Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and more specifically to an installation system for an air compressor on an oil tanker. Background Technology

[0002] The installation of air lubrication systems on oil tankers is challenging because regulations require that the deck height of 2.4 meters on oil tankers constitute a Class II hazardous area. The air compressor for this system cannot be placed in a hazardous area. Air lubrication systems can save ship owners 8% on fuel during voyages, making them very popular. Some oil tankers have their air compressors installed in the bosun's quarters, but this results in long air pipes, depressurization, and increased energy consumption.

[0003] Therefore, the inventors have provided an installation system for an air compressor for an oil tanker. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] This invention provides an installation system for an air compressor on an oil tanker, solving the technical problem of difficult layout of air compressors on oil tankers.

[0006] (2) Technical solution

[0007] This invention provides an installation system for an air compressor on an oil tanker, comprising an air compressor room, an overpressure area, and an air compressor placed in the air compressor room. The air compressor room is located at the bow deck of the ship. The overpressure area is an enclosed space surrounded by a door to the air compressor room. The air pressure inside the air compressor room is greater than that in the overpressure area, and the air pressure in the overpressure area is greater than that in the external environment.

[0008] Furthermore, an exhaust fan is installed on the top of the air compressor room.

[0009] Furthermore, corresponding air inlets are provided on the side walls of both the air compressor room and the overpressure area.

[0010] Furthermore, the distance between the height of the air inlet and the deck is greater than 2.4m.

[0011] Furthermore, the air inlet includes a housing, an air inlet, an air outlet, a filter cotton, and an exhaust blade. The air inlet and the air outlet are respectively connected to opposite sides of the housing. The filter cotton and the exhaust blade are installed in the inner cavity of the housing, and the filter cotton is located at the air inlet.

[0012] Furthermore, the air inlet also includes a backflow prevention rubber sheet, which is installed in the inner cavity of the housing and located at the air outlet.

[0013] Furthermore, the air inlet also includes a storage box, which is installed in the inner cavity of the housing and located below the filter cotton.

[0014] Furthermore, the exhaust fan has the same structure as the air inlet fan.

[0015] Furthermore, there is a set vertical distance between the air compressor room and the bow deck of the ship.

[0016] Furthermore, the air compressor room is located between the #88 and #90 ribs of the hull.

[0017] (3) Beneficial effects

[0018] In summary, this invention, by locating the air compressor room on the bow deck of the ship, closer to the air outlet of the air lubrication system, ensures a safe environment for users entering the overpressured area from the hazardous area. Because the pressure in the overpressured area is higher than the external environment, hazardous gases will not enter. Furthermore, to prevent contamination of clothing, users can enter the air compressor room from the overpressured area for a second purging, thus guaranteeing the safety of the air compressor room. This installation system allows for efficient air compressor placement on oil tankers, reducing installation costs. Attached Figure Description

[0027] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention. That is, the present invention is not limited to the described embodiments, and any modifications, substitutions and improvements to the parts, components and connection methods are covered without departing from the spirit of the present invention.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Figure 1 This is a schematic diagram of the installation system of an air compressor for an oil tanker provided in an embodiment of the present invention. See also: Figure 1-4 The installation system may include an air compressor room 1, an overpressure area 2, and an air compressor 3 placed in the air compressor room 1. The air compressor room 1 is located at the bow deck of the hull 100. The overpressure area 2 is an enclosed space and is enclosed by a door to the air compressor room 1. The air pressure in the air compressor room 1 is greater than that in the overpressure area 2, and the air pressure in the overpressure area 2 is greater than that in the external environment.

[0032] In the above embodiment, when a user enters the overpressure area 2 from the dangerous area, because the pressure of the overpressure area 2 is greater than that of the external environment, the dangerous gas will not enter the overpressure area 2. If there is concern that the user's clothes may be contaminated, the user can enter the air compressor room 1 from the overpressure area 2 and purge again to ensure the safety of the air compressor room 1.

[0033] To save costs, this invention features an elevated layout. The floor and walls of the air compressor room 1 are reinforced (ribs, T-shaped profiles) to facilitate the placement of the air compressor 3 and the walking structure facing the deck. Therefore, at least 1m of elevation is required for construction. The interior height of the air compressor room 1 is required to be 3m. Placing it between ribs #90 and #92 would not meet the driver's line of sight requirements in the Solas specification. One side of the room needs to be against the strong structure (the entire rib position is the strong structure). Therefore, the air compressor room 1 is placed between #88 and #90, with one side against #89.

[0034] Specifically, such as Figure 4 As shown, an exhaust fan 4 is installed on the top of the air compressor room 1. Corresponding air inlets 5 are installed on the side walls of both the air compressor room 1 and the overpressure area 2.

[0035] Furthermore, there is a set vertical distance between the air compressor room 1 and the bow deck of the hull 100, specifically, the distance between the height of the air inlet 5 and the deck is greater than 2.4m. The air compressor room 1 must be a safe space, either by being elevated or by having an isolated empty compartment between it and the cargo oil tanks (the regulations stipulate that the cargo oil tanks are Class 0 hazardous areas, adjacent empty ballast water tanks separated by rigid walls are Class 1 hazardous areas, and the open deck area would create a Class 2 hazardous area with a height of 2.4m; Class 1 and Class 2 hazardous areas can be isolated by rigid walls).

[0036] As an optional implementation method, see [link to implementation details]. Figure 5 The air inlet 5 includes a housing 501, an air inlet 502, an air outlet 503, a filter cotton 504, and an exhaust blade 505. The air inlet 502 and the air outlet 503 are respectively connected to opposite sides of the housing 501. The filter cotton 503 and the exhaust blade 504 are installed in the inner cavity of the housing 501. The filter cotton 504 is located at the position of the air inlet 502.

[0037] See Figure 5 The air inlet 5 also includes a backflow preventer rubber sheet 506, which is installed inside the housing 501 and located at the air outlet 503. The air inlet 5 also includes a storage box 507, which is installed inside the housing 501 and located below the filter cotton 503. When air intake is needed during rain, rainwater is filtered through the filter cotton 504 and falls into the storage box 507, preventing rainwater from entering the air compressor room 1.

[0038] As an optional implementation method, see [link to implementation details]. Figure 1 and Figure 3 The air compressor room 1 is located between ribs #88 and #90 of the hull 100. The hull air outlet of the air lubrication system is between ribs #90 and #92. To save on pipes and bends (bends will reduce pressure), it is best to arrange the room between ribs #90 and #92.

[0039] It should be noted that the various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. The present invention is not limited to the specific steps and structures described above and shown in the figures. Furthermore, for the sake of brevity, detailed descriptions of known methods and techniques are omitted here.

[0040] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art without departing from the scope of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
