Embodiment 2

[0040] This example has the same structure as Example 1, except that the hydrophobic porous layer is made by the following preparation method:

[0041] (1) Take the melamine resin foam, wash it with deionized water, and then dry it overnight at a low temperature of 40°C for later use;

[0042] (2) Add anionic polyacrylamide into deionized water, stir evenly, place on a magnetic stirrer and stir at room temperature for 20 hours to obtain a transparent anionic polyacrylamide solution with a concentration of 1.5% by mass;

[0043](3) Take 5-aminosalicylic acid, add it to deionized water, stir evenly, place it on a magnetic stirrer and stir at room temperature for 20 hours to obtain a transparent 5-aminosalicylic acid solution of 7 mg / ml;

[0044] (4) Take sodium carboxymethyl cellulose and nano-titanium dioxide, add them to deionized water at the same time, adjust the pH value of the solution to 7 with 1mol / L HCl, ultrasonicate the prepared mixed solution for 4 hours, and then st...

[0050] This example has the same structure as Example 1, except that the hydrophobic porous layer is made by the following preparation method:

[0051] (1) Take the melamine resin foam, wash it with deionized water, and then dry it overnight at a low temperature of 60°C for later use;

[0052] (2) Add anionic polyacrylamide into deionized water, stir evenly, place on a magnetic stirrer and stir at room temperature for 28 hours to obtain a transparent anionic polyacrylamide solution with a concentration of 0.5% by mass;

[0053] (3) Take 5-aminosalicylic acid, add it to deionized water, stir evenly, place on a magnetic stirrer and stir at room temperature for 28 hours to obtain a transparent 5-aminosalicylic acid solution of 3 mg / ml;

[0054] (4) Take sodium carboxymethyl cellulose and nano-titanium dioxide, add them to deionized water at the same time, adjust the pH value of the solution to 7 with 1mol / L HCl, ultrasonicate the prepared mixed solution for 4 hours, and then stir...

Abstract

The invention discloses a solar seawater desalination device. The device comprises a solar assembly, the solar assembly comprises a transparent or semitransparent solar cell, at least one stage of water distillation device is arranged below the solar cell, the water distillation device comprises a heat conduction layer, a water evaporation layer, a hydrophobic porous layer and a condensation layer which are sequentially arranged from top to bottom, the water evaporation layer is made of melamine resin foam, and the hydrophobic porous layer is made of hydrophobic melamine resin foam. The high photothermal conversion efficiency is achieved, the seawater desalination efficiency is greatly improved, and the seawater desalination efficiency reaches 4.1 kg / m<2> / h.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a solar seawater desalination device. Background technique [0002] The shortage of fresh water resources in the world has become a growing concern. Some people predict that in the 19th century there will be competition for coal, in the 20th century there will be competition for oil, and in the 21st century there may be competition for water. As an open-source incremental technology for water resources, seawater desalination has become an important way to solve the global water crisis. By 2006, more than 120 countries and regions in the world had applied seawater desalination technology, and the global daily output of seawater desalination was about 37.75 million tons, 80% of which was used for drinking water, solving the water supply problem of more than 100 million people. [0003] "Ask for fresh water from the ocean" has become a thriving industry. By the end ...
