Description

Wind energy plant with C0 ₂ collector and wind energy C0 ₂ collector

Control or operating procedure

The invention relates generally to the field of renewable energy production by means of onshore as well as offshore wind turbines, and additionally to the field of C0 ₂ outdoor air filtration and CO ₂ collection, namely the field of environmental engineering.

In particular, the invention relates to a power plant with C0 ₂ collector with a tower on a foundation or a base platform, a nacelle and

Power plant rotor blades, comprising a non-blown outside air intake device for sucking the outside air into the energy installation, arranged in and / or on

Machine house and / or in and / or on the tower and / or in and / or on

Foundation area, as well as an outside air-air duct for guiding the sucked outside air through the power plant or at least through portions of the wind turbine to the wind turbine rotor blades, wherein in the wind turbine rotor blades

Air outlets are provided for blowing out the sucked and guided outside air, and a carbon dioxide deposition and / or recovery / collection / C0 ₂ - collector for carbon dioxide capture and / or recovery from the outside air.

Further, the invention relates to a Wndenergieanlagen-C0 ₂ -collector control method with a Wndenergieanlage with C0 ₂ collectors.

In the embodiments of the prior art can first be a first state of

Determine technology from which different wind turbines are known, which can be both onshore and offshore wind turbines and produce electricity by converting wind energy.

Here are the offshore wind turbines, mostly on anchored in or on the seabed base platforms, basically in the sea, as there significantly higher wind yields are possible. Nevertheless, the location of the offshore wind turbines also causes location-related disadvantages, namely in particular the high humidity and the high salt content in the air. Both factors have a negative effect on the materials of the plant as well as on the system components of the offshore wind turbines. The situation is similar for Onshore family wind turbines, which are also exposed to high humidity, but are on land and are usually based on foundations. The rotor blades, which mainly consist of glass fiber and / or carbon fiber reinforced plastic, can be damaged by the high humidity and the high salt content of offshore installations, or weakened or even destroyed over the course of more than 20 years. In this case, it has been recognized in particular on this side that not only the outer area of the offshore wind turbines is relevant, but also the interior, namely in particular the rotor blades of

Wind turbines.

In addition to the rotor blades of the wind turbines, the following components also belong to the site conditioner system components, namely a central hub, at which the two or three, currently there are essentially three,

Power plant rotor blades are combined to form a central association, a nacelle, which is also referred to as a nacelle, in which the mechanical driveline, namely the machine train, which includes the rotating parts such as hub, rotor shaft, possibly gear and corresponding bearings and seals are arranged , and further includes the generator arranged thereon.

Also, other components are just as critical to the system and of the

Site conditions of the wind turbines highly vulnerable, which include the pitch adjustment, possibly provided brakes and electronic control systems and the like. The components are not only provided in the machine house, but also in the area of the hub, for example, for adjusting the angle of attack of the rotor blades.

Furthermore, there is the possibility of designing alternative powertrain concepts, wherein, for example via fluid power drives and controls, the power from the hub is transmitted to a generator provided in the nacelle, in the tower or in a special attachment to the energy plant. In this case, on the one hand, the generator or its space must be appropriately ventilated and, on the other hand, the other system components must be protected in order to avoid damage from the site-related environmental conditions.

In the prior art, it is more or less due to the aggressive, often saline

Sea air, which causes the power plants are highly susceptible to corrosion, has become almost standard that, inter alia, the use of seawater-resistant materials, the improvement of corrosion protection, the complete encapsulation of certain assemblies and the use of equipped with fresh air aspirator nacelles and towers. It has been recognized in particular on this side that in the offshore wind energy plants in the prior art, a large potential for improving the offshore Wndenergieanlagen efficiency or an increase in efficiency is feasible, while an increase in the lifetime of the entire system could be possible because of special attention on the part of the inventor on the unused in the prior art air, was placed from the engine house of the offshore wind turbines.

For this purpose, from EP 2 466 128 A1, EP 2 639 450 A1

Air conditioning systems and powerhouse ventilation systems for power plants are known in which the engine house is vented with externally supplied and filtered air, the air is sucked into the machine house and elsewhere the

 Leaves the machine house again, with the air in the engine house is conditioned accordingly.

 Furthermore, from the document EP 2 320 076 A2 as well as the publications WO 2004/036038 A1, US 2010/0143122 A1 and JP 2005-69082 A a corresponding system on a

Wndenergieanlage known in which air is passed through sections of the machine house through the hub in the rotor blades and can be optionally discharged at several points, in which case energy / heat can be passed from the machine house in the rotor blades, for example, to Eisfreihaltung the rotor blades.

