Description

Noise reduction device for cooling tower

Technical Field

The utility model relates to a technical field that makes an uproar falls in the cooling tower especially relates to a device of making an uproar falls in cooling tower.

Background

Generally, a cooling tower is installed in a roof, an intermediate equipment floor, or a pit, which is often close to a living area or a working area of people, and noise is inevitably generated when the cooling tower is operated, causing noise interference to the life and work of people nearby. The noise generated by the cooling tower is mainly as follows: the noise, falling water sound, motor electromagnetic sound, mechanical friction sound and the like generated by the rotation friction air of the fan can not be eliminated if the cooling tower can normally run, and the defect of the cooling tower is inevitable. The utility model discloses a when eliminating to fall and making an uproar, kept business turn over wind meet the requirements again, ensured the high-efficient operation of cold effect of cooling tower, reached the effect of matter excellence, environmental protection.

Disclosure of Invention

In order to solve the technical problem, the utility model aims at providing a device of making an uproar falls in cooling tower, the device install sound equipment of inhaling additional in the periphery of cooling tower, absorb the noise is effectual, make the cooling tower ambient noise environment reach normal life and working standard, do not influence the normal operating of cooling tower simultaneously.

The purpose of the utility model is realized through the following technical scheme:

a cooling tower noise reducer, comprising:

comprises a sound-absorbing wall, a sound-absorbing ceiling and a sound-absorbing box; the sound absorption wall is used for enclosing the periphery of the cooling tower; the sound-absorbing ceiling is arranged at the top of the cooling tower; the sound silencing box is arranged at an air outlet of the air outlet channel of the cooling tower; the sound-absorbing wall and the sound-absorbing ceiling are used for absorbing the noise of the cooling tower in different directions.

Compared with the prior art, the utility model discloses an advantage can have as follows to one or more embodiments:

the sound-absorbing wedges effectively absorb and eliminate noise on the filling surface and the side surface of the cooling tower, and simultaneously keep smooth air inlet of the cooling tower;

the micropore sound-absorbing box effectively absorbs and eliminates the noise at the air outlet of the cooling tower, and meanwhile, the smooth air exhaust of the cooling tower is not influenced;

the structure is suitable for places with strict noise requirements, and effectively reduces noise.

fig. 2a and 2b are schematic views of the structure of the sound-absorbing wall.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1a and 1b and fig. 2a and 2b, the whole structure of the present invention includes: the sound absorption wall 1, the sound absorption ceiling 2 and the sound attenuation box 3; the sound-absorbing wall 1 encloses and shields the periphery of the cooling tower; the sound-absorbing ceiling 2 is arranged at the top of the cooling tower; the sound-reducing box 3 is arranged at an air outlet of the air outlet channel of the cooling tower; the sound-absorbing wall and the sound-absorbing ceiling are used for absorbing the noise of the cooling tower in different directions.

The sound-absorbing wall is of a double-layer structure, namely an outer wall and an inner wall, and the outer wall and the inner wall are composed of a plurality of silencing modules. Outer wall amortization module and interior wall amortization module take the dislocation to put to longitudinal distribution sets up the determining deviation between the module, and the centre can let the air inlet pass through smoothly, and the noise spreads to be absorbed when inhaling sound wedge 4. The hot-dip galvanized section bar is used as a support frame, and the sound absorption module is used for making a sound absorption wedge seat base shell by an aluminized zinc plate and is adhered with the sound absorption wedge inside. The sound absorbing wall mainly absorbs falling water sound in the horizontal direction of the cooling tower, when the noise is transmitted to the sound absorbing wall, the sound absorbing wall is split when entering the sound absorbing tip, the noise is eliminated, reflection is prevented, wind smoothly enters the sound absorbing wall through an air inlet channel arranged on the sound absorbing wall, the fresh air volume of the cooling tower is kept, and the effect of the cooling tower is guaranteed.

The sound-absorbing ceiling is of a single-layer wall structure, a hot-dip galvanized section bar is used as a supporting frame, an aluminum-plated zinc plate is used as a sound-absorbing wedge base and is bonded below the supporting frame, and noise is diffused to the sound-absorbing wedge and is absorbed. The acoustical ceiling is used for absorbing noise in a vertical direction, and also functions to prevent air from flowing back, and is configured in an overfire configuration to directly absorb noise.

The whistle box sets up to the rib formula structure to adopt hot dipping galvanized section bar to do braced frame, set up the determining deviation between the rib, the centre can let out the wind and pass through smoothly, and every fin outside sets up the casing, and the casing adopts micropore board 5, inhales the sound cotton 6 at casing internally mounted, and the noise gets into and is absorbed after inside. The amortization case main action is for absorbing noise, motor electromagnetism sound, mechanical friction sound etc. that fan rotational friction air produced, when the noise passes through the amortization case, through the micropore board, gets into the amortization cotton, is absorbed, and the amortization case is equipped with the air-out passageway simultaneously, does not influence the cooling tower and airs exhaust.

Although the present invention has been described in connection with the above embodiments, the above description is only for the purpose of understanding the present invention, and is not intended to limit the present invention. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
