Description

Rectifying column transportation structure

Technical Field

The utility model belongs to the field of air separation, and relates to a rectifying tower transportation structure which can be used in the transportation process of related components of a rectifying tower.

Background

With the continuous progress of rectification technology in air separation plants, more and more large rectification columns are required for the air separation plants. The biggest obstacle to large rectifying columns is the transportation size limitation, which is determined by the self weight, the inner diameter and the conventional conditions of transportation of the rectifying column. Therefore, during transportation, large rectifying towers of this type are often divided into several tower sections to reduce the transportation size of the rectifying tower. Upon arrival at the site, the tower sections will be connected and assembled at the site.

The interior of the tower section is typically provided with aluminum packing or the like. In transportation, especially long, it is necessary to keep the inside of the tower section dry, thereby preventing such packing from undergoing chemical reactions when exposed to moisture, which may cause safety hazards. For example, nitrogen may be charged in the column section, maintaining a slight positive pressure, to ensure internal drying. Thus, during transportation, it is essentially necessary to seal the opening of the tower section, and thus it is necessary to use a rectifying tower transportation structure dedicated to the rectifying tower transportation process. After arriving at the site, the rectifying tower transport structure is subjected to a series of treatments such as disassembly, assembly and the like, and finally the rectifying tower is built on the site.

Therefore, it is necessary to design a rectifying tower transportation structure, which can make the on-site assembly process convenient and efficient and ensure the reliability of the assembled rectifying tower.

Disclosure of Invention

The utility model aims to provide a rectifying tower transportation structure which can enable on-site assembly operation to be simple, convenient and rapid.

Another object of the present utility model is to provide a rectifying column transport structure that can ensure reliability of the assembled rectifying column.

The utility model provides a rectifying tower transportation structure, which comprises a tower body component. The tower body component comprises a backing plate, a tower section and a seal head. The backing plate is provided with a tower section connecting cylinder section, a head connecting cylinder section and an intermediate cylinder section positioned between the tower section connecting cylinder section and the head connecting cylinder section. The tower section forms a section of the tower body of the rectifying tower, and the tower section connecting barrel section is inserted into the tower section. The seal head is sleeved outside the seal head connecting cylinder section, so that the seal head backing plate is arranged at an opening at one side of the seal head connecting cylinder section. The tower assembly adopts a first configuration or a second configuration. In the first configuration, the inner wall surface of the tower section and the pad are connected by continuous fillet welding between the end surfaces of the tower section on the side of the connecting tube section, and the end surfaces of the head and the outer peripheral surface of the intermediate tube section are connected by continuous fillet welding. In the second configuration, the inner wall surface of the head and the pad are connected by continuous fillet welding between the end surfaces of the head connecting tube section side, and the end surface of the tower section facing the head and the outer peripheral surface of the intermediate tube section are connected by continuous fillet welding.

In one embodiment, in the first configuration, the outer circumferential surface of the intermediate barrel section and the end surface of the tower section facing the head are connected by fillet welding. In the second construction, the outer peripheral surface of the intermediate tube section and the end surface of the head are connected by fillet welding.

In one embodiment, in the first configuration, the fillet weld between the intermediate barrel section and the tower section is a break weld. In the second construction, the fillet weld between the intermediate barrel section and the closure head is a break weld.

In a first embodiment, the head connecting cylinder section is provided with a guide section tapering towards the end face of the shim plate on the side of the head connecting cylinder section. In a second configuration, the tower section connecting cylinder section is provided with a guide section tapering towards the end face of the backing plate on the side of the tower section connecting cylinder section.

In one embodiment, the backing plate is the same material as the tower section and/or the head is a different material than the tower section.

In one embodiment, the thickness of the wall of the pad is not less than the thickness of the wall of the tower section.

In one embodiment, in the first configuration, the end face of the tower section facing the head is provided in the form of a chamfer such that the end face of the tower section gradually moves away from the head radially outwardly of the tower section.

In one embodiment, the rectifying column transport structure comprises two column assemblies. The two tower body components are respectively a first tower body component adopting a first structure and a second tower body component adopting a second structure. The tower sections of the first tower body component and the second tower body component respectively form two continuous sections of the tower body of the rectifying tower, and the backing plate of the first tower body component forms a welding backing plate for butt welding the tower sections of the first tower body component and the second tower body component.

