Description

Device for large-scale media conditioning

The present invention relates generally to large scale media conditioning apparatus according to the preamble of claim 1 and a system of a plurality of 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 in so-called filter houses of solid and liquid particles in order to pressurize the working machine with the cleanest possible air. For this purpose, in such an air filter house, mist eliminators, bird screens and usually one or two filter stages are installed. Since the filters as well as the compressors of the gas turbine tend to freeze under given outside air conditions - high relative humidity and temperatures around the freezing point - the air is additionally preheated during this season. For this purpose, heat exchangers, infrared radiators or hot air or rare exhaust manifolds are installed in a filter house, which preheat the intake air indirectly or directly. Such a device 1 is shown purely schematically in Fig. 1, wherein the anti-icing system 2, the weatherproof grille 3, the grid 4, the pre-filter wall 5, the fine filter wall 6, the protective grille 7, the transition piece 8, the Kuhssenschalldämpfer 9 and the supply air duct 10 and the gas turbine 11 are clearly visible. It is essential that filter houses of gas turbines are practically always adapted individually to the particular application and site and made individually or only in small batches. This is associated with a high design effort and long delivery times.

As a result, hardly any optimum regarding flow and pressure loss is achieved. A high flow velocity causes a high pressure loss. Unevenly inflated air filters pollute faster. A small number of air filters also leads to faster pollution and a sharp increase in pressure loss. Em high pressure loss in the filter house causes corresponding performance losses of the gas turbine. Possibly. The polluted filters must be replaced during operation of the gas turbine under unfavorable conditions. A one- or two-stage air filtration leads to an increased dirt entry into the compressor of the gas turbine. This dirt settles on the compressor blades (Fouhng) and also leads to increasing performance and efficiency losses.

Therefore, it is also common to wash the compressor of the gas turbine during operation (online) or in the parked and cooled state (offline). For this purpose, with special washing facilities under high pressure suitable washing solution is introduced into the compressor and rinsed off the baked dirt and rinsed out. In online washes usually needs the power of the gas turbine can be lowered. For offline washes, the gas turbine goes completely out of service for many hours. Both reduce the availability of the gas turbine as the 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 fall. To compensate for this, the intake air is cooled in summer. For this purpose, direct or indirect methods are also used. The direct cooling is possible by the evaporation or injection of water into the intake tract and the associated adiabatic cooling effect. Indirectly, the intake air can be cooled with heat exchangers, which are acted upon by naturally or artificially cooled heat transfer media. To improve the 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 consequences already described. The filter elements are transported when changing under difficult conditions via ladders or winches.

Furthermore, it is known to condition the combustion air for gas turbines hybrid. For this purpose, the combustion air is either heated dry or moistened, or simultaneously heated and humidified with a hybrid cooler (DE 10 2004 050 182 Al). It is also known to combine these process steps in a filter house. Thus, the combustion air of the gas turbine can first coarse filtered in a first filter stage, then conditioned in a hybrid cooler and then finely and finely filtered in two other 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 installation work on the construction site, because the parts can always be moved individually with a crane. Furthermore, connecting flanges or flexible compensators between the individual components are required. Also, the parts are through the tub under the hybrid cooler of different heights, so there are steps in the foundation or the support. To achieve greater air flow rates several modules are required, which are placed individually on the construction site. The hybrid coolers require a special traverse for lifting, which must be delivered separately and removed again. The hybrid coolers must be connected airtight with each other to avoid untreated air bypass flows.

The low air velocity required by the hybrid coolers to prevent gassing results in low pressure loss of the hybrid filter house despite coupling with three-stage air filtration. The result, however, is about twice as large suction surface and about three times as large filter house, as is conventional practice. This is associated with a correspondingly higher weight, which makes conversions to the new method more difficult and requires corresponding substructures. Larger gas turbines would require more than 10 of the listed hybrid coolers. Difficulties arise to unite them in an air filter house. So a maximum of 3 hybrid coolers can be stacked on top of each other, without changing the statics of the radiator housing.

Also known are compact air conditioning units for the air conditioning of air flows in buildings. Again, air is filtered, heated or cooled and humidified or dehumidified, depending on the climate situation and requirements of the supplied premises (for example, DE 44 07 806). However, these devices are not standardized worldwide, not stackable or suitable for larger volumes of air. Gas turbines in turn do not require the complete functionality of air conditioning compact devices.

The object of the invention is therefore to provide a device for large-scale media conditioning, which largely prefabricated industrially and can be easily adapted to different applications and sites. The transport and assembly costs should be kept low. The device should in particular be particularly easily coupled to a system of such devices.

