Description
Technical field
The utility model designs a kind of oil field strong noise equipment Brick wall sound absorption reduction device, belongs to oil field equipment field of noise control.
Background technology
Installing sound absorber on strong noise equipment factory building inner wall surface is the common method reducing reverberation noise in factory building, and it solves factory building noise as a kind of sound absorption reduction structure in every field and is widely used.
Wherein at the pump room of oilfield, water filling pump house, the equipment factory buildings such as compressor room, its mill construction major part is brick mix structure or color steel work, the metope lime of its brick mix structure is wiped one's face, smooth surface average sound absorption coefficient only 0.05, the surface of color steel work is more smooth, average sound absorption coefficient is less, noise waves passes through ground, metope, end faces etc. produce multiple reflections, the reverberation time of the general equipment room do not processed all is greater than 3.76S, room noise is caused to superpose because the reverberation time is long, thus cause sound pressure level to raise, and can effectively reach noise reduction object by increasing body of wall sound absorption coefficient.
Increase body of wall sound absorption coefficient mainly by installing porous absorption material additional on original wall body surface.Sound is propagated by vibration of media, when sound wave incident is to the air vibration excited during porous absorption material surface in micropore, relative motion is produced between air and solid grain, due to the viscosity of air, relative viscosity resistance is produced in micropore, make the kinetic energy of vibrate air constantly be converted into heat energy, make sound energy attenuation, thus reach the object of noise reduction.
Traditional factory building metope sound absorber is obvious to the reverberation eliminating effect of noise device high-frequency noise, but eliminates very limited to the reverberation of low-frequency noise, and the damping material of internal fiber shape is easy to the perforated plate through facing, thus affects indoor environment.The noise major part that oil field equipment produces when normal operation is Middle and low frequency noise, and the therefore traditional eradicating efficacy of factory building metope sound absorber to its reverberation is unsatisfactory.
The utility model is the above-mentioned deficiency solving traditional factory building metope sound absorber, provides a kind of acoustically effective ideal, safety and environmental protection, structure strong noise equipment Brick wall sound absorption reduction device in oil field simple, easy for installation for oil field all kinds of strong noise equipment factory building.
Summary of the invention
The utility model discloses a kind of oil field strong noise equipment Brick wall sound absorption reduction device, this oil field strong noise equipment Brick wall sound absorption reduction device comprises the former wall 1 of structure, damping vibration attenuation layer 2, air soundproof course 3, glass acoustical cotton plate 4, plain weave alkali-free glass wool cloth 5, aluminum perforated sound-absorbing plate 6 and lightgage steel joist 7, it is characterized in that described damping vibration attenuation layer 2 is completely affixed on the former wall 1 of described structure by glue; Be installed on described lightgage steel joist 7 by the described glass acoustical cotton plate 4 that described plain weave alkali-free glass wool cloth 5 wraps up; Described lightgage steel joist 7 nailing is fixed on the former wall 1 of structure; Between described glass acoustical cotton plate 4 and damping vibration attenuation layer 2, reserved cavity, forms air soundproof course 3; Described aluminum perforated sound-absorbing plate 6 uses as finish coat, be installed on structure outermost, and described aluminum perforated sound-absorbing plate 6 is fixed on lightgage steel joist 7.Aluminum perforated sound-absorbing plate in this device can serve as Helmholtz resonator in low-frequency range, can to stay in the air layer in advance acting in conjunction with structure, greatly can improve the sound absorbing capabilities of structure to low-frequency noise, thus make to be configured on Whole frequency band all there is higher acoustically effective, indoor absorption noise reduction is 8dB (A) to the maximum.
Oil field strong noise equipment Brick wall sound absorption reduction device is easy for installation, good looking appearance, and noise reduction is obvious, practical for oil field strong noise factory building.