In one embodiment, the tower sections of the first tower component and the second tower component form an upper section and a lower section of the tower respectively.

In one embodiment, the first tower assembly and the second tower assembly are identically constructed. The first tower body component and the second tower body component are identical in end socket structure.

In the rectifying tower transportation structure, in the tower body assembly, the column space enclosed by the tower sections can be sealed by continuous fillet welding between the backing plates and the tower sections and between the backing plates and the end sockets, so that the sealing transportation requirement is met. After the tower body component with the first structure arrives at the site, the sealing head can be easily removed by grinding off the fillet weld section between the backing plate and the sealing head, and the firm connection between the backing plate and the tower section is maintained; for the tower body component adopting the second structure, the sealing head with the backing plate can be easily removed by grinding off the fillet weld section between the backing plate and the tower section, and only the tower section is reserved. Thus, for a tower assembly of the first configuration, the shim plates that remain connected to the tower sections may be subsequently used directly as welding shim plates for butt welding while butt welding the tower sections to other tower sections. For tower assemblies employing the second configuration, the welded backing plates may then be utilized to butt weld together with other tower sections. The rectifying tower transportation structure can enable on-site assembly operation to be simple, convenient and rapid, and reduces on-site procedures and workload of the rectifying tower, so that on-site assembly cost can be remarkably reduced.

In particular, two tower assemblies, respectively in the first and second configurations, may be mated with each other. These two tower components may be referred to as a first tower component and a second tower component, respectively. After the corresponding fillet welding sections are ground, the backing plate which is always connected with the tower sections in the first tower body assembly is directly used as a welding backing plate, and the tower sections of the two tower body assemblies can be easily butt welded together. The method can further simplify the assembly operation, reduce the on-site procedures and workload of the rectifying tower, and further reduce the on-site assembly cost.

Moreover, compare in the tower body subassembly head and tower section regard as the backing plate and butt welding rectifying column transportation structure together as the welding backing plate, when using above-mentioned rectifying column transportation structure, the head is demolishd through polishing off the angle welding section, therefore avoids realizing the demolishment of head through the cutting, and this can ensure that the tower section terminal surface is level and smooth, therefore ensures the subsequent welding quality of tower section, and then ensures the quality and the reliability of whole rectifying column.

The rectifying column transport structure is essentially an intermediate structure employed in the transporting process of the rectifying column, in particular, a column section of the rectifying column. After arriving at the site, the rectifying tower is built up through operations such as dismantling and assembling the rectifying tower transportation structure. The rectifying column transport structure may comprise a plurality of column assemblies. Each tower assembly may comprise a tower section.

To more clearly illustrate the advantages of the present utility model. A comparative example is provided herein. As a comparative example, in the tower body assembly, at least one end of the tower section is sealed by a gasket and a head. Wherein, the two ends of the cylindrical backing plate are respectively inserted into the tower section and the end enclosure. And then, taking the backing plate as a welding backing plate, and butt-welding the tower section and the end socket. When in field assembly, the part of the tower section, which is connected with the backing plate and the sealing head, is required to be cut off so as to be connected with another tower section.

The rectifying column transport structure 100 provided by the present utility model includes a column assembly. The tower assembly may be in either the first configuration or the second configuration. That is, the tower unit may be a tower unit 10a having a first configuration, as shown in FIG. 1, and may also be referred to herein as a first tower unit 10a; the second configuration of the tower unit 10b is also possible, as shown in FIG. 2, and may also be referred to herein as a second tower unit 10b.

The tower assembly 10a is first described below in connection with fig. 1. For ease of description, the circumferential direction C0 and the radial direction R0 of the rectifying column transport structure 100 are shown herein, as are the circumferential direction and the radial direction of the column body assemblies 10a, 10b and the column sections 2a, 2b, etc., which will be described later in detail.

