This study proposes a new type of hydrocyclone. Through the testing of a simulation and experiment, if the overflow section at the hydrocyclone is changed to a tubular membrane, the fluid near the overflow pipe will be allowed to pass through and particles will be filtered out. Therefore, the turbulence surrounding the overflow exit can be weakened. The flow of the overflow can be increased, and its clarity can be raised. This is extremely valuable for the recycling of precious liquids and it can otherwise serve as a grading hydrocyclone. Complex flow field inside the hydrocyclone and hydrodynamic study is done with the help of commercial Fluent software. The pressure and the axial velocity decreases form the hydrocyclone wall towards the center.
