Abstract

The invention provides a solar energy and ocean temperature difference energy cascading type power generation device and a utilization method thereof. The cascading type power generation device comprises a solar energy water heater which is used for heating surface seawater, a multi-level flash tank which is connected with a high-temperature seawater outlet of the solar energy water heater, an organic Rankin power generation system which is connected with the multi-level flash tank and a deep layer cold seawater supply pump which supplies cooling water for the organic Rankin power generation system; the organic Rankin power generation system comprises an evaporator, an expansion machine which is provided with an electric generator, a condenser, an organic working medium storage tank and an organic working medium pump which are sequentially connected and form into an organic Rankin power generation system; the evaporator is connected with the multi-level flash tank. The cascading type power generation and seawater desalting device heats the surface seawater to compensate the ocean thermal energy through solar energy and generates electricity through the organic Rankin power generation technology, meanwhile prepares fresh water through condensing fresh water of the evaporator and enables various energy resources to be comprehensively utilized.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solar energy and ocean water temperature difference energy, in particular to a cascade power generation device utilizing solar energy and ocean temperature difference energy and a method for using the same. Background technique [0002] With the rapid development of the country's economy, the country's demand for energy is increasing, while our country's reserves of fossil fuels are getting less and less, and the burning of fossil fuels is deteriorating the environment. Therefore, the development of new energy has become our country's solution to the energy crisis. and an effective way to achieve sustainable development. Moreover, in my country's coastal and island areas, there are many places that are seriously short of electricity and fresh water, which seriously affects the local economic development and the improvement of people's living standards. However, the ocean is a...
