Renewable energy generation and fresh water production integrated system for isolated island

Abstract

The invention discloses a renewable energy generation and fresh water production integrated system for an isolated island. The renewable energy generation and fresh water production integrated system comprises solar cell panels, a wind driven generator, a seawater electrolytic tank, an oxygen storage tank, a hydrogen storage tank, an alkali filtering tank, a hydrogen combustion chamber, a seawater heating furnace, a turbine, a main shaft, a generator, a user, a heat exchanger, a pipeline, a small heat exchange pipe, pumps, a coastline, a condenser pipe and a water storage tank; electricity generation is carried out by utilizing randomly fluctuated solar energy and wind energy; hydrogen is generated by electrolyzing seawater, so that energy storage is realized; combustion is carried out by utilizing hydrogen; seawater is heated to generate superheated steam, so that the turbine is driven to rotate; then, the generator is driven to output the steady power; tail gas after hydrogen combustion and water vapour discharged by the turbine are introduced into seawater for condensation through the condenser pipe, so that fresh water is generated; seawater desalination is realized; energy is effectively utilized in a diversified manner; the problem that power and fresh water are stably supplied when the isolated island is offline can be solved; the heat exchanger heats seawater by utilizing waste water vapour; therefore, utilization of waste heat is realized; and the energy utilization efficiency is increased.

Description

technical field [0001] The present invention relates to an integrated system of renewable energy power generation and fresh water production on an isolated island, specifically involving the use of randomly fluctuating solar energy and wind energy for power generation, the generation of hydrogen energy storage through electrolysis of seawater, and the use of hydrogen combustion for power generation to achieve controllability of output power. An all-in-one system that produces fresh water at the same time. Background technique [0002] With the progress of society and the development of economy, human beings have an increasing demand for energy, but the development of conventional energy has gradually been difficult to meet the demand, and the extensive use of traditional fossil energy will lead to environmental pollution. At the same time, with the development of the national marine development strategy, the shortage of energy and fresh water in isolated island off-grid area...
