RU2265163C2 - Solar-vacuum electric power station - Google Patents

Abstract

FIELD: the invention refers to small power engineering using renewable energy sources- Sun, wind, lifting of warm air upwards, difference of atmospheric pressure throughout the height.

SUBSTANCE: The electric power station has an accumulator of solar power and a tower which is equipped with aerodynamic facilities for transformation of solar and wind energy in electric power.

EFFECT: creation, building and exploitation of solar-vacuum electric power station in small towns and inhabited localities instead of diesel power stations and boiler rooms on solid fuel, transfer from hot-water heating to electric heating on a moderate price for inhabitants and local production allows to brighten economy of these settlements.

Description

The invention relates to small energy, using renewable energy sources - the sun, wind, rising warm air up, the difference in atmospheric pressure in height.

Known air-vacuum power plant, including a greenhouse and a pipe 1 km high, in the form of a truncated cone, in the upper narrow end of which is placed a turbogenerator. This power plant uses the energy of warm air rising up the pipe (Newspaper "On the Edge of the Impossible" No. 11 (264) 2001).

The disadvantages include the narrow area of use of unconventional energy sources, the large height of the pipe, the difficulty of placing and operating multi-ton generators at high altitudes, and a lot of noise.

The objective of the invention is the expansion of the use in one installation of several non-traditional sources that complement each other and convert the energy of the sun and wind into electrical energy at the same time, or independently of each other.

The solution to which the invention is directed is achieved by the fact that the solar-vacuum power plant is made in the form of a greenhouse and filled with material that accumulates solar energy, and the pipe is made in the form of a tower of Venturi tubes placed in each other, each of which consists of two hollow truncated cones connected by smaller bases, and mounted vertically so that the upper wide base of the inner tube is placed with a gap in a narrow section of the outer, and the outer walls of the tower are made in the form of glazed "warm" boxes black heat-conducting surface for the use of solar energy, and in the upper part of the tower is equipped with a deflector for the use of wind energy, and in the lower part a vacuum tube in the form of a truncated cone, the wide base of which is placed with a gap in a narrow section of the inner Venturi, and a smaller base is connected to one or more turbogenerators, which are placed in the hall at the base of the power plant.

The drawing shows a schematic diagram of a power plant.

Designated: 1 - greenhouse, 2 - material - solar energy accumulator, 3 - internal venturi, 4 - external venturi - tower walls, 5 - glazed surface of the walls of the tower 4 in the form of "warm" boxes, 6 - black heat-conducting surface of the tower 4 7 - deflector, 8 - vacuum pipe, 9 - turbogenerators, 10 - noise muffler.

The solar-vacuum power plant is made in the form of a greenhouse 1 and is filled with solar energy-accumulating material 2, and the pipe is made in the form of a tower of Venturi tubes placed in each other, each of which consists of two hollow truncated cones connected by smaller bases, and is installed vertically so that the upper wide base of the inner tube 3 is placed with a gap in a narrow section of the outer 4, and the outer walls of the tower 4 are made in the form of glazed 5 "warm" boxes with a black heat-conducting surface 6 - for use solar energy, and in the upper part the tower is equipped with a deflector 7 for using wind energy, and in the lower part it is a vacuum pipe 8, in the form of a hollow truncated cone, the wide base of which is placed with a gap in a narrow section of the inner tube 3, and the smaller base is connected to one or more turbine generators 9, which are placed in the hall at the base of the power plant.

To protect against noise, the power plant is equipped with well-known passive and active sound absorption systems 10, located near the noise source.

The operation of the power plant (rotation of the turbogenerators 9) is carried out due to the vacuum in the pipe 8 created in the venturi 3 and 4 when the warm air rises, which is formed when the sun heats the air inside the tower through the heat-conducting surface 6 in the glazed drawers 5, and the warm air supplied to a tower of solar energy accumulators 1 and 2, as well as due to suction of air from the tower, in the wind, with a deflector 7.

The creation, construction and operation of solar-vacuum power plants in small cities and towns with an affordable price for the consumed electricity not only for domestic needs, but also for heating and for production - will revive the economies of these settlements.
