Solar energy light gathering and heat collecting method and system

Abstract

The invention provides a solar energy light gathering and heat collecting method, which comprises a reflecting device, a supporting controller and a heat collector, wherein the reflecting device consists of a plurality of reflecting mirror panels. The method comprises the following steps: installing the heat collector and the supporting controller; respectively installing the reflecting mirror panels on the supporting controller in a way that the reflecting surfaces face upwards; presetting the angle of the supporting controller; and presetting the rotation time interval of the supporting controller. The novel solar energy light gathering and heat collecting method has the advantages of simple steps and easy operation. A heat collecting plate is separated from reflecting mirror surface groups for sharing one heat collecting plate, so the equipment cost is greatly reduced, in addition, the heat is highly concentrated, the temperature of the heat collecting plate can reach more than 300 DEG C, the height of reflecting mirrors and the heat collecting plate from the ground surface can be reduced, and the structures of a metal support frame and auxiliary equipment can be simplified. The reflecting mirror panels have wide raw material sources and low cost.

Description

technical field [0001] The invention belongs to the technical field of solar heat collection, and in particular relates to a method for collecting solar heat by concentrating light. Background technique [0002] The radiant energy of about 6000 degrees Celsius on the surface of the sun radiates into space, of which about 1 / 2 billion is radiated to the earth, and the radiated energy is about 5.5×1024 joules per year. The energy consumed by human beings every year is about 5 billion tons of oil. The radiation energy from the sun to the earth is more than 20,000 times the total energy consumed by human beings, that is, the energy consumed by human beings every year is about 20 minutes of radiation energy from the sun to the earth, and the energy consumed by human beings every day is only 3 seconds of radiation from the sun to the earth Energy is enough. Such huge solar radiant energy is an ideal energy source that is inexhaustible for human beings, without mining and pollutio...
