A Method for Distillation Using the Ultrasonic Water Mist Generator

In this study, we used an ultrasonic water mist generator to efficiently generate fine saltwater mist and used dense metallic meshes to evaporate it through conduction and convection heating. This method is similar to traditional saltwater distillation, but we greatly reduce the heat source required to generate water vapor in the first stage and can quickly evaporate it on the metallic meshes to produce pure water. In addition, we performed extremely complex simulations of the evaporation process of water droplets. The simulation takes into account the change in water droplet temperature, the change in water droplet mass, the position where the water droplet rises, and the heat conduction model of the water droplet. The simulation results show that the generated water droplet can evaporate quickly after 0.46 seconds. The dense metallic meshes can efficiently carry out the heat conduction process, and the hot air layer nearby also benefits to transfer convective heat to the water droplet. We can see how the droplet size changes between 0 seconds and 0.46 seconds. In summary, this research work can be applied to real seawater desalination.
