Description

The invention relates to a rotary heat exchanger set and a corresponding rotary heat exchanger and method for producing a rotary heat exchanger.

A rotary heat exchanger is for example off EP 2 520 890 A1 known. Such rotary heat exchangers are preferably used for heat recovery (or "cold recovery"). For example, in a conventional rotary heat exchanger through a portion of a storage mass warm exhaust air can be blown, which transfers heat to walls of flow channels within the storage mass. Upon further rotation of the storage mass the heated channels reach an area in which the flow channels can be acted upon with cold outside or fresh air, and the warmed channel walls give the absorbed energy to the flowing outside air and thereby cool themselves off. Usual heat wheels (rotating storage masses) can have diameters of several meters. As a result, the assembly is usually very complex. Especially with larger rotary heat exchangers while the items of the rotary heat exchanger are often delivered to several pallets to the site. There then takes place the assembly. The heat wheel (the rotating storage mass) is pieced together, ie individual circle segments are provided and successively fastened together, so that the heat wheel can be built. Optionally, even the individual circle segments may again be subdivided into individual circular ring segments, which are successively joined together to produce a single circular segment. The effort on the site, especially time, is correspondingly high. For a heat exchanger wheel with a diameter of five meters, the time required for installation on the construction site is more than two days with at least two installers ("master craftsmen").

It is an object of the invention to provide a rotary heat exchanger and a method for producing the same, wherein, especially when using comparatively large heat wheels, a simple and in particular rapid assembly can be done on site.

This object is solved by the features of claim 1.

In particular, the object is achieved by a rotary heat exchanger set, comprising a first, in particular lower, module and a second, in particular upper (compared to the first module separately present) module, wherein the first module comprises a first heat wheel part of a heat wheel and the second module second Wärmeradteil the heat wheel comprises, wherein the first and second part (at least approximately) form the entire heat wheel.

A core idea of the invention is to prepare a rotary heat exchanger set. This set comprises two modules, which in turn (in one assembly) form the entire heat wheel (at least approximately). Such a modular design makes it possible to considerably reduce the time required for assembly on the construction site (by at least a factor of 5). In particular, the elaborate attachment of individual (cake piece-like) circle segments which has been carried out hitherto has been eliminated. According to the invention, it was also recognized that these advantages, possible disadvantages or difficulties, which predominate with a modular design of the rotating heat wheel. In conventional heat wheels, which represent rotating parts, there are certain difficulties that due to the rotatable mounting a "simple halving" is not possible. In this respect, a particular inventive idea is also not to provide a (lower) module, then successively (as described above) individual circular segment-like Wärmeradabschnitte be added, but two modules form, then together (at least approximately) define the entire heat wheel , The first module is preferably a lower module, the second module is preferably an upper module. A lower module means a module that is configured so that it can be placed on a subfloor at the installation site in such a way that the corresponding upper module can be mounted on the lower module. A separation surface between the upper and lower module is then preferably horizontal. Alternatively, the two modules can also be arranged next to each other, such that a separating surface extends (at least substantially) vertically (in the assembled state). In general, a separation surface between the first and second module is preferably parallel to an axial direction.

First and second part should form at least approximately the entire heat wheel (in the assembled state), which preferably means that at least 80%, in particular at least 95% or 100% of the heat wheel is formed by the two modules. Each module is a unit in itself, and consists of interconnected (connected) parts. However, the second module is provided separately from the first module, so there are no connections (possibly of packaging or protective devices or the like. Apart) provided between the two modules between the first and second module. Preferably, an at least approximate design of the entire heat wheel is to be understood that the cavity volume defined by the two heat wheel parts (ie the volume of the individual flow channels) represents at least 80%, preferably at least 90% or 100% of the total void volume of the (assembled) heat wheel. Alternatively or additionally, an at least approximate design of the entire heat wheel is preferably to be understood as meaning that the total weight defined by the two heat wheel parts represents at least 80%, preferably at least 90% or 100% of the total weight of the (assembled) heat wheel.

The first module preferably comprises a first housing part (a frame housing). The second module preferably comprises a second housing part (of the frame housing). First and second housing part can (at least approximately) form the entire frame housing. An at least approximate design of the entire frame housing is preferably to be understood as meaning that first and second housing parts define at least 80%, preferably at least 90% or 100%, of the total weight and / or the internal volume defined by the frame housing. First and / or second housing parts may each define 40%, preferably 45% or (approximately) 50% of the total weight of the frame housing or the internal volume of the frame housing.

