende Begehungseinrichtungen können somit bereits vor der Endmontage der Einhausung mit den entsprechenden Paneelen verbunden werden, wodurch der Vorfertigungsgrad weiter erhöht wird.In addition, a height grid of 3 meters corresponds to the maximum permitted height of stairs in many regulations. Inspection devices to be attached to the housing can thus be connected to the corresponding panels before the final assembly of the housing, which further increases the degree of prefabrication.
Die Paneele weisen von Vorteil einen Rahmen aus vierseitig umlaufenden U-Profilen auf, der mit einem Verkleidungsblech versehen ist.The panels advantageously have a frame made of four-sided U-profiles, which is provided with a cladding panel.
Der Rahmen der Paneele wird so dimensioniert, dass die Eigenlast der Coldbox sowie die am Aufstellungsort auftretenden Kräfte, die beispielsweise durch Wind oderThe frame of the panels is dimensioned so that the dead load of the cold box as well as the forces occurring at the installation site, for example caused by wind or
Erdbeben hervorgerufen werden können, aufgenommen werden. Vorzugsweise erfolgt die Ausführung des Rahmens so, dass die Schenkel des U-Profils jeweils nach innen zeigen, das heißt, dass der Rahmen durch die Basis und die Schenkel der U-Profile nach außen begrenzt wird. Damit besitzt das Paneel drei glatte Außenseiten, wodurch eine Verbindung des Paneels mit benachbarten Paneelen durch einen geschraubten Montagestoß möglich ist.Earthquakes can be caused to be recorded. The frame is preferably designed such that the legs of the U-profile each point inwards, that is to say that the frame is delimited to the outside by the base and the legs of the U-profiles. This means that the panel has three smooth outer sides, which means that the panel can be connected to neighboring panels by means of a screwed assembly joint.
Zur Verbesserung der Tragfähigkeit des Verkleidungsbleches werden senkrechte Aussteifungen vorgesehen, beispielsweise in Form von L-förmigen Stahlprofilen. Zur Aufnahme horizontaler Kräfte werden vorzugsweise diagonale Verstrebungen an dem Rahmen angebracht. Diese können aus Rundrohr, H- oder U-Profil gefertigt sein. Bewährt hat sich hierfür insbesondere Rundrohr, da dieses ein besonders günstiges Verhältnis von Fläche und damit Gewicht zur Knicksteifigkeit aufweist. Es ist somit ein optimales Profil für die Abtragung von Druckkräften. Zudem sind Rundprofile in verschiedensten Querschnitten weltweit leicht beschaffbar, so dass auch bereits vorgefertigte Rahmen an die am Aufstellungsort herrschenden Lasteinflüsse noch nachträglich angepasst werden können.Vertical reinforcements are provided to improve the load-bearing capacity of the cladding sheet, for example in the form of L-shaped steel profiles. To absorb horizontal forces, diagonal struts are preferably attached to the frame. These can be made from round tubes, H or U profiles. Round tubing has proven particularly useful for this, since it has a particularly favorable ratio of area and thus weight to buckling stiffness. It is therefore an optimal profile for the transfer of pressure forces. In addition, round profiles in a wide variety of cross-sections can be easily procured worldwide, so that even prefabricated frames can still be adapted to the load influences prevailing at the installation site.
Die Rundrohrdiagonale kann bei gleicher Außenabmessung, d.h. gleichemThe round pipe diagonal can have the same external dimensions, i.e. the same
Durchmesser, über die Wandstärke an den erforderlichen Querschnitt angepasst werden. Die Abstimmung mit den weiteren Gewerke, z.B. mit der Verrohrung, bleibt von diesen Änderungen unberührt.Diameter with which the wall thickness can be adapted to the required cross-section. Coordination with other trades, e.g. with the piping remains unaffected by these changes.
Alternativ kann, bei entsprechend geringen horizontale Kräfte, die Aussteifung auch ohne Diagonale, dafür über das Verkleidungsblech erfolgen.Alternatively, with correspondingly low horizontal forces, the bracing can also take place via the cladding plate without a diagonal.
