Flexible self-adaptive focusing solar seawater desalination system and seawater desalination method

Abstract

The invention discloses a flexible self-adaptive focusing solar seawater desalination system and a seawater desalination method, and belongs to the field of seawater desalination. The flexible self-adaptive focusing solar seawater desalination system mainly comprises a seawater pump, a heat regenerator, a condenser, a flexible convex transparent water storage cavity, a heat collector, a flash evaporation tank, a water collection tank, a solar cell panel, a vacuumizing system and the like. The flexible self-adaptive focusing solar seawater desalination system is characterized in that a convex lens is formed after containing seawater in the flexible convex transparent water storage cavity which adopts a transparent material, self-adaptive liquid level regulation is realized according to an irradiating angle of sunlight, solar is always focused on the heat collector, so that the utilization rate of the solar is increased; the flexible self-adaptive focusing solar seawater desalination system is provided with the solar cell panel, the solar is converted into electric energy for directly driving the seawater pump, so that the energy consumption of the flexible self-adaptive focusing solar seawater desalination system is reduced; during a whole seawater desalination process, the heat regenerator and the condenser are added for recycling sensible heat of concentrated seawater and potential heat of water vapor, so that efficient recycling and utilizing of energy can be realized; the flexible self-adaptive focusing solar seawater desalination system has the advantages of little energy consumption, low manufacturing cost and low maintenance cost, and is suitable for islands where are lack of electricity and underdeveloped regions.

Description

technical field [0001] The invention designs a flexible adaptive focusing solar seawater desalination system and a seawater desalination method, belonging to the field of seawater desalination. Background technique [0002] Fresh water is one of the basic substances for human survival and development. With population expansion and environmental pollution, water resource shortage has become a major problem facing human beings in the 21st century. Studies have shown that seawater desalination is the fundamental way to solve water resource shortage. Seawater desalination refers to the process of removing excess salt and minerals from water to obtain fresh water. At present, the commonly used seawater desalination technologies in industry mainly include thermal method and membrane method. The efficiency of the thermal method is low, and the initial investment cost is high, while the membrane method consumes electricity and has high maintenance costs. Both of these technologies ...
