The automatic dust separator is a device installed in the suction tank of the pumping or drainage plant, and prevents foreign substances such as aquatic plants or wood chips from being sucked into the underwater pump. Since the dust separator obstructs the flow of water for separating dusts, a water level difference is likely to occur before and after the dust separator. Since the water level difference before and after the dust separator acts as an additional hydraulic load on the dust separator structure, it may reduce the lifetime of the dust separator and cause damage. In this study, in order to reduce the water level difference, we devised changing the existing I-beam-shaped dust separator parts to a streamlined shape, and quantitatively analyzed the water level difference before and after the dust separator, hydraulic load, and flow velocity distribution through computational fluid analysis to confirm the effect of design improvement.
