Description

The present invention relates generally to industrial media conditioning apparatus according to the preamble of claim 1 and to a system of several such apparatus.The present invention also relates to devices for conditioning combustion air which is supplied to gas turbines. The combustion air of gas turbines is cleaned of solid and liquid particles in so-called filter houses in order to subject the working machine to as clean air as possible. For this purpose, droplet separators, bird protection grids and usually one or two filter stages are installed in such an air filter house. Since the filters and the compressors of the gas turbine tend to ice under given external air conditions-high relative humidity and temperatures around the freezing point-the air is additionally preheated in this season. For this purpose, heat exchangers, infrared radiators or hot air or rare exhaust gas distributors are also installed in a filter house, which heat the intake air indirectly or directly. Such a device 1 according to the prior art is illustrated purely schematically in FIG. 1, wherein the anti-icing system 2, the weather protection grid 3, the grid 4, the prefilter wall 5, the fine filter wall 6, the protection grid 7, the transition piece 8, the slotted link muffler 9 and the inlet air duct 10 and the gas turbine 11 can be clearly seen. It is essential that filter houses of gas turbines are practically always individually adapted to the respective application and installation site and manufactured individually or only in small series. This is associated with a high design outlay and long delivery times.As a result, an optimum with respect to flow and pressure loss is hardly achieved. A high flow velocity causes a high pressure loss. Air filters with non-uniform inflow are soiled more quickly. A small number of air filters also leads to a more rapid contamination and to a large increase in the pressure loss. A high pressure loss in the filter house causes corresponding losses in performance of the gas turbine. The contaminated filters may have to be replaced during operation of the gas turbine under unfavourable conditions. An air filtration having only one or two stages leads to an increased introduction of dirt into the compressor of the gas turbine. This dirt deposits on the compressor blades (fouling) and likewise leads to increasing losses in performance and efficiency.It is therefore likewise customary to wash the compressor of the gas turbine during operation (online) or in the shut-down and cooled state (offline). For this purpose, suitable washing solution is introduced into the compressor under high pressure using special washing devices and the baked-on dirt is washed off again and rinsed out. In online washes, the power of the gas turbine usually has to be lowered. In offline washes, the gas turbine goes completely out of operation for many hours. Both reduce the availability of the gas turbine as a drive of an electric generator or a gas compressor and thus the yield of the operator.As the intake air temperature increases, the performance and efficiency of the gas turbine decrease. To compensate for this, the intake air is cooled in summer. Direct or indirect methods are also used for this purpose. Direct cooling is possible by the evaporation or injection of water into the intake tract and the associated adiabatic cooling effect. The intake air can be cooled indirectly by heat exchangers which are acted upon by naturally or artificially cooled heat transfer media.To improve air filtration, it is known to filter the combustion air for gas turbines in three stages. However, this already leads from the beginning to an increased pressure loss with the already described consequences. The filter elements are transported during their change under difficult conditions via ladders or with cable winch.Furthermore, it is known to condition the combustion air for gas turbines in a hybrid manner. For this purpose, the combustion air is either heated dry or humidified by a hybrid cooler, or simultaneously heated and humidified (DE 10 2004 050 182 A1). It is also known to combine these method steps in a filter house. Thus, the combustion air of the gas turbines can first be roughly filtered in a first filter stage, then conditioned in a hybrid cooler and subsequently filtered finely and very finely in two further filter stages.The disadvantage of this solution is that it consists of two filter house halves before and after the hybrid cooler. This leads to enormous assembly effort at the construction site, because the parts can always only be moved individually with a crane. Furthermore, connecting flanges or flexible compensators are required between the individual components. The parts through the trough under the hybrid cooler are also of different height, so that there are steps in the foundation or the support. To achieve larger air throughput quantities, several modules are required, which are placed one above the other on the construction site. The hybrid coolers require a special traverse for their lifting, which has to be delivered separately and carried away again. The hybrid coolers are air tight to one another to avoid untreated air bypass flows.The low air velocity required of the hybrid coolers to prevent drop discharge results in a low pressure loss of the hybrid filter house despite coupling with a three-stage air filtration. However, this results in an intake surface of about twice as large and a filter house of about three times as large as usual. This is associated with a correspondingly higher weight, which makes conversion to the novel method more difficult and requires corresponding sub-constructions.For larger gas turbines, more than 10 of the hybrid coolers listed would be required. Difficulties arise in combining these in an air filter house in a meaningful manner. Thus, a maximum of 3 hybrid coolers can be stacked one above the other without changing