Description

The invention relates to the field of vortex power plants, and more specifically relates to the creation of vortex power plants that convert the energy of the upward flow together with the energy of the incoming air currents.

Known vortex wind turbine, in which the incoming air flow is twisted and accelerated using profiled inlet channels formed by spiral guide baffles (USSR Author's Certificate N 1657723, IPC F03D 3/04, publ. 23.06.1991). In this case, the kinetic energy of the air flow is converted into vortex energy, which is converted by a wind wheel into mechanical, and then into electrical energy. To increase the efficiency of a wind turbine, the air flow with the help of curved guides is converted into swirl-shaped swirling flows (RF Patent N 2002981, IPC F15D 1/00).

The closest analogue of the claimed invention is (Patent RU No. 2093702 C1, IPC F03D 3/04, publ. 01/20/1997) a vortex wind turbine containing an exhaust device, a housing, a guiding apparatus made in the form of hollow elements in the form of truncated hyperboloids coaxially installed in the housing rotation, with dividing vertical partitions, curved in a spiral, and a wind wheel made in the form of a body of revolution with rigid profiled blades and mounted above an exhaust cylindrical channel formed by an internal torus With the help of vertical profiled partitions, a vertical axisymmetric channel is made in the base of the lower guide vane, in which a turbine is installed - an energy converter with an electric generator. A vertical axisymmetric channel is used to eject an additional air stream into the housing. Axisymmetric openings are also made at the base of the lower guiding apparatus for using upward heat fluxes.

To increase the energy efficiency of a wind turbine, the exhaust device is equipped with an aerodynamic accelerator. The wind turbine has a modular design with an increase in the flow area and air flow through each subsequent module along the height of the installation.

The device of the whirlwind wind turbine is equipped with an automatic control system that regulates the cross section of the input channels of the guide vanes.

The disadvantage of the described vortex wind turbine, adopted as a prototype of the invention, is that it is intended only for converting the energy of the incident air stream.

The task of the vortex gas-wind power installation is to generate electricity using the kinetic energy of the exhaust gas flows and, as a result, the efficient use of the incident wind flow. As well as an increase in electric power due to an ejection increase in the gas-air flow rate, even in cases of zero wind speed, an increase in the consumption of gas-air mixture and electric power due to the use of an aerodynamic accelerator - a Venturi, which is self-installing in the direction of the wind flow.

The problem is solved due to the fact that the vortex gas-wind power installation containing a housing of hyperbolic shape, an exhaust device, a turbine, an electric generator, an input guide apparatus with air channels separated by vertical partitions and made in the form of rotation hyperboloids, an axisymmetric channel at the base of the input guide apparatus with air channels, the turbine is connected by a common shaft with the rotor of the generator, according to the invention, the axisymmetric channel is equipped with swirling guides, in the upper part of the casing there is a fairing with an electric generator placed inside it and enclosed in a casing; in the annular gas-air gap between the casing and the cowl casing, blades of an axial guide apparatus and a single-stage axial turbine are installed; bearing on the housing of the unit and equipped with an airflow guide device.

Figure 2 shows a cross section along aa of the input guide vane with air channels. Here 11 are vertical partitions made in the form of hyperboloids of revolution and curved in a spiral.

Vortex gas-wind power installation works as follows. A gas stream (for example, spent in a gas turbine installation of a gas pumping unit) with a temperature of up to 450 ° C exits through the outlet channel 1 with swirling guides and enters the lower axial part of the housing 3 of a hyperbolic shape. The flow of gases due to their high temperature has a much lower density than atmospheric air, due to which rarefaction occurs in the lower axial part of the housing due to self-traction. The rarefaction value further increases due to the toroidal effect caused by swirling the air flow entering the housing 3 in the inlet guide apparatus 2 with air channels separated by vertical partitions made in the form of rotation hyperboloids and curved in a spiral. The gas-air mixture toroidally twisted along the height of the casing 3 enters the blades of the axial guide apparatus 6 through the annular gap formed by the casing 3 and the cowl cover 4, and enters the single-stage axial turbine 7, doing useful work and leading the generator rotor 5 to rotate through a common shaft The guiding device 10 provides rotation with the help of the bearing 8 of the aerodynamic flow accelerator - Venturi pipe 9 relative to the stationary body 3 and sets it along the incoming air flow. By accelerating in the venturi, the air flow creates a vacuum in its narrow section, due to which the useful work of the axial single-stage turbine 7 and the generation of electricity in the electric generator 5 are increased. In the narrow section of the venturi 9, the air flow entering through its input end section is mixed, and gas-air flow entering a narrow section of the venturi 9 from the upper part of the housing 3. The combined air flow through the outlet end of the venturi 9 is discharged into the atmosphere.

The use of vortex gas-wind power plants allows you to:

- effectively use the incident wind flow to generate electricity;

- increase the electric power of the installation due to the ejection increase in gas-air flow, even in cases of zero wind speed;

- increase the flow rate of the gas-air mixture and the electric power of the installation through the use of an aerodynamic accelerator - a venturi, which is self-installing in the direction of the wind flow.
