The Experiment Study on How Medium Gas Affects Seawater Desalination Facility's Performance

Abstract:

A self-designed small size three-effect tubular still is used to conduct a study on the stills performance in the condition of different medium gases (air, oxygen, carbon dioxide and helium, namely a research about the steady state water-yielding capacity and heat preservation performance. The research concludes that when using carbon dioxide as the medium gas, the steady state water-yielding capacity of desalination facility is better at temperature of 80°and below, water-yielding rate can be as much as 0.6kg/h, which is increased by 18% compared of using air as medium gas; when using carbon dioxide as the medium gas, the heat preservation performance of desalination facility is better ,of which the average temperature is 2°higher than any other medium gas. Thus the system can perform better under the condition of medium gas of carbon dioxide without illumination.