the statics of the cooler housing.A gas turbine filter house (WO 2003 / 028852 A1) made of stackable frame modules is known for transport, its dimensions being adapted for insertion into standardized freight containers which are not suitable for large-scale conditioning.Air conditioning apparatuses for the air conditioning of air streams in buildings are likewise known. Here too, air is filtered, heated or cooled and moistened or dehumidified, depending on the climate situation and requirements of the supplied premises (e.g. DE 44 07 806 A1). However, these devices are not standardized worldwide, cannot be stacked or are suitable for larger amounts of air. Gas turbines, in turn, do not require the complete functionality of air conditioning compact devices.Also known are unit containers not suitable for larger air quantities, with air conveying devices (U.S. Pat. No. 63 89 847 B1), as well as a modular evaporative humidification unit with a structure not independently stackable (U.S. Pat. No. 5,289,696 A) with reinforcing elements that narrow the flow cross section.The object according to the invention is therefore to provide a device for industrial media conditioning which can be prefabricated as far as possible industrially and can easily be adapted to different application cases and installation locations. The transport and assembly effort should be kept low. The device should in particular be able to be coupled particularly easily to a system of such devices.This object is achieved with a device according to claim 1 and a system according to claim 25.The device according to the invention for the industrial conditioning, in particular cleaning, moistening, drying, cooling, heating and / or increasing the pressure of liquid and / or gaseous media, has at least one conditioning device (e.g. filter, humidifier, heat exchanger, dryer, etc.) and a container which forms the housing of the device and a flow channel for the medium, so that a cross section of the container is substantially flowed through by the medium, wherein the container is formed self-supporting and stackable for the storage, transport and / or for the function of the device, wherein the container (21) is a container and is formed substantially closed at least in a circumferential direction. As a result, these devices for industrial-scale media conditioning can be stored, transported and combined into systems in a particularly simple manner, without the need for special preparations, such as cross members during transport or measures regarding construction during storage. This also eliminates the disadvantages of known devices which were composed of several individual modules and which had to be assembled only at the site of assembly. The device can now be prefabricated from standardized segments at the factory, transported to the construction site and there be assembled and arranged in any modular manner within a very short time.The devices become standardized in this manner. The manufacture can be carried out industrially. Delivery times are shortened. The cost is reduced. The devices are always of identical dimensions and have a uniform, appealing appearance. They can be arranged in different space-saving constellations. If necessary, individual devices can also be replaced quickly by new ones, so that no long downtime arises.By integrating the individual elements of the device into a single housing, it is also possible to reduce not only the dimensions of the device, but also the weight thereof.It is advantageous here that the container is substantially closed at least in a circumferential direction. The container then forms a flow channel for the medium which runs through in one direction, i.e. it offers little flow resistance to the medium itself. However, alternatively (not claimed) it can also be provided that the flow channel intentionally changes direction, for example is guided through two adjacent sides of a rectangular container. This can be advantageous, for example, when the container is set up or when many devices are arranged in a system, the passage of media in one direction is not possible.Particularly preferably, the container is designed as a container according to DIN ISO 668 with respect to its length, width and height. Such containers have been standard for many years and there are great experiences in their transport, storage and stacking. In particular, these containers are designed for large loads which such a container must necessarily carry in a device for large-scale media conditioning. The container is expediently designed as a container with respect to its corner fittings, in particular according to DIN ISO 1161.It has already been known to use unit containers which use the advantages of container construction in order to accommodate units such as pumps, compressors, combined heat and power stations, water treatment systems, etc. in massive and simultaneously mobile enclosures, to pre-assemble them completely at the factory, to test them, to transport them in one piece to the construction site and to place them very quickly, wherein the container thus serves simultaneously or successively as a packaging, standardized transport container and mobile enclosure. However, these devices were not devices for industrial-scale media conditioning, and these containers are in each case not a container which forms the housing of the device and a flow duct for the medium, with the result that the medium flows through a cross section of the container.It has now surprisingly been found that the advantages of the containers can advantageously also be used for industrial media conditioning, wherein the stability of the container despite the provision of a flow channel is still provided to the extent that self-supporting and stackable storage and transport remain ensured.If one or more stiffening elements are provided in the container for protection against the action of internal and / or external