Description

Technical Field

[0001] The present invention relates to the technical field of passenger ship construction, in particular to a layout structure of a ventilation system in a cabin of a large passenger ship and the passenger ship. Background Art

[0002] Engine room ventilation on ships is designed to ensure the normal operation of machinery and equipment, prevent mechanical failures, maintain a good working environment, and ensure the comfort of crew members. It also provides sufficient ventilation to remove heat from equipment and maintain the required temperature in the engine room. It also needs to provide the combustion air necessary for combustion equipment.

[0003] The heat dissipation and combustion air volume of engine room equipment (such as main engines, generators, boilers, and heating cabinets) in large passenger ships is very high, resulting in very high airflow requirements for engine room supply and exhaust, and the resulting large engine room supply and exhaust ducting. To ensure air quality in the passenger area, engine room exhaust air on large passenger ships must be discharged through the engine room canopy to the top of the chimney, away from passenger activity areas.

[0004] like Figure 1 As shown in the figure, it is a simplified layout diagram of the engine room ventilation system of a large passenger ship before improvement. It can be seen from the figure that the engine room ventilation system consists of three parts: the engine room air supply system, the engine room combustion air supply system and the engine room exhaust system. Among them, the engine room air supply system consists of air inlet louvers, engine room supply fans (4 in the figure), engine room supply air ducts and fire dampers; the engine room combustion air supply system consists of air inlet louvers, engine room combustion air supply fans (3 in the figure), engine room combustion air supply ducts and fire dampers; the engine room exhaust system consists of fire dampers, engine room exhaust fans (4 in the figure), engine room exhaust ducts and exhaust outlet rodent-proof nets. As can be seen from the figure, the engine room air supply duct, the engine room combustion air supply duct, and the engine room exhaust duct all use black iron pipes (with a wall thickness of 5mm). Among them, the engine room air supply duct and the engine room combustion air supply duct pass through the entire engine room shed (in this case, the height of the engine room shed is about 30 meters), and the engine room exhaust duct passes through the engine room shed and chimney (in this case, the height of the engine room shed + chimney is about 40 meters). As a result, the air ducts of the entire engine room ventilation system are very heavy, which not only increases the cost, but also increases the light ship weight of the entire ship. It is also not conducive to the layout of the air ducts and needs to be improved. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, an embodiment of the present invention provides a cabin ventilation system layout structure applied to large passenger ships and a passenger ship adopting the above-mentioned ventilation system layout structure. On the basis of meeting the requirements of the design specifications, the wall thickness of the cabin supply air duct and the cabin combustion air supply air duct is reduced by adding a fire damper, and the characteristics of the cabin shed and the chimney are utilized to make the cabin shed and the chimney part of the cabin exhaust duct, and the cabin exhaust duct in the cabin shed and the chimney is eliminated, thereby achieving the purpose of reducing the weight of the duct, reducing costs and controlling weight.

Familiar and / or repetitive functions and structures are not described in detail to clarify the true intent based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any appropriate detailed structure.

[0031] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0032] The embodiment of the present invention provides a ventilation system arrangement structure for a large passenger ship cabin, such as Figure 2 As shown, including:

[0033] A cabin combustion blower 1 is located in a blower room 2 and communicates with a second cabin combustion air supply duct 5 located in a cabin canopy 4 via a first cabin combustion air supply duct 3. The other end of the second cabin combustion air supply duct 5 communicates with the extended end of a third cabin combustion air supply duct 6 that partially extends out of the cabin. The first cabin combustion air supply duct 3 is provided with a first damper 7, and the third cabin combustion air supply duct 6 is provided with a second damper 8 on the portion extending out of the cabin.

[0034] a cabin air supply fan 9, which is disposed in the fan room 2 and communicates with a second cabin air supply duct 11 disposed in the cabin canopy 4 via a first cabin air supply duct 10; the other end of the second cabin air supply duct 11 is communicated with an extended end of a third cabin air supply duct 12 that partially extends out of the cabin; a third damper 13 is provided on the first cabin air supply duct 10, and a fourth damper 14 is provided on the portion of the third cabin air supply duct 12 that extends out of the cabin;

