Abstract :
A new method on dehydrating mist in gas with high efficiency is presented. Mist in gas can be dehydrated by the bent plate dehydration. Based on the model of steady flow of incompressible Newtonian fluid, the difference equations of flow and pressure field of bent plate dehydration equipment are built. Numerical Solution of vorticity, stream function and pressure are also obtained. The equations are solved by using matlab Version 6.5. The results show that the pressure loss of bent plate dehydration equipment is mostly affected by its structure parameters and inlet gas velocity. To decrease the pressure loss, length of the bent plate is at 120 mm, turning angle is less than 54deg, and plate spacing is at 20~30 mm. The inlet gas velocity must be less than 6 m/s because the water film on the wall of bent plate will be ruptured when it is more than the critical velocity. It can be seen that the tendency of pressure loss is uniform from the experimental results. The numerical method on solving the pressure loss of bent plate can be used for the industrial design.