pressure, a particularly large number of devices can be stacked over one another and the devices must also be handled less carefully during transport. The reinforcing elements are preferably formed by one or more angular, in particular triangularly shaped, elements, wherein in particular one side of the elements is arranged on in each case one side of the container and the elements of adjacent sides of the container adjoin one another. This allows particularly simple and cost-effective stiffening to be achieved.Advantageously, at least one heat exchanger is provided. The medium can then be subjected to heat or heat extracted from it. Furthermore, at least one secondary media transmitter is advantageously provided. Then, for example, the heat of the medium can be dissipated to a secondary medium for further use. Preferably, it is provided here that at least one heat exchanger and / or a secondary media exchanger, in particular combined, are designed as hybrid heat exchangers. In this case, the secondary medium exchanger can simultaneously also assume the function of the heat exchanger in that the secondary medium transfers heat / cold / energy, for which it circulates through the secondary medium exchanger and is optionally supplemented externally and reheated and / or cooled or regenerated. It can likewise be provided that the secondary medium is in mass transfer with the main medium (e.g. itself evaporates / evaporates into the medium to be conditioned or absorbs moisture or dust or the like from the medium to be conditioned). Furthermore, it can be expediently provided that a secondary media exchanger or a hybrid heat exchanger can be operated with a secondary medium, for which a secondary media circuit is formed, wherein preferably one or more secondary media feeding and / or receiving devices, and in particular also at least one secondary media pump and a heat exchanger, a discharge and / or a secondary feed valve are arranged in a secondary media circuit. As a result, the secondary media circuit can be maintained particularly easily. Advantageously, a secondary media recording device is designed as a collecting trough and in particular provided with a cover that can be walked on, in particular with a grid. This element of the secondary media circuit can then be integrated into the device in a particularly space-saving manner.Particularly preferably, one or more coarse protection devices are provided on the inlet side in the device, in particular for protection against major contaminants, which for example provide protection against groundwood and / or birds and / or also against special weather influences, such as rain, snow or hagel.In an advantageous development, at least one filter device, in particular two or three filter stages arranged in series in the flow direction of the medium, in particular of uniform or different filter methods (e.g. a combination of surface filter and adsorption filter or absorption filter alone, etc.), are provided. Preferably, the filter device is arranged in one of the enclosing walls of the container lying in the flow direction or in the walls inside the container completely closing off the flow path. Expediently, the filters of the respective filter devices are arranged one or more, in particular four, rows one above the other.In a further preferred embodiment, one or more devices which increase the pressure of the flowing medium are arranged in the apparatus, namely in particular in one of the enclosing walls of the container which lie in the flow direction or in walls which completely close off the flow path within the container. Such devices that increase the pressure of the flowing medium can be fans, compressors and / or pumps, for example. Instead of one device, a plurality can also be provided, i.e. a plurality of small fans, for example, instead of one large fan.A device for preventing icing is also expediently provided.Particularly advantageously, the conditioning devices, in particular the filters of the filter devices, the heat exchangers, the secondary media exchangers and / or the hybrid heat exchangers or anti-icing or pressure-increasing devices, are arranged in respective receptacles which are in particular designed such that they additionally stiffen the container. This also improves the storage and transport conditions. At the same time, however, the requirement for the container with regard to its stiffness can also be reduced. In other words, the container of the device can either be self-supporting and stackable on its own or can only acquire these properties in cooperation with the further devices of the device for industrial media conditioning, such as the conditioning device or devices. It is therefore essential that the container of the present device according to the invention does not already have to be self-supporting and stackable on its own.In particular for maintenance purposes, the container can have at least one laterally arranged antechamber in which no media conditioning takes place, which is connected via at least one opening which can be closed off in a sealed manner to a space in which the media conditioning takes place. The closeability ensures that the media conditioning is not disturbed. The medium then does not flow through this antechamber, so that this part of the cross section of the container does not form a flow channel.In an advantageous embodiment, the container of the device and / or at least one antechamber has at least one in particular closable opening in the ceiling and / or the floor and / or in particular in at least one other wall. Thereby, the spaces of two or more devices can be connected to each other.Preferably, at least one antechamber has at least one riser. This makes it easy to reach the clearances of stacked devices. Alternatively or additionally, it can be provided that at least one packing, preferably on a riser ladder, is arranged in a front space, which packing is designed