A frame housing is preferably to be understood that component in which (in the assembled state) the heat wheel is received (and stored). Correspondingly, the first housing part is preferably the part in which the first heat wheel part is accommodated and the second housing part is that part in which the second heat wheel part is accommodated. By dividing the heat wheel parts and housing parts on the two modules overall a particularly simple rotary heat exchanger set is created, which allows mounting (assembly) of the rotary heat exchanger on site in a short time.

First and / or second module may comprise at least one holding device (in particular at least one lifting eye) for lifting the respective module, in particular by a crane. Further preferably, at least two holding devices (lifting lugs) are provided on the first and / or second module. In any case, it is thereby made possible that the (entire) first or second module can be lifted, in particular by a crane, so that the two modules spent in the simplest case exclusively by providing and operating the crane to their installation site and arranged on top of each other can be. A particular advantage is then that in a mounting on a roof (where either no appropriate transport facilities, such as forklift can drive or this is at least significantly more difficult) in a simple and fast way yet only a few modules are built and assembled can.

First and / or second module are preferably configured so that they can be transported in a vertical orientation (possibly only in a vertical orientation). Transportability in a vertical orientation is to be understood as a structural feature in this context. In this context, it is significant that conventional heat wheels do not (compulsorily) allow transport in the horizontal state due to their geometry and in particular size. Due to the forces occurring during folding (for example, shear and / or torsion forces), a module can be destroyed during a transfer (or a transport in a horizontal orientation). In order to detect whether a corresponding first and / or second module has been folded over or transported horizontally (or stored), at least one corresponding sensor may be provided which is selected for detecting such a folding, for example a shock sensor. Such a sensor may optionally indicate by a display (eg color coding) whether a transfer has taken place.

The heat wheel preferably has a diameter of at least 2.00 m, more preferably at least 2.50 m, even more preferably at least 4.00 m. Especially with large heat wheels, the effects described above (in particular the time savings) are particularly pronounced.

The first module may comprise at least one pivot lock for locking a pivoting movement of the first heat pad part relative to the first housing part. Furthermore, the first module may comprise at least one securing device for securing the first heat pad part from falling out of the first housing part. Also, the second module may comprise at least one pivot lock for locking a pivoting movement of the second heat pad relative to the second housing part and / or at least one securing device for securing the second heat pad against falling out of the second housing part. In general, it should be noted that (in particular when transported in a vertical orientation), for example, the second module can basically fall out of its associated second housing part, since it may not be secured (as in the assembled state) by the rotatable mounting or the respective other module is. For example, if the first Module is already built (as a base) on the site and the second module is to be mounted on it, the second heat pad must if necessary be oriented so that it can fall out of the housing part down. However, this can be prevented by the at least one securing device. Such a securing device is then removed (preferably) at the end of assembly. The at least one securing device is thus (preferably) detachably formed by the first or second heat-wheel part and / or detachably formed by the first or second housing part. If necessary, it would also be conceivable for the securing device to remain on the first and / or second housing part, but be detached from the respective heat-loading part (for example pivoted away or moved in a translatory manner, possibly like a bolt). The at least one pivot lock of the first and / or second module facilitates both transport and installation on the construction site. In particular, this achieves the result that a module (eg, first module) which may possibly be pivoted in the associated housing part (eg, first housing part) and which can pivot due to the (rotatable) mounting, remains at rest. It is also true that such a pivot lock (as well as the above securing device) may be removed (at the end of assembly) (ie is detachable) or at least moved away from the first or second heat wheel part (pivoted away or translationally, in particular like a mirror). can be moved away). In particular, by the at least one anti-sway device and / or at least one securing device, the transport and in particular assembly on the construction site can be effectively performed.

The first and second modules are at least approximately the same size and / or at least approximately the same weight. Preferably, the respective (in comparison) smaller module has a size which corresponds to at least 80%, preferably at least 90%, of the size of the larger module (in comparison). The size should be defined here in particular by a volume which is defined by an envelope surface of the respective module. By at least approximately equal weight, a weight of the (in comparison) lighter modulus is to be understood as being at least 80%, preferably at least 90%, relative to a weight of the (in comparison) heavier modulus.