Vorzugsweise erstrecken sich die Rahmen über die gesamte Länge bzw. Breite einer Seitenfläche der Einhausung. Das Eigengewicht der Einhausung und die Vertikalkräfte aus den äußeren Einwirkungen werden dann von Vorteil nur von den in den Ecken der Einhausung befindlichen vertikalen U-Profilen der Rahmen übernommen. Mittelstützen werden möglichst vermieden. Falls der Querschnitt der vertikalen U-Profile nicht ausreicht um die Kräfte aufzunehmen, werden die Eckstützen durch aufgeschweißte Profile weiter verstärkt. Bei wenigen Stützen wird das Eigengewicht der Einhausung konzentrierter abgetragen, die einzelnen Stützen übernehmen jeweils höhereThe frames preferably extend over the entire length or width of a side surface of the housing. The dead weight of the housing and the vertical forces from the external influences are then advantageously only taken over by the vertical U-profiles of the frames located in the corners of the housing. Center supports are avoided as far as possible. If the cross section of the vertical U-profiles is not sufficient to absorb the forces, the corner supports are further reinforced by welded-on profiles. With a few supports, the dead weight of the housing is removed more concentrated, the individual supports take on higher ones
Druckkräfte. Die aus den äußerlich angreifenden Einwirkungen, wie zum Beispiel Wind oder Erdbeben, resultierenden Zugkräfte, werden dadurch besser kompensiert, die Verankerung kann geringer dimensioniert werden.Compressive forces. The tensile forces resulting from the external influences, such as wind or earthquakes, are better compensated for, the anchoring can be dimensioned smaller.
Von Vorteil wird als Blechverkleidung ein 3 bis 5 mm dickes Stahlblech verwendet. Bei der Festlegung der Blechdicke ist ein Kompromiss zwischen der statischen Tragfähigkeit des Blechs, dessen Verarbeitbarkeit und dessen Gewicht zu finden. Eine Blechdicke von 4mm hat sich in dieser Hinsicht als besonders günstig erwiesen. Die einzelnen Paneele werden vorzugsweise miteinander verschraubt. Um eine gasdichte Einhausung zu erreichen, ist es dann zusätzlich noch erforderlich, die Kontaktstellen der Paneele abzudichten. Hierzu wird bevorzugt eine Schweißnaht eingesetzt. Diese kann mit einem geringen Nahtquerschnitt ausgeführt werden, da die statischen Kräfte durch die Schraubverbindung aufgenommen werden und die Schweißnaht lediglich zu Dichtungszwecken angebracht wird.A 3 to 5 mm thick steel sheet is advantageously used as sheet metal cladding. When determining the sheet thickness, a compromise has to be found between the static load-bearing capacity of the sheet, its workability and its weight. A sheet thickness of 4mm has proven to be particularly favorable in this regard. The individual panels are preferably screwed together. In order to achieve a gas-tight enclosure, it is then additionally necessary to seal the contact points of the panels. For this purpose, a weld seam is preferably used. This can be carried out with a small seam cross-section, since the static forces are absorbed by the screw connection and the weld seam is only applied for sealing purposes.
Die erfindungsgemäße Einhausung weist gegenüber dem Stand der Technik zahlreiche Vorteile auf. Die Einhausung ist an die unterschiedlichsten anlagentechnischen Randbedingungen, beispielsweise unterschiedliche Säulenhöhen oder variable Abmessungen der Wärmetauscherblöcke, anpassbar. Im Prinzip sind auch zylindrische Bopxen erfindungsgemäß herstellbar. Die ingenieurtechnische Bearbeitung kann durch die konsequente Trennung von raumabschließenden und statisch erforderlichen Elementen, bzw. durch die Möglichkeit, die raumabschließenden Elemente leicht verstärken zu können, parallel erfolgen. Die üblicheThe housing according to the invention has numerous advantages over the prior art. The housing can be adapted to a wide variety of technical conditions, for example different column heights or variable dimensions of the heat exchanger blocks. In principle, cylindrical bopxes can also be produced according to the invention. The engineering work can be carried out in parallel through the consequent separation of room-enclosing and statically required elements or through the possibility of being able to easily reinforce the room-enclosing elements. The usual
Bearbeitungsfolgen (zunächst Basicengineering, anschließend die statische Berechnung, dann Werkstattzeichnungen und am Ende der Materialeinkauf und die Arbeitsvorbereitung ) muß nicht eingehalten werden. Weitreichende Überlappungen sind möglich, beispielsweise können die Werkstattzeichnungen parallel zur statischen Berechnung bearbeitet werden. Hieraus resultieren Einsparungen in der Bearbeitungsdauer und somit kürzere Lieferzeiten.Processing sequences (first basic engineering, then the static calculation, then workshop drawings and at the end of material purchasing and work preparation) do not have to be observed. Extensive overlaps are possible, for example, the workshop drawings can be processed in parallel to the static calculation. This results in savings in processing time and thus shorter delivery times.
