Abstract

The invention relates to veterinary technology and allows separation from mechanical impurities and flow stabilization. The support 1 has a protective cap 7 and openings made in the walls 3 and the end 2 with controlled louvers 4. The entrance mouths 5 of the sockets 6, located in the support cavity, are concentric with the openings. The central bell is straight and vertical. The mouth 10 of the latter is installed in the Venturi nozzle 9, and the mouth of the other sockets are equipped with controllable swirlers 12 flows. The nozzle is fixed in the center of the partition 8, above which drainage holes 13 are made. When opening the louver, the flow through the sockets is directed downwards, cleaned of impurities using swirlers, and then directed through the venturi nozzle to the converter elements. With a lack of energy, the blinds are turned on the mouth of the central socket and the flow from under the cap is sucked into the Venturi nozzle, which increases the performance of the conversion element. 1 hp ff, 2 ill.

the supports placed in the cavity are concentric. The central bell is straight and vertical. The mouth 10 of the latter is installed in the Venturi nozzle 9, and the mouth of the other sockets are equipped with controllable swirlers 12 flows. The nozzle is fixed in the center of the partition 8, which is provided with drainage holes 13. When the louver opens, the flow through the sockets is directed downwards, cleaned of impurities using swirlers, and then directed through the venturi nozzle to the converter elements. With a lack of energy, the blinds are turned on the mouth of the central socket and the flow from under the cap is sucked into the Venturi nozzle, which increases the performance of the conversion element. 1 hp f-ly, 2 ill.

The invention relates to veterinary and can be used in wind turbines of a tower type.

The purpose of the invention is the separation and stabilization of wind flow.

FIG. 1 shows a diagram of the device; in fig. 2 shows swirl flow control circuit.

The device for wind flow concentration comprises a vertical hollow support 1 with a closed upper end 2, the side walls of which 3 have openings, closed louvers 4 connected to the inlets of the sockets 5 of curvilinear shape. The device additionally contains a protective cap 7 mounted on a support 1, equipped with a horizontal partition 8 with a fixed in its center

By means of a Venturi nozzle 9 and a support 1 located in the lower part. The arms 6 are mounted coaxially, the central of which is made straight and its outlet mouth 10 is placed inside the 9 of the Venturi nozzle, and the entrance is supported by an end 2 of support 1 in which 11 with louvers 4, the outlets of the peripheral sockets 6 are located above the Venturi nozzle 9 and are equipped with flow swirlers 12, and drainage holes 13 are made in the lower part of the support 1 above the partition 8 and are equipped with a control system 14 that drives 15 which placed outside on the wall of the support 1. Below the nozzle 9 is placed a wind wheel or a turbine with a generator (not shown).

The device works as follows.

Before using the device, all blinds 4 are closed. Then, depending on the direction of the wind, they open

the louver 4 on the windward side of the side wall 3. The louver 4 is opened by a certain amount depending on the energy required by the consumer.

The wind entering the mouth 5 of the inlet of the bell 6, goes deep into the narrowing curvilinear channel of the bell 6, in which it compresses and increases its speed. At the outlet of the socket 6, the flow enters the swirler 12, where it changes its direction of rotation to a rotational one in the form of a vortex. Under the action of inertial forces, the mechanical particles in the flow, such as dust, snow, and water droplets, are thrown against the inner wall of the support 1 and roll down the partition wall 8, from where they are removed through the drainage holes 13 as they accumulate.

The air cleared of inclusions rushes into the nozzle cavity § and further onto the propeller blades or turbines.

If there is not enough air mass due to the fall of the head of the wind flow to produce the energy required by the consumer, then open the louver 4 at the entrance to the central bell 6. Then, under the action of low pressure that occurs in the cavity of the nozzle 9, additional volumes of air are sucked through the outlet mouth 10 most of its mass is fed from the holes 11 to the converter elements (wind wheel or turbine).