Furthermore, in the prior art embodiments, a second prior art may be determined, from which different arrangements are known to wash out or filter and / or collect carbon dioxide, in short C0 _2, from the air, and then subsequently process it or to store or process.

WO this regard, from the documents WO 2015/185434 A1, 2014/170184 A1, and 2016/005226 A1 corresponding devices and embodiments further known from WO to wash C0 ₂ from the air or C0 ₂ from the air by means of

Bind Adsorbtionsprozessen and this then dissolve out and collect. Such C0 ₂ filter systems always require a high air flow, which is realized in the prior art by appropriately sized fans, but these require electricity again. Furthermore, according to the C0 ₂ separation still from the publication WO 2015/036603 A1 a C0 ₂ gas scrubbing is known, which only shows an alternative Augestaltungsform the type of adsorption.

 With regard to further processing, reference is made to EP 2 049 232 B1

by way of example, from which a method for Nederaufarbeitung of

Combustion products of fossil fuels, so C0 ₂ , is known, in which case C0 ₂ and H ₂ 0 to synthetically produced methane / gaseous and / or liquid hydrocarbons in a methane or Fischer-Tropsch synthesis or other suitable

Hydrocarbon synthesis is further processed. Furthermore, reference should also be made to the publication WO 2016/161998 A1, in which the technology of C0 ₂ extraction and the production of synthetically produced methane are combined, but based on large-scale production plants.

The related problem of the prior art can be represented essentially such that these at least two technologies, namely CO ₂ scrubbing / collection and power generation by means of wind turbines are considered separately from each other.

Only it is stated again and again that the electricity generated by means of renewable energy from renewable energy sources for the production of synthesis gas or hydrocarbons is used. An actual plant-appropriate combination with synergetic effects is not provided. The problem of the inefficiency of the C0 ₂ washing devices, especially the stand-alone systems for filtering the C0 ₂ from the ambient air, is immense, since a high energy expenditure for the air supply to the C0 ₂ collector is necessary, which in turn

Substantially from renewable energy sources is to be obtained, so that this energy is missing in total the actual consumer further, since the renewable energy produced, for example, with a Wndenergieanlage, directly to C0 ₂ scrubbing the ambient air is used.

Of course, a possible consequence and possible solution that has not yet been implemented, a C0 ₂ collector of the prior art would be easy on the

To set the machine house of a Wndenergieanlage and operate this so that the Wnd quasi the supply of the air itself takes over, so that no additional fans are necessary to bring the air in the C0 ₂ collector, since advantageously

In particular, an energy system always aligns in the direction of the wall in order to achieve the highest possible level of control, so that the inflowing wall is directly sufficient. However, this obvious consequence also has disadvantages, since the efficiency of the C0 ₂ collector would fluctuate considerably, since the wind does not blow uniformly, which would lead to naturally feasible solutions, namely corresponding electronic controls and air deflections, such as by-pass controls or the like. so as to get around the problems. At the same time, however, the maximum would not be achieved from such a combination. Rather, this page investigations have shown that such simple combinations lead to problems because the necessary uniform flow of the C0 ₂ filter is not guaranteed and it lacks in efficiency. On the basis of these considerations, the following object is to be based on this side of the present invention, namely to show a wind energy plant with additional function at least the collection or washing C0 ₂ synergistically connects at least the two technologies together to increase the overall efficiency, a in the Maintaining substantially continuous and harmonized operation, in particular of C0 ₂ collectors, while at the same time producing clean electricity from renewable energy sources while at the same time filtering and at least collecting C0 ₂ from the air. In particular, the pre-equipment of C0 ₂ filter assembly with fans or fans should be excluded, since they require energy that would be missing the entire electrical network.

This problem is solved with a wind energy plant with C0 ₂ collector according to

Main claim and further with a wind turbine C0 ₂ collector control method according to the independent claim.

