Embodiment Construction

[0021] In the wind tower type power generation device of the present invention, the air flow channel partitions 2 are evenly distributed along the upper circumference of the base 9, and the number of air flow channel partitions 2 is determined according to the application, so that it can maximize the use of air blown from all directions. The wind from the air channel inlet 1 to the air channel outlet 5 gradually reduces the air channel section, thereby realizing the acceleration of the air flowing in the air channel according to the basic principles of fluid mechanics; the transparent top cover 3 can be integrated Type, can also be a splicing type, used to meet the application requirements of buildings of different scales; heat absorbing material 4 is a long strip floc or grid type, arranged in a single layer or multi-layered distribution, suspended in the air flow channel Inside, under the transparent top cover 3, it is used to absorb the solar radiation heat energy passing th...

Abstract

The invention discloses a tower type solar-wind generating set and a solar-wind generation method. The generating set mainly comprises transparent top caps, a heat-absorbing material, air flow passage baffle plates, an impeller, a generator, a generator bracket and a base. Air enters air flow passages along air flow passage inlets, flows to an air flow passage outlet, and fast flows out from the air flow passage outlet converged at a central top under the acceleration function of the gradually narrowed air flow passages so as to drive the impeller at the outlet to rotate and drive the generator to work and generate electricity; and one or more layers of heat-absorbing material are arranged in the air flow passages, and absorb solar radiant heat energy under the condition of solar radiation by day to heat and expand the air in the air flow passages so as to increase a pressure difference between the interior of each air flow passage and an external environment, increase the velocity of the air at the air flow passage outlet at the tops of the air flow passages, improve generation efficiency, and reduce the volume of the generating set, particularly the volume of the rotating impeller. The tower type solar-wind generating set and the solar-wind generation method have the advantages of high applicability, high energy source utilization rate, environmental-friendliness and vast popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of low-carbon energy, in particular to a device and method for comprehensively utilizing wind energy and solar thermal energy to generate electricity. Background technique [0002] With the development of economy and society, the energy consumed by human production activities and daily life is increasing day by day, and the fossil energy such as coal and oil is decreasing day by day on a global scale. In addition, the problem of environmental pollution caused by the use of conventional energy is very serious. The energy crisis and The impact of climate change has drawn great attention from the international community. The development of low-carbon energy such as solar energy and wind energy is the fundamental way to achieve sustainable development. [0003] Wind energy is an important renewable energy with outstanding advantages such as cleanliness and environmental friendliness. As the fastest growing and...
