▎ 摘　　要

NOVELTY - Solar seawater desalting system comprises a linear Fresnel condensation heat collection system (4), a phase change heat storage system, and an annular humidification and dehumidification system. The linear Fresnel condensate heat collection system comprises a vacuum heat collecting pipe divided into two branches sequentially provided with a second valve (7), a first wave-shaped heat exchange pipe (29). The first valve (6), a third valve (9), middle section of the third wave-type heat exchange tube is provided with a branch sequentially connected with the second pump. The second wave heat exchange tubes and fourth valve to form an independent circulation pipeline. The first valve is connected to the inlet of the vacuum heat collection pipe through a first pump. The phase change heat accumulation system provided with heat storage tank and heat accumulation change heat accumulator. USE - The solar seawater desalting system is useful in technical field of energy optimization. ADVANTAGE - The solar seawater desalting system has simple structure, convenient operation, low operating condition requirement, and high applicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for working method of solar seawater desalting system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of solar seawater desalting system (Drawing includes non-English language text). 4Linear Fresnel condensation heat collection system 5First pump 6First valve 7Second valve 8Phase change heat storage tank 9Third valve 10Second pump 11Fourth valve 12First heat exchanger 13Wet air channel 14Nozzle 15Wet channel 16Condensing pipe 17Fresh water bucket 18Fan 19Concentrated salt water bucket 20Dry air channel 21Third pump 22Fourth pump 23Fifth pump 24Second heat exchanger 25Sea water inlet channel 26Concentrated brine outlet channel 27Fresh water outlet channel 29First wave-shaped heat exchange pipe 32Fourth wave heat exchange tube 33Heat conducting medium 34Phase change medium heat accumulation
