- the object of the present invention is to develop a housing that quickly and is efficient to assemble and flexible to different dimensions of Insulating internals, but especially to the conditions of construction sites, to adapt
- the inventive method for producing an enclosure which is has side walls extending perpendicular to the base of the enclosure, is characterized by the fact that the side walls each consist of several panels are formed, each one provided with a sheet metal frame having the panels positioned and interconnected.
- the maximum height of all panels is determined by the height of the plurality of panels, that is, the majority of the panels have the same Height and the height of the remaining panels is less than this height.
- the panels of a side wall in each case the same extent in the Have direction perpendicular to the height of the enclosure. With the same dimensions the panels are facilitated the transport to the site.
- the panels of a side wall be dimensioned so that they each over the entire length or width of the Extend sidewall. Length or width are thereby through the Limits of the base area defined. Preferably, therefore, almost all panels have one page the same size.
- only the top and / or the has bottom row of panels a different height in particular the Difference between the required coldbox height and the due to the grid compensate for possible height and to form the roof slope.
- the panels preferably have one in the direction of the height of the enclosure Extension of 2 to 4 meters, more preferably 3 meters.
- transport problems for example by exceeding the usual transport widths avoided.

Ferner bezieht sich die Erfindung auf ein Verfahren zur Herstellung einer Einhausung, welche sich senkrecht zur Grundfläche der Einhausung erstreckende Seitenwände aufweist.The invention relates to an enclosure for parts of a Cryogenic air separation plant, which perpendicular to the base of the Housing extending side walls, wherein the extent of the Enclosure perpendicular to the base defined their height, and where the Side walls each with a consisting of several panels metal jacket are disguised. Furthermore, the invention relates to a process for the preparation an enclosure, which is perpendicular to the base of the enclosure having extending side walls.
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 cryogenic air separation by rectification to be decomposed Pre-cooled air before and at least partially liquefied. The air becomes then in one or more columns at temperatures of about 100 K. Decomposed 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.For thermal insulation, the cold parts, e.g. Columns, apparatus, Pipelines or valves, provided with an enclosure. The enclosure with the to insulating parts is also referred to as coldbox. Under a housing will in the following understood in particular a casing or a wrapper, the is suitable, one or more components of a cryogenic air separation plant absorb and thermally isolate them from the environment. The enclosure is either itself thermally isolated or can be used with appropriate thermal Insulation material to be filled.
Derartige meist quaderförmige Einhausungen weisen bisher eine Stahlkonstruktion auf, deren Dach und deren Seitenwände mit Blech verkleidet sind. Das Dokument US-B1-6 360 545 offenbart eine Tieftemperaturluftzerlegungsanlage deren Einhausung einen sich über das gesamte Volumen der Einhausung erstreckenden Rahmen aufweist, der zur Abdichtung gegen austretende Flüssigkeit mit mehreren überlappenden Blechen verlkleidet ist.Such mostly cuboid housings have so far a steel construction, whose roof and its side walls are covered with sheet metal. The document US-B1-6 360 545 discloses a cryogenic air separation plant whose enclosure has a frame extending over the entire volume of the enclosure, which is lined for sealing against leaking liquid with several overlapping sheets.
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 Eigengewicht des Blechmantels, der Einbauten und der Rohrleitungen sowie der Perlite-Isolierung und der Spülgasdruck zu berücksichtigen. For isolation, the coldbox is usually filled with perlite. In the construction of the Coldbox are the external agents, such as wind and earthquakes, as well internal effects, such as the weight of the sheet metal jacket, the internals and the Pipelines and the Perlite insulation and the purge gas pressure to be considered.
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 istThe object of the present invention is to develop a housing that quickly and is efficient to assemble and flexible to different dimensions of Insulating internals, but especially to the conditions of construction sites, to adapt
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 by a cold box of the type mentioned solved, in the direction of the height of the enclosure, the joints of the panels a side wall substantially all have the same distance from each other.
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 inventive method for producing an enclosure, which is has side walls extending perpendicular to the base of the enclosure, is characterized by the fact that the side walls each consist of several panels are formed, each one provided with a sheet metal frame having the panels positioned and interconnected.
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, the side walls of the enclosure subdivided into several individual elements. According to the invention, this division takes place in this way that the side walls in the direction of the height of the enclosure, that is in the Vertical, consisting of several elements, hereinafter referred to as panels, consist.
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, the transport of the Coldbox much easier, since all but the individual panels have the same height. Only in the planned cold box at the bottom or top Panel or individual, for example, provided with special feedthroughs Panels have a different extension towards the height of the future Cold box. Preferably, the maximum height of all panels is determined by the height of the plurality of panels, that is, the majority of the panels have the same Height and the height of the remaining 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 in each case the same extent in the Have direction perpendicular to the height of the enclosure. With the same dimensions the panels are facilitated the transport to the site. In an enclosure With a rectangular base, it has proven itself, the panels of a side wall be dimensioned so that they each over the entire length or width of the Extend sidewall. Length or width are thereby through the Limits of the base area defined. Preferably, therefore, almost all panels have one page the same size. As a rule, only the top and / or the has bottom row of panels a different height, in particular the Difference between the required coldbox height and the due to the grid compensate for possible height and to form the roof slope.