According to the invention, the energy installation has an essential feature of a C0 ₂ collector. Furthermore, in general, the energy system is formed: with a tower on one

Foundation or a basic platform, a nacelle and wind turbine rotor blades, and further includes in particular:

 a non-blown outside air intake device for drawing outside air into the outside air intake device

 Energy installation, arranged

 - in and / or at the machine house and / or

 - in and / or on the tower and / or

 - in and / or at the foundation area;

 - An outside air-air duct for guiding the sucked outside air through the

 Wndenergieanlage or at least through parts of the Wndenergieanlage into the Wndenergieanlagenrotorblättern, wherein in the wind turbine rotor blades air outlets for blowing out the sucked and guided outside air are provided

and

a carbon dioxide separation and / or recovery / collection device / C0 ₂ collector for carbon dioxide capture and / or recovery from outside air with fanless air supply

 - on and / or in the foundation area

 and or

 - at and / or in the tower

 and or

- on and / or in the machine house, the wind turbine being further characterized by the fact that the sucked and guided outside air is passed through the carbon dioxide capture and / or recovery /

Collection device / C0 ₂ collector is guided by an air guide and from the

Air outlets of the rotor blades is led out, one by rotation of the

Wind turbine rotor blades caused by suction effect when blowing an air flow, which causes the air flow of the outside air.

Overall, this results in a synergetic combination of these at least two different technologies, by the combination of clean electricity is produced on the one hand and on the other hand C0 ₂ washed from the air or filtered or collected.

In case of plant standstill, it is possible to continue to operate the C0 ₂ collectors via an additional fan which is not required for main operation.

 The synergy of this combination is to be seen in particular in the fact that the suction effects of the rotating rotor blades when blowing out the sucked air creates an immense flow of air that actually remains unused in the future, but in this case by the

Arrangement of C0 ₂ filter assembly / carbon dioxide capture and / or recovery / collection device / C0 ₂ collector just makes the energy-consuming fan assembly of the previously known C0 ₂ collector unnecessary and at the same time provides even higher air flow for the C0 ₂ laundry. The savings in energy consumption of the C0 ₂ collectors, which conventionally have to be operated with blowers to allow such a sufficient air flow through the filters, are enormous by this combination, since the blowers can be completely dispensed with.

 Both devices and correspondingly configured methods in combination therefore save energy or make sensible use of the available energy for further purposes.

Furthermore, the carbon dioxide capture and / or recovery / collection device / C0 ₂ collector is used as adsorption collector with regeneration phases and / or as

recirculated adsorption collector advantageously designed so that depending on

Design quasi on the one hand in batch mode, first collecting and then carried out by regeneration, for example by temperature addition, a discharge of the collected C0 ₂ , so that further after the regeneration C0 ₂ can be collected, or in design as a circulated adsorber material, eg Liquid, can be collected continuously C0 ₂ and discharged from the process and further processed. In particular, a regeneration of C0 ₂ collectors can be made in the times in which the wind energy generated wind can not be delivered through the network to consumers, since there is no need, so that at these moments this excess electrical energy can be used to the C0 ₂ collectors to regenerate, since it is also economically free energy, which also offers synergistic advantages, since the wind turbines are now allowed to operate permanently and can.

With regard to the Weiterprozessierens can be at the C0 ₂ removal of

Carbon dioxide deposition and / or recovery / collection device / C0 ₂ - collector provide a storage arrangement and / or a Nuhaufarbeitungsvorrichtung of CO ₂ , wherein in this case CO ₂ and H ₂ 0 to synthetically produced methane / gaseous and / or liquid hydrocarbons in a Methane or Fischer-Tropsch synthesis or other suitable hydrocarbon synthesis are processable, which ultimately artificially produced liquid and / or gaseous fuels and these can be removed via existing transport routes, such as the natural gas network or corresponding pipelines or tanker trucks.

When combining the C0 ₂ collector with a suitably designed

Hydrocarbon synthesis can also remove any waste heat for the regeneration of the

Adsorber material can be used.

 In addition, surplus regeneratively generated electrical energy of the energy plant can be used in times to operate the synthesis processes of the hydrocarbon synthesis or any associated water electrolysis.

 Considered further, such a configuration with a synthesis processor for hydrocarbon production arranged in a Wndpark can be used reasonably and efficiently, so that decentralized fuel production possibilities are given, since these are

Synthesis processors can just be operated with regenerative energy, which can be provided just by the power plants.

 Furthermore, it is particularly advantageous if within the outside air-air duct

Filter device for filtering the sucked outside air is provided, wherein at least dehumidification and / or desalination and / or dust / particulate matter filtering is feasible, so that the air moisture content of the air is reduced and thus the air when forwarding to the other parts of the system and in particular the Rotor blades could not harm any system components due to excessive humidity.

