Embodiment 1

[0026] Example 1: A solar diversion tower of 60m is used, the diameter of the diversion tower is 6m, the diameter of the solar collector is 500m, the height of the collector layer is 2.2m, and the high-temperature area of ​​the collector with a high concentrating lens covers an area of ​​10,000m 2 . The vertical axis wind turbine on the outer wall of the tower is coupled with the turbine generator inside the tower to perform complementary work. The top of the tower adopts a large vertical axis wind power generator, which alternates and complements power generation and transmission gears to drive the exhaust fan in the tower to pull out the wind. Experimental results: The heat collection efficiency factor in the high temperature area of ​​the high-condensing lens heat collector is increased from 0.9 to 1.5, and the efficiency is increased by 67%. When the air at 20°C enters the collector system and reaches the bottom of the diversion tower, the inlet temperature increases by m...

Abstract

The invention discloses a high-light-concentration solar-energy and hot-airflow wind/solar coupled generating system, comprising a turbine generator, turbine fan blades, a secondary-stage turbine wind generator, a third-stage turbine wind generator, a plurality of vertical-axis wind generator, a vertical-axis wind turbine, a high-light-concentration heat collecting lens, a diversion-tower inner-wall panel heat retainer, a serpentine-tube type heat collector, a Fresnel light concentrator, a high-light-concentration gallium arsenide photovoltaic cell system and a film photovoltaic cell system. The high-light-concentration solar-energy and hot-airflow wind/solar coupled generating system has the advantages that the high-light-concentration heat collection efficiency is higher than air temperature of a conventional chimney-type heat-power-generating heat collecting shed, after a high-temperature hot airflow enters the diversion tower, air speed is improved by 5-10m/S, and the generated power of turbines is improved by 30% for work application; the height of the diversion tower is reduced by more than 60%; the air negative pressure is increased, the air density is decreased, and a hot-airflow chimney effect is enhanced; the turbines are coupled with the vertical-axis generator to make up the motive power compensation caused by air speed reduction at night; the vertical-axis wind turbine drives the turbine generator to simultaneously or alternatively and independently drive the turbine generator to rotate for power generation through a gear; and thus, the all-weather continuous power generation is realized.

Description

technical field [0001] The invention relates to a power generation system of a high-concentration solar thermal airflow-wind-solar coupling tower, and belongs to the technical field of solar energy utilization. Background technique: [0002] Energy is one of the most important material bases for human survival and development. The sun is the source of life and energy for the earth. In the course of the modern industrialization of human society for only a few hundred years, the huge energy consumption makes these fossil energy accumulated after hundreds of millions of years to be exhausted. If human beings want to live on the earth To continue to thrive and develop, it is necessary to find and develop new energy sources. Large-scale development and utilization of solar energy is one of the most effective ways. The radiation energy that the sun sends to the earth every year is about 130 trillion tons of standard coal, which is equivalent to 10,000 times the sum of all kinds ...
