Description
Technical field
The utility model relates to a kind of silencer.More specifically, the silencer that a kind of ventilation and air conditioning system uses is related to.
Background technology
All there is the transaudient problem of pipeline in air-conditioning system, existing processing mode is that the mode fixed a silencer on air-conditioning and ventilation shaft carries out noise elimination process.
Now be used in the silencer mainly resistive plate silencer in ventilation and air conditioning system.The subject matter of this type of silencer has following several respects:
1, structural volume is larger
Resistive plate silencer, mainly through filling sucting sound material in anechoic sheet and inwall, by producing acoustical absorptivity along journey Noise Penalty.Because in air-conditioning system, pressure is lower, just need this type of silencer to have the pressure loss little, draught area is large, and therefore, this type of air-conditioning system silencer is the larger structure of volume.
2, difficulty is installed
In addition because air conditioner pipeline usually distributes and furred ceiling, on gallery, installing space is limited, is not suitable for the silencer using the scale of construction large.Ventilation and air conditioning system is installed all non-decoration stage and is started to install, and muffler volume is comparatively large, usually breaks polishing metope after metope because silencer called in by needs, then mends finishing.
3, limited efficiency
Resistive plate silencer determines its soundproof effect according to its muffler section length, and because the scale of construction is limited, often soundproof effect is restricted.Dissipative muffler is obvious for high-frequency noise soundproof effect in addition, and single for Middle and low frequency noise, acoustic absorptivity is less than 0.6, and Middle and low frequency noise acoustical absorptivity is poor.
4, difficult in maintenance
The silencer that overall processing completes, because inner anechoic sheet and packing material are the fixing integrative-structures welded, the reasons such as along with the increase of service life, dust blocks, make moist, cotton is steady and sure, all can cause acoustic attenuation performance slowly to decline.Due to its fault of construction, generally can not carry out safeguarding or changing inner core, just must change whole silencer.
Utility model content
For the defect that above-mentioned prior art exists, the technical problems to be solved in the utility model is to provide a kind of silencer for ventilating system, this silencer adopts fabricated construction, disassemble as parts such as silencer outside plate, anechoic sheet, flange shrouding discs, convenient in carrying, install after Assembling with on ventilation duct of air conditioner, save carrying engineering, be applicable to the scene of part carrying limited space.
For solving the problems of the technologies described above, the utility model adopts following technical proposals:
A kind of silencer for ventilating system, comprise housing, anechoic sheet and flange plate, described housing is the double-decker of hollow, its inside is filled with sound-absorbing material, described anechoic sheet is the platy structure of hollow, and its inside is filled with sound-absorbing material, and described anechoic sheet is arranged on enclosure interior along airflow direction, described flange plate is provided with the water conservancy diversion arc matched with described anechoic sheet end, and described flange plate is fixedly connected with the two ends of described housing.
Preferably, the madial wall of described housing adopts porosity to be the microperforated panel of 25%, and the sound-absorbing material that described enclosure interior is filled is positioned at the inwall place of housing, is cavity near outer wall place.
Preferably, the outer wall of described housing is galvanized steel plain sheet, and inwall is corrosion resistant plate material.
Preferably, Z-type or C type support frame is provided with between the double wall of described housing.
Preferably, described sound-absorbing material is glass fabric parcel mineral wool.
The beneficial effects of the utility model are as follows:
The utility model effectively can optimize production structure, can mass production, and apolegamy is assembled into silencer.Soundproof effect is better than existing resistive plate silencer, and soundproof effect can reach 15dB/m.Medium and low frequency section acoustic absorptivity 0.7.Medium and low frequency acoustic attenuation performance makes moderate progress.To optimize structure mode, reduce silencer entirety and take up room.Silencer is damaged, failure member is replaceable, and service life is longer.