In the design of the arrangement of the C0 ₂ collector or carbon dioxide deposition and / or -gewinnungs- / -Sammelvorrichtung these can within and also be placed outside the wind turbine. In the simplest embodiment, these C0 ₂ collector could be built on the machine house or around the tower or be provided at the foot of the tower in the foundation area, which makes sense a multiple arrangement makes sense, since so many individual C0 ₂ collector can be provided which can not be individually regenerated at least at the same time, so that individual collectors are currently being regenerated while other collectors are still in the

Collective work.

 In this regard, the carbon dioxide capture and / or recovery /

Collection device / the C0 ₂ collectors are arranged horizontally or vertically. In this case, a vertically arranged column could be mounted in particular within the tower, so that a long Adsorberstrecke is realized. In particular, this could be done with a liquid that at different height sections in this

Reaction distance is introduced and so dripped by gravity due to adsorption down or flows or rather is passed. Overall, therefore, offers the interior of a tower of a Wndenergieanlage, as well as this structure withstand corresponding loads on the part of the weight.

 An arrangement in the nacelle or in particular in the tower of the power plant is also particularly useful because the collectors are arranged weatherproof in this way. This also offers a multiple arrangement over the entire tower height, which makes sense the air flow through appropriate air ducts or the like.

is performed accordingly. In the air duct, a correspondingly large pipe cross-section must be taken into account, so that the flow is minimized.

 In the arrangement within the tower, quite a few individual collectors can become one

superposed collector unit, whereby the normally empty and useless tower gets a function, namely the inclusion of C0 ₂ collectors and their protection against the effects of weathering, so that the adsorption of C0 ₂ can take place regardless of the weather conditions.

For this purpose, in particular, the air duct may be arranged at least in partial areas of the machine house and / or the tower and / or the foundation area, so that depending on the configuration or arrangement of the C0 ₂ collector a corresponding air supply is ensured.

The air duct is largely realized via pipes, for example via plastic pipes. In individual sections, as well as, for example, when flowing through the machine house or the rotor blades, the air flow, for example, can be guided or directed by air guide elements or flow but also completely free.

Overall, the C0 ₂ for use in the production of synthetic fuels or for fertilization, fertilizers for agriculture and food production, or the like., As mineral water production, packaging of meat products (preservation), production of dry ice or plastic production.

To the operation of a C0 ₂ collector is exemplified that ambient air is filtered and this is the C0 _{2 is} removed. The filters are saturated with C0 ₂ via an adsorption-desorption process, which is a catalytic process. For desorption, heat (about 100 ° C) is required, which can be generated electrically as well as by supplying water. The C0 _{2 is dissolved in} gaseous form from the filter and transported away and collected or further processed.

In addition, an optimized aerodynamics for the turbine engine intakes of the C0 ₂ - collectors can be realized by the arbitrarily selectable arrangement of C0 ₂ collectors in and / or on the Wndenergieanlage.

 In addition, an automatic alignment of the turbines by the azimuth control of the wind turbines can take place.

Second, the desorption of C0 ₂ can be done by generator waste heat with the assistance of a heat pump.

Due to the large-scale distribution of the wind turbines in a wind farm, a central C0 ₂ collection point is particularly useful, which is fed via a piping system.

The energy systems - C0 ₂ collector - control or operating method with a Wndenergieanlage invention with C0 ₂ collector has the essential steps:

Generating electrical energy through the intended operation of the

 Wndenergieanlage;

 - Generating an air flow parallel by the blowing of air to the rotating rotor blades, wherein the suction creates a suction, the other outside air fan / gebläselos by the outside air intake device via the air flow through the

Carbon dioxide separation and / or recovery / collection device / the C0 ₂ - collector supplies

and

- collecting C0 ₂ from the supplied outside air.

As a result, in a minimalistic embodiment, a method is specified, which synergistically collects C0 ₂ with the optimized generation of electricity by means of a Combined wind turbine or the operation of a Wndenergieanlage. unused

Air flow, which results from the resulting suction when blowing out on the rotor blades, is used to aerate the rotor blades, the machine house and to supply air to the C0 ₂ collectors.

Another particular embodiment is given if before and / or after the collection of the C0 ₂ filtering the air and / or dehumidifying the air and / or desalting the air and / or dust / fine dust filtering of the air takes place since As a result, the performance of the C0 ₂ collector can be further optimized, in particular its longevity is further increased and the service intervals are significantly increased.

In the course of further improvement of the invention can be a guiding of the air through the

Components of the power plant take place in such a way that initially a cooling of

Wndenergieanlage system components and further heating and / or drying of the Wndenergieanlagenrotorblätter takes place, whereby on the one hand system components such as the generator and the electronics are cooled and on the other hand

Rotor blades are ventilated from the inside with heated air.