This object is achieved with a device according to claim 1 and a system according to claim 26. Advantageous embodiments are specified in the dependent subclaims.

The inventive apparatus for large-scale conditioning, in particular cleaning, humidification, drying, cooling, heating and / or pressure increase of liquid and / or gaseous media, has at least one conditioning device (eg filters, humidifiers, heat exchangers, dryers, 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 for the storage, transport and / or for the function of the device is self-supporting and stackable. As a result, these devices for large-scale media conditioning can be stored particularly easily, transported and combined into systems, without the need for special preparations, such as trusses during transport or structural engineering precautions during storage. As a result, the disadvantages of known device are eliminated, which consisted of several individual modules and had to be assembled only at the construction site. Now, the device can be prefabricated from standardized segments at the factory, transported to the construction site and there modular assembled and arranged in a very short time as desired.

The devices become standardizable in this way. The production can be industrial. The delivery times are shortened. The costs are reduced. The devices always have identical dimensions and a uniform attractive appearance. They can be arranged in different space-saving constellations. If necessary, individual Devices can also be quickly replaced with new ones, so that no long downtimes arise.

By integrating the individual elements of the device into a single housing, not only can the dimensions of the device be reduced, but also its weight.

It is advantageously conceivable that the container is formed substantially closed at least in a circumferential direction. Then, the container forms a through-flow channel for the medium in one direction, thus providing the medium itself little flow resistance. However, it may alternatively also be provided that the flow channel consciously changes direction, for example, is guided by two adjacent sides of a rectangular container. This can e.g. be advantageous if the installation of the container or the arrangement of many devices to a system of media passage in one direction is not possible.

Particularly preferably, the container is in terms of its length, width and height as a container, in particular according to DIN ISO 668 formed. Such containers have been standard for many years and there is much experience in their transportation, storage and stacking. In particular, these containers are designed for heavy loads, which must necessarily carry such a container in a device for large-scale media conditioning. Suitably, the container with respect to its corner fittings as a container, in particular according to DIN ISO 1161, formed.

It was already known the use of aggregate containers, which take advantage of the container design to accommodate aggregates such as pumps, compressors, combined heat and power plants, water treatment plants, etc. in massive yet mobile housings, factory pre-assemble, to test, in transport a piece to the site and turn off and take very quickly to put into operation, the container thus simultaneously or successively as a packaging, standardized transport container and mobile housing is used. However, these are not devices for large-scale media conditioning and these containers are each no container that forms the housing of the device and a flow channel for the medium, so that a cross-section of the container is flowed through by the medium.

It has now surprisingly been found that the advantages of the container can also be advantageously used for large-scale media conditioning, wherein the stability of the container despite providing a flow channel is still given to the extent that a self-supporting and stackable storage and transport are guaranteed. If one or more stiffening elements are provided in the container for protection against internal and / or external pressure, particularly many devices can be stacked on top of each other and also during transport must be less carefully with the devices um-. to be gone. Preferably, the stiffening elements are formed by one or more angular, in particular triangular, expiring elements, wherein in particular one side of the elements is arranged on each side of the container and the elements of adjacent sides of the container adjoin one another. This makes it particularly simple and inexpensive to achieve a particularly effective stiffening.

Advantageously, at least one heat exchanger is provided. Then the medium can be subjected to heat or heat can be removed. Furthermore, at least one secondary medium transfer device is advantageously provided. Then, for example, the heat of the medium can be delivered to a secondary medium for further use. It is preferably provided that at least one heat exchanger and / or a secondary media transformer, in particular combined are designed as hybrid heat exchanger. At the same time, the secondary media transmitter can simultaneously also assume the function of the heat exchanger by virtue of the secondary medium circulating heat / cold / energy, for which it is circulated through the secondary media transmitter and if necessary supplemented and reheated and / or cooled or regenerated. It can also be provided that the secondary medium is in mass transfer with the main medium (for example, it itself evaporates / vaporizes into the medium to be conditioned or absorbs moisture or dust or the like from the medium to be conditioned). It can further be expediently provided that a secondary media transformer or a hybrid heat exchanger can be operated with a secondary medium, for which a secondary media circuit is formed, wherein preferably in a secondary media circuit one or more secondary media task and / or recording devices, and in particular further at least one secondary media pump and a heat exchanger, a drain and / or a make-up valve are arranged. As a result, the secondary fluid circuit can be maintained particularly easily. Advantageously, a secondary media receiving device is designed as a collecting trough and in particular provided with a walk-in cover, in particular with a grating. Then this element of the secondary fluid circuit can be integrated into the device in a particularly space-saving manner.

