Abstract
The utility model relates to the technical field of environmental protection, particularly a silencer, which is characterized in that the silencer is a metallic shell with an upper and a lower openings. The inner part is provided with a plurality of sound isolation plates which are provided with holes and are bent upwards with a certain bending angle; the sound isolation plates are arranged according to a sequence that a hole opening forms an approximate S-shaped passage. The silencer can be used for the silencing for industrial pipes with high pressure, high temperature and high velocity airstream and chimneys or a heat machine. The silencer has the advantages of simple structure and easy fabrication.
Description
The utility model relates to environmental protection technical field, is the baffler of high temperature, high pressure, high velocity air pipeline (calling three high pipelines in the following text).
The three high pipelines of producing now, using are not equipped with silencer, even silencer is arranged, and also because the outlet and the population of silencer are straight-through types, and performance is low, and erasure effect is poor, and noise is befouling environment still, harm resident's physical and mental health.
The purpose of this utility model provides a kind of baffler, and it is installed on the three high pipelines, owing to be provided with the air flue of some anechoic chambers and S shape, so good muffling effect can alleviate environmental pollution greatly.
The purpose of this utility model is achieved in that a shell, with some porose insulation boards on it, arranges orderly combining.Form sound proof chamber between plate and the plate, the aperture is arranged and is formed S shape air flue.
This baffler is made up of shell and inner core two-part.Its shell is the metal cylinder of shapes such as a circle, regular polygon, and import is arranged at the bottom, and outlet is arranged at top.Inner core is that porose on its that is adapted by some plate shapes and cross-sectional outer, the middle metal insulation board that upwards is converted into several angle rearranges in order.Form the anechoic chamber between plate and the plate, approximate S shape air flue is formed in the aperture.
This baffler is installed in three high pipeline exits, noise and air-flow enter baffler from pipeline, the S shape air flue of forming along insulation board rises, every through an anechoic chamber, a part of noise that just disappears, the noise reduction of consuming energy so step by step is at last when outlet enters atmosphere, air-flow becomes low pressure, low temperature, low speed, and noise just is lowered and eliminates.
This baffler can be applied to industry three high pipelines, also can be used for the noise reduction of heat engine exhausting pipe, and it is simple in structure, and is easy to manufacture, and effect is remarkable, and is very with practical value.
Description of drawings: Fig. 1, be the structural representation of this baffler; Fig. 2, be the longitudinal section sectional view of this baffler.Among the figure: 1, shell, 2, insulation board, 3, the anechoic chamber, 4, the aperture, 5, S shape air flue, 6, import, 7, outlet.
Below describe the structure and the working procedure of this baffler with reference to the accompanying drawings in detail.See Fig. 1, the structural representation of this baffler: foursquare cylinder shell 1 has outlet 7, import 6 up and down.Having among the shell 1 somely has aperture 4, centre to have the sound insulation sheet 2 of certain knuckle to arrange in certain sequence on it, and it is that the aperture is arranged and formed S shape air flue 5 in proper order, forms anechoic chamber 3 between every two adjacent sound insulation sheets, plays the power consumption sound deadening.See Fig. 2, in the cut-away view of baffler longitudinal section, further illustrate some insulation boards 2 and arrange in certain sequence that the aperture 4 of multi-disc sound insulation sheet forms S shape air flue 5.Noise is diffused into each anechoic chamber after entering baffler from baffler import 6, enters S shape air flue again, promptly by noise reduction.
Claims (1)
- A kind of baffler of being made up of shell and inner core has aperture, the middle insulation board that certain knuckle is upwards arranged on its that it is characterized in that inner core adapts by some plate shapes and shell, makes the aperture form rearranging in order of approximate S shape passage.
