Process for generating energy

The present invention relates to a method for generating energy by a power plant and/or from an air flow, in particular from a wind and/or exhaust gas flow, by means of an impeller, as well as a device for carrying out the method.

Power plants are known and used today in a wide variety of forms and designs. They are used as facilities mostly to generate electrical energy, whereby chemical, nuclear, thermal or potential mechanical energy is fed into power plants, which is first converted into mechanical energy and used to drive electrical generators, usually three-phase generators.

Power plants can be used in different ways due to their physical conditions and have different problems. Steam and nuclear power plants, for example, are only

limited controllability. They are therefore described as base load power plants, as are run-of-river hydroelectric power plants. Peak power plants, such as hydroelectric power plants, pumped storage power plants, air storage gas turbine power plants, etc., are used to cover peak loads. Geothermal power plants are also known, which extract heat from great depths in the earth, which can be further processed or used.

Furthermore, various wind turbines are known that are driven by rotors and generate electricity using generators. Also worth mentioning are solar power plants, in which the sun's radiation is concentrated using a paraboloid and a heat exchanger is heated in a combustion tower. Solar energy can also be converted chemically.

The disadvantage of these conventional power plants is that they are usually very complex and expensive to build and can only be operated with one or a few substances or with only one medium. For example, coal-fired power plants can only be operated with coal, hard coal, lignite and possibly heating oil. In contrast, nuclear power plants are only operated with plutonium or heavy water, whereby sufficient water must be available for cooling. Hydroelectric power plants also need a favorable location in order to be able to generate enough energy. Here, too, operation is only possible with considerable quantities of water. The same applies to solar systems.

The present invention is based on the object of creating a method and a device which eliminate the above-mentioned disadvantages, which can be used universally even in smaller environments and which use several energy forms to generate energy.

This task is solved by directing the wind and/or exhaust gas flow through a channel with a plurality of impellers arranged one behind the other.

This makes it possible to use a wind and/or exhaust gas stream multiple times. This is particularly important in order to increase the efficiency of the process.

If the channel is exposed to a wind current, it is important that the channel is correctly aligned with the wind current. Its long axis should be in the direction of the wind, so that the air can flow through it properly and with as little turbulence as possible.

In order to improve the efficiency of the method and device according to the invention, it is planned to provide the channel with nozzle-like constrictions, between whose narrowest cross-sections the impellers are inserted. The contours of the constrictions are designed like Laval nozzles in order to create low-loss flow conditions in the channel. The volume flow, in particular the wind and exhaust gas flow, is maximized in the narrowest cross-section of the constriction, so that a significantly higher speed of the impeller is achieved.

Of course, it is within the scope of the invention that several such constrictions with impellers are arranged one after the other in a channel. A different design and arrangement of the constriction is conceivable, whereby different impellers with different speeds can be used individually.

It is also planned to pivot or rotate the blades of the impeller so that the pitch of the blades changes to the axis of rotation in order to achieve a selectable rotation speed and thus an adjustable

This allows the speed of the impellers to be regulated on the one hand and the speed of the volume flow in the duct on the other hand, since this should have a minimum speed.

The present invention also aims to create a power plant in which a channel as described above is preferably arranged vertically and is connected to a heating device via a line. An exhaust gas flow from the heating device is guided into this channel and also flows outwards as a result of temperature differences, so that several impellers can be driven in the channel in order to generate additional electrical energy.

A special feature of the present invention is that the heating system can be operated with all conceivable fuels. This means that every community, every small village, every city has the opportunity to convert the energy available to it.

The fuels to be used should primarily be those that are available free of charge and mostly unused. These include unprocessed trees from the surrounding forests, garden waste and other municipal waste. Not only can energy be generated from these materials, but the forests are also kept clean and the waste is put to good use. There are also plans to grow fast-growing plants through the sensible use of agricultural land and later use them as fuel. This could bring additional profits to agriculture.

It is also possible to use the exhaust gas from digestion towers as fuel. In digestion towers, bacteria from sewage sludge and manure or similar produce methane gas, which is ideally suited as fuel.

Furthermore, parts of a compost can be used to generate energy after sufficient drying, for example in warehouses, thus also solving a waste problem.

However, the use of fossil fuels such as oil and natural gas can also be considered.

To ensure that such a power plant is not solely dependent on fossil fuels, wind turbines are also arranged on the channel designed as a chimney, which are aligned against the wind and, if necessary, turned into the wind or the wind turbine is aligned.

Furthermore, unused areas of the power plant and in particular the building areas will be equipped with solar cells in order to generate energy there as well.

