The invention relates to wind power engineering and can be used to create plants with a wind turbine with vertical axis of rotation, in particular for creating aerodynamic geliostantsy. The technical result consists in increasing the efficiency of a wind plant provided by the fact that in a wind plant comprising an exhaust tower, the wind wheel, and means forming vertical workflow according to the invention is administered fan located at the stack axis and creating at the upper end thereof air flow in a plane perpendicular to the axis of the tower, while the tower is in the form of two coaxial cylinders with a working space between the outer and inner cylinders and the wind wheel blades are arranged outside the tower in the area working stream exiting therefrom.
DESCRIPTION OF THE INVENTION
The invention relates to wind power engineering and can be used to create plants with a wind turbine with vertical axis of rotation of the vertical operating workflow, particularly when creating solar plants.
Wind turbines with vertical axis, used in wind installations working in specially generated vertical workflow. It is formed either by changing the direction of the wind, or organizing an upward heat flow, as is done in the helio-wind power plants.
Known wind plant, which is formed by a vertical workflow (1). It contains a chimney and wind wheel. Formation of a workflow implemented by the air flux concentrator, configured as a tent, and inserted into it with a concave conical surface. The exhaust pipe is placed on the neck of the airflow concentrator. The lower part of the tube located wind wheel.
The device operates as follows. Horizontal air flow using the flow and inserted into it a cone concentrator is converted into the workflow, incident on the propeller blades, which then enters the chimney.
Assignment tube is to increase the working speed of flow by creating a pressure difference at the bottom and top of the tube.
The disadvantage of the installation is the low efficiency of its work. This is because the placement of the propeller tube inside the exhaust flow rate decreases the operating efficiency and reduces the impact on the exhaust pipe installation work.
The closest, taken as a prototype, is wind turbine (2). It comprises a stack built into it means forming vertical working stream inlets formed in a system, and wind wheel disposed in the upper end of the tower. To improve the efficiency of the plant introduced therein extractor device arranged at the top of the tower, formed as a cup segment certain radius and depth.
The device operates as follows. The flow of air via the air intake system is converted into a vertical workflow, resulting in the rotation of the wind wheel. After the propeller exhaust air enters the hood. In the presence of wind above the upper end of the stack creates an air stream, perpendicular to the axis of the tower, as a result of the pressure in the upper end of the tower is reduced, the flow rate of working is increased, and increased plant capacity.
However, the hood is formed as a segment of the cup is a passive element acting on the workflow, and acts only in the presence of wind. It can not be used in wind installations in which are formed vertical heat fluxes, as is done, for example, in wind geliostantsiyah.
Furthermore, the location within the stack propeller reduces the flow rate of the working and does not allow full use of the stack effect to increase the efficiency of the installation.
The disadvantage is the low efficiency of the installation.
The purpose of the invention - improving installation efficiency.
The technical result is achieved in that in a wind plant comprising an exhaust tower, the wind wheel, and means forming vertical workflow introduced fan located on the axis of the stack, creates on its upper end the air flow in a plane perpendicular to the axis of the tower, with the tower It is in the form of two coaxial cylinders with a working space between the outer and inner cylinders and the wind wheel blades are arranged outside the tower in the area working stream exiting therefrom.
The air flow generated over the upper end of the tower, reducing the pressure on it, as a result of operating the tower at the flow rate increases, while the working flux at the outlet of the tower is rejected. This impact on the workflow allows you to put the wind wheel out of the stack as a result of operating the flow rate in the tower is not reduced because the blades of the wind wheel, located in the workflow area, are not an obstacle to its movement in the stack.

Scheme aerodynamic arrangement is shown in FIG. The installation comprises means forming a workflow 1 coaxially disposed outer cylinder 2 and a closed bottom inner cylinder 3, forming the working area of the stack between the outer and inner cylinder, the fan 4 disposed on the tower axis and mounted at the upper end of the inner cylinder 3 of the stack, and wind wheel 5 located outside the tower in the workflow area. A device forming a working stream 1 is performed in different ways, depending on the type of installation. In the case of wind turbines, it may be formed as a guiding system, as in the installation (2). Ventilator 4 may be in the form enclosed in the impeller housing, creates a radially directed air flow in a plane perpendicular to the axis of the tower above the upper end of it in the area between the inner cylinder and an outer cylinder 2 of the stack 3. The impeller is rotated by an electric motor and located in a housing which can be made in the form of two circular discs with holes in the center, which receives air from the environment to create a directional air flow over the upper end of the stack. |
The device operates as follows. With the device 1 is formed by the working stream that enters the working zone exhaust pipe. Simultaneously, above the upper end of the stack with a fan creates airflow groove perpendicular to the axis of the tower. As a result of the pressure of the flow at the upper end of the working zone of the tower is reduced, which leads to an increase of the working flow rate, but also to its rejection. When you exit the tower workflow reaches the blades of the wind wheel 5 located outside of the tower, and causes the wheel to rotate.
The proposed solution improves the efficiency of the plant by increasing the speed of the workflow as a result of the fan, but also eliminate the obstacles to the working of the flow in the stack.
