Facility and procedure for the construction of such

Abstract

The system (10) according to the invention comprises at least two transport units (11, 12) which have assemblies spanning the transport units, in particular containers spanning the transport units, which are subdivided into sub-housings (25, 26) in accordance with the subdivision predetermined by the transport units. Preferably, all interfaces of containers spanning the transport units are arranged in an intermediate space (23) between the upper side (21) of the lower transport unit (11) and the underside (22) on the upper transport unit (12). This intermediate space is preferably too narrow to allow access after the two transport units have been stacked. Flange elements (44, 54) pre-assembled on the container parts and the transport units establish the connection between the container parts (25, 26) and the transport units (11, 12) and also enable final assembly from the container interior.The invention thus enables extensive pre-assembly of the transport units and fast, safe and efficient erection of the system at the installation site.

Description

[0001] The invention relates to a system, in particular a system for air purification, in particular for air filtration, dust separation, aerosol separation or the like.

[0002] An example of an air purification system can be found in AT 167838B. This system contains several dust collection vessels, with the individual components of the system connected to each other via flanges.

[0003] Another filter system is known from DE 37 22 826 A1. This filter system has a modular design and contains several filter cartridges arranged on different levels in a frame.

[0004] DE 603 ​​10 692 T2 describes filter bags arranged parallel to each other in a large filter housing. Such filter systems can cause transport problems when transporting them in assembled form from a manufacturing site to an installation site. The filter housings may have dimensions that make them unsuitable for road transport. This is especially true if the filter system requires a multi-level housing at its installation site.

[0005] Based on this, it is the object of the invention to provide an improved system concept and an improved concept for the construction of such a system.

[0006] This object is achieved by a system having the features of claim 1 and by a method for constructing this system having the features of claim 15:

[0007] The system according to the invention can be designed, in particular, as an air purification system, although the system concept is also applicable to other systems. The system concept according to the invention is particularly suitable for systems that have boilers, filters, or other containers that, when installed, occupy more than one floor in a plant building.

[0008] The system comprises at least two transport units, each with its own housing, which can be arranged one above the other to construct a system building. The transport units are preferably cuboid-shaped and can be connected to one another at their corners. The connection is preferably made in such a way that a gap remains between the top of the lower transport unit and the bottom of the upper transport unit, but this gap is typically so narrow that it is inaccessible to fitters. For example, the clear height between the top of the lower transport unit and the bottom of the upper transport unit can be limited to a size of less than 30 cm. Nevertheless, the gap is suitable for accommodating connecting means, for example connecting means for connecting the housings of the two transport units to one another.

[0009] Container parts are arranged in the transport units, which are subcomponents of the container extending over at least two transport units. When assembled, the container parts form the container of a functional unit. Such a functional unit can be, for example, a filter housing, a cyclone separator, a pressureless container, a container subjected to negative pressure, a pressure vessel, or the like. Connecting elements are provided to connect the two container parts to one another, which can preferably be installed from an accessible interior space enclosed by the container. In this case, a connecting element, e.g., a flange element, is preferably assigned to each of the first and second container parts.This concept allows the transport units to be stacked and connected to one another, after which the pre-assembled container parts are connected by an installer located inside the container. The container to be assembled has access for this purpose. However, access to the space enclosed between the underside of the upper housing and the top of the lower housing is not necessary.

[0010] The inventive concept envisions the division of a plant building into transport units and the subdivision of containers taller than a single transport unit into container sections. This enables the pre-assembly of the plant's transport units at a workshop, the transport of the transport units by truck over public roads, and the efficient erection of the plant at the installation site with minimal assembly effort.

[0011] The housings of the transport units are preferably formed by shipping containers. The connection point between the container parts can be arranged between the housings, even if this space is not accessible from the outside. For this purpose, the shipping containers or other housings can be connected to one another using standardized connectors, such as those commonly used to connect the corner fittings of shipping containers. For assembly, the housings or shipping containers can be placed on top of one another and connected to one another, as is usual for container transport. In the simplest case, the corner fittings of the shipping containers can be positioned so that they interlock and rest on one another by gravity or secured together using bolts.If standard corner connectors for sea container fittings are used as connecting elements, they connect to both the corner fitting of the upper container and the corner fitting of the other container, clamping them together. While in the former case, only a minimal gap remains between the top of the lower container and the bottom of the upper container, the corner connectors create a slightly larger vertical gap. This gap can be large enough to allow manual access to the space. However, the gap is preferably smaller.

