The utility model discloses following beneficial effect has: simple structure, firm, noise cancelling effect is good, and the shock resistance is strong, and the operation is stable, safe, reliable, and it is convenient to overhaul, effectively eliminates the noise that produces among the ventilation system and guarantees that ventilation system has good acoustic performance.
Description
Technical field
The utility model relates to the silencer technical field of nuclear power station ventilation and air conditioning system, is specifically related to one
Plant the duct type clear sound device of antidetonation.
Background technology
It is currently installed in the duct type silencer of nuclear power station ventilation and air conditioning system, mainly to nuclear power station ventage
The noise that in road under the overall leadership, fluid produces plays elimination effect, reduces the noise that in air supply duct, fluid produces, to entering
One step improves the acoustical behavior of ventilating system important effect.When system fan runs, mechanical oscillation
And fluid, through being provided with the pipeline of silencer, by the noise elimination effect of silencer, will pass through in system pipeline
Fluid after sqouynd absorption lowering noise sends into nuclear island master control room, makes the noise level in end fluid exit meet master control room
The comfortableness demand of personnel, improve the working environment of master control room staff further.In view of nuclear power station owner
In control chamber ventilated air-conditioning system, owing to the vibration of system centrifugal blower is big, and air system plumbing sectional area is little,
Systematic air flow is big, and flow velocity is fast, and the ambient noise produced in system is big, it is impossible to meets master control room environmental condition and makes
With requiring.Meanwhile, equipment is installed in nuclear power station, to service life of equipment, operation stability, safety
Performance, anti-seismic performance are had higher requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sound construction, and acoustic attenuation performance is good, antidetonation
Ability is strong, the duct type silencer of antidetonation stable, safe and reliable.
The technical solution realizing the utility model purpose is: the duct type silencer of a kind of antidetonation, and it is special
Levying and be: include framework, silencing plate and more than one anechoic sheet, described silencing plate is located at framework both sides
Wall, described anechoic sheet is evenly arranged in framework inner chamber, described anechoic sheet include framework, anechoic sheet housing and
Being filled in the sound-absorbing material in anechoic sheet housing, described anechoic sheet housing is coated on framework；Described silencing plate
Including silencing plate housing and its interior sound-absorbing material of filling, between described silencing plate housing biside plate, it is provided with reinforcement
Muscle.
The front end of described anechoic sheet housing is provided with circular arc type deflector, and the front end of silencing plate housing is provided with arc line type
Deflector.
Described anechoic sheet is removably mountable in framework inner chamber.
The duct type silencer of a kind of antidetonation of the utility model has the advantages that simple in construction, firmly,
Good muffling effect, shock resistance is strong, stable, safe and reliable, and maintenance is convenient, effectively eliminates ventilation
In system produce noise and ensure that ventilating system has good acoustical behavior；Increase anechoic sheet, increase simultaneously
Add the integral rigidity of silencer, meet Fan Equipment vibration in master control room of nuclear power station ventilation and air conditioning system
Greatly, pipeline section amasss in environment little, that systematic air flow is big, flow velocity is fast and uses, to fluid stream in ventilation shaft
The noise of movable property life plays the effect of effective sqouynd absorption lowering noise, and the environment use meeting master control room staff is wanted
Ask.

Detailed description of the invention
As shown in Figure 1 to 4, the duct type silencer of a kind of antidetonation, including framework 1, silencing plate 2 and one
Above anechoic sheet 3, described silencing plate 2 is located at framework 1 two side, and described anechoic sheet 3 is evenly arranged in framework 1
In inner chamber, described anechoic sheet 3 includes framework 3.1, anechoic sheet housing 3.2 and is filled in anechoic sheet housing 3.2
Sound-absorbing material 3.3, described anechoic sheet housing 3.2 is coated on framework 3.1；Described silencing plate 2 includes eliminating the noise
Layer housing 2.1 and its interior sound-absorbing material 2.2 of filling, be provided with reinforcement between described silencing plate housing 2.1 biside plate
Muscle 2.3.
The front end of described anechoic sheet housing 3.2 is provided with circular arc type deflector 3.21, the front end of silencing plate housing 2.1
Being provided with arc line type deflector 2.11 so that it is tubaeform that air flue enters interruption-forming, gas-flow resistance is little, smooth and easy.
It is hole pattern plate that described silencing plate housing 2.1 is positioned at the side plate 2.12 of air flue side, described anechoic sheet housing 3.
The biside plate 3.22 of 2 is hole pattern plate.
Described anechoic sheet 3 is removably mountable in framework 1 inner chamber, dismounting, easy to maintenance, greatly reduce
Maintenance cost.
