Definitions
- the invention relates to an air filter system, in particular for gas turbines, which has a nominal air throughput of at least 90,000 m 3 / h, with a filter house which is arranged on a frame which is provided for receiving or deriving the static and dynamic forces acting on the filter house and with an air duct through which the filter house is connected to an air consumer.
- Air consumers with a comparatively large air requirement are mainly required in industry or in commercial operations.
- Gas turbines are an example of this, and they are often used in industry or in power plants to generate electricity or to directly drive machines or components such as compressors and pumps.
- Gas turbines are generally standardized products that are hardly adapted to the special conditions of their use. For example, the same type of gas turbine is used in a location with comparatively high ambient temperatures with dry dusty air, such as a desert, as well as in locations with comparatively low ambient temperatures and humid air, such as in Northern Europe.
- the various environmental conditions influence the performance of the gas turbine in such a way that usually its auxiliary systems, such as the cooling system for lubricating oil and the air filter system, the respective conditions of the location
- BEST ⁇ TSGU ⁇ GSKOPIE have to be adapted in order to obtain a gas turbine system as a whole, the components of which are technically matched to one another and thus produce an optimized system.
- Air filter systems that have become known for such applications are also optimized on the basis of a large number of parameters which are to be determined specifically for the location or which are specified accordingly, such as, for example, the amount of air required by the gas turbine, the air humidity, the dust or particle loading of the air and the maximum permissible Pressure drop across the filter system.
- the result of the optimization is usually a filter system planned individually for the location in question.
- the disadvantage here is that the individual planning results in an individual design result with comparatively high planning costs, with many necessary planning steps that open up the possibility of errors and with project-specific manufacturing specifications, in particular in terms of materials and quantities.
- the filter systems generally have such large dimensions that assembly must take place on the construction site.
- the degree of prefabrication is accordingly low, which has an adverse effect on the quality of the final assembled filter system and also increases the assembly time.
- an air filter system is characterized in that the supporting structure of the filter house is formed by at least one frame module, which is standardized in its dimensions, and in that a force-absorbing supporting structure of the at least one frame module for the static occurring and dynamic forces of a predefinable load case designed for a predeterminable filter house.
- a filter house can first be specified. This is expediently a filter house in which a combination of frame modules is specified, the frame modules are comparatively highly loaded, and which is also exposed to certain maximum loads on wind and weather forces, such as humidity and temperature, or earthquakes.
- the frame module selects, for example, the frame module that has to endure the highest stress in the given filter house, that is to say the greatest forces occurring in the given case, for example due to weight or wind load.
- the supporting structure of the frame module is designed for this case of the specified filter house and the specified load case.
- the outer dimensions of the at least one frame module are standardized, that is, they are uniformly defined for all applications of the frame module.
- the frame module according to the invention can only be adapted to the filter system to be built in a particularly simple manner by combining the required number of frame modules and their corresponding arrangement and configuration. Due to the universal design, especially for an extreme load case for the frame module, the individual design is avoided individually for each filter system. If, for example, a comparatively large air flow to be filtered is required, the structure of the filter house is formed by a correspondingly larger number of frame modules than is the case with a smaller air flow to be filtered.
- the dimensions of the frame module are standardized. This makes it possible, for example, to prefabricate the necessary technical equipment for the frame modules, for example holding frames for prefilters, without having to wait for the otherwise customary design of the dimensions of the supporting structure of a filter system.
- the frame module can be used in a particularly flexible manner and can be adapted to the requirements in a particularly simple manner.
- the at least one frame module is cubic or cuboid.
- a structurally particularly advantageous shape is achieved.
- particularly favorable arrangements or configurations of the filter house can be realized with the cube shape. A particularly flexible use of the air filter system is made possible.
- the cuboid shape of the frame modules it is advantageous that a larger construction volume can be achieved with each frame element than is possible in comparison with the corresponding cube shape.
- elongated bodies can be transported using the same means of transport, such as trains or articulated lorries, as the cubic ones.
- two dimensions of an object to be transported are particularly limited by the means of transport; in the case of truck or rail transport, for example, these are a maximum transport width and a maximum transport height.
- the maximum edge length would be specified, while with the cuboid shape, especially when choosing a square end face, the length can be varied.
- the at least one frame module is formed by frame elements made of longitudinal profiles, in particular standardized steel profile rails.
- Such profiles are usually available from stock and are also available internationally. This advantageously shortens the procurement times for the materials.
- a comparatively simple implementation of the design is achieved with standardized components.
- a first side surface of a frame module are adapted to the corresponding clear dimensions of a second side surface of a standardized freight container.
- An introduction of the concerned Frame module through the second side surface in the freight container is easily possible.
- Standardized freight containers are of major importance in transport logistics and can be transported in a particularly simple manner by truck, train or ship, because these means of transport are optimized for the transport of the freight containers.
