Description
Technical field
The invention belongs to field of Environment Protection, and in particular to a kind of body of revolution ventilation sound arrester of preventing and treating noise.
Background technology
The noise that the equipment such as water tower, cooling tower, central air-conditioning, transformation station, industrial steam turbine of drying in the air are produced when running is near
Resident, school and Office Area produce larger noise pollution.At present mainly by soundproof wall or blimp to sonic propagation way of making an uproar
Footpath is stopped, so as to reach the purpose of governing noise pollution.But ventilation and heat, soundproof wall are needed when being run due to the said equipment
Or blimp, while noise problem is solved, the ventilation and heat to equipment is impacted.
The content of the invention
The present invention is intended to provide a kind of structurally simple, economical practical body of revolution ventilation sound arrester, it can be in reduction
While noise pollution, the function of ventilation and heat is realized.
To reach above-mentioned purpose, the present invention uses following solution：A kind of body of revolution ventilation sound arrester, it is characterized in that
Sound panel is that sound-absorption hole is provided with body of revolution, body of revolution sound panel, filling sucting sound material inside sound-absorption hole.
The vent passages of a fixed gap are formed between sound panel, due to the special cross-section shape and array group of sound panel
Close, blocking is still formed to noise transmission approach, the effect of ventilation and heat is reached while noise reduction.
The body of revolution sound panel in the form of array combination to be arranged on support frame.
One end of body of revolution is tip, and the other end is round end；It is tip towards noise source side, dorsad noise source side is
The a diameter of 1mm-25mm for the sound-absorption hole opened in round end, sound insulation plate face, the perforated area of sound-absorption hole for sound insulation plate suqare 20%-
80%。
Sound panel is arranged in certain array combination, and the vent passages of a fixed gap are formed between sound panel.
The present invention passes through the body of revolution shape and array combination of sound panel so that the characteristic impedance of tip end face is close to air
Characteristic impedance, is progressively transitioned into the characteristic impedance close to sound-absorbing material, so as to reach highest sound absorption effect.On sound panel
Sound-absorption hole and the porous fibre sound-absorbing material of filling, can effectively reduce noise.Space is formed between sound panel simultaneously, to noise
Route of transmission still forms certain blocking, can be with ventilation and heat while noise is prevented and treated.
Compared with prior art, the invention has the advantages that：
1st, the present invention effectively increases noise reduction by the body of revolution shape and array combination of sound panel, economical and practical.
2nd, form space between sound panel of the present invention, due to body of revolution shape sound panel and array combination, to noise transmission
The space that approach is still formed between blocking, sound panel can be with ventilation and heat.