It will be appreciated that fig. 1 and fig. 2 and 3, which will be described later, essentially show only a portion of each structure, the actual structure being a cylindrical or annular structure that is rotated about a vertical central axis located to the left of the corresponding figure. Also, in fig. 1 to 3, part of the structure is not completely shown in the vertical direction. For example, the closure head 3a, which will be described later, has a complete, closed spherical cap structure on the underside, and only the portion that ends up in the two-dot chain line is shown in fig. 1. The drawings are intended to be illustrative only and not necessarily to scale, and should not be taken to limit the scope of the utility model as claimed. The vertical central axis O1 of the first tower assembly 10a is exemplarily shown in fig. 1.

Referring to fig. 1, a tower assembly 10a includes a backing plate 1a, a tower section 2a, and a head 3a.

The shim plate 1a has a tower section connecting cylinder section 11a, a head connecting cylinder section 13a and an intermediate cylinder section 12a located between the tower section connecting cylinder section 11a and the head connecting cylinder section 13 a. It will be appreciated that the description of the shim plate 1a as having the tower section connecting barrel section 11a, the intermediate barrel section 12a and the head connecting barrel section 13a is for convenience of further description only, and does not require that the tower section connecting barrel section 11a, the intermediate barrel section 12a and the head connecting barrel section 13a must be separately provided, in the substantially illustrated embodiment, the shim plate 1a is of unitary construction, and the tower section connecting barrel section 11a, the intermediate barrel section 12a and the head connecting barrel section 13a are integrally connected together.

It is also to be understood that directional or azimuthal terms such as "upper," "lower," "vertical," and the like, as may be used herein, are generally used with reference to FIG. 1 and the manner of placement of FIG. 2 as will be referred to hereafter, unless specifically stated. The orientation word is merely for convenience of description and does not limit the actual arrangement manner. For example, during actual transport, the tower assembly 10a of FIG. 1 may be turned 90 to lie on its side, at which point "up" may become "left".

Fig. 3 shows a portion of the body 200 of an assembled rectifying column. As shown in fig. 3, the column section 2a forms a section of the column body 200 of the rectifying column.

With continued reference to fig. 1, a tower section connecting barrel section 11a is inserted into the tower section 2a. The head 3a is sleeved outside the head connecting cylinder section 13a, so that the cover gasket 1a is opened at one side of the head connecting cylinder section 13a (in fig. 1, the lower side is opened).

As previously described, the first tower assembly 10a adopts a first configuration. Referring to fig. 1, in the first configuration, the inner wall surface 21a of the tower section 2a and the backing plate 1a are connected by continuous fillet welding (fillet welded section 61a is shown in fig. 1) between the end surfaces 14a (upper end surfaces in fig. 1) of the tower section connecting cylinder section 11a side. The end face 31a of the head 3 and the outer peripheral surface 122a of the intermediate tube segment 12a are connected by continuous fillet welding (fillet welded segment 62a is shown in fig. 1). It is to be understood that by "continuous fillet" it is meant that the fillet or fillet section 61a is continuous, uninterrupted along the entire circumferential direction C0 of the tower section 2a or the tubular gasket 1a and the fillet section 62a is continuous along the entire circumferential direction C0 of the gasket 1a or the head 3a.

The closure head 3a, i.e. the closure cap, is used to close the opening of the tubular support plate 1a on the side of the closure head connecting cylinder section 13a (or on the side facing away from the tower section connecting cylinder section 11a or the tower section 2 a). For example, as shown in fig. 1, the head 3a may include a vertical barrel section 35a on the upper side and a spherical cap section 36a on the lower side. The vertical section 35a can be sleeved on the seal head connecting section 13a, and the spherical crown section 36a can close the opening.

As previously described, the tower assembly may also be the tower assembly 10b shown in fig. 2. The tower assembly 10b also includes a liner plate 1b, a tower section 2b, and a head 3b. It will be appreciated that in describing the tower assembly 10b, like elements are identified using like reference numerals (same numerals, suffix a to b) as elements of the tower assembly 10a, and that some like descriptions will sometimes be omitted for brevity.

The shim plate 1b has a tower section connecting cylinder section 11b, a head connecting cylinder section 13b and an intermediate cylinder section 12b located between the tower section connecting cylinder section 11b and the head connecting cylinder section 13 b.

