The waste heat energy of diesel exhaust of current small and medium-sized ships is a big waste, while the distillation method in marine desalination is energy-intensive and its equipment is large, as well as the reverse osmosis method is seriously polluting. In order to solve the above problems, a waste heat desalination device for small and medium-sized ships is designed based on the cold-heat separation effect of vortex tube. In this paper, based on the study of the vortex tube working principle, the parameters of the vortex tube are designed and calculated, and the optimum inlet temperature at a certain pressure is calculated to further determine the design parameters of the whole device. According to the basic laws of thermodynamics, a mathematical model is established to describe the changes in the state of diesel exhaust.
