Thermal wind turbine

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat power engineering and may be used to provide hot water supply and heating of buildings and structures located in areas with no centralised heat and power supply. A thermal wind turbine comprises a rotor wind engine with a vertical shaft, which transmits rotary motion via a reducer to a round plate, to which vertical cylindrical partitions are fixed at the bottom, being submerged into a heat insulated tank with water. Cylindrical partitions are also fixed to the bottom of the tank, and partitions fixed on the round plate move between those. Water arriving into the tank, flowing via movable (rotary) and fixed partitions is heated due to friction. Since the gap between movable and fixed partitions is chosen as minimum possible for water passage, water heating is carried out quite effectively, which is also supported by a roll arranged in the form of a net increasing friction made on the surfaces of cylindrical partitions. Blades mounted on the outer side of the external (relative to the central axis) movable (rotary) cylindrical partition help to pump water into the outlet nozzle of the tank and back to the load.

EFFECT: higher efficiency.

The invention relates to the field of power engineering and can be used to provide hot water and heating of buildings and structures placed in areas where there is no Central heating and limited electricity, for example, in the locations of small military bases, border posts, etc.

Known thermal wind turbine to produce hot water (and.with. The USSR №1216418, Bulletin No. 9, 1986), comprising a wind wheel mounted on a vertical shaft, a tank of water placed in the tank two impeller and generator with two sealed enclosures.

Such a device is not effective enough to provide hot water.

Known thermal wind turbine to produce hot water (German patent No. 723048 published in 1942) - the closest analogue that contains a turbine with vertical shaft, at the lower end of which is secured the impeller is placed in the tank of water.

This wind turbine is insufficient to provide consumers with hot water.

The purpose of the proposed thermal wind turbines is to increase the effectiveness of hot water through the creation of more advanced installations using modern wind turbine rotor with a vertical shaft, driving the design with bol�large surface area, in contact with the water during the rotation of the surface, submerged in a tank of water.

This goal is achieved due to the fact that in the heat-wind turbine comprising a wind turbine with a vertical shaft and a tank of water, equipped with a pipe for water drainage, as the turbine is used placed on the roof of the building wind turbine rotor with a vertical shaft, for example, patent RF №221000, kinematically connected through a gearbox, also located on the roof of the building, with a circular horizontal plate to which is attached below the vertical partitions made in the form of concentrically placed cylinders, the external (relative to the Central axis) of the partition wall is provided on the outer side blades attached along generatrix of the cylinder, round plate with partitions immersed in a thermally insulated tank of water, to the bottom of the tank is attached to vertical walls, also made in the form of concentrically placed cylinders, whose diameter is selected such that the walls (side surfaces) of these cylinders is located between the walls (side surfaces) of the cylinders attached to the circular plate, and the gap between the cylindrical walls round plates and partitions the bottom of the tank was the minimum possible for the passage of water, and between the edges of torsemideorder, mounted on the circular plate and the bottom of the tank is formed by a gap, the same gap is formed between the ends of baffles mounted on the bottom of the tank and the round plate on the side surfaces of the cylindrical walls rolled forward in the form of a grid, in the center of the bottom of the tank is fixed upright pipe with plugged ends, part of the pipe located inside the tank, above the bottom cut a hole for the passage of water, and to the part of the tube located outside of the tank, attached in communication with the inlet for supplying water.

This design thermal wind turbines allows for a more efficient heating of water due to the large total surface rotating in a water cylinder for rotation using a more advanced wind turbine rotor according to the patent of Russian Federation №221000 (the patentee Sekerin A. P., author Turkin, K. N.), which, as follows from the description of the patent, does not require installation on tall mast and provides a more uniform operation of a wind turbine regardless of the strength and direction of the wind. In addition, performed on the surfaces of the cylinders roll in the form of a grid increases the friction between the plate and the fluid, i.e. more intensive heating of the liquid during rotation of the cylindrical surfaces in water, and the minimum possible gap between the rotating surfaces of the cylinder�in and fixed cylinders contributes to a more rapid heating of the water, flowing between these surfaces.

The intensity of the heating fluid in heat setting is directly proportional to the force required for uniform motion of the plate to overcome friction in the fluid, the magnitude of which can be determined by the formula:

v

where: F is the force required for uniform motion of the plate in the liquid, N.;

µ - coefficient of dynamic viscosity of the fluid, N∙s/m2;

S is the surface area of the plate, m2;

v - velocity of motion of the plate, m/s;

δ - the thickness of the layer of fluid between the movable and fixed plates, m.

Formula (1) obtained on the basis of the dependencies installed by Newton for viscous fluid flow (TSB, vol. 5, p. 604, M., Soviet encyclopedia, 1971).