The column section 2b also forms a section of the column body 200 of the rectification column, as shown in fig. 3.

With continued reference to fig. 2, a tower section connecting barrel section 11b is inserted into the tower section 2b. The head 3b is sleeved outside the head connecting cylinder section 13b, so that the cover gasket 1b is opened at one side of the head connecting cylinder section 13b (in fig. 2, the upper side is opened).

The tower assembly 10b adopts a second configuration. In the second configuration, the inner wall surface 31b of the head 3b and the gasket 1b are connected by continuous fillet welding (fillet welding section 61b is shown in fig. 2) between the end surfaces 14b (upper end surfaces in fig. 2) on the head-connecting-tube section 13b side. The end face 24b (upper end face in fig. 2) of the tower segment 2b facing the head 3b and the outer peripheral face 122b of the intermediate tube segment 12b are connected by continuous fillet welding (fillet welded segment 62b is shown in fig. 2). Similar to the foregoing, here, "continuous fillet welding" means that the fillet weld section 61b is continuous along the entire circumferential direction C0 of the gasket 1b or the head 3b, and the fillet weld section 62b is continuous along the entire circumferential direction C0 of the gasket 1b or the tower section 2b.

In general, the tower assemblies 10a, 10b each include a blanket, tower section, head, etc. configuration, with the primary difference being the change in fillet weld location, particularly the change in the object to which the inner and outer fillet weld sections are connected.

The tower components 10a, 10b used during transportation, and in particular the interior of the tower sections 2a, 2b, often need to remain sealed. This is because the tower sections 2a, 2b are typically internally provided with aluminium packing. In the transportation process, especially in the long-time transportation process, the inside of the tower sections 2a and 2b needs to be kept dry, so that the aluminum filler is prevented from undergoing chemical reaction when meeting humidity, and potential safety hazards are caused. For example, the interior of the tower body assemblies 10a, 10b (including the cylindrical space enclosed by the tower sections 2a, 2 b) may be filled with nitrogen gas, maintaining a slight positive pressure, to ensure internal drying.

In the tower assembly 10a, which is an example of one form of the tower assembly, complete sealing of the tower section 2a (in particular, the underside thereof in fig. 1) can be achieved by the continuous fillet weld sections 61a, 62a, thereby meeting sealing transportation requirements. In the tower unit 10b, which is an example of another form of the tower unit, complete sealing of the tower section 2b (in particular, the upper side thereof in fig. 2) can be achieved by means of the continuous fillet-welded sections 61b, 62b, so that the sealing transport requirements are fulfilled.

After arriving at the site, the head 3a can be easily removed by grinding away the fillet weld 62a for the tower body assembly 10a of the first configuration. Thus, as shown in fig. 3, the backing plate 1a may be used as a welding backing plate, and the tower section 2a may be butt welded to another tower section (the tower section 2b in fig. 3) to form a butt welded section 66, thereby firmly assembling the two successive sections of the tower body together. The polishing operation is very convenient. The structure of the welding backing plate is just suitable for the connection of the field tower sections, and the working procedures and the workload of the field connection and assembly of the rectifying tower can be reduced, so that the field assembly cost can be obviously reduced.

For the tower assembly 10b in the second configuration, the end closure 3b and the backing plate 1b can be easily removed by polishing away the fillet weld 62 b. Thus, as shown in FIG. 3, the tower section 2b may be butt welded to another tower section (tower section 2a in FIG. 3) using a weld backing plate to form a butt welded section 66, thereby securely assembling the two successive sections of the tower body together. Unnecessary structures such as the temporary sealing head 3b during assembly can be removed by polishing the corner welding section 62b, and the on-site assembly operation is simple, convenient and quick.

Compared to the aforementioned comparative examples, the construction of the rectifying tower transporting structure 100, particularly the tower components 10a and 10b, can make the whole field assembly process more convenient, greatly shorten the field assembly time and improve the efficiency. Moreover, in the comparative example, it is difficult to ensure that the cut surfaces of the tower sections 2a, 2b are flat at the time of on-site cutting, so that the quality of the subsequent butt welding is adversely affected. The rectifying tower transporting structure 100, particularly the tower body assemblies 10a and 10b, can easily disassemble the sealing heads and the like only by polishing the corner welding sections, and can ensure the end surfaces of the tower sections 2a and 2b to be flat without cutting, thereby ensuring the quality of butt welding and further ensuring the quality and reliability of the whole rectifying tower.

