A solar thermal energy focusing system

Abstract

The solar light and thermal energy focusing system of the present invention has a dish-type reflective parabola whose focal point or focus spot shifts within a fixed range when tracking the sun, and when the sun moves in the sky, the reflective paraboloid can be tracked with the axis as the center At the same time, the reflective paraboloid can also rotate and track with the sleeve as the center. The light-collecting and heat-collecting device is installed on the fixed support surface of the fixed support device, so that the light-collecting and heat-collecting device does not need to move with the movement of the reflective paraboloid. The light-collecting and heat-collecting device mentioned above can be any device that utilizes solar energy and thermal energy, such as heat collectors, small and medium-sized thermal generators, high-energy photovoltaic cells, solar steam boilers, and photocatalytic high-temperature reactors. The center of gravity of the thermal device is just above the axis of the casing and also at the center of several supporting feet, so that the mechanism supporting the light and heat collecting device can bear more weight.

Description

technical field [0001] The invention relates to a solar thermal energy focusing system, which uses a relatively simple and economical method to realize dish or disc solar energy tracking. The solar thermal energy focusing system also involves thermal energy storage devices, solar water heaters, and solar micro boilers. Yes, solar micro-water treatment systems include seawater desalination systems, small and medium-sized solar thermal power generation systems and collectors of solar thermal power plants. Background technique [0002] The existing dish or disc reflective parabolic solar concentration tracking system is generally more complicated. The light and heat collector moves with the movement of the paraboloid, similar to a parabolic microwave antenna. If a heavier light and heat collector is required or an external pipeline needs to be connected The whole device is very complicated and expensive, and the reliability and stability are also poor, making it difficult to po...

Problems solved by technology

In order to make the light and heat collection device in a fixed position, the so-called tower light and heat collection system is currently used to reflect in a fixed range with multi-faceted mirrors, or the so-called trough light and heat collection system is used. This kind of system has been widely used, but this kind of system is generally large or medium-large and cannot be miniaturized
