Small-sized waste heat and solar energy multifunctional hybrid power generation device

Abstract

The invention discloses a small-sized waste heat and solar energy multifunctional hybrid power generation device. A Fresnel lens is connected onto the top end of a pipeline; the inner part of the pipeline is a cylinder; the outer surface of the pipeline is provided with a heat preservation sleeve; the lower port of the pipeline is connected with an annular heat preservation baffle; the bottom surface of the annular heat preservation baffle is connected with an annular supporting disc; the annular supporting disc is connected with a group of fixing columns; the fixing columns pass through the annular heat preservation baffle to be connected onto the heat preservation sleeve; the diameter of the central through hole of the annular heat preservation baffle and the annular supporting disc is the same as that of the cylinder inside the pipeline; a group of porous media is arranged in the cylinder; the porous media are arranged from up to bottom; and the first porous medium is arranged at the focus of the Fresnel lens. The device of the invention is used for waste heat and solar energy multifunctional hybrid power generation.

Description

technical field [0001] The invention relates to a small waste heat and solar energy multifunctional hybrid power generation device. Background technique [0002] With the rapid development and application of solar energy technology in recent years, the trend of it replacing fossil energy as the main power generation energy in the world has been initially reflected. At present, the utilization rate and power generation efficiency of solar energy are restricted by many factors, mainly including latitude, weather, environment Uncertain factors and artificial factors such as photoelectric and thermoelectric conversion technologies are not yet mature. Because the current solar energy collection technology is relatively simple, it is useless to simply collect sunlight for power generation, and it is useless to take into account the discontinuity and intermittent power generation caused by the above factors. In addition, the thermal storage technology needs to be improved. At the s...

[0002] With the rapid development and application of solar energy technology in recent years, the trend of it replacing fossil energy as the main power generation energy in the world has been initially reflected. At present, the utilization rate and power generation efficiency of solar energy are restricted by many factors, mainly including latitude, weather, environment Uncertain factors and artificial factors such as photoelectric and thermoelectric conversion technologies are not yet mature. Because the current solar energy collection technology is relatively simple, it is useless to simply collect sunlight for power generation, and it is useless to take into account the discontinuity and intermittent power generation caused by the above factors. In addition, the thermal storage technology needs to be improved. At the same time, considering that most of the energy generated by modern fossil energy is dissipated into the space as heat, industrial waste heat has not been used efficiently, and a large amount of heat is dissipated into the air and wasted.