Referring to fig. 1, in the first configuration, the outer peripheral surface 122a of the intermediate cylindrical section 12a and the end surface 26a (lower end surface in the drawing) of the tower section 2a facing the head 3a may be connected by fillet welding (fillet welding section 63 a). Further, in the first configuration, the fillet weld (fillet weld section 63 a) between the intermediate barrel section 12a and the tower section 2a may be a break weld.

Referring to fig. 2, in the second configuration, the outer peripheral surface 122b of the intermediate tube section 12b and the end surface 36b of the head 3b may be joined by fillet welding (fillet welded section 63 b). Further, in the second configuration, the fillet weld (fillet weld section 63 b) between the intermediate barrel section 12b and the head 3b may be a break weld.

The intermittent welding between the intermediate tube section 12a and the tower section 2a is intermittent, i.e. along the circumferential direction C0 of the tower section 2a or the shim plate 1a. The intermittent welding between the intermediate tube section 12b and the closure head 3b is intermittent, i.e. along the circumferential direction C0 of the shim plate 1b or the closure head 3b. For example, in the corner segments 63a, 63b, each segment may be about 10mm in length, and two adjacent segments may be spaced 50mm apart. The fillet weld sections 63a, 63b may each make the overall structure of the tower assembly 10a, 10b more robust.

Referring to fig. 1, in the first configuration, the end face 26a of the tower section 2a facing the head 3a may be provided in the form of a chamfer such that the end face 26a of the tower section 2a tapers outwardly away from the head 3a in the radial direction R0 of the tower section 2a. That is, in fig. 1, the end face 26a gradually rises outward in the radial direction R0. By using the above-described structure, a bevel is formed at the end face 26a when butt welding is performed in fig. 3. Thus, the welding is convenient, and the good welding performance is ensured. For example, the bevel angle of the bevel at end face 26a may be 40-70 °. The end face 24b of the tower section 2b facing the head 3b (the upper end face of the tower section 2b in fig. 2 and 3) may be provided in a flat planar form in the radial direction R0 of the tower section 2b. The end face 24b is formed with a straight bevel, which can enhance weldability.

Referring to fig. 1, in the first configuration, the head connecting cylinder section 13a of the gasket 1a is provided with a guide section 15a tapered toward the end face (lower end face in fig. 1) of the gasket 1a on the side of the head connecting cylinder section 13 a. That is, in fig. 1, the guide section 15a tapers from top to bottom. For example, the guide section 15a may be obtained by directly forming a chamfer on the outer peripheral surface of the free end of the head connecting cylinder section 13a of the gasket 1a. Referring to fig. 2, in the second configuration, the tower section connecting cylindrical section 11b of the pallet 1b is provided with a guide section 15b tapered toward the end face (lower end face in fig. 2) of the pallet 1 on the tower section connecting cylindrical section 11b side. Thus, during assembly, both guide sections 15a, 15b can serve as guides to facilitate assembly.

Referring to fig. 1, taking a tower body assembly 10a as an example, the wall thickness t1 of the backing plate 1a is not smaller than the wall thickness of the tower section 2a. That is, the wall thickness t1 of the shim plate 1a is greater than or equal to the wall thickness of the tower section 2a. Thus, when the backing plate 1a is used as a welding backing plate, welding can be facilitated, and good welding performance can be ensured. Referring to fig. 2, the wall thickness t1 of the backing plate 1b of the tower body assembly 10b is also not less than the wall thickness of the tower section 2b.