[0012] The connection point of the container parts is preferably designed such that, after the container part has been installed in the housing or shipping container, access to the connection between the housing and the container part is no longer required. For example, an outwardly directed flange provided on the container part can be connected to a support of the housing via a flange element. For this purpose, the flange element preferably has a section directed outward away from the container interior for connection to the housing, as well as a section directed into the container interior for later connecting the flange elements and thus the container parts to one another.

[0013] In this way, the flange element not only enables a simple assembly sequence, but also compensates for tolerances with regard to static overdetermination, which results from the fixation of the housings (sea or shipping containers) to each other and from the connection of the pre-assembled and thus firmly arranged container parts within the housings. In particular, the flange elements can exhibit a (slight) degree of flexibility for this purpose. The flange element thus has an inward-facing flange section and an outward-facing flange section and is pre-assembled on each transport unit.

[0014] Furthermore, it is possible to provide effective alignment means between the container parts. Such alignment means can, for example, be arranged on the flange elements and act between them. Alignment means can, for example, be fitting bolts arranged on the flange element of one container part and fit into fitting holes arranged in the flange element of the other container part. In this way, the alignment means can become effective, i.e., the alignment bolts penetrate into their associated fitting holes, when the transport units are placed on top of one another. These alignment means are designed to align not only the container parts, but in particular also the transport units as a whole.

[0015] Further details of advantageous embodiments of the invention emerge from the drawing as well as the associated description and subclaims.

[0016] The drawing shows: Fig. 1 a system according to the invention, in a schematic perspective view, Fig. 2 a slightly modified system according to the invention, in a schematic vertical section, Fig. 3 a construction detail on the top of a transport unit, Fig. 4 the construction detail according to Fig. 3, in side view, and Fig. 5 the connection point between the container parts and housings of the transport units, in a vertically sectioned schematic representation, Fig. 6 and Fig. 7 alternative designs of the connection point between the container parts and housings of the transport units, in a vertically sectioned schematic representation.

[0017] In Fig. Figure 1 illustrates a system 10 intended, for example, for exhaust air treatment, which may be configured as a filter system, for example. However, the system concept explained below can also be used in other systems, particularly for the treatment of gaseous material streams or the like.

[0018] The system 10 comprises at least a first transport unit 11 and a second transport unit 12, which, when the system 10 is assembled, are arranged stacked one above the other. The first transport unit 11 can, for example, be mounted on a frame 13. The frame 13 and the transport units 11, 12 form a system building. As the embodiment according to Fig. As shown in Figure 2, instead of the frame 13, a further transport unit 14 can also be provided, on which the first transport unit 11 and the second transport unit 12 are arranged, i.e., stacked. The plant building then consists of the three transport units 11, 12, and 14, which are stacked vertically one above the other. Additional transport units can be provided.

[0019] Each transport unit (11, 12 and 14) has a housing 15, 16 (and 17 in Fig. 2), which is preferably designed as a truck-transportable unit. In the preferred embodiment, the housings 15, 16, 17 are so-called shipping containers or overseas containers with dimensions standardized for container transport, for example, 40-foot containers. These housings are essentially cuboid-shaped and made of sheet steel.

[0020] According to the invention, the housings 15, 16, 17 are provided with the necessary fittings at a factory or manufacturing site, e.g., a manufacturing plant, and then transported by road to the assembly site. There, they can be loaded, for example, by crane, into the Fig. 1 and Fig. 2 and then fully assembled. Assembly is limited to making a few connections, which can be performed on-site with light tools. Each housing 15, 16, and 17 then forms one floor of the plant building of plant 10.

[0021] The finished one, for example, Fig. The exhaust air treatment system shown in Figure 1 simply needs to be connected to an operational exhaust air system via an access pipe 18 and connected to a power supply, after which the system is ready for operation. If it is used for solid matter separation, for example, dust separation, a suitable collecting device 18 can be provided below the first transport unit 11, for example in the form of a tray or the like. Other collection or conveying devices serving to collect or discharge residual matter can also be provided alternatively or additionally. Furthermore, if required, further connections can also be established between the system 10 and the environment, e.g., connections to an external water supply, wastewater, compressed air supply, data connection, or the like.