- the dimensions of a frame module are optimized in the case given to the transport dimensions of the freight container. In this way, a frame module can be packaged seaworthily on a particularly simple field, which saves an otherwise required separate, requirement-based, complex individual packaging.
- a logistics network developed worldwide is available for freight containers, which enables comparatively fast transport.
- Another possible embodiment of the air filter system according to the invention provides that reinforcement beams are arranged on a frame module, each of which connects two adjacent, parallel frame elements to one another. This configuration advantageously increases the stability of the frame module.
- the frame module is therefore relatively highly resilient.
- a further development of the subject matter of the invention provides that the reinforcement beams are arranged at certain intervals and at right angles to the frame elements connected by the reinforcement beams.
- a subdivision of the frame module into partial areas is made possible, particularly in the case of rectangular frame modules, in which each of the partial areas can be easily equipped with a technical function, for example two of three existing areas can be provided with walls and the third area with an implosion door as a protective measure against negative pressure on a clean air side, which is the side of the filter system on which the already filtered air is located.
- a further improvement of the subject matter of the invention is achieved if the arrangement of the frame elements and / or the reinforcement carriers of the at least one frame module is standardized.
- Only a basic construction diagram of a module type is necessary, regardless of the function for which the module is to be used in detail. In this way, the production of the frame modules can already be started at a comparatively early stage in the project, when only the number of modules is roughly fixed. At a later point in the project, when the detailed planning has determined the design of each individual frame module, the frame modules are completed according to a degree of production at which transportation is still possible.
- a frame module can be connected to a further frame module on each side surface.
- the frame module can be used particularly flexibly.
- such dimensions are selected for the frame elements on each side surface that a connection to a possible adjacent frame module is made possible by rows in the frame elements with recesses, for example drill holes or elongated holes, being provided in a specific, fixed arrangement.
- the adjacent frame module to be connected also has an arrangement of recesses which are matched to the arrangement of the adjacent frame module in such a way that the frame modules in question can be easily assembled with a screw connection, avoiding an otherwise customary adaptation of the recesses during assembly on site is.
- At least one holding frame is formed by the frame elements and possibly by the reinforcing beam or reinforcements on one side surface, to which a mounting frame for filter elements or other functional elements can be mounted.
- Essential functional elements in addition to the pre-filter, intermediate filter or fine filter elements can in particular be wall elements, door elements, implosion protection elements or weather hoods or a combination of these elements. However, it is also conceivable that these elements can be at least partially mounted directly on the holding frame or frames without a mounting frame.
- the mounting frame can, for example, be weldable, screwable, clampable, clipable or adhesive to the at least one holding frame.
- An advantageous further development of the subject matter of the invention provides that electrical and / or measurement connecting lines are preassembled on the at least one frame module.
- This configuration also increases the degree of prefabrication of the frame module.
- the assembly work on the construction site is favorably shortened.
- the possibility of errors is reduced by a comparatively small number of assembly steps during construction site assembly.
- a further advantage results if the preassembled connecting lines of a first frame module can be detachably, in particular plugged, locked or screwed, connected to the connecting lines of a second frame module assigned to them or to master lines.
- the assembly speed can be increased.
- the technical requirements for the assembly staff decrease.
- the electrical connection elements provided for the detachable connection can also be clearly coupled, for example by differently form-fitting configurations of the individual electrical connection element pairs.
- the air filter system according to the invention relates to the air duct, which is formed from at least one frame module.
- the air duct required for supplying the filtered air from the filter house to the air consumer can also advantageously be formed with frame modules.
- the individual frame modules are usually already prefabricated and can be assembled particularly quickly and securely in this way. Further advantageous configurations can be found in the independent claims.

- a fifth 40 and a sixth support element 42 of the first frame module 10 connect the fourth support element 18 to a seventh support element 44 which, like the fourth support element 18, is formed from three support profiles 44a, 44b and 44c and can be assigned to a rear side.
- assembly rods 54 are shown as a further exemplary embodiment, of which only two are provided with reference numerals by way of example and are arranged on the inside of the first frame module 10 facing side of the rear side.
- the mounting rods 54 run vertically downwards from the top and are arranged at such a distance from one another that standardized filter elements, which in this example consist of four individual pocket filters joined together, rest on two adjacent mounting rods 54 and can be held or mounted.
- first frame module 10 can be mounted in a particularly simple manner, for example with screw connections on a steel frame or on a further frame module.
- the four reinforcement profiles 20, 22, 24, 26, which were visible in the front view are designed as U-profile rails.
- the U-profile rail is a standardized steel profile with the advantage of constant availability in stock. This advantageously shortens delivery times.

- FIG. 3 shows a further side view of an end face of the first frame module 10, in which a so-called standard-sized worker 61, shown in broken lines, is drawn in to illustrate the size relationships of this exemplary embodiment.
- the lower fifth support element 40 is connected at its ends to an eighth 60 on the rear side and to a ninth support element 62 on the front side, which in turn are connected to a tenth support element 64 at their other, upper end.
