Abstract

The invention relates to the technical field of solar optothermal, in particular to a solar system and method for solar heat collection and storage. The system comprises a light condensation light collection system and a heat storage circulation system; the light condensation light collection system comprises a tower frame, multiple light condensation reflection heliostat and multiple plane reflecting mirror, and the heat storage circulation system comprises a driving device, a heat collection heat exchanger, a normal temperature working medium storage device, a high temperature working mediumstorage device and heat storage working media. A constant temperature heat source is generated through solar heat collection, a stable controllable heat energy supply is provided outwards, and the beneficial effects of being adjustable and controllable in temperature, stable in output, high in optothermal efficiency and convenient to apply are achieved.

Description

technical field [0001] The invention relates to the field of solar photothermal technology, in particular to a solar system and method for collecting and storing solar heat. Background technique [0002] After decades of development, my country's solar thermal utilization industry has made remarkable achievements and formed a positive, orderly and sustainable development trend. Unlike photovoltaics, the development of solar thermal has few halos and few ups and downs, and some are just solid steps. After nearly 10 years of rapid development, the annual output value of solar heat has reached 100 billion yuan, the annual output of solar collectors has exceeded 42 million square meters, accounting for more than 70% of the world's total, and the installed capacity of solar energy has reached 145 million square meters rice, accounting for more than 80% of the world. At the same time, 95% of the production capacity of solar thermal energy is digested domestically, and the contri...