Analysis of the analogues showed that the claimed technical solution is new. The novelty of this solution is that for heating the liquid it uses rotating cylindrical wall (surface), on which is rolled forward in the form of a grid. The rotation of the cylindrical surfaces is provided between the stationary cylindrical walls (surfaces), and the gap between rotating and stationary surfaces to the minimum possible for the passage of water. Mounted on the outer rotating cylindrical partition wall (cylinder) of the blade �bespechivaet the pressure for admission of heated water at the outlet of the tank and then to the consumer. The rotation of the cylindrical partitions (cylinders) by using improved wind turbine rotor.

Thus, the claimed technical solution is characterized by a new set of essential features, which gives a positive , and has signs of compliance with the criterion of "inventive step".

Fig.1 shows a thermal wind turbine, Fig.2 - form Nakata performed on the surfaces of the vertical cylindrical walls.

The installation includes a wind turbine rotor 1 with a vertical shaft 2, the gear 3 with the cylindrical gear 4 (the gear train, in which the diameter of the drive gear is larger than the diameter of the driven, in the subject invention is not included in the formula are not represented). The wind turbine 1 and the gear 3 is fixed to the roof 5 of the building. To the output shaft 6 of the gear 3 is attached to a horizontal circular plate 7. The lower end of the shaft 6 is provided with a coupling 8 (coupler 8 in the subject invention is not included in the formula are not represented). To the plate 7 is attached at the bottom of a vertical cylindrical partition 9. External (relative to the Central axis) of the partition wall 9 is provided on the outer side of the blades 10. Round plate 7 with partitions 9 are immersed in a thermally insulated tank 11 with water. In the lid 12 of the tank 11 is fixed in the centre of the gland 13, tor� which passes rotatably shaft 6 (the packing 13 in the subject invention is not included in the formula are not represented). To the bottom 14 of the tank 11 is attached vertically arranged cylindrical walls 15 disposed between the cylindrical walls 9 with the minimum possible gap 16 for the passage of water. Between the edges of the walls 9 and a bottom 14, and between the circular plate 7 and the edges of the partition walls 15 are formed by gaps 18 and 19 respectively. In the center of the bottom 14 is secured upright pipe 20 with plugged ends. At the upper end of pipe 20 is fixed to the bearing 21 to rotate the clutch shaft 8 and 6 (bearing 21 in the subject invention. In the pipe 20 (above the bottom 14 of the tank 11) cut a hole 22 for the passage of water into the tank 11, and below the bottom 14 of the pipe 20 is provided with a pipe 23 for supplying water. The nozzle 24 is designed to supply heated water to the consumer. The mounting of the wind turbine 1 on the roof 5 of the buildings is provided by fasteners 25 (in the subject invention are not included).

Thermal wind turbine operates as follows. The wind starts to rotate the rotor of a wind turbine 1 wind turbine rotor device shown in the patent specification No. 2210000). Together with the rotor and rotates a vertical shaft 2 of the turbine 1 and the leading and the driven cylindrical gear reducer 4 to 3. Since the driven gear has a diameter smaller than the leading, the number of revolutions of the output shaft 6 of the gear 3 is increased. In accordance with op�piss of a wind turbine 1 according to the patent No. 2210000 the number of revolutions of the wind turbine is stabilized due to the presence in its structure of the flywheel. Together with the shaft 6 rotates at a fixed circular plate 7 and attached thereto a cylindrical partition 9. Through the pipe 21, the pipe 20 and the hole 22 in the water tank 11 and through the gaps 16 is poured between the vertical cylindrical walls 9 and 15, when heated by friction. Since the gaps 16 between the rotating baffles 9 and the fixed partitions 15 selected small as possible, flowing between the partitions, the water heats up quickly and intensively, which also contributes to applied on the surfaces of the partitions 9 and 15 of the reel in the form of a grid, increasing the friction. Fixed to the outer surface of the rotating outer walls 9 of the blade 10 to facilitate mixing of the heated water to the outlet nozzle 24 and further to the consumer. If the wind speed increases, and increases the number of revolutions of the rotor of the wind turbine 1 and a circular plate 7 with the cylindrical walls 9, therefore, in accordance with formula (1) increases the force required for uniform movement of the partitions 9 in water, in proportion to the intensity of water heating.

Thus, the proposed thermal wind turbine provides efficient heating of water that can be used either for hot water or heating of buildings and structures without the need of electricity consumption, because you are using the force of the wind, the wind turbine uses a more advanced design that does not require the construction of high mast and very dimensional propellers.
