Application of water ring vacuum pump in solar sea water desalination system
Abstract:A novel simple solar sea water desalination device in negative pressure in which water ring vacuum pump was applied was proposed and its process as well as its characteristics was introduced. The influence of the working performance of water ring vacuum pump on the sea water desalination system was analyzed, and experimental study of its working performance was carried on. The dependency of the pumping capacity on the vacuum pressure which can provide theoretical foundation for matching sea water evaporation in negative pressure and vacuum pump was obtained, and it will be helpful to determine the optimal evaporation temperature of sea water and the degree of vacuum of the system.
Keywords: water ring vacuum pump solar sea water desalination degree of vacuum pumping speed experiments
