Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to the structure of a marine oil separator's sludge tank and the ship itself. Background Technology

[0002] like Figure 1 As shown, the conventional oil separator sludge tank on a ship is located directly below the deck 100 where the oil separator 300 is located. The oil separator module consists of several oil separators 300 assembled together by a checkered plate frame. The module does not include the sludge tank. Such an oil separator 300 requires a large number of checkered plate frames 200, necessitating a significant amount of material. Furthermore, the modules composed of checkered plate frames 200 have a relatively large span, making them prone to deformation during hoisting from the workshop to the section assembly process. The medium in the oil separator sludge tank mainly consists of three parts: oil, water, and oil sludge, with water having the highest content. The conventional treatment for the medium in the oil separator sludge tank is to transport it to an incinerator for combustion. However, when the moisture content of the medium is too high, the incinerator cannot operate normally.

[0003] Therefore, a marine oil separator sludge tank structure and a vessel are needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a marine oil separator sludge tank structure and a ship, which can reduce the use of materials and ensure the normal operation of the incinerator.

[0008] A partition is fixedly installed vertically in the hollow cavity to divide the hollow cavity into an oil residue storage compartment and an oil compartment. An overflow hole is provided at the upper end of the partition, and the oil residue storage compartment and the oil compartment are connected through the overflow hole.

[0009] An oil drain line is connected to the oil tank and is used to drain oil from the oil tank.

[0010] A drainage pipe is connected to the oil residue storage tank and is used to drain water from the oil residue storage tank.

[0012] Furthermore, the oil drain line includes a first suction pipe connected to the oil tank, a first control valve is provided on the first suction pipe, and the first suction pipe is connected to a first suction pump.

[0013] Furthermore, a level switch is provided in the oil tank. The level switch is electrically connected to the first control valve and the first suction pump. The level switch has a first level alarm value and a second level alarm value. The first level alarm value is located above the second level alarm value, and the height of the first level alarm value is lower than the overflow hole.

[0014] Furthermore, the drainage pipeline includes a second suction pipe connected to the oil residue storage tank, the second suction pipe is equipped with a second control valve, and the second suction pipe is connected to a second suction pump.

[0015] Furthermore, a depth sounding tube is installed in the oil residue storage tank, which is used to measure the water level in the oil residue storage tank.

[0016] Furthermore, the oil sludge discharge pipeline includes a third suction pipe connected to the oil sludge storage tank, a third control valve is provided on the third suction pipe, and the third suction pipe is connected to a third suction pump.

[0017] Furthermore, it also includes heating pipes arranged in the oil residue storage compartment.

[0018] Furthermore, it also includes a flushing pipeline, which is arranged in the oil residue storage tank and is capable of spraying steam to flush the inner wall of the oil residue tank body.

[0019] Furthermore, a first manhole and a second manhole are provided at the upper end of the oil sludge tank body. The first manhole is connected to the oil sludge storage tank, and the second manhole is connected to the oil tank.

[0020] A vessel, comprising a hull and a marine oil separator sludge tank structure as described above, the marine oil separator sludge tank structure being disposed on the hull.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a marine oil separator sludge tank structure. The sludge tank body is mounted on the deck surface and supports the oil separator. A partition is installed in the hollow cavity of the sludge tank body, dividing the cavity into an oil sludge storage tank and an oil tank.

An oil drain pipe is connected to the oil tank to drain oil from it; a drainage pipe is connected to the oil sludge storage tank to drain water from it; and an oil sludge discharge pipe is connected to the bottom of the oil sludge storage tank to drain oil sludge from it. By installing the partition and providing the overflow hole, oil, being lighter than water, floats on the water surface and then enters the oil tank through the overflow hole, achieving oil-water separation. This results in oil with less water content entering the oil tank, sufficient for normal combustion in the incinerator. By supporting the oil separator directly on the oil residue tank body, the use of patterned plate frames is avoided, thus reducing the amount of material used. Attached Figure Description

[0032] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0033] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0035] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0036] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0037] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0038] When designing the oil sludge tank structure of a marine oil separator, in order to reduce material usage while ensuring the normal operation of the incinerator, such as... Figures 2-6 As shown, the present invention provides a marine oil separator sludge tank structure. The marine oil separator sludge tank structure includes an oil sludge tank body 1, a partition, an oil discharge pipeline 2, a drainage pipe 301, and an oil sludge discharge pipeline 4.

[0039] The oil sludge tank body 1 is mounted on the deck 100 and supports the oil separator 300. The oil sludge tank body 1 has a hollow cavity. A partition is fixedly installed vertically within the hollow cavity, dividing it into an oil sludge storage tank 11 and an oil tank 12. An overflow hole is provided at the upper end of the partition, and the oil sludge storage tank 11 and the oil tank 12 are connected through the overflow hole. The sludge discharge pipe 302 and the drain pipe 301 of the oil separator 300 extend into the oil sludge storage tank 11, with the drain pipe 301 extending to the bottom of the oil sludge storage tank 11, allowing the water in the oil sludge storage tank 11 to seal the opening of the drain pipe 301. The oil discharge pipe 2 is connected to the oil tank 12 and is used to discharge oil from the oil tank 12. The drain pipe 301 is connected to the oil sludge storage tank 11 and is used to discharge water from the oil sludge storage tank 11. The oil residue discharge pipeline 4 is connected to the bottom of the oil residue storage tank 11 and is used to discharge the oil residue in the oil residue storage tank 11.

