Tower-disc type solar energy comprehensive utilization system

Abstract

The invention discloses a tower-disc type solar energy comprehensive utilization system, which comprises a tower, a power generation system, a solar energy receiving device and a two-dimensional solar tracking system. The power generation system is mounted at the end of the tower and utilizes sunlight received by the solar energy receiving device to generate power. The solar energy receiving device is mounted to the tower by a support and used for receiving sunlight. The two-dimensional solar tracking system is mounted on the tower and used for driving the solar energy receiving device to track the sun so as to maximize the sunlight receiving capacity of the solar energy receiving device. The tower-disc type solar energy comprehensive utilization system further comprises a gas system and a natural light illumination system, wherein the gas system is used for enabling the power generation system to work continuously when in insufficient light. Accordingly, the combined solar energy comprehensive utilization system is formed.

Description

technical field [0001] The invention relates to the technical fields of solar energy application technology, Stirling power generation power system and the like, and is a comprehensive utilization system of solar energy. In addition, a gas power system can also be installed to obtain power from solar energy and gas, which can complement each other to drive the Stirling power generation system to generate electricity. The heat generated by the Stirling power generation system heats and cools water, which can be directly used to provide domestic hot water or for cooling and heating of air-conditioning systems; the concentrated solar energy is transmitted through optical fibers and directly used for natural lighting without conversion. Background technique [0002] Solar energy has been widely used in photovoltaic power generation, tower, dish and trough solar thermal power generation, dish and trough heating systems and natural lighting.

AI Technical Summary

Problems solved by technology

The current various solar energy utilization systems cannot organically combine photothermal power generation, photothermal heating and natural lighting, and cannot achieve the greatest comprehensive utilization of solar energy with the best combination of structural forms and the most advanced component technologies. efficiency

For example, the existing tower-type solar power generation system still uses the traditional way of first heating water to generate steam, and then driving the steam turbine to generate electricity. The power generation efficiency is low, and the tracking and control of the heliostat is difficult. Only large-scale power generation systems have application value

The focus of the parabolic reflector of the existing dish solar power generation system moves in space with the movement of the sun, so the power generation system also moves in space with the focus. If a heating system is added, it is difficult for the water pipeline to move in a wide range of space , which brings difficulties to design and manufacture

The above reasons limit the application of tower and dish solar energy utilization systems, and it is difficult to develop to a deeper level of commercial operation and industrialization
