Abstract
The utility model relates to a environment-protecting and energy-saving noise abatement device, specifically relates to a novel voice stream silencer for civil and industry use. The utility model aims to resolve current technical problems and provide a silencer of high efficiency and small blockage ratio. The novel voice stream silencer comprises a silencer housing (2), a silencer element rack (1), a housing silencer layer (3), a connecting flange (4), a silencer component (5) and a silencer fixing device (6). The utility model is characterized in that a plurality of silencer components are distributed in a matrix; the silencer components are pipes in which sound-absorbing material is filled; the axes of the stream pipes are in a parallel arrangement in the direction of airflow; the stream pipes are fixedly disposed in the silencer through a rack. Compared with the prior art, the utility model is advantageous in that with silencers of the same length, the sound absorption surface area of an unit section is increased, sound absorption capability is improved and noise reduction effect is good.
Description
Technical field:
The utility model relates to the environmental protection and energy saving silencing equipment, specifically refers to a kind of industry and civilian novel sound flow filament silencing apparatus.
Background technique:
Present dissipative muffler is because design and the structural unreasonable following defective that has:
1, anechoic sheet generally is designed to fixedly slice structure, and slice, thin piece can't carry out secondary to be changed,
2, for big flow silencing apparatus, single-piece anechoic sheet area is excessive, and each position wind-engaging intensity differs, and anechoic sheet is fragile.
3, the silencing apparatus and the element of cooling down can only be with the single designs of process condition.Can't realize the seriation complete sets of products.
Summary of the invention:
For solving the problems of the technologies described above, flow filament silencing apparatus, its long service life, safe and reliable are provided to provide a kind of the purpose of this utility model.
The utility model is made up of muffler shell 2, silencer element support 1, shell silencing plate 3, adpting flange 4, muffler element 5 and silencing apparatus fixing device 6.It is characterized in that adopting matrix type a plurality of muffler elements of arranging, muffler element is a body, be filled with sound-absorbing material in the body, the axis of muffler element 5 is arranged in parallel along airflow direction, and muffler element 5 is fixedly mounted in the muffler shell 2 by silencer element support 1.
The utility model compared with prior art, under the silencing apparatus equal length, the sound absorbent surface of unit cross-sectional area is long-pending to be increased, acoustical absorptivity improves, excellent noise reduction effect, under the situation that guarantees same noise reduction, silencing apparatus length and volume can reduce, and the airflow area of unit cross-sectional area increases, and the flow velocity between sound absorbent reduces, pneumatic noise reduces, the pressure loss also reduces, thereby reduces the pressure of system fan, reduces the cost of whole ventilation system, whole silencing apparatus is resolved into the one by one little sound absorbent and the part of mounting bracket, convenient transportation and installation.The discharging of anechoic sheet dot matrix forms vent passages and is equivalent to rectangle dissipative muffler in parallel, when the vent passages of sound wave by forming by the anechoic sheet array, the energy of sound wave is consumed by anechoic sheet, air-flow can flow through thereby splendid to the noise elimination effect of wideband from passage, the pressure loss is little, thereby reaches the noise elimination ventilation purpose.

Fig. 2 is the utility model sound flow filament silencing apparatus anechoic sheet fixed structure schematic representation:
Embodiment:
With reference to accompanying drawing 1, accompanying drawing 2 as seen, the utility model is made up of muffler shell 2, silencer element support 1, shell silencing plate 3, adpting flange 4, muffler element 5 and silencing apparatus fixing device 6.Be provided with shell silencing plate 3 at muffler shell 2 internal surfaces, with silencing apparatus fixing device 6 muffler element 5 is fixed on the silencer element support 1, again silencer element support 1 is fixedly mounted in the muffler shell 2, when pneumatic noise is passed through in muffler shell 2, filling sucting sound material in the silencer element 5 of matrix arrangement and the muffler shell 2, noise is absorbed, and silencer element 5 its parallel axes are in airflow direction.Sound absorption time, do not increase that resistance is increased is excessive yet.Therefore, promptly energy-conservation, fallen and made an uproar again.