Advantageously, it is provided that at least one mixing valve or the like, advantageously a three-way valve is arranged, preferably two, in particular three three-way valves, and / or that for switching between countercurrent and direct current between the secondary medium circuit and air flow of an air conditioning a flow switch in the secondary media circuit and / / or a switch of the air flow is provided. By means of a mixing valve can be switched to internal recuperation for the secondary fluid circuit additionally in operation. By means of two three-way valves, a switchover between DC and countercurrent operation between secondary medium circuit and air flow can be provided. And three three-way valves allow both switching and internal recuperation. Alternatively or in addition to the three-way valves can also be provided pure flow switch. For example, in the secondary media flow through a switchable pump. Or for the air flow through switchable louvers, which change the flow direction of the conditioning. In an advantageous embodiment, it is provided that the conditioning device for internal recuperation has at least one row of tubes which is connected to the wetting medium circuit of the conditioning device and / or has at least one row of tubes which is connected to a bypass in the secondary medium cycle, and / or has a separate Rekuperationskreislauf. In a further preferred embodiment, it is provided that the conditioning device for internal recuperation is connected to the secondary fluid circuit of a heat exchanger whose primary fluid circuit is connected to the wetting medium circuit of the conditioning device.

Particularly preferably, one or more coarse protection devices are provided on the inlet side in the device, in particular for protection against large impurities which, for example, provide protection against driftwood and / or birds and / or also against special weather influences, such as rain, snow or hail.

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 uniform or different filter methods (for example a combination of surface filter and adsorption filter or absorption filter alone etc.) are provided. The filter device is preferably arranged in one of the surrounding walls of the container lying in the direction of flow or walls inside the container which terminate completely in the flow path. The filters of the respective filter devices are expediently arranged one above the other in one or more rows, in particular in four rows.

In a further preferred refinement, one or more devices increasing the pressure of the flowing medium are arranged in the device, in particular in one of the surrounding walls of the container lying in the direction of flow or walls within the container which completely close the flow path. Such devices increasing the pressure of the flowing medium may be, for example, fans, compressors and / or pumps. Instead of a device, a plurality can also be provided, e.g. instead of a big fan several small ones.

Appropriately, a device for preventing icing is also provided. The conditioning devices, in particular the filters of the filter devices, the heat exchangers, the secondary media transmitters and / or the hybrid heat exchangers or anti-icing devices or the pressure-increasing devices are particularly advantageously arranged in respective receptacles, which are in particular designed to additionally stiffen the container. This also improves the conditions of storage and transportation. At the same time, but also the requirement for the container in terms of Stiffness can be reduced. In other words, that the container of the device can either be made self-supporting and stackable out of itself or these properties only in interaction with the other devices of the device for large-scale media conditioning, such as. eg the conditioning device (s). It is essential, therefore, that the container of the present device according to the invention does not have to be self-supporting and stackable by itself.

For maintenance purposes in particular, the container may have at least one laterally arranged antechamber in which no media conditioning takes place, which is connected via at least one sealable breakthrough to a space in which the media conditioning takes place. The closability ensures that media conditioning is not disturbed. This vestibule is then not flowed through by the medium, 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 vestibule on at least one particular closable breakthrough 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 vestibule has at least one riser. As a result, the antechambers of stacked devices can be easily reached. Alternatively or additionally it can be provided that in an anteroom at least one elevator, preferably arranged on a ladder, which is designed in particular to accommodate a plurality of filter elements, in particular according to the number of filter units in the filter means behind or behind each other arranged filter rows. As a result, the devices can be particularly comfortable wait. Instead of the filter elements, of course, other elements of the device and its devices can be easily transported by the elevator.

The apparatus, a heat exchanger, a secondary media supply device or a hybrid heat exchanger and / or an anti-icing device can be acted upon with antifreeze in a particularly expedient manner. For the device as such, this makes sense especially when a liquid medium is passed through the device. Preference is given to devices for measuring the humidity and / or the temperature and / or the pressure and the level or conductivity and / or other quality parameters to be set of the gaseous and / or liquid medium to be conditioned and / or a secondary medium before, on and / or after provided for the individual conditioning stages. In particular, at least one control or regulating and / or monitoring device, in particular for cleaning, humidification, drying, cooling and / or heating or anti-icing and / or increasing the pressure of the gaseous and / or liquid medium or a secondary medium to be conditioned intended. Then the media conditioning can be regulated and monitored very easily. Independent protection is claimed for a system of several devices according to the invention, wherein a plurality of devices are arranged one above the other and / or next to each other, which are preferably sealed to one another at the separation points, wherein in particular two to nine devices are stacked tower-like. By sealing, no already conditioned medium can escape from the system or unconditioned medium can enter the system.

