碩士 / 國立臺灣海洋大學 / 輪機工程學系 / 103 / The experimental design of a small flash vaporization desalination machine, and to install a different wall surface roughness in a vacuum platform, to allow the water to enter from the water after heating to the inside of the vacuum platform, the aperture of 0.5 mm with special a nozzle against the wall of the vacuum, by the rough surface of the wall on the particle size of the water molecules to break up, to achieve the effect of the secondary collision, and since the surface area of the water molecules becomes smaller, you can use relatively less evaporate into steam energy to achieve the conditions, but also accelerated its upward velocity of the water condenses into desalination, and finally collecting the condensed water after desalination, to no vacuum platform with increased water desalination compared to the rough surface of the lower proved in flash increase the rough surface of the inner vaporized water desalination machine to create the effect of secondary impact, not only its create desalinated water salinity TDS water quality control indicators are in line with, and indeed can be made to effectively improve water desalination machines. Then at different temperatures down to experiment with pressure was observed after this desalination machine to increase rough surfaces at low temperatures and low pressure conditions to obtain the most effective conditions for fresh water. Data in the whole experiment under, and freshwater machine without increasing the salinity and rough surface made of water than to prove that increased roughness can effectively improve the water in the fresh water making machine, an overview of the overall experimental data found in the interior wall surface of vaporization set on the rough surface when P280, at various temperatures, pressure, level and build water desalination Jieneng effectively improved.