Die für den Raumabschluss erforderlichen Querschnitte und Dimensionen, insbesondere die U-Profile der Paneele, können großenteils unabhängig von dem konkreten Projekt festgelegt werden. Die aufstellungsortabhängigen Bauteile können über den Parameter Wandstärke des Blechmantels oder durch zusätzliche Verstärkungsprofile berücksichtigt werden. Dadurch dass ein Großteil der Querschnitte vorab festgelegt werden kann, kann der die Paneele fertigende Betrieb seinen Materialeinkauf unabhängig von der statischen Berechnung der Einhausung tätigen.The cross sections and dimensions required for the room closure, in particular the U-profiles of the panels, can largely be determined independently of the specific project. The site-dependent components can be taken into account via the parameter wall thickness of the sheet metal jacket or through additional reinforcement profiles. Because a large part of the cross-sections can be determined in advance, the company manufacturing the panels can do its material purchases independently of the static calculation of the housing.
Die Paneele können bereits vorgefertigt werden und aufgrund ihrer Dimensionierung leicht an den Aufstellungsort der Einhausung transportiert werden. Die Einhausung besitzt zudem eine Konstruktion auf der Basis von weltweit verfügbaren Bauelementen und kann somit ohne große Eingriffe in die Konstruktion weltweit mit vor Ort erhältlichen Profilen gefertigt werden. Durch die Erfindung wird die Fertigung der Einhausung optimiert, da eine Vielzahl von identischen Paneelen herzustellen ist. Sowohl bei der Auslegung, der statischen Berechnung, der Erstellung der Ausführungszeichnungen als auch bei der Herstellung der Einhausung können Wiederholeffekte sowohl innerhalb eines Projektes als auch projektübergreifend genutzt werden. Der projektspezifische Aufwand für die statische Berechnung wird deutlich reduziert.The panels can be prefabricated and, due to their dimensions, easily transported to the installation site of the housing. The housing also has a construction based on components that are available worldwide and can therefore be manufactured worldwide without major intervention in the construction using locally available profiles. The manufacture of the housing is optimized by the invention, since a large number of identical panels have to be produced. Repetitive effects can be used both within a project and across projects, both in the design, the static calculation, the creation of the execution drawings and the manufacture of the housing. The project-specific effort for the static calculation is significantly reduced.
Die Abmessungen und somit das Gewicht von vormontierten Segmenten kann in Abhängigkeit der vorhandenen Krankapazitäten vor Ort und den vorhandenenThe dimensions and thus the weight of pre-assembled segments can depend on the existing crane capacities on site and the existing ones
Montagemöglichkeiten, d.h. zu einen sehr späten Zeitpunkt festgelegt werden. Eine frühzeitige Abstimmung (in der Basicphase) ist nicht mehr erforderlich. Zur Erzielung der Gasdichtheit notwendige Schweißnähte können zu einem beliebigen Zeitpunkt nachgeholt werden, da die tragende Verbindung durch die Verschraubungen der Paneele erfolgt. Die Einsatzzeiten der Kräne können reduziert werden.Installation options, i.e. to be set at a very late date. Early coordination (in the basic phase) is no longer necessary. The welds necessary to achieve gas tightness can be made up at any time, since the load-bearing connection is made by the screw connections of the panels. The operating times of the cranes can be reduced.