 Further aspects, in particular design variants according to the invention which are to be mentioned here in the course of this invention, to which even individual protection could be granted, namely with regard to an energy installation, are stated below:

 A wind turbine ventilation method, in particular for an offshore wind turbine, may also include: drawing outside air into a nacelle and / or a tower of a wind turbine, filtering the sucked outside air, at least part of the humidity and / or salinity of the drawn outside air being removed, at least Sectionally guided sucked and filtered outside air through the nacelle and / or the tower, discharging the guided

sucked and filtered outside air.

Furthermore, a wind energy plant, in particular in the offshore area, have a turbine house arranged on and / or on a tower, at least two

Energy turbine rotor blades, which are arranged rotatably in a common hub about a rotation axis and are connected via a drive train to a generator arranged in the engine house, an outside air intake device for generating an air flow within the machine house and / or the tower with a filter arrangement for filtering the outside the engine house sucked in air.

In this regard, other tasks or even subtasks or the resulting benefits could be seen in addition or individually, namely a Specify wind turbine ventilation method and a wind turbine, especially for the offshore sector, where the air needed to protect the system components within the machine house could be used to improve the life of the rotor blades and at the same time to increase the offshore wind turbine efficiency. A correspondingly advantageous wind turbine ventilation method, in particular also for the offshore sector, could have:

 - An intake of outside air into a nacelle and / or a tower of a

 Wind turbine;

 - Filtering the sucked outside air, wherein at least parts of the humidity and / or the salinity of the sucked outside air are withdrawn;

 - At least partially guiding the sucked and filtered outside air through the machine house and / or the tower;

 - discharging the guided sucked and filtered outside air,

in which

deriving the guided sucked and filtered outside air by further guiding the guided sucked and filtered outside air into the interior of the

Wndenergieanlagenrotorblätter takes place, with this further guided sucked and filtered outside air is discharged from the Waldenergieanlagenrotorblättern.

As a result, it is additionally or individually possible to aerate a Wndenergieanlage with purified, dried and / or salt-free air and thus on the one hand to maintain the nacelle and on the other hand, the hub and the Wndenergieanlagenrotorblätter sustainable because no aggressive ambient air enters the system. Through the filtered air, all internally arranged components as well as the housing, tower, hub and interior of the

Energy turbine rotor blades durably protected against harsh external conditions, especially offshore locations. Salination of internal components as well as materials and materials is prevented. The same applies in particular to C0 ₂ collectors.

In addition to improving longevity, there is also an improvement in aerodynamics.

In particular, moist rotor blades are additionally susceptible to lightning, so that this phenomenon of lightning attraction is reduced by the drying by means of the air passed through. Furthermore, bio-fouling within the rotor blades is almost excluded, since conditioned air is deliberately guided through the rotor blades.

Another aspect of this method is that the air generated by the outside air intake device in the nacelle and the introduced from the Wind turbine rotor blades quasi flung out, in addition by the

Siphoning is sucked in more strongly, so that a possibly provided compressor requires less power to provide the same amount of air. A 50 mm rotor blade of a standard wind turbine can produce a suction capacity of up to 1 bar pressure difference at a speed of 14 revolutions per minute, which corresponds to 0.33 square meters per second, so that the three rotor blades of a wind turbine could achieve a 3 bar suction, however the resulting volume flow is dependent on the cross sections and outlet bores or the air duct. From a certain rotor revolution can be dispensed with due to the suction on the normally conventional compressors, so that a passive ventilation system is realized. In particular, this passive

Ventilation system also ensure the volumetric flow supply of the C0 ₂ collector with outside air.

In the design and dimensioning of the exhaust openings, in particular the

Total passage volume in the air guide from the nacelle to the hub are taken into account. In this case, the air passage with the cross section in the transition from engine house to hub is assumed to be the maximum cross section and the others

Openings, in particular in the blade tips dimensioned and adapted accordingly.

Furthermore, when guiding the air through the components of the wind power plant, cooling of the wind turbine system components and further heating and / or drying of the wind turbine rotor blades can first take place, so that the high moisture content, in particular of the sea air, can not affect the components of the wind turbine. Particularly advantageous would be a corresponding pre-treatment before feeding to the C0 ₂ collectors.

When discharging from the turbine rotor blades, it is possible to reduce creeping and flutter by detaching flows and / or turbulences, since the discharge of the air takes place deliberately, namely at the top, the trailing edge and / or the blade tip / worm.