Preferably, the devices are at least mechanically interconnected. Alternatively, it may also be sufficient that the devices are mutually fixed in their position due to their own weight.

Particularly advantageously, a plurality of preferably juxtaposed 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 inlet and / or outlet opening. In that case, it is particularly easy to jointly carry out common media conditioning across all devices.

In an expedient embodiment, the pipelines are hydraulically connected to one another, in particular for the make-up and / or emptying of the secondary media transformers and / or hybrid heat exchangers of the individual devices via collectors. In this way, the leadership of the secondary media can be uniform and thus jointly controllable. Preferably, the flow and return headers in particular the heat exchanger and / or hybrid heat exchanger of the individual devices are preferably hydraulically connected together in the Tichelmann system. In the Tichelmann system, the pipes are routed from the heat generator to the heat consumer and back in the ring installation so that the sum of the lengths of the supply line and the return line is approximately the same for each heat consumer. Heat consumers with short flow have a long return line and vice versa. The point is that all heat consumers are exposed to about the same pressure losses and thus equal volume flows, i. set the same heat flows in the heat consumers, even if no control valves are used. This causes a uniform heating of more distant heat consumers.

Suitably, the control or regulating and / or monitoring devices of the individual devices with electrical current, light or media-conducting cables, preferably with bus systems, in particular electrically, optically or hydraulically connected to each other.

Preferably, devices of a system, in particular one or more, for example tower-like stack-forming devices are connected on the media side via a collector, a funnel and / or a channel at least with a respective upstream and / or downstream device. Alternatively or additionally, one or more devices may also be provided with upstream and / or downstream devices, such as gas turbines, buildings and the like. be connected.

In a particularly preferred embodiment, the device according to the invention and / or the system according to the invention at least one gas turbine, a fan, an air compressor, a building or similar units or devices upstream and / or downstream and the heat transfer media of the heat exchanger, hybrid heat exchanger and / or facilities to prevent icing are energized, especially with (Ab) heat or cold or electrical energy from this unit or this device or its environment act or lead energy, in particular (Ab) heat or - cold from the media stream to be conditioned in this unit or this device or its environment back.

In a further particularly preferred embodiment, the device according to the invention and / or the inventive system at least one gas turbine, a fan, an air compressor, a building or similar units or devices upstream and / or downstream and the secondary media circuits of the secondary media transformer, hybrid heat exchanger and / or Devices for preventing icing or other conditioning devices can be acted upon by substances / media or energy from this unit or this device or its surroundings or lead substances / media or energy from the media stream to be conditioned into this unit or this device or its surroundings , among other things, for its reprocessing.

Independent protection is also claimed for Luftleitemπchtungen, which are preferably used with the inventive device and / or the inventive system. These Luftleiteinπchtungen have a container designed as a container and at least two of the air at least partially through-flow side walls. In addition, inside the container also air baffles or the like. Be provided to avoid turbulence in the corner regions of the container.

Independent protection is claimed for a method for operating the device according to the invention, wherein the secondary medium circuit of Luftkonditioniereinπchtung is at least temporarily operated in cocurrent to the guided through the Luftkonditionieremπchtung air flow.

It is advantageous if, for internal recuperation, already cooled secondary medium is supplied to the secondary medium compartment of the conditioning unit or to the cold secondary medium compartment of the conditioning unit for supplying warm secondary medium from the secondary media inlet to the conditioner device, so that this embodiment is also advantageous in a Counter-current can be used.

In a preferred embodiment, it is provided that the conditioning device for internal recuperation in at least one row of tubes by the conditioning device provides a wetting effect. is guided medium, and / or that in at least one row of pipes the secondary medium cycle via a bypass taken secondary medium is performed, and / or separate secondary medium is guided in a separate Rekuperations- medium circulation, and / or a secondary medium is guided, which is removed from a heat exchanger, whose primary circuit is operated with the wetting medium of the conditioning as the primary medium. This preferred embodiment can also be used advantageously in a countercurrent operation.

It has been shown that it is cheaper to operate hybrid coolers in hybrid cooling mode in DC. This results in a higher relative humidity at the outlet - close to 99% RH, and a lower cooling water outlet temperature, in comparison with a countercurrently flowed through hybrid cooler.

So where an almost saturated air at the outlet does not affect negatively, and the lowest possible cooling water temperature is in the foreground, a hybrid cooler in the hybrid cooling operation in the DC, i. to be flowed through correctly in cross-direct current. However, since it is an advantage of hybrid coolers that they can be operated dry below a certain outside air temperature, which saves significant amounts of cooling water over wet cooling towers, and this with countercurrent, i. is correctly more effective in cross-countercurrent, it may be advantageous to provide a possibility to switch the flow direction on the water side and / or on the air side. However, this can be superfluous if in the transitional period and in winter up to about 3 Kelvin higher cooling water outlet temperatures are required or tolerable.

