“…At the entrance of the mixed liquid into the rotary bowl, rotary grids which make the mixture form stable fluid vortex in the rotary bowl are installed. The rotary grids will cause resistance and pressure loss by the flow of the mixture, the higher the rotational speed is, the bigger pressure loss is; the quantity of rotary grid e will directly proportional to vortex strength of the fluid, also increase the pressure loss [7]. According to The dynamic hydrocyclone structure parameters optimization design [8], three pieces rotary grids are installed in rotary bowl in order to improve the separation efficiency, easy processing, convenient installation and other elements to the common principles.…”

Treatment about bilge water is always one key point of the ship pollution prevention, at present, separation accuracy of the separator on board can reach requirements of specification for seagoing ships pollution prevention, but the separation of quantity and convenience of operation aspects are still to be improved. The ship oily water dynamic hydrocyclone separator can both meet to the above two aspects. The thinking of structure design and the manufacturing and assembly are discussed. The main structure of ship oily water dynamic hydrocyclone separator and its working principle are introduced. The basic parameters of the device working conditions are provided. The new method onboard ship oily water treatment is put forward. It can be used as references for researchers on oily water disposal.

“…Ma et al designed a ship-borne bilge water treatment system with a LLDH, whose separation efficiency was proven to be much higher than the system with static hydrocyclone. Chen et al − developed a novel LLDH for oil–water separation in deep water. The impacts of operational parameters such as flow rate, rotation speed, pressure parameters and inlet oil concentration on separation performance of that novel LLDH were studied experimentally and numerically.…”

To investigate the separation performance of a novel liquid–liquid dynamic hydrocyclone (LLDH), a series of experiments and numerical simulations were conducted. Algebraic slip mixture model was used to simulate the multiphase flow in the LLDH, in which the turbulence was modeled using Reynolds stress model and the rotation of the walls was modeled by multiple reference frame model. The numerical results showed a good agreement with the observations and measurements in experiments. The results showed that the increase of rotation speed would strengthen the swirling intensity in LLDH and thereby separation efficiency was raised. However, increase of flow rate would decrease the residence time of oil droplets, causing reduction in efficiency. By comparison, flow split ratio had slight influence on the flow field, and the efficiency rose a little as flow split ratio increased. The efficiency of the LLDH could remain high when the nondimensional rotation rate was large enough.
