The cross-sectional area of access is greater than the cross-sectional area for the air inlet access that the air intake 11 is constituted.
By above structure, the reducer 1a can exhaust pipeline and the silencing means linkage section caliber size without
Under the premise of method expands, is installed convenient for exhaust pipeline and the silencing means, can more to be delivered to noise reduction section by exhaust pipeline
Wind speed at 1b gradually decreases, to reduce noise.Simultaneously under the effect of the reduction wind speed of aforementioned reducer 1a, wind passes through noise reduction
The action time available extension of section 1b, further enhances the sound-absorbing effect of the noise elimination part 2.In addition, reducer 1a is
Volume, the work area of noise elimination part 2 for increasing noise reduction section 1b provide structural condition.In addition, described being disappeared by the cabinet 1 with each
The cross-sectional area of the outlet air access constituted between line 2 is greater than the cross-sectional area for the air inlet access that the air intake 11 is constituted,
Air duct can be blocked to avoid noise elimination part 2, not influence normal air draft, heat dissipation of pipeline of fans headend equipment etc..The present embodiment as a result,
The silencing means of offer can effectively absorb big flow blower exhaust pipeline noise.
Specifically, the cabinet 1 can be pyramidal for side, it is easily installed fixation, there is preferable wind path to become into access, just
In heat dissipation, wind path is avoided to block.The air intake 11 is located at the upper bottom surface of side's frustum, and the outlet air end 12 is located at the side
The bottom surface of frustum.The cabinet 1 can be stainless steel material, and the reducer 1a, noise reduction section 1b can be an integral structure.
Each noise elimination part is intervally arranged along the length direction perpendicular to the cabinet.Each noise elimination part 2 can also be radial
Distribution, the structure can have played when sound wave passes through sound wave is preferably reflected, reflex, correspondingly, can have
Better sound-absorbing effect.The mounting hole for installation can be set in the air intake 11 and/or 12 end face of outlet air end.The cabinet
The lifting lug for installing the fixed cabinet 1 can be set in 1 outer wall.
Please refer to Fig. 4, Fig. 5, the noise elimination part includes that the noise reduction unit 21 made of noise reduction cotton material, setting disappear described
The nonwoven layer 22 of 21 two sides of sound unit, the panel 23 being arranged on the outside of the nonwoven layer offer on the panel 23 and disappear
Sound hole 24.
The nonwoven layer 22 can make 21 stable structure of noise reduction unit, facilitate sound-absorbing balance.Specifically, the nonwoven
The grammes per square metre of layer of cloth 22 can be 60~100 grams every square metre.
Wherein, the noise elimination part 2 further includes interconnecting piece 25, and the panel 23 is gripped by interconnecting piece 25, the connection
Portion 25 is fixedly connected with the cabinet 1.
Specifically, the interconnecting piece 25 grips panel 23,21 stable structure of noise reduction unit in noise elimination part 2 can be made,
The interconnecting piece 25 can be detachably fixed with the cabinet 1 by modes such as bolt, screw, sliding slot grafting, it is convenient for safeguarding more
Change noise elimination part 2.The interconnecting piece 25 can be stainless steel material.
Wherein, the ratio of 23 surface area of the sectional area summation of the bloop 24 and the panel is between 30~40%.
The bloop 24 can be circle, and aperture is 4~8 millimeters.The noise elimination part with a thickness of 50~70 millimeters, it is each described to disappear
Line 2 is spaced 40~60 millimeters.Actual tests show 2 structure of noise elimination part under above structure parameter, have better noise reduction effect
Fruit.In other alternative-embodiments, the bloop 24 or rectangular, diamond shape etc..
It is become larger by the cross-sectional area of the outlet air access constituted between the outlet air end 12 and each noise elimination part 2.Institute
The inner wall for stating cabinet 1 is bonded with the side wall of its immediate noise elimination part 2.The reflectivity of sound wave can be improved in above structure,
It is also avoided that the sound wave by passing through between 1 inner wall of panel 23 and the cabinet is transmitted to the external world without noise reduction simultaneously, improves noise reduction
Effect.
Wherein, the side of the noise elimination part 2 towards the air intake 11 is provided with air inlet guide part 3.
The air inlet guide part 3 can reflect sound wave, be interfered, and just have sound wave and 3 rear end of air inlet guide part
Noise elimination part 2 further come into full contact with, play better sound deadening.Described disappear can also be effectively reduced by entering the wind guiding 3 simultaneously
Wind path obstruction is reduced 2 side of line to the hindrance function of air draft.
Specifically, the air inlet guiding 3 can be stainless steel material.The air inlet guiding 3 can choose section in triangle
The wedge-shaped bar of shape, the acute angle of the triangle is towards the air intake 11.Of course, in other optional embodiments, institute
Stating air inlet guiding 3 also can according to need selection interface in the streamline structure of the shapes such as sub warhead.
Wherein, the noise reduction unit 21 is made of rock wool material.In the prior art, the air-cooled exhaust pipeline of generating equipment,
Since air carries high heat in exhaust pipeline, standard can not also adapt to high-temperature work environment.Rock wool has preferable
Sound-absorbing effect, while high temperature resistant are suitable for high-temperature work environment.Specifically, the suede weight density of the rock wool can be every cube
50~70 kilograms of rice.