In particular, in hybrid coolers, in which in addition to the cooling water cooling also the use of moist air takes place, so for example. In the case of hybrid combustion air conditioning on gas turbines, the hybrid DC mode of operation (cross / DC mode) is an option since, in addition to the higher air humidity, lower air outlet temperatures on the hybrid cooler are also achieved on an adiabatic basis. In this case, this results in lower air inlet temperatures at the gas turbine and, as a consequence, higher gas turbine outputs.

Furthermore, it may be advantageous to operate internal recuperation of hybrid coolers regardless of the flow guidance. For this purpose, already cooled cooling water from the cooling water outlet of the hybrid cooler is added to the warm cooling water inlet of the hybrid cooler. The aim is to lower the temperature level in the heat exchanger both on the cooling water as well as on the air side and in the sequence the cooling water as the air outlet temperature compared to a simply flowed through hybrid cooler.

The internal recuperation also works in a hybrid air humidifier that is not used for cooling water cooling. Thus, if cooling water is circulated in direct current (cross / direct current) from the warm air inlet to the cold air outlet in the hybrid cooler bundle, the incoming warm ambient air is convectively pre-cooled. As a result, the temperature level in the heat exchanger sink both on the air as well as on the cooling water and wetting water side and subsequently the air and the cooling water outlet temperature compared to a simply flowed through hybrid radiator humidifier. This increases the performance of the gas turbine in addition to a system with simply adiabatically humidified intake air. If, however, cooling water is circulated in the hybrid cooler bundle in countercurrent (cross / countercurrent) from the cold air outlet to the warm air inlet, the outflowing cold ambient air is reheated convectively. As a result, the temperature level in the heat exchanger rise both on the air side and on the side of the cooling water and, as a consequence, the air and the cooling water outlet temperature with respect to a hybrid radiator humidifier flowed through simply. In particular, however, the relative humidity at the hybrid cooler outlet decreases, which may be a desirable criterion on the side which uses this air, provided that the humidity can not be influenced more easily by other criteria.

Since the pool or wetting water of a hybrid cooler humidifier is always close to the wet bulb temperature and thus even colder than the cooling water in the hybrid cooler bundle, it may be useful to include the wetting water in the internal recuperation. Thus, the wetting water is passed through at least one of the rows of tubes of the hybrid cooler, e.g. to pre-cool the incoming warm ambient air noticeably. As a result, the temperature level in the heat exchanger on both the air and on the cooling water side and consequently the air and the cooling water outlet temperature decrease in comparison with a hybrid radiator with a single flow through it. Subsequently, the wetting water is used for wetting the hybrid cooler bundle from the outside. Due to the adiabatic cooling, the wet bulb temperature in the wetting water is reached very quickly, so that the internal recuperation has a total lowering temperature.

However, since the wetting water on the outside of the hybrid cooler bundle is loaded with air polluting particles, it may be more appropriate to direct the wetting water through wetting water cooling water through an easy to clean heat exchanger and not directly through the hybrid cooler bundle to noticeably pre-cool the incoming warm cooling water , If the external heat exchanger becomes dirty, it can be cleaned more easily than the hybrid cooler.

Furthermore, it can be useful to reserve rows of tubes of the hybrid cooler bundle, in particular on the air-side inlet and / or outlet for internal recuperation with cooling water and / or secondary medium of a separate Rekuperationsmedienkreislaufs, and to realize the hybrid cooling through the remaining intervening rows of tubes , As a result, the recuperation temperature can be decoupled from the cooling water temperature and achieve a higher degree of recuperation.

Since the air cooling can not only be done by a combination of wet and dry cooling, but also exclusively by wet or dry cooling is in the frame This invention also relates to Luftkonditioniereinπchtungen and not only

Hybπdkühler.