Taking the tower body assembly 10a as an example, the materials of the backing plate 1a and the tower section 2a may be the same, for example, stainless steel. This can ensure weldability with each other. Furthermore, the backing plate 1a remains in the assembled rectifying column, and good stability can be ensured. The material of the head 3a and the tower section 2a may be different. For example, the tower section 2a is made of stainless steel, and the head 3a is made of carbon steel, so that cost can be saved. The tower sections 2a and 2b are generally the same material as the tower sections of the tower body 200. Similarly, in the tower body assembly 10b, the material of the backing plate 1b and the tower section 2b may be the same, and the material of the head 3b and the tower section 2b may be different.

As mentioned previously, fig. 3 shows a portion of the body 200 of an assembled rectifying column. Preferably, rectifying column transport structure 100 may comprise two column assemblies. The two tower units may be a first tower unit 10a in a first configuration and a second tower unit 10b in a second configuration, respectively, as shown in fig. 1 and 2, respectively.

It is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not intended to be limiting with respect to time sequence, number, or importance, but are not to be construed as indicating or implying a relative importance or implicitly indicating the number of features indicated, but merely for distinguishing one feature from another in this disclosure. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. As previously described, the first column assembly 10a and the second column assembly 10b may each independently constitute a column assembly for transporting a rectifying column. Thus, the tower assemblies 10a, 10b may be separately provided, i.e., independent of each other, and may be completely separated, as shown in fig. 1 and 2, respectively. For example, the tower assemblies 10a, 10b may be separately placed in different locations on a vehicle, or even on different vehicles during transportation.

The column sections 2a, 2b of the first column assembly 10a and the second column assembly 10b may each constitute two successive sections 20a, 20b of the column body 200 of the rectification column. The backing plate 1a of the first tower assembly 10a may constitute a weld backing plate that butt welds the tower sections 2a, 2b (i.e., the two sections 20a, 20 b) of the first and second tower assemblies 10a, 10b.

In this way, the tower section 2a of the first tower unit 10a may be docked with the tower section 2b of the second tower unit 10b, thereby completing the assembly of two adjacent sections of the tower 200. As previously described, after the tower assembly 10a is transported to the site, the fillet weld 62a may be ground away, the head 3a removed, and only the tower section 2a and the shim plate 1a left. With respect to the tower body assembly 10b, the fillet weld 62b may be ground away to remove the liner plate 1b and the head 3b, leaving only the tower section 2b. The tower sections 2a, 2b are then firmly joined together by butt welding with the shim plate 1a as a welding shim plate, as shown in fig. 3. Thus, the whole field installation process is convenient and efficient. The pad 1a is also called a permanent pad, the pad 1b is also called a temporary pad, and the seal heads 3a, 3b can be called transport seal heads or temporary seal heads.

As shown in fig. 3, the tower sections 2a, 2b of the first and second tower assemblies 10a, 10b may form an upper section 20a and a lower section 20b, respectively, of the tower body 200. That is, at the site of the rectifying column installation or during the operation of the rectifying column, the column section 2a constitutes the upper one 20a of the two subsequent column sections, while the column section 2b constitutes the lower one 20b of the two subsequent column sections. It will be understood that "upper section 20a and lower section 20b" herein constitute the aforementioned special statement regarding the direction words, upper section 20a and lower section 20b being the upper and lower sections after the rectifying column assembly is completed. At this time, the tower section 2a with the welded shim plates (shim plates 1 a) left in the tower body 200 is above the tower section 2b. That is, the fillet 61a of the tower body 200 (tower section 2 a) between the butt joint and the pad 1a is upward, which is more suitable for the flow direction of the reflux liquid in the rectifying tower from top to bottom.

It should be noted that the body 200 of the rectifying tower may be divided into two sections, or may be divided into more than two sections, including three sections, four sections, five sections, and so on. For an intermediate tower section with both ends required to be connected with the corresponding tower section and both ends opened, the upper end of the intermediate tower section may be a connection structure as shown in fig. 2, and the lower end may be a connection structure as shown in fig. 1. For example, taking the tower unit 10a as an example, the lower end structure of the tower section 2a of the tower unit 10a is shown in fig. 1, and the upper end structure may also be shown in fig. 2. The structure of the other end of the tower units 10a, 10b is not limited herein, and obviously this is not excluded.

Referring to fig. 1 and 2, the configuration of the pads 1a, 1b of the first and second tower assemblies 10a, 10b may be identical.
