  An oil / water mixture is introduced into a rotating body and used as a centrifuge for separating oil and water components by a centrifugal separation method.

  First, the structure of the centrifuge of Example 1 is demonstrated according to FIGS. 1-3.

  The centrifugal separator (1) of Example 1 introduces a mixed liquid separation unit (10) that separates an oil / water mixture into an oil component having a low specific gravity and a water component having a high specific gravity by centrifugal force, and an oil / water mixture.

  Although the perforated adjustment cover plate (1021a) plays a role of the relative adjustment mechanism, since it is a relative adjustment, the upper cover is not equipped with the perforated adjustment cover plate (1021a). It can be carried by a hole provided at or near the center of the perforated cover plate mounted on the upper part of the plate (1021b) or the lower cover plate (1021c), and the rotating body (1021) It can also be carried by a hole provided at or near the center of the perforated bottom surface (1021e).

  The hole shape and size of the perforated adjustment cover plate (1021a) is a circular shape having an inner diameter of φ158, but can be appropriately changed in design according to the type of the mixed solution. This is because the specific gravity difference between the light liquid and the heavy liquid varies depending on the type of the mixed liquid.

  In practice, a plurality of perforated adjustment cover plates having an inner diameter of φ120 to φ170 are prepared, and are replaced with a more suitable perforation adjustment cover plate according to the type of the mixed solution.

In addition, the design can be changed as appropriate depending on the kinematic viscosity of the mixed solution, the kind of the mixed solution, and the like.

  The heavy liquid outlet (40) passes through the inner peripheral surface of the rotating body (1021), passes through the gap between the lower surface of the upper lid plate (1021b) and the upper surface of the lower lid plate (1021c), and Via the long hole provided in the radial direction from the vicinity of the vertical axis position of the upper lid plate (1021b), via the gap between the lower surface of the perforated adjustment lid plate (1021a) and the upper surface of the lower lid plate (1021c) A heavy liquid flow path (403r) reaching the upper surface of the perforated adjustment lid plate (1021a), a heavy liquid storage chamber (404r) communicating with the heavy liquid flow path (403r), and the heavy liquid storage chamber (404r) and a heavy liquid discharge pipe (405).
