Lens light-guide tower-type solar energy collection system based on spotlight heliostat array

Abstract

The invention relates to a tower type solar energy collection system, in particular to a lens light guide type tower type solar energy collection system based on a concentrating heliostat array, which mainly includes a lighting array composed of lighting module units and a solar collector responsible for solar energy collection. tower. The entire lighting array is distributed in a square matrix, and the solar collection tower is located in the center of the array. Each lighting module unit has the same structure and is composed of n*n lighting mirrors. The main difference between this system and the traditional tower solar collection system is the difference in the lighting mirror and the way of light transmission. The lighting mirror used in this system is a square dish-shaped condenser mirror. Unlike the traditional tower solar collection system that directly collects solar energy through a single reflection of the lighting mirror, this system collects the light through the lighting mirror and then passes through the lens and the reflective plane mirror for multiple transmissions before finally reaching the solar collection tower to complete the collection of solar energy.

Description

Technical field [0001] The invention relates to the field of solar energy collection, in particular to a tower-type solar energy collection system in which light is collected by a concentrating heliostat array and conducted through a lens, and finally the light is collected and collected in a solar energy collection tower. Background technique [0002] The advancement of science and technology and economic development all have a high dependence on energy. The long-term and large-scale use of traditional petrochemical energy has caused irreparable damage to the earth's environment. Moreover, with long-term large-scale exploitation and utilization, traditional petrochemical energy sources have reached the brink of resource depletion. Vigorously develop clean and efficient new energy to replace traditional petrochemical energy is our top priority. The sun is the energy source of the earth, and the use of solar energy has made great progress in recent years. [0003] At present, the...

AI Technical Summary

Problems solved by technology

The three systems have their own advantages and disadvantages, but none of them can handle the balance of solar energy collection efficiency, system manufacturing cost and large-scale construction well.

For large-scale solar energy utilization projects, no matter from the perspective of construction cost, work management, daily maintenance or system reliability, the traditional dish solar energy collection system is not competent

[0006] The traditional trough solar collection system is in the form of line focusing, and the efficiency of collecting light is low

In addition, large-scale trough systems must have very long heat collecting tubes, which will cause great energy loss

The lighting trough is too long, and the corresponding heat collecting tube is also very long, resulting in weak wind resistance of the system

[0007] To sum up, traditional solar energy collection systems have obvious problems in terms of solar energy collection efficiency, cost control, and wind resistance of the system.