in particular to accommodate a plurality of filter elements, in particular corresponding to the number of filter rows arranged above or behind one another in the filter devices. As a result, the devices can be maintained particularly comfortably. Instead of the filter elements, it is of course also possible to transport other elements of the apparatus and their devices easily with the elevator.Particularly expediently, the apparatus, a heat exchanger, a secondary medium feed device or a hybrid heat exchanger and / or an anti-icing device can be charged with antifreeze. For the device as such, this is particularly expedient if a liquid medium is passed through the device.Preferably, devices are provided for measuring the humidity and / or the temperature and / or the pressure as well as the fill level or the conductivity and / or other quality parameters to be adjusted of the gaseous and / or liquid medium to be conditioned and / or of a secondary medium before, on and / or after the individual conditioning stages. And in particular, at least one control or regulating and / or monitoring device is provided, in particular for the cleaning, moistening, drying, cooling and / or heating or preventing icing and / or the increase in pressure of the gaseous and / or liquid medium to be conditioned or of a secondary medium. The media conditioning can then be regulated and monitored particularly easily.Independent protection is claimed for a system comprising a plurality of apparatuses according to the invention, wherein a plurality of apparatuses are arranged one above the other and / or next to one another, which apparatuses are preferably sealed off from one another at the points of separation, wherein in particular two to nine apparatuses are stacked one above the other in a tower-like manner. Due to the sealing, no already conditioned medium can escape from the system or non-conditioned medium can enter the system.Preferably, the devices are connected to one another at least mechanically. Alternatively, it may also be sufficient for the devices to be mutually fixed in position on account of their own weight.Particularly advantageously, a plurality of preferably adjacently arranged devices, in particular tower-like stacks with devices, preferably supplemented with corresponding lower and / or upper covers or lateral walls, form a closed region around an inflow and / or outflow opening. In this case, a common media conditioning can be carried out jointly via all the devices in a particularly simple manner.In an expedient configuration, the pipelines are hydraulically connected to one another, in particular for the purpose of replenishing and / or emptying the secondary media exchangers and / or hybrid heat exchangers of the individual apparatuses, via collectors. In this way, the guidance of the secondary media can be configured uniformly and thus jointly controllable.Preferably, the flow and return collectors, in particular the heat exchangers and / or hybrid heat exchangers of the individual devices, are hydraulically connected to one another, preferably in the Tichelmann system. In the Tichelmann system, the tubes are routed from the heat generator to the heat consumer and back in a ring configuration such that the sum of the lengths of the supply line and return line is approximately the same for each heat consumer. Short-flow heat consumers have a long return line and vice versa. The purpose here is that all heat consumers are exposed to approximately equal pressure losses and thus equal volume flows, i.e. equal heat flows, are established in the heat consumers, even if no control valves are used. This causes uniform heating of heat consumers located further away as well.The control or regulating and / or monitoring devices of the individual devices are expediently connected to one another using cables which conduct electrical current, light or media, preferably using bus systems, in particular electrically, optically or hydraulically.Preferably, the devices of a system, in particular one or more devices forming, for example, tower-like stacks, are connected on the media side via a collector, a funnel and / or a channel at least to a device arranged upstream and / or downstream in each case. Alternatively or additionally, one or more devices can also be connected to a device arranged upstream and / or downstream, such as gas turbines, buildings and the like.In a particularly preferred embodiment, the device according to the invention and / or the system according to the invention of at least one gas turbine, a fan, an air compressor, a building or similar units or devices are connected upstream and / or downstream and the heat transfer media of the heat exchangers, hybrid heat exchangers and / or of the devices for preventing icing can be supplied with energy, in particular with (waste) heat or cold or electrical energy from this unit or this device or its environment or return energy, in particular (waste) heat or cold, from the media stream to be conditioned into this unit or this device or its environment.In a further particularly preferred embodiment, the device according to the invention and / or the system according to the invention of at least one gas turbine, a fan, an air compressor, a building or similar units or devices are connected upstream and / or downstream and the secondary media circuits of the secondary media exchangers, hybrid heat exchangers and / or of the devices for preventing icing or other conditioning devices can be acted upon with substances / media or energy from this unit or this device or its environment or return substances / media or energy from the media stream to be conditioned into this unit or this device or its environment, inter alia for its reprocessing.Independent protection is also claimed for air guiding devices which can preferably be used with the device according to the invention and / or the system according to the invention. These