| Abstract: | Simulation experiment on a mist separator was carried out.The aim was to determine the separation efficiency and to precisely control droplet concentration and size.Brine-air was used as experimental media of the system.Mist separation efficiency was quantitatively determined by electrochemically measuring concentration variation of Cl - ion during process.As a prominent feature,this system could avoid effects of ambient atmospheric temperature and moisture on separation and thus provided a reliable way for the study of gas-liquid separation.Key effects of droplet concentration and droplet size on mist separation efficiency and measure of control was determined.A mathematical model for controlling droplet size during mist forming by a dual-flow nozzle was set up. |
