An object of the present invention is to provide an oil-water separator with self-priming pump of high oil-water separation ability that enables a mixed liquid to be introduced into the oil-water separator without causing emulsification. The present invention provides an arrangement where
a separator portion that separates a mixed liquid includes a rough separation portion performing rough separation of the mixed liquid by cyclone separation,
a main separation portion connected to a downstream side of the rough separation portion and performing main separation according to specific gravity difference of the mixed liquid that has undergone the rough separation,
a water discharge portion connected to a lower portion of the main separation portion and discharging the water from which oil has been separated and removed, and
an oil storage tank storing the oil separated from the water and overflowing from an upper portion of the main separation portion,
a pump device portion that introduces the mixed liquid into the separator portion
includes a self-priming liquid pump connected to a downstream side of the separator portion and connected to the water discharge portion to suck the mixed liquid from an exterior of the separator portion via the rough separation portion, the main separation portion, and the water discharge portion, and
an upper portion of the rough separation portion, a portion above the main separation portion, and an upper portion of the water discharge portion are put in communication in a manner enabling venting and air that has entered into the separator portion is sucked and discharged by the self-priming liquid pump. |
