Furthermore, the number of the sectors is 6 or more than 6, so that the section perimeter of the noise elimination body 1 is greatly increased, and the noise elimination effect is improved.

Further, the noise reduction cotton comprises one or more of glass cotton or glass fiber cotton, and the glass cotton or the glass fiber cotton has the advantages of high temperature resistance, high hydrophobicity, sound absorption and noise reduction, so that the sound absorption effect is further improved.

Further, the installation shell comprises but is not limited to a metal frame, a civil engineering wall or a pipeline, and in practical application, the installation support can be fixed at the positions of the metal frame, the civil engineering wall or the pipeline and the like according to requirements, so that the application range is wide.

Further, the mounting shell can be in a shape including but not limited to a rectangle, a circle or a polygon, and the mounting bracket can be trimmed along the mounting position as required to meet the mounting requirements, so that the noise damper is fixed and can be adapted to mounting environments with various shapes.

Furthermore, a reinforcing member is arranged between the mounting brackets and is vertically connected with each mounting bracket, so that the stability of the mounting brackets is improved, and the noise elimination body is more stable.

Compared with the prior art, the invention has the beneficial effects that:

the petal-shaped silencing framework formed by jointing a plurality of sectors is arranged, so that the perimeter of the silencing body is greatly increased, and the silencing effect is improved; meanwhile, the silencing framework is made of a microporous plate, so that the sound absorption efficiency is improved; the cross section area of the flow guide cover on the silencing framework along the position direction of the connecting and mounting bracket is gradually reduced, and the wind resistance is greatly reduced by matching with the silencing bodies distributed in a matrix; in addition, the muffler body has simple structure and convenient assembly, and greatly reduces the assembly cost; the invention not only increases the section perimeter of the noise elimination body, improves the noise elimination effect, ensures the sound absorption efficiency, but also greatly reduces the wind resistance, has low assembly cost and improves the aesthetic degree of the noise elimination equipment.
