Intermediate frequency silencing pot, the second silencing pot 113 are low frequency silencing pot.The preliminary noise elimination of high, normal, basic full frequency band is realized when entering the wind as a result,
To the further noise elimination of low middle high three frequency spectrums when double outlet air, dual sound-absorbing guarantees that silencer 1 is dropped with significant ground compound broadband
It makes an uproar noise elimination effect.
Preferably, the diameter of I 111A of aperture is 1~4mm, carries out noise elimination drop with the noise for high band 800-1600Hz
It makes an uproar；The diameter of II 112A of aperture is 4~10mm, is absorbed with the noise to Mid Frequency 300-800Hz；III 113A's of aperture
Diameter is 10~20mm, in this way, can eliminate the noise to the 300Hz noise below compared with low frequency.As a result, pointedly to low middle height
The noise of three frequency spectrums carries out comprehensive noise reduction, guarantees that deadening frequency band is wide and noise elimination noise reduction significant effect.
As it can be seen that the design of the air inlet sound attenuation assembly 11 of low middle high three frequency spectrums and double air outlet silencing components 12, realizes multiple
Wideband noise reduction is closed, improves noise elimination effect significantly.Meanwhile collaborating the setting of tee tube 13, be conducive to collecting air-flow into unification
Discharge, reduces the installation of air-exhausting duct.
In other embodiments, the air inlet sound attenuation assembly 11 of silencer 1 be also designed to include high frequency silencing pot 111,
First silencing pot 112 and the second silencing pot 113, air outlet silencing component 12 are designed as including that the first silencing pot 112 and second is eliminated the noise
Cylinder 113.Or the air inlet sound attenuation assembly 11 of silencer 1 is designed as including the first silencing pot 112 and the second silencing pot 113, outlet air
Sound attenuation assembly 12 is designed as including high frequency silencing pot 111, the first silencing pot 112 and the second silencing pot 113.Thereby it is ensured that eliminating the noise
Device 1 can be absorbed for the noise of high, normal, basic three frequency ranges, and compound broadband noise elimination noise reduction effect is good, while also acting as saving
Manufacture material and the purpose for reducing manufacturing cost.