In FIGS. 2 to 4, the device 20 according to the invention is shown purely schematically in a preferred embodiment, frontally and in two side views. This device 20 is a large-scale device 20 for conditioning the combustion tion of gas turbines (not shown, similar to FIG. 1). The device 20 comprises a container 21, wherein the container 21 along its length in the circumferential direction with closed side walls 22, 23, 24, 25 is formed. The container 21 is designed as a 40 'container 21, ie it has the essential structural details of such a container and thus also its dimensions (height 2591 mm, width 2438 mm, length 12192 mm). On the other hand, the two side walls 26, 27 along the length of the container 21 are substantially open in such a way that they form a flow channel 28 for the combustion air (arrows indicate in all directions the direction of the flow of the combustion air), whereby the longitudinal cross-section of the Container 21 is essentially traversed by the combustion air. The only part of the cross-section of the container 21, which is not flowed through, is the vestibule 29, which is arranged laterally behind the side wall 25 and opposite the actual conditioning space 30 two tightly closable openings in the form of doors (only schematically indicated with a cross) having. In contrast, for example, to 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 surface advantageously increased and thus the flow resistance and the number of required devices 20 are reduced.

The device 20 further comprises three filter rows 31, 32, 33, and a heat exchanger 34, which is designed as a hybrid heat exchanger 34 and disposed between the first 31 and second filter row 32. Before the first filter row 31, a rain deflector with bird screen 35 is arranged. In the floor 24 of the container 20, a trough 36 is arranged, which is covered with a walk-in grating 37. The filter rows 31, 32, 33 have a multiplicity of filter elements 38 which are arranged in suitable holding devices 39 in the filter rows in the manner of a matrix (in the present case 17 × 4 filter elements 38). By adapting these holding devices 39 and different filter makes can be used or retrofitted as desired at any time.

The hybrid heat exchanger 34 is used for cooling (or preheating), has a flow 34a and a return 34b and is fed with a heat transfer medium (cooling medium in the case of the present cooling) and wetting water as secondary media, wherein the wetting water through the hybrid heat exchanger 34 as in a graduation works, including corresponding water ducts (not shown) are provided. For cooling or preheating, the heat transfer medium is passed through substantially horizontally along the length of the container 21 extending ribbed tubes 40, which communicate with each other hydraulically. These finned tubes 40 are flown by the combustion air flow and extract heat from the combustion air or heat them up. At the same time, the humidified combustion air is humidified via the wetting water and cooled adiabatically in addition or with a time lag. The wetting water is collected in the tub 36 and returned from there by means of a seed pump 41 in a make-up line 42 and redistributed via water distribution channels (not shown) on the hybrid heat exchanger 34. In the make-up line 42, a conductivity meter 43, a Abschlämmventil 44 and a make-up valve 45 are further provided, wherein spent wetting water is drained via the Abschlämmventil 44 and fresh water is replenished via the make-up valve 45 when the conductivity of the wetting water rises above a predetermined value and thus its indicating heavy pollution. The make-up also takes place when the level in the water drip pan 36 has dropped due to evaporation. If there is a risk of frost, the water collecting basin 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) are connected to each other for emptying and feeding the individual devices 20 via collectors (not shown).

Furthermore, the device 20 has a continuous operating step 46 to allow the operator maintenance, and the vestibule 29 has at the height of the first filter row 31 each doors 47 (floor safety doors) in the bottom 24 and in the roof 22, whereby the vestibules 29 one above the other stacked devices 20 are accessible together. In addition, a riser 48 is provided in the vestibule 29, on which also a lift (not shown) can be arranged. The ladders 48 of stacked devices 20 serve the personnel to climb the respective level. By the floor security doors 47 or hatch-like lid in the gratings, the required openings in the roofs 22 and floors 24 of the vestibules 29 are secured against falling. The lift can be designed so that it can be moved over the ladders 48 of stacked devices 20 across. With the lift, a plurality of fresh filter elements 38 can be simultaneously transported up to their destination level upwards, or polluted filter elements 38 can be lowered down at the same time, conveniently and at great speed. From the vestibule 29 lead airtight doors (only schematically indicated with a cross) to the respective filter rows 31, 32, 33 before and after the hybrid heat exchanger 34. The exchange of the filter elements 38 takes place by the soiled elements 38 removed from front to back and then the new elements 38 are reinstalled from back to front. In the disassembled state of the first filter row 31, the hybrid heat exchanger 34 can be cleaned from the front side. In the disassembled 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 wetting water on the rear side, if necessary via the continuous operating step 46.

Finally, in the anteroom 29, a return collector 49 and a flow collector (not shown) with the corresponding inlet and outlet nozzles for the heat transfer medium are arranged. In a plurality of stacked devices 20, the collector 49 all Devices 20 in the flow 34a and in the return 34b connected to each other. On the

Supply connection of the lower device 20, all hybrid heat exchanger 34 for the anti-icing with an antifreeze-containing heat transfer medium is applied. As a heat source for the anti-icing waste heat of the gas turbine, for example, the lubricating oil is preferably used. The return 34b of the upper device 20 is recycled via a separate collector. This allows a uniform loading of all devices 20 in the Tichelmann system (known from the heating technology rule to connect all consumers on supply and return lines with the same length) and a complete ventilation of all elements of the hybrid heat exchanger 34th

The hybrid heat exchanger 34 additionally fulfills the function of a mist eliminator and coalescer. However, these conditioning devices can be retrofitted to further improve the Abscheidefunktion of mist and drops even physically in the direction of passage of the combustion air after the hybrid heat exchanger 34, which in most cases, however, will not be necessary because hybrid heat exchanger 34 verifiably work without swirling.

