Problems solved by technology

[0005] However, the current linear Fresnel reflective solar system has the following deficiencies, which affect the development and popularization of the system: 1. Due to the use of flat mirrors, the concentration ratio of the system is limited, which affects the applicable temperature and concentration of the solar collector. Thermal efficiency; 2. The heat collector is fixed in the air, which affects the stability and safety of the heat collector, which is not conducive to the layout of the pipeline and the installation of the system, and has high heat loss; 3. The light is reflected on the heat collector The angle is too large, which increases the requirements for tracking accuracy

Abstract

This patent discloses a two-level curved surface Fresnel reflective solar cavity heat collector, including a first-level reflector, a first-level reflector support ring, a second-level reflector, a second-level reflector support rod, a rotating device, a solar Heat collector; the primary reflector is composed of multiple primary reflector units, each primary reflector unit is a strip-shaped concave mirror, the primary reflector unit can rotate around the rotation axis, and the secondary reflector is composed of multiple It is composed of secondary reflector units, each secondary reflector unit is a strip-shaped convex mirror, and the solar heat collector is placed on the ground, using a cavity type heat collector. The solar heat collection device has a high concentration ratio, and the stability and wind resistance of the solar heat collector are good. At the same time, the angle of the incident beam of solar energy is small, and the combination of the cavity heat collector has higher heat collection efficiency. The structure of the device Simple, low cost, easy to install and maintain, great potential for promotion.

Description

technical field [0001] The invention relates to a solar heat collecting device, in particular to a secondary curved surface Fresnel reflective solar cavity heat collecting device, which belongs to the technical field of solar energy utilization. Background technique [0002] The commercial development and utilization of solar energy is an important development trend in the field of renewable energy. The International Energy Agency (IEA) predicts that by 2040, solar power will account for more than 20% of the world's electricity supply. Concentrating solar thermal power generation technology, as an important way of solar energy utilization, has become one of the important directions of international solar technology development. China's "Eleventh Five-Year Plan for Renewable Energy Development" also clearly stated that it is necessary to select suitable areas to develop solar thermal energy in the Ordos Highlands of Inner Mongolia along the Yellow River flat desert, Gansu Hex...