In Figur 1 ist ein Teilaufbau einer erfindungsgemäßen Einhausung gezeigt, die als Coldbox zur Aufnahme von Bauteilen einer Tieftemperaturluftzerlegungsanlage dient. In der Coldbox sind beispielsweise die Niederdrucksäule und/oder derFIG. 1 shows a partial construction of a housing according to the invention, which serves as a cold box for receiving components of a low-temperature air separation plant. In the cold box are for example the low pressure column and / or the
Hauptkondensator und/oder die Rohargonsäule mit entsprechenden Zubehörteilen untergebracht.Main condenser and / or the raw argon column housed with appropriate accessories.
Die gezeigte Coldbox hat eine rechteckige Grundfläche mit der Länge L und der Breite B. Als Höhe der Coldbox wird deren Ausdehnung in einer Richtung senkrecht zur Grundfläche bezeichnet. Die Seitenwände der Coldbox sind aus einer Vielzahl von Paneelen 1a, 2a, 1b, 2b aufgebaut. Die Paneelen 1a und 2a bzw. 1b und 2b sind jeweils identisch ausgeführt und erstrecken sich jeweils über die gesamte Ausdehnung L bzw. B der entsprechenden Coldbox-Seitenwand.The cold box shown has a rectangular base with the length L and the width B. The height of the cold box is its extent in a direction perpendicular to the Base area designated. The side walls of the cold box are constructed from a large number of panels 1a, 2a, 1b, 2b. The panels 1a and 2a or 1b and 2b are each identical and each extend over the entire extent L or B of the corresponding cold box side wall.
In Figur 2 ist ein Paneel detaillierter dargestellt. Das Paneel besteht aus einem rechteckigen Rahmen aus U-Profilen 3, 4 aus Stahl. Die Länge der in der Coldbox nach deren Aufstellung waagerecht verlaufenden U-Profile 4 entspricht in dem dargestellten Beispiel der Seitenlänge L der Coldbox. Die Paneele für die Seiten mit der Breite B werden entsprechend ausgeführt. Die Länge der im eingebauten Zustand senkrecht verlaufenden U-Profile 3 beträgt vorzugsweise 3 m.A panel is shown in more detail in FIG. The panel consists of a rectangular frame made of U-profiles 3, 4 made of steel. The length of the U-profiles 4 which run horizontally in the cold box after its installation corresponds to the side length L of the cold box in the example shown. The panels for the sides with the width B are designed accordingly. The length of the U-profiles 3 which run vertically in the installed state is preferably 3 m.
Die U-Profile 3, 4 werden zu einem rechteckigen Rahmen verbunden. Diagonalen 7 aus Rundrohr werden zur Abtragung der Horizontallasten eingesetzt. Der gesamte Rahmen ist schließlich mit einem Blech 8 verkleidet, welches eine Dicke zwischen 3 und 5 mm, vorzugsweise 4 mm besitzt und das mit den vertikal angeordneten Profilen 6 verstärkt wird.The U-profiles 3, 4 are connected to a rectangular frame. Diagonals 7 made of round tube are used to transfer the horizontal loads. The entire frame is finally covered with a sheet 8, which has a thickness between 3 and 5 mm, preferably 4 mm and which is reinforced with the vertically arranged profiles 6.
Am geplanten Aufstellungsort der Coldbox wird ein Fundament errichtet, auf dem die untersten Paneelen 1a, 1b montiert werden. Es werden zwei an einer Ecke aneinander angrenzende Paneelen 1a, 1b in Position gebracht und miteinander verschraubt.At the planned installation location of the cold box, a foundation is built on which the bottom panels 1a, 1b are mounted. Two panels 1a, 1b adjoining one another at a corner are brought into position and screwed together.
Unabhängig von der Montage auf dem Fundament können, vorzugsweise in Fundamentnähe, auf einen Grundrahmen weiter oben angeordnete Paneele zu Segmenten vormontiert werden.Irrespective of the installation on the foundation, panels arranged further up on a base frame, preferably near the foundation, can be pre-assembled into segments.
