Abstract
The invention relates to a tilting plate-honeycomb-type silencer. The tilting plate-honeycomb-type silencer comprises a silence box, sound insulation tilting plates and sound absorption insert plates; the tilting plates are perpendicularly provided with the sound absorption insert plates with the intervals of 200-250mm; the tilting plates are formed by combining three layers of materials including sound absorption materials, damping materials and sound insulation materials; the sound absorption insert plates are formed by combining perforated surface protection materials at the outer side and the sound absorption materials at the inner side; the tilting plates are in multiple structures; the sound absorption insert plates have the lengths of 1.5-2.0m and are perpendicular to the tilting plates, and have the widths of 1m. The silencer is suitable for silencing for air channel openings or fan openings with large cross sections, and has the characteristics of sound wave directivity, good silencing effect, corrosion resistance, convenience in installation and the like.
Description
Technical field
The present invention relates to environmental project noise control technique field, is a kind of hang plate-honeycomb silencer.
background technology
The noise producing in order to solve heavy in section pipeline, cooling tower air draft and Fan Equipment, has designed various silencers.Particularly cooling tower air-discharge silencer, generally adopt resistive chip noise elimination structure or baffle-type structure, but there are some defects in these silencers.Defect is: the large resistance of (1) inserted sheet density is large.(2) without sound wave directive property, affect soundproof effect.(3) use the many costs of material high.(4) simple hang plate sound deadening capacity is low.On November 15th, 2013, Northeastern University " Ministry of Education's Sci-tech Novelty Searching station " looks into new conclusion: have no with this project and look into new some air-discharge silencer employing ' hang plate-honeycomb fashion noise elimination structure ', identical bibliographical information.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hang plate-honeycomb silencer, and this silencer soundproof effect is good, and simple in structure, and soundproof effect is good.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: hang plate-honeycomb silencer, comprise that hang plate, inserted sheet and silencing case form, it is characterized in that: described hang plate is in silencing case top, inserted sheet is in hang plate vertical direction, and described inserted sheet spacing is 200-250 mm.This silencer is arranged on exhaust outlet or pipeline top.This silencer there is sound wave directive property and resistance low, soundproof effect is good.
Described hang plate-honeycomb silencer, is characterized in that: described hang plate is comprised of trilaminate material, both outside sound insulating material, inner side damping sheet and acoustic board combine.
Described hang plate-honeycomb silencer, is characterized in that: described sound absorption inserted sheet is comprised of two layers of material, both outer side perforation facing materials, and inner side sound-absorbing material combines.
Described hang plate-honeycomb silencer, is characterized in that: hang plate is multiplet, and spacing is one meter.
Advantage of the present invention is: the noise that it is widely used in environmental project is controlled.Silencer is frame structure, and sheet material is easy for installation.The features such as the applicable large section duct mouth of this silencer or blower fan mouth are eliminated the noise, and have sound wave directive property, and soundproof effect is good, anticorrosion, easy for installation.Overall structure is simple, and resistance is low, soundproof effect good.
The present invention is particularly suitable for cooling tower air exhausting soundproofing.
1. adopt 45 ° of hang plate direct sound waves to point to non-sensitive district;
2. absorb sound inserted sheet and hang plate is 90 °, and hang plate and inserted sheet group are cellular structure;
3. adopt silencing case buffering wind speed;
4. resistance is little, and sound deadening capacity is large.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local enlarged diagram in I place in Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is the local enlarged diagram in II place in Fig. 3.
In figure, 1. silencing case increases damping material, preservative treatment, and inner face sound absorption, plays sound insulation effect;
2. hang plate plays sound insulation, sonic guide effect;
3. resistive inserted sheet absorbs acoustic wave energy, consumes acoustic wave energy and forms vent passages;
The spacing of resistive is bought one for 200-250mm according to sound deadening capacity and Frequency Design;
4. vent passages air exhaust passage;
5. sound-absorbing material absorbs acoustic wave energy
6. damping material increases oise insulation factor
7. sound insulating material stops sound wave, sound insulation effect
8. perforated plate facing material, protects sound-absorbing material
9. the cotton sound-absorbing material that absorbs sound, consumes acoustic wave energy.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in drawings, hang plate-honeycomb silencer comprises that silencing case 1, hang plate 2 and inserted sheet 3 form, and in the vertical direction of described hang plate 2, has inserted sheet 3, has below silencing case 1.Hang plate 2 forms vent passages 4 with inserted sheet 3.
Between silencer and pipeline or Fan Equipment, with flange, connect or directly connect.Silencer is placed in pipeline opening or Fan Equipment interface.The geomery of silencer goes out mouth-shaped and size design according to pipeline opening or Fan Equipment.
First manufacture frame structure, then sheet material is installed, at hang plate vertical direction resistive of distributing installation at a certain distance, hang plate, resistive form an integrated member with silencing case.
During installation, integrated member is connected with pipe joint or Fan Equipment interface with standard component or directly connects.
