Definitions
- the invention relates to a column system according to claim 1.
- the operating temperature of gas separation plants is generally not the same Ambient temperature.
- natural gas or air separation plants operated at low temperatures below ambient temperature.
- the cold box has a jacket that one or can be multi-layered.
- the space between the coldbox jacket and The outer wall of the column is generally covered with powdered insulating material (for Example perlite).
- EP 913653 A1 proposes that Introduce column on rails into the lying cold box. A tension the column using ropes is disclosed in DE 19737520 A1.
- the invention has for its object to provide a column system that Compensation of temperature-related dimensional changes allowed while the column was on Operating temperature is brought and that economically particularly cheap is to be produced.
- connection is preferably both radial and also axially sliding, so that when the system is cold, the temperature-related shrinkage of the column is not hindered in any direction.
- Separating columns and their containers usually have cylindrical or the like Shape up.
- the terms “column axis”, “axial”, “radial” and “Tangential” refer to the cylinder axis or a comparable one Preferred direction of the column.
- the column axis is vertical when the column is in operation.
- the “column container” can be wholly or partly through the outer wall of the Separation column be formed. It can have one or more columns (for example Double or multiple columns), as well as in addition to the column or columns envelop other apparatus parts such as capacitors or the like.
- the invention is fundamentally independent of the shape of the cold box jacket. She can be used for example with cuboid or cylindrical cold boxes. It is particularly preferably used for essentially cylindrical ones Cold boxes. Such cold boxes are used in particular when a Column container that, for example, only a single column (for example the High-pressure column or the low-pressure column of a two-column air separator), optionally with a condenser or evaporator assigned to this column, has, separately from other apparatus parts such as the main heat exchanger Cooling of the gas to be separated or further separation columns is isolated. at the invention the load is largely tangential in the column or in initiated the coat.
- the connecting links in the invention are preferably made of one or more rigid elements.
- Rigid elements essentially become “stiff" here such as profiles, strips, plates, pipes, etc., delimited from ropes or the like called flexible elements.
- the connecting links can slide in the axial direction with the column container (and rigid with the cold box jacket) or sliding in the axial direction with the cold box jacket (and rigid with the column container) or sliding in the axial direction with be connected to both.
- the connecting links can slide in the radial direction with the column container (and rigid with the coldbox jacket) or sliding in the radial direction with the Coldbox jacket (and rigid with the column container) or in the radial direction be slidably connected to both.
- the connecting links are preferably in the axial and / or radial direction sliding with the column container and in the axial or radial direction non-positively connected to the cold box jacket, which means that the column can move axially or slide radially relative to the connecting links, which in turn are not in the axial or radial direction compared to the cold box jacket move.
- the connecting links are each two at an angle to one another have arranged spokes, the column container at their intersection and face the cold box jacket at the other end.
- the spokes are formed, for example, by tubes, such as Cr-Ni round tubes. Both spokes of a connecting link are preferably in an axial plane. The angle between them is, for example, 0 ° to 160 °, preferably 90 ° to 140 °.
- the sliding connection between the column container (or cold box jacket) and connecting link can be connected to the Column container (or the cold box jacket) connected bar in Combination with a non-positive connection with the respective connecting link connected, the bar encompassing leadership are formed.
- the bar runs preferably in the axial direction and can for example be rectangular Have cross-section of a correspondingly U-shaped guide is enclosed on three sides. On the two opposite sides, the Guide preferably a small distance of 0 to 3 mm, preferably 0.5 to 1.5 mm.
- the guide or the bar be coated with a sliding coating, for example with PTFE inserts.
- the connecting links are preferably radial Direction adjustable connected to the cold box jacket.
- This measure serves to Compensation of tolerances and to avoid complex adjustment work for the Case that the cold box jacket does not have a perfect cylindrical shape.
- tubular Spokes can be made by connecting the tube axially is slotted and into the slot with the coldbox jacket non-positively connected sheet metal is introduced. After the column has been assembled, it will Connection preferably made non-positive, for example by welding. The compensation of temperature-related changes in length then takes place independently from balancing the radial manufacturing tolerances instead. (Alternatively, one corresponding adjustable connection between the links and Column containers are made, if between connecting links and cold box jacket are slidably connected.)
- the system is essentially tangential to the column container Has support, which has at least one radial link to the Coldbox coat connects.
- a transport lock of this type must be in accordance with the Setting up the column cannot be removed if, according to the invention, a sliding Connection between the column container on the one hand and the connecting member and Support exists on the other hand. This simplifies and reduces the cost of installing the Column system.
- Essentially tangential here means a direction that is no longer than 45 °, preferably not more than 30 °, most preferably not more than 15 ° of of the geometric tangential deviates.
- the support is preferably provided with one facing the column container Section of the corresponding link connected. This increases stability the transport lock.
- the invention also relates to a method for producing a column system according to claim 13 or 14.
- the method according to claim 13 is particularly suitable for standing assembly of the column system, but can can also be used for horizontal installation.
- the invention also relates to a Use of these methods according to claim 15.
- a column container 1 is arranged inside a cold box, the has a cold box jacket 2.
- the cold box jacket 2 consists in the example of a sheet metal casing 2A, which on a Scaffold is welded or reinforced by annular stiffeners (scaffold or stiffeners are indicated in Figure 1 and 2 as 2B).
- annular stiffeners are indicated in Figure 1 and 2 as 2B.
- the links 3a, 3b, 3c, 3d are arranged in and in the plane of the drawing Example offset from each other by 90 °. Your essentially identical Structure is presented in the detailed drawings.
- the column system preferably has exactly one such ring Link member located near the top of the column.
- one or more identical or similar rings can be axially offset be arranged.
- Figure 2 has the same viewing direction as Figure 1.
- Cold box jacket 2 is on the left Sheath 2A and ring stiffeners 2B shown, the outer wall of the column container on the right 1.
- Three at right angles to each other arranged Cr-Ni sheets 6, 7, 8 with stiffeners 9, 10 form a guide, the one encloses a bar formed by a rectangular aluminum lug 11.
- the bar 11 is firmly connected to the column container 1 via a reinforcing plate 12.
- the guide 6, 7, 8 can slide along the bar 11 perpendicular to the plane of the drawing.
- the remaining connecting links are essentially identical to those in the figures 2 and 3 shown.
- the cold box can concentrically enclose the column.
- an eccentric arrangement is possible, as shown in Figure 1 - quantitative exaggerated - is shown; the column axis 15 and the coldbox axis 16 are here not identical.
- Figure 6 shows a second embodiment of the invention, in which the angle ⁇ between the two legs 4, 5 of the connecting link 3 shown between Column container 1 and cold box jacket 2 much higher than in the first Embodiment is. It is about 125 ° here.
- the guide 6 'around the bar 11 is here formed in one piece and consists of a multi-edged sheet.
- the connecting links have a particularly small size.
- FIG. 7 A pair of substantially tangential supports 18, 18 'as Transport security when the column of the column system is lying down is shown in FIG. 7 shown. Otherwise, FIG. 7 does not differ from FIG. 1.
- the support 18 is connected to the connector 3 near the column end.
- guide also serves as an abutment for the support 18th
- the supports 18, 18 'can - in contrast to known transport locks - after remain in the cold box after installing the unit. On an elaborate Work step for removing the transport locks can be omitted.