Through this targeted discharge, a slopping flow, which tends to become turbulent and thus reduce efficiency, is again moved into a laminar flow, which leads to an increase in efficiency.

The discharge can take place at separation points of the flow from the turbine rotor blades, so that, accordingly, a calming of the flow takes place. In addition, the wind turbine can also have:

 a nacelle arranged on and / or on a tower,

 - At least two wind turbine rotor blades, which are arranged rotatably in a common hub about an axis of rotation and a drive train with a in the

 Machine house arranged generator connected,

 - An outside air intake device for generating an air flow within the

 Machine house and / or the tower with a filter arrangement for filtering the sucked from outside of the machine house air,

in which

an air guide arrangement is provided from the interior of the machine house for air guidance of auszubringenden from the interior of the machine house air into the hub and further into the wind turbine rotor blades and further from the Wndenergieanlagenrotorblättern.

By means of this power plant, it is also possible to increase the longevity of the entire system.

The outlets may be on the top and / or rear edge of the

Wndenergieanlagenrotorblätter be arranged.

The air duct assembly from the interior of the machine house for air guidance of the auszubringenden from the interior of the machine house air into the hub can as at least one hollow bore within the drive train, the drive train seal for

 Machinery and / or the rotor shaft of the drive train may be formed so that air can be selectively directed from the nacelle into the hub and further into the rotor blades. Further, the air duct assembly from the interior of the machine house for air guidance of auszubringenden from the interior of the machine house air into the hub as a jacket tube which is formed around the rotor shaft can be configured.

The air guide assembly can be an air passage from the hub in the

Have turbine rotor blades and / or the air guide assembly can be formed as an open passage between the hub and Wndenergieanlagenrotorblätter.

The transition between the hub and the turbine rotor blades may be sealed. For this purpose, there is a minimum gap or a corresponding seal. Further or additionally, the transition between hub and machine house can be kept very low accordingly. Overall, it should be noted that due to the sucking effect of the air delivery on the rotor blades, an absolute sealing does not seem necessary, since the air from the engine house does not escape through all the gaps present, but skillfully through the combination with the rotating rotor blades through the offshore Wndenergieanlage is passed.

The advantages result in total:

 - Combination of C02 filtering with simultaneous generation of electricity through use;

- Elimination of additionally required air blowers, which ensure an air supply to the C0 ₂ collectors;

- cooling the interior of the engine room;

 - Heating and drying of the wind turbine rotor blades and the hub;

- Increasing the lifetime of the entire plant, both the wind turbine and the C0 ₂ collector;

 - prevention of salinisation;

- Reduction of the compressor power of any compressor provided by the outside air-air flow on the centrifugal forces by the rotating rotor blades;

 - Soothing the currents by targeted blowing on or on the rotor blades;

 - Acoustic reduction by the blowout in the blade tip area;

 - Reduction and elimination of the compressor capacities of the compressors for ventilation of the nacelle and

 - Reduction of the risk of lightning by leaf drying.

According to invention Wndenergieanlage 1 with C0 ₂ collector 5, in which case the C0 ₂ - collector 5 is arranged in and / or on the machine house 12.

It should be pointed out at this point that the figures described and appended below are merely intended to illustrate the invention and that they are not intended to be restrictive. Fig. 1 shows a general schematic schematic representation of a general

Embodiment of a wind turbine 1 according to the invention with C0 ₂ collector 5 in a first embodiment.

Here, within the energy plant 1, which comprises the three rotor blades 21, 22, 23 rotating clockwise in this exemplary embodiment in plan view, a C0 ₂ collector 5 is arranged, which operates weatherproof there, namely from the one in the tower 11 located outside air intake device 13 receives air supplied, which is then passed through the C0 ₂ collector 5 and is then passed through the tower in the machine house 12 and is guided by the hub 20 in the three rotor blades 21, 22, 23 wherein the air is then discharged from the rotor blade tips 26. Here, the flow direction is indicated by the arrows.

As the air flows through the C0 ₂ collector 5, a catalytic separation of the C0 ₂ from the supplied outside air takes place.

The air flow is virtually maintained by itself and requires no additional fan or pumping power in normal operation, since the centrifugal forces, the air at the blade tips 26 or generally on the rotor blades 21, 22, 23 is thrown out and so a suction arises, the more Air through the entire system 1/5 promotes.

During start - up or in times of calm, the C0 ₂ collector can continue to be operated via an additional blower. Here, in turn, a corresponding fan can be used synergistically to use the ventilation of the machine house.
