Abstract
The utility model discloses a kind of silencing apparatus being applicable to inflammable gas discharge.This silencing apparatus can be used for the exhausting silencer of the inflammable gas such as hydrogen, gaseous methane.This silencing apparatus principle of eliminating the noise is with interior to connect perforated pipe Extonsion Group identical, do not use sound-absorbing material, utilize resonance principle, make the phenomenons such as the sound wave of some frequency of pipe transmmision reflects, interference, thus reduce by silencing apparatus to extraradial acoustic energy, reach the object of noise elimination.This silencing apparatus arranges nitrogen blow-off's pipeline to expansion chamber, avoids inflammable gas to assemble in expansion chamber and sets off an explosion.
Description
Technical field
The present invention relates to a kind of silencer, the exhausting silencer of the inflammable gas such as hydrogen, gaseous methane can be applicable to, and flow resistance is less.
Background technique
Connect perforated tube silencer in traditional, be applicable to the control of Middle and low frequency noise, and flow resistance is less.But connect perforated tube silencer in traditional, its expansion chamber is a dead space of easily assembling inflammable gas, and the blowing of main line cannot be replaced this dead space, if for the discharge of inflammable gas, quick-fried sky may be caused even to explode, so be not suitable for the discharge of inflammable gas.
Summary of the invention
Object of the present invention is exactly Gonna breakthrough prior art, being optimized, can being applicable to the exhausting silencer of the inflammable gas such as hydrogen, gaseous methane to connecing perforated tube silencer in traditional.
For above-mentioned purpose, the present invention includes: entrance (1), outlet (5), main line (2), multiple expansion chamber (4), expansion chamber internal face and main line outer wall (3) open aperture, and the outer wall of punching rate > 25%, each expansion chamber arranges nitrogen blow-off road (6).In expansion chamber, sound-absorbing material is not set, nitrogen blow-off's pipeline is arranged to expansion chamber outer wall, avoid inflammable gas to assemble in expansion chamber and set off an explosion.
Meanwhile, expansion chamber and main line arrange pressure-measuring-point, avoid expansion chamber superpressure, and control nitrogen blow-off's flow by pressure reduction.
The invention has the advantages that: 1, make in optimization, to connect the discharge that perforated tube silencer is applicable to inflammable gas; 2, the acoustic attenuation performance internally connecing perforated tube silencer does not affect.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in the figure, this silencing apparatus comprises in entrance (1) and outlet (5), main line (2), multiple expansion chamber (4), expansion chamber internal face and main line outer wall (3) opens aperture, and the outer wall of punching rate > 25%, each expansion chamber arranges nitrogen blow-off road (6).
Before discharge inflammable gas, first nitrogen blow-off is carried out to main line and expansion chamber, blow down after terminating and can discharge inflammable gas, again main line and expansion chamber are blown down after inflammable gas discharge terminates.In addition, for different inflammable gass, also need the relevant criterion of discharging with reference to pipeline to use this silencing apparatus, as selected the compatible requirement such as silencing apparatus material, coutroi velocity.
Claims (1)
1. one kind is applicable to the silencing apparatus of inflammable gas discharge, comprise: entrance (1), outlet (5), main line (2), multiple expansion chamber (4), expansion chamber internal face and main line outer wall (3), it is characterized in that not arranging sound-absorbing material in expansion chamber, nitrogen blow-off's pipeline is arranged to expansion chamber outer wall, expansion chamber and main line arrange pressure-measuring-point, avoid expansion chamber superpressure, and control nitrogen blow-off's flow by pressure reduction.