[0040] By installing baffles with overflow holes, oil, being lighter than water, floats on the surface and flows into oil tank 12 through the overflow holes, achieving oil-water separation. This results in oil with less water content entering oil tank 12, sufficient for normal combustion in the incinerator. Since the oil separator 300 is directly supported on the oil residue tank body 1, the use of the checkered plate frame 200 is avoided, reducing material usage. Furthermore, the oil residue tank body 1 and the oil separator 300 can be combined during the on-site fabrication stage, and the entire module can be hoisted onto the hull structure, reducing workload on sections, lowering construction intensity, and preventing excessive deformation during module hoisting.

[0041] Furthermore, the oil discharge pipeline 2 includes a first suction pipe 21 connected to the oil tank 12. A first control valve is installed on the first suction pipe 21, which is also connected to a first suction pump. When it is necessary to discharge oil from the oil tank 12, the first control valve is first opened, and then the first suction pump is started. The oil is drawn out by the first suction pump and transferred to the incinerator for combustion. After the suction is complete, the first control valve and the first suction pump are closed.

[0042] Furthermore, a level switch 122 is installed in the oil tank 12, and the level switch 122 is electrically connected to the first control valve and the first suction pump. The level switch 122 can detect the oil level in the oil tank 12, thereby controlling the opening or closing of the first control valve and the first suction pump to achieve automated control.

[0043] Furthermore, the level switch 122 has a first level alarm value and a second level alarm value. The first level alarm value is located above the second level alarm value, and its height is lower than the overflow orifice. Specifically, the first level alarm value corresponds to a high-level alarm in the oil tank 12, and the second level alarm value corresponds to a low-level alarm in the oil tank 12. When the oil level in the oil chamber rises to the first level alarm value, triggering the high-level alarm, the first control valve and the first suction pump can be opened to transport the oil in the oil tank 12 to the incinerator for combustion. Because the oil in the oil tank 12 has a low water content, the incinerator can burn normally. When the oil level drops to the second level alarm value, the first control valve and the first suction pump are closed. Moreover, because the first level alarm value is set at a height lower than the overflow orifice, backflow of oil in the oil tank 12 can be prevented.

[0044] Furthermore, the drain pipe 301 includes a second suction pipe 31 connected to the oil sludge storage tank 11. A second control valve is installed on the second suction pipe 31, which is also connected to a second suction pump. When oil is discharged, the water level in the oil sludge storage tank 11 will also be high. At this time, the second control valve and the second suction pump can be opened to drain the water into the sewage well or the bilge water clarification tank. To prevent the oil sludge in the oil sludge storage tank 11 from being discharged into the sewage well or the bilge water clarification tank, the second suction pipe 31 cannot be located at the very bottom of the oil sludge tank body 1; it needs to be kept at a certain distance from the bottom.

[0045] Furthermore, a depth sounding tube 112 is installed in the oil residue storage tank 11, which is used to measure the water level in the oil residue storage tank 11. By installing the depth sounding tube 112, the water level in the oil residue storage tank 11 can be measured.

[0046] Furthermore, the oil sludge discharge pipeline 4 includes a third suction pipe 41 connected to the oil sludge storage chamber 11. A third control valve is installed on the third suction pipe 41, and the third suction pipe 41 is connected to a third suction pump. Since oil sludge is relatively heavy and tends to settle at the bottom of the oil sludge storage chamber 11, the third suction pipe 41 is located at the lower end of the oil sludge chamber body 1, enabling the discharge of oil sludge to the incinerator for combustion.

[0047] Furthermore, the marine oil separator's sludge tank structure also includes a heating pipe 13, which is arranged in the sludge storage tank 11. By installing the heating pipe 13, the liquid in the sludge storage tank 11 can be heated, thereby accelerating oil-water separation and improving the separation efficiency. Specifically, the heating pipe 13 can be electrically heated or heated using the ship's boiler; no further restrictions are imposed here.

[0048] Furthermore, the marine oil separator's sludge tank structure also includes a purging pipeline 14, which is arranged in the sludge storage tank 11. The purging pipeline 14 can spray steam to purge the inner wall of the sludge tank body 1. Specifically, the purging pipeline 14 is coiled in the sludge tank body 1, with several small holes arranged at intervals along it. The purging pipeline 14 is connected to the ship's boiler, enabling the use of high-temperature, high-pressure steam to purge the wall of the sludge tank body 1, thereby ensuring the rapid cleaning of the oil sludge or oil adhering to the sludge tank body 1.

[0049] Furthermore, a first manhole 111 and a second manhole 121 are provided at the upper end of the oil sludge tank body 1. The first manhole 111 is connected to the oil sludge storage tank 11, and the second manhole 121 is connected to the oil tank 12. By providing the first manhole 111 and the second manhole 121, it is convenient for construction personnel to enter the interior of the oil sludge tank body 1 to carry out construction work, such as painting, maintenance and cleaning.

[0050] This embodiment also provides a vessel, including a hull and the marine oil separator sludge tank structure described above. The marine oil separator sludge tank structure is mounted on the hull, which reduces material usage and ensures the normal operation of the incinerator.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