air guiding devices have a container designed as a container and at least two side walls through which the air can flow at least partially. In addition, air baffles or the like can also be provided in the interior of the container in order to avoid turbulence in the corner regions of the container.The features, characteristics and advantages of the present invention will become apparent from the description of preferred exemplary embodiments below with reference to the drawings. The following are shown: FIG. 1 shows the prior art, FIG. 2 shows a device according to the invention in a front view, FIG. 3 shows the device according to the invention according to FIG. 2 in a first side view, on the section along the axis A-A, FIG. 4 shows the device according to the invention according to FIG. 2 in a second side view, on the section along the axis B-B, FIGS. 5 a, b show a system according to the invention comprising devices according to the invention according to FIG. 2 in a first embodiment, FIGS. 6 a, b show a system according to the invention of devices according to the invention according to FIG. 2 in a second embodiment, FIGS. 7 a, b show a system according to the invention made of devices according to the invention according to FIG. 2 in a third embodiment, FIGS. 8 a, b show a system according to the invention of devices according to the invention according to FIG. 2 in a fourth embodiment, FIGS. 9 a, b show a system according to the invention comprising devices according to the invention according to FIG. 2 in a fifth embodiment, and FIG. 10 shows a system according to the invention comprising devices according to the invention according to FIG. 2 in a sixth embodiment.FIGS. 2 to 4 show the device 20 according to the invention purely schematically in a preferred embodiment frontally and in two side views. This device 20 is an industrial-scale device 20 for conditioning the combustion air of gas turbines (not shown, similar to FIG. 1 ). The device 20 has a container 21, wherein the container 21 is formed along its length in the circumferential direction with closed side walls 22, 23, 24, 25. The container 21 is designed as a 40' container 21, i.e. it has the essential structural details of such a container and thus also its dimensions (height 2591 mm, width 2438 mm, length 12192 mm). The two side walls 26, 27 along the length of the container 21, on the other hand, are substantially open in such a way that they form a flow channel 28 for the combustion air (the direction of the flow of the combustion air is indicated by arrows in all figures), as a result of which the combustion air flows substantially through the longitudinal cross section of the container 21. The only part of the cross section of the container 21 through which flow does not take place is the front chamber 29, which is arranged laterally behind the side wall 25 and has two tightly closable openings in the form of doors (only schematically indicated with a cross in each case) in relation to the actual conditioning chamber 30. In contrast to, for example, conventional building air conditioning devices, where these devices are flowed through in the longitudinal direction, the device 20 is flowed through in a transverse direction, whereby the filter area is advantageously increased and thus the flow resistance and the number of required devices 20 are reduced.The device 20 furthermore has three filter rows 31, 32, 33, and a heat exchanger 34, which is designed as a hybrid heat exchanger 34 and is arranged between the first 31 and second filter row 32. In front of the first filter row 31 is arranged a rain deflector with bird protection grille 35. In the floor 24 of the container 20 there is arranged a trough 36 which is covered with a movable grid 37. The filter rows 31, 32, 33 have a multiplicity of filter elements 38 which are arranged in the filter rows in a matrix-like manner (in the present case 17.times.4 filter elements 38) in suitable holding devices 39. By adapting these holding devices 39, it is also possible to use different filter fabricates or to retrofit them at any time as desired.The hybrid heat exchanger 34 is used for cooling (or else preheating), has a feed line 34 aand a return line 34 band is fed with a heat transfer medium (cooling medium in the case of the present cooling) and dampening water as secondary media, wherein the dampening water runs via the hybrid heat exchanger 34 as in a grading mill, for which purpose corresponding water guides (not shown) are provided. For cooling or preheating, the heat transfer medium is guided through ribbed tubes 40 running substantially horizontally along the length of the container 21, which tubes are hydraulically connected to one another. These ribbed tubes 40 are acted upon by the combustion air stream and draw heat or heat the combustion air. The combustion air is simultaneously humidified via the dampening water and cooled adiabatically additionally or with a delay. The dampening water is collected in the trough 36 and from there is pumped back by means of a sniffing pump 41 in a replenishing line 42 and is redistributed on the hybrid heat exchanger 34 via water distribution channels (not shown). In the replenishing line 42, a conductivity meter 43, a quenching valve 44 and a replenishing valve 45 are also provided, used dampening water being quenched via the quenching valve 44 and fresh water being replenished via the replenishing valve 45 if the conductivity of the dampening water rises above a predetermined value and thus indicates the excess contamination thereof. The refeeding also takes place when the level in the water collection trough 36 has dropped due to evaporation. In the event of a risk of frost, the water-collecting tank 36 is emptied in the same way. In the case of a plurality of devices 20 stacked one above the other, the pipelines (not shown) for emptying and refeeding the individual devices 20 are connected to one another via