First and second heat pad are at least approximately the same size and / or at least approximately the same weight. Preferably, each of the (in comparison) smaller heat load part has a size which corresponds to at least 80%, preferably at least 90% of the size of the (compared to) larger heat load. The size is to be defined here in particular by a volume which is defined by an envelope surface of the respective heat load part. An at least approximately equal weight is to be understood as meaning a weight of the (comparatively) lighter heat-loading part of at least 80%, preferably at least 90%, relative to a weight of the (in comparison) heavier heat-loading part.

First and second housing part are at least approximately the same size and / or at least approximately the same weight. Preferably, the respective (in comparison) smaller housing part has a size which corresponds to at least 80%, preferably at least 90% of the size of the (in comparison) larger housing part. The size should be defined here in particular by a volume which is defined by an envelope surface of the respective housing part. By at least approximately the same weight, a weight of the (in comparison) lighter housing part of at least 80%, preferably at least 90% compared to a weight of the (in comparison) heavier housing part to understand.

Each (at least approximately) equal modules or Wärmeradteile or housing parts an effective transport and a quick installation is promoted.

A heat wheel axle is preferably formed by the first module (in particular completely). The heat wheel axle is preferably designed to be stationary relative to the housing or first housing part, so that the heat wheel rotates about the heat wheel axis. In operation, the heat wheel is therefore preferably rotatably mounted on the heat wheel axis. By assigning the Wärmeradachse, in particular the assignment of the complete Wärmeradachse to one (in particular the first, alternatively the second) module assembly on site is facilitated.

The first module may comprise a first (in particular partially hollow cylindrical or hollow cylindrical) bearing part for rotatable mounting on a (in particular the above) heat wheel axis. Alternatively or additionally, the second module may comprise a second (in particular partially hollow cylindrical or hollow cylindrical, preferably semi-hollow cylindrical) bearing part for rotatable mounting on the heat wheel axis. First and second bearing part preferably form (at least approximately) a hollow cylinder. A partial hollow cylinder is to be understood in particular as meaning a section of a hollow cylinder whose end faces are formed by a ring sector (which thus arises when a hollow cylinder is divided along a surface which is parallel to the cylinder axis). A semi-hollow cylinder is a hollow cylinder whose end surfaces are formed by a ring segment extending over an angular range of 180 degrees (or a structure that results when a hollow cylinder along a surface in which the hollow cylinder axis lies, is shared). As far as a cylinder or a cylindrical structure is mentioned, in particular a circular cylinder or a circular cylindrical structure is meant. Particularly preferably, one of the modules has a hollow-cylindrical bearing part and the other module has a partially hollow-cylindrical, in particular semi-hollow-cylindrical, bearing part. During assembly, this part-hollow cylindrical (semi-hollow cylindrical) bearing part can then be placed on the hollow cylindrical bearing part and connected thereto (for example screwed or welded). The hollow cylindrical bearing part can in particular be designed such that it has a portion which corresponds (mirrored) to the partially hollow cylindrical bearing part so that a homogeneous hollow cylinder (with constant wall thickness) is formed overall when the first and second modules are assembled. About such onion skin structure can be done quickly and effectively a reliable connection between the two modules in the storage area.

The first and / or second module preferably has a roller bearing, in particular ball bearings or nail bearings on. The rolling bearing is preferably arranged between the heat wheel axis and a (in particular the above-described), preferably hollow cylindrical, bearing part. In one specific embodiment, one of the modules (eg, the first module) already has the heat wheel axis (completely), as well as a rolling bearing mounted on the heat wheel axle (complete) and a hollow cylindrical bearing part. This hollow cylindrical bearing part is then preferably already configured so that a partially hollow cylindrical bearing part of the other (eg second) module can be attached. Overall, the assembly effort is reduced.

The first and / or second module may comprise at least one positioning element, in particular positioning pin. The positioning element (the positioning pin) preferably cooperates with another positioning element (in particular a positioning recess) on the respective other module in such a way that, when the first and second modules are assembled, the modules are fixed relative to one another. The at least one positioning element (positioning pin or positioning recess) can be arranged on the housing and / or on the heat wheel. A length of the positioning pin is preferably at least 3 cm, more preferably at least 5 cm. The at least one positioning element may have a thread (for the realization of a screw connection). Preferably, at least one positioning element is arranged in a hub region (on the hub). By means of the at least one positioning element in the hub region, a simple and particularly accurate positioning can take place. Alternatively or additionally, at least one positioning element may be arranged on a peripheral surface of the first and / or second heat-wheel-loading part (in particular for a rather coarse (pre-) positioning).