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 one in the direction of the height of the enclosure Extension of 2 to 4 meters, more preferably 3 meters. Through this preferred dimensioning of the panels are transport problems, for example by exceeding the usual transport widths avoided. Such are, for example Widths up to 3 meters possible with standard truck transports, at widths up to 3.5 meters is only a truck transport accompanying vehicle necessary.
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 in many regulations permissible height of staircases. To be attached to the enclosure Inspection facilities can thus already before the final assembly of the enclosure be connected with the appropriate panels, reducing the degree of prefabrication is further increased.
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 of four-sided circumferential U-profiles on, which is provided with a cladding sheet.
Der Rahmen der Paneele wird so dimensioniert, dass die Eigenlast der Coldbox sowie die am Aufstellungsort auftretenden Kräfte, die beispielsweise durch Wind oder 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 istThe frame of the panels is dimensioned so that the dead weight of the coldbox as well the forces occurring at the site, for example, by wind or Earthquakes can be recorded. Preferably takes place the design of the frame so that the legs of the U-profile respectively inward show, that is, the frame through the base and the legs of the U-profiles is limited to the outside. Thus, the panel has three smooth outer sides, which a connection of the panel with adjacent panels by a screwed Assembly bump is possible
Zur Verbesserung der Tragfähigkeit des Verkleidungsbleches werden senkrechte Aussteifungen vorgesehen, beispielsweise in Form von L-förmigen Stahlprofilen. To improve the carrying capacity of the panel sheet are vertical Stiffeners provided, for example in the form of L-shaped steel profiles.
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.To accommodate horizontal forces are preferably diagonal struts on attached to the frame. These can be made of round tube, H or U-profile. Has proven this particular round tube, as this is a particularly favorable Ratio of area and thus weight to the buckling stiffness. It is thus one optimal profile for the removal of compressive forces. In addition, round profiles are in various cross sections easily obtainable worldwide, so that already prefabricated frames to the load influences still prevailing at the site can be subsequently adjusted.
Die Rundrohrdiagonale kann bei gleicher Außenabmessung, d.h. gleichem 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.The round tube diagonal can be used with the same outside dimension, i. the same Diameter, adjusted by the wall thickness to the required cross section become. The coordination with the 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 stiffener also without diagonal, done over the cladding sheet.
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 übemehmen jeweils höhere 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.Preferably, the frames extend over the entire length or width of one Side surface of the enclosure. The dead weight of the enclosure and the vertical forces from the external influences are then of advantage only in the corners of the Housing located vertical U-profiles of the frame. center supports are avoided as much as possible. If the cross section of the vertical U-profiles is not sufficient to absorb the forces, the corner supports are welded by Profiles further strengthened. With few supports, the dead weight of the enclosure concentrated removed, the individual supports assume higher Compressive forces. The outward-acting influences, such as wind or earthquake, resulting tensile forces are better compensated by that Anchoring can be made 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. Advantageously, a 3 to 5 mm thick sheet steel is used as a sheet metal lining. at Determining the sheet thickness is a compromise between the static Load capacity of the sheet to find its workability and its weight. A Sheet thickness of 4mm has proven to be particularly favorable in this regard.
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.The individual panels are preferably screwed together. To one gas-tight enclosure, it is then additionally required, the Seal contact points of the panels. For this purpose, a weld is preferred used. This can be done with a small seam cross-section, as the static forces are absorbed by the screw connection and the Weld is applied only 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 übliche 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.The enclosure of the invention has over the prior art numerous advantages. The enclosure is to the most diverse plant technical boundary conditions, for example different column heights or variable dimensions of the heat exchanger blocks, customizable. In principle are also cylindrical Bopxen produced according to the invention. The engineering Editing can be done by the consequent separation of space-closing and statically required elements, or by the possibility of the raumabschließenden To reinforce elements easily, done in parallel. The usual Processing sequences (first basic engineering, then the static Calculation, then workshop drawings and at the end the material purchase and the Work preparation) must not be complied with. Far-reaching overlaps are possible, for example, the workshop drawings parallel to the static Calculation to be processed. This results in savings in the 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 required cross sections and dimensions for the room closure, In particular, the U-profiles of the panels can largely independent of the concrete project. The site-dependent components can via the parameter wall thickness of the sheet metal jacket or by additional Reinforcement profiles are taken into account. By doing that much of the cross sections can be predetermined, the panel manufacturing operation can be its Purchase material 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. The panels can already be prefabricated and due to their dimensions easily transported to the site of the enclosure. The enclosure also has a construction based on globally available components and thus can be local with no major intervention in the design worldwide available profiles are manufactured.
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.By the invention, the production of the housing is optimized because a variety of is to produce identical panels. Both in the design, the static Calculation, the preparation of the design drawings as well as in the production The enclosure can have repeat effects both within a project as well used across projects. 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 vorhandenen 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.The dimensions and thus the weight of pre-assembled segments can be in Dependence of existing crane capacities on site and existing ones Mounting options, i. be set at a very late date. A Early coordination (in the basic phase) is no longer necessary. To achieve The gas tightness necessary welds can be made at any time be made up because the bearing connection through the glands of the Panel is done. The operating times of the cranes can be reduced.