[0022] It is possible to place the transport units 10, 11 on top of each other in such a way that their corner fittings 19 interlock, as is usual with shipping containers, so that the shipping containers or housings 11, 12 are positively secured against lateral slipping. In many cases, it is sufficient if the second transport unit 12 is secured to the first transport unit 11 solely by its gravity. Alternatively, the corner fittings 10 (19a, 19b) can be connected to each other to create a fixed connection between the transport units 11, 12. Also, between the corner fittings 19a, 19b, as is Fig. 2, connectors 20 may be arranged to increase the vertical distance between the transport units 11, 12. Furthermore, the spacers 20 may be designed as locking means to firmly connect the corner fittings 19a, 19b to one another and thus firmly connect the transport units 11, 12 to one another.

[0023] A gap 23 is formed between the top side 21 of the first transport unit 11 and the bottom side 22 of the second transport unit 12, which, however, is typically inaccessible to assembly personnel due to its low height. Nevertheless, it is considered advantageous to arrange connections between components of the transport units 11, 12 precisely in this gap 23. This ensures that components extending over several transport units do not protrude significantly beyond the outer contour of the respective transport unit 11, 12 during transport. This is illustrated below using the example of Fig. 2 explains:

[0024] In the embodiment according to Fig. 2 a filter container 24 which comprises a plurality of container parts 25, 26 and optionally also 27. Each transport unit 11, 12, 14 contains precisely one container part 25, 26, 27, which is fixedly arranged in the respective housing 15, 16, 17 of the transport unit 11, 12, 14 and does not protrude, or does not protrude significantly, beyond its outer profile. The filter container 24 is thus segmented according to the transport units 11, 12, 14, i.e., according to the levels of the system 10. This applies both to systems that consist of only two transport units, for example the transport units 11, 12, and to systems that have a plurality of such transport units.

[0025] The filter container 24 can be provided with a lockable access port to allow a technician to access the container interior. For this purpose, an access opening 25a provided with a hatch, flap, lid, or door can be provided on the container part 25. Additionally or alternatively, a access port can be provided on the container part 26 or the container part 27. Furthermore, the filter container 24 can be provided with burst protection. For this purpose, the upper container part 26 can be provided with a bursting disc 26a at its upper end protruding through the ceiling of the upper housing. If necessary, the bursting disc 26a can be provided as access for a technician.

[0026] In each transport unit 11, 12, 14, not only the container parts 25, 26, 27, but also other system components can be pre-assembled, such as, for example, pipelines 28, fans 29, silencers 30, heaters, heat recovery devices, heat pumps, air treatment devices in general, discharge devices 31, compressors 32, control cabinets 33, ladders 34, 35 and man-overs 36, 37 in the ceilings and floors of each transport unit 11, 12, 14. Insofar as such system components extend over two or more floors, they are, at least preferably, divided into subcomponents within the intermediate space 23.

[0027] The container part 25 passes through the bottom 22 of the second transport unit 12. The container part 26 passes through the top 21 of the first transport unit 11. For connecting the container parts 25, 26 to each other, reference is made below to the Fig. 3, Fig. 4 and Fig. 5.

[0028] Fig. 3 illustrates a section of the top side 21 of the transport unit 11 in the region of an opening 38 through which the upper end of the container part 26 extends. The top side 21 is preferably made of corrugated sheet metal, which is rigid due to its shape. In the region of the opening 38, the integrity of the top side 21, i.e. of the corrugated sheet metal, is interrupted. For stiffening purposes, the opening 38 is surrounded there by a profile element 39 arranged transversely to the waves of the corrugated sheet metal. The profile element can be designed as an angle profile. Irrespective of this, the profile element can extend around the entire opening 38. The profile element 39 can be connected to the corrugated sheet metal forming the top side 21 via weld seams. At least part of the weld seam 40 is arranged on the side of the profile element 39 facing the opening 38.Additionally or alternatively, a weld seam 41 can be arranged on the side of the profile element 39 facing away from the opening 38.

[0029] If the profile element 39 is designed as an angle profile, it has a vertically oriented leg welded to the upper side 21 and a preferably horizontally oriented leg 42 pointing away from the opening 38. This leg 42 is provided with holes 43 for fastening a flange element 44.

