Micropore duct set is equipped in sound layer at interior surface layers, the micropore duct set is connected to one end of collection wind general pipeline, is collected
The other end of wind general pipeline is connected to external mute air box.
Further, the internal diameter of the micropore duct set is 15-25mm, micropore size 1-2mm.
Further, the interior surface layers are Zi in outside successively including perforated plate, glass-fiber-fabric, steel wire, the absorbent treatment
Including sound-proof material.
Further, the punching rate of the perforated plate is 15-25%.
Further, the micropore duct set is located in sound-proof material at interior surface layers.
Further, the outside of the absorbent treatment is also successively arranged damping layer and decoration panel.
Further, keel shoe is equipped in the absorbent treatment, the keel are erected between damping layer and decoration panel.
Further, there are two the air-inlet sound eliminators, it is respectively provided at the left and right sides of sound insulation of wall module-external.
Exhaust system is embedded in sound insulation module by the utility model, the air in Scatter Gather acoustic hood, is not needed another
Outer installation is not take up the useful space, at low cost.It is cooling in acoustic hood bottom air inlet using air-inlet sound eliminator, noise source is distributed
Heat bring acoustic hood top into, cover in air enter micropore collection wind in absorbent treatment after the interior surface layers of acoustic hood inner wall
Pipe, each micropore duct set import collection wind general pipeline after collecting heat dissipation air, empty after then being extracted by external mute air box；For
Dusty gas has good filter effect.The utility model is suitable for noise intensity height, noise source dust-laden, heat source and compares point
It dissipates, the higher place of gas emission request.
Detailed description of the invention