collectors (not shown).Furthermore, the device 20 has a continuous operating step 46 in order to enable the operating personnel to maintain, and the front space 29 has doors 47 (floor securing doors) in the floor 24 and in the roof 22 at the height of the first 31 filter row, as a result of which the front spaces 29 of devices 20 stacked one above the other are jointly accessible. In addition, a riser ladder 48 is provided in the antechamber 29, on which a lift (not shown) can also be arranged. The riser ladders 48 of devices 20 stacked one above the other serve the personnel to increase the respective plane. The floor securing doors 47 or hatch-like covers in the gratings secure the required openings in the roofs 22 or floors 24 of the front spaces 29 against falling. The lift can be designed such that it can be moved across the riser ladders 48 of devices 20 stacked one above the other. With the lift, a plurality of fresh filter elements 38 can be simultaneously transported conveniently and at high speed up to their destination level, or dirty filter elements 38 can be transported down for disposal. Airtight doors (only schematically indicated with a cross in each case) lead from the front chamber 29 to the respective filter rows 31, 32, 33 upstream and downstream of the hybrid heat exchanger 34. In the removed state of the first filter row 31, the hybrid heat exchanger 34 can be cleaned from the front side. In the removed state of a filter element 38 of the second filter row 32, the space behind the hybrid heat exchanger 34 can be reached in order to clean or adjust the water distribution of the dampening water on the rear side, if appropriate via the continuous operating inlet 46.Finally, a return header 49 and a forward header (not shown) with the corresponding inlet and outlet connections for the heat transfer medium are arranged in the front space 29. In the case of a plurality of devices 20 stacked one above the other, the collectors 49 of all the devices 20 are connected to one another in the feed line 34 aand in the return line 34 b. Via the feed connection of the lower device 20, all hybrid heat exchangers 34 for anti-icing are acted upon with a heat transfer medium containing antifreeze. As a heat source for the anti-icing, waste heat of the gas turbine, for example that of the lubricating oil, is preferably used. The return 34 bof the upper device 20 is returned again via a separate collector. This allows uniform application of all devices 20 in the Tichelmann system (rule known from heating technology, connecting all consumers via forward and return flows with the same length) and a complete venting of all elements of the hybrid heat exchangers 34.The hybrid heat exchanger 34 additionally performs the function of a droplet separator and coalescer. However, these conditioning devices can also be physically retrofitted after the hybrid heat exchanger 34 in the direction of passage of the combustion air in order to further improve the separation function of mist and droplets, which will not be necessary in most cases, however, since hybrid heat exchangers 34 operate reliably without steam.For controlling the wetting functions, the device 20 has a switch box 50. Differential pressure measuring devices (not shown) are installed for measuring the differential pressure of the individual filter rows 31, 32, 33 and, if applicable, also of the hybrid heat exchanger 34. The degree of contamination can be deduced from the differential pressure measured values and, in the case of a sharp increase, measures for replacing the filter elements 38 can be planned. For measuring the air temperature and the relative humidity before and after the hybrid heat exchanger 34, corresponding measuring devices (not shown) are likewise installed. If the air temperature upstream of the gas turbine falls below 5° C., the humidification of the combustion air goes back into operation off operation, above approximately 7.5° C.The device 20 now conditions combustion air for a gas turbine on an industrial scale, wherein the air passes through the rain deflector and the bird protection grid 35 and is cleaned via the first filter row 31. It then flows through the hybrid heat exchanger 34, which supplies heat to the air by means of the heating / cooling circuit or wets it via the dampening water and cools it additionally or with a delay. The combustion air conditioned in this way is purified once again in the two successive filter rows 32, 33 and fed in a suitable manner to the gas turbine.The container 21 of the device 20 is designed such that up to 9 devices 20 can be stacked one above the other both during transport by ship and in storage in the port or at the site of installation. Transport can be effected inexpensively with standardized transport means without additional packaging even after an oversea. The fact that the container 21 is self-supporting and stackable can be achieved either by configuring the container itself in such a way, for which purpose special stiffening elements can also be provided. For example, triangular reinforcing plates are suitable here which are almost rectangular and each have a catheter which extends parallel to the container sides 23, 25 and is connected to a container side. The substantially shorter catheter is connected to the long catheter of the next stiffening element, so that a frame-shaped stiffening results, which can be produced very easily. Alternatively, they can also be right-angled triangles, wherein the catheter sides of two triangles overlap each other. Alternatively, the container 21 can also achieve its rigidity only by the holding devices 39 for the filter elements 38, optionally in cooperation with the filter elements 38, additionally stiffening the latter.For the assembly of the devices 20, the number of necessary crane lifts is reduced from four to two, wherein the devices 20 are self-supporting and therefore do not, as the hybrid coolers hitherto, require