[0030] The flange element 44 is screwed to a radial flange 45 of the container part 26. The radial flange 45 is preferably oriented away from the container part 26 towards the profile element 39. The radial flange 45 preferably ends at a distance D from the profile element 39. This distance D is bridged by the flange element 44. With its leg 46 pointing radially outwards, i.e. towards the upper side 21, the flange element 44 rests on the horizontal leg 42 of the profile element 39 and can be screwed or welded to it. If a welded connection is provided, however, only a flat profile can be used for the profile element 39 instead of the angle profile, so that the horizontal leg 42 is omitted. The flange element 44 can then be welded directly to the vertical section of the profile element 39.

[0031] The flange member 44 also has an inner portion 47 extending into the container, which, as shown in Fig. 5, may be designed to be offset. At its inner end, it may be horizontally oriented and provided with fastening openings to accommodate fastening bolts 58. The flange element may be designed as a one-piece ring whose shape corresponds to a horizontal section through the container 24. Alternatively, it may be composed of several sections that together form an annular element.

[0032] The upper container part 25 is connected in a similar manner to the underside 22 of the second transport unit. This in turn has an opening 48 through which a lower section of the container part 45 extends. The opening 48 is surrounded by a profile element 49, which can be designed and arranged as a mirror image of the profile element 39 with respect to a horizontal plane. For example, the profile element 49 can be designed as an angle profile or as a flat profile. The profile element 49 can be connected to the underside 28 via a weld seam 50 facing the opening 48 and / or via a weld seam 51 lying on the opposite side. The profile elements 39, 49 are bent towards one another at the inner sections 47, 57, so that on the one hand they lie flat on one another on the inside and on the other hand they are located at a vertical distance from one another in the middle and on the outside.

[0033] The profile element 49 can extend in one piece or in sections around the entire opening 48. It can have a leg 52 pointing away from the opening 48 and thus be designed as an angle profile. Alternatively, such a leg 52 can be omitted. The profile element 49 is then a flat steel bar. Similar to the profile element 39 with the top side 21, the profile element 49 can be connected to the bottom side 22. With regard to its welded connection to the bottom side 22, the explanations given for the profile element 39 apply analogously.

[0034] With the profile element 49, for example, the Fig. 5, by means of a flange element 54, an outwardly directed radial flange 55 of the upper container part 25. The flange element 54 has an outwardly directed section 56, which connects the horizontal leg 52 to the radial flange 55 of the container part 25 and in turn bridges a distance between the outer end of the radial flange 55 and the profile element 49. In addition, the flange element 54 can have an inwardly directed section 57, which Fig. 5, can be formed with an obtuse-angled crank and rests with its horizontal end on the horizontal end of the inner portion 47 of the flange element 44. Connection can be effected by a series of screws 58 forming a ring extending around the interior of the container. The screws can be covered by individual cover elements 59, which, when connected to one another, form a ring extending along the inner circumference of the container 24 to reduce dust accumulation.

[0035] The flange elements 44, 54 can, as Fig. 6, can also be designed with a right-angled offset. A vertically oriented section is then present between the horizontal sections of the flange element 44, 54.

[0036] Further modifications are possible. For example, the flange elements 44, 54 can be designed Fig. 6 as well as the embodiment according to Fig. 5 have alignment means arranged within the container 24. The latter shows Fig. 7. For this purpose, one of the flange elements, for example the flange element 54, has an angled section 57a ​​that overlaps the other flange element 44. This section 57a ​​can extend along the entire inner circumference of the flange element 47. It can, as in Fig. As shown in Figure 7, the flange element 47 can be flush with the bottom or extend further downward. In the latter case, the cover element 59 is omitted.

[0037] For pre-assembly at a workshop, e.g., an assembly plant, the housings 15, 16 are first prepared, for example, as shipping containers, and provided with the necessary openings, such as openings 38, 48. Profile elements 39, 49 are placed around openings 38, 48 and welded to the top side 21 and bottom side 22, respectively. This provides particularly good accessibility, especially for the weld seams 40, 50. If necessary, the weld seams 41, 51 can be additionally or alternatively applied to the opposite side of the profile elements 49, 59, either over the entire length of the cut corrugated profile or just over partial lengths.