[0035] By adding fire dampers to the air outlet sides of the engine room combustion fan 1 and the engine room supply fan 9 in the fan room 2, the engine room supply air duct and the engine room combustion air supply air duct inside the engine room shed 4 are downgraded to Class 10 spaces (same as the engine room shed 4). In this way, according to SOLAS (International Convention for the Safety of Life at Sea) Chapter II-2 Part C Regulation According to the requirements of specification 9 (2.2.3 table 9.1), the air ducts inside the cabin canopy 4 (cabin air supply duct and cabin combustion air supply duct) can be reduced from black iron pipes to galvanized iron sheets. That is, the first cabin combustion air supply duct 3 and the third cabin combustion air supply duct 6 both need to be made of black iron pipes, while the second cabin combustion air supply duct 5 can be made of galvanized iron sheets. At the same time, in this embodiment, the first cabin air supply duct 10 and the third cabin air supply duct 12 both need to be made of black iron pipes, while the second cabin air supply duct 11 can be made of galvanized iron sheets, thereby reducing the overall weight of the cabin air supply ducts and the cabin combustion air conditioning supply ducts.

[0036] a first cabin exhaust duct 15, partially extending out of the cabin, and provided with a fifth damper 16 on the portion extending out of the cabin, and a cabin exhaust fan 17 for exhausting air in the cabin at the end extending out of the cabin;

[0037] A second engine room exhaust duct 18 is provided at the connection between the chimney and the engine room cover 4 for connecting the chimney and the engine room cover 4. A sixth damper 19 is provided on the portion of the second engine room exhaust duct 18 located at the chimney. In this embodiment, multiple fire dampers are added at the boundary between the chimney and the engine room cover 4, that is, multiple sixth dampers 19 are provided, corresponding to the number of engine room exhaust fans. For example, at least four engine room exhaust fans 17 are provided, and at least four sixth dampers 19 are also provided. In addition, by utilizing the characteristics of the engine room cover 4 (category 10 space), in accordance with SOLAS (International Convention for the Safety of Life at Sea) Chapter II-2 Part C Regulation 9 (2.2.3 table 2), 9.1) According to the requirements of the specification, the cabin canopy 4 can be used as part of the cabin exhaust duct, thereby eliminating the cabin exhaust duct inside the cabin canopy 4 and reducing the weight of the duct system. That is, the gas exhausted by the cabin exhaust fan 17 passes through the cabin canopy 4 and is discharged from the chimney through the second cabin exhaust duct 18. Similarly, the chimney can be regarded as part of the cabin exhaust duct, eliminating the cabin exhaust duct inside the chimney, and reducing the weight of the duct system.

[0038] In some embodiments of the present invention, both the first cabin exhaust duct 15 and the second cabin exhaust duct 18 are made of black iron pipe.

[0039] In some embodiments of the present invention, there are two fan rooms 2 , which are respectively arranged on both sides of the cabin shed 4 , and each fan room 2 is provided with the cabin combustion fan 1 and the cabin air supply fan 9 .

[0040] Furthermore, in this embodiment, one of the fan rooms 2 is provided with at least two of the cabin combustion fans 1 and at least two of the cabin supply fans 9, and another of the fan rooms 2 is provided with at least one of the cabin combustion fans 1 and at least two of the cabin supply fans 9.

[0041] At the same time, in this embodiment, the fan room 2 is provided with an air inlet shutter 20 .

[0042] Furthermore, in some embodiments of the present invention, a rodent-proof net 21 is provided at the exhaust outlet of the wind damper provided inside the chimney.

[0043] It can be seen from the above technical solution that the layout structure of the cabin ventilation system for large passenger ships provided by the above embodiment of the present invention reduces the number and thickness of air ducts by respectively configuring wind dampers for the cabin combustion fan 1 and the cabin supply fan 9 in the fan room 2, which is beneficial to the space layout in the cabin shed 4; at the same time, it also reduces the weight of the air duct system, which is beneficial to the weight control of the ship and the design of the ship; in addition, the improvement made by the layout structure of the cabin ventilation system for large passenger ships provided by the above embodiment of the present invention is easy to implement.

[0044] An embodiment of the present invention also provides a passenger ship, which adopts the layout structure of the cabin ventilation system applied to large passenger ships as described in the above embodiment, and has all the beneficial effects of the above-mentioned layout structure of the cabin ventilation system applied to large passenger ships, that is, by respectively configuring wind dampers for the cabin combustion fan 1 and the cabin supply fan 9 in the fan room 2, the number of air ducts and the thickness of the air ducts are reduced, which is beneficial to the space layout in the cabin shed 4; at the same time, the weight of the air duct system is also reduced, which is beneficial to the weight control of the ship and the design of the ship; in addition, the improvement made by the layout structure of the cabin ventilation system applied to large passenger ships provided by the above-mentioned embodiment of the present invention is easy to implement.
