Description

The invention relates to devices for the heat and power supply of residential buildings (objects) using energy systems operating on renewable energy sources, in particular to devices operating due to artificial constantly directed steady air flow.

Energy systems are known in which the electricity generated by installations on renewable energy sources (wind, wave, photovoltaic stations, etc.) is delivered directly to the load (consumer). At the same time, problems arise in ensuring the quality of energy caused by the instability of the energy flow in the source (the wind strength, the intensity of the waves, the flow of light energy, etc.). To smooth out fluctuations in the generated power and to coordinate the latter with the power consumption mode, energy storage batteries are used: electric batteries, air storage units, pumped storage power plants, etc. (Materials of the Soviet-Japanese Energy Symposium Irkutsk: 1980, p. 277-283). The energy generated by installations on renewable energy sources in light wind, solar radiation, waves, etc., is not used, since the quality (sinusoidality, voltage, frequency and power) does not satisfy both the operating conditions of the pump motors (pumps do not work, exit electrical windings), as well as the consumer, who must continuously receive stabilized electricity from the hydrogenerator.

The closest in technical essence and the achieved positive effect to the claimed invention is a wind turbine for the production of electricity (RF Patent No. 2094651, IPC F 03 D 3/02, 1997), containing a pipe and two wind turbines (wind turbines), consisting of a blade propulsion with an electric generator, while the wind turbine is mounted on the output end of the chimney.

A disadvantage of the known wind turbine is the impossibility of energy supply of a residential building (facility) located in hard-to-reach or remote places.

The technical result of the proposed technical solution is aimed at creating the design of the installation for energy supply of local residential buildings (objects) from an autonomous energy installation due to the artificial constantly directed steady air flow.

The technical result is achieved by the fact that the autonomous air power installation comprises a duct made in the form of a pipe and a turbogenerator mounted on the upper end of the duct, and a heating device consisting of a metal pipe is placed inside the duct at a distance of 70 to 100 cm from the lower intake opening heating and burner (converter), while the metal pipe for heating is installed in an insulating casing with an annular gap with respect to the inner wall of the insulating casing, and in The air duct and the insulating casing have a hole in which a burner (converter) is placed, connected via a pipeline to a fuel tank, while on the inner surface of a metal pipe for heating in its upper and lower parts tubular electric heaters are placed, connected electrically to a turbogenerator, in addition, the lower intake hole of the duct is five times larger than the upper outlet, and the height of the entire duct must be at least fifteen meters.

The duct can be made of metal, and tubular electric heaters are placed in the inner cavity of the insulators, and they are installed above and below the upper and lower boundaries of the metal pipe for heating.

Distinctive features of the prototype is that inside the duct at a distance of 70 to 100 cm from the lower intake opening is placed a heating device consisting of a metal pipe for heating and a burner (converter), while the metal pipe for heating is installed in an insulating casing with an annular gap in relation to the inner wall of the insulating casing, and in the wall of the duct and insulating casing a hole is made in which a burner (converter) is placed, connected via a pipeline to the fuel a distinct capacity, while on the inner surface of the metal pipe for heating in the upper and lower parts there are tubular electric heaters connected electrically to the turbogenerator, in addition, the lower intake opening of the duct is five times larger than the upper outlet, and the height of the entire duct must be at least fifteen meters.

The duct can be made of metal, and tubular electric heaters are placed in the inner cavity of the insulators, while they are installed above and below the upper and lower boundaries of the metal pipe for heating.

The proposed power plant allows you to supply cheap electricity to homes (buildings) in remote or remote places, and especially in the Far North or Far East, where fuel raw materials must be imported.

Figure 1 shows a General diagram of the proposed autonomous air power plant, figure 2 - a heating device for an duct made of brickwork or concrete rings, figure 3 - a heating device for an duct made of metal.

A stand-alone air power plant comprising an air duct 1 made in the form of a brickwork pipe or concrete rings, and a turbogenerator 2 mounted on the upper end of the air duct 1. The turbogenerator is located on the flat roof of the structure. Inside the duct 1, at a distance of 70 to 100 cm from the lower intake opening 3, a heating device is arranged, consisting of a metal heating pipe 4 and a burner (converter) 5. In this case, the metal pipe for heating 4 is installed in an insulating casing 6 with an annular gap 7 in relation to to the inner wall of the insulating casing 6.

A hole 8 is made in the wall of the duct 1 and the insulating casing 6, in which a burner (converter) 5 is placed, connected by a pipe 9 to a fuel tank 10. On the inner surface of the metal pipe 4 for heating, tubular electric heaters 11 are connected in their upper and lower parts electrically with a turbogenerator 2.

The lower intake hole 3 of the duct 1 is five times larger than the upper outlet 12, and the height of the entire duct 1 must be at least fifteen meters.

For the duct 1 made of metal, tubular electric heaters 11 are placed in the inner cavity of the insulators 13, while they are installed above and below the upper and lower boundaries of the metal pipe for heating 4, while the tubular electric heaters 11 are electrically connected to the turbogenerator 2.

The heating device is designed to create traction, namely, artificial constant directional steady air flow.

Tubular electric heaters 11 are designed for a closed cycle of the installation from the turbogenerator 2 and the further creation of traction.

The insulating casing 6 is designed to preserve the heat of the heated metal pipe 4, and the annular gap 7 is designed to exit the exhaust gases of the burner 5.

The installation works as follows.

To start the installation, a burner (converter) 5 is lit, which runs on any fuel (fuel oil, diesel fuel, gasoline or gas). The flame of the burner (converter) 5 heats the metal pipe 4 to a temperature above 200 ° C, in the duct 1 there is a pressure difference due to the temperature difference heated at the intake opening 3 of the duct 1 and cold at the outlet 12 of the duct 1. The taper of the duct 1 allows you to seal and accelerate the artificial directional steady air flow and increase its driving force.

The directional air flow drives the turbine 14 of the turbogenerator 2, which operates without interruption when directed to the turbine blades of stable air flows with constant pressure. Such "organized" air flows always rise in the duct 1 due to the density difference between the lower intake port 3 and the upper outlet 12 of the duct 1. Further, electricity is generated by converting mechanical energy into electrical energy. Subsequently, it is possible to turn off the burner 5 and turn on the tubular heaters 11. A small part of the generated electricity by the turbogenerator 2 is used to heat the tubular heaters 11, while the process of artificial air flow (traction) does not stop until it is necessary to carry out maintenance of the proposed installation or turn off the installation for any other reason.

The main part of the generated electricity goes to household needs (electricity, heating, etc.).

The proposed autonomous air power plant is easy to manufacture, economical to operate, the operation of which does not depend on natural phenomena. The raw material resource is practically inexhaustible.