The heat wheel preferably has a plurality of spokes. Individual segments of the heat wheel can be connected to each other (in particular at the factory) by screwing the spokes. The connection of the first and second module (preferably on a construction site) is preferably carried out by connection (screwing) along (in relation to the entire heat wheel considered average) spokes.

The first and / or second heat pad part preferably comprises a plurality of segments (in particular separated by spokes), which are connected to one another, in particular screwed together, by (flat) strips, preferably flat steel, arranged on one end face or both end faces of the corresponding heat wheel part. Alternatively or additionally, the first and second heat wheel part are connected to one another by (flat) strips, preferably flat steel strips, arranged on one end face or both faces of the heat wheel parts, in particular screwed together. The strips preferably have a length which is at least 10 times as large as a width and / or at least 30 times as large as a thickness. The width of the strips can be at least 3 times as large as the thickness. Most preferably, the strips correspond to spoke covers that cover spoke edges.

The above object is further achieved by a rotary heat exchanger made by assembling the above-described set. The rotary heat exchanger is preferably configured for (in particular exclusively for) upright mounting.

The above object is further achieved by a method for producing a rotary heat exchanger set, in particular of the type described above and / or for the production of a A rotary heat exchanger of the type described above, comprising the steps of: assembling a first, in particular lower, module, and a second, in particular upper, module, wherein the first module comprises a first heat-wheel part of a heat-wheel and the second module comprises a second heat-wheel part of the heat-wheel, wherein first and second heat wheel part (at least approximately) form the entire heat wheel.

A second airflow 29 will be over the third channel 26 (coming from the opposite direction) to the rotary heat exchanger 10 guided and after passing through the rotary heat exchanger 10 over the fourth channel 27 dissipated.

The warmer of the air streams 28 . 29 gives heat to the heat wheel 20 from. This heat (or a part of this heat) is absorbed by the cooler air flow of the two air streams. This transfers heat from the warmer airflow to the cooler airflow. Depending on the circuit, heat or cold can be recovered.

The heat wheel 20 has a variety of Wärmeradkanälen 30 on, through which the air can flow. The walls of the channels 30 are preferably made of aluminum or an aluminum alloy.

In particular, on the construction site, then the two heat wheel spare parts 14 . 16 be mounted together. Positioning elements are used for positioning 39 (Positioning pins) provided over which a position of the first and second heat pad against each other, at least roughly, can be set. At the same time, you can use the positioning elements 39 if necessary, a screw connection can be realized (these may preferably have a thread). For exact positioning are then in particular positioning 51 (Positioning pins, preferably threaded for the realization of a screw) provided in a hub area (see 6 ).

In 5 is the heat wheel 20 shown in assembled condition.

In 6 is a (central) section of the heat wheel 20 (or the Wärmeradteile 14 and 16 ) shown enlarged. How to recognize there is the first part of the heat 14 or according to the first module a Wärmeradachse 40 assigned. Furthermore, the first heat wheel part 14 a rolling bearing 41 and a first bearing part 42 on. The first bearing part 42 forms a hollow cylinder and is for receiving a second bearing part 43 of the second heat load part 16 educated. The second bearing part 43 forms a semi-hollow cylinder.

In 7 is a further enlarged section of the heat wheel (or the first and second heat pad) shown. In particular, there is again the positioning 39 recognizable. Furthermore, straps 45 recognizable, together with the (can be connected) tether brackets 46 contribute to the cohesion of the heat wheel (in the assembled state). The assembled state is (partial) in 8th shown.

In 9 and 10 is again shown in a side view of the onion-bowl-like structure of the storage of the heat wheel.

In 11 is a section analogous 6 shown, but with a different configuration of storage. In 6 becomes the second bearing part 43 over on an inner peripheral wall 50 the positioning elements acting as fastening devices 51 (Screws) with an outer peripheral wall 52 of the first bearing part 42 connected. In 11 a connection of the second bearing part takes place 43 with a (ring) disc 53 , in turn, the first bearing part 42 is assigned, or is part of the first module. The disc 53 is (already within the rotary heat exchanger set) fixed to the first bearing part 42 connected (for example screwed). Furthermore, the embodiment differs in sections in 11 is also represented by the fact that the number of individual segments is higher here (in concrete terms, each module has six ring segments here).

It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art,