a special cross-member for their own lifting.The result is a reduction of the external dimensions of the filter container 21 in depth of about 2.4 m and a reduction of the mass in a 40' container of about 8.2 t to about half in each case compared to a separate solution, as is known hitherto. Moreover, such filter containers 21 can be standardized in this manner. The manufacture can be carried out industrially. Delivery times are shortened. The cost is reduced. The devices 20 are always of identical dimensions and have a uniform, appealing appearance. They can be arranged in different space-saving constellations. If necessary, individual devices 20 can also be replaced quickly by new ones, so that no long downtime arises.In order to further reduce the space requirement in the vertical during transport of the device 20, it can advantageously be provided that a goose corner tunnel (not shown) is arranged in the floor 24 of the container 21. The container 21 rests as a container with the goose corner tunnel on the truck and thus stands lower. The hybrid heat exchanger 34 is then located in the middle on the Gooseneck tunnel, which takes up about 3.15 m of the container length and about 1.05 m of the width and has a height of, for example, 17 cm. Because of the restricted space conditions through the goose corner tunnel, 2 troughs (not shown) can optionally also be arranged in front of and behind the hybrid heat exchanger 34, instead of a trough 36. The sniffer pump 41 is seated in one of the troughs or the transverse connection between them. Both troughs and the support of the cooler in the middle form a watertight unit made of bent thin (stainless steel) sheet metal, which is inserted into the container cross members (made of steel) and is therefore no longer load-bearing and less expensive.Various aspects with regard to the system according to the invention comprising devices 20 according to the invention will now be explained with reference to FIGS. 5 to 10, wherein FIGS. 5 to 9 show purely schematically devices respectively set up in a particular arrangement, namely in a plan view (denoted by "a") and a side view (denoted by "b"). The arrows again illustrate the air flow. In all figures, identical or similar elements are provided with the same or similar reference numerals and their function and their cooperation will not be discussed in detail again.A first preferred embodiment of the system 100 according to the invention is shown purely schematically in FIGS. 5 aand 5 bas an arrangement of three stacks 101, 102, 103, wherein the stacks 101, 102, 103 each comprise three devices 20. These stacks 101, 102, 103 are arranged in the form of a horn around a wall 104 which has a passage opening 105 for the conditioned combustion air to a gas turbine (not shown). In order that the inflow path to the passage opening 105 of all the devices 20 is substantially the same, a suction connection 106 for the combustion air is furthermore provided, one opening 107 of which opens sealingly into the passage opening 105 and the other opening 108 of which is situated approximately in the middle of the space enclosed by the horseshoe, as the circle drawn indicates. In addition, the intake connector 106 is arranged at the level of the central plane of the devices 20, as can be seen from FIG. 5 b. The space between the devices 20 is hermetically bounded in an upward direction by a sheet or the like (not shown) and in a downward direction by the bottom 109. It can be seen, moreover, that the apparatuses 20 are arranged with their reservoirs 29 lying one above the other and in the same direction. With the devices 20 according to the invention, this system 100 has a footprint of approximately 250 m 2 and a lateral perspective extension surface of approximately 116 m 2.The air tightness of the devices 20 with respect to one another can easily be produced, for example, by intermediate positioning of a sealing strip (not shown) during stacking. Such a sealing strip also ensures air tightness towards the bottom 109 and the wall 104 as well as towards the cover plate. The individual devices 20 can be narrowed relative to one another and relative to the environment by means of tensioning straps. Depending on the placement arrangement, only the air duct on the rear side of the devices 20 to the intake connector 106 of the gas turbine is to be individually adapted. The devices 20 are completely preassembled and can be put into operation after a few manipulations for connection to one another. Neither ladders nor service platforms are to be retrofitted on site.A second preferred embodiment of the system 110 according to the invention is shown purely schematically in FIGS. 6 aand 6 bas a first plate-shaped arrangement of three stacks 101, 102, 103, wherein the stacks 101, 102, 103 in turn each comprise three devices 20. In this case, the arrangement encloses a substantially semicircular space, so that the intake connector 106 can close off with the passage opening 105 of the wall 104. With the devices 20 according to the invention, this system 110 has a footprint of approximately 375 m 2 and a lateral perspective extension surface of approximately 107 m 2.A third preferred embodiment of the system 120 according to the invention is shown purely schematically in FIGS. 7 aand 7 bas a second plate-shaped arrangement of three stacks 101, 102, 103, wherein the stacks 101, 102, 103 in turn each comprise three devices 20. In this case, the arrangement also encloses a substantially semicircular space, wherein the middle stack 102 is, however, arranged offset inward. With the devices 20 according to the invention, this system 120 therefore has a footprint of approximately 293 m 2 and a lateral perspective extension surface of approximately 98 m 2.A fourth preferred embodiment of the system 130 according to the invention is shown purely schematically in FIGS. 8 aand 8 bas a wedge-shaped arrangement of two stacks 101', 