Description

SUBSTANCE: invention relates to wind turbines intended for injection of atmospheric oxygen into the water of treatment facilities pools or into the water of rivers, lakes and ponds requiring ecological improvement of their flora and fauna.

Numerous similar installations are known, containing wind turbines as a drive, and various types of compressors or pumps as an actuator.

It is known, for example, "Wind wheel and the head of an automatic unit with a membrane compressor", [1], Shefter Ya. I. Use of wind energy. M, 1983, fig. 5.14, p.93.

This device contains a wind turbine, the wind wheel of which is mechanically connected to a membrane compressor containing four working chambers with air intake and discharge valves.

The disadvantages of this installation are the significant complexity of the design, requiring constant maintenance. In addition, propeller (repeller) wind wheels require average annual wind speeds of more than 5 meters per second for efficient operation, which is quite rare in the flat territories of the Russian Federation.

There is also known an installation for the production of compressed air using a wind wheel of the Darrieus type, loaded on a screw compressor, also containing a confuser channel and a compressed air accumulator [2], Kukhartsev V. V., Spiridonov A. G. Problems of compressed air production using wind turbines (MPEI ), "Industrial Energy", No. 4, 2001, p. 40.

The disadvantage of this device is also the significant complexity of the design, requiring constant maintenance by personnel. The Darrieus rotor, in addition, requires preliminary spin-up and its blades with an aircraft wing profile begin to work effectively only at wind speeds of more than 7 ... 8 meters per second.

The objective of the invention is to eliminate these shortcomings and create a device that is simple in design, does not require constant maintenance, and is capable of autonomous operation without power supply in remote areas as air oxygen blowers into the water of pools that need aerobic treatment.

The technical result of the invention is as follows:

- as an air blower, a multi-blade low-speed rotary wind turbine with a vertical axis of rotation, mounted on a bearing support, is used, and the axis is made hollow in the form of a pipe, placed by the lower part in the medium (water) into which air is injected;

- between the blades on the axis of the device there is a cylindrical storage tank for air, equipped with spring-loaded valves that open into the inside of the tank, and the upper part of the hollow pipe is placed in the tank and has perforations (holes);

- a fixed outer pipe is connected to the hollow axis-pipe through a stuffing box seal, also fixed on a bearing support, to the lower end of which hoses (tubes) with perforations distributing air are connected to release air into the water at specified distances;

- to the external fixed pipe equipped with a check valve, an additional pipeline is connected below the check valve, connected through a control valve to the oxygen cylinder.

The technical result is achieved due to the fact that in a wind turbine with blades and a vertical axis of rotation, made in the form of a pipe, a storage tank for air, closed from the top, equipped with spring-loaded valves that open inward, is installed between the blades, a vertical axial pipe placed by means of bearings on a bearing support , at one end is fixed in the container and has a perforation for air entry into it, and coaxially with the lower part of this pipe, a fixed pipe fixed on a support is connected through a stuffing box seal, to the outlet of which the perforated hoses distributing air and placed in water are connected.

The technical result is also achieved due to the fact that a non-return valve is installed in the fixed pipe, below which an oxygen supply pipe is connected to the pipe, connected through a control valve to an oxygen storage cylinder.

"Wind turbine for forcing air into the water of the pool" is shown in the drawings, where in Fig. 1 in section, a general view of the device, and in Fig. 2- view A-A.

The wind turbine contains blades 1 of the wind wheel, for example, four of the type of Savonius rotors, between the blades in the center of the device there is a storage tank for air and a closed top container 2, which also has four spring-loaded valves 3 for opening inside (Fig. 2). The support axial pipe 4, which is the axis of rotation of the wind turbine, is fixed in bearings 5 on the bearing support 6. The upper part of the support pipe, located in the storage tank, has a perforation for air inlet. The distribution of air over large areas of the reservoir is ensured by a stationary pipe 7 located coaxially with the rotating pipe through the stuffing box 8, also fixed on the bearing support and attached to it perforated (with holes) flexible hoses 9 distributing air, placed in the aquatic environment of the pool.

The base 10 of the wind turbine is placed above the water on the platform 11 of the treatment plant or directly on the ice of the reservoir to supply air or oxygen-enriched air to the fish kill zones and also to increase the viability of other aerobic aquatic organisms.

If it is necessary to use an external source of oxygen, the fixed pipe is equipped with a check valve 12, and below it, an oxygen supply pipe 13 is inserted into the pipe through the control valve 14 from the oxygen cylinder 15.

"Wind turbine for forcing air into the pool water" works as follows. Vane wind turbines of the Savonius type, the Voronin type [3], as well as other designs [4, 5, 6] with a vertical axis of rotation begin to operate at low wind speeds typical for most territories of the Russian Federation. Under the pressure of the wind flow V (Fig. 2), spring-loaded valves 3 open in turn, passing air into the storage tank 2, from which, through the perforation of the upper part of the axial rotating pipe 4, air is injected into this pipe. Further, bypassing the gland seal 8, the air enters the stationary pipe 7 and through the flexible hoses 9 connected to it with perforation is distributed over the water area of the reservoir.

For water bodies neglected in an ecological sense with dying flora and fauna, it is often not enough to supply only air for their recovery, therefore, they resort to saturating the air supplied to the water with oxygen.

Also, this technique is used in wastewater treatment plants and other different sources of heavily polluted water. In this case, the fixed pipe 7 is equipped with a check valve 12, which does not prevent the air from being pumped by the wind turbine, but does not allow oxygen to move up the pipe. When the adjustable valve 14 is opened, oxygen from the cylinder 15 enters through the tube 13 into the fixed pipe 7 and, mixing with air in the required concentration through the distribution hoses 9, is supplied to the pool water.

The proposed design also has a high efficiency, since it has only one link for converting wind energy at once into forcing air into water. In other similar multi-link installations, wind energy is first converted into mechanical energy of a generator that generates electricity, and electricity is used to drive a pump mechanically. It is known that the overall efficiency of multi-link installations will be determined by multiplying the efficiency of each link and will be significantly lower than the single-link option.

The country has a huge number of rivers, lakes, economic reservoirs, treatment facilities, etc., neglected with dying flora and fauna.

The proposed device is not difficult to manufacture, does not require power supply, does not require constant maintenance, and therefore can be located in remote areas. In view of the foregoing, this simple in design "Wind turbine for pumping air into the water of the pool" can be recommended for widespread use in the national economy.
