Description

Technical Field

[0001] This invention relates to the field of marine technology, and more particularly to the installation structure of desulfurization systems and ships. Background Technology

[0002] Unlike gasoline and diesel used in automobiles, marine fuel oil used by ocean-going vessels and large coastal ships is residual oil, also known as heavy oil, which is the residue left after refining gasoline and diesel from crude oil. This type of oil is cheaper than gasoline and diesel, but due to its quality, it produces more pollutants such as sulfur oxides, nitrogen oxides, and particulate matter after combustion. According to the sulfur emission limits set by the International Maritime Organization, ships are required to use low-sulfur fuel oil with a sulfur content of no more than 0.5% or to use alternative fuels to reduce sulfur emissions. With rising oil prices, using low-sulfur fuel oil significantly increases shipowners' operating costs; therefore, many ships are installing scrubbers to reduce sulfur emissions.

[0003] The desulfurization tower is large in size, which will have a significant impact on the original space layout of the ship. It requires modifications to the ship's structure and the arrangement of shipboard accessories, and the structural modification is difficult. Moreover, the desulfurization tower has a complex structure, and the modification method of installing all components on the ship on-site one by one is inefficient, resulting in high installation costs.

[0018] As a preferred structure of the present invention, the ship has an upper deck, and the enclosure structure of the desulfurization system installation structure is disposed on the upper deck.

[0019] The second objective of this invention is to provide a ship with a desulfurization system installation structure that is easy to install, has minimal impact on the ship's existing structure, high installation efficiency, and relatively low installation cost.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] A vessel is provided, including a desulfurization system installation structure as described above, the vessel having an upper deck, and the bulkhead structure of the desulfurization system installation structure being disposed on the upper deck.

[0022] The beneficial effects of this invention are:

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0035] like Figure 1 and Figure 2 As shown, this embodiment of the invention first provides a desulfurization system installation structure, which includes a ship superstructure 1 and a desulfurization assembly 2. The ship superstructure 1 has an aft bulkhead 11. The desulfurization assembly 2 includes a bulkhead structure 21, a desulfurization tower 22, and a piping system. The bulkhead structure 21 is disposed on the upper deck 100 and includes a first bulkhead portion 211 and a second bulkhead portion 212. The first bulkhead portion 211 and the second bulkhead portion 212 are interconnected and arranged vertically. The first bulkhead portion 211 is fitted to the aft bulkhead 11, which provides stable support for the first bulkhead portion 211, maintaining the overall stability and structural reliability of the bulkhead structure 21. The desulfurization tower 22 is disposed inside the first bulkhead portion 211. This desulfurization system structure is simple and can be manufactured in sections. The desulfurization tower 22, the first bulkhead portion 211, and the second bulkhead portion 212 are manufactured separately and assembled before installation on the ship, thus allowing for overall installation and improving on-site construction efficiency. A passageway 213 is formed between the second bulkhead 212 and the aft bulkhead 11. The passageway 213 can accommodate shipboard accessories 200, including but not limited to container lashing bridges 201 and marine cranes 202. Both the container lashing bridges 201 and the marine cranes 202 can be located within the passageway 213 without requiring relocation or structural modification. This does not affect existing passage requirements or the internal structure of the ship's superstructure 1, maximizing the preservation of the ship's existing overall layout, improving installation efficiency, and effectively reducing installation costs. The piping system connects to the desulfurization tower 22 and is located inside the second bulkhead 212. The first bulkhead 211 and the second bulkhead 212 form an inverted L-shaped structure, which not only forms an integrated installation module to improve installation efficiency but also provides stable strength, effectively supporting the desulfurization tower 22.

[0036] Optionally, the first enclosure 211 and the rear enclosure 11 are welded together by fillet welds, which can maintain sufficient connection strength and has a simple processing technology and low construction cost.