For the control of wetting functions, the device 20 has a control box 50. Differential pressure gauges (not shown) are installed for measuring the differential pressure of the individual filter rows 31, 32, 33 and possibly also of the hybrid heat exchanger 34. The degree of contamination can be deduced from the differential pressure measured values and measures for exchanging the filter elements 38 can be planned in the event of a sharp increase. To measure the air temperature and the relative humidity before and after the hybrid heat exchanger 34 also corresponding measuring devices (not shown) are also installed. If the air temperature in front of the gas turbine sinks below 5 ^° C., the humidification of the combustion air goes out of operation, above about 7,5 ⁰ C back into operation.

The device 20 now conditions large-scale combustion air for a gas turbine, wherein the air passes through the rain deflector and the bird screen 35 and is cleaned via the first filter row 31. Thereafter, it flows through the hybrid heat exchanger 34 which supplies heat to the air by means of the cooling circuit 37 or moisturizes it via the wetting water and cools it additionally or with a time delay. The thus conditioned combustion air is again cleaned in the two successive filter rows 32, 33 and fed to the gas turbine in a suitable manner.

The container 21 of the device 20 is designed so that up to 9 devices 20 can be stacked on top of one another both during transport by ship and in the warehouse in the port or at the installation site. The transport can be done inexpensively with standard means of transport without additional packaging overseas. That the container 21 is self-supporting and stackable, can be achieved either by the fact that the container itself is so formed, to which even special stiffening elements can be provided. Beispiels- wise here offer triangular stiffening plates, which are almost rectangular and each having a catheter which extends parallel to the container sides 23, 25 and is connected to a container side. The much shorter catheter is connected to the long catheter of the next stiffening element, so that there is a frame-shaped stiffening, which is very easy to produce. Alternatively, they can also be rectangular triangles, the cathets of two triangles overlapping each other. Alternatively, the container 21 can only reach its rigidity by virtue of the fact that the holding devices 39 for the filter elements 38, if appropriate in cooperation with the filter elements 38, additionally stiffen it. For the installation of the devices 20, the number of necessary crane strokes is reduced from four to two, wherein the devices 20 are self-supporting and therefore do not require as the hybrid radiator previously a special crossbar for their own lifting. The result is a reduction in the outer dimensions of the filter container 21 in the depth of about 2.4 m and a reduction in mass in a 4O 'container with about 8.2 t, each about half compared to a separate solution, as it is known so far. In addition, such filter container 21 can be standardized in this way. The production can be industrial. The delivery times are shortened. The costs are reduced. The devices 20 always have identical dimensions and a uniform attractive appearance. They can be arranged in different space-saving constellations. If necessary, individual devices 20 can also be quickly replaced with new ones, so that no long downtimes occur.

In order to further reduce the space requirement in the Vertikalern during transport of the device 20 may be advantageously provided that in the bottom 24 of the container 21, a gooseneck tunnel (not shown) is arranged. The container 21 rests as a container with the gooseneck tunnel on the truck and is thus deeper. The hybrid heat exchanger 34 then stands in the middle on the gooseneck tunnel, which occupies 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. It may also be due to the cramped space through the Goosenecktunnel 2 wells (not shown) are arranged in front of and behind the hybrid heat exchanger 34, instead of a tub 36. The two wells are inserted in front of and behind the gooseneck tunnel in the cross sections and communicate via cross connections. The suffe pump 41 sits in one of the tubs or the cross connection between them. Both troughs and the central cooler support form a watertight unit made of folded thin (stainless steel) metal sheet, which is inserted into the container cross members (made of steel), and thus is no longer load-bearing and cheaper. Various aspects with regard to the system according to the invention of 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 each device arranged in a special arrangement, in a plan view (with "a ") and a side view (labeled" b ").

In an alternative embodiment, instead of one of the rows of filters 31, 32, 33, preferably instead of the third row of filters 33, a fan wall of many smaller individual fans (not shown) could be provided in the device 20, which are then arranged, for example, in the filter element receptacles 39. By the fans, the combustion air can be additionally compressed, so that there is an increase in pressure. In this embodiment, it would also be possible to dispense with filter rows 31, 32, 33 in principle, with preference being given to maintaining at least the first filter row 31 as a prefilter.

