Solar medium/low-temperature power generation system and power generation method

Abstract

The invention discloses a solar medium / low-temperature power generation system and a power generation method. The solar medium / low-temperature power generation system comprises a medium / low-temperature collector; a heat storage device is arranged on the medium / low-temperature collector; a condenser and an organic working medium steam turbine are mounted on the heat storage device; the condenser is connected with the heat storage device through arranging a water pump; a low-loss heat storage technology is adopted; as the heat storage quantity of the system is high, continuous power generation around the clock is realized, and the requirements on the heat storage device are stricter; and at present, the technology adopts a traditional solar water heater heat wall locking technology. An efficient heat collecting technology is adopted; and the system adopts an all-effect microwave heat collecting technology of a traditional vacuum tube solar water heater to realize efficient photothermal absorption so as to improve overall efficiency.

Description

technical field [0001] The invention relates to the field of solar photothermal medium and low temperature power generation, in particular to a solar medium and low temperature power generation system and a power generation method. Background technique [0002] Solar energy is the energy with the second fastest development speed in today's renewable energy, and it is also the focus of various countries' competing development. The solar thermal utilization, especially the solar water heating system, has taken the lead in development because of its low cost, convenient use, safety and reliability. In recent years, with the continuous decline of solar cell prices and the development of photovoltaic system technology, the world's photovoltaic market has developed rapidly. The average growth rate of the photovoltaic industry in the last ten years is 22%, and the average growth rate in the last five years is 35%, especially in 2001. In 2002 and after 2002, the annual growth rate ...

Problems solved by technology

[0003] Due to the rapid development of the photovoltaic industry, domestic photovoltaic product manufacturers have greatly expanded their production capacity, and many investment companies have transformed into the photovoltaic industry, resulting in a serious overcapacity in my country's photovoltaic industry. Finally, anti-dumping investigations against my country's photovoltaics were launched abroad, which led to domestic Many photovoltaic companies have gone bankrupt, which has led to the survival crisis of traditional solar thermal enterprises. Therefore, many governments have to intervene and rescue the photovoltaic industry, resulting in economic turmoil and unequal distribution of government resources, as well as investment and support in other industries. Reduced strength;

[0004] Destroying the traditional photothermal industry, due to the limited space of urban buildings, ordinary households have no space to install photothermal systems after installing photovoltaic systems, resulting in people's daily washing and washing relying on secondary conversion of electric energy or gas, which greatly reduces energy use efficiency and crowd out the living space of photothermal products
