Claims

[Scope of utility model registration request]

(1) In an oil-water separator that sends oil-containing sewage from a ship's oil-containing sewage source to an oil-water separator to separate oil and water, and then discharges the separated water overboard, an oil-containing sewage inflow pipe and a water discharge pipe are installed inside the tank body. In addition, a lower opening partition plate and an upper opening partition plate are sequentially installed between the two pipes to form a vertically winding flow path, and oil-containing wastewater is passed through this flow path to separate oil and water by specific gravity. An oil-water separator characterized in that an oil-water separation tank for collecting oil and depositing sludge at the bottom of the tank is disposed on the inlet side of the oil-water separator.

(2) The oil-water separator according to claim 1, wherein the oil-water separator is provided between a bilge tank and a bilge well arranged on the inlet side of the oil-water separator.

(3) Utility model registration claim 2, characterized in that the oil recovered in the oil-water separation tank is supplied to the incinerator together with the oil recovered in the oil-water separator via an oil bilge tank and an incinerator tank. The oil-water separator described.

(4) The oil-water separator according to claim 3, which is a utility model, and is characterized in that water separated by specific gravity in an incinerator tank is recovered in an oil-water separation tank.

(5) A pair of upper and lower level switches are installed inside the tank body of the oil-water separation tank to detect the interface between gravity-separated oil and water and operate the opening/closing valve of the oil recovery port, and an inverted U is installed on the water discharge pipe. The opening end of the inverted U-shaped section is located below the lower level switch, and the top dead center of the inverted U-shaped section is located above the upper level switch. The oil/water separator according to claim 1, 2, 3, or 4 of the utility model registration claim, characterized in that the oil recovery port is located at an intermediate position in the vertical direction with respect to the level switch position. Device.

(6) As oil-water separation progresses and the oil-water interface descends, and the upper level switch and then the lower level switch detect oil, the on-off valve opens and oil recovery begins. The oil-water interface rises and the lower level switch then the upper level switch detects moisture 1
．． At that point, the on-off valve will close and oil recovery will stop. An oil-water separator according to claim 5, which is characterized by:
