Abstract

The invention discloses a solar seawater desalination system and method, and relates to the field of seawater desalination. The system comprises a seawater storage tank, a solar light gathering cover,a fresh water storage tank, a seawater spraying and exhausting device, a heat gathering and conducting device, a fresh water collecting tank, an annular condenser, a solar reflecting mirror, a freshwater spraying condenser, a solar power generation system and a solar tower type seawater concentration and crystallization system. A plurality of layers of heat gathering units such as a solar reflecting mirror, a solar light gathering cover and the heat gathering and conducting device are adopted, seawater in the solar light gathering cover is rapidly heated to form saturated steam; the seawaterspraying and exhausting device is used for increasing the evaporation speed and evaporation capacity of seawater, steam is condensed into fresh water in an omnibearing mode through multiple condensers such as a solar light gathering cover, an annular condenser and a fresh water jet condenser, the seawater evaporation capacity is increased through the solar tower type seawater concentration and crystallization system, and the desalination efficiency is improved. Solar energy is utilized, external energy is not needed, more energy is saved, and the system has the advantages of novel process, simple structure, high desalination rate, low operation cost and the like.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a solar desalination system and method. Background technique [0002] Fresh water is one of the basic materials for the survival and development of human society. At present, fresh water resources are becoming more and more scarce, and the distribution is seriously uneven. The shortage of fresh water resources in the world has become a problem of increasing concern to people, and it has also affected the economy of some countries. develop. In order to solve the crisis of fresh water resources, people began to go to the vast ocean to open up new and more abundant water sources, which is to desalinate sea water. The current mainstream desalination methods mainly include: reverse osmosis, ion exchange, distillation, freezing, adsorption, etc. All of the above methods consume a lot of fuel or electricity, and have the disadvantages of complex equipment and high energy consumptio...