- the support elements 40, 60, 62, 64 mentioned form an essentially square end face of the first frame module 10.
- the bores 58 are again shown, with which the first frame module 10 can be connected, for example by means of rivets, to a frame located on the end face or to an adjacent further frame module.
- a second support grid 66 is shown in section, which is arranged on the side of the rear facing the inside of the first frame module 10 and is connected to it.
- Three filter modules 68 which are shown as a dash-dotted line, are intended to show the possibility of how such filter modules 68 can be attached to the second support grid 66 in a particularly simple manner.
- the first frame module 10 is designed for a case in which the ambient air enters the module from the front.
- the ambient air can already be cleaned of coarse impurities or dusts, for example by a first filter stage, the so-called pre-filtering.
- the pre-filtered air arrives at the rear and through the second filter stage, the so-called fine filtering, which, as required, filters out the disturbing particles still in the air flow.
- FIG. 4 shows a second frame module 70, which is attached to a hitch 72 of a lifting device, not shown, for transport purposes.
- the two te frame module 70 is formed only from support elements which are provided with reinforcing profiles, so that a structure which is in principle comparable with the first frame module 10 can be seen.
- an extension of the second frame module 70 which is intended on the end face, shows a standard freight container 74 (not drawn to scale), the end loading doors 76 of which are open.
- a roller 78 is arranged between the second frame module 70 and the freight container 74 and is mounted on a bearing block 80 standing on the floor. The second frame module 70 is placed on the roller 78 in the vicinity of the end facing the freight container 74 and is easily brought into the freight container in a second step.
- the outer dimensions of the second frame module 70 are matched to the inner dimensions, that is to say the inside dimensions of the freight container 74, so that transport in them is readily possible.
- Freight containers are also suitable for sea transportation. A separate seaworthy packaging of the frame modules can thus be dispensed with.
- Freight containers are also available in various lengths. For example, it is provided that three frame modules of a standardized length of, for example, 5830 mm, that is to say face to face, are placed in an 80 inch freight container.
- FIG. 5 shows a view of the end face of a first exemplary arrangement 82 of six interconnected frame modules 84 to 94.
- Such an arrangement is usually achieved after assembly on a construction site, in which the first arrangement 82 is fastened to a steel frame, which is shown here but was not shown.

- the neighboring modules arranged one above the other have the same technical function.
- the frame modules 84 and 90 are arranged one above the other on the left side of the first arrangement 82 in this view.
- a rain protection hood 96 is attached to each of the outer sides, which ensures an inflow of the ambient air, which mainly takes place from the direction of the floor. The penetration of rain is essentially avoided.
- An anti-icing system 98 is arranged in the air path on the open and air-flowed underside of each rain hood, which, if necessary, in particular in certain weather conditions, heats the air flowing through, so that ice formation in the air filter system, in particular on the air filters and the filter modules, is avoided ,
- pulse filter modules 100 are arranged in the respective left-hand sides as first pre-filters. Furthermore, in each of the left frame modules 84, 90, doors 102 are arranged on the visible end face, in order, for example, to gain access to the interior of the frame modules for changing the filter elements. In addition, a prefilter module 106 is attached to the right side of the frame modules.
- the first arrangement 82 is essentially mirror-symmetrical to an imaginary axis of symmetry 104. Accordingly, the described functional elements, such as, for example, rain covers 96, anti-icing system 98 and pulse filter 100, can also be found mirror-symmetrically on the frame modules 88, 94 arranged on the right in this view.
- the two frame modules 86, 92 arranged between the already described frame modules 84, 88, 90, 94 are equipped on their left and right sides with fine filter modules 108.
- An implosion door is attached to each of the end faces shown.
- the air flow to be filtered is conducted from the surroundings via the anti-icing system 98 into the rain covers 96.
- the air flow is brought from these to the pulse filters 100, which carry out a first pre-filtering.
- the air flow passes through the side ones Frame modules 84, 88, 90, 94 to the pre-filter modules 106 and via these to the fine filter modules 108 into a clean room area which is essentially formed by the two middle frame modules 86, 92 arranged between the side frame modules 84, 88, 90, 94.
- the filtered air is located in this clean room area and is guided from an air duct (not shown in this figure) to an air consumer, for example a gas turbine.
- FIG. 6 shows a sketch of a partial area of a gas turbine power plant in an isometric view obliquely from above.
- Two air filter systems according to the invention can be seen, each having a second arrangement 110, each with six frame modules 112, via which the required air is sucked in.
- the second arrangements are each connected to a support structure 114 made of steel, which support the arrangements at a certain height above the ground level of the gas turbine power plant.
- an air duct 116 is connected, which begins at an end face of the corresponding frame module 112 and first conducts the filtered air through a straight duct piece, which is followed by a 90 ° elbow to be again in one straight duct section to feed the filtered air to an air inlet area of a gas turbine, which is arranged in a building 118 together with the gas turbines, not shown here.