103', wherein the stacks 101', 103' each comprise four devices 20 in order to approximately compensate for the missing middle stack. In this case, the arrangement also encloses a substantially semicircular space. With the devices 20 according to the invention, this system 130 has a footprint of approximately 214 m 2 and a lateral perspective extension surface of approximately 82 m 2.Finally, a fifth preferred embodiment of the system 140 according to the invention is shown purely schematically in FIGS. 9 aand 9 bas a funnel-shaped arrangement with a stack 102", wherein the stack 102" comprises eight devices 20 in order to almost compensate for the missing lateral stacks. In addition, four funnel surfaces 141, 142 are provided which are formed from a thin sheet of metal with stiffening ribs and extend sealingly from the front opening 108 of the suction connection 106 to the side surfaces of the stack 102", but the antechambers 29 are not enclosed by the funnel 143 which forms. In this case, the arrangement also encloses a substantially semicircular space. With the devices 20 according to the invention, this system 140 has a footprint of approximately 96 m 2 and a lateral perspective extension surface of approximately 164 m 2.With approximately the same flow conditions, these different systems 100, 110, 120, 130, 140 can thus be used to provide installations for the conditioning of combustion air which are particularly adapted to different space conditions at the installation site. Numerous further variants are of course possible here.In an alternative embodiment, in the device 20, instead of one of the filter rows 31, 32, 33, preferably instead of the third filter row 33, a fan wall comprising many smaller individual fans (not shown) could be provided, which are then arranged, for example, in the filter element receptacles 39. The combustion air can be additionally compressed by the fans, so that an increase in pressure also takes place. In this embodiment, filter rows 31, 32, 33 could also be dispensed with in principle, wherein at least the first filter row 31 is preferably retained as a prefilter. The device thus produced can also be used in a targeted manner as a conditioner for the heat transfer medium of the hybrid heat exchanger 34, instead of as a combustion air conditioner. One or preferably several such devices with such fans arranged in a stack to form a system, similar to that shown in FIGS. 5 to 9, would thus be able to form a very effective cooling system or a cooling tower for the heat transfer medium.The systems 100, 110, 120, 130, 140 can furthermore advantageously be provided with air guiding devices 150, 151, which are illustrated purely schematically as in FIG. 10. It can be seen that the devices 20 have air guiding devices 150, 151 arranged downstream in the air flow direction. These air guiding devices 150, 151 are likewise designed as 40' containers and have a frame-like structure with encircling flanges 152, walls 153 being provided only where no air is intended to enter or exit. Openings 154 are formed over the missing walls, via which openings the air guiding devices 150, 151 are connected to one another. The terminating air guiding devices 151 have one or more air outlet openings 155 provided through which the air (indicated by the arrows) is supplied to a gas turbine (not shown). In addition, means (not shown) for smoothing the air flow can be provided in the interior of the air guiding devices 150, 151, so that, for example, no air blockage can result in corner regions. These means can be realized, for example, by bent metal sheets. The air guiding devices 150, 151 are also self-supporting and stackable due to their container container.By means of the encircling flanges 152, which can otherwise also be provided on the devices 20, the air guiding devices 150, 151 can be coupled particularly easily to one another, to the devices 20 and to further devices, such as ducts and weather scoops, it being possible in turn for sealing means to be interposed therebetween. In addition, mufflers can be provided in the air guide in one or more air guiding devices 150, 151, wherein these mufflers can advantageously also be provided directly in or on the apparatus 20.From the above it has become clear that with the present invention devices 20 for industrial media conditioning are provided, the elements of which are optimally combined in a block which can be prefabricated as far as possible industrially and easily adapted to the different application cases and installation locations. Although the invention has been described substantially with reference to the conditioning of combustion air for gas turbines, it is clear that it can be used advantageously for any type of conditioning.List of reference characters20 Device 21 Container 22 Closed side wall (roof) 23 Closed side wall (front side) 24 Closed side wall (floor) 25 Closed side wall (front side) 26 Open side wall 27 Open side wall 28 Flow channel 29 Front chamber 30 Conditioning chamber 31 Filter row 1 32 Filter row 2 33 Filter row 3 34 Hybrid heat exchanger 34 a Vorlauf 34 b Rücklauf 35 Rain deflector with bird protection grid 36 Water collecting trough 37 Grid 38 Filter elements 39 Holding device 40 Ribbed tubes 41 Sniffer pump 42 Secondary feed line 43 Conductivity meter 44 Suspension valve 45 Secondary feed valve 46 Operating handle 47 Floor securing doors 48 Riser conductor 49 Return collector 50 Switchbox 100 System of three devices 101 Stack of three devices 101' Stack of four devices 102 Stack of three devices 102" stack of eight devices 103 stack of three devices 103' stack of four devices 104 wall 105 passage opening 106 intake connection piece for the combustion air of the gas turbine 107 opening 108 front opening 109 base 110 system 120 system 130 system 140 system 141 funnel surface 142 funnel surface 143 funnel 150 air guide 151 air guide 152 flanges 153 walls 154 openings 155 air outlet openings.