[0038] For further assembly, the container part 26 is placed in the first transport unit. The container parts 26, 25 may have been previously screwed to the flange elements 44, 54. However, this can also be done after the container part 25, 26 has been placed in the respective opening 48, 38. Once the container parts 25, 26 have been positioned in this way, the leg 42 can be screwed to the outer section 46 and the leg 52 to the outer section 56. The profile elements 44, 54 form a connecting element 60.

[0039] It is pointed out that the first container part 26 and the further container part 27 can also be connected by a corresponding connecting means 61, which corresponds to the connecting means 60 according to Fig. 5 corresponds.

[0040] The connecting means 60, 61 described so far offer a reliable, secure, and easy-to-assemble option for assembling several partially pre-assembled system components, which have vessels extending over at least two transport units 11, 12. Such a vessel is, for example, also a silencer housing 62 of the silencer 30, which consists of a lower sub-vessel 63 located in the first transport unit and a second sub-vessel 64 housed in the second transport unit 12. The sub-vessel can be provided with a closable access opening 63a to provide a technician with access to the interior of the silencer 30.

[0041] Other connecting means may be arranged between further parts of the systems described so far, such as connecting means 65 designed in the manner of sliding or plug-in sleeves for the pipeline 28 or at the man transitions 36, 37. These connecting means fit into one another when the transport units are stacked without any special measures.

[0042] Similar plug-in sleeves 69 can be arranged between the transport units 11 and 14 to create a passage for lines to be installed. These can be, for example, electrical lines, fluid lines, or the like. The necessary lines, e.g., the electrical line 70, can be pre-assembled in one of the transport units, e.g., connected at one end, kept ready, and routed through the plug-in sleeves 69 and connected after the transport units 14, 11 are stacked.

[0043] At the man crossings 36, 37, flaps 66 (and 67 in the corresponding first transport unit according to Fig. 2) to ensure safety for the personnel entering the respective transport unit 11 or 12. The ladder 35 can be used to transfer from one transport unit 11 to the other transport unit 12. The ladder 34 in the further transport unit 14 can be used to transfer to the first transport unit 11. The transport unit arranged at the bottom can have an access hatch or according to Fig. 2 have a door 68. The stacked transport units 14, 11, 12 thus form a building that can be transported in parts to the assembly site and completed and put into operation there with little installation effort.

[0044] After assembly of all components, the transport units 11, 12 (and / or 14) are ready for transport and are transported in this state to the assembly site. At the assembly site, the transport units to be used, e.g., the transport units 11, 12, are stacked one on top of the other. This applies to both the embodiment according to Fig. 1, as well as for the embodiment according to Fig.2. When placing the transport units 11, 12 on top of one another, the transport units 11, 12 are positioned relative to one another by their corner fittings 19a, 19b and, if applicable, spacers 20 arranged between them. The inner sections 47, 57 of the flange elements 44, 54 also rest on one another. Due to the distance D between the outer flange 45 and the profile element 39 and the outer flange 55 and the profile element 49, height differences can be somewhat compensated and static overdetermination can be avoided. Likewise, the offset, inward-facing sections 47, 57 can yield slightly. Should a small gap remain between the inner ends of the flange elements 44, 54, this can be tightened using the screws 58.

[0045] The outwardly directed radial flanges 45, 55 and the associated flange elements 44, 54 form a connecting means with which the container parts 25, 26 can be connected in a sufficiently fluid-tight manner at the installation site by a technician from the inside of the container 24. Access to the intermediate space 23 is not necessary.

[0046] The system 10 according to the invention comprises at least two transport units 11, 12, which have assemblies spanning the transport units, in particular the containers (24, 39, 62) spanning the transport units, which are divided into sub-housings 25, 26 according to the subdivision specified by the transport units. Preferably, all interfaces of containers spanning the transport units are arranged in an intermediate space 23 between the upper side 21 of the lower transport unit 11 and the underside 22 on the upper transport unit 12. This intermediate space is preferably too narrow to allow access after the two transport units have been stacked. Flange elements 44, 54 pre-assembled on the container parts and the transport units establish the connection between the container parts 25, 26 and the transport units 11, 12, as well as enable final assembly from the container interior.The invention thus enables extensive pre-assembly of the transport units and fast, safe and efficient erection of the system at the installation site.