Die Verbindung der Paneelen 1a und 1b ist in Figur 3 im Detail dargestellt. Die Paneele 1a und 1b werden so angeordnet, dass die Basis des vertikalen U-Profils 3a des Paneels 1a und ein Schenkel des vertikalen U-Profils 3b des Paneels 1b aneinandergrenzen. An der Kontaktstelle werden die beiden U-Profile 3a und 3b über eine Schraubverbindung 9 miteinander verbunden. Die Kontaktstelle der beiden U- Profile 3a und 3b wird anschließend mit einer Schweißnaht 10 versehen, um eine gasdichte Verbindung der beiden Paneele 1a und 1b zu erreichen. Die beiden vertikalen U-Profile 3a und 3b sowie die entsprechenden vertikalen U- Profile der darüber liegenden Paneele, beispielsweise der Paneele 2a und 2b (Figur 1), bilden die Eckstützen der Coldbox. Zur Verstärkung der Coldbox-Ecken wird, wenn statisch erforderlich, zusätzlich ein L-Profil 11 angeschweißt, welches sich über die Höhe mehrerer Paneele 1a, 2a oder über die gesamte Höhe H der Coldbox erstreckt und gemäß den statischen Erfordernissen abgestuft werden kann.The connection of the panels 1a and 1b is shown in detail in FIG. The panels 1a and 1b are arranged such that the base of the vertical U-profile 3a of the panel 1a and one leg of the vertical U-profile 3b of the panel 1b adjoin one another. At the contact point, the two U-profiles 3a and 3b are connected to one another via a screw connection 9. The contact point of the two U-profiles 3a and 3b is then provided with a weld seam 10 in order to achieve a gas-tight connection of the two panels 1a and 1b. The two vertical U-profiles 3a and 3b as well as the corresponding vertical U-profiles of the overlying panels, for example panels 2a and 2b (FIG. 1), form the corner supports of the cold box. To reinforce the cold box corners, an L-profile 11 is additionally welded on, if it is statically necessary, which extends over the height of several panels 1 a, 2 a or over the entire height H of the cold box and can be graded according to the structural requirements.
Nach Fertigstellung des untersten Paneelrings 1a, 1b werden die nächsten Paneele 2a, 2b auf den untersten Paneelring 1a, 1b positioniert und mit diesem verbunden. Hierzu werden die aufeinanderliegenden waagerechten U-Profile 4 des unteren Paneels 1a und des darüber befindlichen Paneels 2a miteinander verschraubt. Zur Erzeugung einer gasdichten Coldbox wird auch die Kontaktstelle der beiden Paneelen 1a und 2a mit einer Schweißnaht versehen. Die Eckverbindung der Paneele 2a und 2b des oberen Paneelringes erfolgt in der oben anhand von Figur 3 erläuterten Art und Weise.After completion of the bottom panel ring 1a, 1b, the next panels 2a, 2b are positioned on the bottom panel ring 1a, 1b and connected to it. For this purpose, the superimposed horizontal U-profiles 4 of the lower panel 1a and the panel 2a located above are screwed together. To produce a gas-tight cold box, the contact point of the two panels 1a and 2a is also provided with a weld seam. The corner connection of the panels 2a and 2b of the upper panel ring takes place in the manner explained above with reference to FIG. 3.
Falls erforderlich, können in die Coldbox zusätzlich Träger 12 (siehe Figur 1) eingebracht und an den Paneelen befestigt werden, um an diese beispielsweise Rohrleitungen oder andere Module zu montieren. In analoger Weise kann an der Außenseite der Einhausung eine Begehungseinrichtung 13 angeordnet werden.If necessary, additional supports 12 (see FIG. 1) can be introduced into the cold box and attached to the panels in order to mount pipelines or other modules on them, for example. In an analogous manner, an inspection device 13 can be arranged on the outside of the housing.
Anstelle des beschriebenen Aufbaus der Coldbox aus einzelnen Paneelen 1a, 1b, 2a, 2b können auch vorgefertigte Segmente aus mehreren Paneelen verwendet werden.Instead of the described construction of the cold box from individual panels 1a, 1b, 2a, 2b, prefabricated segments from a plurality of panels can also be used.
