Offshore vessels or production platforms are often provided with a kitchen and during cooking and cleaning of the food produce waste water, known as kitchen oily grey water, which typically contains grease. In order to avoid environmental pollution, the oily grey water is discharged to a domestic sewage treatment device through a pipeline for treatment, but the grease contained in the oily grey water is not easy to degrade by the domestic sewage treatment device, and the problems of pipeline blockage and the like are also easy to cause. Therefore, an oil skimmer is generally disposed on the oily grey water discharge line for removing grease and scum.

At present, a three-cavity oil skimmer is mostly adopted at sea for oil-water separation, a baffle plate arranged in the oil skimmer enables oily sewage to flow in the oil skimmer in a baffling mode, oil and water are layered up and down in a middle cavity due to different specific gravity, oil drops float on the oil drops and are separated from water, and then the oil in the oil skimmer is discharged through an oil outlet, but the oil skimmer is difficult to discharge floating oil and scum through condensation and saponification after the oil skimmer operates for a period of time, so that the oil outlet is blocked. In order to solve the above problems, chinese patent application No. 201811050354.1 provides an oil skimmer, which includes (abstract), and although this patent solves the problem of pipeline blockage due to floating oil or scum condensation, during operation, because the water flow is large and the flow rate is fast, the oil droplets will not float up in the oil-water separation chamber for a long time, and some oil droplets will be carried to the clean water chamber, and the oil-water separation is not obvious. In addition, the patent also fails to open the tank to clean the inside of the skimmer.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the drawings.

The utility model discloses an oil skimmer for processing kitchen waste of an offshore oil production platform, which comprises a box body, wherein a water inlet 1 is arranged on the left side wall of the box body, a water outlet 2 is arranged on the right side wall of the box body, the lower edges of the water inlet and the water outlet are aligned, and the lower edges of the water inlet and the water outlet are on the same horizontal line; a first baffle 13 is arranged on the left side in the box body, a second baffle 14 is arranged on the right side in the box body, the upper ends of the first baffle 13 and the second baffle 14 are connected with the top of the box body, and a through hole is formed in the surface of the first baffle 13; the through hole is a circular hole through which oil-containing grey water can pass; the first baffle 13 and the second baffle 14 divide the interior of the box body into three chambers, namely a first chamber 15 at the left side, a second chamber 16 at the middle part and a third chamber 17 at the right side; the lower end of the second baffle plate 14 is lower than the lower end of the first baffle plate 13, and a gap is formed between the lower end of the second baffle plate 14 and the bottom wall of the box body, so that the first chamber 15, the second chamber 16 and the third chamber 17 form a chamber with communicated lower parts; a bulge 18 is arranged on the inner wall of the second chamber 16, and the position of the bulge 18 is lower than the lower edge of the water inlet 1; the oil skimmer further comprises a floating oil collector 6, wherein the upper edge of the floating oil collector 6 is placed on the bulge 18, and the bottom of the floating oil collector is provided with an oil discharge port 12 for discharging floating oil and oil residue out of the oil skimmer.

Preferably, the body of the oil slick collector 6 is funnel-shaped.

Preferably, the upper edge of the floating oil collector 6 is provided with oil inlet holes, the bulges are point-shaped bulges, the number of the bulges is more than or equal to 6, and the bulges are scattered on the inner wall of the second chamber.

Preferably, a window 5 is arranged on the front of the tank body and used for observing the level of the floating oil in the floating oil collector 6.

Preferably, the top of the tank also comprises an exhaust port 4, an access cover plate 3, said access cover plate 13 being openable for cleaning the inside of the skimmer tank.

Preferably, the middle lower part of the box body is also provided with an electric heater 7, an electric cabinet 8, and a temperature controller is arranged in the electric cabinet 8; the lower part of the electric heater 7 is also provided with a temperature sensor 10; the bottom of the box body is provided with a discharge port 11 and a grounding post 9.

As shown in figure 1, in actual operation, when the oil skimmer is used for the first time, clear water is added through the water inlet 1, so that the oil skimmer box body contains partial clear water, and the clear water at least overflows the lowest end of the second baffle plate 14. When the oily grey water in the kitchen enters the box body of the oil skimmer through the water inlet 1 of the oil skimmer, due to the water inflow and the flow rate, the oily grey water impacts the first baffle 13, part of the oily grey water enters the second chamber 16 through the holes of the first baffle 13, part of the oily grey water flows back to the first chamber 15 through the first baffle 13, and the rest of the oily grey water impacts the second baffle 14 and flows back to the second chamber 16. Because the densities of water and oil are different, after standing for a period of time, the water and the oil form upper and lower layers, the floating oil is concentrated in the first chamber 15 and the second chamber 16, when the floating oil submerges the upper edge of the floating oil collector 6, the floating oil automatically flows into the floating oil collector 6 through an oil inlet hole at the upper edge of the floating oil collector 6 and is discharged through an oil outlet 12, and the sewage containing the oil and the water in the kitchen enters a domestic sewage treatment device through a water outlet 2 for treatment so as to reach the standard of reclaimed water recycling.

A temperature controller is arranged in the electric cabinet 8; a temperature sensor 10 is arranged at the lower part of the electric heater 7; when the ambient temperature is reduced, namely the temperature in summer is lower than 25 ℃ and the temperature in winter is lower than 23 ℃, the temperature controller starts the electric heater 7 according to the output signal of the temperature sensor 10, so that the required temperature is kept in the oil skimmer box body, and the oil discharge port 12 is prevented from being blocked due to the condensation and saponification of the floating oil.
