容器が必要となつた。 If waste oil that falls on the floor of off-shore oil production facilities, or rainwater containing waste oil, is disposed of directly into the sea, it may cause a pollution problem. Therefore, in the past, a sump caisson was installed at the foot of the platform of off-shore equipment to guide waste oil and rainwater containing waste oil into the caisson to prevent them from leaking into the sea. Oil and water separation was performed to recover the oil. In this oil recovery, a sump pump is installed in the sump caisson to discharge the waste oil, and as shown in FIG. is installed in the sump caisson 53, and drained oil is sent from the sump caisson 54 through the sump caisson 53.
The waste oil stored on the sea surface is guided into the blow case 52 through the check valve 51 by using the difference between the tidal level L 3 and the tidal level L 4 , and the pressurized gas is supplied from the air supply pipe 55 . There is a method of injecting waste oil into the case 52 and sending out waste oil from the oil feed pipe 56. However, in the former case, the sump pump had a special structure, and the sump caisson was installed at the foot of the platform, making inspection and repair extremely difficult in the event of pump failure. Furthermore, depending on the type of waste oil, it could even condense inside the pump and cause the pump to malfunction. Also, in the latter case,
The check valve 51 is provided at the lower end of the blow case 52, and the drained oil is introduced from here. Therefore, when the amount of drained oil accumulated in the sump caisson 53 decreases, a small amount of drained oil As a result, a large amount of seawater will be introduced into the blow case 52,
Therefore, a large-capacity container was required as a separate oil-water separator.

提供する。 In order to achieve this purpose, the present invention is designed such that a blow case 3 equipped with a check valve 4 for taking in waste oil is installed in a sump caisson 1 for collecting waste oil at or near the average high water level L3 . An oil supply pipe 7 is arranged at the bottom of the case 3, and an air supply pipe 8 is arranged at the top of the case 3.

This is done to prevent leakage. A communication port is provided at the bottom of the sump caisson 1, so that the internal oil drainage level is aligned with the external sea level. The average highest tide level (lowest high tide) is the tide level L 3 , and the average lowest tide level (lowest low tide) is the tide level L 4 .

制御器６からの信号によつて制御される。 A blow case 3 is vertically disposed within the sump caisson 1. A wafer-shaped drain oil intake check valve 4 is provided at the top of the blow case 3. The height position of the valve 4 is 200 to 250 mm lower than the average highest water level L3 . The check valve 4 only allows waste oil to flow into the blow case 3. An oil supply pipe 7 that opens at the bottom of the blow case 3 is arranged, and an air supply pipe 8 is arranged at the top of the case 3.
The drained oil in the sump caisson 1 is introduced into the blow case 3 through the check valve 4 using the tidal level difference. Next, the waste oil filled in the case 3 is sent out from the blow case 3 by the pressurized gas from the air supply pipe 8 and guided to the oil-water separation tank 9 via the oil supply pipe 7. In this way, the introduction of the waste oil into the blow case 3 and the sending of the waste oil from the blow case 3 by the pressure gas are alternately repeated, and the waste oil is sent to the separation tank 9. Pressurized air is generally used as the pumping gas, but if the waste oil is highly flammable, pressurized inert gas such as nitrogen gas or combustion exhaust gas is used.
In the oil-water separation tank 9, the waste oil is separated into oil and sea water, the oil is recovered via a pump 10, and the sea water is returned to the sump caisson via a water return pipe 11. The pump 10 is controlled by a signal from a liquid level switch 12 in the separation tank 9, and the valve 5 of the water return pipe 11 is controlled by a signal from a liquid level controller 6 installed in the oil/water separation tank 9. be done.

る。 The blow case according to this invention is as described above, and has a check valve for drain oil intake installed at the top of the case and a required distance below the average highest water level, so the check valve is submerged in the sea. The time required for this is short, so there is no risk of a large amount of seawater being introduced into the blow case along with a small amount of drained oil. Therefore, a small-capacity oil-water separator is sufficient, and a great advantage can be obtained in terms of equipment costs.
