Problems solved by technology
However, the current solar photovoltaic and photothermal power generation systems still have problems of low efficiency and high cost. If solar power is used to drive the reverse osmosis seawater desalination system, the initial investment will be too large and the economic benefits will be poor.

The present invention relates to the technical field of resource recycling, in particular to a seawater desalination treatment method based on clean energy, comprising the following steps: pumping pretreated seawater into a solar preheating component through pump I for preheating treatment; The seawater is pumped into the solar desalination circulation device through the pump II for seawater desalination treatment to obtain high-temperature steam and high-temperature concentrated seawater; the high-temperature steam flows through the condensation pipe I and the condensation pipe II for condensation treatment to obtain fresh water; the high-temperature concentrated seawater is passed through the pump III Pumped into the solar preheating component, it flows through the water inlet pipe I, a plurality of serpentine heat exchange pipes and the water outlet pipe I, and after cooling down, it is transported to the salt making equipment. The clean energy-based seawater desalination treatment method provided by the present invention can effectively utilize solar thermal energy and solar electric energy to desalinate seawater, and no harmful substances are discharged during the desalination treatment, which effectively protects the environment, saves energy and reduces emissions, and finally obtains fresh water, products such as salt.
Description
technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination treatment method based on clean energy. Background technique [0002] Water resources are the material basis for the production and life of human society. The per capita freshwater consumption in my country is only 1 / 4 of the world average level, and the pressure on water resources is enormous. Especially in coastal areas, due to the developed economy, the consumption of water resources is huge. At present, more than 300 coastal cities in my country are facing water shortage problems. The shortage of water resources not only limits the development speed of the local economy and the further improvement of people's quality of life, but also causes problems such as seawater intrusion and ground subsidence caused by excessive exploitation of groundwater. Therefore, using seawater desalination technology to obtain fresh water from the ocean is ...
