Abstract
The invention discloses a multi-layer muffler. The muffler has the following beneficial effects: three layers of mufflers are arranged, the boiler gas passes through an inner-layer muffler, an intermediate-layer muffler and an outer-layer muffler in sequence and can undergo twice expansion depressurization and simultaneously the multi-layer muffler can prevent the garbage from being ejected outwards; therefore the multi-layer muffler has the characteristics of good muffling effect and slag removal effect; and the multi-layer muffler is horizontally installed and is suitable for muffling the wash pipes of bigger boilers.
Description
Technical field
The present invention relates to a kind of silencer, relate in particular to a kind of silencer that is used for administering washing pipe process noise and waste processing.
Background technique
Silencing apparatus is mounted on the air-flow path of aerodynamic force equipment (as blower, air compressor) or the device of the reduction noise in the inlet and exhaust system.Silencing apparatus can stop the propagation of sound wave, allows the air communication mistake, is the effective tool of control noise.The kind of silencing apparatus is a lot, but studies carefully its noise elimination mechanism, can be divided into six kinds of main types to them again, i.e. dissipative muffler, reactive muffler, impedance complex formula silencing apparatus, micropunch plate muffler, micropole diffusor and active silencer.
Dissipative muffler mainly utilizes sound-absorbing porous material to reduce noise.Sound-absorbing material is fixed on the inwall of air-flow path or and in pipeline, arranges, just constituted dissipative muffler according to certain way.When sound wave entered dissipative muffler, a part of acoustic energy rubbed and changes into thermal dissipation to fall in the hole of porous material, and the sound wave by silencing apparatus is weakened.Dissipative muffler just looks like the pure resistance circuit on the electricity, and sound-absorbing material is similar to resistance.Therefore, people just call dissipative muffler to this silencing apparatus.Dissipative muffler is eliminated the noise effective, relatively poor to low frequency noise elimination effect to medium-high frequency.
The silencer that is used to eliminate this noise like has at present had a lot, and for example the patent of patent No. CN85202488 promptly provides a kind of structure statement of account, full steel structure, the accurate silencing apparatus of control media flow and noise.But this silencing apparatus not too is suitable for washing pipe eliminates the noise.Also there is following shortcoming in existing silencing apparatus: sound deadening capacity has narrow limitation, and generally below 30 decibels, the rubbish major part all is discharged in the air, pollutes, and Pen Chu rubbish also may be hurted sb.'s feelings simultaneously.
Though there is many similar silencing apparatuss institute that behaves to know at present, but in the slight change of apparatus structure form, will make the noise elimination effect be improved, therefore how its structure be improved, to improve the noise elimination effect, remain the technical problem that is worth solution in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of multilayer silencing apparatus, it can be used for the improvement of washing pipe process noise and rubbish, can further improve the noise uptake, and its structural design is ingenious simultaneously, and fabricating cost is low.
For achieving the above object, the present invention has taked following technological scheme: a kind of multilayer silencing apparatus, wherein, described muffler body is made up of internal layer silencing apparatus, middle level silencing apparatus and outer silencing apparatus.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: described internal layer silencing apparatus is the macropore silencing apparatus, and the middle level silencing apparatus is the macropore silencing apparatus, and outer silencing apparatus is a micropole diffusor.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: the aperture of described internal layer silencing apparatus is 3.5cm～4.5cm.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: the aperture of described middle level silencing apparatus is 2.5cm ~ 3cm.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: described internal layer silencing apparatus and middle level silencing apparatus and outer silencing apparatus being connected and fixed with connecting plate.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: described connecting plate is a porous slab, and described aperture is 2.8cm～3.5cm.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: described support connects silencing apparatus and ground.
As a kind of preferred version of multilayer silencing apparatus of the present invention, wherein: described drain port is positioned at outer silencing apparatus bottom.
Traditional method is at the improvement of noise, and maximum sound deadening capacity is only about 30 decibels.Adopted the silencing apparatus of structure of the present invention, owing to be provided with three layers of silencing apparatus, boiler gas is successively by internal layer silencing apparatus, middle level silencing apparatus and outer silencing apparatus gas, and can reduce pressure through twice expansion, the multilayer silencing apparatus can stop that also rubbish outwards sprays simultaneously, therefore it is effective to have noise elimination, the scarfing cinder good effectiveness.The present invention is that level is installed, and it is applicable to than the washing pipe of cauldron and eliminates the noise.
