Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a novel installation structure of a desulfurization tower. Background Art

[0002] In shipbuilding, desulfurization tower is a very important equipment, especially in ships with large fuel consumption. Because the fuel of ships is usually heavy oil, that is, oil with low ignition point and high sulfur content, and these sulfides will burn to produce sulfur dioxide, which is very harmful to the air environment and human health. In order to reduce these hazards, desulfurization towers must be used on ships to treat exhaust gas and reduce sulfur dioxide emissions.

[0003] For new ships, special designs can be made for the installation of desulfurization towers at the early stage of design. In conventional designs, desulfurization towers are generally arranged inside chimneys. At the early stage of design, the space of chimneys can be expanded to place desulfurization towers.

[0004] However, for ships that have already been put into operation, they can only be modified on the original basis to install a desulfurization tower. There is no suitable solution at present. Utility Model Content

[0020] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2As shown, a novel installation structure of a desulfurization tower includes a desulfurization tower 10 arranged on a ship. The ship includes an upper deck 11 with a chimney 14 and a lower deck 12 with a lifeboat ladder. A side bulkhead 13 is provided between the upper deck 11 and the lower deck 12, and a cabin 15 is provided below the lower deck 12. The desulfurization tower 10 is arranged outside the chimney 14, and a supporting platform 40 for supporting the desulfurization tower is provided below the desulfurization tower 10.

[0022] The support platform 40 is disposed above the lower deck 12 , and vertical support members 20 and oblique support members 30 are disposed between the support platform 40 and the lower deck 12 .

[0023] Two ends of the vertical support member 20 are fixed to the lower deck 12 and the supporting platform 40 respectively.

[0024] The upper end of the oblique support member 30 is fixed to the supporting platform 40 and the vertical support member 20 at the same time, and the lower end of the oblique support member 30 is fixed to the side bulkhead 13 and the lower deck 12 at the same time.

[0025] One end of the supporting platform 40 close to the chimney is fixed to the upper deck 11 .

[0026] The support platform 40 is a plate reinforcement structure, and includes a platform plate 41 and a strong cross beam 42. The strong cross beam 42 is fixed to the bottom of the platform plate 41. The tops of the oblique support members 30 and the vertical support members 20 are fixed to the strong cross beam 42. The bottom of the desulfurization tower is fixed to the platform plate.

[0027] In this embodiment, the strong cross beam 42 is a T-shaped material; the oblique support member 30 and the vertical support member 20 are both I-shaped steel.

[0028] The upper end of the web 31 of the oblique support member 30 is fixed to the strong transverse beam 42, and the lower end of the web 31 of the oblique support member 30 is fixed to the side bulkhead 13. The two ends of the web 21 of the vertical support member 20 are fixed to the strong transverse beam 42 and the lower deck 12 respectively.

[0029] The lower ends of the panels 32 of the oblique support members 30 are fixed to both the side bulkheads 13 and the lower deck 12 .

[0030] The connection between the panel 32 of the oblique support member 30 and the side bulkhead 13 and the connection between the panel 32 of the oblique support member 30 and the lower deck 12 are both rounded structures.

[0031] The upper end of the panel 32 of the oblique support member 30 is connected to the upper end of the panel 22 of the vertical support member 20 , and the upper end of the panel 32 of the oblique support member 30 and the upper end of the panel 22 of the vertical support member 20 are both fixed to the strong cross beam 42 .

[0032] The connection between the panel 32 of the oblique support member 30 and the panel 22 of the vertical support member 20 and the connection between the panel 32 of the oblique support member 30 and the strong cross beam 42 are both rounded structures.

[0033] The technical solution of the utility model is suitable for installing a desulfurization tower on a ship that has been put into operation, because the ships that have been put into operation are usually compactly arranged and do not have much space to arrange the desulfurization tower, so they can only be modified based on the original structure.

[0034] The technical solution of the utility model is to arrange a supporting platform on the side of the chimney to place the desulfurization tower. Since pillars are not allowed to be arranged in the cabin below the lower deck, the supporting platform is supported by a combination of oblique supports and vertical supports to effectively transfer the load of the desulfurization tower to the side bulkhead and the lower deck.

[0035] The utility model includes two parts. The first part is a support platform for supporting the desulfurization tower, which is a plate reinforcement structure. The second part is a combined pillar member for supporting the desulfurization tower platform, and the combined pillar member includes an oblique support member and a vertical support member. Since there are lifeboats and lifeboat ladders below, the combined pillar member used to support the support platform can only be open; and since there is a cabin below the combined pillar member, that is, there is a cabin below the lower deck, and pillars are not allowed in the cabin, the combined pillar member can only end at the lower deck; in order to reduce the load of the combined pillar member on the lower deck and improve the vibration performance after the desulfurization tower is installed, a combined pillar member composed of an oblique support member and a vertical support member is adopted to share part of the vertical load to the side bulkhead.

[0036] In this combined support member, a vertical I-beam support and an inclined I-beam support are used, that is, the vertical support member adopts a vertical I-beam support member, and the inclined support member adopts an inclined I-beam support member. One end of the web of the inclined I-beam support is pressed against the panel of the strong cross beam of the supporting platform, and the other end is pressed against the lower end of the side bulkhead. The panel of the inclined I-beam support is enlarged by a guide circle at both ends, which can ensure better connectivity, better load transmission, and better vibration performance.

[0037] The utility model mainly solves the problem of installing a desulfurization tower on an operating ship. The utility model sets a support platform to support the desulfurization tower, and sets a combined pillar component under the support platform, which does not affect the original lifeboat and lifeboat ladder and other equipment, and transmits the vertical load caused by the desulfurization tower to the hull bulkhead, reducing the load of the combined pillar component on the lower platform. It has been verified that the vibration strength and structural strength of this solution meet the requirements of the specification.

[0038] The utility model adopts an external mounting method to install a desulfurization tower by adding an independent platform and a combined support member without affecting the existing equipment and arrangement, and meets the structural strength and vibration requirements.

[0039] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