In addition, means (not shown) for smoothing the air flow may be provided in the interior of the louvers 150, 151, so that, for example, no cornering can result in air stagnation. These means can be realized for example by curved sheets. The spoilers 150, 151 are also designed to be self-supporting and stackable due to their container container. Due to the circumferential flanges 152, which may also be provided on the devices 20, the louvers 150, 151 are particularly easy to each other, with the devices 20 and with other facilities, such as channels and Wetterhutzen coupled, in turn, sealing means can be interposed , In addition, silencers may be provided in the air duct in one or more air guiding devices 150, 151, wherein these silencers may advantageously also be provided directly in or on the device 20.

FIG. 15 shows the temperature profile when the air conditioning device 220 is operated in direct current according to FIG. 12d. The air of the entering into the hybrid cooler 201 air flow 203 has a temperature of about 33.3 ⁰ C. The secondary medium emerging from the hybrid cooler 201 has a temperature of about 18.4 ° C. When this secondary medium (eg. Cooling water) is fed by means of the three-way valve 221 back to the hybrid radiator 201, then is also input side of the hybrid radiator 201 secondary medium with about 18.4 ⁰ C (cf., lower straight dashed curve in FIG. 15). The refrigerant flowing in the hybrid radiator 201 secondary medium heated initially under the influence of the same air flowing current 203 easily, and then in turn to cool under the influence by adiabatic cooling by means of wetting 206 18.4 ⁰ C (upper dashed arcuate curve in Fig. 15) , Thereby, the temperature of the air flow of 33.3 ⁰ C to about 17.2 ⁰ C are cooled (solid line in Fig. 15). In contrast, when no internal recuperation is made to a process according to FIG. 1 Id is used, the temperature of the air stream 203 can be cooled by the adiabatic cooling in the wetting operation, only to about 18.9 ⁰ C. By means of the internal recuperation, for example, a gas turbine can be supplied with an approximately 1.7 ⁰ K cooler air. Although this air is almost saturated, however, this plays no role, for example, for gas turbines.

FIG. 16 shows the temperature profile when the air conditioning device 220 is operated countercurrently, as shown in FIG. 12c. The air of the entering into the hybrid cooler 201 air flow 203 in turn has a temperature of about 33.3 ⁰ C. The light emerging from the hybrid radiator 201 secondary medium has a temperature of about 20.6 ⁰ C. When this secondary medium (eg. Cooling water) is fed by means of the three-way valve 221 back to the hybrid radiator 201, then is situated at the input side of the hybrid radiator also secondary medium with about 20.6 ⁰ C (cf., upper straight dashed curve in FIG. 16). The refrigerant flowing in the hybrid radiator 201 secondary medium is cooled initially under the influence of counter-current air stream 203 slightly, to then warm up again under the influence of the incoming hot air stream 203 to approximately 20.6 ⁰ C (lower dashed arcuate curve in Fig. 16) , Thereby, the temperature of the air flow of 33.3 ⁰ C to about 19.4 ⁰ C are cooled (solid line in Fig. 16). In contrast, when no internal recuperation is made to a process according to FIG. 1 Id is used, the temperature of the air stream 203 can be cooled by the adiabatic cooling in the wetting operation to about 18.9 ⁰ C. By means of the internal recuperation the temperature of the air flow 203 is warmer by about 0.5 ⁰ K, but also dryer. This air 203 may be advantageous for air conditioning and the like. Be used when high humidity and thus possible steam formation are undesirable.

As the medium of all circuits 204, 205, 206, 209, preference is given to using water that is optionally provided with auxiliary agents, such as antifreeze, anticorrosion agents and the like. It can be seen that the air conditioning device 200, 220, 240, 260 according to the invention can be operated in a wide variety of ways, whereby it is optimally adaptable to given requirements.

Also, it should not go unmentioned that the transport of the secondary medium 222; 262 can also take place by means of other means already known, for example, in particular with regulated jet pumps or separate, in particular, regulated mixing pumps (both not shown separately). Also, instead of hybrid coolers, for example, otherwise wetted heat exchanger, and finned tube heat exchangers can be used before, in or after which, for example, with nozzles or perforated / porous hoses or surfaces wetting medium is applied.

From the foregoing, it has become clear that the present invention provides apparatuses 20 for large-scale media conditioning and methods for their operation, the elements of which are optimally combined in one block, prefabricated largely industrially and easily adapted to the various applications and sites can be adjusted. Although the invention has been described essentially 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, ie also for secondary-medium cooling alone.