Overall, a power plant is created that uses different energies and is much easier to control.

For example, load differences can be compensated for by means of adjustable impellers through adjustable heating processes, with wind energy and solar energy forming a basis and additional support.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing, which shows in

Figure 1 is a schematic view of a power plant according to the invention for generating energy;

Figure 2 shows a longitudinal section through an inventive channel of the power plant according to Figure 1;

Figure 3 shows a longitudinal section through another embodiment of the channel according to Figure 2.

According to Figure 1, a power plant R according to the invention has a heating device 1, which is preferably operated with fuels 2. The fuels 2 are converted into thermal energy in the heating device 1 by burning. Fossil fuels are used, but also trees, bushes, etc. that are harvested in forests and otherwise not used. In addition, fuels 2 can be grown through sensible use of agricultural land, with fast-growing plants being considered. This makes a major contribution to environmental protection, since otherwise unused fuels 2, for example from forests or waste, are used to generate energy.

The heat generated can be further used via heat exchangers not shown here, whereby according to the invention a waste heat flow, in particular an exhaust gas flow 3, is led through a line 4 into a channel 8 according to the invention. This is placed on the power plant R like a chimney and is therefore preferably arranged vertically.

At least one impeller 9.1, 9.2, 9.3 is inserted into this channel 8, whereby the individual impellers 9.1, 9.2, 9.3 are arranged one after the other in the channel 8.

The volume flow formed as exhaust gas flow 3 is guided upwards in the channel 8 through the individual impellers 9.1, 9.2 and 9.3, which are thereby driven. The impellers 9.1, 9.2 and 9.3 are assigned generators, which can convert the rotary energy into electrical energy.

Furthermore, the channel 8 is assigned wind turbines 5.1, 5.2, which are arranged outside the channel 8 and can be aligned in the direction of the wind due to their ability to rotate. These wind turbines 5.1 and 5.2 preferably also consist of a channel 8.1 or 8.2, in which impellers 9.4 and 9.5 are inserted. These impellers 9.4 and 9.5 are in turn connected to generators (not shown in detail) and generate energy through a wind current 6. Each wind turbine 5.1 or 5.2 is connected to a slewing ring 16 via a holder 15.1 and 15.2, so that the wind turbines 5.1 and 5.2 can rotate relative to the channel 8 and face the wind. This rotation is indicated by the arrow ring 17.

In addition, solar cells 7 are assigned to power plant R on unused areas, such as roofs or similar, in order to use these unused areas to generate energy.

To ensure that the exhaust gas flow does not pollute the environment and that the impellers 9.1 - 9.5 are not contaminated, filter systems (not shown here) are connected to line 4 to remove impurities from the exhaust gas flow.

According to Figure 2, a section of the channel 8 is shown with several impellers 9.1 to 9.3, 9.6, wherein an impeller 9.1 to 9.3, 9.6 has several blades 11 which are attached to a hub 10 and are rotatably mounted there.

It is intended to rotate these blades 11 so that a pitch relative to a rotation axis 12 can be changed, in order to vary the rotation speed and to adapt it to the volume flow, in particular the exhaust gas flow 3 and the wind flow 6.

In a further embodiment according to Figure 3, a channel 8.1 is shown, the channel wall 13 of which has several nozzle-like constrictions 14.1, 14.2, into which impellers 9.1, 9.2 are inserted. These constrictions 14.1, 14.2 run in a wave-like manner in the channel 8.3, so that between a constriction 14.1, 14.2 the flow velocity is greatest, which the impeller 9.1, 9.2 uses to generate energy.

With these higher flow speeds, significantly higher rotation speeds of the impellers 9.1 to 9.3, 9.6 are achieved, which leads to better energy utilization. The possibility of shaping an inner wall 13 of the channel 8.3 in a nozzle-like or wave-like manner and a correspondingly adjustable pitch of the blades 11 relative to the hub 10 enables precise adjustment and regulation of the electrical current to be generated, so that the electrical voltage generated can be kept constant during operation.

The constrictions 14.1, 14.2 before and/or after the narrowest cross-section are designed like Laval nozzles in order to reduce flow losses, in particular laminar and turbulent flow losses, to a minimum.

Here too, other shapes and designs of constrictions 14.1 and 14.2 are within the scope of the present invention, whereby it is also intended to form individual constrictions of different strengths in order to

to be able to use different impellers with different performance levels.

These impellers can rotate from top to bottom or from top to bottom.

bottom to top varying, or continuous

be changed to direct the exhaust stream 3 and wind stream 6 to

every point in channel 8.3 to be used optimally, since

whose speed and temperature can change within the channel.