[0037] In one embodiment, the desulfurization assembly 2 further includes a first deck platform 23 and a second deck platform 24. The first deck platform 23 is used to close the lower end of the first enclosure 211, and the second deck platform 24 is used to close the top end of the second enclosure 212. The desulfurization tower 22 is disposed on the first deck platform 23, and the second deck platform 24 has an opening for the desulfurization chimney 221 of the desulfurization tower 22 to pass through. The first deck platform 23 and the second deck platform 24 form a seal for the first enclosure 211, improving the stability and safety of the working environment of the desulfurization tower 22.

[0038] Furthermore, a chimney top plate 214 is provided on the top of the first enclosure 211. The chimney top plate 214 is located above the second deck platform 24. A chimney compartment 13 is provided on the top of the ship's superstructure 1. The chimney top plate 214 extends toward the ship's superstructure 1 to cover the chimney compartment 13. In this way, the desulfurization chimney 221 of the desulfurization tower 22 and the chimney compartment 13 of the ship's superstructure 1 share the chimney top plate 214, maintaining the overall aesthetics.

[0039] In one embodiment, the ship's superstructure 1 has a D-deck 12, and the first deck platform 23 and the D-deck 12 are located on the same horizontal plane. This satisfies the installation height requirements of the desulfurization tower 22 and facilitates access to the first deck platform 23 via the D-deck 12 for maintenance of the desulfurization tower 22. Moreover, the height of shipboard accessories 200 such as the ship's crane 202 and container lashing bridge 201 is generally below the D-deck 12, and the first bulkhead 211 being located above the D-deck 12 will not require modification of the lower deck 14.

[0040] In one embodiment, the desulfurization assembly 2 further includes multiple layers of supporting walls 25, which are spaced apart along the height direction within the enclosure structure 21. Preferably, the supporting walls 25 are made of grating flat plates, which are lightweight. The supporting walls 25 can increase the structural strength of the enclosure structure 21, and also facilitate maintenance of the desulfurization tower 22 and pipeline components at different heights through the supporting walls 25.

[0041] In one embodiment, the ship's superstructure 1 has multiple decks 14, which are spaced apart along the height direction. Optionally, from bottom to top, the multiple decks 14 are A deck, B deck, C deck, etc. The multiple supporting bulkheads 25 and the multiple decks 14 correspond one-to-one and are located in the same horizontal plane, which facilitates access to the bulkhead structure 21 through the decks 14 of the ship's superstructure 1 without the need for additional structures such as ladders.

[0042] In one embodiment, multiple containers 300 are arranged on the upper deck 100, clustered together to form a clearance space, within which the enclosure structure 21 is located. The containers 300 are easily movable, meeting the space requirements for installing the enclosure structure 21, and having a minimal impact on installation costs.

[0043] In one embodiment, a plurality of weight-reducing holes are provided on the second enclosure 212. The plurality of weight-reducing holes are spaced apart along the height direction of the second enclosure 212. Since the pipeline mechanism is installed inside the second enclosure 212, its own weight is relatively light. By providing weight-reducing holes on the second enclosure 212, the overall weight of the desulfurization component 2 can be reduced without affecting the overall structural strength.

[0044] The present invention also provides a ship, which includes the above-mentioned desulfurization system installation structure. The ship has an upper deck 100, and the bulkhead structure 21 of the desulfurization system installation structure is disposed on the upper deck 100. The bulkhead structure 21 includes a first bulkhead portion 211 and a second bulkhead portion 212 that are interconnected and arranged vertically. The first bulkhead portion 211 is fitted to the aft bulkhead 11, and a flow channel 213 for accommodating shipborne accessories 200 is formed between the second bulkhead portion 212 and the aft bulkhead 11. Thus, the bulkhead structure 21 forms an inverted L-shaped structure, which eliminates the need to move the shipborne accessories 200 or modify the ship structure, and does not affect the existing passage requirements. It maximizes the preservation of the ship's existing overall layout, which is conducive to improving the construction efficiency of the installation and effectively reducing the installation cost. The desulfurization tower 22 is disposed inside the first bulkhead portion 211. Such a desulfurization system structure is simple, can be manufactured in sections, and can be assembled before installation on the ship, thereby enabling overall installation and improving the construction efficiency at the installation site.

[0045] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. 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.
