Embodiment Construction

[0025] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] like Figure 1 to Figure 6 As shown, a sound-absorbing and guiding device provided by the present invention is installed on the side wall of the cabin, and is used to communicate with the gas pipeline and the cabin. 1, the cross-section of the air duct 1 is rectangular, and the plurality of silencing assemblies 2 are arranged at intervals on the opposite first side wall 11 and the second side wall 12 of the air duct 1. The first side wall 11 The sound-absorbing assembly 2 on the upper wall and the sound-absorbing assembly 2 on the second side wall 12 are misplaced, that is, along the flow direction of the gas in the air duct 1, there is a positio...

Abstract

The invention relates to a silencing and flow guiding device. The silencing and flow guiding device comprises an air pipe used for air circulation and a plurality of silencing assemblies arranged in the air pipe, wherein the multiple silencing assemblies are arranged on a first side wall and a second side wall opposite in the air pipe at intervals, the silencing assemblies located on the first side wall and the silencing assemblies located on the second side wall are distributed in a staggered mode, the first ends of the silencing assemblies are connected with the first side wall or the secondside wall, the second ends of the silencing assemblies extend into the air pipe, and the second ends of the silencing assemblies are spaced from the first side wall or the second side wall. The multiple silencing assemblies are arranged on the two side walls of the air pipe at intervals, the flowing direction of air is changed through the silencing assemblies, the silencing assemblies collide with the air and sound waves in the air pipe, the sound energy of the sound waves is consumed, then air silencing and noise reduction are achieved, and the cabin environment quality is improved.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing equipment, in particular to a sound-absorbing flow guiding device. Background technique [0002] In order to meet the ventilation needs of each cabin on the ship, the air is delivered to each cabin through the fan in the air compressor room. Due to the strong noise generated by the fan when it is working, and the noise generated by other mechanical equipment in the air compressor room will enter the cabin through the gas pipeline, causing serious hearing hazards to the crew working and living in the cabin. Contents of the invention [0003] The object of the present invention is to provide a sound-absorbing flow-guiding device, which can perform sound-absorbing and noise-reducing treatment on the circulating gas and improve the cabin environment. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] Provided is a sound-absorbing and guidi...