In Figur 4 ist beispielsweise ein aus drei Paneelen 14, 15, 16 bestehendes vorgefertigtes Element, ein sogenanntes Feld, dargestellt. Die Paneele 14, 15, 16 werden bereits vor dem Einbau in die Coldbox miteinander verschraubt und die Verbindungsstellen mit Schweißnähten abgedichtet. Das komplette aus den drei Paneelen 14, 15 16 bestehende Feld wird dann als ein einziges Teil in die Seitenwand der Coldbox eingebaut. Die Anzahl der Paneele eines Feldes kann gemäß den Gegebenheiten auf der Baustelle, z.B. in Abhängigkeit von der vorhandenen Krankapazität, gewählt werden.FIG. 4 shows, for example, a prefabricated element consisting of three panels 14, 15, 16, a so-called field. The panels 14, 15, 16 are screwed together before installation in the cold box and the joints are sealed with welds. The complete field consisting of the three panels 14, 15 16 is then installed as a single part in the side wall of the cold box. The number of panels in a field can vary depending on the conditions at the construction site, e.g. depending on the existing crane capacity.
In Figur 5 ist ebenfalls ein aus mehreren Paneelen 17, 18, 19, 20 vorgefertigtes Segment zu sehen. Die einzelnen Paneele 17, 18, 19, 20 werden bei dieser Ausführung nicht übereinander, sondern so nebeneinander angeordnet und miteinander verbunden, dass diese einen Ring entsprechend der Größe der Coldbox bilden. Der komplette Ring wird dann an die vorgesehene Stelle der Coldbox positioniert und mit den darunter liegenden Paneelen verschraubt.FIG. 5 also shows a segment prefabricated from several panels 17, 18, 19, 20. The individual panels 17, 18, 19, 20 are in this Execution not one above the other, but arranged next to each other and connected to each other so that they form a ring according to the size of the cold box. The complete ring is then positioned at the intended location of the cold box and screwed to the panels below.
In Fig. 6 ist eine dritte Variante der Vorfertigung dargestellt. Aus mehreren Paneelen wird ein Schuss der entstehenden Einhausung vorgefertigt. Die nebeneinander liegenden Paneele bilden die Außenabmessungen L und B der Einhausung, die übereinander angeordneten Paneele bilden einen Teil der Gesamthöhe. Der Schuss kann entweder aus einzelnen Paneelen, aus vorgefertigten Feldern oder Ringen entstehen. Die Schusshöhe wird primär durch die vorhandenen Krankapazitäten bestimmt.6 shows a third variant of the prefabrication. A shot of the resulting housing is prefabricated from several panels. The adjacent panels form the outer dimensions L and B of the housing, the panels arranged one above the other form part of the overall height. The shot can either be made from individual panels, from prefabricated fields or rings. The shot height is primarily determined by the existing crane capacities.
Selbstverständlich können an die vorgefertigten Elemente ebenso wie an die einzelnen Paneele bereits vor dem Einbau in die Coldbox Anlagenteile oder Zusatzeinrichtungen, beispielsweise Rohrleitungen, Kabelschächte, Ventile oder Begehungseinrichtungen und Träger, montiert werden.Of course, system components or additional devices, such as pipes, cable ducts, valves or inspection devices and supports, can be installed on the prefabricated elements as well as on the individual panels before they are installed in the coldbox.
Neben der oben beschriebenen Vorgehensweise die Einhausung auf der Baustelle zu errichten und die Einbauten suksessive einzubauen, ist das vorgestellte Konzept auch für die sogenannte Packaged Unit Variante, d.h. die Montage der Einhausung, das Einbringen der Einbauten und der Verrohrung im Liegen und der anschließende Transport der gesamten Coldbox zum Aufstellungsort, geeignet. In addition to the procedure described above, erecting the housing on the construction site and installing the internals suksessive, the concept presented is also for the so-called packaged unit variant, i.e. the installation of the housing, the installation of the internals and the piping while lying down and the subsequent transport of the entire cold box to the installation site.
