Embodiment Construction

[0055] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the following examples.

[0056] see Figure 1-4 understand the invention. in, figure 1 is a top-down view, figure 2 reflects the orientation of the structural air duct 100 in use, figure 2 The lower end of the mid-wind pipe body 1 is used to connect the deck or segment boundary 200 .

[0057] An embodiment of the present invention provides a structural air duct for a ship with a sound-absorbing device, which is applied in a ventilation system of a ship, and is especially suitable for a large ship. Preferably, the structural air duct 100 is arranged between the decks on both sides of the ship. During the construction process, the structural air duct 100 between any two decks is operated separately, and then the adjacent structural air duct 100 is welded and fixed.

[0058] The structural air duct 100 includes an air duct main body 1 , ...

Abstract

The invention discloses a ship structural air duct with a silencer, a mounting method thereof and a ship. The structural air pipe comprises an air pipe body, a first supporting part, a plurality of silencing piece single bodies and a second supporting part. The first supporting component is transversely arranged in the air pipe body and fixed to the first end. The silencing piece single bodies are fixedly connected to the air pipe body and / or the first supporting component, and the adjacent silencing piece single bodies are arranged at intervals in the direction perpendicular to the axial direction of the air pipe body. The second supporting part is arranged in the second end of the air pipe body and fixedly connected with the air pipe body and the silencing piece single bodies. Compared with the prior art, the large-size silencing piece single body is low in cost and high in operability, the assembling difficulty of installing a structural air pipe on a ship body is reduced, the installing steps are simplified, the assembling efficiency is improved, the silencing piece can be better fixed, and the reliability of the silencing piece single body is improved.

Description

technical field [0001] The invention relates to a structural air duct of a marine ventilation system, in particular to a structural air duct with a sound-absorbing device, an installation method thereof, and a ship. Background technique [0002] In the marine ventilation system, the noise reduction equipment is an auxiliary device installed in the structural air duct to eliminate the noise generated when the equipment is working. At present, it is usually realized by installing a silencer in the structural air duct, and the silencer needs to be installed in two sections of the structure position between the seams. [0003] As the tonnage of various types of ships increases, the capacity of ship ventilation becomes larger and larger, and the size of the corresponding hull structure air duct is also huge, which requires a larger silencer to realize. However, in the actual production process, it is found that on the one hand, it is difficult to match a large silencer that meet...
